Patent JP-S62242831-A (JP)
Title: Pressure detector
Inventor: NISHIDA MINORU
IPC: H01L29/84
Filed: 1986-04-15
Abstract: PURPOSE:To mass-produce small-sized chips and to detect high proof pressure by using silicon nitride ceramic for a diaphragm and soldering it to a body. CONSTITUTION:When pressure is applied to a sensing element 1, the chip 11 is strained as a periphery-fixed circular diaphragm at a part corresponding to the circular hole 10a of the body 10; and strain gauges 13a and 13c increase in resistance value by receiving tensile stress and strain gauges 13b and 13d decrease in resistance value by receiving compressive stress. The four strain gauges 13a-13d form flexible constitution, so when a constant voltage E is applied, for example, between electrodes 14a and 14c and a voltage between electrodes 14b and 14d is outputted, an output corresponding to variation in liquid pressure is obtained. This output is amplified by a processing circuit 3 and outputted from the 2nd lead wire 8 after temperature compensation, thus detecting the pressure.

Title: Cd drive
Inventor: OMURA HISASHI
IPC: G11B20/10
Filed: 1990-03-29
Abstract: PURPOSE:To improve the operability in the case of reproducing a signal while a format with a different sampling frequency is switched by oversampling a demodulated digital signal and converting a sampling frequency of a digital signal into a sampling frequency received by a D/A converter to be connected. CONSTITUTION:A CD-ROM decoder 2 detects a synchronizing signal from a data demodulated by a CD processor 1, processes the data and outputs an ADPCM data. An ADPCM decoder 3 demodulates and outputs an ADPCM data from the CD-ROM decoder 2 into an audio data. A digital film 4 applies oversampling to an audio data demodulated by the ADPCM 3. A digital audio interface 6 adds auxiliary information to an output of a signal selector 5 and modulates the signal and outputs the result to a D/A converter unit. Thus, the operability is improved in the case of reproducing a signal while a format with a different sampling frequency is selected.

Abstract: PURPOSE: To increase adhesiveness of a stator coil and a synthetic resin thus improving riliability by impregnating the synthetic resin into the stator coil and fixing the coil to an iron core after the surface of the stator coil is treated by means of low temperature gas plasma.  
     CONSTITUTION: A stator 5 is placed in a treating tank 30, and the tank is vacuumed by means of a vacuum pump 31, then an inert gas is charged. A high frequency power is supplied to a high frequency coil 29 to produce an electrodeless exitation in the tank 30, thus creating a low temperature gas plasma condition. With this  high frequency energy, a waterproof synthetic resin film on a stator coil 6 is treated.  Then the coil is locked by supplying a synthetic resin such as an epoxy resin into a  slot 22 of the stator. By so doing, adhesiveness of the waterproof synthetic resin on  the surface of the stator coil 6 and the synthetic resin used for locking the coil, is  increased; thus eliminating dislocation and deformation of the stator coil as well as  preventing inappropriate insulation.

Abstract: PROBLEM TO BE SOLVED: To obtain a sufficient interference effect and excellently reproduce a data image of an object beam when recording a Fourier-transformed image of the object beam holding data information as a hologram. SOLUTION: A data image of an object beam is Fourier-transformed, and zero-order to, for instance, 5th order light components of the Fourier-converted image are transmitted through a light transparent part 21 of a shading body 20 to irradiate an optical recording medium therewith. The light transparent part 21 has a constant light transmittance in all the area.  Parallel light of spatially constant intensity is transmitted through an intensity modulation filter 17 having such a spatial transmittance distribution as the transmittance is maximal at the center part and decreased as it goes down to the periphery, and the transmitted light is transmitted through the light transparent part 21 of the shading body 20, or directly emitted reference light onto the area of the optical recording medium irradiated with the zero-order to 5th order light of the Fourier transformed image and not through the light transparent part. Then, the center part where the reference light is at the maximum in the intensity is made to be superimposed on the zero-order light in which the Fourier-transformed image is at the maximum in the intensity. At the reproduction, reading light having the same wave front as the reference light in recording is irradiated.

Filed: 1987-04-09
Abstract: PURPOSE:To surely prevent malfunction by compensating an output point level of a transistor (TR) constituting a gate by the charge/discharge of the output point due to the conduction of a 2nd TR. CONSTITUTION:A 1st TR 1 constitutes a switching gate and an input signal In passes synchronously with the clock pulse phi as the switching input. The 2nd TR 10 is conducted synchronously with the clock pulse phi as the switching input and before the 1st TR 2 is conductive, the output point P is charged to compensate the high level of the input signal In. Thus, an output having an optimum level is extracted and if the logic circuit such as an inverter 6 exists in the next-stage, the malfunction due to the fluctuation of the input threshold voltage is prevented.

Title: Frequency-stabilized light source
Inventor: KAWAKAMI JUN
IPC: H01S3/13
Filed: 1993-03-24
Abstract: PURPOSE:To simultaneously realize the control of a frequency and the control of a phase with high stability without generating a crosstalk by a method wherein a frequency modulation signal at a modulating frequency and a phase modulation signal at a modulating frequency have numerical values which are close to a nearly identical value and they have a frequency difference which can be isolated easily by a frequency isolation means. CONSTITUTION:A beam of light radiated from a semiconductor laser 1 is branched by a beam splitter 9, a part is incident on a frequency reference 2 and the other part is incident on an external resonator 3. Then, an oscillator 23 oscillates and outputs a frequency modulation signal S1 at a modulating frequency f1. The frequency modulation signal S1 makes an AC current flow to a coil 17, and it modulated the reference position of a frequency for the frequency reference 2. On the other hand, an oscillator 31 oscillates and outputs a phase modulation signal S6 at a modulating signal f2. The phase modulation signal S6 applies a voltage to an electrostrictive element 6, and it modulates an optical path length between the semiconductor laser 1 and the external resonator 3. Thereby, since the modulating frequencies f1, f2 become numerical values which are close, a crosstalk is eliminated.
