Electrodeless discharge lamp

Abstract: An electrodeless fluorescent lamp operating at relatively low frequencies (50-500 kHz) whereby a ferrite core is utilized to generate the necessary magnetic and electric fields to maintain the discharge where the core material is Mn-Zn type combination due to its low power losses, 400 mW/cm3, in the frequency range of 50-100 kHz and magnetic field strengths of 150 mT Furthermore, the material may cover a variety of atomic percentages of Mn and Zn added to Fe2O3 base to obtain favorable grain boundary and crystalline structure, resulting in a practical ferrite core material, having a Curie temperature greater than 200°C Such material enables the operation of electrodeless fluorescent lamps with powers ranging from 10W to about 250W at low frequencies, as mentioned above, in such a manner that ferrite core losses constitute less than 20% of the lamp power and heat generated by core losses is minimized

Compiler, compiler apparatus and compilation method

Abstract: An operator definition file 102 and the like included in a source program 101 and a compiler 100 that translates the source program 101 into a machine language program 105 are provided. The operator definition file 102 includes definitions of various fixed point type operators by class definitions. The compiler 100 can generate effectively advanced and specific instructions that a processor executes and make improvements through expanding functions and the like without repeating frequently upgrading of the version of the compiler itself. The compiler 100 is made up of an intermediate code generation unit 121 that generates intermediate codes, a machine language instruction substitution unit 122 that substitutes the intermediate codes referring to classes defined by the operator definition file 102 with machine language instructions and an optimization unit 130 that performs optimization targeting the intermediate codes including the substituted machine language instructions.

Electronic ticket, electronic wallet, and information terminal

Abstract: A network electronic ticket 1003 is provided in an electronic ticket 1000. Start page data 1016, a ticket owner secret key 1017, an electronic ticket possession certificate 1018, and a network service program 1019 are provided in the network electronic ticket 1003, the network service program 1019 controls various types of processing and an electronic ticket storage terminal, and the ticket owner secret key 1017 and the electronic ticket possession certificate 1018 are used for authentication processing with an information providing apparatus on a network, whereby it is made possible to connect to the network from the electronic ticket itself and receive information service.

Plasma processing apparatus

Abstract: PROBLEM TO BE SOLVED: To provide a plasma processing apparatus for plasma-processing a substrate, which is suitable for an experiment, a development work and a low production, while reducing troubles about transportation of the substrate in the plasma processing apparatus. SOLUTION: The plasma processing apparatus comprises a processing chamber; a preliminary chamber which is arranged in a tilting direction to a center axis of the processing chamber and is made to communicate with the processing chamber so as to be interruptable; a substrate electrode part having a substrate-mounting face capable of mounting the substrate on the top surface; a substrate electrode-moving unit for moving the substrate electrode part between a plasma-processing position in the processing chamber and a substrate-transferring position in the preliminary chamber, while keeping the substrate-mounting face generally horizontal; and a lid part provided in the preliminary chamber so as to be openable. Furthermore, the substrate electrode-moving unit of the plasma processing apparatus can move the substrate electrode part along the tilted direction between the plasma-processing position and the substrate-transferring position.

Playback apparatus, program, and playback method

Abstract: When playing an AV Clip recorded on a BD-ROM, a judgment is made, for each elementary stream, which of a plurality of predetermined conditions the elementary stream satisfies. The plurality of predetermined conditions include (a) a condition that a playback apparatus has a capability of playing the elementary stream, (b) a language attribute of the elementary stream matches a language setting of the playback apparatus, and (c) a channel attribute of the elementary stream is surround sound and the playback apparatus has a surround output capability. The playback apparatus assigns a priority to each elementary stream based on which conditions the elementary stream satisfies, selects an elementary stream having a highest priority, and plays the selected elementary stream.
