Title: Driving circuit of angular velocity sensor
Inventor: ICHISE TOSHIHIKO
IPC: G01C19/5614
Filed: 1989-09-22
Abstract: PURPOSE:To enable prevention of a change in a zero point due to an angular velocity signal of a large amplitude by smoothing an output voltage of a phase detector and by inputting it then to an amplifier. CONSTITUTION:The amplitude of a voltage impressed on a drive element 101 is controlled by a first amplifier 1 amplifying a surface charge of a monitor element 102, a rectifier 2 rectifying a first output voltage, a smoothing circuit 3 smoothing an output voltage of the rectifier 2 and a second amplifier 4, and thereby the vibration of a tuning fork is turned to be definite. In the surface electrodes of first and second detecting elements 103 and 104, a charge is generated in accordance with an angular velocity impressed thereon, and amplified by a third amplifier 5. Next, it is phase-detected with a period of the vibration of the tuning fork by a phase detector 6 and turned into a voltage proportional to the angular velocity, and this voltage is DC-amplified by a DC amplifier 8 and outputted as an angular velocity voltage output. This output voltage and a ground voltage are inputted to and smoothed by a low-pass filter 10 and an output voltage thereof is made to be a plus input voltage of the amplifier 8. Thereby a zero point of the angular velocity voltage output is always made to be equal to the ground voltage.

Inventor: YAMASHITA KEITARO
IPC: G11B15/61
Filed: 1989-09-22
Abstract: PURPOSE:To reduce the variation of blowoff pressure corresponding to the number of grooves with a simple working method by forming a boundary between a spiral-shaped groove and a part other than the groove by nearly linear boundary lines with a first and a second angles, and determining each angle as it is prescribed.

Title: Signal transmission circuit by pulse transformer
Inventor: TSUDA MASANORI
IPC: H03K17/60
Filed: 1984-11-22
Abstract: PURPOSE:To prevent delay in signal propagation by connecting a + terminal of a DC power supply to a terminal of winding start of a pulse transformer primary winding via a switch and connecting a diode in the same polarity as that from the primary winding of the pulse transformer to the + terminal of the DC power supply. CONSTITUTION:In transmitting a high output signal H to a load circuit, switches S1, S2 are turned on/off alternately while a switch S3 is turned off. In giving a low output L, the switch S1 or S2 is turned off (with the switch S1 or S2 turned on) and the switch S3 is turned on. Since the switch S3 is turned on simultaneously, a short-circuit short-circuiting a PT primary winding is constitut ed in a path of PT primary winding - switch S3 - PT primary winding. Since the induced voltage by the residual magnetic flux of the pulse transformer PT is short-circuited by the said short-circuit, the voltage is lost in a very short time, the induced voltage due to the residual magnetic flux is not generat ed to the secondary winding of the pulse transformer and a low output signal L to the load circuit is transmitted without delay.

Title: Electrostatic actuator
Inventor: TAKAHASHI JUNICHI
IPC: H02N1/00
Filed: 1990-09-18
Abstract: PURPOSE:To eliminate the need of providing an actuator of a piezoelectric element, etc., to the outside so as to remarkably improve the productivity and reduce the weight of an electrostatic actuator by controlling the drive of a mobile section provided with a functional element by means of an electrostatic attracting force which acts between a low-resistance area formed on the end face of the mobile section and the low-resistance area of a fixed section facing the mobile section. CONSTITUTION:When a voltage is applied across the Va while the Vb is maintained at '0' in the figure, an electrostatic attracting force acts between low-resistance areas 18 and 19 and, because of the attracting force, a mobile section 15 moves in the direction P. On the other hand, when a voltage is applied across the Vb while the Va is maintained at '0', the section 15 moves in the direction Q. In addition, when voltages are respectively applied across the Va and Vb, with the value of one voltage being made larger than that of the other, the section 15 moves toward the larger-voltage applied side. Therefore, photographic images taken with a CCD 17 mounted on the mobile section 15 can be prevented from blurring or the CCD 17 can take high-resolution pictures when the section 15 is displaced in the direction P or Q.

Title: Vapor fuel treatment device for internal combustion engine
Inventor: KAWAMURA KATSUHIKO
IPC: F02M25/08
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of an unstable state of an engine which is caused by suctioning vapor fuel in a fuel tank into an intake pipe at the time of pressure reduction. SOLUTION: A vapor fuel treatment device of this type has a bypass valve 14, a purge control valve 11, and a drain cut valve 12. In order to determin leakage, the drain cut valve 12 is closed first and the purge control valve 11 is opened. Pressure is reduced inside the passage on the side of the intake pipe 8 from the bypass valve 14. After reducing the pressure inside the passage from the bypass valve 14 to the intake pipe 8 to a specified value, the purge control valve 11 is closed. Then the bypass valve 14 is opened. After passage of the specified time, pressure variation is measured in the passage from a fuel tank 1 to the purge control valve 11, for performing leakage diagnosis. It is thus possible to prevent the vapor fuel in the fuel tank 1 from being suctioned into the intake pipe 8, causting unstable state of the engine at the time of pressure reduction.
