IPC: A01D69/00
Filed: 1989-12-16
Abstract: PURPOSE:To use an engine always in a good condition by determining a set value of speed reduction by number of revolutions of engine before rotation. CONSTITUTION:A speed controlling means 100 which operates when a working vehicle is in a rotating and traveling state and number of revolutions of an engine becomes smaller than a set value of speed reduction is equipped.

Title: Copper material having high conductivity and high oxidation resistance, and formation thereof
Inventor: SHIMOYAMA KOJI
IPC: H01B5/02
Filed: 1994-12-28
Abstract: PURPOSE: To reduce a cost, improve solder wettability, decrease the reduction of the soldering property, and prevent the deterioration of adhesive strength by setting the content of a prescribed element higher at a portion to the prescribed depth from a surface of a copper material than that at the inside. CONSTITUTION: At the time of the heat treatment of a copper material, aluminum, an aluminum compound, or a mixture of them are made to coexist, and an element having low standard formation free energy of an aluminum oxide is made to coexist with them. The content of the element at the portion to the depth of 0.1μm from the surface of the copper material is set higher than that at the inside. When the total content of the element is set to less than 5atm%, high conductivity is preserved, and high oxidation resistance can be easily obtained. Since oxidation reaction is suppressed, the deterioration of the soldering property caused by the oxidation of the Cu metal surface is improved, and the soldering property can be improved.

Title: Method for driving and controlling rotating body
Inventor: KAMOSHITA MIKIO
IPC: H02P29/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To make the circumferential speed of a rotating body constant, even if the rotating body is eccentric by detecting the amount of eccentricity in relation with its rotational position. SOLUTION: The amount of eccentricity in a rotating body 1 which is driven rotationally by a drive source 7 is detected corresponding to the rotational position of a photosensitive body 1 of the rotating body. Based on the detected amount of eccentricity and the corresponding rotational position, the target rotational position of the photosensitive body 1 of the rotating body is varied and adjusted, so that circumferential speed of the photosensitive body 1 of the rotating body remain constant. As a result, travel amount per unit time in the circumferential positions, that is, the circumferential speed, of the photosensitive body 1 of the rotating body, is made constant even if the rotating body is eccentric.
