Patent number: 6460454Abstract: A heat-sensitive stencil master making system includes a thermal head having an array of a number of heater elements which extends in a main scanning direction substantially perpendicular to a sub-scanning direction in which the thermal head is moved relatively to heat-sensitive stencil master material when imagewise perforating the heat-sensitive stencil master material. Each of the heater elements is longer in the main scanning direction than in the sub-scanning direction.Type: GrantFiled: October 6, 1999Date of Patent: October 8, 2002Assignee: Riso Kagaku CorporationInventors: Hikaru Oike, Yukio Irie

Patent number: 6385344Abstract: An operator can select image processing for a half tone image area among a plurality of processing methods, and image processing appropriate for the image can be carried out thereby. An original image is read by an image sensor 1 and output through either simple binary conversion by binary conversion means 3 for character processing or half tone image processing by binary conversion means 2 for photograph processing. Judging means 6 judges whether image data are of a character image area or a half tone image area, and switches output between the binary conversion means 3 for character processing and the binary conversion means 2 for photograph processing. The binary conversion means 2 for photograph processing includes error diffusion processing means 10 and dither processing means 11. By setting of setting means 13 carried out by an operator, output from either the error diffusion processing means 10 or the dither processing means 11 is selected for a half tone image.Type: GrantFiled: May 11, 1998Date of Patent: May 7, 2002Assignee: Riso Kagaku CorporationInventors: Yukio Irie, Shinya Okada, Aya Nakadai, Yoshiyuki Okada

Patent number: 6359702Abstract: Image data for a margin around the image area of a book form original can be erased and image data for a book center portion are obtained without loss. In a photograph mode, a low threshold value is set in first binary conversion means 4, and image data having been input are binary converted by using this value. Based on the image data having been converted, a first coercion signal generating unit 6 judges a margin around the original image. A high threshold value is set to second binary conversion means 5 and image data having been input are binary converted by using this value. Based on the image data having been converted, a second coercion signal generating unit 7 judges a margin around the original and a portion including a book center portion. A character processing binary conversion unit 3 carries out binary conversion on input image data for the portion within the original, and outputs whitening data which erase the margin around the original.Type: GrantFiled: May 12, 1998Date of Patent: March 19, 2002Assignee: Riso Kagaku CorporationInventors: Yukio Irie, Shinya Okada, Yoshiyuki Okada

Patent number: 6357348Abstract: A heat-sensitive stencil master making apparatus for making a stencil master by imagewise perforating thermoplastic film of heat-sensitive stencil master material according to an image on an original includes a thermal head which has an array of a plurality of heater elements and is brought into thermal contact with the thermoplastic film. Heater elements selected from the array of the heater elements according to the image on the original are applied with an electric voltage so that perforations are formed in the parts of the thermoplastic film of the heat-sensitive stencil master material in contact with the selected heater elements.Type: GrantFiled: November 17, 1999Date of Patent: March 19, 2002Assignee: Riso Kagaku CorporationInventors: Jun Nakamura, Hideyuki Kinoshita, Yukio Irie, Kunio Nomura, Atsushi Takata, Shinichi Takizawa, Yoshiyuki Okada, Hikaru Oike

Patent number: 6330012Abstract: An image forming system includes a thermal head having a linear array of a plurality of heater elements extending in a direction of the main scanning, and a head driver which drives the thermal head on the basis of image data to selectively operate the respective heater elements according to image data while the thermal head is being moved relative to a recording medium in a direction of the sub-scanning, thereby forming a copy of the image represented by the image data on the recording medium line by line. The heater elements are divided into a plurality of head blocks which are contiguous in the main scanning direction, and the head driver is provided with a plurality of head drive segments of the same number as the number of the head blocks. Image data consisting of a plurality of pieces of line image data is stored in a memory. Each line image data consists of a plurality of image data fractions which are of the same number as the number of the head drive segments.Type: GrantFiled: May 17, 1999Date of Patent: December 11, 2001Assignee: Riso Kagaku CorporationInventor: Yukio Irie

Patent number: 5747502Abstract: The present invention relates to benzo?c!phenanthridinium derivative of the general formula A: ##STR1## wherein M and N individually represent a hydroxyl or lower alkoxy group, or M and N simultaneously represent a hydrogen atom or together form a methylenedioxy group, X.sup.- represents an acid residue or a hydrogen acid residue, and R represents a lower alkyl group, and a process for preparing such derivatives. The compounds exhibit both potent antitumor activity and platelet aggregation inhibition activity, and are expected to be useful for the treatment of tumors. The process has good reproducibility and may be effected under moderate conditions, and therefore the process is practically useful. In addition, hydrogen salts of the present compounds have an enhanced stability, which is an advantage in formulating the same into pharmaceutical preparations.Type: GrantFiled: March 16, 1992Date of Patent: May 5, 1998Assignee: Nippon Kayaku Kabushiki KaishaInventors: Miyoji Hanaoka, Hisao Ekimoto, Fumiko Kobayashi, Yukio Irie, Katsutoshi Takahashi, Masanobu Suzuki, Takeshi Nakanishi, Osamu Kogawa, Keizou Ishikawa
