Abstract: 1475320 Semiconductor devices SONY CORP 18 June 1974 [21 June 1973] 26994/74 Heading H1K A thyristor comprising, in sequence and preferably in lateral relationship, n-type cathode region 1, respective p and n type first and second base regions 2, 3 and p type anode region 4 has a p type fifth region 5 isolated from the other p type regions 2, 4 by the n type region 3 and electrically connected to the cathode region 1, e.g. via cathode metallization 7K and p type zone 12/12<SP>1</SP>. This arrangement effectively places a third transistor 4/3/5 in the thyristor equivalent circuit, with its emitter-collector path connected between the anode and cathode, thereby improving the current-control capacity of the thyristor. A positive potential on gate 7G1 connected to first base region 2 switches the device on, while a negative potential on gate 7G1 switches it off. In a modification a p type sixth region (6) Fig. 3 (not shown) bearing a second gate electrode (7G2) is provided within the n type cathode region (1), effectively placing a fourth transistor (Tr 4 ) Fig. 4 (not shown) in the equivalent circuit. Switch-on is effected by a positive potential on first gate (G1) with second gate (G2) floating, and for switching off (G2) is shorted to the cathode (K) and a negative potential is applied to (G1). The operation of both embodiments is discussed in detail.

Title: Improvements in control systems for causing a part to move in response to displacements of another part
IPC: G05D3/14
Filed: 1945-10-16
Abstract: 627,969. Electric follow-up systems. ASSOCIATION DES OUVRIERS EN INSTRUMENTS DE PRECISION. Oct. 16, 1945, Nos. 27038 and 27039. Convention dates, March 20 and July 17. [Class 40 (i)] In a follow-up system, e.g. for the phantom ring of a gyro-compass, in which a pair of bolometer resistors in a bridge circuit are differentially cooled in accordance with relative displacement between the controlling and controlled members, it is arranged that the output of the bridge is not zero when the resistors are subjected to equal cooling actions. For instance, unequal values may be selected for the fixed arms of the bridge or a supplementary heater may be provided for one of the bolometer resistors or a supplementary source of current may be connected to any one of the bridge arms. As shown, Fig. 4, the bolometer resistors A, B on the phantom ring are cooled by an air jet from a nozzle 10 carried with the gyro element. The stream is divided into two portions by a partition 11 so as to affect one or other resistor to a greater extent according to the position of the partition. When the correcting motor is switched on by a relay and so exercises its maximum torque at once, it is arranged that the maximum cooling effect is exerted for small departures of the ring from the correct position. In this case the D.C. output of the bridge is of a pulsating character and a circuit, Fig. 8, involving a rectifier T and a time-constant circuit G, Z is used to eliminate the D.C. component. In an alternative arrangement in which the torque increases with the deflection, the bolometer resistors have a mask shaped as shown in Fig. 7 and the bridge is fed with A.C. and has its two fixed arms constituted by the primary of the input transformer of a thermionic amplifier feeding a reversible motor which controls the phantom ring through a further electrical transmission link, Fig. 16 (not shown).

Title: Improvements in means for starting, stopping & reversing internal combustion engines
IPC: F01L13/00
Filed: 1925-10-28
Abstract: 260,768. Rudqvist, C. A. Oct. 28, 1925. Starting prime movers.-An arrangement for starting, stopping, and reversing a Diesel or other engine M comprises a movable member 1, operative in successive steps to close a circuit through an ignition plug 55, switch on a starting motor 56, and release a fuel supply device 75, and means operative when the fuel supply device is inoperative to brake the engine. As shown, the member 1 is provided with a pointer 2 moving over a scale 3 and is pinned to the hub 7 of an element 8 rotatable on a tube 9 carried by a plate 10. An insulated contact 11 carried by one arm of the element 8 is adapted to bridge insulated contact rails 21, 22 carried by the plate 10 and connected. respectively to a battery B and to the ignition plug 55. The rails have a central recessed portion so that, in the " stop " position shown, they are not engaged by the contact 11; but in any position the contact can be held out of engagement by lifting and turning it so that a pin 17 engages the face 18 of the insulation. The other arm of the element 8 carries similar insulated contacts 32, 38 adapted to bridge pairs of contact rails 44, 44', 47, 47<1> for forward starting and 43, 43<1>, 46, 46<1> for backward starting. The rails 43, 47 are connected to one terminal and the rails 44, 46 to the other terminal of the motor the rails 43<1>, 44<1> to the positive terminal of the battery B, and the rails 46'. 47<1> to the negative battery terminal. Successive movements of the member 1 from the neutral position in either direction (1) close the ignition circuit by means of the contact 11 and the rails 21, 22, and connect one terminal of the motor to the battery by means of the contact 32 and rails 43, 43<1> or 44, 44<1>; (2) connect the other terminal of the motor to the battery by means of one of the contacts 38 and the rails 46, 46' or 47, 47<1>; and (3) release a pivoted catch normally holding the fuel pump out of action. In position (3) of the lever 1, a carn face on the member 8 displaces a member 97 carried by a spring 98 and normally serving to retain a member 30 in the depressed position. On the return of the handle 1 to neutral position by springs 60, the member 90 is projected upwards by a spring 94, and projections 89 on the ends of the member 90 prevent another operation of the starting lever unless a brake lever 68 is first operated. If the engine has failed to start, it is braked by means of the lever 68 before operating the starting lever afresh. A cam face on a sector 95 on the shaft 69 then depresses a member 93 on the spindle 92 of the member 90, which is held by the member 97, allowing a fresh operation of the starting lever.
