Patent number: 10993018Abstract: Generation of a secondary sound source is inhibited, and a sound quality is improved. Included are a support fixed to a mount base, a speaker unit including a portion to be fixed, and a base casing holding the speaker unit, and the speaker unit is fixed to the support and the base casing with the portion to be fixed being sandwiched between the support and the base casing. With this configuration, the speaker unit will be held stably, a great oscillation from a diaphragm of the speaker unit is less transmitted to the parts other than the diaphragm of the speaker unit, to the member holding the speaker unit, or the like. Generation of a secondary sound source is inhibited, and a sound quality can be improved.Type: GrantFiled: November 9, 2015Date of Patent: April 27, 2021Assignee: SONY CORPORATIONInventors: Kohei Kikuchi, Yohei Fukuma, Nobukazu Suzuki, Kazuhiro Matsutani, Yoshio Ohashi, Yasuo Kawabata

Publication number: 20210041774Abstract: An image display unit according to an embodiment of the present technology includes an image display device, a primary shaft portion, a holding portion, a first acting portion, and a second acting portion. The primary shaft portion extends in a direction. The holding portion holds the image display device, and is connected to the primary shaft portion to be movable in parallel with the direction in which the primary shaft portion extends. The first acting portion is capable of moving the holding portion in a first direction extending in parallel with the direction in which the primary shaft portion extends. The second acting portion is capable of moving the holding portion in a second direction that is opposite to the first direction extending in parallel with the direction in which the primary shaft portion extends.Type: ApplicationFiled: January 9, 2019Publication date: February 11, 2021Inventors: YOHEI FUKUMA, YASUO KAWABATA, TORU NAGARA

Patent number: 10405100Abstract: A sound conversion efficiency and a sound quality is improved. Included are an oscillating element that is expanded and contracted in response to a drive signal, two oscillating bodies that are positioned on opposite sides across the oscillating elements, have end faces arranged respectively in contact with both ends of the oscillating element in an expanding and contracting direction, and are oscillated by expansion and contraction of the oscillating element, and an urging spring that urges the two oscillating bodies and press the end faces against both the ends, respectively. Thus, the oscillating element is expanded and contracted, and the oscillating bodies are oscillated with the end faces of the oscillating bodies urged by the urging spring being in contact with both the ends of the oscillating element in the expanding and contracting direction of the oscillating element.Type: GrantFiled: November 9, 2015Date of Patent: September 3, 2019Assignee: SONY CORPORATIONInventors: Yohei Fukuma, Kohei Kikuchi, Nobukazu Suzuki, Kazuhiro Matsutani, Yasuo Kawabata

Publication number: 20090020274Abstract: A heat diffusing device includes first and second metallic thin plates that are alternately laminated to each other, and that are joined along with an upper sealing metallic thin plate and a lower sealing metallic thin plate by diffusion joining so as to form a sealed space in an interior defined by the first and second thin plates and the upper and lower sealing metallic thin plates. A C-shaped groove defined by a steep wall face is formed at a wall face defining the sealed space due to a difference (?w) between the dimensions of the first metallic thin plates and the dimensions of the second metallic thin plates.Type: ApplicationFiled: July 15, 2008Publication date: January 22, 2009Applicant: Sony CorporationInventor: Yasuo Kawabata

Patent number: 7369459Abstract: A forward-looking sonar includes a transducer array which is divided into a first sub array and a second sub array, a first beamforming section for forming a first receiving beam with the first sub array, and a second beamforming section for forming a second receiving beam with the second sub array. The forward-looking sonar receives target echoes from a wide sounding area with these receiving beams. The forward-looking sonar further includes a position measurement section for determining the position of a target based on the direction of the target calculated from a phase difference between the echoes from the target received by the first and second receiving beams by a split-beam method and the distance to the target calculated from time needed for receiving the echoes after transmission.Type: GrantFiled: August 9, 2005Date of Patent: May 6, 2008Assignee: Furuno Electric Company, LimitedInventors: Yasuo Kawabata, Tokihiko Hamada, Hidetoshi Kaida
