Title: Semi-conductor arrangements enclosed in housings
IPC: H01L23/48
Filed: 1962-06-14
Abstract: 970,895. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. June 14, 1962 [July 12, 1961], No. 22988/62. Heading H1K. A semi-conductor device consists of a waferform, substantially monocrystalline, semi-conductor body fixed to a carrier plate and held by spring pressure between a cooling member and a metal contact. As shown, a stack consisting of a molybdenum plate 4, an aluminium foil, a wafer 5 of P-type silicon and a gold foil 6 containing antimony, is pressed into graphite powder and heated underpressure to form an alloyed PN junction rectifier. A copper cooling member 2 has a projection 2a on which a layer 7 of silver and the plate 4 are placed. A copper pin 8, a ring 9 and a molybdenum disc 10 are soldered together and the lower face of disc 10 is plated with silver. Steel washers 11, 13, mica washer 12 and dished springs 14, 15, 16 are placed on the pin and a bell-shaped retaining member 17 is placed over them and attached to member 2. A bell-shaped housing consisting of steel or nickel-cobalt-iron alloy, parts 18, 20, ceramic part 19 and copper cap 21, into which pin 8 is pushed, are soldered together and fixed to member 2. A connecting wire 22 is pushed into cap 21 and fixed by pinching cap 21 round it. A rectifier of opposite polarity may be made by applying a silver foil and a molybdenum disc to the projection 2a and placing the electrode 6 of the semi-conductor element on this. Plate 4 is made smaller and a silver foil is inserted between it and pin 8 which does not carry the disc 10 in this embodiment. An insulating centring ring may be placed round plate 4. Rectifiers of opposite polarities may thus be obtained, for example for use in threephase bridge arrangements using a common cooling installation. The semi-conductor body may also be of germanium with alloyed-in electrodes of indium and lead-arsenic. The carrier plate may be of high-alloy steel with a similar coefficient of expansion to that of the semi-conductor body.

Abstract: 240,158. Matabon, J. L., and Foucault, C. M. Sept. 20, 1924, [Convention date]. Alternating-current commutator and induction machines.-The power factor of an asynchronous machine o, p, Fig. 3, is regulated by an exciter having on its rotor a normal primary slip-ring winding g, Fig. 2, and a separate commutator or " primary exciter " winding h connected to its stator or " secondary motor and compensator " winding i and to the secondary winding p of the machine under regulation, starting resistances being inserted in the conductor connecting the commutator brushes to the secondary windings i, p of the exciter and asynchronous machine. The exciter is not mechanically coupled to the asynchronous machine. The rings of the winding g are connected to the mains in parallel with the primary coil o of the regulated machine. At starting, the switches are placed on the dead terminals k, l and movement in the direction of the arrows brings up both machines as induction motors. Further movement on to the studs n, m establishes connection between the exciting commutator winding h and the secondary windings i,. p of the exciter and main machines respectively, giving compensation in both machines. The degree of compensation is determined by the position of the brushes on the commutator. Specifications 22932/09 and 213,272 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that an exciting machine as described may be arranged as a small self-starting asynchronous compensator of which no mechanical power will be demanded and suitable for small motors with short-circuited rotors. This subject-matter does not appear in the Specification as accepted.

