Title: Magnetic pulse compression circuit
Inventor: OSHITA IKUTO
IPC: H03K5/04
Filed: 1989-07-31
Abstract: PURPOSE:To suppress jitter while saturating a saturable reactor forcibly and to attain synchronization operation with high accuracy by providing a secondary winding to a saturable reactor and connecting a pulse generator to the secondary circuit. CONSTITUTION:A capacitor 5 is charged through energizing a semiconductor switch 3 and an output trigger pulse voltage from a pulse generator 12 is fed to a secondary winding 82 of a saturable reactor 8 at a specified time at the time of ending a charging pulse to the capacitor 5 to saturate the reactor 8 forcibly. As a result, the reactor 8 reaches the saturation and the compressed pulse charging to the capacitor 6 is applied succeedingly. In such a case, a current supplied by the pulse generator 12 is an exciting current to the reactor 8 and a small current can do and as the output pulse voltage of the generator 12 is high, the time till the reactor 8 is saturated after the pulse voltage is applied is reduced to suppress jitter. Thus, the synchronization operation with very high accuracy in the amplification of a laser beam is attained.

Title: Production of marking sheet
Inventor: SAITO MASAO
IPC: C09J7/02
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To produce a marking sheet which is free from whitening during the storage of its roll by sticking a resin sheet formed on a process paper to a self-adhesive layer formed on a release paper, winding up the resultant laminate, unwinding it, and peeling off the process paper while simultaneously winding up the rest again. SOLUTION: In a production process of a marking sheet, a synthetic resin sheet formed by casting and drying a synthetic resin (e.g. polyvinyl chloride) sol on a process paper is stuck to a self-adhesive layer formed on a release paper and the resultant laminate is wound up. The roll of the laminate is then unwound and, while the process paper is being peeled off, a marking sheet comprising the resin sheet and the self-adhesive sheet is wound up together with the release paper again into a roll. Thus, the pressure applied to between the surface of the marking sheet and the back side of the release paper is reduced, preventing the whitening of a marking sheet occurring during the storage of its roll.

Title: Device to change blow direction
Inventor: IRITANI KUNIO
IPC: F24F13/32
Filed: 1987-08-10
Abstract: PURPOSE:To make the space to install a device small by forming the air passage as a smoothly curving curved passage and providing an air discharging port of one side at the downstream end of the curved passage and opening the other air discharging port on the outer side of the curve of said curved section and providing a damper at the curved section.
