Title: Control method of developer
Inventor: MOMOTAKE NOBUO
IPC: G03G15/09
Filed: 1984-03-29
Abstract: PURPOSE:To form a stable developer layer without clogging of a trimmer by disposing repulsive magnetic poles of the same pole having prescribed magnetic force on the upstream side and downstream side facing a blade for controlling a one-component magnetic developer layer. CONSTITUTION:The thickness of a developer layer formed on an image carrying body 5 by a one-component developer 3 is controlled by a control blade 6. Repulsive poles N1, N2 of the same pole are disposed to a magnet roll 4 facing the blade 6 and the intensity of the magnetic pole N2 on the outlet side in the control part is made larger than the magnetic pole N1 on the inlet side, by which the accumulation of the developer 3 to be trimmed and the uneven conveyance of the developer in the stage of trimming are prevented. The developer chains which are held erected in the control part by the repulsion of the same pole are cut by the blade 6, by which the amt. of the developer to be stuck to the carrier 5 is decreased. The stable developer layer is thus formed on the image carrying body without clogging of the trimmer.

Abstract: PURPOSE:To prevent generation of a void part in a boundary of a picture and a character, by constituting so that a shape representing dot pattern contains not only a figure dot showing a shape but also a background dot for constituting a part of a picture. CONSTITUTION:When reproducing a picture having a character, etc. fitted in a part of the picture, a picture data and a figure data are read from an original picture and an original of a character, etc., respectively. That is to say, as for an original picture 1, its density is measured at every picture element, and its density level data 10 is recorded in input files 11-13 of every three colors. On the other hand, as for a character original 2, a binary-coded density level data 16 is obtained by executing the color separation photometry by size of a cell of a dot matrix to be used, it is converted to a dot pattern number 17 prepared in advance, and is stored in an input file 18. The picture and the figure data stored in the files 11-13 and 18 are synthesized and stored in data files 19-21. A synthesized data is read out successively, and becomes a control signal for ink jet.

Inventor: KITAMURA NORIYUKI
IPC: H02M7/538
Filed: 1994-03-29
Abstract: PURPOSE:To provide a lighting system of a simple structure with small distor tion. CONSTITUTION:In a steady state, a first and a second switching device SW1, SW2 are alternately turned on and off. When the second switching device SW2 is turned on, a primary winding Tr1 of a leakage transformer Tr is charged with electric charge of a capacitor for smoothing C2. Then, when the second switching device SW2 is turned off, current flows through the route of the primary winding Tr1 of the leakage transformer Tr, a diode D2, a capacitor C3, a diode D1, and the primary winding Tr1 of the leakage transformer Tr. When the first switching device SW1 is turned on, the capacitor for smoothing C2 charges the primary winding Tr1 of the leakage transformer Tr and the current which flows in the primary winding Tr1 becomes the one which improves a power factor. When the first switching device SW1 is turned off, current flows through the route of the primary winding Tr1 of the leakage transformer, the capacitor for smoothing C2, a diode D3, and the primary winding Tr1 of the leakage transformer Tr. By this method, noise decreases and distortion becomes small.

Title: Photoconductive element and method for manufacturing the same
Inventor: YAMAMOTO HIROCHIKA
IPC: H01L31/0248
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To enable manufacture without having to use complex working methods, and to allow faster operation. SOLUTION: An average particle size of a diamond layer 2 among an electrode 3 is smaller than an inter-electrode gap 6. Thus, a grain boundary exists at the inter-electrode gap. When the diamond layer 2 between the gaps 6 is irradiated with an excitation light 5, an electron and positive hole are produced as optical carriers in the diamond layer 2, each of which moving the facing electrodes 3 which are respectively biased. Since the electron and positive hole cause recombination at the grain boundary of diamond, the lifetime of the optical carrier can be made shorter and with faster operation. Since a part facing the electrode 3 is surrounded by the diamond layer 2 and an overcoating diamond layer 4, the electrode 3 can be applied with a large bias, so that high output is obtained.

Abstract: PURPOSE: To enable integration monolithically by connecting the base terminal of a pnp transistor to an electric conductor through the parallel circuit of a high resistance resistor and a first capacitor, and at the same time connecting it to a reference potential (the ground) through a second capacitor. CONSTITUTION: While a normal signal is applied to a conductor L1, the central signal level of the signal is applied to the base terminal of a pnp transistor T1 through a resistor R1, and a fast voltage change on the conductor L1 relative to a capacitance ratio C1/C2 is brought into a suitable voltage change in the base terminal of the transistor T1. When a positive ESD pulse is applied to a contact place, the voltage is divided according to the capacitance C1/C2. At that time, when a voltage which is larger than the threshold voltage of the transistor T1 is lowered through the capacitor C1, the transistor T1 is brought into an electrically conducting state, and also the voltage level on the conductor L1 is limited in such a manner.
