Title: Magnetic disk driving device
Inventor: SUGANUMA YUJI
IPC: G11B25/04
Filed: 1991-03-14
Abstract: PURPOSE:To further reduce the magnetic disk driving device in thickness and weight compared with those in the conventional practice.

Title: Electrochemical processing method employing pulse current
Inventor: MAEDA RIYUUTAROU
IPC: B23H3/02
Filed: 1982-03-27
Abstract: PURPOSE:To achieve electrochemical processing with high processing speed, by setting the period of the pulse current suitably in accordance to the flow speed of electrolyte and the thickness of a work. CONSTITUTION:The interference occurring on the variation of the concentration or the temperature of the electrolytic product will show various modes depending on the pulse width, period, thickness of work, etc. When the peak M of the concentration gt exceeds over the limit concentration of the electrolytic product, it will hinder the working. The average level A of the concentration gt is proportional to the electrolyzing rate, and if other condition than the pulse current condition is same the average level A can be increased as M/A decreases. M/A will be the minimum level of 1 when the period T=1. Consequently the working condition may be selected such that the peak M of the concentration gt is low, and practically the working speed will be highest when the pulse period is selected to be T<1.
