Abstract: PURPOSE:To execute stable tracking by detecting the frequency components of 16kHz and 46kHz respectively by envelope detectors and controlling the gain of a voltage controlled gain variable amplifier with a voltage level obtained by adding respectively detected values. CONSTITUTION:An output of a switch 18 is applied to the voltage controlled gain variable amplifier 23 and the output of the amplifier 23 is outputted to a tracking error signal output terminal 20. On the other hand, 16kHz, 46kHz frequency components are envelope-detected by respective detectors 14, 15, the outputs of the detectors 14, 15 are applied to a subtractor 16 and an adder 21 and the output of the adder 21 is applied to the amplifier 23 as a control signal through an LPF 22. Although the output level of the adder 21 is a constant when a magnetic head 8 exists in the vicinity of the center of a video track, the level is increased in accordance with a shifted value from the center when the shifted value exceeds a fixed value. Thereby when the head exists in the vicinity of the center of the video track, stable tracking can be executed, and when the head 8 is shifted from the center by the fixed value or more, quick tracking lead-in is executed.

Title: Method for regulating flow rate and device therefor
Inventor: OSHITA AKIRA
IPC: C02F3/12
Filed: 1991-08-26
Abstract: PURPOSE:To regulate flow rate of the whole septic tank and to relax a peak in its turn by raising and lowering the water level in a biological reaction tank and controlling both transfer of sewage to a final liquid-solid separation tank from the biological reaction tank and transfer of sewage to the biological reaction tank from a flow rate regulation tank. CONSTITUTION:Air is slowly sent to an air chamber 1 provided to the inside of a biological reaction tank B by a blower 2. Circulating water in the biological reaction tank of the amount equal to the amount of the fed air is extruded from the air chamber 1. The water level in the biological reaction tank B is raised. The extruded circulating water is transferred to a final liquid-solid separation tank C in the downstream side. When an electromotive valve 4 for discharging air in the air chamber is opened by a time switch 3, the air is discharged from the inside of the air chamber 1 and this air chamber 1 is filled by the circulating water of the biological reaction tank. Simultaneously, the water level in the biological reaction tank B is lowered. A sewage transfer pump 5 in a flow rate regulation tank A is operated only for a set time by the time switch 3. Sewage is transferred to the biological reaction tank B from the flow rate regulation tank A. Therefore, the transfer amount of the biological reaction tank and the final liquid-solid separation tank are mutually equalized.

Title: Optical element and its production
Inventor: NASU SHOGO
IPC: G11B7/135
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To lower the dependence of light on an incident angle and to obtain good optical characteristics by alternately laminating highrefractive index films and dielectric films formed of specific compsn. materials on the substrate surface of an optical element, thereby forming polarization beam splitting films. SOLUTION: The polarization beam splitting films 4 are formed by alternately laminating the high-refractive index films consisting of the material Si1-a -Xa in which the compsn. (a) to silicon Si of X is 0.05<=a<=0.35 when X is defined as at least one material of oxygen O and carbon C and the dielectric films on the substrate surface of the optical element. As a result, the refractive index (n) is increased and the absorption coefft. is lowered and, therefore, the dependence of the incident angle on the angle is lessened and the variation in the characteristics of the high-refractive index film layers is suppressed. The phase difference between P polarized light and S polarized light is lessened as well.  The optical element is provided with reflection films 6 alternately laminated with the dielectric films having the lower refractive index than the refractive index of the high-refractive index films, by which the absorption coefft. is made smaller while the high refractive index (n) is maintained. The reflectivity is thus increased and the dependence on the angle is further improved.

Title: Optical semiconductor device
Inventor: NAO TAKASHI
IPC: H01S5/00
Filed: 1988-09-20
Abstract: PURPOSE:To obtain an optical semiconductor device with which the far-sight image characteristics of a signal beam can be improved by a method wherein a light emitting device and a spherical lens provided on the side to which the monitor beam of the light emitting device is emitted are housed in a container. CONSTITUTION:A monitor beam 8 emitted from a laser diode 2 and applied to a spherical lens 6 is condensed by the lens 6 and formed into a thin beam and applied to the light detecting plane 3a of a photodetector 3 and focused as a small light spot. As the reflected beam 8a of the focused monitor beam 8 is close to a reflected light from a point source, it is scattered radially to a wide range. Therefore, the application of the reflected beam 8a from the surface of the light detecting plane 3a to the light emitting layer 2b of the laser diode 2 is suppressed to be little. Moreover, as the main components of the monitor beam 8 are applied to the spherical surface of the lens 6 almost vertically, the reflected beam 8a of the monitor beam 8 reflected by the spherical surface of the lens 6 is hardly applied to the light emitting layer 2b. Therefore, the signal beam of the laser diode 2 can have excellent far-sight image characteristics.

IPC: C04B35/043
Filed: 1993-08-30
Abstract: PURPOSE:To obtain a refractory especially useful for fire brick of refining furnace and kiln or the like in contact with a basic molten body and a fired product containing a large quantity of iron oxide or the material of a reactor core tube or the like by allowing the refraction to consist assentially of magnesium oxide, and blending a specific oxide into them.

Titanium oxide, niobium oxide, neodymium oxide, lanthanum oxide, manganese oxide, nickel oxide or cobalt oxide is exemplified as the secondary component to be used. These compounds are usually blended by 0.1-50wt.% into the refractory. Since the refractory does not contain chromium oxide causing environmental pollution, special disposal is unnecessitated after use, so that it is advantageous from the viewpoint of environmental protection.

Title: Power supply, lighting device for discharge lamp and lighting equipment
Inventor: KAKIYA TSUTOMU
IPC: H02M7/48
Filed: 1994-09-30
Abstract: PURPOSE: To avoid overvoltage by controlling ON-OFF of a pair of switching circuits and by increasing the switching frequency of a pair of switching circuits in response to a rise in a first voltage at both ends. CONSTITUTION: When the output of oscillating means 13 is inverted, the switching circuit 5 is turned off and the switching circuit 6 begins to turn off. In this time period, a resonance circuit is formed from an inductor 7-capacitor 11-diode of switching circuit 6-inductor 7, and a resonance current flows to this circuit. Also, a voltage stepped-up by the resonance is generated. When a voltage across capacitors 8 and 11 rises, an output frequency of oscillating means 13 increases by the control means 15. Therefore, energy stored in the inductor 7 decreases. Because of this, step-up action is degraded or lost and an excessive voltage across the capacitor 8 can be prevented. By doing this, application of a high voltage to the switching circuit 5 and 6 can be prevented.
