Title: Ultraviolet ray protective film and shrink film
Inventor: CHIKU MASAMI
IPC: B65D65/20
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain both transparency and ultraviolet ray protection characteristics in an ultraviolet ray protective film and a shrink film by using PEN and realize both inexpensively without degrading strength. SOLUTION: The ultraviolet ray protective film 1 comprises a base material 2 made of polyethylene terephthalate and a fine powder 3 made of polyethylene naphthalate dispersed therein. The shrink film is manufactured by imparting shrinkability to the ultraviolet ray protective film 1 at the time of or after manufacturing the film 1. Thus the obtained film can exhibit higher ultraviolet ray protection characteristics than a film made of a single PET body due to ultraviolet ray absorbing effects of dispersed PEN particles. In addition, two regions different in refractive index are formed in the film, and reflection of ultraviolet rays incident from the outside occurs on their interface, so that it is possible to reduce light which passes through the film and reaches inside.

Abstract: PURPOSE:To transfer a black toner image to the position registered with a specified color toner image formed on a paper by conveying the paper with the sepcified color toner image transferred on it and synchronizing the revolution time of a photosensitive body for reproducing the specified color with the 2 revolution time of that for reproducing black. CONSTITUTION:A red-system electrostatic latent image formed on a photosensitive body 7 is developed with a red toner in a red-reproducing developer 17. This toner image is transferred to a paper 22 fed from a paper feeder 21, and conveyed through the first and second belt conveyors 23, 24 to a photosensitive body 5. The distance L between the transfer position of the body 7 and that of the body 5 is set in advance so as to be similar to or more than the peripheral length of the body 5. When the paper 22 with the red toner image transferred on it comes just to the transfer position of the body 5, the body 5 makes one revolution, and the black toner image formed on the body 5 is just registered with the red toner image on the paper 22.

Title: Manufacture of semiconductor device
Inventor: NOZAWA HIROSHI
IPC: H01L21/76
Filed: 1980-03-06
Abstract: PURPOSE:To improve the characteristics, by forming an oxidizing material layer such as poly Si and the like on a substrate, providing a channel stopping layer on the substrate by using an oxidation resistant mask, selectively oxydizing said material layer, and reducing the strain in the substrate in an element separating process. CONSTITUTION:In the process of forming an element separating region, a thermal oxide film 2 is formed on the Si substrate 1. Thereafter a poly Si layer 3 is provided on the entire surface. A nitride film pattern 4 is provided on the element forming region. An impurity layer 5 having the same conducting type as that of the substrate 1 is ion-implanted with the nitride film 4 as a mask. Then thermal oxidation is performed, and exposed poly Si 3 is transformed into a thick oxide film 6. Thereafter, the nitride film 4, the underlying poly Si 3, and the oxide film 2 are etched out. Then the element forming process is performed. Since the thick oxide film 6 can be formed in a relatively short time and a separate oxide film is not provided in the substrate 1, large strain is not yielded in the substrate 1 and the deterioration in characteristics can be avoided. Since lateral expansion of the oxide film 6 can be made small, this method is suitable for high integration.

The heat resisting temperature of polybenzooxazole containing fluorine is as high as at least 400 deg.C and its durability is also excellent. Therefore, the polybenzooxazole does not melt even in fixing process. In addition, the film is not static charged due to friction because is contains fluorine so that a toner image is not disturbed. Subsequently, it is possible to obtain a highly heat- resistant, highly durable reversible thermosensitive medium. Furthermore, polybenzooxazole containing fluorine is no static charged easily and its transparency is high. Therefore, printed image quality is superb.

Abstract: PURPOSE:To reduce electromagnetic vibration and electromagnetic noise by providing an anchored press plate axially or radially movable on the inside diameter side of a keep plate and by increasing rigidity with an addendum section strongly fastened so that the press plate can be moved with an adjusting screw. CONSTITUTION:Plural circular recessed sections 7a and screw holes 7b lying in a row are provided along the circumferential direction at constant intervals on the inside diameter side of the surface that comes into contact with an outside space piece 3 of a keep plate 7.
