Patent GB-2128292-A (GB)
Title: Improvements in or relating to switching mechanisms
Inventor: ROADS COLIN
IPC: F16K37/00
Filed: 1982-07-13
Abstract: Turbulent conditions in fluid storage tanks can cause level control mechanisms; e.g. Ball float valves, to oscillate between open and closed states. A fluid control switch permits or prevents passage of fluid from a pressure source; the switch being operably connected to a float assembly. A power mechanism eg a piston is so arranged that an effort is applied to the fluid control switch to drive it closed when the float has partially closed the switch. In use the power mechanism can be arranged to close the switch in response to sustained high or low levels. Such an arrangement extracts a control signal from the level of an interface between two immiscible fluids in a container, the mechanism's response being delayed such that the transient level variations associated with turbulence, are ignored; the device only responding to sustained level change. <IMAGE>

Title: Semiconductor devices
Inventor: MIGLIORATO PIERO
IPC: H01L27/144
Filed: 1982-07-27
Abstract: Shaped aluminium connectors 6 are formed directly onto a CdTe passivating layer 2 covering a substrate 1. In contrast to other conductors aluminium does not easily diffuse into the CdTe thereby altering its properties. Arrays of photodiodes may be formed by p-n junctions between a p-type substrate 1 and n- type areas 4 of the CdTe layer, within areas of insulating CdTe 2. The aluminium 6 connects each diode to a bonding pad 8. The areas of n-type CdTe may be formed by diffusion of indium cadmium or boron or by ion implantation of aluminium or boron, or by deposition of islands of doped CdTe by M.B.E. techniques. <IMAGE>

The vessel is adapted to receive a sampling probe 5 adjacent to the end of the inlet tube such that the total area of the apertures is at least equal to the cross-sectional area of the tube. The spacing of the apertures along the length of the tube is such that when a liquid flows through the tube the volume of liquid passing through the apertures at each segment level is in a fixed exponential relationship to the volume of liquid passing through the apertures at the subsequent segment levels in the direction of flow. <IMAGE>

Title: Semiconductor device of the type in which a node is precharged in one clock state and selectively discharged in another
Inventor: MIYATAKE HIDESHI
IPC: G11C11/409
Filed: 1984-02-14
Abstract: An MOS transistor semiconductor device of the type in which a node is precharged in one clock state and selectively discharged in another in which circuit delay times are rendered substantially independent of variations in the power supply voltage. First and second MOS transistors are provided to form a leakage path circuit 100, so that the precharge node is charged to a voltage appreciably lower than the supply voltage. The drain of the first MOS transistor 101 is connected to a precharge node NP, while its source is connected to the drain of the second MOS transistor 102. A precharge signal  phi P is applied to the gate of the first MOS transistor. The on resistance of the second MOS transistor is preferably about one-third that of the first MOS transistor. In this circuit arrangement, a decrease in the precharge level during the precharge period due, for instance, to a transient in the power supply level, is suppressed so that the ordinary circuit operation is carried out with a constant delay time.   <IMAGE>

Title: High purity copper wire for bonding a semiconductor device and process for producing the same
Inventor: MORIKAWA MASAKI
IPC: C22C9/00
Filed: 1986-03-26
Abstract: The present invention eliminates the problems associated with the use of oxygen-free copper and other high-purity copper materials as bonding wires. In accordance with one aspect of the present invention, at least one rare earth element, or at least one element selected from the group consisting of Mg, Ca, Ti, Zr, Hf, Li, Na, K, Rb and Cs, or the combination of at least one rare earth element and at least one elemented selected from the above-specified group is incorporated in high-purity copper as a refining component in an amount of 0.1-100 ppm on a weight basis, and the high-purity copper is subsequently refined by zone melting. The very fine wire drawn from the so refined high-purity copper has the advantage that it can be employed in high-speed ball bonding of a semiconductor chip with a minimum chance of damaging the bonding pad on the chip by the ball forming at the tip of the wire. In accordance with another aspect of the present invention, 0.5-3 ppm of a rare earth element and/or Y is further incorporated as an alloying component in the zone-refined high-purity copper.

Title: Flocculation monitor
Inventor: MEETEN DR G H
IPC: G01N15/00
Filed: 1986-11-05
Abstract: A flocculation monitor which makes use of shearing force applied to a dispersion of free or discrete colloidal particles to distinguish between particles in their flocculated and non-flocculated states. White light from a tungsten-halogen lamp 1 run from a stabilised power supply is focussed approximately by a lens 2 onto the influx bundle 4 of a bifurcated optical fibre bundle. The incident light can be wavelength-selected by a variable-wavelength interference filter 3 to give a maximum reflectance change according to the particular type of dispersion being measured. The back-scattering of the dispersion 13 is measured by the light entering the efflux bundle 5. This light is then detected by the silicon photodiode 10, and the optical signal is processed and displayed by the display unit 11. The dispersion 13 is held in a cell 6 with an optically-absorbing base 7. This cell is rotatable by stepping motor 9 via shaft 8, either continuously, or in steps in one direction, or in steps in alternate directions. These then give a continuous shear, or time-dependent shears, respectively. The mode of shear, the shear rate and the angle of shear are controlled by the motor control logic 12. A flow-through cell may alternatively be used, and the shear may be varied by a variable speed pump or a periodically actuated valve, instead of using rotation. <IMAGE>
