Abstract: PURPOSE:To promote the easiness or the like of machining, by forming a cavity part, having ruggedness, in the reverse of a surface side plate in a ceramics- made impeller and a double-layer structure filling this cavity part with resin and/or metal dust. CONSTITUTION:In the case of a ceramics-made impeller, a cavity part, having ruggedness, is formed in the reverse of a surface side plate of the impeller being filled with resin and/or metal dust, and a double-layer structure is formed.

IPC: H02P7/28
Filed: 1980-06-04
Abstract: PURPOSE: To eliminate the sudden change of torque and to improve the comfortableness of riding at the time when an electric vehicle is starting by a method wherein the reference value to be used for comparison in the phase shifter which outputs a signal of current continuity rate is changed in accordance with the variation of a chopping frequency.  
     CONSTITUTION: The comparison amplifier 1 outputs the voltage signal VPP in proportion to the deviation between a main motor current feedback value I af  and a main motor current command value I ap . Also, a phase shifter 2 outputs ON and OFF signals when the level of the voltage signal VPP became larger than the level of the integrator output which is repeating an integral control action for each reset pulse fRP to be outputted from an oscillator 3. When the chopping frequency is changed from fO/2 to fO, a chopping frequency command fV is added to the comparison amplifier 1 and the voltage signal VPP becomes one half. Through these procedures, no change in the current continuity rate is created at point before and after the change of the chopping frequency and the comfortableness of riding at the starting time can be improved.

Abstract: PROBLEM TO BE SOLVED: To improve a welding quality by detection the fluctuation of the surface of a molten pool just under an arc, which is generated by the fluctuation of a root gap, from welding voltage or current waveform, using a high speed rotation arc sensor, and controlling properly the welding condition. SOLUTION: To the voltage waveform VTref of the proper welding condition to a standard root gap Gref, the waveform area deviation ΔSG of a voltage waveform VT at the time of welding with an actual root gap G, is calculated from a ΔSG-G characteristics curve which has been found in advance. Successively, from weld bead shape, height, leg length, etc., under the proper welding condition to G=Gref, the allowable range of G+Δg1, -Δg2 are determined. The allowable range of detected ΔSG, i.e., ΔS1, -ΔS2 is found from the ΔSG-G characteristic curve. When the ΔSG is within the allowable range, welding is performed with the welding condition as it is. Also, when the ΔSG has reached the allowable range, the welding condition is changed to the proper welding condition which has been found in advance to G=Gref+Δg1 (or -Δg2).

Abstract: PURPOSE:To avoid short-circuit caused by build-up and the like of conductive material such as solder at the time of assembly by a method wherein an insulating film is formed on the part of a semiconductor element where a short-circuit is created by the adhesion of the conductive material so as not to expose that part. CONSTITUTION:Element isolation mesa trenches 4 are so formed by a method such as etching in a semiconductor wafer as to have the widths larger at the laser beam emitting edge parts than at the center parts. Then bars are formed by cleaving and the edge 1a is coated with SiO2, Al2O3 or the like. At that time, the side surface 1b are also coated with SiO2, Al2O3 or the like and insulating films 3 are formed of those materials. After the respective elements are isolated by the element isolation mesa trenches 4, each element is mounted on a submount 5 with solder 6 in the form of junction-down to obtain a semiconductor device. By forming the insulating film 3 like this, the short-circuit of a p-n junction 2 can be avoided even if the solder 6 adheres to the side surface 1b by protrusion or build-up.
