Title: Improvements in and relating to electric switches
IPC: H01H73/38
Filed: 1922-10-28
Abstract: 187,993. British Thomson - Houston Co., Ltd., (Assignees of Tritle, J. F.). Oct. 28, 1921, [Convention date]. Automatic circuit-breakers in which the contact member is released from a retaining electromagnet by the de-magnetizing effect of a straight conductor carrying the load and passing through the gap in the electromagnet as described in Specification 125,279 are provided with loose handle arrangements. The handle 23 or the electromagnet 24 causes the roller 22 to move the contact-member 13 in the closing direction against the action of the spring 14 while holding the contact 10 out of engagement with the fixed contact 1L until the handle is released, whereupon the spring 14 rotates the contact-member in the opposite direction about the pivot 19 on the pivoted armature lever 17 and completes the circuit. The contact-member is supported at its lower end by a strap connector 30 which carries the load and an overload tends to straighten out, automatically, thereby assisting the breaking movement when the de-magnetization on the armature 16, due to the conductor 29, has caused the release of the armature on overload. The intermediate position is shown in Fig. 3, in which the armature is held to the electromagnet, but the switch is not closed until the handle has been released or the operating electromagnet de-energized whereupon the contact-member swings round under the action of the spring 14 and, free of the roller 22, moves into the closed position shown in Fig. 4. On overload, the members 13, 14 move as a whole back to the off position shown in Fig. 1. A weight 39 is placed on the lower end of the contact-member to increase its moment of inertia below the pivot and ensure the correct relative movement of the members 13, 14. In the final closing movement, the lever 17 operates contacts to open the circuit of the operating coil 24.

Abstract: 1,010,803. Latches. WILMOT-BREEDEN Ltd. Aug. 15, 1962 [Aug. 21, 1961], No. 30022/61. Heading E2A. A spring-loaded door latch for the glove compartment of a car has leaf spring means arranged to perform the dual function of a throw-out spring to open the door and retaining means for holding the latch in unlatched position until the door is again closed. Three embodiments are described, two with latch levers and one with a sliding bolt. The first embodiment (Figs. 2 and 3) employs U-shaped spring means 9 and a catch lever 1 which upon being withdrawn from the position of Fig. 2 to that of Fig. 3 permits the arm 15 of spring 9 to act against the fixed casing 7 to open the door. The lifting of arm 4 of lever 1 flexes arm 10 of spring 9 to return lever 1, but this is prevented by the end 14-of spring arm 15 until the door is again closed. The embodiment of Figs. 5 and 7 is similar in construction except that the throw-out spring is a single arm 14 riveted to the casing at 22. In this case, when the door catch is released a torsion spring 23 is stressed to hold the end 5 of the lever 1 against a step 16 on the spring arm 14 until the door is again closed. The catch also employs a cylinder lock 29 which when rotated from the full line position to the chain dotted prevents the lever 1 from being lifted to open the door. The embodiment of Figs. 9 and 10 employs a sliding bolt 34 which latches under the influence of a coiled spring 37. Upon the knob 36 being slid downwardly, a leaf spring 14 throws the door open and the bolt 34 is held back in inoperative position by a step 16 as in the above-mentioned second embodiment.

Title: Method of making p-n junction
IPC: C30B19/08
Filed: 1970-06-22
Abstract: 1286753 Epitaxial growth SHARP KK 22 June 1970 [20 June 1969 (2)] 30220/70 Heading BIS [Also in Divisions H1 and C4] The conductivity-type imparted to a liquidphase-epitaxially grown semiconductor material by an amphoteric dopant included in the malt from which the material is grown is determined by the rate at which the malt is allowed to cool. The invention is based upon the discovery that the transition temperature at which the deposited material becomes p type (low crystallisation temperature range) rather than n type (higher crystallisation temperature range) decreases as the cooling rate of the malt increases. Thus in Fig. 3 curve A shows a cooling programme whereby firstly a p type layer and subsequently an n type layer are deposited on a substrate, while for curve B the converse is true. The substrate may be of p, n or i type material. Multi-layer structures (e.g. up to 13 layers of alternating conductivity types) may be formed by successively increasing and decreasing the cooling rate of the malt. A particular example comprises a pn pn light emitting GaAs diode in which the amphoteric dopant is Si, and if the cooling programme is modified to omit the upper p type deposition an npn GaAs transistor may be formed. The malt in these cases comprises Ga containing As and Si. A light emitting diode having only a single pn junction may be manufactured using the programme shown in Fig. 8(B), in which first n type and then p type GaAs is grown by liquid phase epitaxy on an n type GaAs wafer. In this case the temperature is initially raised very slowly after the malt covers the wafer, then very rapid cooling takes place at a rate sufficient to ensure that only n type material precipitates. The cooling rate is then reduced and held constant as firstly n type material and subsequently, when the malt temperature falls below the transition temperature, p type material, are deposited. Alternative semiconductor materials are GaP, InP, GaSb, GaN, AlSb, (GaAl)As, Ga(AsP) or (GaAl)P. Ge and Sn are referred to as alternative amphoteric dopants.
