Title: Semi-conductor device with negative resistance characteristics at extreme low temperatures
IPC: H01L31/00
Filed: 1963-03-19
Abstract: 1,021,577. Semi-conductor devices. HITACHI Ltd. March 19, 1963 [March 24, 1962], No. 10900/63. Heading H1K. A semi-conductor device exhibiting negative resistance characteristics of low temperatures comprises a semiconductor base having a deep trap level formed therein. With this arrangement the electrons excited from the valence band 1 (Fig. 4), to the conduction band 2 by light radiation falling on the device which do not fall into the donor level 3 immediately fall through the deep trap level 5 and recombine with the previously formed holes in the valence band so that the electron density in the donor level 3 exceeds that in the conduction band 2 thus increasing the critical field strength corresponding to the breakdown voltage as compared with devices not subjected to light radiation. In one embodiment, Fig. 5a (not shown), the device comprises a silicon wafer 6 doped with boron and phosphorus as acceptor and donor impurities and with the addition of zinc to form the deep trap level. Electrodes comprising gold wires 7, 7<SP>1</SP> containing gallium are secured to opposite sides of the wafer by ultrasonic welding. Curve A (Fig. 6, not shown) illustrates the relationship between light intensity and critical field strength for such a device when operated at the temperature of liquid helium and may be compared with curve B due to conventional silicon cryosar. In a second embodiment (Fig. 5b, not shown) the device comprises a germanium wafer 8 doped with indium and antimony as donor and acceptor impurities together with zinc to form the deep trap level are provided with electrodes 9, 9<SP>1</SP> formed by alloying indium grains to its opposite sides Curve C (Fig. 6, not shown) illustrates the characteristic obtained with this form of the invention in comparison with curve D due to a conventional germanium cryosar. Instead of using zinc as the impurity for forming the deep trap level a heavy metal such as nickel, gold, iron or thallium may be employed. Alternatively, the deep trap level may be formed by introducing lattice defects, dislocations, interstitial atoms or atom vacancies by X-rays or other like radiation or mechanical deformation.

Abstract: 990,153. Infusers and like packages. G. J. D. WELIN-BERGER. March 16, 1964 [March 18, 1963], No. 10923/64. Heading B8C. A bag 3, with contents for brewing a beverage is enclosed in an outer protective envelope 4, the edge 18 of which remains connected to the bag by a string 5 after withdrawal of the bag (Fig. 3) and is used for holding the bag after immersion in the beverage. In the form shown, envelopes 4 are formed around bags 3 by intermittently advancing a web of paper 6 between guiding and folding devices 8 and packing plates 11, 12 (Fig. 1). Bags 3 are lowered therein and the plates are brought together to cut the web 6 by knives 16 and incisions 17 and to seal the open edges of the envelopes 4 so formed (Fig. 2). The strings 5, attached to the centre of the two compartmented bags 3, and, if required, a reinforcing strip 10, from a supply roll 9, are clamped in the upper sealed edge 18, the sealing being effected by heat sealing, in which case a plastics string will be more firmly secured to the envelope and may be welded to a plastics bag, or by cold contact adhesive. The plates 11, 12 may be replaced by rotary members in which case the web 6 is continuously advanced.

Abstract: 878,755. Extruding. FUCHS, H. J. March 30, 1960 [April 6, 1959], No. 11281/60. Addition to 858,159. Class 83 (4). In the extrusion of metals and alloys, the extruded product 11 is separated from the discard 10 at the end of extrusion by moving the discard rearwardly to stretch a portion of the product adjacent the discard and thereby reduce its cross-section, and then severing the product at the reduced section. After extrusion, the product is held by a clamp 9 of the kind described in the parent Specification, the ram 7 is partially withdrawn, Fig. 2 (not shown), and the container 5 with the discard 10 and dummy block 8 adhering thereto are then moved rearwardly thereby stretching the product. Finally, the stationary ram 7 pushes the discard and dummy block out of the container and the product is severed at the reduced section. In another embodiment, Fig. 6, the ram 71 has a transverse dovetail slot into which the end of the billet is pressed during extrusion. Thereafter, the product is held by clamp 9 whilst the ram is withdrawn to stretch the product. Finally, the clamp is released and the ram 7<SP>1</SP> further withdrawn to pull the discard out of the rear end of the container, Fig. 7 (not shown), where it is severed off at the reduced cross-section.

