Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To inexpensively produce foams of high melting materials (metals and ceramics) having excellent lightness in weight, air permeability and filtration characteristic and directional pores. SOLUTION: Metals or ceramics are melted in a melting furnace to obtain molten metal. Gases consisting of at least one kind of gases among gaseous H, N and O, are applied to this molten metal and the total pressure 1 to 500atm of the gases is applied thereto to dissolve the gases. Casting molds are preheated to a range of the respective. m.p. of the metals or ceramics ±50 deg.C. While the total pressure of the gases applied to the molten metal is maintained, the molten metal is poured into the preheated casting molds. While the total pressure of the gases applied to the molten metal is maintained, the heat extraction from the upper surface and flanks of the casting molds is prevented and the heat is extracted from the lower surface alone to allow the molten metal to solidify. The molten metal is unidirectionally solidified to the foam which extends upward, has the directional pores of a minor diameter of 5μm to 10mm and porosity of 50 to 98%. Further, fine particles to constitute the nuclei for foaming are added to the molten metal.

Abstract: PURPOSE:To decrease the ON-resistance of a MOSFET and to suppress the voltage drop, power loss and heat dissipation by connecting a collector and an emitter of a photodetection transistor(TR) between a gate terminal and a source terminal of the MOSFET. CONSTITUTION:When a DC voltage is applied between input terminals 1, 2 and a DC voltage as the input signal is not applied between input terminals 1, 8, a 1st LED 3 is driven for stimulation and a 2nd LED 9 is not driven for stimulation. Then in the mode as above, an electromotive force generating element array 4 generates an electromotive force and a photodetection TR 19 is turned off, then a MOSFET 5 is turned on to close output terminals 6 and 7. When both the LEDs 3, 9 are driven for stimulation, the photodetection TR 10 is turned on, the FET 5 is turned off to open the circuit connected between the terminals 6, 7. Since the LED 3 is in the state of non-emitting stimulation when no DC voltage is applied between the terminals 1 and 2, even if no input signal is applied to the terminals 1, 8, the FET 5 is turned off to open the circuit connected between the terminals 6, 7.
