Publication number: 20130324193Abstract: A mobile telephone includes a cartilage conduction unit for making contact with the ear cartilage. The cartilage conduction unit is provided to at least one of two corner parts at an upper side of the mobile telephone. The mobile telephone can include a surface of an outer wall and a cartilage conduction vibration source arranged inward from the surface of the outer wall, the vibration of the cartilage conduction vibration source being transmitted to the surface of the outer wall, wherein when the surface of the outer wall is brought into contact with at least a part of the ear cartilage around the entrance part to the external auditory meatus without making contact with the auricular helix, the sound pressure inside the external auditory meatus at about 1 cm from the entrance part of the external auditory meatus has an at least 10 dB increase compared to the non-contact state.Type: ApplicationFiled: July 25, 2013Publication date: December 5, 2013Applicants: Rohm Co., Ltd.Inventors: Hiroshi HOSOI, Yoji HOSOI, Masashi MORIMOTO, Masahide Tanaka

Patent number: 8359846Abstract: An exhaust manifold includes: a double collecting pipe formed of inner and outer pipes; and an inner pipe retainer formed of a pair of semi-circular portions and a connecting portion. The inner pipe includes a collecting pipe portion and bifurcated branch pipe portions. The outer pipe covers outer peripheral portions of the collecting and branch pipe portions. The semi-circular portions are respectively connected to outer peripheral portions of branched branch pipe portions and an inner peripheral portion of the outer pipe. The connecting portion connects the semi-circular portions. The inner pipe retainer is interposed between the inner pipe and the outer pipe and is connected to the inner pipe and the outer pipe to define a certain gap therebetween. Exhaust gas from exhaust ports of a set of cylinders among a plurality of cylinders of an engine is introduced into the collecting pipe portion through the branch pipe portions.Type: GrantFiled: November 4, 2009Date of Patent: January 29, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Nobuyuki Murakami, Hiroshi Hosoi, Hitoshi Shimamura, Jin Wakamatsu, Katsumi Yagi, Kimihiro Jinno, Tatsuki Fukagawa

Patent number: 8341953Abstract: An exhaust manifold includes: a double collecting pipe having an inner pipe, including a collecting pipe portion and branch pipe portions, and an outer pipe, covering the collecting and branch pipe portions and thicker than the inner pipe; and an inner pipe retainer having semi-circular portions and a connecting portion, and thicker than the inner pipe and thinner than the outer pipe. The inner pipe retainer connects the inner and outer pipes with a gap therebetween. Exhaust gas from exhaust ports of a set of cylinders is introduced into the collecting pipe portion through the branch pipe portions. The total spot-welded area of the outer peripheral portions of the branch pipe portions and the inner peripheral portions of the semi-circular portions is larger than that of the inner peripheral portion of the outer pipe and the outer peripheral portions of the semi-circular portions.Type: GrantFiled: November 4, 2009Date of Patent: January 1, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Nobuyuki Murakami, Hiroshi Hosoi, Katsumi Yagi, Kimihiro Jinno, Tatsuki Fukagawa

Publication number: 20120289162Abstract: The present specification discloses an incoming/outgoing-talk unit having an ear-hook unit, a cartilage conduction vibration unit that makes contact with ear cartilage in a state where the hook unit is hooked to the ear, an outgoing-talk unit, and a unit for performing short-range wireless communication with the mobile telephone. Further disclosed is an incoming-talk unit having an ear-hook unit, and a cartilage conduction vibration unit for transmitting cartilage conduction from outside of ear cartilage in a state where the hook unit is hooked to the ear. Also disclosed is an incoming-talk unit having a three-dimensional viewing adjustment unit, a temple having a unit for adjusting contact of eyesight-adjusting eyeglasses with the temple when the unit is superposedly mounted on the eyesight-adjusting eyeglasses; and an audio information output unit provided to the temple.Type: ApplicationFiled: July 24, 2012Publication date: November 15, 2012Applicants: ROHM CO., LTD.Inventors: Hiroshi HOSOI, Yoji HOSOI, Masashi MORIMOTO, Masahide TANAKA

Patent number: 6626139Abstract: The present invention provides a gear mechanism of a power transmitting system, which includes a crank gear operatively coupled with a crankshaft, and a first driven gear that is coupled with a first balance shaft via a damping mechanism that allows relative rotation between the driven gear and the balance shaft. The damping mechanism includes a friction damper that generates frictional force when the first driven gear and a counter gear fixed to the first balance shaft rotate relative to each other within a predetermined rotational phase range or angle, and a stopper rubber or rubbers that elastically deforms to generate elastic force when the first driven gear and the first balance shaft rotate relative to each other beyond the predetermined rotational angle.Type: GrantFiled: June 22, 2001Date of Patent: September 30, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yuji Horita, Kouhei Hori, Makoto Ishikawa, Hiroshi Hosoi

Patent number: 4914344Abstract: A spark plug for internal combustion engines includes a third electrode in addition to a center electrode and a ground electrode which define a normal or main spark gap. Defined between the center electrode and the third electrode is an auxiliary gap adjoining the normal gap and adapted to produce a capacitive discharge at a voltage lower than that of the normal gap, and a discharge is induced across the normal gap by the capacitive discharge across the auxiliary gap.Type: GrantFiled: August 3, 1988Date of Patent: April 3, 1990Assignees: Nippon Soken, Inc., Toyota Jidosha Kabushiki KaishaInventors: Kiyohiko Watanabe, Toshihiko Igashira, Takeo Miyoshi, Masahiro Yamashita, Hiroshi Hosoi, Noboru Takagi
