摘要： In a compact wide-angle zoom lens having a two-group configuration composed of positive and negative lens groups, the first lens group is composed of G1A and G1B groups, while a stop is disposed between the G1A and G1B groups, thereby yielding a small lens thickness at its telephoto end and making it compact. The first lens group G1 is composed of G1A group comprising, successively from the object side, a negative lens having a meniscus form with a concave surface directed onto the object side and a positive lens having a meniscus form with a convex surface directed onto the object side, and G1B group having at least one biconvex lens. A shutter (stop) is disposed between the G1A and G1B groups, thereby allowing the first and second lens groups to be disposed close to each other at the telephoto end. Further, the zoom lens is set so as to satisfy the following conditional expressions: −0.6

摘要： A vehicle brake booster apparatus includes a housing, a movable wall positioned within the interior of the housing to divide the interior into a constant pressure chamber and a variable pressure chamber, a power piston connected to the movable wall for moving in response to movement of the movable wall, an axially movable input rod extending outwardly from the power piston for connection to a brake pedal, and an axially movable valve plunger mounted within the power piston and operatively connected to the input rod. A control valve is positioned within the power piston for controlling communication of the variable pressure chamber with atmospheric air. The control valve includes an air control valve and a vacuum control valve, with the air control valve including an air control seal arranged between the valve plunger and a valve body portion of the control valve. The air control seal has a radially outwardly located peripheral portion which possesses an elasticity that is greater than the elasticity of a radially inwardly located portion of the air control seal to thereby provide an effective air-tight seal.

摘要： In order to prevent expansion of a metal sheath which is heat treated in order to form an oxide high-temperature superconductor therein, the heat treatment temperature is held at a certain level in an intermediate stage of temperature rising in a step of heat treating the metal sheath after filling raw material for an oxide high-temperature superconductor into the metal sheath. After the heat treatment temperature is thus held at the certain level, the metal sheath is again heated to a target temperature. Preferably, the heat treatment temperature is held at a level which is selected in a range of at least 500.degree. C. and not more than 750.degree. C.

摘要： This invention provides a pressure switch and a method of manufacture thereof, which allow the air vent hole to be formed very small in diameter so that the engine oil can be reliably prevented from flowing out through this air vent hole.The reduced diameter portion of the air vent hole 13 is formed in the following steps during the process of resin-molding the insulating cap 3 of the pressure switch 1. After the air vent hole 13 having the outwardly projecting portion 14 is formed, the recessed portion 16 of the jig 17 is placed in contact with the circumferential surface of the projecting portion 14 of the air vent hole 13. The jig 17 is pressed against the projecting portion 14 of the air vent hole 13 with a specified pressure to deform the projecting portion 14 and thereby reduce the inner diameter of the air vent hole 13 at the end.
