Title: Shearing machine for travelling material
Inventor: OOTAKE YUKIO
IPC: B23D36/00
Filed: 1977-11-02
Abstract: PURPOSE: To obtain reliable shearing by rotating a cutter-drum at high speed during the pause to increase its peripery speed, which is then held for rotating a frame during shearing.  
     CONSTITUTION: During shearing process, a brake 20 is taken off so that a frame 1 can rotate with a shaft 2; the drive force given from a shaft 5 is transmitted to a bevel gear 7 through bevel gears 8, 9, 10; then the frame 1 together with the shaft 2 rotates until the axis of cutter drums 18, 19 conform to a vertical line, and the workpiece W is sheared between the two drums 18, 19. In this state, the shaft 5 does not transmit the torque to the drums 18, 19. However, during the suspension period, sufficiently large inertia of rotation or kinetic energies are imparted to these drums 18, 19, so that the drums have kinetic energy sufficiently large for the shearing of the workpiece W.

Title: Toner cartridge
Inventor: NAKAHARA TOMOTOSHI
IPC: G03G15/08
Filed: 1987-05-27
Abstract: PURPOSE:To prevent splashing of a toner and to simplify an operation for exchanging a toner cartridge by fixing one end of a sealing member to a taking-up means mounted freely rotatably in a container and connecting a driving part positioned on the outside of the container to this taking-up means. CONSTITUTION:The taking-up means 15 provided at an axial center begins to revolve and the toner cartridge 3 starts revolving in the same direction simultaneously therewith when the driving for a toner replenishment is transmitted from a main driving gear 17 to a driving gear 16. The projecting part of the cartridge 3 comes into contact with a detaining part 6 formed to a hopper 4 of a developing device 2 to prevent the cartridge 3 from rotating until the cartridge stops. From this time on, only the means 15 keeps rotating and a sheet 18 fixed thereto is gradually taken up from one end A side thereof and, therefore the B side of the sheet 18 sealing an aperture 14 is stripped away. The toner 7 is, therefore, dropped by gravity from the aperture 14 of the cartridge 3 directed in a perpendicular direction toward a toner supplying port 21 side of the hopper 4. The splashing of the toner 7 is thereby prevented.

Filed: 1978-10-27
Abstract: PURPOSE: To simplify the temperature detector circuit and reduce the cost of the circuit by connecting a frequency counter to the output of a circuit for varying the output frequency by the temperature change.  
     CONSTITUTION: An oscillator 21 is constructed by an element having large temperature versus frequency variation amount such as, for example, a crystal vibrator 1. The output from the oscillator 21 and the output from a local oscillator 3 stable against temperature are applied to a mixer 4, which thereupon produces differential frequency output. When the vibrator 1 is installed in a measuring atmosphere, the oscillating frequency of an oscillator 21 is altered in response to the temperature of the atmosphere to be measured.
