Inventor: KONDOH HITOSHI
IPC: H01L23/522
Filed: 1985-11-08
Abstract: A semiconductor integrated circuit device has cell arrays (11-1, 11-2, 11-3) each constituted by unit cells (11A,11B, 11C, 11D, 11E) containing functional circuits (16, 19, 20, 23, 26). Polysilicon wiring layers (15A, 15B, 15C) or diffusion wiring layers are formed in the wiring regions (12-1, 12-2) provided among the arrays. A first metal wiring layer (13A, 13B, 13C) is formed by computer-aided design above each polysilicon wiring layer (15A,15B, 15C) or each diffusion wiring layer. An insulating layer is then formed on the first metal wiring layer (13A, 13B, 13C). A second metal wiring layer (14A, 14B) is formed by computer aided design above the insulating layer. A via contact hole (17) is cut in the insulating layer. A portion of the second metal wiring layer (14A, 14B) fills up the via contact hole (17), whereby the second metal wiring layer (14A, 14B) is connected to the first metal wiring layer (13A, 138, 13C). The via contact hole (17) is formed above each polysilicon wiring layer (15A, 15B, 15C) or each diffusion wiring layer. It may have its axis intersecting with the axis of the polysilicon or diffusion wiring layer or not intersecting therewith. In the first case, the overlapping portions of the first and second metal wiring layer (13A, 13B, 13C, 14A, 14B) are made broader to facilitate the forming of the via contact hole (17). In the second case, the portion of each polysilicon or diffusion wiring layer which is positioned below the via contact hole (17) is made broader than the other portions.

IPC: F03H1/00
Filed: 1985-02-08
Abstract: A method of obtaining mechanical energy utilizing multi- step H 2 0-plasma. A reactive thrust is produced by using plasma. The mechanical energy is produced by means of explosion of eletrically conductive plasma which is generated by dissociating H 2 0. In a first step H 2 0 (gas) produced by a carburretor is reduced to a plasmatic state by atmospheric discharge. In a second step the plasmatic gas is treated by further stronger atmospheric discharge and high-frequency induction heating, and the level of its energy is raised to a point such that a plasma jet is ready to be produced. In the third step plasma jet is generated by periodically modulating the high voltage for the second atmospheric discharge, and a high-pressure thermal explosion reaction is caused by synchronizing the generation with compression of the plasma jet resulting in that energy produced by the plasmatic reaction in the plasma jet at ultra-high temperature is converted to mechanical energy.

Abstract: A semiconductor device characterised in that it comprises:
     (A) a layer of semiconductor material comprising an intermetallic semiconductor; and   (B) a first barrier layer adjacent one side of the said semiconductor layer, which barrier layer comprises phosphorus is disclosed.   
     Referring to the accompanying diagram, a semiconductor device 20 may comprise an intermetallic semiconductor layer 22 and barrier layers 23 and 24, the interface 26 causes a quantum well to develop. 
     A method of making a quantum well device characterised in that it comprises depositing a barrier layer comprising phosphorus on an intermetallic semiconductor comprising a pnictide is also disclosed. 
     Phosphorus and polyphosphides MP x , wherein M represents an alkali metal and x varies from 16 to infinity, have bandgaps larger than those of many of the currently used binary, ternary and quaternary semiconductors and have good interface properties therewith. Layers of phosphorus and such polyphosphides may be used as barriers in quantum well devices, particularly those using other semiconductor layers comprising a pnictide. The barrier layers may be, for example, MP x  wherein x varies from 15 to infinity, M represents an alkali metal and P represents phosphorus. Phosphorus is the preferred barrier layer and may be monoclinic phosphorus, red phosphorus or amorphous phosphorus having a layer-like, puckered sheet-like local order. Quantum well and hetero-junction devices are further disclosed. These have applications in field effect devices,such as MESFETS, ring oscillators, two-dimension electron gas transistors, photodetectors and lasers. 
     The present invention provides advantages over the prior art.

Abstract: A composition which provides an elastomeric, electrically conductive product upon removal of the water at ambient conditions is described. The composition comprises an emulsion (A) having a dispersed phase of elastomer and a continuous phase of water containing a material selected from the group comprising colloidal silica, alkali metal silicates, and organosilicates, and (B) electrically conductive, metal coated spheres having a diameter of from 5 to 105 micrometres. Because the dispersed particles of elastomer are crosslinked before the metal coated spheres are added, when the water is removed from the emulsion, the metal coated spheres and the dispersed crosslinked elastomer are found in a continuous polar phase. The cured elastomer, having a surface resistivity of less than 2 ohms per square on at least one surface is particularly useful in producing an efficient shield for electromagnetic radiation in the radio and television frequencies.

