As shown rotor 5 has a recess 5b so that the capacitance changes on its rotation but it may have any like functioning cut-away portion. Slot 5alpha is provided for engagement with a screw-driver, or aperture 7e may be closed by a plug having a projection mating with slot 5alpha, the plug being rotatable by a screwdriver (Fig. 8, not shown). The stator electrode may be moulded with support 2 so that their surfaces are flush, and the electrode may have projections for keying it to the support. In an alternative embodiment (Figures 9 and 10, not shown) the contact portion of the rotor lead is separate from the spring. Support 2 may be integral with base 1. Casing 7 and base 1 may have mating projections and grooves and may be secured together by adhesive or by ultrasonic welding.

摘要： A cast ceramic body with >=1 through hole and two electrodes, the casting consisting of ZnO/TiO semiconductor material. It can be a rectangular block with through holes or tubes of cylindrical, triangular or polygonal section used individually or together. The casting or substrate is made by sintering at 900-1450 degrees C. a mixt. of 50-99 mol.% ZnO, 1-50 mol.% TiO2, with, if necessary, 10 mol.% of the oxides of Ni, V, Cr, Mn, Fe, Co, Cu, Ag, Be, B, Cd, Mg, Al, Sn, Sb, Bi, Nb, Mo, Zr, Ta, W, Y, La or other rare earths, Ca, Sr, Ba, Pb, Th, and/or other metal oxides. The oxides are wet ball milled, mixed with a suitable binder and cast, then sintered. An example cites a cast tube, 3 mm. dia. bore 1.3 mm. length 98 mm. and radius of curvature 20 mm. Using this tube in a secondary electron multiplier the amplification obtd. was 107-109 and the tube can be used at temps. >150 degrees C.

摘要： 1516821 Variable resistors MURATA MFG CO Ltd 15 Feb 1977 [2 March 1976] 06263/77 Heading HIS A variable resistor comprises an insulating rotor 3, having a resistive track 3b on one face electrically connected at 3f to at least one conductive layer 3d on the other face, the resistive track being contacted by the contact 4d of a fixed terminal 4 and the conductive layer (5) being engaged by at least one further fixed terminal 2 mounted on an insulating base, plate 1. As shown, a terminal 2 fits in a groove 1b, rotor 3 fits in a recess la under a projection 1d, and terminal 4 fits on a projection 1e of base plate 1. A slot 3c in the rotor permits adjustment thereof by a screwdriver. In a modification (Figs. 8-10, not shown) two concentric conductive layers are provided on face 3a1, respectively connected to opposite ends of the resistive track, the conductive layers each being engaged by a respective fixed terminal (2 1 A, 2 1 B). The resistor may be provided with a cover 5 having a hole 5a aligned with screwdriver slot 3c. To prevent entry of dust the hole may be surrounded by a sleeve (5 1 b, Fig. 5, not shown), or be fitted with a plug member 6.
