Title: Image forming device
Inventor: YAMAZAKI HIROYUKI
IPC: G03G15/04
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To decrease ozone, to miniaturize a device, to reduce cost and to form a stable and excellent image by forming a latent image on the surface of an image carrier while moving a photoreceptive film where a photoreceptive layer is formed on a conductive layer. SOLUTION: The photoreceptive film 16 is like a sheet where a transparent conductive layer is formed on the upper surface of a transparent base plate and further the photoreceptive layer consisting of a charge generating layer and a charge transporting layer is formed on the upper surface of the conductive layer. In a state where electric field is formed, take-up rollers 17 and 18 are driven to move the film 16 in a subscanning direction so as to perform reversal- exposure to the film 16 by a laser beam. The laser beam reaches the charge generating layer of the photoreceptive layer of the film 16.  When electric field between the surface of the photoreceptive layer and the surface of an image carrier belt 2 rises and exceeds a threshold, discharage is generated and the surface of the dielectric layer of the belt 2 corresponding to the exposure position of the film 16 is electrified to form the electrostatic latent image having a positive polarity by the freed positive carrier of generated carrier pair.

Title: Method for rolling seamless steel pipe by mandrel mill system
Inventor: HAYASHI YASUYUKI
IPC: B21B17/04
Filed: 1984-03-30
Abstract: PURPOSE:To form a pipe stock of seamless steel pipe into an uniform wall- thickness rolling material by reducing the radial dimension of the front end of a round-bar mandrel from its prescribed position and preventing the variation of wall thickness caused by the difference of temperature drop at the time of rolling each part of a hollow blank material in which the mandrel is inserted. CONSTITUTION:A round bar mandrel 3 is inserted into a hollow blank material 4 of seamless steel pipe, to roll the material 4 into a pipe stock by many rolls. The front end from the prescribed position of mandrel 3 is formed into a shape stepped or reduced gradually in diameter. The front end of the heated hollow blank material 4 in which the mandrel 3 is inserted, is rolled into a small diameter, because of the temperature drop and the rolling resistance with time are still small. But the wall thickness is not smaller than the prescribed dimension because the mandrel 3 is reduced in diameter, and the wall thickness of pipe stock is made uniform throughout is whole body.

Title: Apparatus and process for burning dry hydrocarbon with low nox
Inventor: SANJIEI MARUKU KOREA
IPC: F23C99/00
Filed: 1990-03-14
Abstract: PURPOSE: To reduce NOx as a combustion product, by comprising a first fuel combustion means for high-concentration combustion of hydrocarbon fuel at sufficiently large equivalent ratio(ER), a cooling means, and a second fuel combustion means for combustion of cooled combustion gas product at sufficiently small ER. CONSTITUTION: The inlet of a combustor 20 accepts x% of air from a compressor 12. 100% of a fuel is supplied to the combustor 20 for combustion of high-concentration fuel with less air. Since the combustor 20 is relatively dense, it operates at equivalent ratio(ER) of about 2.5-3. A combustion product is sent at relatively high temperature to a cooling stage 22. The temperature is lower than about 2780 deg. F at which hot NOx is produced. The cooling stage 22 cools a hot synthesized gas produced by the combustor 20 while cooling the synthesized gas as low as an ignition points or below before it is sent to a mixing device 14. The cooled synthesized gas and an air gas at compressor temperature are mixed in the mixing device 14, producing a lean preliminary mixed flow comprising ER of about 0.5 on inlet side of a combustor 16 while about 0.3 on outlet side.  Prompt NOx occurring in the combustor 16 is very less.

Abstract: PURPOSE:To obtain a high purity crystal thin film with good reproducibility by feeding reaction gases into a crystal growing chamber with care not to mix each other, and moving a substrate so as to contact the gases to epitaxially grow each atomic layer. CONSTITUTION:A plurality of reaction gases are introduced into a crystal growing chamber, and a crystal thin film is formed on a substrate 15 on a susceptor 13 placed in the chamber 7. Here, the gases are fed with care not to mix each other to a predetermined position in the chamber 7, and the substrate is brought into contact with the gases at the predetermined position to grow the thin film for a predetermined time. Group III and V stock gases are wholly separated to adhere each one layer on the substrate 15, and only the surface ration of the substrate 15 is utilized to eliminate a problem, such as an automatic doping as the growing temperature drops. Thus, a high purity crystal thin film is obtained with good reproducibility.
