IPC: H01H35/34
Filed: 1991-06-04
Granted: 1995-06-13
Abstract: A fluid-tight electrical pressure switch for hydraulic or pneumatic circuits, comprising a cylindrical hollow body (2) with a tubular union (3) for connection to a pressure circuit and blades (7) for connection to an electrical indicator circuit. Inside the body (2) are a pair of fixed contacts (16) connected to the blades (7) and a movable contact (17) adapted to engage the fixed contacts (16). Thrust means (18) seek to maintain the movable contact (17) in engagement with the fixed contacts (16). An elastic membrane (8) separates sealingly the cavity in the body (2) from the tubular union (3) and controls the displacement of the movable contact (17) when a predetermined pressure is reached. A locking member (10) locks the peripheral edge (8a) of the membrane (8) in relation to the body (2). Interposed between the membrane (8) and the movable contact (17) is a cap-shaped elastic member (9) adapted to change shape with a snap action when a pressure threshold value is attained. The locking member (10) is locked either by the folding of an end edge (5) or by the member (10) being screwed into the body (2). <IMAGE>

Title: Apparatus for manipulating a plasma
IPC: H05H1/14
Filed: 1959-01-01
Abstract: 860,840. Pulse-producing circuits. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 1, 1959 [Feb. 13, 1958], No. 37/59. Class 40 (6). [Also in Group XL (a)] A pulse circuit for a thermonuclear reactor comprising an elongated vacuum chamber surrounded by a solenoid formed of a number of solenoidal segments connected in series, comprises programming circuitry for supplying electrical energy to the segments in succession whilst simultaneously energizing the remaining segments that have not had said electrical energy applied to them, thereby providing in the chamber a magnetic field with a reflector field closure moving along the axis of the chamber. Fig. 2 shows a circuit which may be used for energizing the solenoidal segments 17-23, of which each except the centre one is connected to a capacitor bank 28-33 through an ignitron 36-41. A central capacitor bank, which may be divided into two sub-banks 43, 44, is connected to the junctions between adjacent segments through ignitrons 47-52. Each segment is shunted by an ignitron 53-58 which is triggered by a peak current detector such as a diode 61-67. Diodes 61-64 are connected in series with transformers, the secondaries of which are connected to trigger circuits 72-75. Capacitor banks 28-33 and 43, 44 may be charged from a power source through a programmed switch, and ignitrons 36, 37, 47, 48 fired from a pulse generator. When ignitrons 36, 37 are fired, capacitor banks 28, 29 discharge through segments 17, 18 whilst at the same time, due to the firing of ignitrons 47, 48, capacitor banks 43, 44 begin to discharge through the remaining segments. When the current through segments 17, 18 reaches its peak the voltage reverses and causes ignitrons 53, 54 to fire, and, through trigger circuits 72, 73, causes ignitrons 38, 39, 49, 50 to fire. When ignitrons 38, 39 fire, capacitor banks 30, 31 discharge through segments 19, 20 and the simultaneous firing of ignitrons 49, 50 cause capacitor banks 43, 44 to continue discharging through segments 21- 23. Similarly, when the current through segments 19, 20 reaches its peak, ignitrons 55, 56 fire and, through trigger circuits 74, 75, ignitrons 40, 41, 51, 52 also fire causing capacitor banks 32, 33 to discharge through segments 21, 22 and capacitor banks 43, 44 to discharge through segment 23. The effect of this is to produce a magnetic field through the solenoid which is constant in the middle and rises to peaks at each end, and the peaks move towards each other in two steps. Short-circuited coils 83-85 may be inductively coupled to the three central segments 21-23 and serve to retard the decay of the magnetic field. In a modified circuit, Fig. 4 (not shown), electrical overlap of the segments is achieved by connecting a further series of ignitrons and capacitor banks between the mid-points of adjacent segments.

IPC: H01L23/473
Filed: 1994-01-04
Abstract: PURPOSE:To lessen the temperature difference between chips by arranging the fins of a cooling member attached to the top of a housing so that it may cross the second fin of the housing at a proper angle. CONSTITUTION:A water-cooling fin 13 attached to the top of a housing 9 is arranged so that it may cross the fin 8 of the housing 9 at right angles. Accordingly, the heat conducted from the housing 9 to a water-cooling jacket 12 widens in parallel with the fin 8 on the side of housing 9, and widens in vertical direction to the fin 8 on the housing side 9 with the water-cooling jacket 12. Hereby, the heat generation quantity of a plurality of LSI chips are different, and in case that the fellow LSI chips are positioned in vertical direction to the fin 8, the heat of the chip high in heat generation quantity is conducted to the side of a chip lower in calorific value through the housing 9 and each fin 8 and 13 of the water-cooling jacket 12, and the temperature difference between LSI chips becomes small.

Abstract: 431,145. Calcium carbonate; caustic soda ; slaking lime. PITTSBURGH PLATE GLASS CO., 2200, Grant Building, Pittsburgh, U.S.A.-(Assignees of Boss, A. E., Allen, E. M., and Lynn, G.) Jan. 2, 1934, No. 148. Convention date, Jan. 21, 1933. [Classes 1 (ii) and 1 (iii)] Finely divided calcium carbonate is obtained by reacting milk of lime with alkali carbonate at an initial temperature between 25 and 40‹ C., with vigorous agitation of the reaction mixture. In the absence of agitation, finely dispersed milk of lime must be used, and this may be obtained by slaking burnt lime by adding it to hot water at such a rate that the mixture remains near the boiling point, vigorously agitating the mixture, and removing coarse particles from the product. Excess alkali carbonate is preferably used, either as soda ash or in solution, it being desirable that the concentration of calcium carbonate obtained should be between 0À5 and 1À5 pounds per gallon. If during reaction, a gel is formed, stirring is continued until it disappears. The calcium carbonate is washed free from caustic alkali, and either dried direct or first treated as a slurry with a coating agent, which may be butyl, glycol, or glyceryl stearate, the mixed esters found in lard, lard oil, corn oil, sperm oil, tallow, or cocoanut oil, compounds of the higher fatty acids with organic bases such as mono-, di-, or tri-ethanol amine or butyl amine, or natural and synthetic organic waxes and resins such as halogenated paraffins or naphthalenes, coal tar resins, vinyl resins, or petroleum by-product resin from oilcracking processes.
