Title: Production of liquid crystal display device
Inventor: ONUMA KENJI
IPC: G02F1/13
Filed: 1986-07-17
Abstract: PURPOSE:To form a sealing material without thickening seal width in spite of a cell with a small cell gap and contacting a form plate with the surface of an orientation film by executing the letterpress printing of a prescribed pattern of the seal material for sealing liquid crystal by an elastic letterpress printing material. CONSTITUTION:The sealing material 12' is applied to a metal plate 11 on which many grooves 32 are engraved with 45-60 deg. angle to fill the grooves 32 uniformly with the sealing material 12', a roller 13 provided with the elastic letterpress printing material 14 is pressed to the material 12' while being rotated to transfer the sealing material 12' to the letterpress printing material 14 and then the sealing material 12' is transferred to the surface of a base 15. A projecting part 21 of the letterpress printing material 14 is part for transferring the sealing material 12' to the base 15 and a part other than the projecting part 21 is not contacted with the base surface. Thereby, influence to orientation is removed and seal thickness <=1mu can be available, so that a cell with a small gap can be prevented from the expansion of the seal more than required amount.

Title: Comparator
Inventor: WATANABE FUMIHIRO
IPC: H03K3/0233
Filed: 1981-10-21
Abstract: PURPOSE:To determine a minute hysteresis width with good accuracy for the input and output characteristics of a comparator, by changing a load current of an input differential stage depending on the output state. CONSTITUTION:When an input VI1 is smaller than an input VI2, a TRQ1 turns off, a TRQ2 turns on, TRs Q4, Q5, Q turn off and an output V0 goes to logic L. When the input VI1 is increased and brought close to the input VI2 and the sum of the emitter currents of the TRs Q6, Q1 is larger than the emitter current of the TRQ2, the TRQ2 turns off and the TRs Q4, Q5, Q7 turn on, the TRQ6 turns off and an output V0 goes to logic H. When the input VI1 is gradually decreased and equals to the input VI2, the TRQ4 turns off and the output V0 goes to logic L. The hysteresis width can freely be determined with the emitter current of the TRQ6 and a current I0 with good accuracy, and in using this circuitry for an IC circuit, the occupied area in the IC can be reduced.

Title: Fm demodulation circuit
Inventor: IDOKAWA KAZUHIRO
IPC: H03D3/00
Filed: 1989-06-30
Abstract: PURPOSE:To improve output distortion at the time of demodulation, to remove noise beyond a band of a filter and to improve a selectivity characteristic by allowing the center frequency of a narrow band tracking filter to accurately follow the instantaneous frequency of an input signal. CONSTITUTION:An input FM signal which is frequency-converted into an intermediate frequency by a front end is inputted to the narrow band tracking filter 7 whose center frequency follows the instantaneous frequency of the input FM signal.

Title: Wafer chucking device
Inventor: TONO HIDEHIRO
IPC: B23Q3/08
Filed: 1986-07-22
Abstract: PURPOSE:To enable a wafer to be suched on a chuck so that its surface is flattened even if the wafer has warpage, by composing this device of the following units: a chuck of a cross-sectional recessed shape, vacuum devices formed on inner and outer walls, a pressure regulator, and a sensor electrically connected with a controller. CONSTITUTION:A wafer is mounted above a chuck 11. A vacuum device 12 is then operated to exhaust the air between an inner wall 14 and outer wall 15. Then, because the chuck 11 is of a recessed shape, the central part 20 of the wafer 16 comes down to the position lower than the normal one. Therefore, a distance between the peripheral parts of both the wafer and the chuck 11 becomes small enough to attract and fix the wafer to the chuck. Successively, an optical sensor 17 measures a distance between it and the surface of the wafer 16, sending the measured result signal to a controller 18. The controller 18 computes pressure supply of the clean air supplied to the airtight part, which is generated by attracted and fixing the wafer 16 to the chuck 11, by using its sent signal. A pressure regulator 13 regulates the pressure in the airtight part to flatten the wafer 16.

Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To increase a range of a detectable inclination angle when an inclination of a surface to be detected is detected, to assure linearity in the case of calculating the angle and to accurately detect the angle. SOLUTION: A gradient of a recording surface 20A of an optical disk 20 is detected. A light irradiated from an LED 12 is reflected on the surface 20A through a lens 18, its reflected light is condensed by the lens 18, and incident to PD 14A to PD 14P disposed in a matrix state of 4×4 as reflected spot light. The reflected spot light is detected by the PD 14A to PD 14P, and the inclination of the surface 20 is detected by the distribution of the receiving amounts of the PD 14A to the PD 14P. When the inclination is calculated from the amounts of the PD 14A to the PD 14P, a weight coefficient is multiplied and calculated for the detection of the PD far from a center of the light receiving range, and hence linearity of the detected output when the angle becomes large is assured, thereby detecting the accurate inclination angle.

Title: Cladding tube for nuclear fuel
Inventor: YOKOTA NORIKATSU
IPC: G21C3/20
Filed: 1989-07-04
Abstract: PURPOSE:To achieve a greater integrity of a fuel cladding tube by arranging one or multiple kinds of ductile material films lined in single or multiple layers on the entire inner circumferential surface of a nuclear fuel cladding tube so that the ductility thereof is smaller toward the external layer side from the internal layer thereof. CONSTITUTION:This nuclear fuel cladding tube comprises a fuel cladding tube 1 made of a zirconium alloy, a ductile material 2 and a highly ductile material 3. The ductility of the fuel cladding tube 1 and the ductile material 2 and 3 is so arranged to be higher sequentially in the order thereof. When a stress is generated in the fuel cladding tube with a change in output of a furnace, a tensile stress works in the inner surface higher in a circumferential direction than the outer circumference thereof. At this point, as the highly ductile material 3 is higher in the ductility as compared with the fuel cladding tube 1 and the ductile material 2, it extends easily to ease a stress with a plastic deformation thereof. Moreover, the ductility higher toward the internal surface allows the releasing of the stress sequentially from the internal surface thereby making a mismatching harder to occur at a joint.
