Title: Bearing structure
Inventor: SHIMADO KOJI
IPC: F16C35/02
Filed: 1989-04-20
Abstract: PURPOSE:To smoothly rotate a rotary shaft of a bearing structure having a support structure in which a hole is formed, by shrinkage-fitting a ceramic bearing member having a thermal expansion coefficient lower than that of the support member into the inner surface of the hole in order to bear the rotary shaft by the ceramic bearing member. CONSTITUTION:In a bearing structure for rotatably supporting a rotary shaft 4, a support member 1 made of, for example, cast iron, has a bearing hole 2 having a circular cross-sectional shape. A bearing member 3 made of ceramic material such as silicon carbonate of the like having a low thermal expansion coefficient is shrinkage-fitted in the inner surface of the bearing hole 2. This bearing member 3 can rotatably bear the rotary shaft 4 made of a material having a thermal expansion coefficient substantially equal to that of the support member 1. As a result, a suitable clearance is held between the rotary shaft and the bearing member in a wide range from a lower temperature to a higher temperature, thereby it is possible to smoothly rotate the shaft.

Title: Parallel electronic computer system
Inventor: UMEDA YUJI
IPC: G06F9/50
Filed: 1989-04-21
Abstract: PURPOSE:To improve the performance of a parallel system by checking the presence/absence of another processor optimum for the distribution of a load when a new load occurs in its own processor based on load quantity information held by a control means, and making the optimum processor charge the new load when the optimum processor exists. CONSTITUTION:When the load occurs newly in a certain processor unit 10, the processor unit 10 judges whether or not the load is already heavy at a load movement judging part 2. The load movement judging part 2, when judging that the heavy load is already applied on its own processor 1, judges to which processor the optimum allocation can be performed based on information controlled by a load quantity control part 3. As a result, the load is allocated to the processor at a position where a load quantity is minimum. Thereby, since no time required for the allocation of the load is required, the processing performance of a parallel computer system can be improved.

Title: Motor drive controller
Inventor: OE KENJI
IPC: H02P6/182
Filed: 1994-05-17
Abstract: PURPOSE:To accurately generate an alarm signal at the time of decreasing the number of revolutions without unevenness of the detected number of revolutions due to the variation in a clamping voltage by comparing the charging lowest voltage of a charging circuit for charging in response to the rotating speed of a rotor with a reference voltage, and outputting the signal when it is lower than the reference voltage. CONSTITUTION:A comparator (CM) C01 forms a first detector for detecting the lowest charging voltage of a charging circuit. A CM C02 forms a second detector inputting a reference voltage provided by resistors R4 and R5 to a (+) input terminal to compare it with the lowest charging voltage input to a (-) input terminal and to output an alarm signal when the lowest voltage is lower than the reference voltage. When the rotating speed of a rotor is reduced, the OFF period of a transistor Q2 is lengthened, the charging/discharging period of a capacitor C1 is increased, and a charging lowest voltage V2 becomes lower than the reference voltage V3 of the CM C02. The output of the CM C02 becomes high, and an alarm signal is output.
