IPC: E02F3/43
Filed: 1988-07-04
Abstract: PURPOSE:To improve the linear locus accuracy by keeping a constant boom transmission function and a constant arm transmission function and therefore eliminating the interference between the X and Y coordinates. CONSTITUTION:The target value arithmetic means 15 and 16 calculate the target rotational speed and angle of a boom and an arm respectively for the shift of an arm tip point to a commanded position based on the position commanded by a position commanding means 10 and the present positions obtained by the present position detecting means 13 and 14. Then an arm drive means 18 and a boom drive means 17 control the arm and boom cylinders respectively based on the target values obtained by the means 15 and 16. An arm transmission function compensating means 100 keeps both arm and boom transmission functions at each constant value. Thus both transmission functions are kept constant and equal to each other and the X and Y coordinate systems are completely separated from each other. As a result, the linear carving accuracy is improved for a sloping surface.

Title: Manufacture of semiconductor device
Inventor: YONEDA TADANAKA
IPC: H01L21/76
Filed: 1987-07-03
Abstract: PURPOSE:To prevent the increase of a leakage of electricity due to concentration of electric fields in a low current region by making the height of an insulating film in an isolation region higher than that of the surface of an element formation region and further, by forming edge parts of the element formation region at an obtuse angle. CONSTITUTION:Grooves 34 are formed by etching a p-type silicon substrate 30 where SiO2 and polycrystal silicon films 31 and 32 are formed. Then a SiO2 film 35 is formed by treating with heat in an oxidized atmosphere. In such a case, bird's beaks develop below the polycrystal silicon films 32 and thick SiO2 films 36 are formed. The SiO2 films 37 are formed with a thermal decomposition process so as to fill up the grooves 34. And then a photoresist film is coated and the SiO2 films 37 are etched excessively to expose the polycrystal silicon film 32. And then, a gate oxide film 38 and a gate electrode 39 are formed after removing the polycrystal silicon film 32 and SiO2 film 31. As edge parts 40 of a MOS transistor formed in this way have smoothed angular parts, the increase of a leakage of electricity due to concentration of electric fields does not develop.

Abstract: PURPOSE:To realize the extremely slow speed operation of an actuator easily by changing the set value of a pressure difference between the discharge pressure of a hydraulic pump and the load pressure of the actuator generated by an outside operation based on the instruction of a pressure difference change instruction means. CONSTITUTION:When an usual operation is set by the operation of an instruction device 22, a control force corresponding to a memorized pressure difference correction value is outputted to a control force giving device 25 by a controller 24, which controls by a control valve 18 the discharge amount of a hydraulic pump 1 so that the pressure difference between the discharge pressure of the hydraulic pump 1 and the load pressure of an actuator 2 may become the set value determined by the resultant of a spring 12 force and the control force. While, when the instruction device 22 is not operated due to the intention of a special work requiring a delicate operation, an instruction signal is not inputted to the controller 24. Therefore, the discharge amount of the hydraulic pump 1 is controlled so that it be becomes the pressure difference matching with the spring 12 force, and accordingly a comparatively small flow amount is supplied from the hydraulic pump 1 to the actuator 2. Thus, the work requiring the delicate operation can be performed easily.

Title: Capsule redashing into atmosphere
Inventor: KUROSAKI RYUJIRO
IPC: B64G1/58
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To block heat transmission from a heated air stream behind impulse waves to a surface of a capsule body for preventing the capsule body from wear and internal overheat by constituting the capsule body having a cooling tank therein to guide gas through a relief valve to a gas jet on the capsule surface and eject the gas to the outer surface as it is. SOLUTION: In a capsule to redash into the atmosphere from a track around the earth, the capsule 1 has a cooling gas tank 5 in the body. When the capsule dashes into the atmosphere, a relief valve 6 is opened to eject cooling gas from a gas jet 7. Since the gas forms a gas stream 8 between a high temperature air stream 4 and the capsule 1, a temperature in the boundary layer is lowered. Also, the temperature gradient between the boundary layer and the surface of the capsule 1 becomes gentle and an inflow amount of heat is reduced, so that heat inflow from high temperature air stream by air heating can be reduced.

Title: Fuel assembly, fuel channel box and production thereof
Inventor: NAKAJIMA JUNJIRO
IPC: G21C3/30
Filed: 1994-07-20
Abstract: PURPOSE:To ensure the thermal margin of a fuel rod by varying the heat treatment of a channel box made of a Zr based alloy in the longitudinal direction, and varying the crystal orientation of alpha-phase Zr in the longitudinal direction, thereby suppressing the bending deformation caused by irradiation growth and reducing the bypass flow rate between the channel box and a lower tie plate. CONSTITUTION:Two sets of U-shaped components are combined and the butting part is welded to produce a rectangular pipe and the end D thereof is set on the lower tie plate side. Heat treatment is started from the end D by high frequency heating and water, passed through a high frequency induction heating coil 22 and heated up to the beta-phase temperature range, is sprayed through a nozzle 23. Output of a high frequency transmitter 24 is controlled such that the region within about 15cm from the end D is heated up to the (alpha+beta) phase temperature range while the remaining region of 385 cm is heated up to the beta-phase temperature range. Consequently, the bending deformation is reduced significantly in the vicinity of the end D and the gap is eliminated between the channel box and the lower tie plate thus preventing leakage of cooling water.
