IPC: E06B9/24
Filed: 1992-12-07
Abstract: PURPOSE:To make it possible to adjust light permeability of a light modulation board promptly by mounting a piezo-actuator to one party of light modulation boards to which a light modulation member is interposed between two transparent boards and applying shearing force to the light modulation member and changing the light permeability. CONSTITUTION:A piezo-actuator X is installed to a second light modulation board 3 of a light modulation board P which is integrated by interposing a light modulation member 4, which changes light permeability, between a first transparent board 2 and a second transparent board 3. Then, voltage is applied to the actuator X so as to slide the transparent board 3 and apply shearing force to the light modulation board 4, thereby subjecting the board to deformation and changing the light permeability. A wedge-like span maintenance mechanism is installed to the transparent board 3 so that a definite span may be maintained even if the actuator comes to a halt. This construction makes it possible to control the light permeability of the light modulation board P with high accuracy.

IPC: H01J29/48
Filed: 1987-12-22
Abstract: PURPOSE:To enable the deflection of an electron beam based on deformation due to the magnetic field and the thermal expansion of a cathode to be avoided by arranging a conductor for allowing electric current to heat a cathode main body in parallel with the cathode main body on the rear surface of the cathode main body. CONSTITUTION:The cathode 2 is composed of a cathode main body 11 which radiates an electron beam, the first conductor 12 which is arranged on its rear surface in parallel with the cathode main body 11 and is connected to the cathode main body 11, and the second conductor 13 through which the conductor 12 is connected to a heating power source 3. When thermal expansion is generated in each place by means of a heating current flowing from the power source 3 flows, the extending direction M of the thermal expansion along the horizontal direction at each end portion of the cathode main body 11 is the same direction as the extending direction N of the thermal expansion along the same horizontal direction of the conductor 12 which is on the rear surface of the cathode main body 11. With this arrangement, distortion due to the thermal expansion of the cathode and an influence upon the magnetic field due to the heating current can be avoided so as to be able to decrease the deflection of the electron beam at most.

Abstract: PROBLEM TO BE SOLVED: To decelerate clock frequency by finding out a period continuing a high level and a period continuing a low level from data obtained by sampling a detection signal at a clock and reproducing the detection signal so as to synchronize it with the clock based on the ratio of both the periods.

The frequency of a clock is set up to 20.48 MHz based on the transmission speed 2048 kbps of the detection signal. When the count value is 5 to 14 or 15 to 24, '1' and '0' continuous length judging circuits 35, 36 judge the inverted point pattern of the Manchester code respectively as '11' and '00' or '1' and '0'. A four-input data selective switching judging circuit 41 selectively sends a pattern generated from a clock by a data generation part 39 based on the judgement to an output terminal 41A as demodulated data.

Title: Method for producing semiconductor substrate
Inventor: FUJINO SEIJI
IPC: H01L21/02
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce production cost of an SOI substrate while preventing production yield from lowering in the way of a process due to generation of particles. SOLUTION: Two sheets of wafers are bonded through an oxide film 3 such that the major faces of a base wafer 1 and a bond wafer 2 face each other. Following to the bonding process, end parts of the bonded wafer are subjected to beveling. Rear surface of the bonded wafer 4 on the bond wafer 2 side is then subjected to surface grinding and mirror polishing to obtain an SOI layer of specified thickness. Since beveling is carried out after finishing heat treatment for bonding, conventionally required edge grinding or masking taping or alkaline etching process can be eliminated and production cost of a SOI wafer can be reduced. Furthermore, conventionally inevitable terrace structure can be eliminated and production yield can be prevented from lowering by suppressing generation of particles in the way of process due to stripping of a deposited film from the terrace part.

Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To produce a bean curd excellent in texture, taste or the like by minimizing waste components such as a soybean refuse and incorporating components essential to raw material soybeans in the bean curd as much as possible. SOLUTION: This soybean flour-containing type bean curd is produced by mixing a soybean flour obtained by carrying out the direct grounding treatment of raw soybeans in a raw ground soybean liquid or a soybean milk, preparing a soybean flour-containing soybean milk, adding a soybean milk coagulant to the prepared soybean flour-containing soybean milk, thermally coagulating the resultant mixture and producing the bean curd. Disposal of components as a soybean refuse is eliminated to improve the utilizing efficiency of the raw material soybeans and the production cost of the bean curd is reduced to further reduce the amount of the waste soybean refuse and the load on the environment by the amount of a part of the soybean milk replaced with the soybean flour.  Since components thrown away as the soybean refuse can be incorporated, dietary fibers or the like can abundantly be contained in the bean curd. The bean curd can be provided with both a thick taste and a firm and smooth texture when eaten in a warm state by using the soybean flour and the soybean milk in combination.

IPC: H01L29/80
Filed: 1988-12-23
Abstract: PURPOSE:To reduce irregularity of breakdown strength between cathode and gate or between source and gate by constituting an impurity diffusion region for a gate region as a double diffusion region composed of an inner region in which high concentration impurity is diffused and a peripheral region which is arranged outside the inner region and in which low concentration impurity is diffused. CONSTITUTION:An impurity diffusion region 2 for a gate region is constituted as a double diffusion region composed of an inner region 2b in which high concentration impurity is diffused, and a peripheral region 2a which is arranged outside the inner region and in which low concentration impurity is diffused. That is, the impurity diffusion region 3 of a cathode region intersects the peripheral region 2a, in which low concentration impurity is diffused, of the impurity diffusion region 2 subjected to double diffusion for the gate region. As a result, when the position of intersection changes, the deviation of impurity concentration for the gate region is small at the intersection, and the impurity concentration variation width of the impurity diffusion region 2 for the gate region at a junction point or in the vicinity the junction point becomes small. Thereby, the irregularity of breakdown strength between cathode and gate or between source and gate can be reduced.

Abstract: PURPOSE:To always achieve the focussing of a laser for exposure by automatically tracking the variation in external variable factors such as the reflectance of a master disk glass, intensity of a focus controlling laser, etc. automatically. CONSTITUTION:A focus controlling laser beam; 4 is reflected on the recording surface of the master disk 10, transmits through an objective lens 22, a dichroic mirror 18, a 1/4-wavelength plate 21, a beam splitter 20, and an astigmatism generating optical system, and is made incident to a quad-divided photodetective element 26. In the element 26, a signal corresponding to a focus error is generated, so that a focus error signal F is generated by a focus error generation circuit. At the same time, a signal S1 corresponding to the total quantity of light of the focus controlling laser beam incident to the element 26 is generated, so that a correction voltage Vref1 in proportional to this light-quantity signal S1 is impressed to the signal F, and these two signals are superimposed with each other, and a voice coil 24 is servo-controlled with a signal resulting in said superimposition. The gain of a control circuit 32 is variously changed to set in such a value as to optimize a write to the master disk, thus a correction voltage well following the variation in an external variation factor can be applied.
