A method for machining a groove in a sealing member and the edges of the groove. A tool 24 is formed with a top portion 24 having cutter sections 23A, each defining a cutting edge 23 for machining a groove in a scroll wall of a scroll member, and a tapered part 25 having cutter sections 26A, each defining a cutting edge 26 for bevelling the edges of the groove and the edges of the scroll wall. The groove 9 and edges 11 are simultaneously machined.

A thermoplastic water-curable composition which is excellent in mechanical properties, heat resistance, dimensional stability, and moldability and from which a mechanical part of a complicated shape can be produced: a molding formed from the thermoplastic water-curable composition; and a process for producing the molding The thermoplastic water-curable composition comprises: a thermoplastic resin which upon contact with water undergoes a cross-linking reaction and thus comes to have a high molecular weight, desirably one having silane groups in inner parts thereof and a water-curable composition, the amount of water-curable composition being desirably 200 to 700 parts by weight per 100 parts by weight of the resin The molding is formed from the thermoplastic water-curable composition. The process comprises molding the thermoplastic water-curable composition into a given shape and then bringing the molding into contact with water to age and cure it.

A microwave continuous heating apparatus is provided with a heating compartment having openings at its front and rear portions and a transfer device which carries a to-be-heated object held thereon through the heating compartment, and microwave electric power is irradiated onto the to-be-heated object that passes through the heating compartment to heat the same. Two microwave absorbing compartments, through which the to-be-heated object passes, are connected to the front and the rear portions of the heating compartment, respectively. A plurality of reflecting plates of metal which are spaced from each other in a forward-and-backward direction are transferred by the transfer device. The object to be heated is placed between two adjacent reflecting plates. The reflecting plates are placed on the transfer device so that at least one reflecting plate is positioned in each microwave absorbing compartment, at least during irradiation of microwaves into the heating compartment.

An automotive waterproof switch has a flange member integral to the switch. A screw is used to attach the switch to a car body. A protective cap is attached to the circumference of the flange member to cover the switch and the screw. There is an opening in the cap above the screw to access the screw for assembly. The edges of the opening comprise thin portions that are of a smaller diameter than the screw and retain the screw prior to final assembly.

The invention provides a bipolar transistor with improved performance. An insulation film comprising a silicon oxide film is formed by means of oxidation treatment on the side surface of an emitter aperture, and then an epitaxial layer comprised of SiGe is grown selectively in an aperture formed by removing a silicon nitride film so as to form under cut.

Automotive internal lights have a molded housing defining an elongate recess and bus bars which integrally include lamp holders secured within the molded housing and adapted to hold a lamp therebetween. The lamp holders have a base exposed to irradiate heat from said lamp. Connector terminals and an earth terminal are secured within said molded housing. The bus bars also integrally have spaced-apart fixed contacts secured within the molded housing so as to establish respective surfaces flush with the housing but exposed to said elongate recess. A slide switch is moveable longitudinally within the recess between at least first and second positions, and carries a generally U-shaped movable contact member which is adapted to contact the exposed surfaces of the fixed contacts so as to turn the lamp held by the lamp holder on and off, respectively. The housing includes notches formed in the recess opposite to the exposed surfaces of the fixed contacts. The slide switch includes a chamber, a ball accommodated within the chamber, and a spring extending between the moveable contact member and the ball. The spring thus urges the ball and moveable contact member away from each other and into forcible contact with the notches and the fixed contacts, respectively.

Automotive lighting systems include a casing which defines an interior space and a pair of shafts extending thereacross so as to establish adjacent first and second interior space regions. Lamps are positioned in respective ones of these adjacent first and second interior space regions and are covered by a respective pair of lenses. Each lens has proximal and distal ends and is connected pivotally at the proximal end thereof to a respective one of the shafts to allow for independent pivotal movements of the distal end between inoperative and operative positions. Push switches are operatively connected to respective ones of the lamps and positioned in respective ones of the first and second interior space regions in such a manner that the distal ends of each lens is in contact with a respective push switch. In such a manner, the push switches may be operated in response to the pivotal movements of the lenses between its inoperative and operative positions to thereby illuminate the lamps. Most preferably, the pair of shafts are positioned closely adjacent one another and extend across the casing at generally a central position thereof such that the proximal ends of the lenses are immediately adjacent one another with the lenses extending in opposite directions toward the distal ends thereof. The automotive lighting systems may be provided as a component part of a door switch circuit which responsively operates the lamps on opening of an automotive door.
