Patent number: 5926627Abstract: In an electronic apparatus with a separably combining main body and expander, a pair of movable claws which are interlocked with an opening/closing lever are provided on an upper surface of the expander and a pair of fixed claws are provided on the opposite side of the opening/closing lever. A connecting connector is arranged at an intermediate position of the pair of movable claws. A retaining lever for blocking an opening of the opening/closing lever in a closed state of the opening/closing lever is provided. A first detector detects an opening/closing state of the opening/closing lever and a second detector detects the position of the retaining lever. A connecting state of the main body and the expander is synthetically discriminated on the basis of signals from the two detectors and a connection signal of the connector for connecting the main body and the expander.Type: GrantFiled: April 22, 1997Date of Patent: July 20, 1999Assignee: Canon Kabushiki KaishaInventor: Hideo Sugimura

Patent number: 5166397Abstract: This invention relates to a process for producing an optically active cyclobutylamine which comprises reacting a racemic modification of cyclobuthylamine represented by the following general formula [I]: ##STR1## wherein R.sup.1 and R.sup.2 represent each a hydrogen atom or a protecting group; with an optically active N-acylphenylglycine to thereby give two corresponding diastereomeric salts, crystallizing the more difficultly soluble diastereomeric salt and isolating the corresponding optically active cyclobutylamine from the diastereomeric salt thus crystallized. The optically active substances of the compound of the above general formula [I] are useful as, for example, an intermediate in the synthesis of 9-[(1R, 2R, 3S)-2,3-bis(hydroxymethyl)-1-cyclobutyl]guanine which is expected as an antiviral agent.Type: GrantFiled: September 10, 1991Date of Patent: November 24, 1992Assignee: Nippon Kayaku Kabushiki KaishaInventors: Kazuhisa Narita, Masashi Nagai, Hideo Sugimura, Yukihiro Sagawa, Akira Shiozawa

Patent number: 5105203Abstract: A thermal transfer recording apparatus adapted to record an image on a recording medium by transferring a heat-transferable ink from a transfer medium to the recording medium. The apparatus has a transfer medium having on one surface a layer of a heat-transferable electroconductive ink formed on a base sheet, a recording head for heating the transfer medium in accordance with an image signal, and an electrode disposed in physical contact with the ink surface of the transfer medium so as to form a path from the electrode medium through which electric current is allowed to flow. Therefore, the apparatus prevents any path for electricity from being formed between the transfer medium and the recording head.Type: GrantFiled: January 22, 1991Date of Patent: April 14, 1992Assignee: Canon Kabushiki KaishaInventors: Nobuyuki Kuwabara, Kou Hasegawa, Hideo Sugimura, Kazuhiro Nakajima, Haruhiko Moriguchi

Patent number: 4917851Abstract: A method of manufacturing a multi-layer resin material by employing a plurality of kinds of thermoplastic resin. Resins for inner and outer layers are supplied into a feed block of a feed block type T-die coextrusion apparatus where they are laid up another, and are then sent to the T-die side. In this case, a resin which is practically similar to the resin for the outer layer is supplied as an auxiliary resin to both lateral edges of the multi-layer resins within the feed block. Thus, the sheet extruded from the T-die slit has lateral edges which are made of a single resin.Type: GrantFiled: May 22, 1986Date of Patent: April 17, 1990Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Toyokazu Yamada, Masao Miyama, Hideo Sugimura, Takeshi Shinohara
