Publication number: 20240077832Abstract: A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Akira Yoshimura, Kazunari Murayama, Susumu Nittani, Atsushi Numagami

Publication number: 20190240890Abstract: A process of producing a hollow resin-molded article includes: arranging covers on inner walls of mold halves, the covers having shapes corresponding to the inner walls; introducing a pair of sheets of thermoplastic resin each facing the cover arranged on the inner wall of a corresponding mold half; blowing air into a space between the sheets to cause the sheets to respectively contact the covers arranged on the inner walls, and thereby fusion-welding the sheets to the covers; and closing the mold halves; and cooling down the covers and the sheets in a state where the mold halves are closed. In the step of arranging, there are uncovered portions of the inner walls that are not covered by the cover. In the step of closing, there are mold contact portions of the sheets that respectively contact the uncovered portions directly and the mold contact portions are fusion-welded to each other in an overlapping manner.Type: ApplicationFiled: February 4, 2019Publication date: August 8, 2019Inventors: Takeharu YOSHIHASHI, Kotaro TANAKA, Masaki WAKAO, Susumu MURAYAMA, Nao SATO, Toshiharu FUKUSHIMA

Patent number: 8488221Abstract: Display image data for displaying images on a screen, and when display image data that has undergone specified gradation conversion is received, the characteristics of the output brightness displayed on the screen is checked. In the area for which the output brightness of the display image data is convex at the bottom in relation to the image data gradation values, the display image data gradation values are corrected so as to have a roughly linear relationship between the gradation values and the output brightness. Printing image data is generated based on the post-correction image data and an image is printed. In the area for which the output brightness bottom is convex, by performing this kind of correction, it is possible to print an image with an impression closer to the display on the screen. As a result, it is possible to print images on the monitor screen easily and without losing the impression received from the image displayed on the monitor screen.Type: GrantFiled: March 22, 2006Date of Patent: July 16, 2013Assignee: Seiko Epson CorporationInventors: Nao Ozawa, Susumu Murayama, Seishin Yoshida

Patent number: 7672029Abstract: In printing using a plurality of chromatic color inks of different lightness interchangeable with one another in color reproduction, ink consumption is reduced while preserving the quality of the printed result. On the basis of first color data represented in terms of density of a first reference color, second color data represented in terms of density of a plurality of second reference colors is generated. The plurality of second reference colors are the ink colors. They include two same hue reference colors of different lightness interchangeable with one another when reproducing a certain color. The lookup table holds the first color data and the second color data associated with one another. For a set of densities of a plurality of second reference colors representing achromatic color of higher lightness than the reference lightness, density of the same hue reference color having lower lightness is 0.Type: GrantFiled: February 22, 2006Date of Patent: March 2, 2010Assignee: Seiko Epson CorporationInventor: Susumu Murayama

Publication number: 20080216684Abstract: In an aspect, a first ink amount relating to the yellow ink is smaller than both a second ink amount relating to the cyan ink and a third ink amount relating to the magenta ink. In another aspect, a first total increase amount is larger than both a second total increase amount and a third total increase amount. The first total increase amount is a total increase amount of inks other than the yellow ink relating to a black yellow gradation. The second total increase amount is a total increase amount of inks other than the cyan ink relating to a black cyan gradation. The third total increase amount is a total increase amount of inks other than the magenta ink relating to a black magenta gradation. In another aspect, a first lowest brightness is lower than both a second lowest brightness and a third lowest brightness. The first lowest brightness is lowest brightness of color to be printed without using black ink on a black yellow gradation.Type: ApplicationFiled: March 10, 2008Publication date: September 11, 2008Applicant: Seiko Epson CorporationInventors: Masako Horai, Susumu Murayama

Patent number: 7355748Abstract: A client controls printing of color chips (images for colorimetry) with a plurality of tones for individual color inks (printing colorants). The client acquires from a server a tone value correction table (color matching information) to match standard colors. The server can acquire the lightness data of color chips for individual inks and create the tone value correction table based on the lightness data of color chips of individual color inks and the lightness data of standard colors corresponding to the color inks, and subsequently send the color matching information to the client. As a result, it is easier to produce colors that match standard colors.Type: GrantFiled: February 26, 2002Date of Patent: April 8, 2008Assignee: Seiko Epson CorporationInventors: Yoshifumi Arai, Susumu Murayama

Patent number: 5997198Abstract: A sheet feeder, or a printer incorporating the sheet feeder, has separation pads for separating a sheet to be fed by sheet feed rollers from the next sheet and a roller spring which produce urging force smaller than that produced by a spring of the separation pad. Idle rollers are brought into contact with the separation pads by means of the roller spring, thereby preventing the lowering of the next sheet. A sheet reset lever is pivoted so as to return the next sheet to a hopper. As a result, the sheet sheets stacked on the hopper in an inclined state is fed one by one through use of a separation pad method without increasing force for driving rollers and a back tension.Type: GrantFiled: October 22, 1997Date of Patent: December 7, 1999Assignee: Seiko Epson CorporationInventors: Susumu Murayama, Atsushi Nishizawa, Masaki Shimomura, Narihiro Oki, Tsuyoshi Tomii, Toshikazu Kotaka
