Title: Electrode pressure device for resistance spot welding
Inventor: FUNAI YOJI
IPC: B23K11/11
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To complete welding while squeezing deformation is kept low by arranging a spring mechanism having slit groove at an electrode position. SOLUTION: A spring mechanism 3, which generates a welding force by an elastic member of a slitting or slit groove, is arranged at the place nearest to an electrode 1. Setting of the welding force is executed through position control by a servo motor. An arm 4, while maintaining rigidity, is mounted to a pressure ram 5, a spring mechanism, which has an U shaped slit groove 6 to hold the electrode 1, is mounted to the tip of the arm. When the electrode 1 is pressurized to the arm, the spring mechanism 3 generates a reverse deflection to cancel the deflection of the electrode 1, that is, the deflection to stabilize a tip precision. By this method, a spatter at a weld zone is suppressed while the welding force is kept low.

Abstract: PURPOSE:To obtain a magnetic head having a narrow track and a narrow gap with high reliability by using an amorphous alloy as the material of a magnetic core to form a magnetic head through adhesion of glass. CONSTITUTION:A target composition Co81Nb13Zr6 is sputtered for about three hours on a substrate 1.

Filed: 1985-02-05
Abstract: PURPOSE:To perform heating with superior responsibility and energy utilization efficiency by irradiating the photosensitive layer of an electrophotographic sensitive body with light, and absorbing the light and heating the photosensitive layer directly. CONSTITUTION:The photosensitive body 11 is rotated, and then a light source 21 for heating the photosensitive layer is turned on to raise the temperature of the photosensitive layer up to necessary temperature by utilizing light from the light source. Then, a control mechanism turns on and off the light source 21 to hold the photosensitive layer at the necessary temperature and a copy is taken. The photosensitive layer is held at temperature which is 5 deg.C higher than the environmental temperature of a copying machine to prevent dew condensation on the surface of the photosensitive layer securely. When the in-use temperature of a photoconductive material which constitutes the photosensitive layer is higher than it, the temperature to be controlled is raised to the proper temperature more effectively.

Thereafter, with the pressure applied kept for a fixed time, a pressure test is carried out and if no abnormality is found, an electromag netic valve 29f is opened to reduce the pressure. Moreover, the 'Freon(R)' liquid sealed in the object 11 being tested is discharged into a drain tank 25 by an air pressure of an air compressor 24. The 'Freon(R)' liquid is returned to a liquid storage tank 26. But the internal structure of the object 11 being tested hinders complete discharge of the 'Freon(R)'. This requires the vacuum suction of the residue with the vacuum pump 21 and the residue of the 'Freon(R)' reaches the boiling point at the normal temperature to promote the evaporation speed thereby accomplishing the complete recovery of the liquid.

Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To realize stabilized jetting or flight of ink droplet by releasing or compensating for fluctuation in the heating value of a driver circuit or a piezoelectric element. SOLUTION: An input print drive signal (a) is amplified through a driver circuit 2 which controls the period or the passing interval of the drive signal (a) using a drive timing pulse (b) generated at a drive timing control section 4. An ink droplet is jetted from an ink jetting section 3 by an output from the driver circuit 2 produced based on the drive timing pulse (b). The drive timing pulse (b) is passed through an integrator 1 to produce a time average output which is expressed in terms of a heating value at the driver circuit 2 or the ink jetting section 3. Based on the heating value, width of the drive timing pulse (b) is varied within a range satisfying the ink jet conditions at the ink jetting section 3 to make constant the time average output.  According to the arrangement, fluctuation in the heating value of the driver circuit 2 or the piezoelectric element 3 can be suppressed even if the driving rate is varied depending on the pattern to be printed.
