A casing is provided for a reflection measurement device emitting a scanning beam and receiving an echo beam caused by reflection of the scanning beam at an object, and detecting a distance to the object in response to the received echo beam. The casing has a window for conducting a beam, and a protective member being transparent to the beam and covering the window from an inside. A predetermined range through which the beam passes is provided in the window. An interval between a lower edge of the beam pass range and a lower edge of the window is greater than an interval between opposing edges of the beam pass range and the window which differ from the lower edges thereof.

A broadcast router (100) includes a router matrix (102a) having input and output sides (102a-1 and 102a-2). Coupled to the input side (102-1) of the router matrix (102a) are first and second reference inputs (146 and 148). The first reference input (146) is configured for application of a first reference signal thereto while the second reference input (148) is configured for selective application of either a second reference signal or a redundancy of the first reference signal thereto. The broadcast router (100) further includes N inputs, M outputs and a routing engine (134), coupled between the N inputs and the M outputs, for applying selected ones of the N inputs to the M outputs. A reference select circuit (144) is coupled between the first and second reference inputs (146 and 148) and the routing engine (134).

Broadcast router configured for alternately receiving multiple or redundant reference inputs

PURPOSE: To secure the synchronism between the information processing parts by providing a clock generating means into each information processing part forming an information processor to produce a clock signals having the phase synchronism with an original clock signal. CONSTITUTION: The double phase clock signals K1 and K2 produced inside an information processing part 1 or 2 has the phase synchronism with an original clock signal K. Therefore the signals K1 or K2 in a certain information processor is synchronous with the signal K1 or K2 of another information processor via the signal K. At the same time, the signals K1 and K2 of each information processor have the phase synchronism with the signal K and also have the prescribed duties. As a result, a clock signal having a small clock skew and an accurate duty is supplied into each information processor. COPYRIGHT: (C)1988,JPO&Japio

Apparatus and system for information processing

PURPOSE: To improve the reliability of a system by providing a duplex synchro nizing device and a duplex constitution in-system device and connecting selectors crosswise. CONSTITUTION: Connecting constitution is formed in such way that the synchro nizing devices 1-0 and 1-1 output system clocks from system clock generating parts 2-0 and 2-1 selectively by the selectors 3-0 and 3-1, and the selectors 3-0 and 3-1 are connected to the selectors 5-0 and 5-1 in the in-system devices 4-0 and 4-1 crosswise. Since switching between a system in use and a standby sys tem can be performed independently on the synchronizing devices 1-0 and 1-1 side, and the in-system devices 4-0 and 4-1 side, a maintenance work can be performed easily. Also, since it is possible to control selectively the distribution path of the system clock, the distribution of the system clock can be continued without generating system down, when a various kinds of faults including a cable fault, etc., and generated. In this way, the reliability of the system can be improved than ever. COPYRIGHT: (C)1988,JPO&Japio

System clock distributing system

PURPOSE:To make it unnecessary to adding a circuit corresponding to a compensating circuit in a multiplier circuit, etc., in the system which is operated by clocks from a clock supply unit provided commonly for plural digital devices. CONSTITUTION:Digital devices 1 and 2 receive distribution of clocks from reference clock source 3, and clocks are multiplied by 11 and 21 and form internal clocks 13 and 23 and are supplied to information transmission/receiving circuits 14 and 24 and circuits 16 and 26 taking interface to them. In respect to distribution cable 4 for reference clocks, length between device 1 and clock source 3 is equal to length between deivce 2 and clock source 3. Since reference clocks 12 and 22 distributed by equal-length distribution cable 4 operate circuits 14 and 24 directly, advantages of reduction of irregularity in phase difference and considerable relaxation of restriction for length of information transmission cable 5 for interdevice information transmission are obtained.

Clock distribution system

PURPOSE:To make it possible to form a space switch part in no consideration of phase variance, by making needless a flip-flop which latches burst communication information into the space switch part in the time division exchange devide. CONSTITUTION:Burst communication information from time switch circuits 21 and 22 are applied as inputs 1 and 3 to space switch part 35 of space switch part 25, and meanwhile, burst clocks 2 and 4 generated by latch timings T1 and T2 and burst timings T10 and T20 are applied to space switch circuit 36. Space switches 35 and 36 distribute input burst communication information and burst clocks to time switch circuits 23 and 24. Consequently, the space switch part does not latch burst communication information conventionally but burst communication information and burst clocks pass through space switch parts synchronously with each other, so that space switch parts can be formed in no consideration of measures against phase variance in space switch parts.

Time division exchange system

PURPOSE:To reduce a cost and a space by constituting a low-speed clock break detection circuit with only digital elements by utlizing points where high-speed reference clocks and low-speed frame clocks are sent from a master clock unit. CONSTITUTION:The existence of coming of frame clocks are stored in shift registers 72 and 73 by anti-phase clocks of the reference input, which pass through gate 71, while shifting them successively. The output is inputted to exclusive OR gate 74, so that the output of reference input 2-clock components gate 74 becomes high- level after the frame clock comes. At this time, counter 78 is reset and does not reach 1023; however, when even one of frame clocks lacks, counter 75 reaches 1023, and a pulse appears at the 1023 output of decoder 76 to set a flip flop through OR gate 79, and alarm is indicated to software similarly to reference clock break.

Clock break detection circuit

PURPOSE:To detect a stack fault of a channel, by collating a signal pattern which is extracted out of a specified channel of an outgoing highway with a signal pattern which is generated from a pattern generating means. CONSTITUTION:A pilot pattern generating circuit 201 produces a specified signal pattern and a signal pattern having a complement relation with said specified signal pattern alternately for each frame in the form the test patterns. A pilot pattern checking circuit 202 collates a signal pattern of the pilot channel on an outgoing highway 108 with a test pattern on a signal line 203. Then an error signal is fed to a signal line 110 when no coincidence is obtained from the above- mentioned collation.

Pilot testing system

PURPOSE:To facilitate an easy increment and extension of the transmission system by giving the switching and correction to the transmission delay amount in accordance with the installation distance between the master and slave devices CONSTITUTION:The long-distance or short-distance transmission is decided according to the distance between the master and slave devices And for the long-distance transmission from master device PE, the information transmitted at the same time of the A-series clock such as A0 is received at each slave device CE at the different time of the B-series (long distance (a), short distance (b)) Then with the different set delay amount, for example, with delay of T second in the case of the long distance and 2T seconds in the case of the short distance each, the information is taken into device CE at the same time such as C3 of the C-series clock And the vice versa for the transmission carried out from the slave to master station Thus the delay amount is switched according to the distance between the master and slave devices, thus facilitating the system extension
