Title: Improvements in or relating to audio frequency thermionic amplifiers
IPC: H03F3/32
Filed: 1938-01-12
Abstract: 504,960. Valve amplifying circuits. FERRANTI, Ltd., SEARBY, N. H., and THOMAS, G. 1. Jan. 12, 1938, No. 965. [Class 40 (v)] An audio-frequency push-pull amplifier comprises two valves 9, 11, the valve 9 being fed from the preceding stage 18 and the valve 11 by the potential developed across the resistance 10, which is included in the output circuit of valve 9 and is connected in series between the two similar sections 7, 8 of the primary of the output transformer 6. Since the grid circuit of valve 11 does not contain an inductive element, the stability is increased. The transformer sections 7, 8 are wound so that the fluxes due to direct currents are in opposition and resistance 10 is such that the potentials across it are equal in magnitude whilst opposite in phase to the input potentials of valve 9. In order to balance out any hum in the output caused by ripple in the high tension supply P, half ot the hum potential of the supply is applied to the control grid of valve 9 and consequently an equal hum potential is applied in opposite phase to the control grid of valve 11. Since the whole of the hum potential is directly applied to the control grid of valve 11, the net hum potential on the grid of valve 11 is equal to and in phase with that on the grid of valve 9 ; hence none appears in the output. The required hum input to valve 9 may be developed across one arm of a potential divider formed by a preceding valve and its associated circuit elements, Fig. 4 (not shown). In the figure the hum input is obtained by adjusting the hum input to the preceding valve 18 by the capacity potential divider 19, 20. Alternatively the capacity potential divider may be replaced by a resistance potential divider, Fig. 6 (not shown). In Fig. 7 (not shown) the control grid of valve 11 is connected to a tapping on its grid leak so that the hum applied directly from the source is twice that applied from the output of valve 9.

Title: Improvements in and relating to aircraft wings incorporating a power installation for propulsion
Inventor: HEATH BERNARD OLIVER
IPC: B64C23/00
Filed: 1956-01-11
Abstract: 844,748. Jet propelled aircraft. ENGLISH ELECTRIC CO. Ltd. Jan. 4, 1957 [Jan. 11, 1956], No. 967/56. Class 4. [Also in Group XXVI] The wing structure of an aircraft comprises an upper and a lower panel and a system of ribs enclosing between themselves and the panels ducts open fore and aft and containing in their centre lines burners which, in combination with the ducts, form jet propulsion engines for the aircraft. Fig. 1 shows a perspective view, fully broken away and Fig. 2, a diagrammatic section of a wing. The lower wing panel 34 is provided with a panel 35 which, together with the upper wing panel 33, forms an isentropic air intake leading to combustion chambers 37; at the trailing edge the lower wing panel is provided with a flexible sheet 62 movable by jacks 63 to form a jet nozzle having an adjustable throat area. The upper and lower wing panels are connected together by a Wanen girder which divides the space between them into triangular ducts, in each of which is situated a ram jet burner 50. Behind the girder the panels are connected together by struts 60 having streamlined fairings 61. The wing panels and the Wanen girder may be of honeycomb sandwich construction and may be insulated from the hot air by lagging and by metal air screens 54. The space between the panels 34, 35 may accommodate spars and serve as a fuel tank, the tapering front and rear ends being blanked off by false spars 41, 42. The tank is divided horizontally by a baffle plate 43, and fuel flows outwardly from the wing root to the tip in the upper half and back to the root in the bottom half, thus cooling the wing surface and preheating the fuel. In an alternative arrangement, Fig. 3 (not shown), the upper wing panel extends beyond the lower one and carries the equivalent of panel 35, forming the isentropic air intake and containing the fuel tank.

Title: Dephosphorizing method of molten metal
Inventor: MATSUO TORU
IPC: C21C1/02
Filed: 1985-01-08
Abstract: PURPOSE:To produce Cr and Mn contg, ferrous metal having a low phosphorus content by adding a specific ratio of a rare earth element to the ferrous metal contg. easily oxidizing elements such as Cr and Mn, stirring the metal to dephosphorize the same and subjecting the metal to oxidation refining after removing the dephosphorization slag. CONSTITUTION:The rare earth element such as mischmetal is added at 0.1wt% ratio to the melt of a crude stainless steel, high Mn crude steel, etc. contg. the easily oxidizing metals such as Cr and Mn and the molten metal is stirred in a non-oxidizing atmosphere to cause the reaction so that the P in the molten metal is floated in the form of the phosphide of the rare earth element in the slag. After the dephosphorization slag is separated from the molten metal, the molten metal is subjected to the oxidation refining to decarburize and refine the crude steel as well as to oxidize the remaining excessive rare earth element to slag. Such slag is removed and the stainless steel and high Mn steel of the low phosphorus content are produced while the oxidation loss of the Cr and Mn is suppressed.

