Filed: 1982-12-10
Abstract: PURPOSE:To rationalize an assembling process, by performing insert molding in an injection molding process by using a reel pressing leaf spring having a resin film sheet adhered to the single side thereof. CONSTITUTION:A bow shaped reel pressing leaf spring 12 having a resin film sheet 1 adhered thereto prior to starting injection molding is inserted and, thereafter, pressure reduction is performed from a pressure reducing hole 9b while a reel pressing leaf spring 12 is fixed to a recessed part 9b.

Abstract: PURPOSE:To obtain a rewriting type optical data recording medium enhanced in recording preserving reliability by excessively adding Sb to a recording film represented by (GeTe)2{(Sb/Bi)2Te1}. CONSTITUTION:When Sb, (GeTe)2(Sb2Te3)1 and (GeTe)2(Bi2Te3) are shown by mol.%, the proper component ratio of a recording film is within a range surrounded by an A1-point (70, 30, 0), a B1-point (5, 95, 0), a C1-point (5, 0, 95) and a D1-point (70, 0, 30). Within this range, the amount of Sb in the recording film is excessively increased and crystallization temp. rises and the environmen tal temp. durability of a recording state can be improved. When the principal constitution of an optical medium is obtained by successively laminating a dielectric film, the recording film, the dielectric film and a metal film on a substrate, high speed recording and high speed erasing capacity are effectively enhanced and it is desirable that ZnS is used in the dielectric film and at least one material selected from Al, Cu, Au and Ag is used in the metal film. As a result, an optical medium excellent in the preserving reliability of recording is obtained without deteriorating high speed erasing capacity.

Abstract: PURPOSE: To efficiently produce Fe-Cr-Al-REM based alloy powder by adding REM to Al-contg. Fe based molten metal after its S is decreased, then allowing the molten metal to flow from a molten metal nozzle and subjecting the molten metal to atomization with a high-pressure gas, etc. CONSTITUTION: The Fe based molten metal contg. Al, for example, the molten metal consisting of 15 to 40wt.% Cr, 3 to 10% Al, <=10% O, <=0.03% N, 0.0005 to 0.1% REM and the balance substantially Fe is allowed to flow down out of the molten metal nozzle.

Title: Synchronous detection system
Inventor: HOSHINO YUJI
IPC: H03L7/10
Filed: 1984-10-19
Abstract: PURPOSE:To prevent a step-out by measuring the time from one change point to the next change point of a received clock for sampling received data, and monitoring the phase difference between the received clock and received data all the time and correcting the phase difference. CONSTITUTION:The received data from a demodulator 1 is inputted to a decoding circuit 2 and a sign change point detecting circuit 10. The sign change point detecting circuit 10 when detecting a change in sign samples the received data an extremely short time later, and sends a signal to a phase comparing circuit 13 when deciding that the change in sign is not caused by a noise temporarily. The phase comparing circuit 13 incorporates a counter and counts the time between signals from the detecting circuit 10 with the clock from a clock generating circuit 15 to calculate the phase difference between the received data and received clock. When the phase difference is smaller than a specific value, PLL processing is carried out at it is and when larger, the counter of the clock of the clock generating circuit 15 is initialized. Consequently, the step-out of a reception side is prevented.

Title: Transfer device for can shell
Inventor: TERAOKA TOSHICHIKA
IPC: B65G15/58
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a transfer device for a can shell, which can stably transfer a can shell at the high speed without being inverted or jammed during its transfer. SOLUTION: A can shell 2 is transferred over a pin chain conveyor 3 and a first vacuum conveyor 4 at a transfer speed v1 while its interval is being kept at L1, and it is transshipped to a second vacuum conveyor 5 set up so as to be continuous to the downstream side of the first vacuum conveyor 4. Since the second vacuum conveyor 5 is driven at a transfer speed v2 relatively lower than the transfer speed v1 the can shell 2 is thereby forwarded to an air flow conveyor 6 at the low speed. For this reason, even if metallic powder and the like are adhered to the bottom part 2b of the can shell 2 so as to allow the bottom part to be hardly slipped, the can shell can be prevented from falling sideway and jamming when it is transferred, so that the can shell 2 can thereby stably be transferred.
