Title: Gas permeating film
Inventor: FURUYA CHOICHI
IPC: H01M4/96
Filed: 1987-08-07
Abstract: PURPOSE:To keep off any penetration leakage of liquid without damaging the functions of a gas permeating film by installing a fluorinated resin rich layer on a film surface of a gas permeating layer consisting of a mixture of water-repellent carbon black and polytetrafluoroethylene. CONSTITUTION:A polytetrafluoroethylene rich layer 1b is installed on one surface of a gas permeating layer 1a made up of heating and sintering water- repellent carbon black and polytetrafluoroethylene into a mixed sheet form, thereby forming a gas permeating film. 1. When this film 1 is used for a cathode plate of a cell, by way of example, even if an electrolyte comes to be penetrated because of loss water-repellency in the layer 1a, it is stopped by the layer 1b so that any solution can be prevented from leaking in the backside. In addition, this layer 1b will not come to any resistance against gas permeation, so that the functions of the film 1 are maintained. With this constitution, any penetration leakage of liquid is prevented from occurring without damaging the functions of the permeating film and, what is more, durability and prolonged service life are well promoted.

Abstract: PURPOSE:To facilitate the accurate adjustment of cutting feed amount by synchronously rotating outer and inner spindles with a rotation control section via respective rotation mechanisms thereby changing the rotary speed of the outer spindle in accordance with the amount of exposure of a cutting edge of a tool. CONSTITUTION:A rotation control section 1 controls the rotation of motors 3, 4 and, when no movement commands are inputted, causes an outer spindle 5 and an inner spindle 6 to rotate synchronously with the rotary speed ratio of 1:1. The center of the outer spindle 5 and the center of the inner spindle 6 are displaced and a tool is attached in a tapered hole 9 in the inner spindle 6. In the case the cutting feed amount is to be changed during machining, an input signal for changing the number of relative rotation is given from the rotation control section 1 to the inner spindle 6 so that the motor rotates by the amount given to change the cutting feed amount. The number of relative rotation is changed with the information value of a movement command section 2. Since the control is performed electrically, there are no mechanical losses and therefore accurate position adjustment is possible.
