IPC: B22F9/08
Filed: 1986-03-31
Abstract: PURPOSE:To prevent sticking of blocking to the top end part of a molten metal outflow cylinder by injecting part of high-pressure fluid and low-pressure fluid in parallel with the inside and outside surfaces of the molten metal outflow cylinder at the time of injecting the high-pressure fluid from diagonally above to the flow of the molten metal which flows downward in the molten metal outflow cylinder. CONSTITUTION:The molten metal 32 in a crucible 22 is allowed to flow downward through a molten metal protective cylinder 24 and the molten metal outflow cylinder 10. The relatively high-pressure fluid (gaseous nitrogen, etc.) is at the same time introduced from a high-pressure fluid introducing port 18 provided to a nozzle body 4 into a pressure chamber 16 and is injected diagonally downward so as to form a funnel shape from the 1st fluid ejection hole 21 toward the molten metal 32 which flows down from the top end of the molten metal outflow cylinder 10 to put the molten metal 32 into a mist state 40. Metallic powder is thus obtd. Part of the high-pressure fluid in the pressure chamber 16 is ejected from the 2nd fluid ejection hole 23 perpendicularly downward along the outside peripheral wall of the molten metal outflow cylinder 10; at the same time, the relatively low-pressure fluid introduced from an auxiliary fluid passage 30 is ejected perpendicularly downward from a fluid passage 26 along the inside peripheral wall of the molten metal outflow cylinder 10. The sticking of the blocking to the top end of the molten metal outflow part 10 is thereby prevented.

Title: Method and device for controlling step motor
Inventor: JIEIMUZU NOOMAN JIYAKUSON HOWA
IPC: H02P8/00
Filed: 1982-05-04
Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction. This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit. This data can be modified to suit the requirements of the stepper motor and load. Another program controls minimization of hysteresis by ensuring that each track on the disk is approached from the same direction and from the same previously energized set of windings. The microprocessor controls the direction of motion of the stepper motor and hence decides whether or not the read/write head should cross the desired track and return it to ensure uniformity of approach.

Filed: 1980-06-04
Abstract: PURPOSE:To prevent a decline of a copying speed, by detecting the size of a form which is used at the time of continuous copying, and changing over its copying cycle to one copying operation by one rotation of a photosensitive drum or to one copying operation by two rotations, in accordance with said detection result. CONSTITUTION:Copying paper P having different sizes is put in paper feed cassettes 141 and 142. Now, in case the paper feed cassette 141 has been selected, a switch 45 is closed, NOR circuits 46, 48 are not realized, and copying by the cassette 141 is executed. An original table 2 is returned by a signal from a return switch 4, a photosensitive drum 8 is stopped at a constant position at every copying operation, and one copying operation is executed at every one rotation of the drum 8. Subsequently, when a paper feed cassette 142 for large-sized paper has been selected, the switch 45 is opened, the NOR circuit 48 is realized, and when the continuous copying operation is executed, the original table 2 is returned by a signal from a return switch 5, and since the drum 8 is returnd to its constant position earlier than the original table 2 is returned to its original position, the drum 8 is made to run idle by one rotation. Accordingly, at every two rotations of the drum 8, one copying operation is executed.

Abstract: PURPOSE:To perform sealing without taking a time without exerting adverse effect on content, by heating a lid formed of a specific material by a high frequency induction heater and a main heater. CONSTITUTION:At a press station S1, a dish-shaped lid C2 is molded from a lid material made of a laminate, which is formed by applying a polyethylene layer to both surfaces of an aluminum foil, by pressing and, in a capping station S2, a container C1 is covered with said lid C2.
