Patent GB-2237566-A (GB)
Title: Glass ceramic article
Inventor: HINZ PAUL
IPC: C03C17/34
Filed: 1990-10-15
Abstract: A glass ceramic article decorated with ceramic stoved colouring agent is described, in which a layer of SiO2 20 to 200 nm thick is arranged between the decoration and the glass ceramic material. The SiO2 layer can additionally contain, for the purpose of adapting the refractive power to the refractive power of the glass ceramic, up to 66.5% by weight of oxides altering the refractive power, in particular TiO2, ZrO2, SnO2, MgO or Al2O3. In the process for producing the decorated glass ceramic article, the SiO2 layer may be produced by a sol-gel process. Preferably, an SiO2 gel layer, where necessary precondensed by a brief heat treatment, is produced on the still glassy article; the decoration is applied to this gel layer, and thereafter the glassy article is subjected to ceramization, during which the SiO2 gel layer is converted to an SiO2 layer and the ceramic colouring of the decoration is stoved. The SiO2 layer in particular allows sharp-contoured, "halo"-free decorations to be produced.

Title: Pressure compensating apparatus and method for chemical treatment of subterranean well bores
Inventor: CORONADO MARTIN P
IPC: E21B34/00
Filed: 1990-04-30
Abstract: A pressure compensating member 300 acts as a check valve to prevent upward flow in well tubing above well treatment apparatus, but allows a pair of inflatable packer elements (not shown) to deflate. The compensating member 300 has a cylindrical outer housing 301 and a valve housing 314 concentrically movable relative to and within the cylindrical housing. A fluid flow passageway 302 is within the valve housing and extends to the top of the well. Valve head 303, 304 and seat means 305, 306 are carried by the housing for selective blocking of fluid flow in one direction through the passageway when the valve head and seat means are in a first relative position and permit fluid flow in that direction through the valve housing when the valve head and seat means are in a second relative position. A pressure chamber 316 is provided within the outer housing and extends to the lowermost side of the valve head means. Biasing means 315 are provided for biasing the valve housing 314 to contract the pressure chamber with the biasing means being energized by a decrease of pressure within the fluid supply conduit such that the valve housing is moved relative to the outer housing to expand the pressure chamber without movement of the valve head means relative to the valve seat means. The compensating valve member may also be used independent of the inflatable apparatus either alone or in combination with another auxiliary tool within the subterranean well. <IMAGE>

Title: Motor protection switches
Inventor: HUMPHREYS DAVID WALTER
IPC: H01H37/54
Filed: 1990-12-20
Abstract: A motor protection switch for use with automobile window lift motors for example is constructed to provide advantageous fast break, slow remake characteristics. The switch comprises a plastics body portion (1) into which are moulded first and second rigid metal parts (2, 3) which define, on one side of the body portion, the electrical supply terminals of the switch (2', 3') and on the other side a mounting (3'') for a fixed contact (6) and an elongate heater bridge (2'') from the distal end of which an elongate snap-acting bimetal (4) is cantilevered with the bimetal extending back towards the body portion and carrying at its end a moving switch contact (5) which co-operates with the fixed switch contact (6). The heater bridge (2'') is formed of a resistive material, eg nickel silver, such as to heat up during current-carrying operation of the switch and serves to pump heat into the bimetal (4) during switch operation so as to ensure a fast break and a slow remake. <IMAGE>

Title: Automatic ticket dispenser
Inventor: CHAMBERS BRIAN
IPC: G07F7/04
Filed: 1990-12-21
Abstract: An automatic ticket dispenser reads and stores the serial number of a banknote that is accepted as payment for a ticket as well as the serial number of the ticket. if the banknote is later discovered to be a forgery, the ticket bought with the banknote can be identified and confiscated when next used. Preferably an optical scanner 10 reads the number on the banknote, the output from the scanner being sent to a computer 12. The entire area of the banknote may be masked except for the area bearing the serial number. If the note is accepted by a note validator 4, a ticket is issued from a stack 6 and conveyed to dispensing slot 9. The ticket may be a railway ticket, a telephone card, or a fuel card. <IMAGE>
Patent GB-2243032-A (GB)
Title: Hybrid type device and manufacturing method thereof
Inventor: KOMINE YOSHIHARU
IPC: H01L21/60
Filed: 1991-02-19
Abstract: A hybrid-type device is constructed using bumps 4A, which electrically connect the electrodes of function elements 2 arranged on a first plane substrate 1 to those of function elements 7 arranged on a second plane substrate 6, the bumps being formed from conductive thermoplastic resin. Since the thermoplastic resin does not have a definite melting point, the bumps do not short-circuit when one substrate is heated and the two substrates are pressed towards one another while the bumps soften. Further, should a void form under a bump during the pressing, the air in the void is readily forced out through the softened bumps by pressure. For these reasons, a highly reliable device is available. <IMAGE>

Title: Thermoplastics branch pipe connector
Inventor: OWENS PAUL
IPC: B29C65/34
Filed: 1991-10-08
Abstract: A thermoplastics connector, for use in connecting a thermoplastics branch pipe to thermoplastics pipes of a main pipeline when the branch pipe and the main pipeline pipes have substantially the same diameter, comprises a tubular through coupler 1 provided with a socket 2 at each of two opposite ends thereof. Each socket has a coil 9 of electrical resistance heating wire and the coils 9 are electrically interconnected. The connector also includes a tubular spigot 3 extending from and in flow communication with an intermediate region 4 of the coupler between sockets 2. The outer diameter of spigot 3 is substantially the same as the inner diameter of sockets 2 to enable spigot 3 to be connected to the branch pipe by a conventional double socket electrofusion fitting. In order to prevent belling of the connector when under pressure in use, the wall thickness of the connector is locally increased outwardly in a part 4A of the connector at and adjacent the junction between the spigot 3 and the intermediate region 4 of the coupler. <IMAGE>

IPC: G03F1/00
Filed: 1993-11-08
Abstract: In a method for producing a field effect transistor, a positive photoresist (2) is deposited on a surface of a semiconductor substrate (1), the positive photoresist (2) is exposed to light through a mask having an asymmetric intensity profile, the positive photo resist (2) is converted into a negative photoresist e.g. by heating and uniform exposure the negative photoresist is developed to form a pattern (2b) having an aperture (3) opposite the gate electrode formation region of the substrate (1) and asymmetric overhanging portions (2b1, 2b2) in the aperture (3), the semiconductor substrate (1) is wet etched using the photoresist pattern (2b) as a mask to form a asymmetric recess (40) in the semiconductor (1), and a gate metal (5a) is deposited using the photoresist pattern (2b) as a mask to form an asymmetrically placed gate electrode (5) in the recess (40). Therefore, only one exposure process provides the photoresist pattern (2b) having asymmetric overhanging portions (2b1, 2b2) in the aperture (3) of the pattern (2b). Various masks with asymmetric profiles are disclosed (Figs. 2 and 4 - 7). <IMAGE>

IPC: H04B1/38
Filed: 1994-04-27
Abstract: A portable radio apparatus 100 includes a housing 1, a receiver unit 10, a transmitter unit 3, and a hinge member 2. The housing has a longitudinally elongated, thin, rectangular parallelepiped shape. The receiver unit 10 is arranged on one surface side of an upper portion of the housing to be located inside the housing.
