IPC: H03M13/00
Filed: 1986-12-26
Abstract: PURPOSE:To miniaturize the size of hardware and to attain large scale circuit integration by connecting plural number of identical arithmetic circuits each comprising a multiplier on a Galois field, an adder, and m-stage of register arrays storing its addition output and a selector output so as to generate a specific syndrome from a specific received word. CONSTITUTION:The repetitive algorithm in equation I is used to calculate coefficients of a syndrome polynomial. In case of i=1 at first, the relation of S1, S2=10 exists as to selection signals S1,2 of the selector only when a reception symbol rn-1 is inputted and 0 being a C input is outputted from X output and Z1=rn-1 is inputted sequentially to 2t-stage of registers. In selecting S1, 2=00 thereafter, the X output of the selector selects the A input, Zi-1 being the result of preceding arithmetic operation is outputted sequentially from the X output and given to the register. Thus, the registers of 2t-stage reserve tentatively the midway result of the arithmetic operation of Si-1(j-1,...,2t) and feeds it back again as the memory section. Thus, the processing of 2t-set of processing elements PE is realized by one PE.

Title: Electromagnetic brake gear
Inventor: SHIMAZAKI TOSHIO
IPC: B66B11/08
Filed: 1987-12-10
Abstract: PURPOSE: To provide an inexpensive, highly reliable and easily adjustable brake operation detecting device by arranging a reflecting plate on a lever, and detecting brake operation by receiving the light by the light receiving part by reflecting the light from the light projecting part of a photoelectric switch by this reflecting plate. CONSTITUTION: When a plunger 13 is displaced, since a reflecting plate 32 also rotates together with a lever 18, the light emitted from the light projecting part 34 is reflected by this reflecting plate 32 to be received by the light receiving part 35 so as to detect operation of a brake. Therefore, since a change in an angle formed by the incident light and the reflected light can be enlarged more than a turning angle of the lever 18, slight displacement of the plunger 13 can be accurately detected. Therefore, brake operation can be accurately detected by the minumum part constitution. Since there is no mechanical contact part in a brake operation detecting device itself, there is no fear of a secular change, so that an easily adjustable, inexpensive and highly reliable brake operation detecting device can be provided.

In this way, the developed stress is not acted to the tip part of arm body A, and also scarcely acted to the foot part C1 of chip C and not remained. Therefore, the cracking of the chip C caused by shrinkage stress are prevented.

Title: Information recording and erasing
Inventor: KOBAYASHI TADASHI
IPC: B41M5/26
Filed: 1989-11-30
Abstract: PURPOSE:To stabilize recorded information by generating a change in crystal grains by irradiation of a recording layer with a light beam, thereby recording and erasing the information. CONSTITUTION:A protective layer 3, the recording layer 2, the protective layer 4 and a protective layer 5 are formed in this order on a substrate 1. The recording layer 2 is formed of the material, the crystal grains of which attain different states when irradiated with the light beam and vary in optical characteristics between the respective states. Since the recording layer 2 is usually amorphous in the state of forming the film, the recording layer is initially crystallized by heating and slowly cooling the layer by irradiation with the light beam. The recording layer 2 initially crystallized in such a manner is irradiated with the light beams of different conditions and is reversibly changed in phases between the two different crystals of the crystal grains, by which the information is recorded and erased. As both the recording state and the erasing state are crystals in this way, the recorded information is stabilized.
