IPC: G03G21/10
Filed: 1992-04-16
Abstract: PURPOSE:To obtain a process cartridge and an image forming device where the process cartridge can be accurately positioned in the device main body. CONSTITUTION:In the image forming device which forms an image with the process cartridge 4, composed of a housing 4e covering a photosensitive drum 4a and at least one process means which acts on the photosensitive drum 4a, loaded therein, the process cartridge 4 is positioned by making the frame of the device main body support both ends of the rotary shaft 4a3 of the photosensitive drum 4a and at least one support part 4e2 provided on the housing 4e. Since the process cartridge 4 does not rotate around the rotary shaft 4a3, it is accurately positioned in relation to the device main body to be loaded therein.

Title: Production of hermetic-covered optical fiber
Inventor: FURUGUCHI MAKOTO
IPC: G02B6/44
Filed: 1989-05-15
Abstract: PURPOSE:To obtain optical fiber with sufficient hermetic coating thickness by feeding a raw gas for coating as well as halogen gas into a reaction oven to pass optical fiber. CONSTITUTION:Drawn optical fiber is passed through a reaction oven to coat its surface with a hermetic coating consisting of carbon or carbon compound. In this case, halogen gas such as chlorine is added to a raw gas for coating such as C2H4. The raw gas and chlorine are mutually put to exothermic reaction in the reaction oven, and the heat thus produced will help the thermal decomposition of the raw gas. Thereby, hermetic coating formation will be promoted even if the surface temperature of the optical fiber is somewhat lower. Also, the manufacturing conditions for such optical fiber can be set in a broader way than ever, thus stably obtaining the objective optical fiber.

Abstract: PURPOSE:To decrease the amt. of an inert gas to be used by forming a gas flow path to an electrode to be immersed in slag and discharging the inert gas to increase the slag thickness and to decrease the amt. of the inert gas to be supplied. CONSTITUTION:A molten steel 3 is tapped from a converter into a ladle 1 and the electrode 5 is immersed in the slag 4 on the molten steel 3. The electrode 5 is then energized to form an arc between the electrode 5 and the molten steel 3 and to heat the molten steel 3 by the arc. The inert gas (gaseous Ar) is discharged as a prescribed flow rate from the gas flow path 6 provided to the electrode 5 in the longitudinal direction thereof to fill the circumference of the arc with the inert gas and to prevent the nitrogen pickup of the molten steel 3. A flux is introduced into the molten steel 3 to execute the slag refining of the molten steel 3 with progression of the arc heating treatment and therefore the thickness of the slag 4 increases gradually. The flow rate of the inert gas to be discharged is so adjusted as to be decreased with an increase in the slag 4.

Abstract: PURPOSE: To detect breakage by means of a piezoelectric sensor in order to adjust or shut out the pressure of a cleaning blade applied to the surface of the photoreceptor. CONSTITUTION: The piezoelectric sensor 60 is attached to the cleaning blade 58 or the blade supporting member 62 of an electrostatic copying machine. The sensor 60 generates waveform showing the friction characteristic of the blade 58 and the pressure load of the cleaning blade applied to the surface of the photoreceptor. A detection circuit forms a feedback system between the sensor 60 and a pressure load device 64 and a piezoelectricity signal is transmitted from an amplifier 70 to a comparator 71 and a differential circuit 72. When the comparator 71 predicts the perfect breakage of the blade 58 due to the lowering of detected sensor voltage, the effect is displayed to urge the exchange of the blade. The differentiation circuit detects the sudden rise of the piezoelectricity signal and a pulse oscillator 74 actuates a solenoid 64 so as to decrease the pressure of the blade 58.
