Title: Antiskid braking method
Inventor: SANO YOSHIAKI
IPC: B60T8/66
Filed: 1989-07-20
Abstract: PURPOSE:To prevent unnecessary control of adjustment of a brake pressure and to provide a high brake force by a method wherein when, right after the starting of braking, a brake pressure amount to be reduced is set to a value higher than a given value, control is made so that control of the regulated pressure of a brake pressure is started. CONSTITUTION:During running of a vehicle, a slip amount of a wheel is computed by a control device 50 from a deviation between a wheel speed and a car body speed along with brake operation. The computed slip amount is corrected according to a car body speed, and based on a slip amount after correction, solenoid valves 30, 32, and 34 are opened to open an oil passage to a reserve tank 6. Meanwhile, solenoid valves 40, 42, and 44 are closed to cut off an accumulator pressure amount. In this case, when right after the starting of braking, a brake pressure amount to be reduced is set to a value higher than a given value, control of the regulated pressure of a brake pressure is started, and prohibition of a slip amount is not rendered ineffective before control of the regulated pressure is started. This constitution prevents control of regulation of an unnecessary brake pressure.

Inventor: KANEGA SHIRO
IPC: B65H65/00
Filed: 1992-06-24
Abstract: PURPOSE:To easily correct the dislocation of the stop position of a filament body by installing a M shaped guide on the tip end of the press roller of a movable arm pressing the filament body which is moved so as to be stopped at a specified position by a transverser pulley after the specified winding quantity of the filament body has been taken up. CONSTITUTION:When a filament body 4 such as a cable core and the like is taken up, the filament body 4 is taken up onto a bobbin 3 while a transverser section 5 is being moved at a specified pitch up to a set value of filament length. In this case, the winding end of the filament body is dominated by both a set pitch and the set value of filament length, therefore, the winding end is not necessarily come up to a definite position. This is a reason why a terminal end pressing means 6 pressing the terminal end of the filament body 4, is provided to correct the dislocation of the stop position of the filament body 4. The terminal end pressing means 6 including both a movable arm 14 and a pressing roller 15 with a M shaped filament guide 16 provided at the tip end of the roller, guides the filament body 4 through the M shaped filament guide 16 so as to position it at its specified position by moving the pressing roller 15 to a place close to the bobbin 3 side from its evacuation position with an air cylinder 17 operated.

Abstract: PURPOSE:To improve heat exchanging performance by a method wherein the resistance of fluid upon passing through a heat exchanging plate near an inlet pipe is made smaller than the same at the outer side of a heat exchanger to improve the branching of the flow of the fluid. CONSTITUTION:A multitude of heat exchanging plates 12, in which the width of the partitioning plate 11 at the center of the same is made wider than the other partitioning plates 11, and seal plates 13 are laminated alternately while end plates 14 are laminated to contact them with the heat exchanging plates 12 so as not to leak fluid from grooves 15, then, the inlet tube 16 of fluid is attached to the end plate 14. The fluid, entered from the inlet tube 16, is branched to the grooves 15 and flows out of the heat exchanger. Different fluids flow through each sheets by laminating the heat exchanging plates 12 while turning them by 90 deg. respectively. Accordingly, the grooves 15 become heat exchanging units to effect heat exchange between both upper and lower different fluids. The width of the partitioning plates 11 of the heat exchanging plates 12 near the inlet tube 16, whereat the flow amount of the fluid is much, is widened and, therefore, resistance of the fluid at the outer sides of the heat exchanger is smaller and the fluid can be branched uniformly into the grooves 15 after colliding against the partitioning plates 11 and being diffused whereby the improvement of heat exchanging performance can be contrived.
