  • Patent number: 5524381
    Abstract: A building including high efficiency transparent insulation and optical shutter solar collector (HETIOSSC) to effectively control heat loss and gain in a passively-solar climate control system. HETIOSSC includes a layer of protective glazing, a transparent insulation, an optical shutter, an optional solar radiation absorbing material and optional heat storage elements. When the building and its heat storage are too warm, the optical shutter layer becomes opaque to prevent overheating. During cloudy and cold winter days, HETIOSSC still has a solar transmission and insulation efficiency great enough to collect sufficient sunlight for heating. Location of HETIOSSC on the roof, rather than the walls, does not alter shape and orientation of a building.

  • Patent number: 5523710
    Abstract: A voltage level of an output node is reversed by an inverter. An output of the inverter is used as an initial setting signal. A feedback switching transistor is also provided in an initial value setting circuit. Furthermore, there is provided a limiting device for eliminating an abnormal operation of the feedback switching transistor until the inverter starts a normal operation, in the event of momentary power failure or when the electric power source is quickly turned on after a very short break. Accordingly, normal operation of the inverter is assured even in such an abnormal condition accompanying momentary interruption of power supply, thereby surely outputting an initial setting signal.

  • Patent number: 5523865
    Abstract: The present invention relates to a thinfilm transistor array designed to drive an active-matrix type liquid-crystal panel to be incorporated in a liquid-crystal display device, and is to offer a thinfilm transistor array solving the conventional problems of disconnections possible between the display electrodes and the drain electrodes and short-circuits possible between the display electrodes and the data wiring. By these, high-quality images can be displayed with a high reliability can be obtained together with an improved fabrication process thereof. In order to accomplish these objectives of the invention, the display electrodes of said thinfilm transistor array are disposed between the gate insulation layer and the inter-insulation layer, and the display electrodes are connected to the drain electrodes by means of a data wiring disposed through contact holes provided through the inter-insulation layer.

  • Patent number: 5522052
    Abstract: A pipeline processor comprises a memory stage arithmetic unit, a data dependence detecting unit and a control unit. The data dependence detecting unit outputs a detection signal to the control unit when it detects the data dependent relationship between a load instruction LD and a subtraction instruction SUB to be executed next thereto. The control unit receives the detection signal to control such that load data to be loaded from a memory unit according to the load instruction LD is inputted to the memory stage arithmetic unit. The memory stage arithmetic unit executes subtraction by using the load data in a memory stage of the subtraction instruction SUB.

  • Patent number: 5520658
    Abstract: A dispensing device for dispensing at least two fluids comprises a housing (12,22) of a pistol-like configuration having an integral handle (50), in which a spring-biased trigger (60) is received. Within the housing (12,22) of the dispensing device (10), two syringes (80,81) are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover (22) of the housing is closed, the motion of the trigger (60) relative to the handle (50) is transmitted to a toothed rack which cooperates with a propeller body (70) in a ratchet-like manner. The ratchet-like cooperation allows a uni-directional motion of the propeller body (70) and prevents a motion of the propeller body (70) in the opposite direction.
