Title: Sheet conveying device in image forming apparatus
Inventor: SHIMOMURA YOSHINOBU
IPC: B65H5/22
Filed: 1985-09-24
Abstract: PURPOSE:To prevent variations in sheet conveying speed, generated in a fixing section from being transmitted to an image transfer section, by providing an absorbing means for absorbing a sheet to make the latter into contact with a belt conveying device with a predetermined force. CONSTITUTION:A sheet S onto which a toner image is transferred from an exposure drum 12 by means of a transfer charger 16, is conveyed at a uniform speed by means of a sheet conveying device B with the unfixed toner image being held on its outer surface. Further, when the leading end of the sheet S is pressed onto a pair of fixing rollers 25, the sheet S is exerted with a shock and is formed in a loop shape. Further, such a shock and a loop shape is liable to be propagated to the trailing end section of the sheet S. However, since an air suction duct 35 laid in the lower section of a conveying belt 22 applies suction force produced when a suction fan is operated, upon the sheet S from an air suction port 36, the propagation of the above-mentioned shock and the loop shape are isolated. Thereby, the trailing end section of the sheet S still remaining in the transfer section A is transferred thereon with an image without being affected by the shock and the loop shape, and is then conveyed to a fixing section 23.

Abstract: PROBLEM TO BE SOLVED: To provide a device having small variations in propagation characteristics with good reproducibility by controlling the surface condition of a water for forming electrodes for transmitting and receiving surface acoustic waves by the power value of the profile data measured by a surface roughness meter. SOLUTION: The wafer of lithium tantalate or lithium niobate is used for a piezoelectric single crystal. Power spectra are used for the quantitative determination of the surface condition. The power value and the propagation characteristic of the surface acoustic waves and more particularly the surface acoustic wave velocity correlate. The power value p(k) is determined by the Fourier transformation of the profile data obtainable by a stylus type roughness meter, an optical roughness meter, etc., and by equation (1). In the equation (1), πis a circle ratio; (d) is a sampling interval; N is a sampling number; F(k) is the Fourier transform value of the profile data. The relation between the polishing conditions of the wafer surface and the power spectra is previously so investigated that the power value attains <=10 k<-1> nm<3> at the space frequency k of >=0.1 μm<-1> .  The wafer is then produced by polishing.

Title: Magnetic separation method and apparatus therefor
Inventor: YANO JIYUNICHI
IPC: B03C1/034
Filed: 1981-12-30
Abstract: PURPOSE:To improve the trapping property of magnetic particles with varying intensity of magnetic fields in various areas without increase electric energy by dividing a filter element areas between pole pieces with a dispersing plate with a shunt body provided in one area. CONSTITUTION:The area of a filter element formed between pole pieces 16 and 17 is divided into regions 11 and 12 with a division plate 24 while a shunt body 26 is arranged in the region 11. When an electromagnetic coil 22 is energized the line of magnetic force coming through the pole piece 16 reaches the dispersing plate 24 mostly passing through the shunt body 26 while a part thereof passes through the region 11. So, the magnetic force is weak in the region 11. The line of magnetic force reaching the division plate 24 reaches the pole piece 17 passing through the region 12 from the division plate 24. So, the magnetic force is strong in the region 12. In this way magnetic particles having a large particle size or a large magnetization rate in a liquid to be treated flowing from a passage are trapped by the region 12 and those having small particle size are trapped in the region 12.

Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To stably detect the density of a picture with accuracy by providing a luminous flux regulating member at the light emitting opening of a light emitting element. SOLUTION: A picture 9 for detection which is an object to be measured on an image carrier 8 is irradiated with light emitted from a light emitting element (LED) 1 through an aperture (luminous flux regulating section) 5 and the light corresponding to the density of the picture 9 is made incident on a light receiving element (photodiode) 3 which measures the density of the picture 9. Since part of the light irregularly reflected by the picture 9 returns to a light receiving element 2 for monitoring although most of the irregularly reflected light enters the element 3, an aperture which intercepts the part of the irregularly reflected light is installed at the LED opening 12 of a sensor holder 4 for intercepting the part of the irregularly reflected light.  Therefore, the light returning to the element 2 is intercepted and the quantity of the light emitted form the LED 1 can be monitored accurately.
