Title: Insulating type direct current to direct current converter
Inventor: SAKIYAMA KOUJIROU
IPC: H03F9/00
Filed: 1982-12-27
Abstract: PURPOSE:To obtain an insulating type DC to DC converter for taking an accurate measurement of temperature, etc., by a thermocouple, etc., by using a power source for bias windings with saturable reactors as a variable constant current source. CONSTITUTION:The variable constant current source 8 which feeds currents to bias windings 7 and 7 with saturable reactors M2 and M3 is provided in order to set a specific operation point within a normal measurement range. An operational amplifier OP2 operates by this current source 8 so that the sum voltage of a voltage applied across a resistance R20 and a voltage drop across the winding resistance of the bias windings 7 and 7 is equal to a voltage drop across a resistance R17 for detecting a bias current. An operational amplifier OP3 is a differential amplifier with a gain 1, and said sum is inputted to the plus input terminal of the operational amplifier OP2. Consequently, a constant current circuit excites negative feedback windings 6 and 6 with a constant current to set an operation point within the measurement range, and the constant current is varied to move the operation point.

Title: Production of titanium powder
Inventor: IRIE TAKEFUMI
IPC: C22B34/12
Filed: 1994-08-31
Abstract: PURPOSE: To inexpensively obtain titanium powder having adequate purity and grain size distribution as a powder metallurgical raw material by changing the reaction conditions of titanium tetrachloride and metal magnesium in a crawl method. CONSTITUTION: The metal Mg raw material is packed into a reaction vessel 1 subjected to vacuum drying and gaseous Ar is introduced therein from a supply pipe 2 to maintain an inert atmosphere in the system after an upper cap 3 is closed. The reaction vessel 1 is then heated by a means 5 to melt the metal Mg and to form molten metal 7. The front end of the supply pipe 2 is then inserted therein and gaseous Ar is fed into the molten metal 7 to stir the molten metal; in succession, TiCl4 is fed alone or in accompaniment with the gaseous Ar therein via the supply pipe 2. This TiCl4 diffuses rapidly in the form of froth 8 and comes into efficient contact reaction with the metal Mg, thereby instantaneously forming a coexisting layer 6 where the titanium powder and MgCl2 powder coexist. The formed titanium powder settles by a sp. gr. difference.  The mixture where the titanium powder and the MgCl2 powder coexist is taken out and are separated and recovered.

IPC: G03D13/00
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To simply obtain a linear contact structure and to improve heat developing performance by projectingly providing pressing parts coming into linear contact with the outer periphery of a heating drum on one surface of a fixing plate oppositely facing the heating drum. SOLUTION: On a surface 61a oppositely facing a heating drum of a fixing plate 61, plural pressing parts 63 are formed. These pressing parts 63 can be formed in such a manner that for instance, a U-shaped notch opening is formed in the fixing plate 61 and elastic tongue pieces 67 making one side free ends are formed and curved in semicylindrical shapes around the center axis 68 in the width direction of the fixing plate 61 so as to be projected from the surface 61a oppositely facing the heating drum of the fixing plate 61. Therefore, a heat developable photosensitive material A inserted between the fixing plate 61 and the drum 33 comes into linear contact with the pressing parts 63 of the fixing plate 61 to be pressed on the drum 33. Therefore, heat radiation by thermal conduction is reduced. Thus, heating to the heat developable photosensitive material A is never made ununiform.
