Publication number: 20090229131Abstract: A control handle included in a bush cutter is provided. A driving controller is switched on so that the cutting blade is driven in an adjusted speed mode at a rotation speed set by a speed adjuster. The control handle includes a high-speed mode controller configured to set the rotation speed of the cutting blade to a high rotation speed, and an interlock device provided between the driving controller and the high-speed mode controller and configured to interlock the driving controller and the high-speed mode controller when the high-speed mode controller is switched on so as to move the driving controller concurrently with the high-speed mode controller. When the high-speed mode controller is switched on, the driving controller is concurrently switched on by the interlock device so that the cutting blade is driven in a high-speed mode.Type: ApplicationFiled: March 10, 2009Publication date: September 17, 2009Applicant: Fuji Jukogyo Kabushiki KaishaInventors: Hideki Tomiyama, Masanobu Yoshimura

Publication number: 20080120793Abstract: A method of leather processing which, without need of using a large amount of a hardener, etc., can yield a leather which can retain a three-dimensional shape, especially one with a fine, highly attractive design, for a long time and has high stretchability and high recovery while retaining the flexibility inherent in leathers; and a leather of a three-dimensional shape, especially a processed leather of a pattern and shape such as ones formed by wringing the leather together. The method comprises deforming a flat leather into a three-dimensional shape having recesses and protrusions and heating at least part of either or both of the protrusions (2) and recesses (1) to cure the heated parts and thereby cause the leather to retain the three-dimensional shape. More specifically, the protrusions and the recesses are partly heated while keeping the remaining parts being insulated from the heat to cure the heated parts only.Type: ApplicationFiled: February 1, 2006Publication date: May 29, 2008Inventor: Hideki Tomiyama

Patent number: 6825573Abstract: A flywheel, a cooling fan and a recoil starter are mounted on a crank shaft of an engine, thereby forming an engine unit. A power generating body is mounted on the end of the engine unit with the aid of an adapter intervening therebetween. The adapter and a rotor shaft are interconnected by means of a through bolt. A control system of the engine generator may be changed to an AVR type or an inverter type control system by removing the through bolt and replacing the power generating body with another. Accordingly, it is possible to provide an engine generator which allows the control system to be replaced with another type control system by easy replacing work.Type: GrantFiled: April 12, 2002Date of Patent: November 30, 2004Assignee: Fuji Jukogyo Kabushiki KaishaInventors: Misao Suzuki, Hideki Tomiyama
