IPC: B23K9/10
Filed: 1985-05-04
Abstract: PURPOSE:To control a flashing phenomenon, to eliminate the generation of spatters and to reduce the drastic man-hour curtailment in the following stage by passing the normal current after passing smaller current than the normal welding current value for the specified time at the welding starting time. CONSTITUTION:Timer contacts T21, T22 become in a closing state when a starting current AS is fed and the timer 22 reaches the set limit.

At the welding completion time all the circuits return in the original state and the welding motion is completed with the OFF operation of trigger switch 53. Due to the welding current at the welding start time being enabled to be limited to the small current less than the prescribed value there are less generations of spatters and good arc welding can be performed for drastic reduction in the following process.

Title: Discriminating method for return signal in multiplex transmission
Inventor: FUJIKI HITOSHI
IPC: H04B17/309
Filed: 1986-04-24
Abstract: PURPOSE:To discriminate the level of a return signal without being affected by the distortion, or the delay, etc., of a waveform, by taking a logical product of the output of a sampling pulse generated with a timing coinciding with a synchronizing signal, and the return signal returning from a reception side. CONSTITUTION:A return signal RD returned from a repeater is waveform- arranged at a waveform arranging circuit ST, and is inverted by an inversion circuit NOT, and the logical product output of the sampling pulse can be obtained. The sampling pulse sets, for example, the leading edge point of a synchronous pulse as a start point, and is outputted as a pulse string between 500musec-900musec. Thus, when a reference data is stored, a discriminating pulse can be obtained at every sending of the return signal from the repeater, and it is compared with a reference discriminating pulse in order, thereby, the level of a return pulse is discriminated.

IPC: H04N3/24
Filed: 1982-06-04
Abstract: PURPOSE:To obtain a pulse which blanks the blanking period completely with a simple circuit, by slicing an S-shaped correcting voltage of a deflecting current at a pulse width of the blanking period. CONSTITUTION:After a DC component of a correcting voltage (d) is eliminated at a capacitor C4, the correcting voltage (d) is formed into a suitable level at resistors R1, R2 and applied to a comparator 5. On the other hand, a voltage value of a power supply B2 and a resistance value of resistors R3, R4 are set to those with which the waveform of the voltage (d) eliminated for the DC component is sliced at the blanking period in the deflecting current (c), i.e., a pulse width of a flyback pulse at a potential V2 of a connecting point (b) between the resistors R3 and R4. Thus, the voltage (d) eliminated for the DC component is sliced at a level of the potential V2 at the comparator 5 and a blanking pulse (e) is extracted from the comparator 5. As a result, the blanking period is blanked almost completely and no noise is generated on a reproduced screen.
