Title: Improvements in and relating to under-voltage time-element electro-responsive devices
IPC: H01H83/12
Filed: 1926-10-20
Abstract: 260,272. British Thomson-Houston Co., Ltd., (Assignees of Carpenter C. F., and Bohn, D. I.). Oct. 20, 1925, [Convention date]. Switches, partly electromagnetic; protective arrangements. -A thermal element 10, 12, 13 serves to introduce a time-delay into the action of an electromagnetically-operated controlling switch. When the voltage applied to the operating winding 15 is adequate, the armature 17 is attracted and an extension 20 presses a contact 12 on the thermal element 10 into engagement with a fixed contact 13. In the form shown applied to an A.C circuit, a current is induced, by the operating winding 15, in an auxiliary winding 21 connected directly to the thermal element or to a heating coil surrounding the element. Consequently, the element is heated up and bends so as to engage the fixed contact independently of the armature 17. If the armature falls back on a drop of voltage the thermal element maintains the contacts 12, 13 in engagement for a while. As applied to the novolt protection of an A.C motor, the motor is started by closing the switch 29 to supply voltage to the coil 15. This causes the closure of the contacts 12, 13 and when the starting button 26 is depressed the centre circuit of the starting switch 24 is completed. With a momentary drop of supply voltage the armature 17 may fall off but the contacts 12, 13 remain in engagement. With a prolonged fall in the voltage, the thermal element cools down sufficiently to cause the separation of the contacts thereby de-energizing the main switch.

Title: Fused junction semiconductor devices and method of making the same
IPC: H01L21/304
Filed: 1956-08-30
Abstract: 809,521. Semi-conductor devices. HUGHES AIRCRAFT CO. Aug. 30, 1956 [Sept. 2, 1955], No. 26576/56. Class 37. A junction device having a crystal body of one conductivity type and a regrown crystal region of the opposite conductivity type is formed with a pit, the walls and bottom of which are coated with such regrown crystal and which contains an alloy of a solvent metal and the material of the body. In practice a frustoconical pit is formed by sand-blasting in one face of a lapped monocrystalline wafer of N-type silicon, the 111 crystallographic planes of which lie in its faces. The wafer is then etched in a mixture of equal parts of nitric, hydrofluoric and acetic acids, and rinsed successively in distilled water and methyl alcohol. After drying it is heated to 800 C. in an evacuated chamber and aluminium evaporated on to the pitted face from a tungsten filament by the method described in Specification 807,959. Sufficient aluminium is deposited to fill the pit and to completely cover the remainder of the face so that on cooling at a controlled rate a recrystallized region 17 (Fig. 2) of P-type silicon is formed beneath a layer 16 of the eutectic alloy of silicon and aluminium. The eutectic alloy and P-type region is then removed from the surface of the wafer around the pit to give a device as shown in Fig. 3. After further etching an electrode is fixed to the remaining alloy area 16, an ohmic contact made to the N-type part of the wafer 10, and the device finally encapsulated. A transistor may be made by forming corresponding pits in opposite faces of the wafer and applying aluminium as described above first to one face and then to the other. A plurality of PN junction devices or junction transistors may be made by forming a a plurality of pits in one or both faces of a large silicon wafer, applying aluminium over the whole of one or both faces and then dividing the wafer into single units. Solvent metals such as gold, platinum, silver and tin containing aluminium, gallium, boron or indium as an acceptor impurity may be used in the above processes instead of aluminium. Junctions may also be made by applying gold, platinum, silver or tin, containing donor impurities such as phosphorus, antimony and arsenic to a suitable prepared P-type wafer. If germanium is used for the wafer instead of silicon lead is also a suitable solvent metal.
