Filed: 1988-04-26
Abstract: PURPOSE:To simplify the internal structure of a sorter and lower its cost and make its noise lower by providing a movement means whose purpose is to move a sheet retaining means toward a desired bin. CONSTITUTION:When a sheet is discharged form a copying machine, the sheet is sent out via a sheet guide 7, and when a paper sensor S1 detects its tip, a transport motor M1 is started in response to this inspection signal. As a result, rollers 8R, 9R also start rotation, and the sheet is sent into an inclination unit as it is seized by the roller 8R. Next, when the 2nd paper sensor S2 inspects the tip of the sheet, the transport motor M1 is stopped in response to this inspection signal and at the same time, an elevator motor M2 is driven and an upward movement is done toward a predetermined bin indicated in a program. When this inclination unit 4 reaches a discharge position in opposition to the predetermined bin in accordance with the input of a predetermined step, the ascent of the inclination unit 4 is stopped, and the transport motor M1 is started again and the sheet is sent out to the predetermined bin.

Title: Image forming method and intermediate transfer body used therein
Inventor: NISHISE HIDEYA
IPC: G03G15/01
Filed: 1988-04-25
Abstract: PURPOSE:To achieve multiple transfer free of image disorder by employing an intermediate transfer body forming dielectric layers on a conductive base material, electrostatically charging the dielectric layers and bringing them into contact with a photosensitive body. CONSTITUTION:An intermediate transfer belt 10 is composed by laminating the dielectric layers on the surface of the conductive base material. For the conductive base material, urethane with an inherent volume resistivity <=10<5>OMEGAcm is preferable, and for the dielectric layer, polytetrafluoroethylene with a dielectric constant of 2-4 and an inherent volume resistivity of 10<16>-10<17>OMEGAcm is preferable. In synchronization with a photosensitive drum 6, the belt 10 is driven at speed the same as the drum 6, and is electrostatically charged from the surface of the dielectric layer when it passes by an electrostatic charger 11. As a result, when the electrostatically charged part of the belt 10 comes to a primary transfer position, an image of positive toner is transferred onto the belt 10. Thus, every transfer can be surely performed without its pretransfer part adversely affected by image disorder or the occurrence of ozone.

Abstract: PROBLEM TO BE SOLVED: To easily discriminate a peak for indicating the interface of a semiconductor thin film such as an epitaxial layer by correcting the position of a zero point so that the zero point of a reflection factor crosses the wave of the lowest frequency component of a reflection spectrum that is obtained by performing the Fourier transform of detection data and is located in a straight line in parallel with an abscissa. SOLUTION: Luminous flux entering a Michelson interferometer 8 through an aspherical mirror 7 after being emitted from a light source 6 is divided by a beam splitter 9, is reflected by a fixed mirror 10 and a traveling mirror 11, and then is synthesized for interference. Interference light with a different wavenumber is applied to a sample 13 by a mirror 12, the reflection light is detected by a detector 14, and spatial interference intensity waveform can be obtained. The obtained spatial interference intensity waveform is subjected to Fourier transform to obtain a reflection spectrum, and at the same time the zero-point position of the ordinate (reflection factor) of the reflection spectrum is corrected by a zero-point correction means.  Further, by performing inverse Fourier transform using the inverse Fourier transform means, a spatial interference intensity waveform where noise has been eliminated can be obtained.

IPC: H01G11/40
Filed: 1987-04-27
Abstract: PURPOSE:To obtain a small-sized and light-weight electric double-layer capacitor wherein contact failure and conduction failure are avoided, and operation characteristics are stabilized, by a method wherein the metal case of a capacitor main body can be surely brought into contact with the outer peripheral part of a connection cup by inclining said peripheral part. CONSTITUTION:The outer peripheral part of a connection cup 10 is obliquely inclined in the manner in which the aperture side is made wider than the bottom part. The diameter of the bottom part is smaller than that of the metal case 5 of a capacitor main body 1. When one capacitor main body 1 is arranged in the connection cup 10, the metal case 5 of the capacitor main body 1 comes into contact with the outer peripheral part of the connection cup 10. According to this constitution, the metal case 5 of the capacitor main body 1 can be surely brought into contact with the outer peripheral part of the connection cup 10, even if irregularities of dimension accuracy between the connection cup 10 and the capacitor main body 1 exist. Thus the sure welding is enabled, thereby the connection strength and the reliability can be improved.
