Title: Color image forming device
Inventor: KATSUURA YOSHIKO
IPC: G03G15/20
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a color image forming device capable of performing fixation on a transparent sheet at a high speed, obtaining a high resolution, and securing the transparency of a color toner image by making the height of toner on material to be recorded which is pressed before passing through a fixing device and that on the material after passing through the fixing device satisfy a specified condition. SOLUTION: The transparent sheet being the material to be recorded 113 enters the press-contact part 209 of a pressing means from a direction shown by an arrow. By receiving bias electric field and pressing force, a pre-fixation image 205 is compressed to the height of toner h1 and charged. Furthermore, the sheet enters the press-contact part 204 (nip) of a fixing means. After the fixation in a heating roller 201 and a pressure roller 202, the image 205 becomes a post-fixation image 206, and the sheet is ejected from the fixing device. The height of toner at that time is h2. The relation between the height of toner h1 and h2 satisfies the condition h1/h2<=3.4, so that deforming compression amount applied to a toner layer becomes very little so as to obtain a high- resolution OHP image.

Title: High-frequency sputtering method and production of magnetic recording medium
Inventor: MORITA HARUYUKI
IPC: G11B5/85
Filed: 1989-12-21
Abstract: PURPOSE:To obtain a magnetic layer uniform in thickness and magnetic characteristic at the time of simultaneously forming a film by sputtering on both principal planes of a substrate by deviating the sputtering frequency on one side of the substrate from that on the other side by a specified frequency. CONSTITUTION:A target is respectively opposed to the principal planes of a substrate, and a film is simultaneously formed on both principal planes of the substrate by high-frequency sputtering. In this case, when the frequency of the high-frequency sputtering performed on one principal plane of the substrate is estimated at fA MHz and that on the other principal plane at fB MHz, 0.003<=¦fA-fB¦<=0.013, fA=13.56000+ or -0.00678 and fB=13.56000+ or -0.00678 must be fulfilled. When ¦fA-fB¦ is less than the above-mentioned range, the uniformity in the film thickness is affected by the mutual intervention between the electric fields on both sides of the substrate, and the upper limit of ¦fA-fB¦ is obtained from the above-mentioned ranges of fA and fB.

Title: Method and device for processing toner
Inventor: SHIMIZU TAMOTSU
IPC: G03G15/08
Filed: 1988-12-27
Abstract: PURPOSE:To appropriately maintain the charging ability of carrier for a long time and to obtain a distinct image without fogging by mixing an electrostatic charging member which is electrostatically charged to have an opposite polarity to toner by contacting with the toner with the toner and separating only the toner. CONSTITUTION:The toner 2 is mixed with the electrostatic charging member 1, for example, iron powder, which is electrostatically charged to have the opposite polarity to the toner by contacting with the toner 2 and does not contribute to development. Therefore, the toner 2 and the charging member 1 frictionally contacts with each other and they are electrostatically charged to have the opposite polarity each other. At the same time, the fine powder of the toner and the spent component 3 of an electrostatic charging control substance, etc., isolated from toner particles which are obtained during the mixing are electrostatically attracted to the surface of the carrier. Then, only the toner 2 is separated out of the mixture of the toner 2 with the charging member 1 and mixed with the carrier, so that the quantity of the spent component 3 becomes extremely small. Thus, the toner charged quantity is hardly lowered and the scattering of the toner is prevented for a long time, then the high definition image is obtained by the toner fully charged.

Abstract: PURPOSE:To accurately read the image of an original with high gradation even when the light quantity of a light source for irradiating the original is fluctuated by forming a means to correct the change of the light quantity and a means to perform shading correction unitarily. CONSTITUTION:A CCD 11 outputs the image signal of one line of a white reference board during one cycle of a synchronizing signal outputted from a processor 28. Also, a photodiode 16 receives light from a fluorescent lamp 10 transmitted by an optical fiber 17, and permits a current corresponding to the light quantity to flow on the input terminal on one side of a current multiplier 22. The current multiplier 22 outputs the current proportional to a value multiplied by an inputted current. The signal of the current is converted to a voltage value proportional to a current value by a voltage-current converter 21. The voltage is inputted to an A/D converter 24 as a reference voltage. In such a way, it follows that the A/D converter 24 performs the quantization of the reflecting light quantity of the white reference board and the light quantity of the fluorescent lamp 10 on the image signal, and data not depending on them is stored in a RAM 27.

Abstract: PURPOSE:To construct a developing device small and light by furnishing a sliding table whose tilting angle can be changed at two steps, lessening the dia. of a magnet roller, and supplying the developing agent collected from the magnet roller smoothly to a toner guide despite smaller level difference to the toner guide. CONSTITUTION:A sliding table 18 is furnished, whose tilting angle can be varied at two steps. Even though the dia. of an upper magnet roller 14a is small and the level difference between this and a toner guide 17b is lessened when a two-component developing agent 12 scratched off from the upper magnet roller 14a is to be supplied to the toner guide 17b, first the two-component developing agent 12 is dropped naturally by the upper sliding table 18a onto the lower sliding surface 18b. After the developing agent is deposited on the lower sliding surface 18b to a certain height, the developing agent 12 is allowed to fall naturally at all times owing to the level difference between the top of the deposited agent and the toner guide 17b. This enables constructing a high speed developing device small and light.
