Title: Substitution system of redundant line
Inventor: NAWAKI MASARU
IPC: H01L21/82
Filed: 1984-10-23
Abstract: PURPOSE:To shorten a time for substitution processing without increasing a chip area and requiring a laser trimmer by constituting a redundant-line substitution circuit for a semiconductor integrated circuit with a redundant line for relieving a defective position while containing amorphous silicon, a resistance value thereof changes to a low value from a high value when a fixed value or more of voltage is applied. CONSTITUTION:With a redundant-line activating circuit 1, a chin select signal CS is brought to a high level 'H' because a transistor Q1 is brought normally to a non-conductive state and a resistor 11 consisting of amorphous silicon also has high resistance, a signal 8 is brought to a low level 'L' when a transistor Q2 is turned ON, and a redundant line is not activated. When using the redundant line, the resistance of the amorphous silicon resistor 11 changes to a low value from a high value when a signal 'L' is transmitted over a pad PD1, a node 7 is brought to 'H' and the transistor Q1 is turned ON and the voltage of a power supply line VPP is increased to 12V. When the voltage of the power supply line VPP is returned to 5V and the transistor Q1 is turned OFF, the node 7 is brought to 'H' and the redundant line is activated even when the signal CS is brought to 'H'.

Title: Y/c separator circuit
Inventor: FUJII TOSHIKAZU
IPC: H04N9/78
Filed: 1989-08-30
Abstract: PURPOSE:To improve an S/N and horizontal resolution and to reduce the cost by giving au input video signal to an adder circuit not through a delay circuit so as to extract a luminance signal component. CONSTITUTION:A color signal extraction circuit 50 generates a chroma signal by introducing, e.g. a video signal of three consecutive horizontal scanning lines. An adder circuit 51 and 1st and 2nd intermediate value circuits 67, 68 apply the arithmetic processing with the input video signal and the chroma signal from the 1st and 2nd intermediate value circuits 67, 68 is outputted without retarding the input video signal. Thus, the input video signal is given to the adder circuit 51 without passing through a 1st delay circuit 48 to separate a luminance signal and a chroma signal. Thus, sufficient S/N and high horizontal resolution are obtained with inexpensive constitution.

Filed: 1990-08-25
Abstract: PURPOSE:To reduce a variation in an emitting angle of a light to be emitted from a condensing grating coupler by providing a reflection type grating coupler for forming part of a resonator for deciding the oscillation wavelength of a semiconductor laser at a part of an optical waveguide between the laser and the coupler. CONSTITUTION:A semiconductor laser 22 is end-coupled to an optical waveguide 23, and a laser light emitted from the active layer of the laser 22 is propagated to a waveguide layer 23b of the waveguide 23. The light is partly reflected at the part of the layer 23b corresponding to the forming region of a reflection type grating coupler 24 in a grating layer 23c of the waveguide 23, and fed back to the laser 22. Since the coupler 24 constitutes the part of an external resonator with respect to the laser 22, the gain of the laser 22 becomes large at a specific value lambdab (lambdab=NLAMBDA1) if a secondary Bragg reflection occurs in the coupler 24) to be decided by the effective refractive index N of the waveguide 23 and the grating period LAMBDA1 of the coupler 24, and the laser 22 stably outputs a laser light having a wavelength lambdab by a single longitudinal mode oscillation.

Title: Capacity type differential pressure transmitter
Inventor: AZEGAMI TADASHI
IPC: G08C19/02
Filed: 1985-10-08
Abstract: PURPOSE:To obtain a capacity type differential pressure transmitter with high precision by connecting an input terminal to a common connection point to which one-terminal sides of the 1st and the 2nd sensor capacitors which vary with differential pressure are connected. CONSTITUTION:A loop on the side of an electrostatic capacitor C1 or C2 is selected by opening and closing AND gates G7 and G8 complementarily with loop switching signals LS1 and LS2 from a microcomputer muCOM and a voltage is outputted to the output terminals of the gates G7 and G8. When the output level of a buffer gate G5 varies while either of those positive feedback loops is selected, positive or negative voltage variation is caused at the its input terminal. This voltage variation is fed back negatively to the input terminal of the gate G5 as a constant current (i) with a constant inclination and pulled back to the gate G5. The microcomputer muCOM is so controlled that frequency signals corresponding to respective capacities C1 and C2 generated on a line 13 coincide with each other and a variable voltage V is impressed to the gates G7 and G8. This voltage V is proportional to the differential pressure and distribution capacities CS1 and CS2 between a moving electrode 10 and a converting circuit are removed.

Title: Heat dissipation control device
Inventor: HATADA TOSHIO
IPC: F28F13/00
Filed: 1983-11-30
Abstract: PURPOSE:To obtain a heat dissipation control device with high reliability such as an apparatus loaded in artificial satellite or the like by a structure wherein elastic spheres containing fluid heat transfer medium therein and interposed between an expansion container and a radiator plate. CONSTITUTION:Heat transfer medium 11 is a fluid made of single phase substance, which is excellent in heat conduction. In addition, three kinds of shape memory alloys 8, 9 and 10 have higher working temperatures in the order named. The heat transfer medium 11 excellent in heat conduction is encapsulated in elastic spheres 12. When an apparatus loaded develops heat and the temperature of a panel 2 rises, the temperature in an expansion container 14 also rises. When said temperature in the container 14 reaches the specified value, at first, a shape memory alloy spring 8 extends so as to press a contactor plate 5 against the elastic spheres 12. The heat in the expansion container 14 is transmitted in the order of the contactor plate 5, the elastic spheres 12 and a radiator plate 6 in order to be dissipated in cosmic space. In proportion to the further increase of the calofic value of the apparatus 1, the shape memory alloys 9 and 10 extend in the order named, resulting in making the elastic spheres 12 flatter and flatter and consequently the heat quantity to be conducted to the radiator plate 6 more and more. Thus, the quantity of heat dissipation increases in proportion to the calorific value of the apparatus 1, resulting in keeping the temperature in the apparatus 1 at the specified value.

IPC: B65H7/10
Filed: 1992-07-31
Abstract: PURPOSE:To detect the side skew state of a paper sheet by constituting the detection means arranged in a paper sheet passage not to directly contact paper sheets. CONSTITUTION:A capacitor member 2 comprises two electrode bases 5 and 6 spacedly arranged in the side section of a paper sheet carrying passage and a gap through which paper sheets P pass and is connected to an oscillator 7, which applies high frequency voltage to the capacitor member 2.
