Publication number: 20210107335Abstract: There is provided a passenger compartment structure that can save power while ensuring thermal comfort of an occupant. The passenger compartment structure allows control of thermal comfort of the occupant in a posture seated on a seat. The passenger compartment structure includes a layered structure constituting at least part of an interior member disposed at a position where the interior member is able to face a lower leg of the occupant. The layered structure disposed in each of a front middle portion, a front lower portion, a frontal lower portion, and a right surface front upper portion having a high geometric factor for the lower leg includes a surface layer, a structural parent layer, and a temperature control mechanism layer interposed between the surface layer and the structural parent layer.Type: ApplicationFiled: February 26, 2019Publication date: April 15, 2021Applicant: MAZDA MOTOR CORPORATIONInventors: Kazuya YOKOTA, Hiroya OCHIAI, Toshihiko OHSUMI, Junji KANEISHI, Tomohiro YOSHIZUE, Toshihiro KASHIMA

Publication number: 20200406708Abstract: A vehicle compartment temperature control device includes: a first interior member including a temperature control mechanism layer that can adjust the temperature of a leg of the occupant in a first region, that is, a front portion and the like. The vehicle compartment temperature control device also includes a second interior member disposed above the first interior member and including a temperature control mechanism layer in a second region, that is, a steering and the like that can adjust the temperature of a part above the leg and is different from the temperature control mechanism layer in the first region. The vehicle compartment temperature control device also includes an ECU. The ECU performs control such that the temperature of the temperature control mechanism layer in the first region is higher than the temperature of the temperature control mechanism layer in the second region.Type: ApplicationFiled: February 26, 2019Publication date: December 31, 2020Applicant: MAZDA MOTOR CORPORATIONInventors: Kazuya YOKOTA, Hiroya OCHIAI, Toshihiko OHSUMI, Junji KANEISHI, Tomohiro YOSHIZUE, Toshihiro KASHIMA

Patent number: 10146233Abstract: Provided is a flow rate ratio control device that even in change periods during which the actual flow rates of component gases change along with a change in the target total flow rate or target mixing ratio of mixed gas, can keep the actual total flow rate or actual mixing ratio of the mixed gas constant. Target flow rates set in flow rate control devices have continuous change periods during which target flow rate values continuously change from pre-change to post-change target flow rate values, respectively and correspondingly; and the time lengths of the continuous change periods are set to at least a followable time during which a flow rate control device of which a response speed to an actual component fluid flow rate is lowest allows the actual component fluid flow rate to substantially follow the target flow rate in the continuous change periods.Type: GrantFiled: April 5, 2016Date of Patent: December 4, 2018Assignee: HORIBA STEC, Co., Ltd.Inventors: Toshihiro Kashima, Kohei Honda, Tatsuya Hayashi

Patent number: 8851105Abstract: An object of this invention is to provide a superior mass flow meter or the like that can flexibly cope with a change of a sample fluid such as a gas kind without requiring a special troublesome labor and that can measure a flow rate with high accuracy. The mass flow meter comprises a sensor section that detects a flow rate of a sample fluid flowing in a flow channel, a setting section that sets a flow rate characteristic function that is intrinsic to each fluid to determine a flow rate based on a flow rate detected value output by the sensor section and an instrumental error correction parameter that is independent from the flow rate characteristic function and common to multiple sample fluids to correct an instrumental error of each mass flow meter, and a flow rate calculating section that calculates a flow rate measurement value of the sample fluid by applying the flow rate characteristic function and the instrumental error correction parameter to the flow rate detected value.Type: GrantFiled: March 12, 2010Date of Patent: October 7, 2014Assignee: Horiba Stec, Co., Ltd.Inventors: Toshihiro Kashima, Yutaka Yoneda, Yasuhiro Isobe

Patent number: 5683059Abstract: A bobbin for superconducting coils, which is made of a fiber-reinforced plastic material containing: (1) a matrix resin; (2) a polyethylene fiber having a negative thermal expansion coefficient in the fiber lengthwise direction, the angle between the polyethylene fiber and the longitudinal axis of the bobbin being in the range of .+-.35.degree. to 90.degree.; and (3) a substance having an elastic modulus higher than that of the polyethylene fiber. The bobbin of the present invention is useful for superconducting coils because it only exhibits a quite low degree of deformation, even when used under external stress at cryogenic temperatures.Type: GrantFiled: April 12, 1996Date of Patent: November 4, 1997Assignees: Toyo Boseki Kabushiki Kaisha, Tokyo Electric Power Co., Ltd., Toshiba CorporationInventors: Tsukushi Hara, Masahiko Nakade, Takeshi Ohkuma, Kenji Tasaki, Takashi Yazawa, Hideaki Maeda, Eriko Yoneda, Shunji Nomura, Toshihiro Kashima, Atsuhiko Yamanaka
