Title: Welding system
Inventor: FUKUYAMA YASUNORI
IPC: B23K11/11
Filed: 1988-06-22
Abstract: PURPOSE:To weld the lead wire of an element to a terminal section while no tension is applied to the element so that disconnection of the lead wire can be prevented by measuring the welding position of the terminal section and welding the lead wire to the terminal section based on the measuring signal. CONSTITUTION:Before welding lead wires 4 of elements 3 to terminal pins 3 protruding from a parts main body 1, the positional deviation of the pins 2 and presence/absence of bends in the pins 2 are measured by bringing the measuring head 16a of a measuring instrument 16 into contact with the pins 2. Then a welding device 10 is actuated and the position of a reference electrode 11 is corrected before starting the welding of the lead wires 4 of the elements 3 to the terminal pins 2. The positional correction is performed by actuating a drive motor 15 based on the measuring signal of the instrument 16 and, after correction, the reference electrode 11 is brought into contact with each pin 2. Since the positional correction is already performed on the electrode 11, no load is applied to the terminal pins 2. In such state, the lead wires 4 are pressed against the pins 2 and, at the same time, welding is performed by conducting the reference electrode 11 with a movable electrode 12 by actuating the electrode 12. Therefore, the welding can be performed while no tension is applied to the elements 3.

Abstract: PURPOSE:To perform the communication among many nodes with high efficiency by securing the correspondence between a node address and an optical frequency so that no address is needed to a receiver of the transmission signal. CONSTITUTION:A frequency f1 is allocated to a node A.

At the same time, the oscillation frequency of a semiconductor laser 2 is also set at the frequency fR. Then the output of the filter 8 is monitored and an external modulator 3 is driven for transmission of information as long as no information is transferred to the node #R from another node.

Title: Gain control circuit
Inventor: OKADA HIROYUKI
IPC: H03G3/10
Filed: 1990-06-11
Abstract: PURPOSE:To obtain a sufficient attenuation with simple constitution by connecting a emitter of 1st and 2nd transistors (TRs) to a base of a differential pair TR respectively and providing a variable current means supplying a current to the emitter of the 2nd TR. CONSTITUTION:The gain of a differential amplifier is dependent on a difference of emitter voltages of 1st, 2nd TRs Q1, Q2 being components of an emitter follower. Since bases of the TRs Q1, Q2 are kept to the same level, the difference between the emitter voltages depends only on the ratio of emitter currents. The emitter current depends on TRs Q11, Q12 for a constant current source connecting to the emitter and a variable current source 15. When a current I3 flows, the conductivity of energizing of TRs Q4, Q5 is increased and the conductivity of TRs Q3, Q6 is decreased and the gain of the differential amplifier is reduced. When a diode D1 is energized, an attenuation as large as - 461dB is obtained at room temperature.
