Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by providing a constant current source which is equal to current between each transistor drain and ground when common input terminal applied voltage from each gate of P and NMOS transistors is equal to operation point voltage. SOLUTION: When half of operation point voltage Vso of input signal voltage Vs of an input terminal Ti on an output stage 2 and power supply voltage Vdd are inputted, Vdd/2 is inputted to the gate of an NMOS transistor Qn1, and corresponding current flows through between drain and source.

Abstract: PURPOSE:To uniformly heat the entire surface of a substrate by a heat transferring system by placing a substrate applied with pastelike solder on a flexible thin film directly put on the surface of a fluidized body housed in a tank and heated to a prescribed temperature. CONSTITUTION:At the time of soldering pastelike solder on a substrate 5 by reflowing, the substrate 5 is placed on a heat resisting film 3 on the upper surface of a tank by means of a holding head 6 while the substrate 5 is attracted by suction to the sucking nozzle 7 of the head 6 and slightly pressed against the film 3. Then the lower surface of the substrate 5 is brought into close contact with the film 3 without clearance even when the substrate 5 is somewhat bent due to the flexibility of the film 3 and the entire surface of the substrate 5 is uniformly heated through the film 3 by means of melted solder 2 heat to a prescribed temperature. Since the melted solder 2 is in a liquid state, the temperature distribution of the solder 2 can be uniformized easily and, by press-contacting the lower surface of the substrate 5 against the thin heat resisting film 3, the heat of the solder 2 is uniformly transferred to the substrate 5 and the substrate 5 can be heated effectively to a uniform temperature.
