Title: Image formation
Inventor: KUREMATSU KATSUMI
IPC: G03G15/05
Filed: 1983-05-18
Abstract: PURPOSE:To form an electrostatic latent image, transfer and develop only toner at a light-irradiated part to a transfer material by irradiating a thin layer of photoconductive toner on the surface of a bias-impressed cylindrical body with a light image. CONSTITUTION:A developing sleeve 1 is impressed with a DC and AC mixed bias from a power source 15 and coated with a thin layer of photoconductive toner 4a charged electrostatically in minus state by friction. Only polarized toner is transferred from the sleeve 1 to an insulating transfer drum 2 put closely to the sleeve 1 by a corona electrode 11 and developed. The toner image from this drum 2 faces a fixing roller 3a closely and the toner moves to the surface of the fixing roll 3a through the transfer corona electrode 12 and bias 14. The toner image on the roller 3a is transferred to and fixed on paper 10 carried from a resist roller 6 to between fixing rollers 3a and 3b at the same time by the pressure between both rollers to obtain a copy picture.

Title: Ignition timing detecting method
Inventor: AOKI KEIJI
IPC: F02P17/04
Filed: 1983-05-18
Abstract: PURPOSE:To detect accurate ignition timing by converting combustion light detected by means of a flame sensor to voltage, comparing it with reference voltage, while changing this voltage in response to an engine operation state. CONSTITUTION:Voltage signals from a photodiode 11 detected by means of a flame sensor 1 differ in their waveforms depending on engine load. Outputs from a comparator are made the same in their rise time by changing reference voltage Vt. Hereby, detected time delay from actual ignition timing to detection time is not varied by the changes of the engine load, enabling accurate ignition time to be detected whatever engine load states may occur.

Title: Semiconductor integrated circuit
Inventor: SETO YUICHI
IPC: H03F3/45
Filed: 1988-04-12
Abstract: PURPOSE:To obtain a differential amplifier circuit with a small offset voltage by connecting an FET with the pinch-off characteristic similar to that of a signal input FET as a load of the FET receiving said signal. CONSTITUTION:Suppose that a pinch-off current Idss1 of an FET 1 is larger than a pinch-off current Idss2 of an FET 2, a gate-source voltage Vgs1 of the FET 1 has a relation of Vgs1>Vgs2 with respect to said voltage Vgs2 of the FET 2 and an offset voltage is generated. Since the pinch-off current of an FET 3 is larger than the pinch-off current of an FET 4, a current flowing to an npn transistor(TR) 5 is increased. Then a current flowing to an npn TR 7 is decreased and the current of the FETs 1, 2 is varied to attain Vgs1=Vgs2. Since the current flowing to the FETs 3, 4 is distributed from a constant current circuit 9, the offset voltage is reduced more than the compensation effect by the FETs 1, 3 and the FETs 2, 4.

Title: Minute tube filled with abrasive grains
Inventor: KAMITSUMA SATOSHI
IPC: A46B3/22
Filed: 1990-04-03
Abstract: PURPOSE:To decrease the possibility that abrasive grains are drifted away against a shock from the outside by filling the inside of a minute tube whose material is SUS, copper, an alloy, etc., with grinding/polishing abrasive grains of a diamond, boron, carborundum, etc., and also, constituting it by performing plastic working by a roll, a die, etc. CONSTITUTION:The inside of a metallic tube 1 whose material is SUS, copper, an alloy, etc., is filled with abrasive grains 2 of a diamond, boron, carborundum, etc. The outside diameter of the metallic tube 1 swells out in the part of the abrasive grains 2. It is because the tube is tightened by a roll, a die, etc., from the outside after filling it with the abrasive grains, therefore, a difference is generated in the outside diameter in the part in which the abrasive grains 2 exist and the part in which they do no exist. In the case of using this filled abrasive grains 2 as a grinding brush together with the tube, since the tubular body grasps strongly the abrasive grains in this constricted part so that the abrasive grains are not drifted away, the abrasive grains 2 are no drifted away. Also, since a shock applied to the abrasive grains 2 of a diamond, etc., is softened by the metallic tube 1, it dose not occur that the cutting blade is broken off by damage.
