  • Patent number: 4328263
    Abstract: In a method of manufacturing semiconductor devices, liquid glass is applied to the substrate of a semiconductor device to cover the upper surface of a film of photoresist formed on a conductor layer of the substrate and used as an etching mask for patterning the conductor layer. The substrate is baked at a sufficiently high temperature to harden the liquid glass and deform and shrink the photoresist film to expose the sides of such film. The photoresist film is removed. The hardened liquid glass on the photoresist film is simultaneously removed by lift off.

  • Patent number: 4328262
    Abstract: A layer of aluminum on a semiconductor substrate is covered by a layer of phospho-silicate glass. The surface of the semiconductor chip is covered with a positive photoresist film which is then heat treated. An upper surface of the photoresist film is covered with a polyimide resin which is heat treated, thereafter. If the semiconductor device is devoid of the layer of phospho-silicate glass, and the layer of aluminum is exposed, a positive photoresist film is interposed on the aluminum and the polyimide resin is applied to cover the upper surface of the interlayer, and is heat treated.

  • Patent number: 4310947
    Abstract: A support device pivotally supports a resilient body on the leading surface of either a door or sliding door frame in a manner whereby the gravitational force on the body moves the body between a sliding door and the frame. The body is mounted on a rod which is loosely accommodated in a mounting housing to prevent the transfer of the shock of impact of the door on the body to the housing. The body is manually movable away from the door and the frame, so that the body is positioned by gravitational force in abutment with the leading surface of the door when the door is closed. This permits the door to be securely closed with its leading edge in abutment with the frame. The body is interposed by gravitational force between the leading edge of the door and the frame when the door is open thereby preventing the door from closing fully by preventing the leading edge of the door from abutting the frame and thus protecting hands from being crushed between the door and the frame.

  • Patent number: 4311546
    Abstract: A method of surface treatment of a layer grown on a semiconductor substrate by chemical vapor deposition technique for removing a projection appearing on the layer comprises the steps of forming a layer on the semiconductor substrate by chemical vapor deposition technique, forming a membrane of plastic material that resists etching on the layer, pressing a flat plate against the plastic membrane on a projection of the layer to expose the projection, and etching the projection.

  • Patent number: 4306613
    Abstract: A cold bank tank in an enclosure for storing thermal energy in a very small area contains a liquid heat transfer fluid and has a top which is the top of the enclosure and a spaced opposite bottom. An inside heat exchanger extends from the bottom of the tank in the enclosure for cooling warm air in the enclosure rising by natural convection, returning the cooled air to the enclosure and transferring the warm air to the tank wherein it warms the fluid in the tank. An outside heat exchanger outside the enclosure is spaced from the top of the enclosure and coupled to the tank. A plurality of energy storage rods in the fluid in the tank store thermal energy in a very small area. The heat warming the fluid is transferred to the energy storage rods and when the outside temperature decreases below a predetermined magnitude, heat is released from the rods to the liquid fluid and vaporizes the fluid.

  • Patent number: 4303036
    Abstract: A container has an air tank therein occupying some of the space in the container. A projecting part extends from the container and has an open end coupled to the air tank via an air duct. A hole-filling member is mounted at the open end of the projecting part. A pump in the container selectively pumps sea water into the container and out of the container for maneuvering the container beneath the hull of a damaged sea vessel to position the hole-filling member of the projecting part in a hole in the bottom of the hull. Compressed air is supplied to the air tank to control the buoyance of the container and for expanding the hole-filling member in the hole in the hull to plug the hole.

  • Patent number: 4301442
    Abstract: A vehicular anti-theft device has a clamping member for clamping the tire of a vehicle under pressure to prevent rotation of the wheel of the vehicle on which the tire is mounted. An actuating device mounted on the vehicle and coupled to the clamping member selectively moves the clamping member onto the tire to clamp the tire and away from the tire to release the tire. A control mounted in the vehicle and coupled to the actuating device includes the ignition switch of the ignition system of the vehicle. The control controls the operation of the actuating device to clamp the tire when the ignition is turned OFF and releases the tire when the operator of the vehicle provides a predetermined code indication.

  • Patent number: 4293941
    Abstract: A memory access control system in a vector processing system comprises a memory unit, a memory device, address holding registers, a shift register and data buffer registers. The memory access control system distinguishes each vector data read out from the memory unit based upon the address holding registers by the output of the shift register. The shift register stores vector element numbers indicated by the memory device and transfers same to the data buffer registers. Each number from 0 to n-1, of a vector A composed of n elements a.sub.0, a.sub.1, a.sub.2, . . . a.sub.n-1, is a vector element number and each data, from a.sub.0 to a.sub.n-1, is vector element data.
