Publication number: 20190351175Abstract: In an oxygen concentrator, a housing has a through hole formed therein, and a handle portion provided adjacent to the through hole. The through hole is formed so as to extend toward an other side in an axial direction of the housing from a first opening, the first opening being defined at least by a back-side end of a top face portion, two extension portions, and an upper end of the handle portion, and has an interior space continuously extending between the first opening and a second opening defined at least by a lower end of the handle portion and an upper end of the back face main body portion and disposed on the other side in the axial direction with respect to the first opening.Type: ApplicationFiled: May 13, 2019Publication date: November 21, 2019Applicant: NGK SPARK PLUG CO., LTD.Inventors: Masanori SUDA, Taku HIRANO, Keiko NII

Publication number: 20190275278Abstract: A nasal cannula in which a pair of nostril inserts (130) are provided on a base (120) provided at the distal end of a tube (110) such that the nostril inserts (130) communicate with the tube (100). The base (120) and the nostril inserts (130) are integrally formed so as to elastically deform to an appropriate extent. The nostril inserts (130) have an appropriate length. When the nostril inserts (130) are inserted into the right and left nostrils, respectively, of a patient, the nostril inserts (130) hold at least one of the columna nasi and the nasal septum from opposite sides with an appropriate elastic force, whereby the nostril inserts (130) are attached to the nostrils.Type: ApplicationFiled: March 8, 2019Publication date: September 12, 2019Applicant: NGK SPARK PLUG CO., LTD.Inventors: Kyosuke Nakamura, Masakazu Nagasawa, Kiichi Gondo, Keiko Nii, Masanori Suda

Patent number: 8519306Abstract: A glow plug including a pressure sensor (830) and a heater (150). The glow plug includes a position-defining member which defines the positional relationship between the pressure sensor (830) and the heater (150) and has a coefficient of thermal expansion greater than that of the heater. The pressure sensor (830) is fixed at a predetermined sensor reference position relative to the position-defining member. The heater (150) is held by a heater-holding member (820) in such manner that an attachment position A of the heater-holding member to the heater can be displaced, with a change in external pressure, relative to a predetermined heater reference position defined by the position-defining member. A displacement transmission member (840) is arranged between the heater (150) and the pressure sensor (830) so as to transmit displacement of the heater (150) to the pressure sensor (830).Type: GrantFiled: March 27, 2009Date of Patent: August 27, 2013Assignee: NGK Spark Plug Co., Ltd.Inventors: Shinsuke Itoh, Shunsuke Maeda, Masanori Suda, Toshiyuki Matsuoka

Patent number: 6526822Abstract: A flow measurement device is disclosed, in which an accumulation of pollution substance onto a detection element is prevented, and which can measure a reverse flow similarly to a normal flow. On both ends of an outer wall 23 outer peripheral portion of a divided flow pipe 20 having a &OHgr;-shape pipe passage, there are oppositely formed an inlet port 25 and an outlet port 26, which open in faces orthogonal to a flow direction of a main flow M that is a detection object. Within the divided flow pipe 20, by a curved partition 27, plural branch flow passages 28a, 28b mutually branching and joining in the divided flow pipe 20 are formed.Type: GrantFiled: October 6, 2000Date of Patent: March 4, 2003Assignee: NGK Spark Plug Co., Ltd.Inventors: Shunsuke Maeda, Yoshihiko Kohmura, Takio Kojima, Yasuhisa Kuzuya, Masanori Suda, Takafumi Oshima

Patent number: 6474154Abstract: A flow rate and flow velocity measurement device. A part of a flow 10 in a main flow pipe 1, which is a detection object, is introduced into a passage of a divided flow pipe 2 and becomes a flow 11. The divided flow pipe 2 has a curved portion 2c or rather an inverted arc portion in which the flow is abruptly changed in direction or rather inverted by protuberances 2a, 2b formed preferably in symmetry in upstream and downstream sides of the curved portion 2c. Outside the main flow pipe 1, there is disposed on the bottom portion of the curved portion 2c of the divided flow pipe 2 a detection element 5 fixed to a support body 4 while protruding preferably 0.05-0.3 mm from flow passage faces 2e, 2f in the vicinity thereof. An opposed face 2d opposite to the detection element 5 protrudes toward the detection face so as to throttle the passage and to accelerate a flow speed at the element.Type: GrantFiled: January 5, 2001Date of Patent: November 5, 2002Assignee: NGK Spark Plug Co., Ltd.Inventors: Yoshihiko Kohmura, Shunsuke Maeda, Takio Kojima, Yasuhisa Kuzuya, Masanori Suda, Takafumi Oshima

Patent number: 6474177Abstract: A flow rate and flow velocity measurement device has a divided flow pipe (332) which is attached so as to be orthogonal to an intake pipe (1) of an engine, and into which a flow in the intake pipe (1) is introduced, an inlet plate (334) which extends in a direction orthogonal to a flow direction in the intake pipe (1) and forms a U-shape form pipe passage in the divided flow pipe (332) and a detection element (331) which is disposed so as to be exposed to a flow in the divided flow pipe (332) outside the intake pipe (1) and detects a flow rate and a flow velocity, wherein one end of the inlet plate (334) protrudes into the intake pipe (1) while passing a top opening of the divided flow pipe (332), and the divided flow pipe (332) has a flow passage structure symmetrical with the detection element (331) being made a center, so that an equivalent detection element (331) output is obtained in regard to both cases in which a fluid flows through the intake pipe (1) in a normal direction and a reverse direction.Type: GrantFiled: March 12, 2001Date of Patent: November 5, 2002Assignee: NGK Spark Plug Co., Ltd.Inventors: Shunsuke Maeda, Yoshihiko Kohmura, Takio Kojima, Yasuhisa Kuzuya, Masanori Suda, Takafumi Oshima
