Title: Iron-based electroplating method
Inventor: MATSUBARA SHIGEO
IPC: C25D3/20
Filed: 1988-04-13
Abstract: PURPOSE:To continuously obtain a good iron-based electroplating by discharging a gas generated in the anode chamber of a plating bath by the circulation of a plating soln. sent from the plating bath to an electrolytic reduction tank to increase the Fe ion concn. in the plating soln. CONSTITUTION:The plating soln. is circulated at an ordinary flow velocity in a cathode chamber 4 of an electrolytic bath 1. The flow velocity of the plating soln. is controlled at the initial stage of plating to increase the Fe<3+> ion concn. When the Fe<3+> ion concn. is increased, the opening degree of a valve provided to a pipeline between the anode chamber 3 of the electrolytic bath 1 and the electrolytic reduction tank 6 is adjusted to circulate the plating soln. so that the gas generated from the anode surface is discharged. As a result, a concd. plating soln. wherein the Fe<3+> ion concn. is held at <=50% of the total Fe ion concn. is obtained. The plating soln. is supplied to the cathode chamber 8 of the electrolytic reduction tank 6, and electrolytically reduced to such an extent that the Fe<3+> ion concn. is decreased to >=15% of the total Fe ion concn.

Title: Hydraulic operation type impact device
Inventor: NIEMI ILKKA
IPC: E21C/
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of an impact device more than usual by setting the moving speed of an impact piston and a control valve in inverse proportion to the ratio of difference of the cross-sectional area of respective parts of the piston to the total area of pressure surfaces of the control valve opposed to a closed space. SOLUTION: The total area of pressure surfaces of a control valve opposed to a closed space is set to larger than the difference between the inside area of the impact piston and the area of a part having the maximum diameter opposed to the closed space so that an impact piston can move quicker than the control valve and escape from a space A' provided in the control valve. In this case, the moving speed of the impact piston is already large, the piston continues the downward acceleration movement, a piston guide part A is brought in contact with a succeeding-tool appearing from a part A' of the control board 6 to open the connection from the pressure space A" to a space in the lower side of the control valve 6. The valve stops at the lower position, while the impact piston continues to move downward.  When the control valve and the impact piston simultaneously move downward, high-pressure fluid operates both of the impact pressure surface 2 of the impact piston and the upper-side pressure surface of the control valve.