Title: Laser marker device
Inventor: KUWABARA KOJI
IPC: B41J2/465
Filed: 1988-01-06
Abstract: PURPOSE:To prevent liquid crystal molecules from being heated when it is irradiated with laser beams and avoid the reduction in marking contrast, by additionally providing a heat shielding function in an orientation film which is a component of said liquid crystal element. CONSTITUTION:At the time of marking, linearly-polarized laser beams 2 are projected to a liquid crystal element 1, which are turned to be penetrating laser beams 3 in accordance with the pattern data of a liquid crystal 4. The liquid crystal element 1 is composed of the liquid crystal 4, orientation films 5a, 5b, transparent electrodes 6a, 6b and, glass substrates 7a, 7b which hold all these components. The orientation films 5a, 5b are generally formed of organic polyimide, the thermal characteristic of which is not greatly different from that of the liquid crystal 4. For example, when the thickness of the orientation film 5a, 5b is 1mum, the maximum temperature of the liquid crystal 4 is 50 deg.C, whereas, when the thickness of the orientation film 5a, 5b is 0.09mum, the maximum temperature of the liquid crystal 4 is 62 deg.C which exceeds the operating limit of a liquid crystal 60 deg.C. As a result, although the printing efficiency is not changed at all in the former case, the contrast is deteriorated in the latter case. In other words, if the thickness of the orientation films 5a, 5b is made larger, the films can serve as a heat shielding layer.

IPC: H01L29/78
Filed: 1990-01-08
Abstract: PURPOSE:To obtain vertical power MOSFETs of high gate breakdown strength by such a design that a gate electrode extends only over a flat gate oxide film. CONSTITUTION:This invention is a MOSFET comprising a semiconductor substrate 1, a gate oxide film 8 deposited over the main surface of the semiconductor substrate 1, and a gate electrode 9 provided on the gate oxide film 8, where the gate electrode 9 should extend only over the flat gate oxide film 8. For example, the main surface of the substrate 1 except on a field oxide film 7 does not become flat, but the surface of a well that serves as a source well 2 and a source junction layer 3 becomes stepped 14 during the step to form a well. Except the step 14 a gate electrode 9 made up of a polysilicon film is provided on the flat gate oxide film 8. This design causes the gate electrode 9 extending over the flat gate oxide film 8 to make no field concentration; therefore, gate breakdown hardly occurs.
Patent JP-S59127144-A (JP)
Title: Bus circuit
Inventor: SUKAI TSUNEHISA
IPC: G06F13/00
Filed: 1983-01-08
Abstract: PURPOSE:To attain parallel and multiplex operations of many devices by connecting the addresses of processor memories for read-out of these addresses in the order of storage and reading and writing them cyclically. CONSTITUTION:The results of operations of each block and circuit are processed by a work memory WM which is shared. A reading address 502R of a common memory (not shown in the diagram) which is needed for transfer of information among blocks serves as an address pointer for the memory position where a partial address area is read out; while a writing address 502W serves as an address pointer at the memory position where the writing is carried out to the partial address area. The addresses within a partial address area 500 are connected logically to each other so that they can be read out cyclically in the order of storage. As a result, the reading and writing are carried out in the order of the cyclic connection order every time a partial address PA is given to the common memory.

Abstract: PURPOSE:To prevent a strain from being caused in an irradiation pattern due to heat of a mask while X rays are irradiated and to execute a precise and ultrafine working operation by a method wherein a diamond thin film is supported by a support frame and an X-ray absorber pattern is applied to this thin film. CONSTITUTION:A diamond thin film 2 is formed on the surface of a single- crystal silicon base material 1a to be used as a support frame 1. X-ray irradiation patterns 3 composed of Au are formed on the diamond thin film 2. Then, a protective film 4 is formed on the whole surface of the diamond thin film 2 including the patterns 3. The silicon base material 1a is etched from its rear up to the diamond thin film 2; the support frame 1 is formed; a mask is completed. A coefficient of thermal expansion of this diamond thin film 2 is very small; a thermal strain to be caused when a temperature of the thin film is raised by 1 deg.C during the use of the mask is about 0.01mum for the mask of 20mm square, which does not constitute an obstacle. In addition, because a thermal conductivity value of the diamond thin film 2 is large, the heat of the thin film can be dissipated quickly through the support frame 1.

Patent TR-27335-A (TR)
IPC: B22F3/26
Filed: 1989-11-09
Abstract: A metal matrix composite is formed by contacting a molten matrix alloy (18) with a permeable mass of filler material or preform (16) in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix alloy (18) will spontaneously infiltrate the permeable mass of filler material of preform (16) under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step,the matrix metal which has infiltrated the permeable mass of filler material or preform (16) is directionally solidified. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.
