Abstract: In a drive shaft press-fitting device, when a collet chuck (clamp) is moved backward by a linear motion means, the end part of the collet chuck closes by collaboration of a tapered surface of the collet chuck and an engagement part of a sleeve, and thereby the collet chuck holds an external thread part of the drive shaft. When the collet chuck is further moved backward by the linear motion means, the drive shaft is drawn out of the axle hub by the collet chuck, and thereby the drive shaft is pressed into the axle hub. After press-fitting, when the collet chuck is moved forward by the linear motion means, the collet chuck opens to be away from the external thread part of the drive shaft by a biasing means.

Abstract: There is provided an integrated electric compressor having a circuit configuration capable of decreasing the size thereof while restraining current ripples. In an inverter of the electric compressor, by providing a capacitor 13 and a reactor 14 between a power source and an inverter board 12, the ripples of a driving voltage is restrained, and a motor can be driven with high efficiency and the size of a housing can be decreased. Further, by connecting the capacitor 13 and the reactor 14 to a power board 16 by using a bus bar 23, the voltage ripple restraining effect is further increased, and the capacitor 13 and the reactor 14 are unitized integrally by the bus bar 23 to improve the assembling workability of the power board 16.

Abstract: A method of forming trench isolation comprising the steps of: burying a plurality of trenches formed in a substrate with a burying material and simultaneously forming a burying material layer on protrusive regions between adjacent trenches, by use of a process for concurrently executing vapor phase growth and etching; conducting an isotropic etching in such a manner as to leave the burying material layer on the protrusive region; and removing the remaining burying material layer by a CMP process for planarization.
