Patent number: 11898583Abstract: In a cushion mechanism of a gas cylinder, when the pressure of a gas in a first pressure chamber is less than or equal to a prescribed pressure, a valve body cuts off communication between the upstream side and downstream side of a discharge flow passage by mean of the biasing force of a spring member. In addition, when the pressure of the gas exceeds the prescribed pressure, the valve body is displaced to the downstream side of the discharge flow passage against the biasing force, thereby enabling communication between the upstream side and the downstream side of the discharge flow passage.Type: GrantFiled: July 20, 2020Date of Patent: February 13, 2024Assignee: SMC CORPORATIONInventors: Seiichi Nagura, Naoki Shinjo, Kazutaka Someya, Akihiro Kazama, Yusuke Mori

Patent number: 11619245Abstract: In a fluid circuit for an air cylinder connected to a switching valve provided with exhaust ports, a head-side pressure chamber is connected to the switching valve by a first pipe, and a rod-side pressure chamber is connected to the switching valve by a second pipe. A first restrictor is disposed at a connection point between the first pipe and the switching valve or in the vicinity of a first output port of the switching valve, and a second restrictor is disposed at a connection point between the second pipe and the switching valve or in the vicinity of a second output port of the switching valve.Type: GrantFiled: February 7, 2022Date of Patent: April 4, 2023Assignee: SMC CORPORATIONInventor: Naoki Shinjo

Patent number: 11421716Abstract: A gas cylinder includes supply passages for supplying, to an accommodation chamber, a part of gas supplied to a second port. When the pressure in a first pressure chamber is equal to or lower than a prescribed pressure, a valve element closes a discharge flow passage by the biasing force of a spring member and the pressure in the accommodation chamber. When the pressure in the first pressure chamber exceeds the prescribed pressure, the valve element is moved by the pressure in the first pressure chamber, against the biasing force and the pressure in the accommodation chamber, to thereby open the discharge flow passage.Type: GrantFiled: June 8, 2021Date of Patent: August 23, 2022Assignee: SMC CORPORATIONInventors: Youji Takakuwa, Naoki Shinjo, Akihiro Kazama

Publication number: 20210293258Abstract: A first position detection sensor and a second position detection sensor of a pressure booster detect the position of a first piston or a second piston. A fluid supply mechanism supplies a fluid to a first pressure-boosting chamber and/or a second pressure-boosting chamber. On the basis of the detection results of the first position detection sensor and the second position detection sensor, the fluid supply mechanism switches between performing an operation for supplying fluid to a first drive chamber and discharging fluid from a second drive chamber, and performing an operation for discharging fluid from the first drive chamber and supplying fluid to the second drive chamber.Type: ApplicationFiled: August 17, 2017Publication date: September 23, 2021Applicant: SMC CORPORATIONInventors: Hiroyuki ASAHARA, Kengo MONDEN, Naoki SHINJO, Seiichi NAGURA, Kazutaka SOMEYA

Patent number: 10927857Abstract: A fluid pressure cylinder driving device includes a switch valve, a high pressure air supply source, an exhaust port and a check valve. When the switch valve is at a first position, a head side cylinder chamber communicates with the high pressure air supply source, and a rod side cylinder chamber communicates with the exhaust port. When the switch valve is at a second position, the head side cylinder chamber communicates with the rod side cylinder chamber via the check valve, and the head side cylinder chamber communicates with the exhaust port.Type: GrantFiled: September 4, 2017Date of Patent: February 23, 2021Assignee: SMC CORPORATIONInventors: Youji Takakuwa, Hiroyuki Asahara, Kengo Monden, Aki Iwamoto, Naoki Shinjo, Kazutaka Someya, Akihiro Kazama

Patent number: 8611087Abstract: To cool a blade type server disposed in an air-conditioned room, the following arrangements are made. The first is at least one shell having a ventilation passage disposed in the air-conditioned room. The second is, the following are disposed in a ventilation passage: racks, in which blade type servers each composed of a case with slim boards housed therein are stacked; cooling coils each having a coolant passage and a cooling fin and cooling a passing air; and at least one fan unit having axial-flow fans placed therein and producing air currents in one direction. The third is the fan unit forces a cooling air to flow in one direction in the ventilation passage thereby to cool the servers in the racks. The cooling coils and racks are disposed alternately so that warmed cooling air after passing through the rack is cooled by the cooling coil and then cools the next rack.Type: GrantFiled: July 15, 2011Date of Patent: December 17, 2013Assignees: Fujitsu Limited, Fuji Furukawa Engineering & Construction Co., LtdInventors: Yoichi Sato, Kenji Tosaka, Mitsuo Hayashi, Akihiro Yasuo, Hideki Kimura, Kengo Ueda, Katsuhiko Nakata, Yoshihisa Iwakiri, Hitoshi Nori, Tomoaki Haneda, Mika Tokumitsu, Naoki Shinjo, Kouji Kuroda, Yoshihiro Kusano
