Title: Polychromatic liquid crystal display device and its driving method
Inventor: TANI KAZUTSUKA
IPC: G09G3/18
Filed: 1981-08-19
Abstract: PURPOSE:To enable a polychromatic display with a small number of electrodes by filling a liq. crystal with a dispersion type dielectric anisotropy into each region A in a display panel having electrode substrates oriented parallel to the surface and a liq. crystal with p-type dielectric anisotropy into each region B and by dissolving n-type and p- type dyes with different hues in the regions, respectively. CONSTITUTION:As shown by figure 1 different liq. crystals and different dyes are mixed and filled into a large number of regions A, B arranged in a liq. crystal panel having electrode substrates 6, 7 oriented parallel to the surface at the insides. Dp and Dn are different from each ohter in inherent hue. When AC voltage is applied to the electrodes 4, 5, the molecular orientations of the liq. crystals and the dyes in the regions A, B and a colored state are attained as shown by figure 2. At 0 V voltage the region A is colored, at voltage L the region B is colored, and at voltage H both the regions A, B are colored. Accordingly, when the panel is observed from a relatively long distance, the panel assumes Dp color at 0V voltage, Dn color at voltage L and a compound color of Dp color and Dn color at voltage H as a whole. By changing over the frequency and value of AC voltage for driving, a trichromatic switching display can be conducted.

Title: Optical head
Inventor: NAKAGAWA KATSUJI
IPC: G11B11/10
Filed: 1988-05-26
Abstract: PURPOSE:To attain overwriting of a magneto-optical disk and to shorten the access time of a device by adding a light source for overwriting. CONSTITUTION:An optical head is constituted of a recording/reproducing light source 1, an overwriting light source 2, a half mirror 3, a detecting beam splitter 4, a condenser lens 5, and a reflected light detecting optical system 6.

IPC: F02D13/02
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of running stability caused by a varied valve timing when a vehicle skids. SOLUTION: A variable valve timing mechanism(VVT) 13 varies a valve timing of an intake valve 23, depending on pressure of oil supplied from an oil pump 62. An oil control valve 60 controls the oil pressure applied to the VVT 13. An electronic control unit(ECU) 16 controls the OCV 16 to vary the valve timing of the intake valve 23 at a predetermined changing speed. Each of speed sensors 202L, 202R, 203L, 203R detects rotational speed of driving wheels 200L, 200R and driven wheels 201L, 201R. The ECU 16 calculates slip ratio of a vehicle C based on detected signals output from the speed sensors 202L, 202R, 203L, 203R, respectively. Depending on the slip ratio, the ECU 16 controls the OCV 60 to change the speed of varying the valve timing.

Title: Vacuum degree control method
Inventor: YAGUCHI SEIICHI
IPC: G11B15/58
Filed: 1985-06-17
Abstract: PURPOSE:To execute the economical control by controlling the degree of vacuum based upon the tape suction position. CONSTITUTION:A magnetic tape 8 remains stationary at the position where the force sucked to vacuum parts 4 and 5 and the torque of the reel are balanced. Here, when the degree of vacuum comes to be large, the magnetic tape 8 is stationary at the position where the tape is pulled out to the inside of the vacuum parts 4 and 5, as shown by the dotted line. At such a time, since the displacement quantity of the magnetic tape 8 is determined corresponding to the changing quantity of the degree of vacuum, when the vacuum pump not shown in the figure is controlled so that the displacement quantity can be zero, the tension of the magnetic tape 8 is kept at the constant value. Thus, the high-priced air pressure sensor comes to be unnecessary and the economical efficiency is improved.

Abstract: PURPOSE: To apply proper quantity of heat input over the entire welding current range by generating the timing pulses synchronized with AC input, dividing down the frequencies thereof to meet the feed speed of a wire, and generating the trigger  pulses synchronized with these.  
     CONSTITUTION: The clock pulses regulating the generation times of trigger pulses (thyristor 71W76) emitted from a trigger circuit 10 are generated by a clock pulse generating circuit 11. Such clock pulses are conducted to a frequency dividing circuit 12, by which the number of pulse is thinned out in such a way that the trigger pulses are generated from the trigger circuit at the frequencies corresponding to the wire feed speed. A switching element is conducted and controlled by such trigger pulses. Thereby, the number of the pulses generated per unit time can be changed and good welded beads are easily obtained.

Abstract: PURPOSE: To prevent scatter of acid mist, by covering the cathode with masking material, collecting the acid mist released from the cathode in the upper part of the masking material, and separating into electrolyte and hydrogen, when treating Al or other material in aqueous solution of sulfuric acid by anodic oxidation process.  
     CONSTITUTION: In an anodic oxidation treatment bath tank 1 filled with an electrolyte 2 such as aqueous solution of sulfuric acid, Al or other metal to be treated as the anode, and a cathode 3 covered with masking material 4 made from acidproof fiber such as cotton flannel and saran are suspended. The upper end of the masking material 4 should be higher than the liquid level in the bath tank, and a trap 5 of acid mist is formed. Above the trap 5 is formed a shield 6, which is secured to an overflow trough 7 through a linkage 8. Hydrogen generated from the cathode 3 during anodic oxidation treatment by electrolysis is changed to an acid mist together with the electrolyte and climbs the masking material 4 to be collected in the acid mist trap 5. Then, hitting against the shield 6 provided above, the mist is separated into hydrogen and electrolyte, which are separately recovered. Therefore, corrosion of the machines and facilities due to scatter of mist from the treatment tank 1 may be prevented.

IPC: H03B5/32
Filed: 1983-07-18
Abstract: PURPOSE:To expand the frequency variable range and also to improve the control sensitivity by connecting an expanding coil and plural varactor diodes in series with a crystal oscillator and controlling said diodes by a common DC control voltage. CONSTITUTION:A capacitor 5 is connected between input terminals of an amplifier 1 and a series connection circuit comprising a crystal oscillator 6, an expanding coil 7 and two varactor diodes 8, 9 is connected between the one input terminal of the amplifier 1 and ground. A connecting point between the diodes 8, 9 is connected to an input terminal 12 of a DC control voltage Vc via a resistor 11. Thus, the diodes 8, 9 are controlled at the same time by the control voltage Vc. In this case, the minimum capacitance of the combined capacitance of the two diodes 8, 9 is smaller than that of one varactor diode. That is, the minimum capacitance is halved. Then the frequency variable range is expanded accordingly. Since the minimum capacitance is halved, the control sensitivity is improved so much.
