    摘要: A stripline-type delay line has a plurality of rectangular sheet layers which are made from a dielectric material with a relative dielectric constant .di-elect cons.r of about 6.3, having magnesium oxide and silica as main components. One sheet layer is placed at the top, and the other layers are laminated thereunder in the following order: a sheet layer on which a first ground conductor is formed on its upper surface, a sheet layer on which a transmission line folded in a meander shape is formed on its upper surface, and a sheet layer on which a second ground conductor is formed on its upper surface. On side faces of the laminated dielectric and on adjacent portions of the upper and lower surfaces, an input terminal, an output terminal, and ground terminals are formed by printing, and then the dielectric is baked. The length A of the opposing line sections of said transmission line is preferably set such that the first peak frequency f of the delay time is within or above the frequency range of use, and substantially satisfies the following expression: ##EQU1## wherein Co indicates the speed of light, and .di-elect cons.r indicates the relative dielectric constant of said dielectric layers.

    摘要: A delay line is produced by firing a laminated body and terminals (an input terminal, an output terminal and grounding terminals) which are formed by printing or another method on the side faces, top and bottom surfaces of the laminated body. The laminated body has four dielectric rectangular sheet layers (dielectric constant .epsilon.r=approximately 6.3) containing mainly barium oxide, aluminum oxide and silica. The laminated body is formed by layering from top to bottom, in the order given, a first sheet layer, a second sheet layer which has a grounding conductor formed on its top surface, a third sheet layer which has a transmission line meanderingly formed on its top surface, and a fourth sheet layer which has another grounding conductor formed on its top surface. The transmission line has a meandering shape which defines a meander width, and has delay time peaks at respective frequencies, wherein the frequency fn at the n-th delay time peak substantially satisfies the formula: ##EQU1## where Co represents the speed of light; .epsilon.r, the dielectric constant of the dielectric layer; A, the meander width of the meanderingly formed transmission line; and n, a natural number. The transmission line may be formed by connecting in series a plurality of meanderingly formed transmission line segments having different respective meander widths. The plurality of transmission line segments may be formed opposite each other with the dielectric layer provided therebetween, the plurality of transmission line segments being connected to each other at ends thereof.

    摘要: The mirror drive for remote-controlled rear-view mirror assembly includes an air-tight container housing two motors to drive the horizontal and vertical turns of the mirror and which is composed of two synthetic resin-made casings which are closely attached to each other. Plural conductive plates which electrically connect terminals of the two motors to external terminals outside the airtight containers are previously buried in an insulative block with both ends there being exposed outside of the block. The insulative block covers the opening formed in the lateral wall of either of the casings and is secured to the lateral wall of the casing. Of the exposed ends of the plural conductive plates, those ones which are connected to the terminals of the motor are located inside the casings, while the other ends which are connected to the external connectors are led out through the opening in the casing.

    摘要: A connector 30 is integrated in a hermetic compressor 10. A flange block 48 is secured on the connector 30 by a screw 62. The connector 30 and the flange block 48 have through-holes 38 and 50, respectively, and a tube 54 is inserted into through-hole 50. A flange 58 is integrally formed in a peripheral surface of one end portion of the tube 54. Also, an elastic ring 60 is fitted near the flange 58. The flange 58 and the elastic ring 60 are positioned in enlarged diameter portions 40 and 42 formed in the connector 30 so that the ring 60 seals against the tube 54 and the connector 30. With this arrangement, simply by tightening the screw using a screwdriver, the tube can be securely connected with the container.
