Title: Repair welding method of mg alloy casting
Inventor: TANAKA KAZUO
IPC: B23K9/23
Filed: 1983-08-01
Abstract: PURPOSE:To decrease weld cracking in a weld metal and a weld heat-affected zone by chipping the defective part of an Mg alloy casting in the range where the chipped part is not penetrated to the rear to form a groove and welding said part while cooling the same from the rear. CONSTITUTION:Formation of a groove necessitates adjustment of chipping depth according to the wall thickness of a part to be repaired. The lower limit of the wall thickness in the groove bottom involves no problem as far as there is no leakage of water to the surface on account of burn-through by welding. Uniform cooling is difficult and the residual stress by weld heat is excessive if the part to be repaired is too large. Cold water, liquefied carbon dioxide, liquid nitrogen, etc. are generally used as a refrigerant, for which a method of running the refrigerant with a hose, etc., a method of spraying the same in the form of a mist, etc. are utilized. TIG welding, MIG welding, gas welding, etc. are available for the welding method, among which AC TIG welding is most preferred. Welding conditions require >=50A welding current as the quantity of heat is deprived of by cooling. Welding with 60-110A is more preferable to assure the amt. of molten metal and arc length. The welding current is required to be maintained at <=160A as there is the possibility of blowing off the molten Mg if said current is too large.

Abstract: PURPOSE:To moderate erosion of blades due to water drops contained in a steam, by a method wherein an outer ring part of a nozzle in a step immediately upstream of an intermediate step part is provided with a plurality of through- holes for communicating a space on the upstream of the nozzle and a space on the downstream side to each other. CONSTITUTION:The outer ring part 17 of the nozzle immediately upstream of an inflow part 16 for the intermediate step where a primary steam 3 and a secondary steam 6 simultaneously flow in is provided with a plurality of through- holes 18 (each of which communicates the space on the upstream side of the nozzle and the space on the downstream side to each other) in the peripheral direction at an angle of inclination of 70-75 deg.. Jets 19 having high speeds and large swirls are generated from the through-holes, and the secondary steam 6 is positively deflected to the side of the tips of the blades, thereby contriving to moderate the erosion of the blades due to water drops contained in the steam.

Title: Drive transmission
Inventor: SUGITA SATORU
IPC: B65H5/06
Filed: 1995-06-08
Abstract: PURPOSE: To prevent the emission of abnormal sound and abnormal wearing or vibration caused when rotors are strongly pushed to each other by supporting a second rotor so as to move the force received from a first rotor in the direction of the resultant force of the force received from a third rotor. CONSTITUTION: When drive force is transmitted to a gear G1 from an input gear 104, the force is transmitted to gears G2 and G3 in order. At this moment, biting force Fdt around the gear 1 is generated in the gear 2, working to let the gear G2 insert between the gears G1 and G3. On the other hand, the rotary shaft 102 of the gear G2 is fixed to a swing arm 103, generating component force in the direction to rotate the gear G3 during the drive of the swing arm 103.  Since a clearance δ is provided between the shaft 102 of the gear G2 and its shaft hole, even if the moving direction of the swing arm 103 is different from the working direction of the biting force Fdt of the gear G2, the gear 2 can move to the position allowing the gear 2 to secure proper distance from either the gear G1 or gear G3 on the working line of the biting force Fdt due to the roll contacting an adjacent gear.

Title: Automatic segregation apparatus for mixed waste
Inventor: TAKI YOSHITO
IPC: B07B1/22
Filed: 1994-05-31
Abstract: PURPOSE:To provide an automatic segregation apparatus which can segregate paper sheets such as news paper efficiently from mixed waste by using a trommel screen. CONSTITUTION:The trommel screen 5 of an automatic segregation apparatus is equipped with a pair of paper sheet pressing frames 60A, 60B in the cylindrical main body 51. The frames 60A, 60B are connected with each other so that the primary end side can rotate freely to the inner wall. When the cylindrical main body 1 rotates, the frames 60A, 60B revolve by the tare weight around the primary end to catch paper sheets transferred in the inside so as to press them on the inner wall of the main body 51. The pressed paper sheets drop down along the inner wall and are recovered by being discharged from a discharge opening for paper sheets opened downward. The paper sheets can be recovered efficiently by the frames.

Title: Semiconductor strain gauge fabrication method thereof
Inventor: SHIBATA TOSHITAKA
IPC: H01L49/00
Filed: 1991-05-17
Abstract: PURPOSE:To improve the sensitivity of a gauge even when the gauge is reduced in chip size by making the thin-walled portion of a semiconductor strain gauge larger, in size, than the size of the chip, and by reducing the thickness of that portion to a much smaller extent. CONSTITUTION:A hole 7 is formed on a silicon substrate 1 in such a manner as to pass through the substrate, from the exposed surface to the coated surface thereof, and to reach a dielectric layer 2 laid on the coated surface of the substrate 1. A hole 8 is also formed in the dielectric layer 2 to be continued to the hole 7. The hole 8 in the dielectric layer 2 is larger, in diameter, than the hole 7 which is formed on the exposed surface of the substrate 1. Since only a silicon layer 3 extends over the hole 8 of the dielectric layer 2, the portion of that silicon layer, occupied by the hole 8, serves the smaller thickness portion of a semiconductor strain gauge. Accordingly, the thin-walled portion of the gauge can be formed larger than the size of the chip on the substrate 1. Moreover the thin-walled portion is defined by the thickness of the silicon layer 3 that is laid over the dielectric layer 2, which allows the thin-walled portion to be accurately reduced in thickness. Thus, the sensitivity of the gauge can be improved with a smaller chip size.

A file can be transferred to the device 4 from a device 7 under the control of this device 2. By providing the device 6, etc. in this way, a quickness and an exactness of a fault recovery can be improved.

Abstract: PURPOSE:To increase the diffusiveness of a microlens and to improve the brightness of a finder image even in the case of facilitating focusing by gradually inclining the optical axis of the microlens arranged on a mat surface by a prescribed ratio. CONSTITUTION:Many recessed microlenses 3 are installed on the mat surface of a focusing screen 1 without leaving clearance so that curved faces adjacent in a honeycomb shape come into contact with each other. Each microlens 3 is formed so that it is made spherical on the central part of the focusing screen 1, and the apex thereof may be deviated to the outside of the focusing screen 1 as it moves away from the center, and also, the curvature thereof may become smaller as it becomes closer to the outside, that is, the optical axis passing through the apex of each microlens 3 goes toward the central axis of the focusing screen 1. Then, light D made incident on the focusing screen 1 is diffused by each microlens 3, and also, diffused and transmitted light is efficiently converged within a pupil angle alpha due to such effect that the apex of each microlens 3 is shifted in the outward direction of the reticle 1, and then, the occurrence of interference fringes on the focusing screen due to diffraction phenomenon is also prevented.

Filed: 1981-09-11
Abstract: PURPOSE:To extend the reception time and extend the receiving Doppler spectrum band width, by controlling the beam radiated from an antenna so that this beam is directed toward a predetermined target direction. CONSTITUTION:A synthetic aperture radar mounted on an airplane radiates radio waves to a target from a point A through a point C to receive and record reflected waves and records momentarily the ground speed, the altitude, the target azimuth, etc. At this time, the synthetic aperture radar antenna mounted on the airplane is so controlled that the target is the beam center. Thus, the beam direction is so controlled that radar radio waves are irradiated around the target to extend the reception time and extend the receiving Doppler spectrum band width, thereby obtaining a high-resolution synthetic aperture radar even if an antenna of a comparatively narrow beam is used.
