Patent number: 10150491Abstract: An on-board device controls the speed of the control target train so that the control target train is set to a given speed-controlled state upon reception of an earthquake detection signal, the given speed-controlled state being a state in which the speed of the control target train is set to be equal to or lower than a reduced speed, or the control target train is stopped. A speed control part estimates an estimated position and an estimated timing at which the control target train is set to a speed-controlled state when a given brake is continuously applied, and controls the speed of the control target train based on the positional relationship between the estimated position and a recommended avoiding-train-existence section when there is a time allowance between the estimated timing and the estimated earthquake arrival timing.Type: GrantFiled: September 23, 2016Date of Patent: December 11, 2018Assignee: RAILWAY TECHNICAL RESEARCH INSTITUTEInventors: Akihiro Gion, Masahiko Samizo, Kazutoshi Sato

Publication number: 20080289720Abstract: A fuel filling apparatus is provided. The fuel filling apparatus comprises an overfilling protective valve arranged in a fuel gas supply path for supplying a fuel gas to an automobile. The overfilling protective valve further comprises a fuel gas path, a valve unit for opening and closing the fuel gas path by a valve body, a valve body displacement means for displacing the valve body according to a filling pressure of the fuel gas, and a temperature modulating unit for modulating a temperature of the valve body displacement means. Even though a difference between the temperature of the fuel gas and the operation temperature of the overfilling protective valve is large, the temperature of the valve body displacement means can be maintained within the preset temperature range by the temperature modulating unit and the overfilling protective valve can be exactly operated under the preset pressure.Type: ApplicationFiled: March 24, 2008Publication date: November 27, 2008Inventors: NAOYUKI TAKANO, Kazutoshi Sato, Kanji Omori

Patent number: 7231192Abstract: A high frequency receiver of the present invention has a mixer of which one input part is connected to an output part of a filter and the other input part is connected to an output part of a frequency-variable local oscillator, and an output terminal connected to an output part of the mixer. The mixer is an image rejection mixer. The filter has a moderated damping characteristic in a frequency where the image rejection mixer reduces an image. Therefore, a high performance filter is not required, and hence a low price is realized.Type: GrantFiled: October 30, 2003Date of Patent: June 12, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masanori Suzuki, Koji Nakatsuji, Sanae Asayama, Atsuhito Terao, Kazutoshi Sato
