Title: Roller
Inventor: UEDA KENJI
IPC: B65H3/06
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a roller which is generally used and excellent in assembleability and capable of reducing costs. SOLUTION: A roller is constructed by fitting a roller shaft 2 to the roller fitting hole 13 of a roller main body 1. An elastic locking piece 14 is unitedly formed in the tip part of the roller shaft 2, and a locking claw 15 is formed in the locking piece 14. When the locking claw 15 is pushed into the roller shaft fitting hole 13, the locking piece 14 is elastically deformed. The locking claw 15 is pulled out from the roller shaft fitting hole 13 in the fixed positions of the roller shaft 2 and the roller main body 1, and thus the locking piece 14 is returned to its original position and the locking claw 15 is locked in the side face of the roller main body 1.

Title: Roll device
Inventor: INOUE HITOSHI
IPC: H05B6/14
Filed: 1987-07-21
Abstract: PURPOSE:To make the temperature distribution of a roll shaft uniform in the axial direction by arranging a yoke installed between magnetic flux generating mechanisms in a tilted attitude relative to the axial direction. CONSTITUTION:A yoke 11 is inserted in a tilted attitude between a magnetic flux generating mechanism 8 constituted with a plurarity of iron cores 9 and solenoid coils 10 mounted on and arranged in the axial direction of a fixed shaft 1 and the magnetic flux generating mechanism 8 of a roll device constituted with a hollow roll 5 freely rotatably supported with the fixed shaft 1 via a bearing mechanism 6. With this constitution, the roll 5 facing the yoke 11 is displaced in the axial direction. As a result, magnetic flux is always flowing in the axial direction of the circumference of the roll 5 near the border between the magnetic flux generating mechanisms 8, which induces an electromotive force. The electromotive force causes a current to flow in the roll 5 to generate heat and, as a result, temperature distribution in the axial direction is made uniform.

Title: Vapor growth method for organic metal
Inventor: IKEDA MASAKIYO
IPC: H01L21/205
Filed: 1992-06-17
Abstract: PURPOSE:To improve uniformity without impairing characteristics by growing thin films in a temperature range of a material transporting rate-determining speed in which growth does not depend upon the growth temperature or the temperature range of a reaction rate-determining speed in which the growth rate is increased with the growth temperature. CONSTITUTION:A position of an RF coil of a barrel type reaction furnace is regulated to improve a temperature distribution in a gas flowing direction. GaAs is grown at a substrate temperature of 580 deg.C (reaction rate-determining speed range). Thus, an irregularity in a thickness of the films can be remarkably improved. After GaAs of high purity is grown 2-3mum as a buffer layer on a GaAs substrate, the GaAs carrier concentration of X10<17>cm<-3> is grown 0.5mum as an active layer. It is difficult to grown the GaAs layer of high purity at the reaction rate-determining speed, and merely grown only in a material transporting rate-determining speed range). However, since the buffer layer is for the purpose of recovering wrongness of crystallinity of a boundary between the substrate and the epitaxial layer, several % of an irregularity of the thickness of the films does not become a problem.
