Title: Device for controlling stopping of a.c. induction motor in machine tool
Inventor: NOMURA HIDEKI
IPC: H02P3/24
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a device for controlling stopping of an a.c. induction motor in a machine tool, which can satisfactorily prevent erroneous operation due to superposition of noise and which carries out satisfactory motion. SOLUTION: Until 340 ms elapses from an initiation of brake operation, signals which disable a rise-up of a phase detection signal for 300 μs are simultaneously delivered to terminals CW, CCW (brake initiating output), and then, a brake initiating output which disables the rise-up for 600 μs is generated, and is stopped after 400 ms elapses from the initiation of the brake operation. The brake initiation output is stopped after 400 ms elapses from the initiation of the brake operation. At the initial stage of the brake operation, since the brake initiation output is generated on the basis of a signal having passed through a relatively small first filter, a satisfactory braking force can be obtained.  Further, at the final stage of the brake operation, the brake initiation output is generated being based upon a signal having passed through a relatively, large second filter, and accordingly, the superposition of noises can be surely prevented, thereby it is possible to enhance the stopping accuracy of the motor.

Title: Suspension for vehicle
Inventor: ORIMOTO YUKIHIRO
IPC: B60G3/20
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the undesirable movement of a car body at sudden braking or sudden starting while keeping riding quality. SOLUTION: This suspension supports a knuckle 26 and a wheel W on a subframe 5, and supports the front end and the rear end of the subframe 5 on a main frame 6 through a front cylinder 7 and a rear cylinder 8 which are placed vertically, respectively. When the front cylinder 7 is contracted and driven, and the rear cylinder 8 is expanded and driven, the subframe 5 tilts to the rear and a locus angle of inclination which is an angle to be made by a moving locus of the center of the wheel W and road surface slope viewed from the side of a car body increases, accordingly, the shock to be input into the wheel W from irregularity on road surface is absorbed, which heightens riding quality.  In contrast with this, when the locus angle of inclination is decreased, the undesirable movement of a car body to be caused by inertial force acting in the front and the rear direction of the car body at sudden braking or sudden starting of a car can be prevented.

In such way, the integral value of the using sheet number of each department that is subjected to a coefficient process is stored in the parts M0-Mn at a department storing part of a storage device 10. And the cumulative number of using sheets for each paper size is stored in the regions MX-MZ at the paper-based storing part and then displayed at a display 28.

Title: Optical module protection circuit
Inventor: SATO YASUO
IPC: G02B27/00
Filed: 1988-01-29
Abstract: PURPOSE:To set up the temperature of an optical module within a holding temperature range even if a main power supply is turned off in a high/low temperature state and to prevent the optical module from being deteriorated by receiving the power of a stand-by power supply to be driven by the input of a main power supply off detecting signal and controlling the drive of a Peltier driving circuit. CONSTITUTION:When the main power supply 1 is turned off by an accident, a temperature control circuit 4 is disabled. An off detecting circuit 5 detects power supply off and outputs an off detecting signal from its terminal 5a and the stand-by power supply 6 is driven by inputting the off detecting signal from its terminal 6a and supplies power to a protection circuit 7 from its terminal 6b. Since power is supplied from the stand-by power supply 6 to a terminal 7a of the circuit 7 and a 'HIGH' temperature detecting signal is inputted from its terminal 7b, a current turn-on signal for allowing Peltier current to flow into a Peltier element is outputted from its terminal 7c. Consequently, the temperature of the optical module can be dropped and controlled within the holding temperature range. When the main power supply 1 is turned off in the low temperature state of the optical module, said operation is reversed.

Abstract: PURPOSE:To separate a transmission/reception light by a polarized beam splitter with almost no loss by providing a laser line rotating device having a lambda/2 wavelength plate correcting the polarized direction of a transmission/reception laser beam made incident/emitted into/from an optical antenna section. CONSTITUTION:A transmission light 21 is emitted from an optical transmitter 2, passes through a laser line rotating device 1 through a beam splitter 12 and emitted via a mirror angle drive mechanism 9 and an optical antenna section 11. Moreover, a received light 22 is made incident to the rotating device 1 via an optical antenna section 11 and the mechanism 9 and the direction of polarization is corrected in the rotating device 1 so as to be orthogonal to the polarization direction of the light 21. Then the corrected reception light is reflected in the splitter 12, branched by a beam splitter 13 and made incident in a transmitter/receiver 3 or the like. In this case, a lambda/2 wavelength plate 8 of the rotating device 1 is driven by a motor or the like and the polarized direction of the beam is set optionally, then the transmission light orthogonal to the received light sent from an opposite station is emitted to the opposite station. Thus, the separation of the transmission/reception light is attained by the polarized beam splitter with almost no loss.
