Title: Speed reducer for electric motor
Inventor: IMAIZUMI KATSUMI
IPC: F16H1/02
Filed: 1979-09-28
Abstract: PURPOSE: To enable the ratio of speed reduction through only the exchange of the first stage gear, by placing the axis of a motor pinion uncoincidently to the center of a gear case socket-and-spigot fitting means provided in an electric motor.  
     CONSTITUTION: In application to a one-step speed reducer for an electric motor, the first stage gear is removably secured on an output shaft 5 so that the gear is engaged with a motor pinion 2. A gear case 4 and a motor bracket 3 are fitted on each other by a socket-and-spigot fitting means and positioned by a knocked-in pin. The axis 16 of a motor spindle and the center 14 of the fitting means are placed at a distance of (e) from each other. The axis 15 of the gear 9 and the center 14 of the fitting means are placed at a distance of (c) from each other. The distance of (a) between the axes of the pinion 2 and the gear 9 varies according as the gear case 4 is rotated along the fitting means. For that reason, the case 4 is rotated to move the pin 6 to positions AWC to engage the pinion 2 with the prescribed gear 9. The ratio of speed reduction can thus be changed.

IPC: B62D5/22
Filed: 1984-06-16
Abstract: PURPOSE:To improve the responsiveness for generating the steering auxiliary force by switching oil paths via the rotation of a spool as well as the axial shift of the spool. CONSTITUTION:When a spool 6 is rotated by a step motor, two pairs of notches 30, 31 and 34, 35 are displaced in the peripheral direction, no overlap sections are left, and the transit of the operating oil is cut off. At the same time, overlap sections of other two pairs of notches 32, 33 and 36, 37 are further increased. Accordingly, a pump port P and a right port R, and a left port L and a drain port D are communicated to each other, a power cylinder is driven to shift a rack shaft leftward, and a steering auxiliary force can be obtained. When the steering speed of a steering wheel is high, the spool 6 is thus rotated then is shifted in the axial direction.

Title: Reluctance motor
Inventor: BAN ITSUKI
IPC: H02P6/28
Filed: 1988-05-23
Abstract: PURPOSE:To suppress mechanical vibration and noise, by differentiating the air gap length between a magnetic pole and a salient pole in a semi-circular face from that in the other semi-circular face. CONSTITUTION:Dotted line 4 represents the locus of the salient pole face of a rotor 1 rotatable through a rotary shaft 8 while a dotted line 3 represents a circle along the magnetic pole face of an armature core 16 and dotted lines 2a, 2b represent the central positions of magnetic poles 16a, 16b. The length of gap between the magnetic pole and the salient pole is approximately 0.1mm and unbalanced residual force causes radial reciprocation of the rotor 1 and produces random pressure for inducing vibration. In order to suppress the vibration, the height of the magnetic pole face at the positions shown by the dotted lines 2a-2d is differentiated from that at the positions shown by dotted lines 2e-2h thus differentiating the length of gap. In other word, the length of gaps 5a, 5b is made shorter than the length of gaps 6a, 6b with the difference being set to about 20mu. Since the rotor 1 is continuously subjected to attraction in the direction shown by a dotted arrow 5b, and the direction of the attracting force scarcely changes, vibration can be prevented.

Title: Gas detection method
Inventor: YOSHIKAWA MITSUO
IPC: G01N21/27
Filed: 1979-09-26
Abstract: PURPOSE:To enable a device to detect and measure gas in a wide area only by itself alone, by branching out light from a single light source in such a manner that light passages are different from one another, and by converting varation in the light passages electrically. CONSTITUTION:A pulse light radiated from a laser 9 is divided into 2 parts by No.1 mirror 11 which is a semitransparent mirror provided on the top of tanks 1 through 8, and one of the beams travels in such an order as No.2 mirror 12, No.3 mirror 13 and No.4 mirror 14 and it returns to No.5 mirror 15 and then enters a detector 10. And the other beam travels in such an order as No.6 mirror 16 No.7 mirror 17, No.8 mirror 18 and enters the detector 10 after passing through the No.5 mirror 15. Since these two light passages are different from each other in length, time of their entering the detector 10 also become different from each other accordingly, and this establishes a relationship of DELTAt=(l2-l1)/c (where c is light velocity). Therefore, if outputs of the two detectors are appropriately treated by a signal treatment circuit 19, it is possible to detect gas leakage in the light passage from difference in wave light values of all signals.

Title: Controller
Inventor: MASUDA SHIYUNICHI
IPC: G05B9/02
Filed: 1984-06-18
Abstract: PURPOSE:To attain a safe operation of a controller by supplying a clock from another oscillator when the actuation of a clock pulse source is detected and a fault signal is detected. CONSTITUTION:A disk 1 starts its revolution as soon as a photosensitive drum 6 starts its revolution with generation of a main motor drive/high voltage transformer actuation signal. Then a clock pulse generator 3 produces clock pulses. This clock pulse signal is impressed to a microprocessor concurrently with revolution of the drum 6. If this drum clock has a fault, a signal NG is changed to a low level from a high level. Then the output of an AND gate (e) is kept at a low level, and the input of an AND gate (c) is turned to a high level by an inverting circuit (b) and delivers the signal of an oscillator (a). Therefore the signal of the oscillator (a) is impressed to the processor by the signal NG via gates (c) and (d). Thus the processor executes its prescribed processing.
