Title: Method for rolling steel plate
Inventor: YAMADA KENJI
IPC: B21B1/02
Filed: 1994-04-12
Abstract: PURPOSE:To prevent generation of seam flaws near the edge of a steel plate and to obtain a steel plate free from surface flaws in manufacturing a steel plate from a slab by hot rolling. CONSTITUTION:In manufacturing a steel plate by reducing the thickness of a stab 1 through hot rolling of plural passes, in all or part of the plural rolling passes, descaling is performed on all of the end faces on both sides in the width direction, or only on the proximity to the front and back faces of the side end face in the thickness direction, of the slab 1 before rolling in each rolling pass. Consequently, not only the primary scales existing on the surface of the slab stock, but also the secondary scales generated in a rolling process are removed, preventing the generation of seam flaws.

Filed: 1988-04-20
Abstract: PURPOSE:To always prevent slip properly by obtaining an aimed torque by subtracting the integration type correction torque and proportional correction torque from the max. torque which is obtained from the car body acceleration speed when the drive wheel slip is detected and by controlling the engine output. CONSTITUTION:In a traction controller 15 into which the output signals of the speed sensors 11-14 for driving wheels and driven wheels are inputted, the slip quantity DV corresponding to the difference between the driving wheel speed VF and the driven wheel speed VB is calculated.

When DV reduces, the correction torque TP which is obtained by multiplying a coefficient Kp by DV and the correction torque TS which is obtained by the integration- calculation of DV are obtained, and a standard torque TG is obtained from the acceleration speed of the driven wheel speed VB. Then, the aimed torque TPHI is obtained from the equation TPHI=TG-TP-TS, and the engine output is controlled.

Abstract: PURPOSE:To wash a device without generating characteristic deterioration or a fault by forming a void formation agent including layer through which water can not be allowed to pass at the innermost part of a sheathing resin at the surrounding of a void covering an entire piezoelectric element. CONSTITUTION:A ceramic oscillator 1 is formed of a piezoelectric element 2, outside terminals 3 and 4, two-layered sheathing resin 5, void 6 formed at the surrounding of the entire piezoelectric element 2, and void formation agent including layer being one part of the inside resin layer of the sheathing resin 5. Then, the layer 7 is formed by allowing a void formation agent to stick to the entire element 2 and the terminals 3 and 4, and allowing a porous resin layer constituting the innermost part of the multilayered sheathing resin 5 to absorb the void formation agent. Therefore, even at the time of washing the oscillator 1, it is possible to prevent water from penetrating through the pores of the resin 5, and sticking to the element 2. Thus, it is possible to wash the ceramic oscillator without generating the characteristic deterioration or the fault or the like.

Title: Pressure regulating valve

IPC: F02M51/02
Filed: 1982-06-08
Abstract: PURPOSE:To regulate pressure with high accuracy by urging a valve body to the outflow valve hole side with a seal holding spring to improve the opening and closing operation of the outflow valve hole. CONSTITUTION:When fuel pressure in a fuel feed path 4 is raised, fuel pressure in a pressure chamber 17 is also raised to push up a diaphragm 16. Thus, the seal surface 35 of a valve body 31 is separated from the valve seat surface 24 of an outflow valve hole 23. Hence, since fuel escapes through the outflow valve holes 23 and an escape pipe 21 to a return path 8, fuel pressure in a pressure chamber 17 and a fuel feed path 4 are held at a set pressure. Since the movement of a holding member 27 urged to the pressure chamber 17 side is regulated by a stopper mechanism 38, when the outflow valve hole 23 is closed by the seal surface 35 of the valve body 31, the valve body 31 closes the outflow valve hole 23 with a pressing force of a seal holding spring 37.
