Patent JP-S59137975-A (JP)
Title: Fixing device
Inventor: AOKI TOMOHIRO
IPC: G03G15/00
Filed: 1983-01-28
Abstract: PURPOSE:To obtain a stable copy picture having no wrinkle by arranging a rotatable guide roller which increases or decreases in diameter gradually and axially from the center part to both end parts at the sheet entry side of a couple of fixing rollers. CONSTITUTION:The guide roller 5 is so tapered that the diameter decreases gradually from the center part to both ends in the axial direction. A sheet P received by the roller 5 moves along the surface of the roller by its own weight and is sent into the gap between the fixing roller 1 and roller 5. The front end of the sheet P abuts on the surface of the roller 1 to move downward, but the roller 5 is tapered, so both end parts of the front end abut on the surface of the roller 1 before the center part and reaches the contact point (a) between the roller 1 and a pressure roller 2. Therefore, the front end part P' of the sheet P which moves in the same direction with a belt 12 has both end parts clamped by the couple of rollers 1 and 2 earlier than the center part and they are drawn to eliminate unevenness of the sheet; and fixation is performed by a heater 4 and the couple of rollers 1 and 2.

Title: Manufacture of surface treated steel sheet for container having superior corrosion resistance and seam weldability
Inventor: SAITOU TAKAO
IPC: C23C22/00
Filed: 1984-01-26
Abstract: PURPOSE:To obtain a surface treated steel sheet for a container having superior seam weldability and corrosion resistance by coating the surfaces of a steel sheet with Ni, Co or Cu, bringing the metal into a diffusion reaction with the base metal, and carrying out tinning and chromating. CONSTITUTION:Coatings of one or more amont Ni, Co and Cu are formed on the surfaces of a steel sheet by <=50mg/m<2> per one side. The coatings may further contain one or more among P, Cr, Zn and Fe. The coated steel sheet is heated in a reducing atmosphere to diffuse part or all of the metal of the coatings in Fe as the base metal. The steel sheet is then subjected to temper rolling, and it is tinned as usual and chromated without carrying out reflowing. By this method, deterioration in the corrosion resistance and seam weldability can be prevented. In case of conventional thin tinning, such deterioration is caused. Since a reflowing stage is eliminated, a surface treated steel sheet for a container is obtd. at a low cost.

Abstract: PROBLEM TO BE SOLVED: To enable the braking force of rear wheels to control always optimally in an non-skid control device which controls the braking force of the rear wheels according to the slip state of front wheels. SOLUTION: The control mode is corrected so that the pressure reduction gradient of rear wheels located backward of a vehicle advance direction at the time of hydraulic pressure reduction becomes large by detecting the road surface under front wheels has changed from high μ (μ = friction coefficient) to low μ according to a slip rate of the front wheels located forward of the vehicle advance direction, in a device controlling the brake oil pressure by setting a control mode showing a direction and gradient of decrease and increase of the brake oil pressure for each wheel of the vehicle. Moreover, when the oil pressure of the rear wheels is increased, the control mode is corrected so that the increased pressure gradient of the oil pressure becomes large by detecting the road surface under the front wheels has changed from low μto high μ according to the increased pressure gradient of the oil pressure of the front wheels. Consequently, the increase and decrease direction of the oil pressure of the rear wheels can be set up based on the slip state of wheels, and also the gradient when the oil pressure is increased or decreased can be controlled optimally corresponding to the state of the road surface.
