A digital convergence apparatus detects the presence/absence, frequency and the number of scanning lines of inputted synchronizing signals, performs an interpolation between adjusting points corresponding to the detection signal to prepare a correction data, and performs a cursor display of a center position between adjusting points, extrapolating operation control and difference data storage, writing of the same data into n-planes, and time sharing of the interpolation processor so as to accommodate multimedia with a high accuracy.

A folding box made of synthetic resin capable of being stably held without slipping by securely grasping it even if any side-portion of the hexahedron of the box is grasped by both hands. The folding box comprises a square tubular side-wall component part (3) formed by foldably connecting the adjacent side end parts of hard synthetic resin four side plates (1) to each other through side plate connection hinge parts (2), a bottom plate component part (6) formed by foldably connecting a hard synthetic resin bottom piece (4) to the lower sides of the plurality of side plates (1) through bottom piece connection hinge parts (5), and a cover component part (7) formed by foldably connecting a hard synthetic resin cover piece (15) to the upper sides of the plurality of side plates (1) through the cover piece connection pin parts (10). Soft synthetic resin non-slip parts (13) exposed to the outside are fitted to the hexahedron near the sides on one or both of the faces of the hexahedron perpendicularly adjacent to each other through the sides thereof. The non-slip parts are fitted to the hexahedron near all the sides thereof.

PURPOSE:To prevent a program from running away when stacks overflow by outputting a detection signal when the value of a stack pointer reaches a prescribed address and generating interruption when the detection signal is outputted. CONSTITUTION:A limited address 17 is decided by a single chip microcomputer. Since the address 17 of the stack being the object of interruption is '0', the stack 7 is arranged from the address '0'. The initial value of the stack pointer 5 sets the size of the stack 7. When the value of the pointer 5 comes to the address '0' while the program is executed, interruption occurs, and an interruption routine 8 starting from the address which is set in an interruption vector 10 is executed. In the routine 8, a necessary error processing is executed. Thus, the error processing can be executed by the interruption routine when the stacks overflow, and the runaway of the program is previously prevented.

PURPOSE: To largely increase the effective processing speed of items in a stack by responding to a pop (reading) command and increasing the present pointer according to length of an item in the top position of a stack in the present. CONSTITUTION: A graphic system 10 includes one or more peripheral devices such as a graphic processor 12, a display monitor 14, an alphanumerics keyboard 16, a graphic channel controller 18, and the like. In this case, the present pointer indicating the present top of a stack in a stack region is stored, and in response to a push command, an item is written in a storage place of a stack region having lower address than the present top of the stack, a stack pointer is decreased, and in response to a pop command, an item being in the present top of the stack is read from the stack region, and the present pointer is increased. Thereby, effective processing speed of an item in the stack can be increased.

Stack controlling apparatus and method

PROBLEM TO BE SOLVED: To provide a container which can be used respectably and sanitarily without exposing the upper face of the opened edge at the upper edge of a side wall and in which the contact force of each lid can be reduced when adjacent containers are in contact to each other and the floating of the lid can be prevented SOLUTION: The container made of a foamed resin comprises a container body 10 opened upward and a lid 20 having a circumferential edge 21 placed on the upper face 11a of the opened edge 11 at the upper edge of the side wall of the container body 10 and an inner fitting part 22 to the opened edge 11, wherein the external form of the lower edge of the circumferential edge 21 of the lid 20 is the same in the plane as the external form of the opened edge 11 of the container body 10 and the peripheral side face of the circumferential edge 21 of the lid 20 inwardly inclines upward to form a tapered inclined plane 23 COPYRIGHT: (C)2011,JPO&INPIT

PURPOSE:To prevent a system from running away by applying an interruption and stopping the system when 1st and 2nd check means decide that a stack position is out of a stack area or that the border flag of a task is broken. CONSTITUTION:A scheduler 5 checks whether or not the stack positions of tasks A-C are beyond the borders of the stack areas of tables 61-63 indicating the states of the tasks A-C when an interruption S1 for the tasks A-C under control is initiated. When they are within the ranges, it is checked whether or not the border flags of the stack areas 71-73 are rewritten. When the stack positions of the tasks A-C are beyond the borders of the stack areas or when the border flags of the stack areas 71-73 are rewritten, the system is stopped. Consequently, an initial system runaway is precluded and which of the task A-C is broken is known.
