Title: Manufacture of solid state image pickup device and solid state image pickup device
Inventor: KAWASHIMA HIKARI
IPC: H01L27/14
Filed: 1991-09-10
Abstract: PURPOSE:To improve a light condensing efficiency and light sensing uniformity by a method wherein a microlens pattern is made of base material having photosensitivity and, after the parts of the pattern are exposed to change the thermosoftening points of those parts, microlenses are formed by thermal flow. CONSTITUTION:A microlens base material film 9a made of main chain decomposing type polymer is formed on a semiconductor substrate 10. After the edge parts of microlens forming part are removed on light shielding films 8 provided between respective optoelectronic transducer parts and a microlens pattern 9b are formed, the required parts of the microlens pattern 9b are exposed. The thermosoftening point of the main chain decomposing type polymer is lowered when the main chains are decomposed by exposure. Therefore, the exposed regions 9d and the non-exposed regions 9c have different thermosoftening points. By applying heat to obtain a temperature between those thermosoftening points, microlenses 9 whose curvatures are controlled can be formed. With this constitution, a light condensing efficiency and uniformity of sensitivity can be improved.

Title: Image forming device
Inventor: MIYASAKA TORU
IPC: G03G15/08
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To restrain secular density fluctuation and irregular density at the time of recording a solid image by setting the rotational circumferential speed of a developing roll higher than the surface speed of a photoreceptor and setting the rotating speed of the developing roll so that toner amount supplied to the photoreceptor may be larger than the toner amount by which sufficient image density is obtained. SOLUTION: The rotational circumferential speed of the developing roll 1 is set to be higher than the surface speed of the photoreceptor 10, and the rotating speed of the roll 1 is set so that the toner amount supplied to the photoreceptor 10 by the roll 1 may be larger than the toner amount by which the sufficient image density is obtained. Furthermore, developing bias is set so that the toner amount at the time of developing may be smaller than the toner amount supplied to the photoreceptor 10 by the roll 1. Thus, when the toner adhesive amount of a toner thin film on the roll 1 is reduced with time, the rate of the shifting of the toner on the roll 1 to the photoreceptor 10 is increased because of the lowering of the electrification amount, so that the toner amount by which an electrostatic latent image on the photoreceptor 10 is developed becomes stable in substance.

IPC: H04N19/625
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To provide the image data processing unit in which production of an overflow is effectively suppressed without deteriorating the image quality. SOLUTION: In quantization sections 202-1 to 202-n, a plurality of quantization indices including maximum quantization indices are used for quantization and a code length at the quantization level is obtained. An object code length decision section 206 obtains a final object code amount S206 to satisfy the object code length based on the code length above. Simultaneously in the case that the code length is longer than the object code length even when the maximum quantization index is in use, it is discriminated that an overflow takes place. A binary search section 208 obtains a quantization index S208 satisfying the final object code amount. A quantization section 3 uses the quantization index S208 to conduct quantization.

Title: Apparatus for polishing beans
Inventor: SUGIHARA TADAAKI
IPC: B02B3/08
Filed: 1988-10-17
Abstract: PURPOSE:To well polish beans in spite of a short stirring feed length by a method wherein beans are polished while bean grains and polishing buffer materials are stirred and fed by a trough and a stirring escape feeder having escape parts each larger than each bean grain. CONSTITUTION:Beans are polished while bean grains and polishing buffer materials are stirred and fed by a trough 2 and a stirring escape feeder 3 having escape parts 3b each larger than each bean grain. That is, since a part of bean grains and a part of the polishing buffer materials are escaped toward the start end in a feed direction, a feed speed becomes slow and beans receive relatively much polishing action and, though a stirring feed length is short, polishing becomes well. Further, by preventing the application of overload to beans during stirring feed, it can be well prevented that beans are damaged.

Title: Transfer belt cleaning device
Inventor: NANJO YUZURU
IPC: G03G15/16
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent the reverse contamination of a transfer sheet by applying an electric field capable of injecting charges of the same polarity to toner in cleaning by a fur brush. SOLUTION: When the toner on a transfer belt 2 is charged, for example, negatively, a negative voltage of about -1.0 to -1.5kV, for example, is applied to a fur brush 5 by a high voltage power source 6. Therefore, when the toner reaches a toner removing part where a driving roller 4 is adjacent to the fur brush 5, the charging quantity of the toner is increased in negative direction by the voltage applied to the fur brush 5, and a part of the toner is removed by the mechanical force of the fur brush 5. The toner not removed by the mechanical force of the fur brush 5 because of its strong attractive force to the belt 2 and left on the belt 2 after passed through the toner removing part is carried to a transfer part again by the belt 2.  Even when the transfer paper is supplied at this time, the charging quantity of the toner is increased in negative direction to enhance the electrostatic force acting between the toner and belt 2, so that the toner left on the belt 2 is prevented from being adhered to the reverse side of the transfer paper.
