IPC: B23K26/38
Filed: 1986-09-22
Abstract: PURPOSE:To smoothen a heat cutting plane of silicon nitride sintered material by cutting the silicon nitride sintered material using inert gas by a laser beam and etching the cutting plane of the cut silicon nitride sintered material. CONSTITUTION:A member 10 to be cut made of the silicon nitride sintered material is cut by a laser beam machine 12. At this time, argon gas, etc., are injected from an injection port 14 of assisting gas of the laser beam machine 12 as the inert gas toward the member 10 to be cut. After the cutting of the member 10 is finished, the etching treatment is executed on the member 10 by etching liquid and a metallic silicon layer 16 is removed. The etching liquid is formed of the liquid which is made by mixing nitric acid with hydrofluoric acid with a ratio of three to one. The cutting plane of the silicon nitride sintered material can be smoothened by a simple way by this method.

Title: Dot picture compressing-restoring system
Inventor: ENDO HIROYUKI
IPC: H04N1/41
Filed: 1986-09-19
Abstract: PURPOSE:To obtain a stable and high compressibility by dividing a picture into small areas whose sides are dot period, compressing data setting the number of black(or white) picture elements in the respective small areas as a compression code and restoring a dot picture from the compression code. CONSTITUTION:A small area division means 1 divides the inputted dot picture into the small square area whose side is equal to the dot period. A black(white) picture element counting means 2 counts the black(or white) picture elements in the respective square small areas divided into small areas. A black(white) picture element number storage means 3 stores the number of black (or white) picture elements in the respective square small areas where the black(white) picture elements are counted. The number of black(white) picture elements of the respective small areas stored by the black(white) picture element number storage means 3 is set at the compression code of the respective small areas and the code train is transferred as the compressed dot picture data and used for the storage. A compression code interpretation means 4 interprets the inputted compression code train and fetches the number of the black picture elements of the respective small areas. A dot pattern generation means 5 generates the dot picture according to a previously specified rule from the number of the black picture elements of the respective small areas. Thus the compression having the stable, high compressibility can be executed, which is not commanded by the white and black pattern of the dot picture data.

Abstract: PURPOSE:To measure the direction and speed of a wind at the same time by forming many resistance thermometer bulbs at the outer periphery of the intermediate part of an insulating round rod at equal intervals and thin film electrodes which are connected to the resistance thermometer bulbs at their upper and lower outer peripheral parts. CONSTITUTION:The eight Pt resistance thermometer bulbs 2 which has 0.1mm width, 5mm length, and 3,000Angstrom  thickness are formed by DC magnetron sputtering at 0.29mm intervals on the outer peripheral surface of the insulating round rod 1 of Al2O3 with a 1mm outside diameter and 30mm length by using a metal mask. Then the eight Pt thin film electrodes which has 0.2mm width, 13mm length, and 1mm thickness are formed at 0.19mm interval by the same method on the outer peripheral surfaces of both the upper and lower side parts of the round rod 1 and connected to both the upper and lower ends of the thermometer bulbs 2 to obtain the wind direction, speed, and capacity sensor 4. This is processed in the air at 1,200 deg.C for one hour and the values of the thermometer bulbs 2 are adjusted by a laser to 50OMEGA. Consequently, wire breaking and contacting between adjacent thermometer bulbs are eliminated and many resistance thermometer bulbs with high resistance are obtained, so the direction and speed of the wind are measured at the same time.

Filed: 1994-08-25
Abstract: PURPOSE: To surely receive a transmitted information signal even when the temperature of a laser diode is changed by widening the band of a laser beam by driving the laser diode corresponding to a high frequency large signal, of which the frequency is larger than that of the information signal, in addition to the information signal. CONSTITUTION: By driving a laser diode 25 corresponding to an information signal S2 and emitting a laser beam L2 to be emitted from the laser diode 25 into a space toward a transmitting object, the information signal S2 is transmitted through the laser beam L2 propagated in the space to the transmitting object. Then, the band of the laser beam L2 is widened by driving the laser diode 25 corresponding to a high frequency large signal RF, of which the frequency is higher than that of the information signal S2, in addition to the information signal S2. Thus, even when the central wavelength of the laser beam L2 crosses an absorbing band, the abrupt light quantity fluctuation of the laser beam L2 and the mixture of noise can be effectively avoided.

Abstract: PROBLEM TO BE SOLVED: To conduct liquid injection and plug insertion into a charge port with a series of operations and simplify the liquid sealing work by inserting a previously plug-inserted injection tube into a filling port and filling liquid within a cartridge and, after that, pushing further the injection tube into the filling port. SOLUTION: A forefinger H2 and middle finger H3 are put on the bottom surface 831 of a holding frame 83 at both the side of holding an injection tube 83, and a thumb H1 is inserted into an introduction groove 836 of the holding frame 83, thereby holding an ink injection tool A via the rigid holding frame 83. A previously plug 66-fitted injection tube 81 is further pushed down after the completion of ink injection and, thus, the plug 66 is pushed and inserted into the filling port with a series of operation from the injection so as to facilitate the sealing work. Also, fixing the injection tube 81 to the rigid holding frame 83 prevents the injection tube 81 from tottering and allows ink injection to be implemented smoothly.

Abstract: PURPOSE:To prevent picture quality from deteriorating owing to the shadow of an electrode part. etc., by providing equipping the lens of the liquid crystal projection type display device with a phase grating part which has plural projections on its surface. CONSTITUTION:Part of the light from a light source 1 is directly transmitted through a diffusion plate 3 which makes the lights projected from the light source 1 and a reflecting mirror 2 uniform and the rest is converted by the reflecting mirror 2 into a parallel light beam, which is transmitted through said the diffusion plate 3, thereby irradiating a liquid crystal cell 4 from its back surface side R. The irradiation light after being transmitted through the liquid crystal cell 4 passes through a lens group 5 arranged almost at right angles to the optical axis 8 and is observed by an observer. The lens 6 in the lens group 5 arranged almost at right angles to the optical axis 8 is equipped with the phase grating part 9 having the projections on the surface on the side of the liquid crystal cell 4 and this phase grating part 9 has a lattice-shaped pattern with periodicity in one direction and is sectioned in a nearly sine wave shape. This phase grating part 9. therefore. blurs the shadow of the electrode part. etc., of the liquid crystal cell 4, so the shadow of the pixel electrode part and nonlinear element of the liquid crystal cell 4 is reducible.

Abstract: PURPOSE:To contrive high speed seek of a magnetic head and to retract the head manually at the time of malfunction of a driving device by driving the head in vertical movement with a head elevator mechanism interlocked with the rotation of a driving shaft driven by a motor provided on a fitting frame. CONSTITUTION:A carriage main body 17 is retained in a fitting frame to be capable of advancing and retreating in the parallel direction with a tracking direction of a magnetic disk D. A head advancing and retreating mechanism 18 is held by the carriage main body 17 to be capable of advancing to and retreating from this magnetic disk D.
