Abstract: PROBLEM TO BE SOLVED: To provide a method for performing efficiently dry classification of a powder of a highly electrostatically charged substance with a vol. specific resistivity measured by a charging method of at least 1011 Ωcm. SOLUTION: An agitating type cylindrical sieving machine is used as a classifier and a raw material powder fed from a raw material feeding hole 1 is carried to one end of a cylindrical screen 3 and is scattered on the inside face of the screen 3 by means of a blade 4 rotating at high speed. As the blade has a twisted angle, the raw material powder is moved in the left side direction of the figure on the inside face of the screen 3. In this case, the raw material powder is pushed on the inside face of the screen 3 by action of the blade 4 rotating at high speed, and very fine vibration is generated on the face of the screen 3 corresponding to the front and the back of this pushed blade 4.  While this vibration prevents the screen 3 from being clogged, it makes powder particles with a smaller size than the opening of the screen 3 pass through to the outside and the particles are discharged from an outlet 5 for the fine particles.

Title: Copying machine system
Inventor: MIYAZAWA HIDEYUKI
IPC: H04N1/00
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce the probability that a normal operation becomes inactive even if a failure is generated in a control signal by constituting a power interruption circuit to shift a mode to a power saving mode to be set to an OFF when a control signal is not detected. SOLUTION: In the constitution of a Vcc interruption circuit 125, a relay 401 is used as an on/off means. In this case, as the relay 401, a normal close type relay is used. By using the normal close type relay 401, a closing is performed when the control terminal of the relay 401 is at an H level or in an open state and the interruption circuit is turned off. Namely, main power is supplied and a mode becomes a normal operation mode. Because the state becomes an open state because current flows in the coil of the relay 401 when the terminal of the relay 401 becomes an L level from this state, the interruption circuit is turned on. Namely, the main power supply is stopped and the mode becomes a power saving mode. Thus, the mode is made into a normal operation mode in a normal state.