Abstract: A broad-band switching network module is presented with the aid of which the synchronisation problems occurring in the building-up of relatively large switching networks can be handled in a flexible manner. The switching network module according to the invention exhibits disconnectable synchronisation facilities (1 and 2) at the input and at the output of the signal paths. In addition, the clock supplied at the clock input TE is supplied back to a clock output TA via isolating amplifiers (3 and 4). This makes it possible to build up a switching network in such a manner that it is not necessary at any point to connect two inputs in parallel and to a preceding output. This is an advantage particularly when a fast clock has to be distributed with the correct phase.

Abstract: A drive for the generation of a linear movement for a high-voltage, SF6 gas-insulated circuit breaker has a drive piston-cylinder arrangement (12) with a cylinder body (13) in whose hole (14) a drive piston (15) having a drive piston rod (16) can be moved to and fro by means of high-pressure fluid. The circuit breaker is connected to the end of the drive piston rod projecting from the cylinder body. The storage space for the drive is formed by the cylinder space of a piston-cylinder arrangement (27, 36) which can be compressed by a storage spring (42), a reservoir space (47) at low pressure additionally being provided for the high-pressure fluid. To simplify the design and to improve assembly, and especially to reduce the installed size, the reservoir space (47) is connected to the end of the cylinder body (13) on the drive piston rod side, and thus forms a unit, the drive piston rod reaching through the reservoir space (47). Furthermore, connected to the cylinder hole there is a cylindrical brake body (27) projecting into the reservoir space, which body is surrounded by a cup-shaped cylinder (36), the cylinder (86) and the brake body forming the storage space (61) for the high-pressure fluid. The storage spring which presses the cylinder over the brake body is provided outside the cylinder, in the reservoir space. <IMAGE>

Abstract: A first protective layer of SiO₂ (2) is formed on a polycarbonate substrate (l), an In-Sb alloy recording layer (3) containing 50 to 80 atomic% of Sb is formed on the first protective layer (2), a second protective layer of SiO₂ (4) is formed on the recording layer (3), and a surface layer (5) of an ultraviolet-curing resin is formed on the second protective layer (4) to prepare an optical disk. In order to initialize the optical disk, the recording layer (3) is entirely applied to a laser beam and is transformed into a stable phase crystalline state. In order to record information in the optical disk, the recording layer is locally exposed to a laser beam (8), and the beam-applied site (6) is melted. The site is then rapidly cooled to transform the phase into the metastable phase crystalline state, i.e., π-phase. In order to erase information from the disk, the recording mark (6) is exposed to a laser beam and heated to a temperature higher than a temperature of phase transformation between the stable and metastable phase crystalline states but lower than the melting point of the alloy.

Abstract: A three-phase stepping motor is automatically tested for excessive friction and winding shorts in less than four seconds. The stepping motor accelerates its rotor at a constant rate to a first predetermined velocity. the level of the current applied to the rotor windings to effect commutation is very low so that the rotor will stop and fail to complete any further steps in the test cycle if there is excessive binding or friction. After the rotor is rotated one revolution, it is accelerated at a constant rate to a second and higher predetermined velocity with the current applied to the rotor windings being increased to a second and higher level at a selected velocity during acceleration. When the rotor reaches the second predetermined velocity, commutation is stopped immediately but current is still applied to at least one phase of the motor. An acceptable motor will continue to turn and generate an AC back electromotive force (EMF) signal in the energized phase of the windings. A motor, which has excessive friction or a winding short, will not produce an AC back EMF signal because it will not be moving. With an acceptable motor, the elapsed time between stopping the application of current to the rotor windings to stop acceleration and when the rotor coasts to a stop is displayed and enables comparison of the degrees of friction between acceptable motors.

Abstract: This invention relates to a lamination press (12) and the manufacture of laminates (62) in the press. The press includes a pressure vessel (12) divided into first (14) and second (16) chambers by a flexible material (18). An assembly of elements to be laminated is placed in the second chamber (16) and a vacuum is drawn in both chambers. A higher vacuum is drawn in the first chamber (14) than in the second (16) so as to prevent the entrapment of air in the laminar assembly (62) by external pressures. The first chamber (14) is then flooded with a heated, pressurized fluid, which exerts a compressive force on the laminar assembly (62) through the flexible material. Transfer of heat from the fluid to the laminar assembly is monitored by circulating the fluid through the first chamber (14) and comparing the enter­ing (24) and exiting (26) fluid temperatures. Heat transfer is controlled by varying the temperature of the circulating fluid and by changing its rate of flow through the first chamber (14).
