Title: Immersion type water gauge
Inventor: KASAI SHOZO
IPC: G01F23/18
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide an immersion type water gauge with improved reliability by maintaining its sealability over a long period regardless of water depth. SOLUTION: In an immersion type water gauge, the outside diameter of an upper lid 12 is smaller than the inside diameter of a water pressure resistant case 8. A plurality of claws 35 are attached to the upper lid 12 and inserted into grooves 36 formed on the inner periphery of the water pressure resistant case 8. Because the thickness of the claw 35 is smaller than the width of the groove 36, the upper lid 12 moves vertically within the water pressure resistant case 8 as water pressure varies. A seal is doubly formed. As water depth varies, the force of the upper lid 12 to clamp O-rings 13, 13' varies, and a sealing force is varied by the self-tightening action of rubber as water depth varies. Therefore, sealability is maintained over a long period regardless of water depth.

Title: Power amplifier
Inventor: KASHIWA HIDEAKI

Filed: 1988-12-19
Abstract: PURPOSE:To generate a pulse width modulation signal with excellent linearity by providing a control circuit controlling the amplitude of a triangle wave carrier signal output from a triangle wave generating circuit and a power voltage fed to an output amplifier in response to the amplitude of an analog signal. CONSTITUTION:The amplitude of a triangle wave carrier signal generated from a triangle wave generating circuit 3 is controlled with a control signal outputted from a control circuit 10. In terms of the triangle wave carrier signal, in spite of the amplitude change of an analog signal, the control signal controls the amplitude of the triangle wave carrier signal so as to always compare the triangle wave carrier signal with a modulation signal in a region of excellent characteristic. Then the modulation signal and the triangle wave carrier signal inputted to the comparator circuit 4 are compared in the comparator circuit 4, from which a pulse width modulation signal is outputted in response to the analog signal. Since the pulse width modulation signal is generated by comparing the triangle wave carrier signal with the modulation signal at a region with an excellent linearly of the triangle wave carrier signal, an ideal pulse width modulation signal without distortion is obtained.

Title: Speed motor detector
Inventor: AIHARA TAKASHI
IPC: G01P3/489
Filed: 1989-12-08
Abstract: PURPOSE:To form an accurate control system by setting the value based on the output of a frequency detector to a speed detection value when a motor is operated at a high speed and changing over the same at the time of the low speed operation of the motor so as to set the output of a pulse generator to a speed detection value. CONSTITUTION:For example, the interval of a quadruple pulse is always monitored by a change-over judging apparatus 4 and, since a motor M is rotated at a high speed when said pulse interval is short, a switch 5 is changed over to a frequency detection means to obtain a speed detection value. Since the motor M is rotated at a low sped when the pulse interval is long, the switch 5 is changed over to a pulse generating means 3 to output a pulse as a speed detection value. By this method, detection reduced in detection delay can be performed even in the low speed region of the motor M and the speed control characteristic of the motor M can be enhanced.
