Title: Color liquid-crystal display panel for television
Inventor: HANDA SHIYUNJI
IPC: G02F1/133
Filed: 1978-03-22
Abstract: PURPOSE: To improve a color balance contrast by reducing area of electrode intersection parts equivalent to blue, red and green filters in the order, by fixing the width of an effective voltage, applied to a corresponding liquid crystal to the maximum value integrally, and by easily obtaining a voltage for obtaining a half tone.  
     CONSTITUTION: Inorganic thin-film color filters 11 are provided between liquid crystals 9 and clear electrodes 8 of the 90°-twist structure and form red, blue and green filters in the row direction by turns. When this liquid-crystal display panel is viewed by a trnsmissive pattern, white incident light is cut by deflecting plate 10 at the opposite side with a voltage supplied to the liquid crystal at matrix electrode cross part, less than the threshold level of the liquid crystal, so that the entirety will be dark. Then, various colors can be obtained from transmitting light by independently controlling the gradient of liquid-crystal molecules at filter parts of three cross parts among respective picture elements. Now, reducing in area filters in the order green, red and blue corresponding to the brightness makes it possible to fix effective voltage values applied to liquid crystals equivalent to respective filters to the maximum values integrally, so that half-tone voltage division will become easy with an excellent balance contrast.

Abstract: PURPOSE:To easily prevent it without complication that the oscillation center wavelength of an LD fluctuates on account of temperature fluctuation. CONSTITUTION:The light output of an LD 11 of an LD module 1 in which a Peltier cooler 12 is contained for cooling is made to pass an optical narrow band filter 2 which passes only the wavelenth to be set, and inputted in a PD 3. The output of the PD 3 is inputted in a temperature adjusting circuit 4 which controls the Peltier cooler 12. The temperature adjusting circuit 4 controls the Peltier cooler 12 so as to make the light entering the PD 3 maximum, and sets the temperature. Thereby the light whose wavelength is set can always automatically obtained.

Abstract: PURPOSE:To reduce a secondary distortion by equalizing the rise time and the fall time of an output signal. CONSTITUTION:When a transistor TR 1 is turned on and a TR 2 is turned off, the current of a current source 9 becomes the emitter current of a TR 3, and the same current as this current is supplied to an output terminal 10 by a current mirror circuit 8, and the voltage of the output terminal 10 rises with a time constant based on this current and an output impedance. When the TR 1 is turned off and the TR 2 is turned on, the current of the current source 9 becomes the emitter current of a TR 6, and the voltage of the output terminal 10 falls with a time constant based on this current and the output impedance.

Title: Method of burning fuel mixture containing heavy oil and water
Inventor: OGURA TSUGITOSHI
IPC: F23K5/00
Filed: 1988-02-17
Abstract: PURPOSE:To improve a combustibility and reduce unburned amount of fuel, by heating oil-in-water(O/W) type fuel emulsion from a phase-inversion initiation temperature to a phase-inversion completion temperature just before subjecting fuel to combustion. CONSTITUTION:Immediately before combustion, an O/W type fuel mixture containing a heavy oil and water is heated from the phase-inversion initiation temperature to the phase-inversion completion temperature, whereby the oil-in- water type fuel emulsion is phase-inverted to a water-in-oil(W/O) type fuel emulsion. When the phase-inverted W/O type fuel emulsion is subjected to combustion, water particles contained therein is broken off into fine particle in misty state, whereby oil drops are finely divided and diffused in the emulsion, which results in increased combustion rate and improved combustibility as well as reduced amount of unburned fuel.

The release side of the first member 4 is joined with the second member 6, and is covered so as to form an inner guide passage 8 extending in a longitudinal direction. It is thus possible to improve surface rigidity, and it is also possible to surely prevent generation of radiating noise. Since a structure is simplified, manufacture is facilitated so as to reduce costs.

Abstract: PURPOSE:To prevent rotation of an electronic component inside a cavity and to realize stabilization by providing a shutter which is opened and closed in a direction rectangular or parallel to a feed direction of a taping component at a position wherein an electronic component is unloaded synchronized with feed of the taping component of a feed wheel. CONSTITUTION:Generally, a longitudinal direction of an electronic component 1 contained in an electronic component aggregate 2 is a rectangular direction to a feed direction of a taping component. A shutter 9 is constituted to be closed excepting when an electronic component is unloaded. When the electronic component 1 is unloaded, a level 10 is pushed in Z-direction; then, a level 11 rotates in a direction to open a shutter 9 around a fulcrum 12. A spring 13 always applies force to the lever 11 in a direction to close the shutter 9. Since clearance required for rotation in a longitudinal direction of an electronic component does not exist, rotation of an electronic component can be prevented.

IPC: H04B7/08
Filed: 1989-02-13
Abstract: PURPOSE:To attain automatic tracking to a broadcast station broadcasting one and same program with less multi-path by detecting an error rate of a digital data corresponding to each antenna input and selecting an antenna input with less error rate. CONSTITUTION:An error rate detection means 6b of a main microcomputer 6 detects an error rate of an RDS code outputted from error detection/correction circuits 5a, 5b corresponding to antenna inputs A, B, and a comparison means 6c compares the error rate of the antenna inputs A, B. When a multi-path is large, since the error rate is larger, a selection means 6d of the main microcomputer 6 selects the antenna input A or B with leas error rate. Thus, the changeover to a station having much multi-path with the degree of signal intensity only is avoided.

Title: Method for inspecting defect of magnetic disk medium
Inventor: SAKAI MAKOTO
IPC: G01N27/72
Filed: 1995-02-22
Abstract: PURPOSE: To efficiently execute defect inspection by providing a floating head or magnetic recording head with a strain sensor and detecting the output from the strain sensor simultaneously with ration of a magnetic disk medium. CONSTITUTION: Friction force is generated between a magnetic recording medium and the floating head when rotation is started from the state in which both are held in contact (contact start). The strain is generated in an aluminum sheet 6 by the friction force. The strain gage 7 stuck to the aluminum sheet 6 detects the strain and outputs a voltage signal. This voltage signal is amplified by an amplifier 8 and is subjected to A/D conversion by an A/D converter 9 and thereafter, the voltage is outputted to a CPU 5. The friction force is detectable from the result thereof. The inspection is executed within the time from the contact start until the rotation rises to the number of revolutions at which the warranted flying height is inspected in the load position of the magnetic recording medium and, therefore, there is no time loss.

Filed: 1990-02-16
Abstract: PURPOSE: To enable a reliable precise switching operation by lengthening a switching lever so as to be adaptable to a control process larger than a switching process of a switching pin. CONSTITUTION: In the case of a closed circuit operation of a rotary latch 1, a power transmission pin 5 is moved from an open circuit position A to a closed circuit position C. A switch lever 4 is subject to a swivel action by tensile force of a coil tension spring 9, and an edge of a grip arm 4a first comes into contact with a periphery of a power transmission pin 5 and is held in a contact state until the pin reaches a closed circuit position B. In this case, compensation of a swivel length between the latch 1 and the lever 4 is supported by sliding of the pin 5 at an edge of the grip arm 4a in contact with the pin 5. Immediately before reaching the switching position B, a rear side edge of a push arm 4b pushes down a switching pin 12 at a final stage of the swivel process.  Here, since the lever 4 is pulled toward a stopper 14 by a residual spring deviation pre-stress of the coil tension spring 9, the switching lever 4 is fixed.
