Title: Hydraulic shock-absorber
Inventor: SUGANUMA TATSUMI
IPC: F16F9/32
Filed: 1986-02-26
Abstract: PURPOSE:To aim at the reduction of frictional heat and the stabilization of damping force in a hydraulic shock-absorber by axially extending its recessed grooves up to the medium point in the axial direction of a sliding surface, and then facilitating the hydraulic oil in a cylinder to be fed onto the sliding surface. CONSTITUTION:Frictional heat generated is quickly removed by the oil introduced into concave grooves 21, 22 provided on the sliding surface of a piston 17 and recessed grooves 26, 27 provided on a bushing 25 so as to suppress the thermal expansion therein. While, these recessed grooves 21, 22, 26, 27 axially extend from one end and the other end of the sliding surface to the medium point in the direction of the sliding surface, and accordingly, it becomes easier for the hydraulic oil in a cylinder 12 to be fed through these recessed grooves onto the sliding surface. Thereby, frictional force can be kept at a reduced state over a long term of operation, and the damping force of a hydraulic shock-absorber can be made into an extremely stabilized one.

Title: Removing method for residual aluminum in extrusion die
Inventor: ITO KATSUHISA
IPC: B21C35/06
Filed: 1988-02-24
Abstract: PURPOSE:To remove and to recover the Al remaining in a hollow part and recess by hanging the extrusion die having the residual Al into the molten salt bath containing mainly AlCl3 and clorids of alkali metals, etc., as the anode and by electrolyzing between the cathode. CONSTITUTION:By causing the DC current to flow to the extrusion die made of a tool steel having the residual Al in the direction to the anode in the molten salt bath, the residual Al is melted selectively. As for the molten salt bath, the molten salt containing AlCl3 especially the clorids of the alkali metal or alkaline earth metal are desirable. The anode current density is regulated to <=200mA/cm<2>. When it exceeds over this value, the die becomes soluble together with the Al to be undesirable. As a counter electrode, electric conductive materials such as metals or electronic conductive materials (bolides, etc.), are used, the Al dissolved from the anode into the molten salt is deposited to recover as solid metals by cathodic reduction. By this way, the residual Al in the die is easily removed and recovered and the dissolved solution is used repeatedly only supplying the lost quantity.
