Title: Manufacture of toner for developing electrostatic charge image
Inventor: UETAKE SHIGERU
IPC: G03G9/087
Filed: 1980-02-28
Abstract: PURPOSE:To manufacture a toner with superior fluidity, charging characteristics, etc. in a high yield without requiring the removal of a water soluble emulsion stabilizer contributing to the charging characteristics of the toner by subjecting toner starting materials to suspension polymn. in an aqueous soln. of the stabilizer or sphering a pulverized toner in the soln. CONSTITUTION:Toner spherical particles are obtd. by subjecting toner starting materials to suspension polymn. in the presence of a high-molecular compound as an emulsion stabilizer having structural units represented by formula I or their salt in the structure. In the formula I, each of R1 and R2 is H, 1-20C alkyl or COOH,  R3 is 1-4C alkyl, Cl or CN, X is CO, COO(CH2)n (n is 1-5), OCH2, OCH2CH2 or the group of formula II or III, each of R4 and R5 is H, 1-20C alkyl, benzyl, (substituted) phenyl or (substituted) naphthyl, and the substituent is OH, alkyl or the like. Pulverized toner may be sphered by heating in an aqueous soln. of the stabilizer. Even if the polymn. or sphering is carried out at a high temp., the resulting toner particles are not stuck to each other and made coarse, and the stabilizer contributes to the charging characteristics of the toner to make the removal unnecessary. Thus, the superior toner is obtd. in a high yield.

Title: Horizontal synchronizing signal measuring circuit
Inventor: MORI HISASHI
IPC: H04N5/445
Filed: 1990-01-31
Abstract: PURPOSE:To preclude output variation based upon the position relation between a vertical and a horizontal synchronizing signals by switching the horizontal synchronizing signal and the dummy pulse output of a dummy pulse generating circuit with the output of a register circuit, and using the output as a clock and the vertical synchronizing signal as a reset signal. CONSTITUTION:A horizontal/dummy switching circuit 4 outputs a dummy pulse in a next area A when the output of a register circuit 5 indicates an area A, and then outputs the horizontal synchronizing signal instead by switching. When an area B is indicated, the dummy pulse is not outputted in the next area A and the horizontal synchronizing signal is outputted. A horizontal synchronizing signal measuring circuit 8 uses the vertical synchronizing signal III as the rest signal and uses the output of the horizontal/dummy switching circuit 4 as the clock. Therefore, when the vertical synchronizing signal is inputted optionally for the horizontal synchronizing signal, a closer horizontal synchronizing part is counted as a 1st pulse. Consequently, the difference in display position due to the measurement error of the horizontal synchronizing signal measuring circuit becomes less than 1/2H and vertical vibration becomes inconspicuous, so that a stable display is obtained.

Title: Measuring system of red hot objects
Inventor: NAKAMURA TSUTOMU
IPC: G01J5/10
Filed: 1978-03-01
Abstract: PURPOSE:To measure the surface condition securely, by using the modulated light corresponding to the oscillation output as the radiation light, demodulating the reflected light signal from the image pickup signal due to reflected light from a red hot object and emitting light of red hot object, and writing and reading in synchronism with scanning. CONSTITUTION:A light source 2 generates a modulated light corresponding to the oscillation output of an oscillator 6 by means of a scanner 5 and a driver 3 to radiate the surface of a red hot object. The reflected light of this radiation light from the red hot object 1 and the emitting light of the red hot object 1 are picked up by a detector 4, and this image pickup signal is demodulated by demodulator 7 which is controlled by the oscillator 6. Thus, the demodulator 7 demodulates the reflected light component and stores into a memory 8. Writing and reading of this memory 8 are performed through a read/write device 10 which is controlled by the scanner 5. In this way, in synchronism with the scanning, the time division signal of the reflected light component corresponding to the surface condition may be applied to a display device 9, so that the surface condition of the red hot object may be measured securely regardless of the effects of the emitting light of the red hot object.

Title: Substrate washing method and substrate washing device
Inventor: NAKANO YASUSHI
IPC: H01L21/304
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To drastically decrease the amt. of the static electricity to be generated and to prevent the occurrence of a defect occurring in static electricity, as metallic wiring dissolution, by using the washing water prepd. by dissolving a salt not contg. metal elements or gaseous carbon dioxide at a high concn. into ultrapure water to lower the resistivity thereof. SOLUTION: This washing device senses the flow rate of the ultrapure water flowing into a washing water pipe 110a by a flow meter 111. Ammonium carbonate water which is the salt not contg. the metal elements in a tank 113 is intermittently injected by an injection pump 114 in accordance with the flow rate into a washing water pipe 110a. At this time, if the flow rate of the ultrapure water sensed by the flow meter 111 is large, the intermittent intervals are made shorter by the control of a controller 115 and if the flow rate is small, the intermittent intervals are made longer to a maintain the concn. of the ammonium carbonate which is the washing water constant. The setting of the concn. is executed by inputting desired electroconductivity into the controller 115.  The information from an electroconductivity meter 112 is fed back to the injection pump 114 to maintain the desired electroconductivity of the washing water. For example, a static mixer 117 is disposed between the injection pump 114 and the electroconductivity meter 112 to well mix the ultrapure water and the ammonium carbonate water.

Title: Optical receptive member
Inventor: SAITOU KEISHI
IPC: G03G5/08
Filed: 1984-02-13
Abstract: PURPOSE:To obtain an optical receptive member which can prevent an interference fringe pattern appearing at the time of forming an image and an appearance of a speck at the time of an inversion development, by constituting a titled member so that a photosensitive layer has non-parallel interfaces of one pair or more in a chute range and a lot of non-parallel interfaces are arranged at least in one direction in the surface vertical to the leyer thickness direction. CONSTITUTION:The layer thickness of the second layer 602 of an optical receptive layer of multi-layer constitution having one or more photosensitive layers consisting of an amorphous material containing a silicon atom is varied continuously to d6 from d5, therefore, an interface 603 of the first layer 601 and the second layer 602, and a free surface 604 of the second layer have an inclination to each other, and interference light which has been made incident on a minute part (short range) l generates a minute interference fringe pattern, but a difference in light and darkness of the interference fringe pattern becomes small to the extent that it can be disregarded, compared with the case when a pair of interfaces are in a parallel relation. This fact can be said in the same way even if a layer thickness of the second layer 602 is ununiform (d7not equal to d8) as macro. Also, in case when the optical receptive layer is constituted of a multi-layer, the interference becomes a geometrical effect in each layer, therefore, the interference effect can further by prevented.

Title: Pm data collection device
Inventor: NODA SHUICHI
IPC: H04L69/40
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To reduce a collection integration time of PM data (performance monitoring). SOLUTION: A function block 1 whose function is divided for each transmission layer divides a signal from a transmission line and terminates them and generates PM data and integrates the data for each end point. When a PM integral value at each termination end point is all zero, that is, when no transmission line error is in existence at all the termination points, the function block 1 sets a zero flag. A PM collection integration block 2 confirms the zero flag of the function block 1 that is an object of collection before collecting and integrating the PM data from each function block 1. The PM collection integration block 2 stops the collection and integration of the PM data from the function block to which the zero flag is set.
