Title: Fault detecting system for sram
Inventor: YAMAMOTO TSUYOSHI
IPC: G06F12/16
Filed: 1989-12-20
Abstract: PURPOSE:To detect whether a fault occurs in a data store RAM or in a parity store RAM by storing in advance a parity of two bits. CONSTITUTION:A parity store means 5 receives a parity of one bit inputted from a parity generating circuit 2, and generates parity data of two bits. A parity deciding means 7 divides data of two bits of parity data 6 into data of one bit each and compares them, and when two one-bit data are different values, it is decided that a fault occurs in a parity write SRAM (static random access memory) 4. On the other hand, a parity checking means 9 generates a parity of read-out data 8, and decides whether it is the same value as parity data from the write SRAM 4 or not. Subsequently, an overall deciding means 10 executes a final decision of the SRAM fault. In such a way, whether the fault occurs in a data store SRAM 1 or in the parity write SRAM 4 can be detected.

Title: Re-utilizing system for acquired line
Inventor: MITSUBORI KOICHI
IPC: H04Q3/64
Filed: 1993-12-27
Abstract: PURPOSE:To reduce a wait time of a continuous call and to reduce a talking charge by utilizing a line used precedingly again as much as possible when other terminal equipment in the same area or in the vicinity of the area of an opposite terminal equipment for a first call is continuously called. CONSTITUTION:When a terminal equipment A requests re-utilization of a line and its call reaches a terminal equipment B via exchanges 1-1,2-1,2-2,1-2 by a 1st call, lines a, b, c, d are in holding by each exchange. When the talking between the terminal equipments A, B is finished and the terminal equipment A enters a number of a terminal equipment C of the exchange 1-3 as a destination of a succeeding call, the exchange 1-1 and the relay exchange 2-1 discriminate respectively the lines b, c as the lines connecting to the terminal equipment C to be used again and generate a command of utilizing the lines b, c again. However, the relay exchange 2-2 discriminates it that the line (d) is not available for the connection to the terminal equipment C. Thus, the exchange 2-2 commands the release of the line (d) to the exchange 1-2 to acquire a line (e) to which the exchange 1-3 connects.

Title: Tapered star coupler
Inventor: OKAMOTO KATSUNARI
IPC: G02B6/122
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a star coupler which is suitable for large-scale use and with which light can be uniformly distributed by contracting each core width of the input and output light guide passages in a gentle tapered form in a joint part between the input or output light guide passage and a slab light guide passage and in the vicinity. CONSTITUTION:Since the light inputted into an arbitrary input light guide passage 1 is not confined in the lateral direction with respect to the light advance direction in a slab light guide passage 4, the light spreads in the lateral direction. Since an input light guide passage array 8 and an output light guide passage array 9 arrange the guide passage in a sector form, the spread light is uniformly branched into an output light guide passage 5. In particular, at the joint part between the input light guide passage 1 or the output light guide passage 5 and a slab light guide passage 4 and in the vicinity, when each core width of the input light guide passage 1 and the output light guide passage 5 gently contracts in a tapered form, the light joint state between the guide passages can be controlled to an optimum state, and the uniformity of the light branching ratio can be improved, and the excessive loss can be reduced favorably. Accordingly, a star coupler which is suitable for a large-scale use can be obtained.

Title: Video recorder
Inventor: TAKEMORI HIROTOSHI
IPC: G11B11/105
Filed: 1988-12-27
Abstract: PURPOSE:To record and reproduce plural pieces of information in parallel by alternately recording and reproducing plural pieces of video and sound information simultaneously supplied on a magneto-optical disk at intervals of fine time in parallel. CONSTITUTION:Faint magnetic field H is previously impressed on the magneto-optical recording layer 56 of the magneto-optical disk 11 by a magnetic field generation source 57. When the desired area of the layer 56 with submicron order is irradiated with a laser beam 59a through an objective lens 58, the temperature of the irradiated part 56a rises and the magnetization is reversed. Thereafter, the direction of the magnetization of the part 56a is kept as it is even when the temperature lowers. In the case of erasing, it is good that the desired area is irradiated with the light beam 59a in a state where the magnetic field in an opposite direction to the magnetic field H is impressed. Reproducing is performed by a laser light beam 59b for reproducing whose plane of polarization is linearly polarized light. By radiating the magnetization to an upward part 56a, the linearly polarized light rotates clockwise and by radiating it to a downward part 56b, it rotates counterclockwise. The difference of the rotating direction is taken as the intensity of light by an analyzer 61 and is detected by a photodetector 62, thereby detecting the information on the layer 56. Thus, the plural pieces of information are alternately recorded and reproduced in parallel.
