Abstract: A heat treatment device and a method of manufacturing substrates capable of reducing the slippage of the substrates when the substrates are supported on support parts comprising plate-like members. The device comprises a support device having the support parts in contact with the substrates and a body part supporting the support parts. Each of the support parts comprises the plate-like members supporting the substrate so as not to come into contact with the peripheral edge portion of the substrate, and a non-contact part communication with the outside without coming into contact with the substrate is formed in the substrate placing surface of the support part. The overall opening area of the portion of the non-contact part communicating with the outside is 25 to 94% of the overall area of the substrate placing surface.

Abstract: A method for manufacturing a semiconductor device, includes forming a film on a substrate to be processed in a reaction furnace at a first temperature, unloading the substrate from the reaction furnace, and lowering a temperature in the reaction furnace to a second temperature which is lower than the first temperature, conducting a gas purge, using only an inert gas, in the reaction furnace after the substrate has been unloaded from the reaction furnace.

Abstract: In an electric vehicle capable of being regeneratively braked, driven wheels connected to and driven by a motor are connected to and capable of being regeneratively braked by a brake control unit. When the regenerative braking of the driven wheels is being conducted by the brake control unit, the gear-shifting of an automatic transmission by a motor/AT control unit is prohibited. Thus, the need for continuance or control of the regenerative braking during gear-shifting is eliminated, thereby preventing a reduction in braking force during the gear-shifting and the generation of a shock.

Abstract: In an electric vehicle capable of regenerative braking of wheels, a differential pressure regulating valve is interposed between a master cylinder for generating a hydraulic braking pressure by operation of a brake operating element and a brake cylinder for a driven wheel. In a first region in which an input hydraulic pressure into the differential pressure regulating valve is equal to or less than a predetermined value, an output hydraulic pressure from the differential pressure regulating valve is maintained at zero, and in a second region in which the input hydraulic pressure exceeds the predetermined value, the output hydraulic pressure is lower than the input hydraulic pressure by the predetermined value.

Abstract: A process and an apparatus for accurately locating and aligning dies on base plates is disclosed. The alignment of the dies is made by assembling a pair of the base plates in the form of a die set using jigs to be inserted into openings of the respective base plates for accurately aligning the base plate in vertically parallel relationship keeping space therebetween and for permitting the upper base plate to effect vertically reciprocal movement to accurately locate and align the dies with respect to the base plates. The apparatus comprises a pair of base plates and jigs for accurately aligning the base plates in vertically parallel relationship and for permitting the upper base plate to effect vertically reciprocal movement along the jigs to accurately locate and align the dies with respect to the base plates.

Abstract: A strut type suspension for a vehicle includes a mounting insulator rubber divided into two separate parts, one attached to the piston rod of a shock absorber, and a relatively more rigid one associated with both a spring coil telescoped about the shock absorber and a bumper.
