CONSTITUTION: A plurality of grooves or recessed parts 11 are formed in the central part of a sheetlike vibrating body 1 so as to be easily deformed. One each, i.e., total of four detection electrodes 5 are formed on the rear surface of a sheetlike piezoelectric element 2 inside a support member 10 in the positive direction and the negative direction on X-axis and Y-axis which crass at right angles in the center of the rear surface, and a circular part is left in the center so as to be a concentric circle shape. Feedback electrodes 4 are formed inside the member 10 and in the circular part in the center. An electrode is formed on the surface of the element 2, and an electrode 7 and an exciting electrode 8 are formed respectively on the rear surface and the surface of the piezoelectric element 2. Since the electrodes 4 are formed in the central part of the element 2 and outside the member 10 in this manner, a vibration becomes stable. Since the electrodes 5 are formed inside the member 10, an angular velocity can be detected with good efficiency by the small electrodes 5.

Abstract: PROBLEM TO BE SOLVED: To reduce an error cause due to a change in a delay time and to realize accurately measuring by measuring a delay time generated by a delay time generating means by a delay time measuring means. SOLUTION: An ultrasonic signal oscillated from a first vibrator 2 according to a burst signal from a transmitter 4 is propagated through a flow of a channel 1, sensed by a second vibrator 3, a delay time generated from a delay time generating means 9 is placed, and then the burst signal is again transmitted from the transmitting circuit 4. The signal from the transmitting circuit 4 is repeated predetermined number of times, and a time required for the repetition is measured by an accumulation time measuring means 12, and the delay time is measured by a delay time measuring means 10. The delay time obtained by the means 10 is subtracted from a value obtained by the means 12 in a flow rate operating means 8 to obtain a predetermined time T only for the transmission of the ultrasonic wave.  To actually measure the delay time, even if a change cause occurs, the time T can be accurately obtained.

Abstract: PURPOSE:To obtain a suitable charging amount without excessive or insufficient charge by controlling the charge of a storage battery on the basis of the detected value of the output voltage of a differentiator for obtaining a differentiated value for the timing change of the terminal voltage of the battery. CONSTITUTION:When a start pulse generated at the time of turning ON a power source of a charging circuit is applied to the set terminal S of an FF 11, an output terminal Q becomes a high level, and a charge controller 2 becomes a quickly charging state.

Since the output terminal Q of the FF 11 becomes a low level in the reset state, the controller 2 becomes a charge control state to stop charging of the battery 1 or to reduce charging current.

Title: Optical recording medium
Inventor: MATSUI TSUTOMU
IPC: B41M5/26
Filed: 1981-06-25
Abstract: PURPOSE:To prevent the dispersion of heat in the reproduction time and to increase the access rate, by forming previously plural tracks on a single surface of a disk substrate and providing a metallic reflecting film on the upper wall of the track except both side faces and on a single surface of the substrate. CONSTITUTION:Plural tracks 11 are previously formed concentrically or spirally on a single surface of a disk 12 using a transparent substrate 8. Then a metallic reflecting film 9 is vapor-deposited on a single surface of substrate 8 and on the  upper wall 11b of the track 11. In this case, the film 9 does not stick to both  side faces 11a of the track 11. Using such a disk, light beams are irradiated concentrically on the track 11 through an objective lens 7 to reproduce recorded information. A thermally insulated part is formed at both side walls 11a of the track since no film 9 exists there. As a result, the dispersion of heat is prevented in the radius direction of the disk, and the increase of temperature 14 is large. Thus the threshold value is attained in a short time to increase an access rate.

Filed: 1987-04-22
Abstract: PURPOSE:To provide a differentiation (pulse generating) circuit simply with a very small area in a semiconductor integrated circuit by controlling the bias voltage of an output voltage control transistor(TR) at the edge of an input pulse voltage. CONSTITUTION:Applying a square pulse with an amplitude of 0-5V from an input terminal 3 in a state of a power voltage of 3V is being applied from a power supply 1, a TR 7 is turned on and the emitter and collector voltage is lowered by a nearly forward voltage of a diode and reaches about 4.3V. In such a case, a TR 6 is reverse-biased because the emitter voltage is 3V, the output is pulled up by a resistor 5 and the voltage at an output terminal 4 is 3V. When the input pulse starts descending and reaches 3V or below, the TR 6 is turned on, the output voltage is lowered rapidly, and when the level of the input pulse reaches 0.7V or below, the TRs 6, 7 are turned off and the output goes to 3V. Thus, a differentiation pulse is obtained at the output terminal 4.

Abstract: PURPOSE:To improve voltage waveform to be applied on a load, and to realize the excellent voltage waveform with a flat part by connecting a waveform correcting capacitor in parallel with a square wave generator between the output terminal of the square wave generator and a saturation reactor. CONSTITUTION:A pulse power supply 1 and the square wave generator 2 are connected, and the load 5 is connected to the output side of them through the saturation reactor 3 and a circuit inductance 4.
