IPC: H01L27/112
Filed: 1980-07-14
Abstract: A semiconductor device (30, Figure 3) comprising electrically alterable read-only memories (20, Figure 2) formed in and on the same silicon substrate (31) is disclosed. A bipolar voltage generator is formed on the same silicon substrate (31) in a block (32-11) electrically isolated from the block (32-1) containing the read-only memories, so that voltages of either polarity may be obtained selectively to control the gates of the read-only memories using only a unipolar external voltage source V(via lines L1, L2, Figure 3). The gate control voltage, supplied along line L3 (Figure 3), may be a high voltage for erasing memory, a lower voltage of the same polarity for reading memory, or a high voltage of the opposite polarity for writing memory.

Abstract: An arrangement for measuring the thickness of a strip emerging from a rolling mill is provided with a thickness measuring device and at least one linear inductor. The linear inductor exerts a pulling force on the strip which flatens the strip in the vicinity of the measuring device. This permits a measuring beam from the measuring device to pass through the strip in a direction orthogonal to the surface of the strip. In some embodiments, a plurality of linear inductors may be provided on either side of the strip, and on either side of the measuring device. The frequency of operation of the linear inductors may be controlled by a converter, in response to the speed of the emerging strip.

Abstract: By reason of the scanning regimen followed by a scanning gamma camera head, and the shape of the active region of the head, not all of the elemental areas of a scanned radiation field are observed by the active region of the head for the same period of time. This non-uniformity sensitivity of the system is corrected by correction factors (S.C.F.) that are either analytically calculated or experimentally determined for each given elemental area of the map that represents the radiation field (10). The map of an unknown radiation field (10) obtained by following the scanning regimen (18) is corrected by applying the sensitivity correction factors to the contents of corresponding elemental areas of the map.

Abstract: A tool holder for a manipulator comprises a tool shaft extending along and rotatable about a main axis and having a tool-shaft end provided with a pivot defining a transverse axis. A tool is carried on the pivot and is displaceable relative to the tool shaft about the transverse axis. A stack of guide rings coaxially surrounds the tool shaft adjacent the pivot and is formed with at least two throughgoing guide-ring passages each having a radially outwardly opening passage end. Two of the guide rings define a pair of axially spaced annular confronting guide-ring surfaces. A connector ring is rotatable on the stack between the guide-ring surfaces and has a pair of axially oppositely directed connector-ring surfaces one of which axially directly confronts one of the guide-ring surfaces. A connector element secures the connector ring to the tool-shaft end for joint rotation of same about the main axis. A flat contact element is secured to one of the one surfaces and is axially flatly engageable with the other of the one surfaces. Thus current can be transmitted between the connector ring and the guide ring of the one guide-ring surface by the contact element. A piston-and-cylinder assembly and a spring are engaged between the connector ring and the other of the guide-ring surfaces for pressing the one surface and contact element together axially. An electrical feed line is connected to the conductor fixed to the support and an electrical line is connected between the other conductor and the tool for feeding electricity through to the tool.

Air is introduced into the tank (by spargers 64) to maximize efficient ion transfer at the membranes. The tank (25) is provided above the rinse water tanks (10-13) and the inlet (27) and outlet (28) are arranged to prevent draining of the purifying tank into the rinse water tanks should a malfunction occur.

Abstract: Apparatus for sending pressure pulses through drilling fluid in a drill string in a well bore includes an assembly adapted to be lowered from the surface through the drill string to a position adjacent the lower end of the drill string. The external dimension of the assembly is substantially less than that of the internal diameter of the drill string, so there is always a substantial clearance between the assembly exterior and the drill string interior to permit a substantial flow of drilling fluid down the drill string, past the assembly, through a drill bit, and into an annular space between the drill string exterior and the well bore. The assembly includes an internal bore to permit drilling fluid to flow through the assembly. Means are provided for intermittently restricting flow of drilling fluid through the assembly bore to send the pressure pulses to the surface in response to the magnitude of a downhole condition to be measured. The assembly includes means to permit it to be retrieved by a wire line from the surface and without removing the drill string from the well bore.

Abstract: 57 A hinge assembly 3 for a sunroof panel 4 is located with its effective transverse pivot axis W only slightly rearward of the vertical plane containing the front edge 4a of the panel 4, so as to minimise compressive wear on the elastomer panel seal 10 when the panel 4 is opened. For example, a metal channel 15 secured to the flap has a rounded forward edge 35 fitting in a groove 12, and held thereby by elasticity of seal 10, optionally plus channel elasticity. A protective cowl 13 can protect this arrangement, and is capable of being pulled back around pivot Y by a finger pull in space S against over-centre mounting X-Y-Z. Such control movement also affects the securing of channel 15 to the pane 4, whereby channel 15 falls downwards to free the pivot 351l2 and thus allow the hinge assembly to be removed.

Abstract: Cutting horizontal, cantilevering objects of splittable material, such as de-barked tree trunks and the like is carried out with the aid of a guided, endless circulating saw chain (10), the upper cutting part of which is moved from below and upwards through the object. The lower edge portions of the cut surfaces at the cut are allowed to bear against each other under the action of the bending moment of the cantilevering object, while the return portion of the saw chain in the cutting area is kept free from the cut surfaces. The saw chain is guided by a chain guide (12) extending curvilinearly under the object and guides the return part of the chain. The chain guide and the guided return part are both outside and below the object during the whole of the cutting operation, while the upper cutting portion of the chain runs straight between the end points of the curved portion of the chain guide.Towards the end of the cutting operation, the part of the object not yet sawn through is subjected solely to short- duration tensional stress and substantially not for bending stress, whereby splitting the material is avoided.
