Patent JP-S6290914-A (JP)
Title: Electronic component
Inventor: TAMURA TOYO
IPC: H01L23/28
Filed: 1985-10-17
Abstract: PURPOSE:To eliminate an outside expansion of the opening side of an insulating case even when a deflection is produced at the opening side of the case by providing a bent portion bent toward the inside from both ends of the side at the center of the arbitrary side of a bottom plate combined with the case. CONSTITUTION:The opening side of an insulating case 14 tends to deflect toward the inside. The prescribed bent is formed at each side of a bottom plate 16 to the opening side tending to bent toward the inside. The opening side of the case 14 which is formed by the deflection does not disturb the bending force toward the inside but deflects toward the inside. A gap is eliminated between the plate 16 and the opening side of the case 14. Since the opening side of the case 14 is deflected toward the inside, the opening side does not extend from both ends of each side. Thus, when the arbitrary inside of the bottom plate is bent, the deflecting force of the case 14 can be absorbed by the bent portion formed at the bottom plate.

Title: Vibration measuring device for sheet-like object
Inventor: KISHI TADASHI
IPC: G01N29/00
Filed: 1989-09-07
Abstract: PURPOSE:To exactly measure a general characteristic of a sheet-like object by allowing a laser light to be made incident on one point B of the surface of the sheet-like object at an arbitrary angle from the X - Z directions, and giving vibration to the point B through the sheet-like object. CONSTITUTION:A pulse signal is outputted to a vibrator 19 from a power source 17, and time t1 of that time is inputted to a time measuring device 20. An ultra sonic wave from the vibrator 19 is propagated through a sheet 16 and reaches a point B, and by this vibration, a laser light 5 receives a Doppler shift. The Doppler shift is converted 3 to an electric signal, and time T2 of that time is inputted. t2 - t1 is regarded as a propagation speed of an ultrasonic signal propagated in the sheet 16. The Doppler shift occurs only in beams 8 (7) which are made incident from the Y (X) directions against the sheet 16 through mirrors 13 (12) in the longitudinal (transverse) waves, and in the wave vertical to the sheet surface, the Doppler shift is large by a beam 9 which is made incident from the Z direction through a mirror 11. Accordingly, by checking which direc tion Doppler shift is large, the vibration direction of the ultrasonic wave is known.

Title: Image forming device
Inventor: MARUYAMA SHOJI
IPC: G03G21/00
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To discriminate between a motor failure and a load abnormality. SOLUTION: When the operation of a current limiter 713 is confirmed and the rotation of a motor 703 is detected, it is recognized that the motor tries to rotate, but a load is heavy, so that it is judged that the load is abnormal and a status with respect to a host is prepared/transmitted. On the other hand, when the current limiter is not operated, it is recognized that a current is not supplied to the motor, so that it is judged that a motor unit has any failure and the status is prepared/transmitted. Thus, the modes of the motor failure and a load abnormality are separated by using the current limiter 713 and a motor rotation signal, to urge a user to attain a proper abnormality processing.

Title: Timing circuit
Inventor: HARADA TAKU
IPC: H04L7/027
Filed: 1987-09-18
Abstract: PURPOSE:To obtain clock phase change characteristics free from resonance by making the time constant of an offset correcting circuit of a limit amplifier sufficiently shorter than the response time of the phase change of timing. CONSTITUTION:A timing component different by the pattern of a received digital signal is included in this digital signal. When this timing component is changed stepwise, the magnitude of the timing wave of the output of a timing detecting circuit 4 indicates the extension of the response time. Therefore, the time constant of an offset correcting circuit 51 is made sufficiently shorter than the response time of the timing extracting circuit 4 by an offset correcting time constant control capacitor 53. As the result, the good clock phase change characteristics free from resonance are obtained because its offset is always controlled on the way of the phase change with respect to offset correction.
