Patent SE-320129-B (SE)
Inventor: LESK I
IPC: H01L29/73
Filed: 1965-05-14
Abstract: 1,053,442. Semi-conductor devices. MOTOROLA Inc. May 10, 1965 [May 18, 1964], No. 19651/65. Heading H1K. A field effect transistor is produced in a wafer comprising an N-type silicon layer 34<SP>1</SP> epitaxially deposited on a P-type silicon substrate 40, Fig. 4B (not shown), by oxidizing both major faces and selectively etching the oxide layer on the N-type surface to leave a circular region of oxide, Fig. 4D (not shown). Boron is diffused into the wafer to form P-type region 58 which reaches substrate 40 to completely isolate N-type region 34. During this diffusion a layer of borosilicate glass forms over the surface of the wafer. An annular aperture is etched in the masking layer and a second boron diffusion performed to form P-type top gate region 31 which defines the channel 33, the circular drain 30 and the annular source 32. Phosphorous is diffused into the drain and source regions to form N+ type enhancement regions 35, 36. The thin layer of phosphosilicate glass that forms is removed by etching, an annular region of masking layer 48 is removed over gate region 31, and the oxide layer is removed from the lower face of the wafer Fig. 4J (not shown). A layer of aluminium is evaporated on to the top surface and etched to form drain, top gate, and source contacts 25, 26, 27, and a layer of gold 44 is deposited on the lower face of the wafer. A plurality of devices may be produced simultaneously in the same wafer which is then cut into individual dice which are encapsulated by soldering layer 44 to a metal header 14, Fig. 1 (not shown), and thermocompression bonding fine wires to the contacts 26, 27, 25 and to the ends of lead-out wires 16, 17, 18. Wire 16, which is connected by fine wire 21 to the top gate contact 26 is also connected by fine wire 23 to header 14 which makes contact with region 40 part of which operates as the lower gate. The encapsulation is completed by welding cap 11 to header 14. The device is tested and classified according to its parameters. The device may be produced as part of a monolithic integrated circuit. Complementary devices may also be produced, but in these N+ type enhancement regions are unnecessary since the impurity concentration of the gate is sufficiently high for it to be unaffected by the aluminium contact.

Abstract: 1,130,116. Induction motors. SIEMENS A.G. 5 July, 1967 [19 July, 1966], No. 31059/67. Heading H2A. In a shaded-pole induction motor changing from 2 poles to 4 poles by the reversal of one of the pole-windings 7, the unwound poles have slots carrying additional windings 6 to suppress the third harmonic when operating on two poles. These slots are at 15 degrees to the unwound axis. Additional coils 9 at 45 degrees improve the performance in 4-pole operation. The main pole-faces are stepped to improve 4-pole operation. All the coils are concentrically wound about the main poles to facilitate winding.

Inventor: DIESEL HANS-DIETER
IPC: D06N7/06
Filed: 1984-04-19
Abstract: A process for the production of colored films of paper impregnated with synthetic resin which contain melamine resin and have a three-dimensional surface structure, by printing the paper films with a colored pattern using an aqueous protein-based printing ink and lacquering thereover. The color which is printed in the regions in which the lacquer layer is to be thinner than in the other regions contains a lacquer repellent, and the printed and dried paper film is impregnated with an aqueous impregnation of a melamine resin from the unprinted side, with the formation of a one-sided excess of resin, and is dried. The printed and impregnated film is coated on the printed side with an aqueous lacquer based on melamine resins, and the lacquered film is hardened at elevated temperature without applying pressure. A laminate is produced by joining the unprinted side of the hardened film to a substrate such as chipboard.

Title: Tape cassette having rewind control mechanism
Inventor: ARMSTRONG RICHARD J
IPC: G11B23/087
Filed: 1989-05-19
Abstract: A tape cassette which has a limited access rewind system includes a one-way coupling (40) arranged to communicate between the spool and the rewind mechanism. The one-way coupling mechanism includes an engagement disc (38) which is mounted in the housing and forms a part of the take-up spool (10). The one-way coupling device serves to engage automatically to prevent rotation of the spool relative to the engagement member in the unwinding direction and to release automatically to permit free rotation of the spool in the winding direction. A locking mechanism (80) is located in the housing which is operable to secure the engagement member against rotation and thereby prevent rotation of the spool in the take-up direction. The locking mechanism may be released to disengage the engaging member to permit free rotation of the engagement member and spool about the take-up access. The tape cassette also includes a releasable latching mechanism which serves to lock each spool against rotation during shipping and handling.

Title: Vinyl acetate catalyst preparation method
Inventor: NICOLAU IOAN
IPC: B01J37/03
Filed: 1993-10-14
Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by immersing the impregnated support in a reactive solution and tumbling the impregnated support in the reactive solution for at least 1/2 hour to begin precipitation of the insoluble compounds and completing precipitation of the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2 during the vinyl acetate forming reaction.
