Inventor: JINNO KEIJIROU
IPC: H03D3/16
Filed: 1983-04-13
Abstract: PURPOSE:To obtain a signal, which has the phase shifted at about 90 deg., without adjusting by supplying an AC input voltage to the connection point between two resistances and taking out an output voltage from an operational amplifier. CONSTITUTION:Transistors(TR) 49 and 52 are so arranged that they constitute current mirror circuits together with TRs 41 and 42, and TRs 50 and 51 constitute a current mirror circuit also. An intermediate frequency signal is transmitted to TRs 47 and 48 constituting a differential amplifier through TRs 32 and 33 without phase shift. The output of the TR32 is transmitted to a phase circuit, and the output of a TR38 which is subjected to phase shift is connected to bases of TRs 43-46. Consequently, the original intermediate frequency signal is multiplied by the phase-shifted intermediate frequency signal in a multiplying circuit to perform FM demodulation. The demodulated signal is outputted as an audio output through a resistance 76 and a capacitor 77 constituting a low pass filter.

IPC: H01L21/607
Filed: 1985-03-28
Abstract: PURPOSE:To enable a wire to be cut off without any elongation thereof when it is postbonded, by inputting supersonic waves to a contact bonding head while at the same time sending the input signal also to a solenoid for actuating a clamp lever so that the solenoid is turned ON at a time from the start of the input of the supersonic waves up to the end thereof and the wire is pulled and cut off by means of the clamp lever thus actuated. CONSTITUTION:Supersonic waves are inputted to a contact bonding head 25 for 150 milliseconds for example, while a signal from an encoder is simultaneously inputted to a solenoid 28 of a clamp lever 27 through a delay circuit with a delay of 40 milliseconds from the input of the supersonic waves. The clamp lever 27 is thereby moved as indicated by the dot-and-dush line from the position as indicated by the solid line. Thus, a wire 24 clamped by the clamp lever is pulled and cut off. For postbonding the wire 24 to a lead 26, the supersonic waves are inputted to the contact bonding head 25 and the solenoid 28 is turned ON with a time delay of 40 milliseconds from the input so that the wire 24 is pulled by the clamp lever 27. Since the wire 24 is pulled under a condition that it can be well fused off by the contact bonding head 25, it can be cut off without elongation.
