摘要:
When an internal combustion engine including a plurality of cylinders is operating steadily, an index value relating to an actual hydrogen content in exhaust gas downstream of a portion where exhaust passages from the cylinders merge, and upstream of a catalyst is detected. When an index value relating to the actual hydrogen content in the exhaust gas is larger than a determination index value relating to a hydrogen content corresponding to a permissible limit of air-fuel ratio variation, it is determined that there is abnormal air-fuel ratio variation between the cylinders.

A wireless resource allocation control system for allocating and releasing wireless resource used for communication between vehicles in a predetermined area is provided. The control system includes a unit mounted on a vehicle, and the unit includes a transmitter for transmitting first information associated with the vehicle. A station receives information from the unit and sends information to the unit. The station calculates a priority level for each of the units on the basis of the first information transmitted from each of the units, ranks the units in the order of the priority level, allocates wireless resources to the units in descending of the priority levels, and releases the wireless resource previously allocated to the unit in the case of the unit unworthy of current allocation of the wireless resource.

A pedestrian navigation system provides distance information and travel directions to a destination. The system includes a pedestrian navigation device for navigating a pedestrian's route by means of a vibration, a server for offering navigation information to the pedestrian navigation device, a network for connecting the pedestrian navigation device with the server to permit communication between each other, and a GPS for offering position information to the pedestrian navigation device. Further, the pedestrian navigation device can include a speaker for outputting a guide voice based on the user's present position information, so as to start a voice guide after generating vibration, thereby facilitating verification of the guidance information provided.
摘要:
In a dye-sensitized photovoltaic device including a semiconductor fine particle layer 2 on which a sensitizing dye is adsorbed, a counter electrode 3, and an electrolyte layer 4 between the electrodes, a molecule having a plurality of acid functional groups for adsorption onto the semiconductor electrode is used as a molecule of the sensitizing dye, and part of the acid functional groups is neutralized with an alkaline compound which is a hydroxide of at least one metal or compound selected from the group consisting of Li, Na, K, tetramethylammonium, tetraethyl ammonium, tetrapropyl ammonium, tetrabutyl ammonium, an imidazolium compound, and a pyridinium compound. In this manner, a dye-sensitized photovoltaic device that can achieve high photoelectric conversion efficiency even in the cases where a dye containing readily aggregating acid functional groups, such as carboxylic acid, as the adsorbing groups is used. A method for making the device is also provided.
摘要:
A multi-band antenna is adapted to operate in a first frequency band and a second frequency band which is higher than the first frequency band. A first antenna element is adapted to operate in the first frequency band, and has a first end which is electrically connected to the power feeding point and a second end which is electrically made open. A second antenna element is adapted to operate in the second frequency band, and has a third end which is electrically connected to the power feeding point and a fourth end which is electrically connected to the ground conductor. An electrical length of the first antenna element is set to ½ wavelength of the second frequency band, and an electrical length of the second antenna element is set to ¼ wavelength of the first frequency band.
摘要:
A display unit displays a route search result. A memory unit stores route search criteria including a destination. A route-search-result obtaining unit obtains, when a route search instruction including a designated location is received while the route search result is displayed on the display unit, the route search result with the designated location as a departure point and the destination included in the route search criteria stored in the memory unit as an arrival point.
摘要:
In a dye-sensitized photoelectric transfer device having a semiconductor layer and an electrolyte layer between a transparent conductive substrate and a counter conductive substrate, the semiconductor layer is composed of titania nanotubes, and a sensitizing dye is retained by the titania nanotubes. The titania nanotubes preferably have an anatase-type crystalline form. The dye-sensitized photoelectric transfer device is used as a dye-sensitized solar cell.
