Title: Cleaning method of metallic strip after cold rolling and device therefor
Inventor: SEKINE TATSUO
IPC: C23G3/02
Filed: 1994-12-27
Abstract: PURPOSE: To omit equipment, such as alkali immersion tanks, reduce the quality defects and improve the yield by first degreasing the surfaces of a metallic strip by a contactless type electrolytic washing device, then spraying high- pressure water of a specific pressure thereto. CONSTITUTION: A rough washing tank 1 is the contactless type electrolytic washing device of a primary cleaning section where the metallic strip 3 passing the tank is degreased with an alkaline electrolytic washing liquid. In succession, a finish washing tank 2 is a high-pressure water spray washing device of a secondary cleaning section where the high-pressure water of a pressure of >=10kg/cm<2> is sprayed to both surfaces of the metallic strip subjected to the rough washing and the oil, iron powder, etc., remaining after the primary cleaning are completely removed. The metallic strip is thereafter subjected to drying with a drier, etc., and is progressed to the ensuing stages. The alkali immersion device, brushes, earth rolls and rinsing tanks used heretofore are omitted.

Title: Improper injection preventing method for diesel engine fuel injection valve
Inventor: NAGASE KAZUHIKO
IPC: F02D41/22
Filed: 1989-12-15
Abstract: PURPOSE:To prevent improper injection due to competition of a residual injection pressure with a reflected wave by constituting an injection valve preventing the improper injection by forming a throttle passage in the vicinity of a high pressure pipe inlet only when the reflected wave rereflects in the vicinity of the high pressure pipe inlet. CONSTITUTION:In order to absorb or damp with no reflection in the terminal end of a pipe line a pressure wave, propagated in the inside of the pipe line with a fixed section such as a high pressure pipe 3, the pipe line is only required to be opened in its terminal end to a low pressure opening part, for instance, to the atmosphere through a suitable throttle narrower than said pipe line. And a diameter of the throttle can be obtained in its suitable value by calculation or experiment when fluid is determined in its pressure, density and viscosity or the like. Accordingly, in case of the problem thus generated, when a reflected wave, generated in an end part of the high pressure pipe 3, rereflects in an inlet of the pipe 3, the reflected wave is damped by opening the inlet to the outside through the throttle set to the suitable value, thus an effective method can be obtained preventing improper injection.

Title: Heater and image forming device equipped with the same
Inventor: WATANABE OSAMU
IPC: G03G15/20
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent charging-up which causes the soil of a pressure member by installing an electrostatic charging member in contact with the pressure member arranged opposite to a heat generating member and impressing a voltage on the electrostatic charging member. SOLUTION: The pressure roller 28 as a pressure member is brought into press contact with the bottom surface of a heater 20 as a heat generating member with a fixation film 25 interposed in an opposed state by an energizing means. And a scraper 51 as the electrostatic charging member is installed under the pressure roller 28 so as to be laid in a forward direction with respect to the rotating direction of the pressure roller 28. By impressing the voltage on the scraper 51 which is brought into contact with the pressure roller 28, the occurrence of spotted stain is prevented.  That is, in the case where the toner is negative, almost the toner on a transfer material is reversed to a positive polarity by a positive transfer bias, then, it is easy for the toner to stick on the surface of the pressure roller 28 whose surface layer is formed of material which is easily electrostatically charged to the negative polarity, then, the negative potential of the pressure roller 28 is reduced by impressing the positive voltage.

Title: Level converting circuit
Inventor: MIYAZAKI TOMOHIRO
IPC: H03K19/018
Filed: 1989-12-15
Abstract: PURPOSE:To obtain a pulse output which has an amplitude twice as large as a source voltage by connecting a DC power source to the power terminal of a level converting means through a reverse current preventive diode, and connecting a capacitor between the output of an inverter and the power terminal. CONSTITUTION:The DC power source 1 is connected to the power terminal 10 of the level converting means 8 through the reverse-current preventive diode 5 and the capacitor 6 which has sufficient capacity for charging the voltage of the DC power source 1 at the timing of the transmission of a common potential from the output of the inverter 2 with the potential at an output terminal 3 is connected between the output of the inverter 2 and source terminal 10. When a signal of level which is large in absolute value arrives at the input terminal 3, a signal of level which is small in absolute value is outputted to the output terminal. At this time, the capacitor 6 is charged by the DC power source 1 and when a signal of level which is small in absolute value arrives at the input terminal 3, a voltage 2V1 which is the sum of the voltage V1 of the DC power source and the voltage V1 of the capacitor 6 is outputted. Consequently, the pulse output which has the amplitude twice as large as the source voltage is obtained by using the single DC power source.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a crack in a film during heat welding by sealing jaws and restrict degradation in the item preservability of a packaging bag. SOLUTION: By providing block members 28 and 29 in the vicinity of the opposite contact faces 14a and 15a of seal jaws 14 and 15, respectively, a gap of a specific width is made for preventing both the block members 28 and 29 from contacting each other even when the seal jaws 14 and 15 oppositely contact each other, and a film f is bent along the upper edges of the block members 28 and 29 when the seal jaws 14 and 15 oppositely contact each other. Also the film f is provided so as not to contact the seal jaws 14 and 15 except the opposite contact faces 14a and 15a.  Thus, the depth X of a recess Y between the opposite contact faces 14a and 15a is increased, the bent portions A and B of the film f are separated from the opposite contact faces 14a and 15a, which makes it difficult for the heat of the opposite contact faces 14a and 15a to be transferred to the bent portions A and B and also the opening angle θof the film f is made small.
