Filed: 1988-12-22
Abstract: PURPOSE:To make a chip size small or to realize a high-density integration by a method wherein a common pad for characteristic test use is connected to two or more output terminals out of a plurality of output terminals via respective in-operation leakage-current limitation means. CONSTITUTION:A common pad 4 for characteristic test use is connected to output terminals 3-1 to 3-n via diodes 5-1 to 5-n as respective in-operation leakage-current limitation means. When a prescribed voltage is applied to the terminals 3-1 to 3-n, its potential is applied to the pad 4 at a characteristic test; a prescribed input signal IN is applied to a control part 1; for example, when an H-level potential is supplied to only a gate of a MOSFET 2-1, only the FET 2-1 is set to an ON state and other MOSFET's 2-2 to 2-n can be set to an OFF state. As a result, a drain current flows to only the FET 2-1 from the pad 4. This case is equivalent to a state that the pad 4 is connected to only the output terminal 3-1. When an electric current flowing via the pad 4 is measured, the MOSFET's 2-1 to 2-n can be tested one after another.

Abstract: PROBLEM TO BE SOLVED: To make quick control by judging whether a thermal image is kept at a stationary state or nonstationary state based on the relational expression between the measured values of the temperature of an object and the ambient temperature and temperature of the object and the ambient temperature obtained in advance. SOLUTION: A thermal image obtained by a temperature distribution measuring device at the time of heating is divided into six regions: the right and left of the head section of an occupant 4 (A1 , A2 ), the right and left of a clothes section (B1 , B2 ), and the right and left of the background including a seat (C1 , C2 ). The average temperature of the regions C1 , C2 , the average temperature of the regions A1 , B1 , the average temperature of the regions A2 , B2 , and the average temperature of the regions A1 , A2 , are calculated. The reference background average temperature in the ambient temperature, reference human body average temperature, and reference skin average temperature are obtained from the relational expression. Whether the thermal image is kept at a stationary state or nonstationary state is judged based on whether the relations between these temperatures and the allowable temperature width of the background average temperature, the allowable temperature width of the human body average temperature, and the allowable temperature width of the skin average temperature satisfy the prescribed equation or not.

SOLUTION: The crystal grain size in the tough pitch copper cast ingot is controlled so that the apparent quantity of Te per unit crystal grain boundary area in the tough pitch copper cast ingot becomes <=1.4×10<-7> (g/mm<2> ). The apparent quantity of Te [the apparent concn. of Te in the grain boundary: CTe (g/mm<2> )] is defined as CTe ≡ [The quantity of the cast ingot (g)/crystal grain boundary area (mm<2> )]. The hot-working such as rolling, forging, drawing, etc., is applied to this tough pitch copper cast ingot. The control of the crystal grain size in the tough pitch copper cast ingot is executed by casting of a molten tough pitch copper at a low temp. or giving an ultrasonic wave to the molten tough pitch copper at the time of casting or giving an electromagnetic- stirring to the molten tough pitch copper at the time of casting.  By this method, even if Te as impurity is contained, the hot-working cracking can be prevented.
