Abstract: <P>PROBLEM TO BE SOLVED: To provide a highly efficient and low noise electric blower.  <P>SOLUTION: This electric blower has an impeller 11 fixed to one end of an armature (unillustrated), a casing (unillustrated) for covering the impeller 11, and a tight cap 16 composed of a material such as resin, arranged in the center of the casing and making a suction port airtight by contacting with the suction port 11a of the impeller 11. A cylindrical tight member 90 forming a film composed of resin and abutting on the suction port 11a in a cylindrical shape, is alternately arranged in a plurality at a substantially equal interval in the circumferential direction in a tip part of the tight cap 16. Since an interval between the mutual adjacent cylindrical tight members 90 is set to the thickness or less on the tip of the suction port 11a, frictional resistance by contact between the suction port 11a of the impeller 11 and the cylindrical film arranged in the tight cap 16, can be minimized, so that while securing tightness, a loss by friction can be minimized, and a friction sound can also be simultaneously reduced.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: G03G15/00
Filed: 2008-04-08
Abstract: <P>PROBLEM TO BE SOLVED: To surely detect that an amount of toner remaining in an image forming apparatus is small.  <P>SOLUTION: When image data is input to the image forming apparatus 1 in order to perform a printing operation (S11), a control section divides the image data into three image areas, and calculates the black proportion of the image of each area (S12). When the highest back proportion of the image of the image area is stored in a memory (S13), and printing is started (S14), the control section causes an optical sensor to read and detect a toner image formed on an area of the surface of the photoreceptor drum (S15) and calculates the black proportion of the toner image in the area (S16). The control section then compares the black proportion of the data with the black proportion of the toner image (S17), and if the black proportion ratio is equal to or below a threshold (S17: NO), the control unit determines that an amount of remaining toner is equal to or smaller than a predetermined amount and temporarily stops printing. Accordingly, a conveying operation and an image forming operation for the recording paper being printed at the time and the subsequent recording paper are stopped.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To lessen stress applied to an electrooptic element by applying inverse bias in turning out the electrooptic element.  <P>SOLUTION: The supply of power supply potential DS to a power supply line is stopped during a part of nonradiative period of an organic EL element to put the power supply line in the floating state. Thus, an electrode on the power supply line side of a driving transistor, that is, a drain electrode is also put in the floating state. At this time, since inverse bias is not applied to the organic EL element, the inverse bias period can be remarkably reduced as compared with the case where the supply of power supply potential DS is not stopped. As a result, the stress applied to the organic EL element due to the application of the inverse bias is reduced, so that it is possible to restrain a change in characteristic of the organic EL element or dark dot defect due to the stress.  <P>COPYRIGHT: (C)2010,JPO&INPIT
