Publication number: 20240102957Abstract: In an electrochemical gas sensor (10), a first sensing element (21) is stored in a first storage portion (31). A moisture permeable film (24) is disposed in a first introduction inlet (31A) of the first storage portion (31). The moisture permeable film (24) substantially prevents a to-be-detected gas from permeating therethrough. A second sensing element (22) is disposed in a space into which water vapor and the to-be-detected gas contained in a target gas flow. In such a configuration, the electrochemical gas sensor (10) is capable of detecting a to-be-detected gas having a concentration of 0 or more and 1 ppm or less.Type: ApplicationFiled: March 8, 2022Publication date: March 28, 2024Inventors: Shinichiro KITO, Masayuki SEGAWA, Takahiro YOKOYAMA, Junya IMAIZUMI, Yuki MIZUTANI, Masahiro TANAKA, Yoshiko KUMAGAI

Patent number: 9909616Abstract: A ball joint includes a bearing seat in the form of a resin ball seat provided within a seat-accommodating portion of a metal socket for slidably and rotatably receiving a ball portion of a ball stud. An end portion of the seat-accommodating portion through which the stud portion passes extends towards the stud portion beyond the spherical center of the ball portion. The ball seat has a covering portion formed on the outer side of a seat opening portion of a ball-accommodating portion which has a spherical shape conforming to a sliding surface of the ball portion of the ball stud.

Patent number: 9546679Abstract: A bearing seat for a ball joint which simplifies the process of joining a housing and a bearing seat and makes it easy to guarantee the stiffness necessary for a ball joint as a whole by making it easy to fill the interior of an undercut groove with a softened or molten material and a ball joint having this bearing seat for a ball joint are provided. The ball joint 100 has a bearing seat in the form of a ball seat 130 which receives a ball portion 113 of a ball stud 110 inside a cast housing 120 so that the ball portion 113 can slidably rotate. The ball seat 130 has an undercut groove 140 in its outer peripheral surface which contacts the inner peripheral surface of the housing 120. The undercut groove 140 is formed so that the inner width W2 of its bottom portion 142 is greater than the opening width W1 of the opening 141 and so that its depth D is shallower than the opening width W1 of the opening 141.Type: GrantFiled: February 28, 2013Date of Patent: January 17, 2017Assignee: Kabushiki Kaisha Somic IshikawaInventors: Yasuhiro Sato, Masayuki Mizutani, Takashi Umei

Publication number: 20160177999Abstract: Provided is a ball joint in which a dust cover is fixed to a socket by a retaining ring and which has an improved waterproofing performance at a fitting region where the dust cover is fitted onto the socket. A ball joint 100 has a dust cover 140 fitted onto the outer periphery of a socket 120 formed into the shape of a cylinder with a bottom. The socket 120 has a dust cover groove 125 into which a socket-fitting portion 141 of the dust cover 140 is fitted, and a dust cover-receiving surface 126 for supporting a socket-facing surface 143 of the dust cover 140. The dust cover-receiving surface 126 inclines toward the socket-facing surface 143 while extending from the outer side toward the inner side. Radial projections 142 are formed on the inner peripheral surface of the socket-fitting portion 141 of the dust cover 140. Also, an axial projection 145 projecting toward the dust cover-receiving surface 126 is formed on the socket-facing surface 143 of the dust cover 140.Type: ApplicationFiled: May 15, 2013Publication date: June 23, 2016Applicant: Kabushiki Kaisha Somic IshikawaInventors: Masayuki Mizutani, Masaki Sobukawa

Patent number: 6092954Abstract: A bearing seat slidably supports a ball head of a ball stud in a housing. Circumferentially spaced-apart load bearing ribs on the outer surface of the bearing seat facing the housing support the load placed on the joint. Auxiliary load bearing ribs, between adjacent ones of the load bearing ribs, extend from the surface of the ball joint seat slightly less farther than the load bearing ribs. The auxiliary load bearing ribs come into supportive contact with the housing when subjected to heavier loads, to prevent excessive stress flexure of the bearing seat. The ability of the ball joint to absorb repeated heavy load applications while maintaining friction compensation and a stable torque without stress cracking is improved. The ball joint has an improved ability to compensate for dimensional tolerances, which facilitates component manufacture. The load withstanding ability and the durability of the ball joint are thus improved without an increase in size or cost.Type: GrantFiled: November 10, 1998Date of Patent: July 25, 2000Assignee: Kabushiki Kaisha Somic IshikawaInventor: Masayuki Mizutani

Patent number: 4658212Abstract: A connector terminal examination device includes a frame, an examination head mounted on the frame for linear movement in one and the other directions, a connector holder mounted on the frame at one side of the examination head and adapted to receive a connector inserted from the upper side thereof, and an operator disposed on the frame at the opposite side of the examination head to the connector holder and adapted to drive the examination head towards and away from the connector holder. The examination head has a plurality of probes projected forwardly therefrom. Each of the probes has a front probe portion and a rear probe portion slidably received in a metallic tube and independently biased forwardly such that a predetermined gap is formed between the probe portions when they are in the freed condition. The rear probe portion is electrically insulated from the metallic tube.Type: GrantFiled: December 26, 1984Date of Patent: April 14, 1987Assignee: Tokai Electric Wire Company LimitedInventors: Shinichi Ozawa, Masayuki Mizutani
