IPC: B41J11/34
Filed: 1989-05-23
Abstract: PURPOSE:To remove slack of paper by a method wherein a plate spring is pressed onto the paper with a switching lever. CONSTITUTION:A medium 2 is inserted in a medium insertion direction (a) and is wound around a pin tractor 4 through a printing part 13. When a switching lever 3 moves in a moving direction (b) an arm 11 is moved in a moving direction (c) with a bar 10 and a shaft 5 moves to raise a plate spring 1 coming in contact with the shaft 5 like a pressure part A. When the switching lever 3 moves in a moving direction (d), the arm 11 is moved in a moving direction (e) with the bar 10, and a shaft 5 is moved. Therefore, the shaft 5 loses force for raising the plate spring 1, and the plate spring 1 presses down the medium 2. Further, a pressure roller 6 is moved in a moving direction (f) with a support bar 12 connected to the switching lever 3, and a gap between the pressure roller 6 and a feed roller 7 becomes of a released state.

IPC: G03B7/08
Filed: 1984-06-25
Abstract: PURPOSE:To reduce the stroke of a moving member and to reduce electric power consumption and the time required for resetting the moving member by inverting the moving member by a focusing detection signal in a focusing region and a object brightness signal in an exposing adjustment region. CONSTITUTION:A driving plate 1 is run further toward the right and a switch S2 for changing over a moving direction is opened by a projection 1c to interrupt the conduction of electricity between a light emitting element 6a and an electromagnet 7e to invert a step motor 3 unless a bisected sensor 8 does not detect a focusing point during the focusing stroke. On the other hand, the signal is inputted to a control circuit when the sensor 8 detects the focusing and outputs the focusing signal. Said circuit inverts the output pulses and interrupts at the same time the conduction of electricity to the element 6a and the electromagnet 7e to run the plate 1 in the opposite direction from the midway of the stroke via a motor 3, thereby moving said plate to the exposing stroke region. The control circuit begins to output in succession the pulses of the number corresponding to the object brightness which is preliminarily detected, thereby moving leftward the plate 1 and turning a sector lever 4 in a counterclockwise direction by a cam face if. The opening operation of the sector is executed by the other end thereof.

Title: Manufacture of rapidly solidified metal powder
Inventor: ISAKI HIROSHI
IPC: B22F9/10
Filed: 1990-05-21
Abstract: PURPOSE:To manufacture fine powder without lowering the productivity by adjusting peripheral velocity of cooling liquid layer and injection nozzle diameter. CONSTITUTION:The cooling liquid layer is formed on inner peripheral surface of a cooling drum with action of centrifugal force, and molten metal is injected to this cooling liquid layer to manufacture rapidly solidified metal powder cut into fine particles. At this time, as raising the peripheral velocity of cooling liquid layer, the peripheral velocity of cooling liquid surface is raised and energy cutting the molten metal stream into fine particles with the liquid surface becomes larger. Therefore, even if the molten metal injection nozzle diameter becomes larger and the molten metal stream injected per unit time is a larger quantity, the particles can be made to fine. Further, the productivity can be improved without clogging the nozzle.

Based on the results of the operations, the degree of the opening of a fuel metering valve 5 is adjusted to increase  or decrease the quantity of the fuel to be supplied. Accordingly, the temperature of the surface S  of the refractory substance 1 inside the incinerator can be found accurately from a formula expressing the relation of the distance l between the temperature measuring terminals B and C with  the thermal conductivity of the substance 1, whereby the rise in the surface temperature of the  substance 1 is prevented and thus the life of the substance is prolonged. Moreover, the breakage  of the measuring terminals and the like can be prevented, since it becomes unnecessary to insert  the measuring terminals into the incinerator.
