Patent JP-H0346809-A (JP)
Title: Piezoelectric oscillator
Inventor: SETO HIROSHI
IPC: H03H9/17
Filed: 1989-07-14
Abstract: PURPOSE:To prevent positional deviation or dropping of a lead terminal from a piezoelectric substrate and to improve the work efficiency by forming a U-shaped attaching part made of a shape memory alloy in the front end part of the lead terminal of an electrode formed for the surface of the piezoelectric substrate to pinch the electrode part of the piezoelectric substrate. CONSTITUTION:A shape memory alloy 16 is stuck to the front end part of a lead terminal 12, and this shape memory alloy 16 is caused to memorize the U shape which has first gap dimensions l1 equal to or smaller than a thickness L of a piezoelectric substrate 11. At a normal temperature, the lead terminal 12 is opened to extend gap dimensions of a U-shaped attaching part 15 to second gap dimensions l2 wider than the first gap dimensions l1. The piezoelectric substrate 11 is set to the attaching part 15 of the lead terminal 12. When they are heated at a high temperature in such a state, the substrate 11 is pinched by the U-shaped attaching part 15 because the shape memory alloy 16 is returned to the original state, and an output electrode and the lead terminal 12 are joined.

Title: Sample vessel for x-ray microscope
Inventor: MOCHIMARU SHOICHIRO
IPC: G01N1/28
Filed: 1993-07-23
Abstract: PURPOSE:To capture an observation object in a narrow view field of an X-ray microscope for a long time by holding the observation sample in water film self-held by surface tension. CONSTITUTION:On a silicon base plate 1, a diamond thin film 2 is formed in layer and in the center part of the base plate 1, an opening 1a for incidence or emission window is formed by anisotropic etching. A containing space 4 is formed by connecting a spacer 3 and mesh part 5 of nickel element wire is arranged. Thus, by dropping water solution on the mesh part 5, a water film 6 self-held by the surface tension is formed. By making the water film hold a bio-sample 7, the diamond thin film 2 surface of the other constituting body is similarly coupled to the spacer 3 to seal as a whole. As the results, the movement of the bio-sample 7 being an observation object is restricted in the sample vessel constituted like this, and so the observation becomes very easy.

Title: Regenerative brake control circuit for electric vehicle
Inventor: YAMADA YOSHIMITSU
IPC: B60L7/12
Filed: 1988-07-22
Abstract: PURPOSE:To brake an electric vehicle smoothly under high speed travel or low speed travel by decreasing the duty ratio of control pulse when a DC motor is rotating with high speed or low speed. CONSTITUTION:A one-shot multivibrator 5 provides a control pulse P7 having constant duty ratio to a drive transistor 7 corresponding to the current flowing through a DC motor 1 which is detected through a shunt resistor 2. The output voltage from an operational amplifier 24 is high when the speed signal is low and decreases in inverse proportion to the intensity of the speed signal. The output voltage from an operational amplifier 25 is constant when the speed signal is low and increases in proportion to the magnitude of the speed signal. Consequently, the discharge time of a capacitor 55 in the one-shot multivibrator 5 varies when the speed signal is low or high thus decreasing the duty ratio of the control pulse P7.

Title: Apparatus for detecting rotational speed of rotary body
Inventor: NAKAHARA KAZUHITO
IPC: G01P3/42
Filed: 1986-08-06
Abstract: PURPOSE:To detect rotational speed with high accuracy, by applying time differentiation to a detected angle obtained by operating the number of cycles and phase of a synchronous signal. CONSTITUTION:A comparator (Cp)2a inputs the cosine wave from a cycle signal generator 1 to compare the level thereof with a zero level to output an A-signal. A comparator (Cp)2b inputs a sine wave to output a B-signal. The A-signal and the B-signal are inputted to an angle range output apparatus 3 to output a count value thetal and the cosine wave from the generator 1 is inputted to a signal selector 5a through a polarity reversal device 4a. The sine wave is also inputted to a signal selector 5b through a polarity reversal device 4b. The selector 5a allows the cosine wave directly inputted from the generator 1 and the polarity reversal signal through the reversal device 4a to correspond to the level of the B-signal and outputs a homopolar signal when high while outputs a heteropolar signal when low as a Ca-signal. The selector 5b also outputs a Cb-signal similarly. Both of the Ca-signal and the Cb-signal are subjected to subtraction and A/D conversion to output a signal thetas which is, in turn, added to the signal thetal to output a thetaSIGMA signal while time differentiation is applied to said thetaSIGMA signal by a differentiator 9 to obtain a rotational speed. As a result, the enhancement of detection accuracy is achieved.

Abstract: PURPOSE:To improve the response of a gain control circuit, by providing a comparison circuit activated through the detection of an output of an amplifier circuit, increasing the charge or discharge current to a capacitor, and controlling the gain of the said amplifier circuit. CONSTITUTION:A video signal applied to an input terminal 1 of a television (TV) receiver is given to an output terminal 3 via an amplifier circuit 2 controlling the gain.

A differential circuit comprising TRs 28, 29 is set within the dynamic range only when the differential circuit comprising the TRs 13, 14 is within the dynamic range, to increase the charge/discharge current to the C9. Thus, the response of the gain control circuit can be improved.
