Title: Method and device for controlling resistance welding machine
Inventor: TAKAGI SEIJI
IPC: B23K11/24
Filed: 1982-01-08
Abstract: PURPOSE:To save labor and obtain welded products of good welding quality by watching generation of expulsion and surface flash through voltage between tips and decreasing the welding output to predtermined output condition at the time of generation of expulsion and surface flash. CONSTITUTION:A voltage groups temporary storing memory 4 stores each cycle of output voltge of a voltage extrantion and recognition circuit 3 between tips and averages the data of each cycle by a reference data averaging circuit 5, and stores as a group of averaged reference data by an averaged refeence data group storing circuit 6. The data at the time of deterioration of tips are extracted from the circuit 3 and stored by a deteriorated welding data group temporary storing memory 8. Only minimum value of the deterioration data is extracted by a minimum value extracting circuit 10 for deterioration data, and the data of each cycle are averaged by a deterioration data averaging circuit 9. An expulsion and surface flash recognizing circuit 7 recognizes generation of expulsion and surface flash and transmits a signal regarding the occurrence to a circuit 17. When expulsion and surface flash take place, welding output is decreased by an output controlling circuit.

Title: Hydraulic press
Inventor: KANAMARU NAONOBU
IPC: B30B15/06
Filed: 1981-01-14
Abstract: PURPOSE:To make tensile stress acting upon a cylinder constituting a ram device in a hydraulic press zero and to make the hydraulic press light in weight and high in accuracy by mounting and fixing said cylinder to the bottom surface of a crown. CONSTITUTION:In a hydraulic press, a flange part 22A of a cylindrical cylinder 22 is fixed by means of screws 21, 21A, and a fast feed cylinder 10 is secured to the bottom surface of a crown 4, whereby a ram device 20 is formed. When pressurized oil P3 is supplied and pressure for working product is exerted, the internal pressure of a pressurizing chamber rises. At this time, the stress in a longitudinal direction does not act as tensile stress upon the cylinder 22 because a spacing exists between the inside circumferential part 22D at the bottom end of the cylinder 22 and the outside circumferential part 11A at the top end of a hollow piston 11. Hence, the wall thickness of the cylinder 22 is made thin and the top area of the crown is made small; therefore, the press device of a small size, a light weight and high accuracy is obtained.

Title: Automatic film advancing device of camera
Inventor: TAMAMURA HIDEO
IPC: G03B17/00
Filed: 1981-01-13
Abstract: PURPOSE:To enable a photographer to continue photography while resetting a film advance without complicated operation when the interruption of a film advance is not caused by a fault of a camera, by coupling a resetting means with the releasing means of the camera. CONSTITUTION:When the interruption of a film advance is not caused by a fault of a camera, pressing a release button turns on a switch 310a, and a transistor (TR) 312 turns off. Consequently, a TR304 turns on to power up a motor MO, thereby making the film advance. The completion of the film advance changes the contact Sa of a switch S3 over to a Sc side, and when a TR319 turns off, the main capacitor of an electric flash is charged through its power-source circuit 200, switches S4 and S3, and a power source E, so that the camera is held in readiness for photography. Thus, resetting is enabled without complicate operation and the photography is continued.
