Title: Cooling structure of bottom electrode for resistance welding equipment
Inventor: NAKAJIMA SOUICHI
IPC: B23K11/36
Filed: 1995-04-19
Abstract: PURPOSE: To improve productivity by providing a flow hole for cooling water in an electrode base for holding a bottom electrode, cooling the bottom electrode and thereby greatly prolonging its service life. CONSTITUTION: In order to cool the bottom electrode 20, a flow hole 38 is pierced, which penetrates through the center of the electrode base 22 as well as the electrode block 28, as a passage for cooling water, and the cooling water coming out of the flow hole 32 of the electrode block 28 is passed to the flow hole 38 of the electrode base 22 by means of a hose 39. As a result, the electrode base 22 for the bottom electrode 20 not cooled by water heretofore is directly cooled, reising the cooling effect of the bottom electrode 20. Consequently, uneven wear, deformation, burr generation, etc., are reduced in the tip holding hole of the bottom electrode 20, greatly prolonging the service life of the bottom electrode 20 till it is exchanged, and enhancing productivity.

Title: Gate controller for waterway
Inventor: SUMIKURA SUSUMU
IPC: F03B15/04
Filed: 1978-07-31
Abstract: PURPOSE: To automatically control the opening and closing of gates of a reservoir and a settling pond, by applying opening-degree command signals for the gates in accordance with a changing instruction from the outside.  
     CONSTITUTION: When the instruction signal P 0  is entered into a gate controller X, function generators f 1 , f 2  produce the opening-degree command signals η 1 R, η 2 R for the gates of the reservoir and the settling pond. The signals η 1 R, η 2 R are applied to comparators A 1 , A 2  and compared with the true opening-degree signals η 1 , η 2  of the gates. The comparators A 1 , A 2  generate control signals F 1 X, F 2 X to regulate the opening and closing of the gates. Therefore, remote control of high reliability is enabled and the water level of the downstream settling pond can be limited within a prescribed range.