Abstract: 1,043,065. Hydraulically actuator fastenings. SCHWERMASCHINENBAU ERNST THALMANN, VEB. March 17, 1965, No. 11339/65. Heading E2A. [Also in Division B2] A linkage comprises a piston 6 and cylinder 5 respectively connected to an elbow lever 8, 9 and an eccentric shaft 4, Fig. 1 (not shown), of a jaw crusher (see Division B1-2), the cylinder being supplied with hydraulic fluid from a vessel 22 via a non-return valve 19 having an opening/ closing time ratio of 3:1, opened mechanically by the shaft 4 and closed by the pressure of the fluid, so that an operating stroke of the crusher may be effected on alternate revolutions of the shaft. In operation, when the valve 19 is open the cylinder 5 communicates with the vessel 22, and fluid in the cylinder is forced out into the vessel by the moving cylinder, and the piston retained in position by the crushing pressure. When the cylinder moves upwardly the excess pressure prevailing in the storage vessel forces the fluid back into the cylinder. Closure of the valve 19 prevents escape of fluid from the cylinder, so that the piston 6 is made fast with the cylinder. A safety valve 20 stops over pressure in the event of overload, and a manually actuable slide valve 21 prevents the valve 19 from operating, to permit the crusher to be started up when filled with material.

Abstract: 114,905. Kelly, T. D. April 25, 1917. Piston pumps; compound or multi-stage piston pumps; actuating pumps by fluid-pressure motors. -A triple expansion steam or vapour engine has a stationary cylinder 2 of two diameters in which reciprocates a cylinder 4 having a piston 5 reciprocating therein. The cylinder 4 and piston 5 are connected to opposite cranks. Fluid is supplied to the space 1 by a valve 3 and then passes through a passage 6 controlled by the cylinder 4 to a space 8 between the moving cylinder and piston and then through a passage 10 to the annular space 11, the exhaust from which is controlled by the valve 3. A modification adapted for use as a compressor is described wherein the fluid passes in the reverse direction. In the construction shown in Fig. 4 adaptable as an engine or compressor, the inlet and outlet or vice versa take place through passages 20, 21. The space 1 may form a cushioning-space or a pumping-chamber when the machine would act as a combined pump and engine. In a modification of this construction, the space 1 and chamber 8 may be connected on the movement of the cylinder 4 by a passage 6 as in Fig. 1. The machine then acts as a two-stage compressor or pump.

Abstract: 491,463. Wireless receiving - sets. GENERAL ELECTRIC CO., Ltd., and PETERS, W. H. April 22, 1937, No. 11542. [Class 40 (v)] In a wireless receiver the tuning control is hinged so that, on grasping the knob, movement about the hinge operates a switch for quietening the receiver when tuning from one station to another. The tuning control 1 is mounted on a, plate 2 which is mounted on a leaf spring 3, the other end of which is attached at the point 5 to a panel 4 of the receiver. The plate 2 carries a contact arm 7 provided at its free end with a contact 8 which co-operates with a fixed contact 9 mounted on the panel 4. In its free position the spring 3 maintains the plate 2 slightly inclined to the plane of the panel so that the contacts 8, 9 are open. In operation the knob 1 is first depressed to close the contacts 8, 9 and silence the receiver, and is then rotated until the tuning indicator shows that the desired station is tuned in. When the knob 1 is released the spring 3 moves the plate 2 to open the contacts 8, 9, and the new station is heard. A delay circuit may be provided so that accidental release of the tuning knob for a short period, during tuning, does not bring the receiver into action. Specification 491,446, [Group XXXVI], is referred to.
