Title: X-ray automatic exposure control device
Inventor: KATAYAMA TOMOMI
IPC: H05G1/44
Filed: 1989-01-31
Abstract: PURPOSE:To keep constant the reference value for specifying the film concentration regardless of varying tube voltage by using a photo-receiving element to constitute a photo-coupler as an integral resistance of an integrating device to sense the does of penetrative X-rays, and by controlling the intensity in light emission from photo-emitting element in accordance with the tube voltage. CONSTITUTION:The resistance value of a CdS cell of a photo-coupler P consisting of a CdS cell (photo-receiving element) and a light emitting diode LED (photo-emitting element) varies in compliance with the intensity in light emission from the LED, i.e. the current value of LED. The LED is connected with a photo-coupler current control circuit P.C. which controls the supply current to the LED in conformity to the tube voltage signal. Consequently a lower tube voltage provides an earlier time for attaining the reference voltage by the integral voltage to result in a correction so that the X-rays are shut earlier. The reference voltage to specify the film concentration supplied to one of the input ports of a comparator 18 is set to a certain voltage which ensures stable performance of automatic exposure control.

Title: Automatic duty setting circuit
Inventor: OGAMI CHOJI
IPC: H03K5/156
Filed: 1988-02-02
Abstract: PURPOSE:To automatically obtain rectangular waves of 50% in duty by impressing the output of a non-inversional logic circuit which inputs the output of an inversional logic circuit, to the input terminal of which a capacitor is connected, upon the input terminal of the inversional logic circuit through a charging/discharging circuit composed of resistors and a capacitor. CONSTITUTION:Since waves or triangle waves are impressed upon an input terminal 101. The sine waves or triangle waves are inputted to the input terminal of an inversional logic circuit 103 through a capacitor 102 and rectangular waves of 50% in duty are obtained on the output side of the circuit 103. Namely, when the output signal of the circuit 103 is impressed upon the input of a non- inversional logic circuit 104, pulse signals having the same duty are obtained as the output of the circuit 104. When the output signals are supplied to a charging/discharging circuit composed of resistors 105 and a capacitor 106, a voltage which is proportional to the duty of aimed rectangular wave signals is obtained across both ends of the capacitor 106. When the voltage is applied across the input terminal of the circuit 103 through a resistor 108, the center potential of the inputted sine or triangle waves can be fluctuated proportionally to the duty of the aimed rectangular wave signals.

Title: Refractory mold for padding metal
Inventor: KONDO YOSHIYUKI
IPC: B22D19/16
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the lowering of water cooling effect in a refractory mold for padding a metal and the abnormal erosion of the refractory on molten metal surface by arranging a material having high erosion resistance in the interface between the molten metal surface and the solidified surface of the metal and a material having high conductivity on the solidified surface. SOLUTION: As the material 1 having high erosion resistance, a refractory aggregate for 10-28wt.% at least one kind of natural graphite or artificial graphite and the balance Al2 O3 , MgO, ZrO2 and SiC, etc., is used. As the material 2 having high heat conductivity, a refractory aggregate of 30-90wt.% at least one kind of the natural graphite or the artificial graphite and the balance Al2 O3 , MgO, ZrO2 and SiC, etc., is used. Further, the material having high erosion resistance and the material having high heat conductivity are separately manufactured to execute the joint with mortar 3. Since the graphite is difficult-to-wet with the molten metal, it shows such larger effect as to restrain the infiltration of molten metal.  Further, since the graphite has extremely high heat conductive in comparison with the other refractory aggregates, it is said that the graphite is the effective raw material as the refractory mold, but the graphite content in the refractory on the molten metal surface is necessary to sufficiently consider.
