Title: Phosphorescent resin composition
Inventor: KUROISHI OSAMU
IPC: C08K3/28
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a phosphorescent resin composition having an extremely long afterglow time. SOLUTION: 100 pts.wt. resin capable of forming a highly transparent film is compounded with 10-150 pts.wt. crystalline phosphor containing an activator and 10-100 pts.wt. transparent filler to obtain the objective composition.

Title: Optical magnetic memory
Inventor: TAKI KAZUYA
IPC: G11B11/10
Filed: 1981-11-13
Abstract: PURPOSE:To simplify the whole constitution of an optical system and to perform stable signal reproduction by using an optical circulator which has at least three ports, and separating incident light to an information recording carrier from reflected light from the information recording carrier. CONSTITUTION:Laser light from a semiconductor laser SL3 is polarized by an acoustooptical polarizer 11 in three directions, and those components illuminate the 1st port PA of an optical circulator 12, emitted from the 2nd port PB, and focused on a magnetic disk surface 4 through an objective L12 to form three spots. Then while the reflected light from the magnetic disk surface 4 is emitted from the 2nd port PB of the optical circulator 12 through the 3rd port PC, the current plane of polarization is preserved, so a rotary component of the plane of polarization by magnetic Kerr effect is also transmitted with fidelity, and the reflected light from the magnetic disk surface 4 never returns to the semiconductor laser SL3 through the 1st port PA, thus preventing the operation from being unstable.

Title: Method for supplying oxidation preventing gas to semiconductor manufacturing device
Inventor: ARIE MAKOTO
IPC: H01L21/50
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To reduce the running cost of a semiconductor manufacturing device by controlling the feed rate of an oxidation preventing gas supplied to the device when abnormality occurs by reducing the feed rate of the gas or stopping the supply of the gas after the heating operation of a heater is stopped. SOLUTION: The oxidation of a lead frame 1 is prevented by supplying an oxidation preventing gas into a carrying device 10 which carries the frame 1 in a state where the frame 1 is heated with a heater 12. When abnormality occurs, the feed rate of the gas is reduced or the supply of the gas is stopped after the heating operation of the heater 12 is stopped. When, for example, abnormality occurs, the carrying device 10 is automatically stopped by a stop signal outputted from a controller 21. The controller 21 stops the heating operating of the heater 12 by outputting an 'OFF' signal to a heater switch 16 a prescribed period of time after the controller 21 outputs the stop signal.  The controller 21 also stops the supply of the gas from a gas nozzle 14 by outputting an 'OFF' signal to a solenoid value 18 a prescribed period of time after the controller 21 stops the heating operation of the heater 12.
