| 20100290050 | Hydrogen Sensor - A hydrogen sensor includes a thin film layer formed over a substrate of resin or the like, and a catalyst layer formed on a surface of the thin film layer. When contacted by leaked hydrogen gas, the catalyst layer quickly hydrogenates the thin film layer through its catalytic action, thereby causing a change in optical reflectance of the thin film layer. The hydrogen sensor includes a protective film formed at least either between the substrate and the thin film layer or on a surface of the catalyst layer. | 11-18-2010 |

| 20100166614 | HYDROGEN-GAS CONCENTRATION SENSOR AND HYDROGEN-GAS CONCENTRATION MEASURING DEVICE - A hydrogen-gas concentration sensor comprises a substrate, and a plurality of hydrogen detecting films formed on the substrate, adjacent to one another. The hydrogen detecting films have a thin film layer, and a catalyst layer formed on the thin film layer. Each catalyst layer, when in contact with a hydrogen gas, exerts photocatalysis to hydrogenate each thin film layer reversibly and causes the electric resistance value thereof to change reversibly. The individual thin film layers have different sensitivities of a change in the hydrogen gas concentration vs. a change in the resistance value and different hydrogen gas concentration measurement ranges. The hydrogen-gas concentration sensor measures the hydrogen gas concentration with a thin film layer having a high sensitivity when the hydrogen gas concentration is low, and measures the hydrogen gas concentration with a thin film layer having a wide measurement range when the hydrogen gas concentration is high. | 07-01-2010 |
| 20100054999 | HYDROGEN SENSOR AND HYDROGEN GAS DETECTING APPARATUS - A hydrogen sensor includes a thin film layer formed on a top surface of a planar optical transmission medium, and a catalyst layer formed on a top surface of the thin film layer. A first interface is created between the planar optical transmission medium and the thin film layer. A substrate is joined to a bottom surface of the planar optical transmission medium so that a second interface is created between the planar optical transmission medium and the substrate. On entering a first end portion of the planer optical transmission medium, light from a light source is spread by an entrance section, and the spread light is transmitted inside the planar optical transmission medium to a second end portion by being reflected by the first and second interfaces alternately. Light exiting from the second end portion is transmitted to an optical sensor by an exit light-collecting section. If the thin film layer is hydrogenated by the catalyst layer contacted by hydrogen, the amount of light reflected from the first interface reduces. Hydrogen gas is detected by the optical sensor detecting such reduction in the amount of light. | 03-04-2010 |
| 20090193921 | SPEED CHANGE OPERATION APPARATUS FOR A VEHICLE - A speed change operation apparatus for a vehicle can comprise an operating lever for performing speed change operation of a transmission of a vehicle by a pivotal operation of the operating lever. An operating knob can be secured on the tip end of the operating lever and adapted to be gripped by a driver of vehicle. A push knob can be mounted on the operation knob and adapted to be actuated by a driver to descent a lock-pin rod arranged within the operating lever. The push knob can be outsert-molded by soft resin at its first portion abutting the lock-pin rod when the push knob is actuated or at its second portion abutting the operating knob after the actuation of the push knob. | 08-06-2009 |
| 20090135425 | HYDROGEN GAS DETECTION DEVICE - In a hydrogen gas detection device, light emitted from a light source is irradiated onto a hydrogen sensor whose reflectance (optical reflectance) varies upon contact with hydrogen gas, and the light transmitted through the hydrogen sensor or reflected by a reflective film of the hydrogen sensor is received by an optical sensor. On the basis of the signal output from the optical sensor and indicative of the amount of light received, the hydrogen gas detection device detects leakage of hydrogen gas. | 05-28-2009 |
| 20090087691 | Electric Power Generation Device - An electric power generation device includes a cell body and a secondary electric power generator. The cell body has an electrolyte, a fuel electrode and an air electrode. The secondary electric power generator is joined to at least one of the fuel and air electrodes and includes P- and N-type thermoelectric conversion members. With the electric power generation device, the cell body generates electric power at temperatures higher than or equal to an power generation start temperature, and at the same time, the P- and N-type thermoelectric conversion members joined to the cell body and functioning as a thermocouple produce electric power by utilizing the Seebeck effect. | 04-02-2009 |
| 20090000414 | SPEED CHANGE OPERATION APPARATUS FOR A VEHICLE - A speed change operation apparatus for a vehicle for performing speed change operation of a transmission of a vehicle by a pivotal operation of an operating-lever shaft can comprise a body adapted to be mounted on a vehicle and an operating-lever shaft pivotally supported on the body. A metal core member can be rotated by pivotal operation of the operating-lever shaft. Coils can be arranged along a pivotal trajectory of the core member and can have a voltage applied thereto. Shift positions of the operating-lever shaft can be detected by variations of voltage caused by movement of the core member in the coils. | 01-01-2009 |
