Patent JP-H11143145-A (JP)
Title: Image forming device
Inventor: AKAIKE AKITOSHI
IPC: G03G15/02
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To efficiently prevent a toner from being adhered to a transfer roller. SOLUTION: Since a prescribed-polarity DC voltage is continuously impressed on a developing roller just before a printing action is finished just after it is started (time t2 -t11 ), the potential of the developing roller is maintained to the prescribed potential of the prescribed polarity and a potential difference between an electrified photoreceptor drum and the developing roller is made small and a toner adhered on the surface of the developing roller is prevented from being flied toward the photoreceptor drum. In accompany with this, a transfer roller is prevented from being soiled by the toner adhered on the photoreceptor drum and recording paper carried to a transfer position is prevented from being soiled by the toner.  Further, the both of the normally electrifying toner and the reverse-polarity toner are eliminated by impressing a DC bias whose the polarity is identical to that of the normally electrifying toner on the transfer roller at the time t7 to t8 after transfer processing is finished and impressing a reverse-polarity DC bias on the transfer roller at the time t8 to t9 . Thus, since the transfer roller is cleaned by avoiding the cleaning at a time before the transfer processing is started but by executing it after the transfer processing is finished, the time until the transfer processing is started is shortened.

Title: Cutoff valve
Inventor: TANAHASHI TAKASHI
IPC: F16K31/06
Filed: 1991-11-19
Abstract: PURPOSE:To simply and securely carry out the open/close operation of a cutoff valve with a small power by contriving such a means as to arrange a main spring for energizing a main valve toward the main valve seat side between a driving part and the main valve, and also to arrange an auxiliary spring for energizing an auxiliary valve toward the auxiliary valve seat side between the main valve and a spring receiver. CONSTITUTION:When a coil 1 is energized, the sum of respective exciting forces of the coil 1 and an attraction piece 2 becomes larger than the energizing force of an auxiliary spring 17 by which an auxiliary valve 9 is pulled down, and a plunger 3 is lifted up and is attracted to the attraction piece 2. Thus, the auxiliary valve 9 is separated from an auxiliary valve seat 12b, and an auxiliary passage 14 is opened. When gas flows into the auxiliary passage 14, the energizing force of a main spring 16 by which a main valve 12 has been pressedly brought into contact with a main valve seat 13 is reduced, so that the main valve 12 is separated from the main valve seat 13 to open a main passage S. When gas flows into the main passage S and the main valve 12 is depressed in the valve-closing direction due to the flow of gas and vibration, the energizing force of the main spring 16 decreases, while that of the auxiliary spring 17 increases, and the main valve 12 is maintained in a valve-opening position.

Filed: 1990-11-13
Abstract: PURPOSE:To miniaturize the title apparatus by holding the forward overvoltage detector and backward overvoltage detector of a thyristor circuit subjected to anti-parallel connection in common. CONSTITUTION:At first, when voltage higher than the break-over voltage of the avalanche diode 361 of an overvoltage detector 171 is applied in the forward direction of a thyristor, the diode 361 is broken down and a break-over current flows to a resistor 371 through the bypass circuit of a backward overvoltage detector 5n1. At this time, a condenser 26p1 is charged from the condenser 331 of a snubber circuit. The discharge current from the condenser 26p1 flows to a resistor 28p1 along with the break-over current flowing out of the resistor 371 and, when voltage drop becomes the break-over voltage of a diac 31pc or more, the diac 31p1 becomes a continuity state and a current is supplied to a light emitting element 29p1. The light emitted from the element 29p1 is transmitted to a gate pulse generator as a light signal. A forward overvoltage signal transmitter 5p1 is constituted in the same way as the backward overvoltage detector 5n1 to be connected to terminals E, F and a terminal B is connected to the cathode part of a thyristor 2p1.
