Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce the peak power consumption of an image forming device by allowing a fixing means to restrain the power consumption of a heater when an original scanning body is on its return stroke. SOLUTION: A printer part 3 performs image exposure on a photoreceptor drum 7 based on an image signal transmitted from a reader controller 6, so that an electrostatic latent image is formed. The electrostatic latent image is made visualizable with toner by a developing unit 8, and then primarily transferred to an intermediate transfer drum 9. The toner image is transferred to recording material by a secondary transfer part 10, and the recording material where the toner image is put is carried to a fixing device 4 from a transfer belt 11, and the toner image is fixed on the recording material by the action of heat and pressuring force. At such a time, the controller 6 transmits an interruption signal to the printer part 3 in synchronization with back scanning operation performed to return to an initial position in original scanning by a light source 2.  The printer part 3 changes the temperature control method for the fixing device 4 based on the transmitted interruption signal.

Abstract: PROBLEM TO BE SOLVED: To keep image quality constant in spite of the deterioration of developer even when the kind of the developer is changed by applying a developing bias based on the output information of a developing bias parameter setting means to a developer carrier by developing bias power source. SOLUTION: A counter outputs the number of prints and the summed-up operation time of a device to transmit them to an overall control part. The overall control part calculates a bias parameter based on data from a developer information part and the output data of the counter to transmit the bias parameter to bias supply. In this bias supply, the peak-to-peak voltage value of a bias is periodically set on the basis of the data of the bias parameter, a waveform is formed and amplifying to a high voltage is attained, to apply the bias to the developing sleeve of a developing device with fixed timing. Therefore, a proper bias is developed/applied from an estimate of the deterioration pattern and present deteriorated state of the developer, so that the quality of the image such as dot uniformity can be always kept in a constant state.

IPC: C22B7/04
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To produce aluminum sulfate while reducing the water content of amorphous aluminum hydroxide sludge without changing its properties. SOLUTION: In this production, amorphous aluminum hydroxide is finely pulverized, and thereafter, the pulverized aluminum hydroxide is dispersed into a hot air stream to instantaneously evaporate water in the pulverized aluminum hydroxide.

Abstract: PURPOSE:To use a catalyst, consisting of a thin film of Pd and P or B readily preparable by a vacuum vapor deposition method, readily separable from products and exhibiting high selectivity in partially hydrogenating a cyclodiene compound to provide a cycloolefin. CONSTITUTION:A cyclodiene compound (e.g. dicyclopentadiene) is partially hydrogenated in the presence of a thin film consisting of Pd and P or B prepared by a vapor deposition method as a catalyst at -10-+100 deg.C to afford the titled substance.

Title: Driving circuit of switching transistor
Inventor: HORIGAMI KOUICHI
IPC: H03K17/61
Filed: 1982-12-10
Abstract: PURPOSE:To attain the reduction in a storage time and a rising time with less driving power by constituting a titled circuit that a transistor (TR) for back bias is kept conductive by a feedback current when the TR is conducted once. CONSTITUTION:When an input signal from a driving input terminal 2 is eliminated and a trigger pulse biasing forward a TR5 is applied to a trigger signal input terminal 7 at the same time, the TR5 is conductive and a storage charge in a TR1 starts being diffused to a negative power supply terminal 3. A collector current of the TR5 is fed back positively to a base of the TR5 even after the trigger pulse at the terminal 7 is lost and the TR5 maintains the conductive state. Further, when the stored charge of the TR1 is annihilated the TR5 is cut off. In the principles of operations above, since the driving signal of the TR5 is the trigger pulse only and the conductive state is maintained by a feedback current after the TR5 is conductive once, the driving power of the TR5 is less. Moreover, since the conductive period of the TR5 is finished together with the interruption of the TR1, the delay in the rising time of conduction of the TR is reduced.
