Title: Magnetic bearing device for rotary body
Inventor: UEDA HIRONOBU
IPC: F16C32/00
Filed: 1990-11-26
Abstract: PURPOSE:To obtain stabilized high-speed rotation by installing an impeller for fluid compression/expansion at the end of a rotary shaft, disposing a controlling electromagnet at certain intervals in the axial direction of the rotary shaft, and regulating current and voltage of the electromagnet according to the oscillation frequency of a frequency converter for supplying power to a stator for the rotation. CONSTITUTION:A rotor 3 rotates by applying a specified frequency to a stator 4 of a driving motor from a frequency converter 9. As the rotational frequency rises, a pressure difference arises between the gas intake port of an impeller 1 and the interior of a bearing, so that the thrust in the axial direction increases. This axial thrust is borne by a thrust bearing 5. However, since a thrust bearing of the gas bearing type is small in load capacity stability in the high speed rotation region is not sufficient. To make up for this, the attraction force of the electromagnet 8 is increased with the rise of the rotational frequency corresponding to the oscillation frequency, so that the thrust load of the thrust bearing 5 is lowered under control.

Title: Cooperative decentralized type inference device
Inventor: MIYAMOTO SHINICHI
IPC: G06N5/04
Filed: 1989-12-08
Abstract: PURPOSE:To improve the reliability for the solution of problems by providing plural secondary problem solving parts and connecting these problem solving parts to each other in steps for cooperative solution of problems. CONSTITUTION:When a problem is inputted to the secondary problem solving part of the highest order, the problem solving part decides whether it can solve a due problem by itself or not. If so, the secondary problem solving part solves the problem by itself and sends this solution to a high-order secondary problem solving part. If not, the problem is decomposed into plural secondary problems via a problem decomposing part 46 and these secondary problems are sent to a low-order secondary problem solving part. This low-order problem solving part repeats the processing to the received secondary problems. When the problems are solved at the low-order problem solving parts, these solutions are sent back to a high-order problem solving part. Then plural solutions are synthesized at a result synthesizing part 47.

Abstract: PURPOSE:To reduce a slipperage of resonance frequency with deformation, etc., due to a facbrication tolerance or an external cause by making a second accelerating electrode to be freely moved in the axial direction and installing a movement adjusting mechanism for adjusting a void distance between the second accelerating electrode and a first accelerating electrode. CONSTITUTION:At a flange 13Bb of an accelerating electrode 13B, a movement adjusting mechanism is constituted such that the accelerating electrode 13B can be moved; for example, a plurality of setscrews 15 are threadedly engaged to each other and a lock nut 16 is threadedly engaged to each setscrew 15 and a flexible connector 17 is installed to electrically and vacuumly connect the external circumferential portion of the accelerating electrode 13B with the internal circumferential portion of a side plate 2A. Then, both ends of the flexible connector 17 are firmly sticked between the side plate 2A and the accelerating electrode 13B. It is thereby possible to absorb an amount of movement of the accelerating electrode 13B by a deflection (displacement) of the flexible connector 17 as a vacuum condition is left held even if the accelerating electrode 13B is moved in the axial direction, and sufficiently compensate a slipperage of resonance frequency caused by external conditions, fabrication tolerance, etc.

Title: Lighting device for high pressure discharge lamp
Inventor: MORISHITA TADAYUKI
IPC: H05B37/02
Filed: 1990-11-22
Abstract: PURPOSE:To rapidly raise light output in the initial lighting-on to the target rated value of the light output by having a neural network learned, with an input value and an output value considered as learning signals, so as to control the supply power or current to a high pressure discharge lamp. CONSTITUTION:The supply power or current from an AC power supply 1 in a high pressure discharge lamp 3 is varied by having a neural network 5 and 19 learned with an input value and an output value considered as learning signals. Namely, by inputting the illuminance of the lamp at the time-of-day t and the illuminance at the time-of-day DELTAt thereafter in the neural network which has finished the learning process, the signal to a programmable counter at the time-of-day t, required to arrive at the target illuminance, is calculated. Thus, the input/output characteristic of the lamp is converted into the quantity called the weight of the synapse so as to store it in a memory 23, so that the signal required to gain a certain illuminance, i.e., the inverse function of the input/output function, can be obtained. Consequently, in the initial lighting-on, a light output can be forced to rapidly reach the rated value without depending on characteristics of an individual lamp.
