Title: Electric resistance welding machine
Inventor: MIZUTANI KOU
IPC: B23K11/24
Filed: 1980-04-04
Abstract: PURPOSE: To make current supply and welding under a fixed condition for objects to be welded supplied at any time by conducting for a fixed time generated by a timing circuit by changing the polarity each time when an instruction signal for current supply is received.  
     CONSTITUTION: When a disk 24 rotates while receiving supply of a nail (a) from a chute 26, the nail (a) goes to electrodes 28, 28. At this time, a position detector 29 sends out a signal to start a timing circuit 11 and the output is applied to a driving circuit 6 through a gate 8. Then, transistors 1, 4 are turned on while the timing circuit makes timing action. By this, pulse current is supplied to transformer 5 and the current flows from a roller electrode 28 through the wire, nail (a) and wire to perform welding. When the next nail (a) approach the roller electrodes 28, 28, the position detector 29 sends out a signal and a flip-flop 10 becomes a set state. The timing circuits 12, 11 work similarly and the output is applied to a driving circuit 7 through a gate 9. Then, transistors 2, 3 turn on and the same pulse current opposite to the above-mentioned direction is supplied to the transformer 5 and welding is performed.

Title: Developing method of electrostatic latent image
Inventor: WADA KENICHI
IPC: G03G15/06
Filed: 1983-03-18
Abstract: PURPOSE:To obtain a uniform developed image without an uneveness of development by changing the voltage value of a developing bias periodically with the same frequency as an alternating magnetic field which is generated in a development region in accordance with the rotation of a magnetic roll and shifting its phase at a specific angle to the alternating magnetic field. CONSTITUTION:The voltage value of the developing bias is change perivdically at the same period as the alternating magnetic field, namely, with the same frequency as the alternating magnetic field and has the phase shifted from the alternating magnetic field by pi. Due to the fact that the periodic change has the phase shifted from the laternating magnetic field by pi, the voltage value is reduced if the intensity of the magnetic field in the development region is increased, and the voltage value is increased if this intensity is reduced. Therefore, respective development uneveness interfere with each other as shown by a broken line (g) and a solid line (h) in Fig. to act in directions where uneveness are cancelled. As the result, when a solid electrostatic latent image is developed by a developing device 20, a developed image having a uniform density as shown by a long and short dash alternating line (i) in Fig. is obtained by this action.

Title: Optical frequency stabilizer
Inventor: AKIYAMA KOJI
IPC: G02F2/00
Filed: 1988-02-29
Abstract: PURPOSE:To stabilize the optical frequency of an arbitrary incident laser beam and to make possible an output by a method wherein a change of the optical frequency of the incident laser beam is converted into a change of the amount of a transmitted light in an interferometer and a frequency shifter is driven in such a way as to cancel this.

A light to transmit a laser splitter 22 among the output lights of the AOM 21 becomes the output light of this stabilizer intact, the reflected light is incided in a beam splitter 23 and the transmitted light is incided in a Fabry-Perot etalon(FP) 24. The transmitted light transmitted the FP 24 is detected by a photodiode 25, the reflected light from the splitter 23 is detected by a photodiode 26 and the ratio of the transmitted light to the reflected light is computed by a divider 271 of a control device 27. A PID control circuit 272 controls the driving frequency fv of a VCO 29 in such a way that the output of the divider 271 has a prescribed constant value. Thereby, as there is no need to feedback to the current and the temperature of a light source, the optical frequency of an arbitrary laser beam can be stabilized.
