CONSTITUTION: This ultrasonic oscillator consists of a voltage control oscillator 1 of which the oscillation frequency is changed by the input signal value with the ultrasonic vibrator transducer 7 changed in power factor by a frequency as load, an output amplifier 3 which supplies electric power to the transducer 7 by amplifying the output signal of the oscillator 1, a phase difference detector 4 which detects the phase difference of the output voltage current of the amplifier 3 and the error amplifier 3 which amplifies the error between the phase difference of the output voltage current detected by the detector 4 and the set value of the phase difference. A phase locked loop is composed of the output signal of the amplifier 5 as an input signal to the oscillator 1.  The output of the proportional integrating amplifier is reset at the prescribed initial value in the state of the oscillation stop with the amplifier 5 as the proportional integrating amplifier of the prescribed time constant, by which the error amplification is started concurrently with the oscillation start.

IPC: H01L21/56
Filed: 1988-11-22
Abstract: PURPOSE:To separate a gate by a small force without remainder of burr by providing a protrusion protruding toward a downward direction on the lower face of a lead frame, and forming the outer wall of the protrusion in a sharp conical shape. CONSTITUTION:A gate 14 is formed on the lower face of a lead frame 10, and the connecting part 24 with a package 12 is formed in a slender pinch structure. A protrusion 18 is formed substantially in a conical shape protruding to the lower face of the frame 10. When a force B of a direction separating from the frame 10 is applied to the gate 14, the gate 14 is prevented from adhering to the lower face of the frame 10 due to the protrusion 18, and the gate 14 can be easily separated by a small force from the frame 10. Accordingly, the force B which operates on the gate 14 is concentrated to be operated at the part 24 of the pinch structure of the gate 14 to the package 12. Thus, the gate 14 is bent at the part 24 to separate the package 12 from the gate 14. In this manner, the gate 14 can be separated by the small force without remainder of burr.

IPC: H03K17/06
Filed: 1990-10-31
Abstract: PURPOSE: To maintain the constant output pressure of a MOS driver circuit regardless of the fluctuation in the supplied voltage by clamping the value of a boosted voltage at a voltage value set by opening a current passage to an output node from a boosting node when the boosted voltage value is higher than a set voltage value. CONSTITUTION: A clamper means CP is connected between a boosting node N1 and an output terminal OT and composed of a generating means GN for generating a reference voltage VR and a switching means SW for opening or closing a current passage. When the value (Vcc+α) of a boosted voltage applied across the node N1 is higher than a set voltage value, the clamper means CP clamps the boosted voltage at the set voltage value by making the current passage to the output terminal OT from the node N1 to be opened. Therefore, the noise produced from a power line and a grounding conductor when the output voltage of a MOS driver circuit fluctuates due to the fluctuation of the supplied voltage can be prevented.
