IPC: H05B41/24
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent a voltage across both terminals of a smoothing capacitor from increasing abnormally, for example, if a dimmer lamp is on when an input current distortion is reduced by a simple circuit configuration and at the same time the oscillation frequency of an inverter circuit is increased. SOLUTION: A pulsive current Id is allowed to flow from a rectifier DB at a high frequency, and input current harmonic distortion is reduced and power factor is improved with a simple circuit configuration according to the relationship among three voltages of a voltage Vc4 across the terminals of a capacitor C4, a voltage Vdc across the terminals of a smoothing capacitor C1, and a pulsation current DC voltage Vin and a high-frequency operation of an inverter circuit consisting of switching elements Q1 and Q2 and diodes D1 and D2 that are connected inversely in parallel with each both terminals of the switching elements Q1 and Q2. Then, the capacitance value of the capacitor C4 is set in a direction for setting the current waveform of an input current Iin to nearly sinusoidal waveform near the center value of the variable range of the oscillation frequency of the inverter circuit.

Title: Automatic sound volume adjusting device
Inventor: YASUE NORIMI
IPC: H03G3/32
Filed: 1991-06-04
Abstract: PURPOSE:To enjoy music or the like in a proper sound volume without being troubled by surrounding sound by catching the loudness of the surrounding sound with a microphone and controlling the sound volume of a reproduction signal in a proper volume. CONSTITUTION:A surrounding sound is detected by a microphone 5 and the result is outputted as an electric signal. The output signal amplified, detected and filtered by a level detection circuit 6 and the result is outputted as a signal representing the quantity of an external sound. A sound volume control circuit 3 adjusts automatically the reproduced sound signal incoming from a headphone stereo main body 7 to have a proper sound volume designated in advance. Then the control circuit 4 receives a command signal from a remote control section 2 to control each configuration block of the headphone stereo main body 7 and the sound volume control circuit 3. Thus, a sound signal in response to the control is sent from the sound volume control circuit 3 and a reproduction with a proper sound volume is outputted from the headphone 1.

Title: Magnetic recording medium
Inventor: YANO AKIRA
IPC: G11B5/66
Filed: 1992-05-25
Abstract: PURPOSE:To enhance the recording and reproducing characteristic of the magnetic recording medium by a method wherein an anisotropic main axis is set within a specific angle range from the waist-face vertical direction and the angle dependence of a coercive force which is measured by turning the main axis at a specific angle within slope face including a substrate traveling direction is set as double-ridged. CONSTITUTION:In a vacuum evaporation apparatus, a filmlike substrate 1, a can roll 2, an oxygen-gas introduction pipe 3 and an evaporation source 4 which is composed of Co are installed, and an electron beam 5 is applied. By using the vacuum evaporation apparatus, a Co-O magnetic film having a prescribed thickness is formed on a polyethylene terephthalate film having a prescribed thickness. In order to change a magnetically anisotropic orientation, the initial incidence angle alpha and the final distance angle beta of a Co vapor are adjusted between, e.g. 0 and 65 deg.. Since the recording-density dependence of a reproducing output has two peaks near parts where angles made with the vertical direction are, e.g. -45 deg. and 15 deg., it can be judged as double-ridged. Thereby, it is possible to enhance the recording and reproducing characteristics of the magnetic recording medium.

Abstract: PURPOSE:To measure the extent of oscillation of a rotating shaft system in safety, accurately and efficiently, by detecting the extent of oscillation of the rotating shaft system by means of a nonocontacting displacement gauge in lieu of a dial gauge. CONSTITUTION:Through a jig 4 for a rotating shaft fitted atop of a rotating shaft system 1, the rotating shaft system 1 is rotated and when acceleration is carried on to some extent, the acceleration is stopped to allow the rotating shaft system 1 to rotate by its intertia. Noncontacting displacement gauges 12 are fitted to an upper bearing support 5, a lower bearing support 6, and a hydraulic turbine support 7, and their outputs are recorded on an oscillograph 13 to grasp the extent of oscillation of the rotating shaft system 1. When a voltage is applied from a driver 15, coils embedded in the displacement gauges 12 establish high frequency magnetic flux. Voltages proportional to the distances to the rotating shaft system 1 are developed across the displacement gauges 12 and those voltages are amplified by an amplifier 16 through the drivers 15 to be recorded on the oscillograph 13.

Title: Motor,circuit and method for controlling it
Inventor: KIISU AIBUO HOUMAN
IPC: H02P6/08
Filed: 1995-05-02
Abstract: PURPOSE: To correct a power factor by connecting a capacity for selectively limiting a current at the output side of a rectifier to the input terminal of the rectifier and changing a current which is given between positive and negative rails. CONSTITUTION: A rectifier 105 is connected between an AC power supply and a stator assembly body, and an input terminal 102 of the rectifier 105 is connected to a row of capacitors 301, 302, and 30N for limiting the current at the output side of the rectifier 105. Then, the capacitors 301, 302, and 30N are selectively connected to the input terminal 102 of the rectifier 105 and hence a current is supplied between a positive rail 121, and a negative rail 122 is changed. Due to the current change, the operating speed of a motor changes. For example, a slightly advancing power factor is given to the motor of a refrigerator, and a slightly lagging power factor is given to a compressor, thus correcting the power factor.

IPC: G01D5/36
Filed: 1981-08-25
Abstract: PURPOSE:To improve resolution without making the pitch of a scale fine, by generating three 120 deg. out-of-phase position signals. CONSTITUTION:Black and white stripes are arrayed at the same pitch of 30mum corresponding to index scales 21-23 of an optical position detection scale, and thus a main scale which has the position detection marks and is not shown in the figure is arranged. The index scales 21 and 23 are arranged with 120 deg. phase differences from the stripped marks of the main scale, and mask windows 21a and 21b are 180 deg. out of phase with each other. Differential amplification is imposed upon signals from two windows of each of the scales 21-23 to obtain three position signals 1-3 which are 120 deg. out of phase. Thus, position detection closer than that by one index scale is performed.

Abstract: PURPOSE:To obtain a device having excellent diaphragm thickness controllability by forming a diaphragm before a diffused layer is formed. CONSTITUTION:A nitride film 7, an oxide film 6 on a P-type silicon substrate 1 of a piezo resistance forming region are removed, the substrate 1 is etched to a P<+> type buried layer 4, and a diaphragm 8 is formed. Then, after the films 7, 6 are sequentially removed, an oxide film 9 is formed, and polycrystalline silicon 10 is deposited until a groove of the diaphragm 8 is filled in. Thereafter, the silicon 10 is etched until the substrate 1 is exposed, an oxide film 11, a nitride film 12 are formed, and the film 12 on the film 9 is removed. Then, the film 9 on the upper part of an N-type epitaxial layer 5 of the periphery of an N<+> type buried layer 3 is opened, B (boron) is diffused through the opening to form a P<+> type isolation layer 13. Thus, formation of the diaphragm is conducted before the isolation layer is formed, thereby forming the diaphragm 8 before concentration of the layer 13 is reduced.
