Abstract: PURPOSE:To prevent a carrier from sticking to a no-image part and toner from sticking to an image ground part by switching a developing roll bias voltage for the no-image part between images on a photosensitive body so that the voltage is lower than that for image parts on the photosensitive body. CONSTITUTION:The developing roll bias circuit 13 consisting of a boosting and rectifying circuit 10, oscillation control circuit 11, and reference signal circuit 12 is provided so as to prevent a carrier from sticking to the no-image part. The bias voltage V of a developing roll 7 is switched between the image part and no- image part. Namely, the bias voltage V is so controlled that V=VB>VD+VL when the image part faces the developing roll and VB>V>VD when the no- image part faces the developing roll. In this case, VL is the potential of the image background part and VB is the potential for density. Thus, the developing roll bias voltage is controlled to prevent completely the toner from sticking to the image background part and the carrier from sticking to the no-image part between images.

Title: Noise elimination circuit
Inventor: SUWA YUJI
IPC: H03K5/01
Filed: 1991-05-21
Abstract: PURPOSE:To prevent the malfunction of a passive element by providing a delay element receiving an output of a drive element and an AND circuit receiving an output of the delay element and an output of the drive element between the drive element and the passive element. CONSTITUTION:A noise elimination circuit 5 is provided between a drive element 1 such as a driver and a passive element 2 such as a flip-flop. The noise elimination circuit 5 is made up of a delay element 3 receiving a signal (d) being an output of the drive element 1 and outputting a signal (e) and an AND circuit 4 receiving the signals d, e and outputting a signal (f). When the signal (d) outputted by the drive element 1 is a clock signal whose period is constant, the signal (f) outputted from the AND circuit 4 is a pulse signal rising synchronously with the leading of the signal (e) and falling down synchronously with the trailing of the signal (d). Thus, when noise is produced in the signal (d) outputted from the drive element 1, the noise is eliminated before the noise is inputted to the passive element 2.

Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To quickly detect a gas leakage to take a measure to the leakage by providing a control part for determining the gas leakage when a pressure drop rate is larger than a predetermined pressure drop rate threshold. SOLUTION: During the operation of an engine, a first cutoff valve 50 and a second cutoff valve 65 are opened, and according to a command of an injector driver 35, an injector 15 is opened and closed repeatedly. When the first cutoff valve 50 and the second cutoff valve 65 are closed, compressive natural gas is confined in a high pressure pipe 13 and a low pressure pipe 14. When no gas leakage is caused in he pipe, the pressure of the compressive natural gas is substantially constant and little drops. If gas leakage is caused, the pressure drops gradually or suddenly. Accordingly, leakage between the first cutoff valve 50 and the second cutoff valve 65 can be monitored by a first pressure sensor 31 at a control part, and a leakage between the second cutoff valve 65 and an injector 15 can be monitored by a second pressure sensor 33.

IPC: H01F30/00
Filed: 1984-06-07
Abstract: PURPOSE:To interrupt noise in both high frequency normal and common modes for a wider frequency band and also interrupt the noise which enters from any of the input end or output end and passes to the other end in both directions by additionally utilizing the core which shows less reduction of effective permeability at a high frequency or magnetic material such as magnetic sheet. CONSTITUTION:Two kinds of cores (7, 7' and 8, 8') consisting of a magnetic material which shows less deterioration of effective permeability at a high frequency are combined a closed magnetic path core (first core 5) passing through the primary and secondary windings (3, 3') having large effective permeability at a low frequency in accordance with the object input noise frequency. This transformer sufficiently interrupts the noise which enters from any side of input and output devices. Moreover, since the magnetic paths of windings for interrupting common mode noise and interrupting high frequency normal mode noise are separated (like 8 and 7, 8' and 7'), magnetic interference between windings can be prevented and moreover influence of radiated electromagnetic field generated from the winding can be prevented by covering the external circumference of opposed surface of each core with the electrostatic shield plate.
