Title: Synchronizing signal generation circuit
Inventor: EZAKI TORU
IPC: H04J3/06
Filed: 1994-12-15
Abstract: PURPOSE: To provide a synchronizing signal generation circuit which can reduce the influence of transmission bit errors of synchronizing signals and can generate the stable synchronizing signals. CONSTITUTION: A frame pulse counter part 10 estimates a frame where the synchronizing signal transmission bit is set at 1 based on the frame pulse that is compensated by a frame pulse compensation part 9. A synchronizing signal transmission bit extraction part 11 extracts a synchronizing signal transmission bit out of the estimated frame. If this extracted bit is equal to 0, a decision part 12 decides a bit error and generates a synchronizing signal or the part 10 stops its estimation of a frame. Then a synchronizing signal transmission bit detection part 13 detects a synchronizing signal transmission bit of '1' and decides whether the estimation of a new frame should be started or not.

Abstract: PURPOSE:To obtain a press die by which can obtain a high-quality saddle-like product free from a crack, etc., at one stage and expect reduction of man hour for operation and manufacturing cost. CONSTITUTION:In the state where a work (w) is held between an upper pad 13 falling with the fall of an upper die 11 and a lower pad 3, the tip of a bead forming member 7 enters the recessed part 16a of a bead forming upper member 16 to form the bead wa on the work (w) and the work (w) is bent into a U- shape by cooperation of the lower punch 2 and the upper die 12 by the continued fall, an opposite camber part is formed to be drawn in the final shape as the bead wa is elongated by the fall of the further continued upper die 11. Since the opposite camber part is formed as the bead wa is elongated, an excessive tensile stress does not occur and defects such as a crack, etc., do not occur.

Title: Sheet and film winder
Inventor: IIJIMA HIROSHI
IPC: D04B15/88
Filed: 1993-12-13
Abstract: PURPOSE:To save a space and to prevent the generation of the wrinkles of the surface of a film by a method wherein a winding core holding part and a drive part therefor are vertically movably held by a support post, and a reel weight detecting mechanism for a winding core is provided. CONSTITUTION:A winding core 1, winding core holding parts 3 and 4, a drive motor 5, a control part 6 therefor, and a second drive body 7 are integrally formed and vertically movably mounted through the slide grooves 13, 14, and 15 of support posts 10 and 11. When, with the progress of winding, the weight of a reel is increased, a moving part is lowered in a state that a counterweight is lifted by the mechanisms of the support posts 10 and 11. When a moving part is lowered to a lower position, winding is continued by a surface drive roller and drive mechanisms 5 and 6. When winding is completed, a paper sheet is cut by a cutting mechanism and after a reel is discharged, a new winding reel is mounted on a holding mechanism and winding is successively executed in an upper position. This constitution eliminates the use of a turret winder having high capacity and needing a wide space and saves a space.

Title: Balance for measuring plate-like sample
Inventor: KAWAHARA NORIO
IPC: G01G21/22
Filed: 1991-11-27
Abstract: PURPOSE:To always accurately measure the very small mass variation of a wafer, etc., without receiving any influence from air currents, etc., by providing shielding plates above and below supporting matters in such a state where the shielding plates are not brought into contact with a frame body and the supporting matters. CONSTITUTION:Wafers for reference and measurements W0 and W1 are respectively placed on supporting matters 3 and 6 by means of a wafer handling tool. When, for example, a supporting matter 5 is lowered and, at the same time, the supporting matter 6 is raised, the wafer W1 at a lower position gets on the supporting matter 6 and is separated from a frame body 1. Under such a condition, a motor 9g is stopped and weight measuring data D0 of a balance are read. Then, when the supporting matter 5 is raised by rotating the motor 9g in the opposite direction, the wafer W0 at an upper position gets on the supporting matter 3 and is separated from the frame body 1. Under such a condition, the motor 9g is stopped and the weight measuring data D1 of the balance are read. At the time of reading the data D1, the data D1 are not affected by air currents, since shielding plates 11-14 respectively shield the upper and lower surfaces of the wafers W0 and W1 from the air currents. A CPU calculates the data D0-D1 and stores the calculated value delta0 in a memory.
