Title: Power supply
Inventor: YAMAMOTO KAZUMA
IPC: H02M3/28
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a power supply that is low-cost, that saves space and capable of reducing power consumption. SOLUTION: An FET 51 is a P-channel FET, and its source is connected to the cathode of a diode 16 and its drain to an electrolytic capacitor 20 respectively. By turning on a transistor 54 in accordance with a 24V-interrupting signal from an engine controller, a current is caused to flow into are a resistor 53, so that the FET 51 goes into a conducting state. Conversely, by turning off the transistor 54 in accordance with the 24V-interrupting signal, the current flow into the resistor 53 is shut, so that the FET 51 is put into a non-conducting state via a resistor 52. As a result, low-cost electrolytic capacitors can be used, because no excessive voltage is impressed on the electrolytic capacitors 20 and 35, at this interruption.

Filed: 1988-08-25
Abstract: PURPOSE:To obtain stable depth length by filling glass in a winding groove uniformly by forming both ends of a joining glass body with glass with a low m.p. CONSTITUTION:A melting glass body 14 in which a joined body whose both ends are formed with the glass with low m.p. and whose center with the glass with a high m.p. is heated and melted is filled uniformly in the winding groove 4 and a track width setting groove 7. Therefore, since the melted glass 14 is filled in the edge of the winding groove 4, no notch is generated at the edge of the groove 4 in a working process for an outer winding groove, etc. Thereby, depth length D can be set at a constant value and obtained stably. Also, in a joined glass body which becomes the melted glass 14, the floating of the glass is regulated by arranging a glass vapor-deposited film 18 with a softening point higher than that of the glass 17 with the low m.p. on both sides of the glass with the high m.p., and the glass 17 with the low m.p. is crimped then, heated and melted. A head can be obtained by cutting compound glass 19 in bar shape.

Title: Improvement of environment of water basin of hydrogen sulfide dissolution level
Inventor: INOUE SHOICHIRO
IPC: C02F1/58
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To remove or decrease the hydrogen sulfide and sulfide included in water and to prevent the consumption of a large quantity of dissolved oxygen in water by introducing a hydrogen sulfide-contg. water to a desulfurization vessel and precipitating sulfur particles from the hydrogen sulfide-contg. water by the effect of photosynthesis sulfur bacteria, thereby recovering the sulfur particles. SOLUTION: The water 1' of the water basin in which hydrogen sulfide is dissolved is supplied by a pump P3 to the desulfurization vessel 7 where the water is subjected to a photosynthesis by the effect of the sulfur bacteria to precipitate the dissolved sulfur and to recover the sulfur as the sulfur particles. The sunlight is condensed with high efficiency by a light collecting plate 8 in order to make the effect of the photosynthesis more effective. The light is introduced by an optical cable 9 to the part of the desulfurization vessel 7 where the sulfur parts are efficiently removed and recovered from the hydrogen sulfide-contg. water by using the photosynthesis sulfur bacteria. The treated water of the desulfurization vessel 7 where the sulfur particles are released via a suspended matter capturing vessel 6 is discharged to the original water basin.  As a result, the return of the precipitated sulfur in the form of hydrogen sulfide to the water basin by the reduction effect is prevented.

First, a sweep-starting- position signal is first received, an offset voltage which offsets the deviation is supplied to an analog addition means 50, and a gain value which becomes the inclination of a correction straight line is set simultaneously in a ramp-amplitude control means 40. Thereby, a sweep which is corrected to the correction straight line is performed to the section. In addition, a sweep which is corrected by a sweep finish oscillation frequency is performed by a similar means. Thereby, the oscillation characteristic curve of a voltage-controlled oscillator means 60 is corrected so as to be approximate to a straight line, and a frequency sweep which is nearly close to an ideal sweep characteristic is realized.

IPC: H03H9/17
Filed: 1986-09-10
Abstract: PURPOSE:To obtain a piezoelectric thin film resonator excellent in spurious characteristics and applicable to a VHF band/UHF band by forming a front face side piezoelectric thin film and a rear face side piezoelectric thin film whose polarizing directions are mutually different by 180 deg. through a front face side insulating layer formed on the front face of a semiconductor substrate and utilizing thickness longitudinal vibration to be the longitudinal effect of an even-order mode. CONSTITUTION:When the odd-order mode of thickness longitudinal vibration to be the longitudinal effect in the piezoelectric thin film resonator consisting of a composite thin film obtained by forming the front face side piezoelectric thin film 10 and the rear face side piezoelectric thin film 12 through the front face side insulating layer 2 is excited, the electrostatic charge of the thin film 10 is inverted from that of the thin film 12 as positive and negative charge. Since the polarizing direction 11 of the thin film is formed so as to be directed in the different direction from that 13 of the thin film 12 by 180 deg., the odd mode is attenuated and a secondary mode is gained. In case of unitlizing the secondary mode, the thickness of the layer 2 can be increased and the strength can be also increased as compared to the utilization of a primary mode. Thereby, the resonator can be applied to the UHF BAND having higher frequency in addition to the VHF band.
