Title: Laminated polyester film
Inventor: TANAKA SHOTARO
IPC: B32B27/36
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a laminated film having excellent flame retardant effect and good productivity by laminating heat resistant resin layers on both surfaces of a polyester film, and setting a drip rate when burned to a specific value or below. SOLUTION: As a polyester in a polyester film (hereinafter referred to as a 'film'), it is not particularly limited, and a polypropylene naphthalate or the like is used. As the film, a film biaxially oriented in the state that a laminated film is provided is desired. A drip rate of the film is 10% or below. Here, the rate is obtained by a combustion test based on UL94VO standards. The film having such a small drip rate is obtained by laminating heat resistant resin layers on both surfaces of the film. As the heat resistant resin, a resin soluble in a bipolar aprotic solvent is suitably used. In this case, an aromatic polyamide resin is suitable. As one example, an N-methyl-2-pyrrolidone can be used.

Title: Gas discharge lamp
Inventor: KIRA KENHIRO
IPC: H01J61/16
Filed: 1978-08-10
Abstract: PURPOSE: To make an increase of B-component and G-component of the light, by specifying each sealing amount, with the components, contributing toward the discharge lighting of gas discharge lamp, constituted by xenon, mercury and thallium.  
     CONSTITUTION: To a gas discharge lamp are sealed a xenon of 1 to 10 atm., mercury of 0.01 to 0.5mg/cc and thallium iodide of 0.01 to 0.5mg/cc. With a sealing made by such value of composition, a color rendering becomes worse than exenon short arc discharge lamp, however with a better performance as a three-color decomposition projector. This is because B-component and G-component become weak in the light resolving process, with a short amount compensated.

Title: Exposure quantity controller
Inventor: NAITO YOSHIICHI
IPC: G03G15/043
Filed: 1987-04-20
Abstract: PURPOSE:To eliminate the influence of variation in density in a circumferential direction by varying a lamp voltage set value for original density according to a visual image density measured value and the lamp voltage of an exposure lamp when the visual image density is measured. CONSTITUTION:An original density detecting means A detects the density of an original E to be reproduced. A visual image density detecting means B, on the other hand, detects the density of a visual image formed on a photosensitive drum F. Their detection results are supplied to a control means D. The control means D obtain information from the original density and visual image density supplied from both detecting means A and B and varies the set value of a proper lamp voltage for the original density according to the visual image density and the value of the lamp voltage when the visual image density is measured. Therefore, the quantity of exposure is therefore determined by correcting the proper lamp voltage based upon the original density according to condition variation which causes variation in the lamp voltage. Consequently, proper image reproducibility is secured.
