Title: Sealed battery
Inventor: TANAKA TAKASHI
IPC: H01M2/12
Filed: 1988-02-04
Abstract: PURPOSE:To stabilize operation pressure of a safety valve by applying the circumference of the valve to the inner surface of an anode terminal, and positioning the valve coaxially with a valve hole so as to seal the valve hole in a seal port plate with the center bottom of the valve at the time. CONSTITUTION:A cut is formed from the lower bottom of a protruding part of an anode terminal 1 to its flange part for forming an exhaust port 1a. A valve body 3 of rubber of a cylindrical form is applied to the inner surface of the terminal 1. This valve body 3 is positioned coaxially with a valve hole 2a, so the center bottom of the valve body 3 seals and closes the valve hole 2a in a seal port plate 2. The seal port plate 2 is welded to the terminal 1 at the flange part, holding the valve body 3 in an inner space composed of the seal port plate 2 and the terminal 1. A thus composed safety valve body 4 is fixed at a battery cell through an insulating packing to compose a sealed battery. Operation of the safety valve of the battery can thus be stabilized, while no problems occur concerning insertion of the valve body 3.

IPC: H01L21/302
Filed: 1978-03-06
Abstract: PURPOSE: To produce a selective etching mask for semiconductors, which is formed easily without requiring a high temperature, by using an Al evaporation film.  
     CONSTITUTION: Though Al is soaked in etching liquid of nitric acid-fluoric acid- acetic acid or hydrogen, the etching speed is considerably low in comparison with Si.

Title: Bush type vibration control device
Inventor: KOJIMA HIROSHI
IPC: F16F13/00
Filed: 1993-02-15
Abstract: PURPOSE:To provide a liquid filling bush type vibration control device that is simple in structure and makes a spring constant variable. CONSTITUTION:A pair of liquid chambers 20 and 20 are installed in space between an inner cylinder 12 and an outer cylinder 14 in holding this inner cylinder between. A rotor 26 is rotatably installed in the inner cylinder 12, and when a circular hole 42 of the inner cylinder 12 and another circular hole 40 of the rotor are opposed to each other, the paired liquid chambers 20 themselves are interconnected to each other, but in a state that both these circular holes 42 and 40 are not opposed, these paired liquid chambers 20 themselves are made so as not to be interconnected. In the case where these liquid cars 20 are interconnected to each other, the liquid chambers can be freely extended or contracted and a spring constant in a direction connecting an interval between the liquid chambers becomes low. In the case where these paired liquid chambers 20 are not interconnected to each other, expansion or contraction of these chamber 20 is restricted, so that the spring constant becomes higher. When this bush type vibration isolator is used as a suspension bush for an automobile, at the time of turning, the spring constant is heightened, improving the extent of steering stability, and the spring constant is lowered to sane extent at the time of traveling on a rough road, thereby making the extent of vibro-absorbency improvable.

Abstract: PROBLEM TO BE SOLVED: To improve work efficiency and to shorten transfer time between a substrate and a tray by controlling a loading/unloading head, a robot main body and the operation of the loading/unloading head. SOLUTION: A control panel 30 is fixed to a transparent cover 29 on an installation stand 11 and a sequence controller controls the operation of the robot main body 24 and the loading/unloading head 25. A control part 70 controlling the operation of the whole device is stored and the control panel 30 is connected to the control part 70.

Since the loading/unloading head 25 simultaneously transfers three IC 13, the number of times that the loading/unloading head 25 reciprocates between the substrate 1 and the tray 4 can be reduced. Then, work efficiency improves and work time can be shortened.
