Title: Method for regenerating aluminum alloy
Inventor: KANAZAWA EIJI
IPC: C22B21/06
Filed: 1987-08-07
Abstract: PURPOSE:To effectively regenerate an Al alloy without using harmful gases, by adding alkali silicide of low m.p. to a molten Al alloy containing Mg and Ca and then removing MgO and CaO formed by the reaction. CONSTITUTION:Either or both of Na2CO3 and K2CO3 are mixed with silica sand, and the resulting mixture is fired so as to be formed into vitreous alkali silicide of low m.p. This alkali silicide is pulverized and formed into a flux together with other solvents, which is added to molten Al principally composed of Al scrap containing Mg and Ca. Since MgO and CaO formed as reaction proceeds rise to the surface of the molten metal in the form of slag, this slag is removed. By this method, the Al alloy can be regenerated with superior workability at the temp. of the molten Al.

IPC: B23K11/14
Filed: 1986-08-25
Abstract: PURPOSE:To decrease the generation of weld beads on a rod by executing welding in an inert gaseous atmosphere at the time of producing the piston rod by friction welding or projection welding of balls to both ends of the rod. CONSTITUTION:The ball 25 is housed in a recess 29 of a ball holding base 27 and air is sucked from an air vent hole 31 to fix the ball 25 to the recess 29. After the rod 21 is supported to a chuck 23, holding base 27 is brought near to the rod and the balls 25 and held to both ends of the rod 21. The chuck 23 is rotated in this state at a high speed to weld the balls 25 frictionally to both ends of the rod 21. The welding is executed in the inert gaseous atmosphere and the weld beads 25 of a min length are formed to both ends of the rod 21. The generation of the weld beads to be formed at the rod is thereby decreased.

Title: Type wheel positioning device
Inventor: WATABE NOBUO
IPC: B41J25/24
Filed: 1982-11-12
Abstract: PURPOSE:To make the installation of a print wheel to an apparatus easier by such an arrangement wherein plural abnormally shaped projections are provided on a base seat and holes which couple with those projections are provided on the bottom surface of a print wheel and a permanent magnet is also utilized. CONSTITUTION:Since attraction force between a permanent magnet 7 and a magnetic object 8 on the bottom surface of a print wheel is made smaller by a gap (a), when a base seat 4 is caused to rotate by a drive motor 5, relative rotational motion is generated between a print wheel 9 and the base seat 4. By this relative rotational motion, positioning holes 1', 2', 3' of the print wheel 9 eventually coincide and couple with projections 1, 2, 3 on the base seat 4 respectively, and at same time, the bottom surface of the print wheel 9 is caused to closely contact with the base seat 4 by the attraction force of the permanent magnet 7. The reason why plural pieces of differently shaped projection are provided on the base seat 4 is that the print wheel can be prevented from being slanted when it is not located at a specified position.

Abstract: PROBLEM TO BE SOLVED: To make multi-valued data recordable by storing the charge of the amount made to corresponding to the impression voltage of a gate electrode on a nitride film at the time of data wiring and reading the output made to correspond to the stored charge amount at the time of data reading as multi-valued data. SOLUTION: At the time of a write-in, potentials of a substrate 11 and a source region 12 are made to be 0 V and a prescribed high voltage for write-in is impressed on a cell gate 22 as a voltage for writing 0 in which electrons are stored on a nitride film 20 in a drain region 13. Here, when the impression voltage on the gate 22 is gradually raised, a wedge shaped channel 26 is formed on the surface region of the substrate 11 being downward of a side wall 15 and electrons are generated from its tip part and the electrons being one part of the electrons pass an insulating film 19 by the electric field effect of the gate 22 to be stored on the film 20. Consequently, stored amounts are proportional to impression voltages. Moreover, at the time of reading data from the cell on which plural data are written, the reading of multi-valued data is made possible by comparing the output voltage obtained by changing of gate voltages with plural reference voltages and by detecting by which gate voltage the output is generated.

Title: Amplifying device
Inventor: EMURA MINORU
IPC: H03F3/217
Filed: 1982-11-12
Abstract: PURPOSE:To eliminate the effect of variation of the power supply voltage or the ambient temperature by storing the positive or negative electric energy of reducing the stored energy by the level of the input electric signal. CONSTITUTION:When a power supply switch circuit 1 is switched to the +Es side, the electric charge is charged to a capacitor C22 from the power supply +Es. This voltage is divided by a voltage divider 4 and applied to a plus input terminal of a voltage comparator 5. The comparator 5 compares the input voltage applied to a minus terminal with the voltage of the plus input terminal. Then the comparator 5 applies a switch signal (c) of H level to the circuit 1 if the former voltage is lower than the latter one. The circuit 1 is switched to the -Es side when the signal (c) is set at H level and then to the +Es side when the signal (c) is set at L level respectively. Then the electric charge of the C22 is gradually discharged in the former case and then charged gradually in the latter case respectively. Therefore, the both-terminal voltage of the C22 is equal to the sum of the amplified input voltage and the ripple components generated by charging/discharging of the C22. In such a constitution of circuit, no active element is included as an amplifying element.
