IPC: H01J23/40
Filed: 1990-02-07
Abstract: PURPOSE:To match the impedance of a slow-wave circuit and a coaxial junction plug by dividing an impedance matching cylindrical member into a slow-wave circuit side member facing between a metal cylinder and the slow-wave circuit and a coaxial Junction plug side member provided in the slow-wave circuit side member freely to move in the axial direction of the metal cylinder and facing to an inner conductor of the coaxial Junction plug. CONSTITUTION:An impedance matching cylindrical member 11 to be connected to a metal cylinder 1 is inserted into a part corresponding to a coaxial Junction plug in the metal cylinder 1. This cylindrical member 11 is divided into a slow-wave circuit side member 12 facing between the metal cylinder 1 and the slow-wave circuit 2 and a coaxial Junction plug side member 14 provided in this slow-wave circuit side member 12 freely to move in the axial direction of the metal cylinder 1 and facing to an inner conductor 6 of the coaxial junction plug. Consequently, the slow-wave circuit side member 12 and the coaxial Junction plug side member 14 of the impedance matching cylindrical member 11 can move in the metal cylinder 1 in parallel with each other separately. Since an insertion length L and a gap (g) can be separately adjusted with a pair of impedance matching cylindrical member, fine adjustment can be performed at the time of matching the impedance, and the impedance can be matched at more optimum value.

Title: Production of colored coated optical fiber
Inventor: NONAKA TAKESHI
IPC: C03C25/12
Filed: 1991-02-25
Abstract: PURPOSE:To prevent a colored layer from being simultaneously removed at the time of removing an integral coating layer by holding the surface of a primary coating layer in the uncured state and providing the colored layer on the outer periphery thereof. CONSTITUTION:The surface of the primary coating layer 2 of an optical fiber 1 is held in the uncured state and the colored layer 3 is provided on the outer periphery thereof. The method of holding the surface of the primary coating layer 2 in the uncured state is attained by, for example, curing the primary coating layer 2 in an atmosphere formed by incorporating oxygen into an inert gas at the time of curing this layer. The quantity of the oxygen to be incorporated into the inert gas is preferably 0.1 to 5%. The uncured state cannot be maintained if the quantity is <=0.1%. The uncured state is so poor that an appearance defect, etc., arise and such is undesirable in terms of reliability if the quantity is <=5%. The removal of the colored layer is prevented in this way at the time of removing the integral coating layer at the terminal in the case of joining coated tape optical fibers at the time of cable laying, etc.

Filed: 1984-02-20
Abstract: PURPOSE:To provide for more efficient utilization of engine power by forming a demand valve in such a construction as capable of making switching operation according to a pressure difference between the positions before and after a throttle placed in a steering circuit and to the flow supplied to a steering circuit through the demand valve. CONSTITUTION:A demand valve 6 supplying the fluid discharged from a working pump P2 and an auxiliary pump P3 to a working circuit 7 and a steering circuit 1 is formed in such a construction as to allow a switching operation according to a pressure difference between the positions before and after a throttle 12 placed in the steering circuit 1 and also to the flow supplied into the steering circuit 1 through the demand valve 6. By doing so, steering operation under very slow pump revolution will cause the fluid discharged from the working pump P2 and the auxiliary pump P3 to be supplied to the steering circuit 1, and with no steering operation, the flow will be directed to the working circuit 7 thus minimizing the pump capacity and providing for efficient use of the engine power for running.

Title: Lead frame for semiconductor device
Inventor: TSUKIIDE EIJI
IPC: H01L23/50
Filed: 1986-02-13
Abstract: PURPOSE:To improve reliability of devices by preventing ionic impurities from remaining on a semiconductor element mounting part hanging lead by thinning the thickness of a part of lead frame to extend a burr part of a resin mold. CONSTITUTION:Because a thick burr 4 of a resin mold 3 covers a semiconductor element mounting part hanging lead 7 and extends to an edge B of a tie bar 2, the distance between the edge B and a semiconductor element 5 becomes long. Accordingly, even if ionic impurities enter between the semiconductor element mounting part hanging lead 7 and the thick burr 4, the impurities are prevented from entering deeply. Also, as the thick burr 4 are cut later at a time of forming the lead, the ionic impurities are not left on the semiconductor element 5.
