Patent number: 8162636Abstract: A scroll type compressor has a fixed scroll member, a movable scroll member, an oil reservoir, a back-pressure chamber, an oil extraction passage, a flow passage, and a partition wall. The back-pressure chamber disposed behind the movable scroll member is in communication with a discharge chamber. The oil extraction passage having a regulating valve or a throttle connects the back-pressure chamber to the oil reservoir. The oil return passage and the flow passage connect the oil reservoir to a suction chamber, respectively. The flow passage introduces excess lubricating oil into the suction chamber when the level of lubricating oil in the oil reservoir becomes higher than a predetermined level. The partition wall disposed between the openings of the oil extraction passage for restricting lubricating oil from the oil extraction passage other than the excess lubricating oil collected in the oil reservoir from flowing to the flow passage.Type: GrantFiled: May 13, 2009Date of Patent: April 24, 2012Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Kenji Yokoi, Masao Iguchi, Kazuhiro Kuroki, Tatsuya Ito

Patent number: 5162838Abstract: A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.Type: GrantFiled: July 24, 1991Date of Patent: November 10, 1992Assignee: Hitachi, Ltd.Inventors: Tatsuki Inuzuka, Keisuke Nakashima, Toru Takei, Yasuyuki Kojima, Kyoichi Nomura, Shinichi Shinoda, Katsubumi Ouchi, Hideki Muroya, Eizou Ebisui, Norikazu Takahashi, Tomoe Sasayama, Hideo Nakazawa, Naoki Kinoshita, Yasunori Iwafuji, Takeshi Kobayashi, Hisashi Matsumoto, Hiroshi Kawamura, Tadashi Tamaoki, Shogo Matsumoto, Kenji Yokoi, Atuhiko Urusihara
