Title: Magnetic drive arc welding method
Inventor: SAITOU AKIHIRO
IPC: B23K9/08
Filed: 1979-04-02
Abstract: PURPOSE: To obtain the weld zone of stable fusion-welded condition by intermittently superposing large current to arc current for a short time to apply spot-like anode arcing points or cathode arcing points evenly to the entire surface of the weld line  at the arc driving.  
     CONSTITUTION: The arcing points of the anode and cathode formed by the arc column generated on the weld line are made to the spot-like uniform shape, area and pitch. Namely, in order to determine the pitch and form the spot-form maximum points surely by defining the time lapse when the arc column elongates and grows, instantaneous large current is applied to enhance directivity and melt the entire part evnely, whereby the stable and sufficient fusion-welded zone is obtained. Namely, when the pulse current of, e.g., triangular wave, is superposed in kHz unit to the base current, the arcing point is surely formed in the minimum voltage position by the peak current instantaneously applied first and the arc is generated. The area thereof is increased with time. The acting force for bending the arc column to bow form by magnetic field at this time is hardly affetced at the end part of the triangular wave of a short time lapse when the magnetic blow is bent and grows, thus the spot-like stable maximum points grow.

Filed: 1980-03-31
Abstract: PURPOSE:To perform stable developing at high speed by applying AC voltage during developing in developing using the one-component insulation characteristic magnetic toner. CONSTITUTION:A magnetic roll 43 and a nonmagnetic cylindrical sleeve 42 are both rotated in the (x) direction in such a manner that the ratio of the number of revolutions is kept at >=20, whereby the insulating magnetic toner (10<12>-10<16>OMEGAcm  in a DC electric field of 10,000V/cm) is conveyed in the (y) direction and a toner layer 4 of a constant thickness is formed from between a photoreceptor 1 and a  sleeve 42. It is necessary to increase the number of revolutions of a magnet in the case of performing development at an ordinary high speed, but good developing is made possible by applying AC voltage of more than 1/0.3 times the moving speed (v) (mm./sec) of the photoreceptor even if the number of revolutions of the magnetic roll is reduced to >=1/2. It is preferable that the peak-to-peak value of the AC voltage is >=1.5 times and <=4 times the dark potential of the latent image.

Filed: 1981-03-20
Abstract: PURPOSE:To make capacitance of the source and drain against a substrate smaller and to make integration density higher by improvement in impurity distribution right under the gate of a MOS transistor. CONSTITUTION:A gate oxide layer 3 and polycrystalline silicon layer 6 are formed on a p type region 10 which has been formed on a P<-> silicon substrate. By using this gate region 3, 6 as a mask, n type regions 14, 15 of lower concentration are formed. At the same time, in the overlapped areas with the p type regions 10 provided are regions 12 which are of lower effective impurity concentration. Next, an oxide layer 13 is formed on the surface by oxidizing treatment. After this oxide layer 13 is removed, the N<+> source 16 and drain 17 are then produced using the gate region 3, 6 as a mask which has become smaller than its original state. By such process, the region in inverted-T shape which is of relatively higher impurity concentration and of the same conductivity type as the semiconductor substrate can be formed right under the gate insulating layer.