[Class 100 (ii).] Addressing and like machines; stopping, starting, tripping, and like arrangements.-An addressing or like series-printing machine is provided with electrical control-mechanism co-operating with tabs &c. on the printing-devices to control the impression and the main drive, the two controlling operations being adapted to function separately or simultaneously and being actuated from the same or from different tabs. As shown applied to a machine of the type in which address-plates 7 are moved along a guideway 5 into printing position beneath a platen 8 carried by a rocking arm 9, - the movement of the platen and the machine drive are controlled by means of electromagnets 57, 44 respectively, the energization of the magnets being controlled by tabs T on the plates 7. The magnet 57 is adapted to attract an armature 55 so as to release a dog 53 fixed to a shaft 48 which turns clockwise end removes a roller arm 49 from the path of a block 51 on the end of a reciprocating .bar 14 whereby, during the forward stroke of the bar, a notch 13 therein drops into engagement with a pin 12 on the arm 9 which performs.a printing operation; during the return stroke, the bar 14 returns the arm 49 to normal position, and a lever 59 holds down the dog 53 pending the return of the armature 55. The bar 14 ism pivoted to a rocker 15 actuated bv a rod 19 corinected to a crank 21 fixed on a pulley 23 rotated from a main shaft 26 driven by a rotary pulley 27 carrying a pivoted pawl 32 engaging a notch in a collar 29 fixed on the shaft 26. The magnet 44 when energized attracts an armature 40 so as to release a bell crank 35 which is moved by a spring 46 into the path of the pawl 32 whereby the drive is disconnected; the crank 35 is returned to normal position manually by means of a rod 47. The impression is controlled by a number of parallel circuits in series with a battery 66 and the magnet 57, each circuit including one of a number of contacts a<2> .. a<5> and a corresponding control switch c<2> .. c<5>, and each contact being closed by a pivoted detector 62 when engaged by a tab T. The main drive is controlled by an additional contact a<1> arranged in series with the battery 66 and with the magnet 44. In a modification, the contact a<1> is arranged, in addition, in a circuit which is in parallel with the other'circuits and includes a switch, whereby the contact may, if desired, control the impression in addition to the drive. In a further modification, each. of the contacts a<1> .. a<5> is, in addition, connected through a switch to the magnet 44 so that'any one of the contacts may be used for controlling either the impression or the drive. According to the Provisional Specification, the control mechanism may be mechanical instead of electrical.

The liquid pressure in the high pressure line 5 (or 7) acts through a line 23 (or 22) on a servo 19 (or 20) which actuates the bypass valve 17 (or 16) to effect a by-pass of the flow-dividing valve in the low pressure line 7 (or 5). Both flow dividing valves 14, 15 may be by-passed by supplying pressure liquid through a manually controlled valve 27 to servomotors 18a, 19a which actuate by by-pass valves 16, 17. Each flow dividing valve and its by-pass valve may be formed in a single block, Fig. 4, in which a supply duct 8 is connected through orifices 7c to chambers 7d at each end of the flow dividing valve spool 37. The valve spool 37 meters flow to the ducts 7. The by-pass valve comprises a valve spool 39 which is normally biased by a spring 44 to the position shown in which it blocks direct communication between the ducts 7, 8. When pressure liquid is supplied to the servomotor 19 or 19a the valve spool 39 moves left to connect the supply duct 8 directly to the duct 7. The motors 1 may drive wheels on opposite sides of the vehicle.

A spring coupling, transmitting drive to aeroplane instruments &c., comprises a continuously rotating driving shaft 2 carrying a disc 1 having a tongue 5 similar to a tongue 4 on a disc 6 fast with an intermittently rotating driven shaft 11, a stressed loop spring 7 biasing the tongues &c. to the relative position shown. A pawl 9 on a stationary support is spring biased to slide on the periphery of the disc 1. A tongue 8 on the driven disc 6 is centred in a recess 3 in the periphery of the disc 1 when the shafts 1, 11 coincide angularly. The tongue 8 is engaged by the pawl 9 when it enters the recess 3, and the rotation of the driven shaft 10 is thus arrested. The driving shaft 2 continuing to turn, the disc 1 rotates against the bias of the spring 7, until the pawl 9 is cammed outwards by one of the sloped ends of the recess 3 and released from the tongue 8. The disc 6 and driven shaft 10 are then accelerated by the energy stored in the spring 7, to catch up wth the shaft 1 &c. and restore the original relative angular positions of the driving and driven shafts. More than one recess 3 may be provided in the periphery of the disc 1.
