Title: Rotary electric machine for vehicle
Inventor: TAMURA SHIGEO
IPC: H02K15/02
Filed: 1987-06-19
Abstract: PURPOSE:To facilitate cleaning an apparatus while rotating a rotor by jetting compressed air to a rotor end face through a suction hole formed in a bearing box. CONSTITUTION:At the time of cleaning the inside of a motor, the blank cap 21 of in end connection 20 is drawn out, a hose 22 from a compressed air supplier such as compresser is connected with the end connection 20, and compressed air is fed into a blowing hole 15 via a communicating hole 19. Then, said compressed air flows from a blowing hole 15 into a flow dividing chamber 17, and further blows out from the flow dividing chamber 17 through each blowout hole 18 and jet hole 18a toward the end face and louver 2a of a rotor 2. Then, said rotor 2 having only the rolling resistance of a bearing 13 is simply rotated by compressed air coming out from a jet hole 18a inclined in a certain direction relative to the end face of said rotor 2. Therefore, compressed air blows out uniformly and circumferentially through said blowout hole 18 and jet hole 18a so that dust and the like having adhered to and accumulated on core pressers 10, 11 and a short-circuit ring 12 are caused to come off. In addition, dust accumulated on the inner peripheral face of the louver 2a is also separated and removed.

Title: Hydraulic control valve for duplex pipe structure
Inventor: KUBOTA HITOSHI
IPC: B60T8/26
Filed: 1979-11-28
Abstract: PURPOSE: To allow a couple of control valves to be contacted by springs even when these valves have manufacturing errors, by providing a tiltable spring seat for applying the forces of the springs to both of the valves, and retainers for receiving the spring seat in a titlted state.  
     CONSTITUTION: A spring seat 22 is provided such that it can be tilted to elastically support retainers 20, 20' and such that forces of springs 24 can be applied to a couple of control valves 8, 9 via the tiltable spring seat 22. Therefore, even when there is a difference between lengths h, h' due to manufacturing errors in the valves 8, 9, such a difference is absorbed by the tiltable spring seat 22. This allows the same forces of the springs 24 as are applied to the valves 8, 9 when the valves are in a normal condition, to be applied thereto constantly. As a result, hydraulic pressures which are applied to brakes for right and left rear wheels and which are individually controlled by the valves 8, 9 can be substantially equalized. Since itis  not necessary to increase the dimehsional precision, this valve certainly contributes  to the reduction of the manufacturing cost of hydraulic control valves.

Title: Magneto-optical disk device
Inventor: SAKURAI TATSUAKI
IPC: G11B11/105
Filed: 1987-06-19
Abstract: PURPOSE:To extend the life of a semiconductor laser by detecting heat generation of a magnetic head in a magneto-optical disk device and changing the quantity of light of the semiconductor laser and the intensity of the external magnetic field of the magnetic head in accordance with this detection. CONSTITUTION:In an example of erasing operation, a control circuit 9 first lights a semiconductor laser 4 with a set erasing power. The circuit 9 drives a magnetic head 2 through a magnetic head driver 7 so that the intensity of the external magnetic field is a prescribed value. When the head 2 generates heat because the erasing operation time is longer, the rise of temperature is detected by a temperature sensor 8. Then, the circuit 9 lowers the external magnetic field of the head and simultaneously strengthen the power of the laser 4. In such a way, while monitoring the heat generation state of the head 2, the power of the laser is controlled to a lower value, so the life of the laser is extended.

IPC: G11B7/13
Filed: 1984-07-24
Abstract: PURPOSE:To easily remove an amplitude noise through an electric circuit behind a photodetector by detecting a light signal by an avalanche photodiode during optical reproduction, detecting variation and feeding it back to a power source negatively, and controlling an operating bias to the avalanche photodiode. CONSTITUTION:A specific reverse bias voltage is impressed from a DC-DC converter 31 to the cathode of the avalanche photodiode 28 and an output signals corresponding to a light signal from the anode side is supplied to and amplified by a head amplifier 32. This amplified information signal is supplied to a limiter 33 to perform amplitude control, and part of the information signal is supplied to a DELTAP detector 34 to perform envelope detection, detecting variation of the information signal. This detection signal is fed back to the DC-DC converter 31 negatively through a smoothing circuit 35 and its output voltage, i.e. reverse bias voltage is controlled according to the variation. The avalanche photodiode 28 varies in amplification factor with the reverse bias voltage, so when the variation is large in amplitude, the amplification factor is decreased by lowering the reverse bias voltage and the level of the conversion output drops.

Title: Preparation of semiconductor device
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/68
Filed: 1993-06-24
Abstract: PURPOSE:To, after subjecting a wafer on a single-pole electrostatic chuck to plasma processing, prevent harmful effects on the result of the plasma processing in a subsequent residual electric charge removing process. CONSTITUTION:A Si material layer 19 is formed on the inside wall of the Al block chamber 4 in a magneto-microwave plasma etching system, and an elevating shutter 20 is installed inside the Si material layer 19. The F* content in ECR plasma P is controlled according to the area of contact between the Si material layer 19 and the plasma. A SiO2 layer insulating film is etched using fluorocarbon (FC) gas and then residual electric charge is removed. When O2 plasma is produced in the removal process, O2 decomposes the residue of FC gas and produces a large quantity of F*. To cope with this, the area of contact is increased to react F* with Si and consume it. This does not degrade the anisotropic shape or base selectivity of contact holes during the residual electric charge removing process.

Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To produce an easy-to-read and decent-looking document by calculating the character pitches to decide to perform the 'run-on' or 'run-off' processing. SOLUTION: At a preprocessing part (S1 to S4), a range of character pitches to be set in a Japanese hyphenation processing mode is decided. Then the length of character display width of a Japanese hyphenation object line is stored together with the total width of characters covering the first one through the final one within the line and the number of characters included in the line respectively. At a retrieval part (S5 to S8), the punctuation and the part of speech of the word that includes the final character are retrieved. If the final character shows a noun, the next part of speech is retrieved. If this part of speech is a postpositional word functioning as an auxiliary to a main word, 'a noun + the postpositional word' is recognized as a word.  At a Japanese hyphenation processing part (S9 to S10), it's decided whether a word is divided at the end of a line or at the head of the next line. If the word is divided, the Japanese. hyphenation processing is carried out to correct the character pitches and to display these characters. If the word is not divided, the relevant processing ends.
