Patent JP-H0612730-A (JP)
Title: Tape end detector
Inventor: TANAKA CHIHARU
IPC: G11B15/08
Filed: 1992-06-30
Abstract: PURPOSE:To reduce a power consumption by making the non-light emitting time of the light emitting section of a sensor near the tape end shorter than the time at the other portion or completely eliminating the non-light emitting time and making the non-light emitting time from the light emitting section longer at the other portion. CONSTITUTION:At the time of moving a tape at a recording or a reproducing or a rapid traverse of the tape, an approach to the end of the tape or the vicirity of the beginning of the tape are discriminated by the output pulses of photoreflectors PR6 or PR7. And prior to such an approach, the pulse emitting light of an LED3 controlled by a light emitting control means incorporated in a system controller 1 is controlled so that a non-light emitting time T off of pulses is made to a relatively longer value T2 to reduce the power consumption. When the tape is cut while the tape is running, phototransistors PTr4 and PTr5 are activated by the light emitting pulses of the LED 3, an on-signal is outputted and a tape cut is detected.

Title: Car parking brake automatic releaser
Inventor: YOSHIMI TOMOHISA
IPC: B60T7/12
Filed: 1980-12-09
Abstract: PURPOSE: To perform sure parking brake release and to prevent possible damage from leaving parking brake in effect by releasing parking brake automatically by means of release knob operating mechanism operated by amplified rotating torque of a DC motor driven by control signals.  
     CONSTITUTION: When all of an ignition switch, a brake switch and an accelerator switch are "on", a control circuit (not shown) generates a signal and passes it to DC motor 1. Rotating torque of DC motor 1 is amplified at gear box 2 and is converted from rotation to rectilinear motion at motion converter 4. Motion load thus produced at converter 4 pushes release knob 16 outward from center shaft 5 via final shaft 701 and clamp 702 of a release knob operator, to cause the parking brake to release. Then, current to DC motor 1 is cut and a small amount of current is supplied to DC motor 1 to conduct return process at low speed.

Filed: 1984-08-24
Abstract: PURPOSE:To enhance resolving power, by providing a pre-spectroscope in front of the main spectroscope of a spectrophotometer and by reflecting light by two concave surface diffraction gratings so as to turn back the same two times. CONSTITUTION:The light from a light source 1 or light source 2 is reflected by a light source mirror 3 to be condensed n an incident slit 21 and enters a pre- spectroscope 20. The light entering this pre-spectroscope 20 is dispersed and reflected by a concave surface diffraction gratint 19 to enter a main spectroscope 4 through an intermediate incident slit 5 and dispersed by the concave surface diffraction grating 6 being the duffusing element provided ina spectroscope 4 while the spectral image of this dispersed light is formed on the emitting slit 7 provided to said spectroscrope 4. Only the light, which passed through the aformentioned emitting slit in the light of which the spectral image was formed, is taken out as monochromatic light to enter a detector 14. As mentioned above, because light is reflected so as to be turned back only two times by the concave surface diffraction gratings 6, 19, the curving degree of a spectrum by aberration can be reduced.

Filed: 1991-07-16
Abstract: PURPOSE:To accurately determine the quality of welding by graphing motion of a stud at the time of pulling up the stud and welding it to base metal with pressure and subjecting this graphed curve to waveform analysis. CONSTITUTION:The motion of the stud is detected by a displacement detector and its signal is converted into an electric signal by a converter. This signal is inputted to a waveform analyzer and subjected to waveform analysis. These data are compared with determined reference data. This stud motion is graphed with the height direction as the axis of ordinates with the surface of the base metal as a reference point and with the time for pulling up, welding with pressure, etc., as the axis of abscissas. In this graphed curve, the height between the stud and the base metal, namely, the arc length and timing 14 when the stud is abutted on the base metal, namely, a molten state of a weld zone are important. Accordingly, this part 13 is analyzed and compared with the reference data and quality of welding can be determined.

Title: Optical disk driving apparatus
Inventor: HANANO MASAAKI
IPC: G11B7/085
Filed: 1995-07-11
Abstract: PURPOSE: To obtain an optical disk driving apparatus by which a precise access operation can be performed even when a disturbance such as a vibration, a shock or the like is applied to the apparatus. CONSTITUTION: Accelerometers 301, 302 are attached to both a head-actuator moving part and a fixation part. When outputs of both are made differential, the relative acceleration of the head-actuator moving part to the fixation part is detected. The relative acceleration is integrated so as to obtain a relative speed. The track transverse speed of a light spot is detected by both the relative speed and a speed signal which is obtained by differentiating a track transverse distance signal as the output of a track-transverse-distance detection circuit. Consequently, even when a disturbance is applied to an apparatus, the influence due to the disturbance of the head-actuator moving part can be detected precisely, and the influence of the disturbance can be suppressed.
