Title: Arc stud type welding method
Inventor: SCHWIETE BERND
IPC: B23K9/00
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To perform the welding in an arc stud welding by detecting stains on the surface of a work piece, and sufficiently cleaning the surface. SOLUTION: When the main current I is fed by the start signal to energize the electric arc, the voltage U of the arc (or its means voltage Uavg ) is measured with the intervals Δtm . When the measured voltage U is much larger than the threshold voltage Us , the surface stain is judged to be present, and the stain is cleaned by superposing the positive purifying pulse on the main current I. Measurement of the voltage U and feeding of the purifying pulse are repeated, and the stain is judged to be eliminated when the voltage U is not more than the threshold voltage Us . The main current I is increased and kept, and the actual welding process is performed. The number of repetition may be limited by the feeding number of the purifying pulse.

Abstract: PURPOSE: In an electrical power device for heating welding wire, to manufacture a power device which does not require a transformer with constant voltage characteristic, is cheap in cost and excellent in manipulation by connecting a resistor between terminals of the output part of a transformer with constant current characteristic.  
     CONSTITUTION: In a power device by which a deposite pool is formed on a parent substance 8 through wire 7, a transformer 1 with constant current characteristic instead of conventional constant voltage characteristic is equipped and a resistor is set between terminals of the output part of the transformer 1. As a result, the maximum output voltage of the transformer can be changed by the output current. In other words, the maximum output voltage of the transformer 1 for the resistance R 3  and output current I 0  in the resistor 15 is determined by R 3  if the current is I 0 . The value of resistance R 3  is determined to keep the maximum voltage where arc is not generated in the gap between the wire 7 and the parent substance 8 when a conventional unsteady state appear. In this method uniformity of welded beads can be obtained by a cheap device.

Title: Rotational vibration measurement
Inventor: TANAKA SHIGEO
IPC: G01M99/00
Filed: 1982-06-08
Abstract: PURPOSE:To reduce the required measuring days and costs by housing one set of a sample rotor into a heater box adapted to be made vacuum. CONSTITUTION:A sample rotor 1 with a rotary vane 2, a bearing 4, a rotating motor 5 and a slipping 6 are housed in a heater box 3 forming a closed container. After the box 3 is made vacuous with a vacuum pump 7, the motor 5 is driven to turn the sample rotor 1. The sample rotor 1 is rotated at the max. running revolution and then, air is discharged toward the rotary vane 2 from a vibration nozzle 9. Vibration generated from the vane 2 is applied to a strain gauge and detected through the slipping 6. With the introduction of air, the pressure in the box 3 rises gradually and the speed of the rotor 1 reduces due to air loss thereby eliminating the need for positively changing the revolution of the motor 5. This lowers the possibility of damaging the measuring lead to reduce the required measuring days and costs.

Title: Electrophotographic sensitive body
Inventor: KARAKIDA KENICHI
IPC: G03G5/14
Filed: 1983-06-03
Abstract: PURPOSE:To provide a photosensitive body which has excellent resolving power and cleanability, has a large allowance for toner concn. and permits formation of a copy free from a photographic fog with a photosensitive body for electrophotography which has a protective layer dispersed with pulverous metallic oxide layer in a binder resin as a surface layer by using the pulverous metallic oxide powder having a specific grain size. CONSTITUTION:A protective layer is formed on a photosensitive layer by coating a soln. dispersed with pulverous metallic oxide powder in a binder resin on said layer or forming the soln. into a film shape and adhering the film thereon. The protective layer is so formed that the metallic oxide particles having <=0.3mum average grain size are dispersed in the binder resin and that particle flocs of >=2mum size do not substantially exist therein in the dispersed state. Such intermediate layer has high transparency and is outstanding in terms of surface smoothness as well. A photosensitive body having such protective layer has consequently excellent resolving power and cleanability and a large allowance for toner conc. Since the decrease in photosensitivity is less than that of the photosensitive body having no protective layer, the deterioration in image quality such as a photographic fog is obviated. Since the photosensitive layer has the protective layer having high transparency, the protective film can be formed to a relatively large film thickness. The photosensitive body which has high mechanical strength and is free from external influence of temp., humidity, etc. is thus obtd.

The solution is fractionally crystallized to obtain a bisphenol and a first solvent solution, and then the bisphenol is recrystallized by a second solvent. The first solvent solution is combined with the secondary solvent solution used here, and the bisphenol is recrystallized from an alcohol to obtain a bisphenol of formula I or formula II (with a purity of about 95%). From the compound of formula I or formula II, a polycarbonate comprising at least one structural unit of formula V or formula VI is obtained.
