Abstract: In a fuel tank level sensor 1 for measuring a remaining amount of fuel in accordance with a resistance value which is varied by moving a rheostat 1a utilizing a float 1c that vertically moves according to increase and decrease of the fuel in a fuel tank 2, change in resistance value of the rheostat 1a includes a linear range in which the resistance value linearly varies with the increase and decrease of the fuel, and a non-linear range in which the resistance value discontinuously varies under full-tank conditions where the fuel tank is substantially filled up with the fuel. Even upon undesirable increase of the resistance value of the rheostat 1a as a result of deposition of sulfides, the sensor 1 can always detect accurately that the fuel tank 2 is filled up.

Abstract: The invention provides a technique in which a plurality of different transaction services provided by a plurality of nodes constituting a distributed processing system can be searched efficiently, particularly provides name information to achieve various kinds of services in the distributed processing system efficiently. A first node accepts a name information retrieval request from a second node. The first node sends the name information retrieval request to a third node designated by a system definition. The first node acquires name information from the third node and stores the name information in a global cache. The first node retrieves name information based on the retrieval request from a local cache of the first node and the global cache and sends the name information to the second node.

Abstract: In a system for warning a failure to wear a seat belt to urge a vehicle operator to wear the seat belt, a sound emitter is activated when a vehicle speed is higher than a threshold level and the seat belt is not fastened. The sound emitter cyclically alternates between a sound emitting state and a silent state when activated, the silent state lasting for a period of at least three seconds each time. Because the silent state is interposed between sound emitting states and because the warning is not emitted when traveling for a short period of time at a low speed, for instance, in a parking garage or the like or when the vehicle is stationary, the annoyance to the vehicle operator is minimized while allowing the vehicle operator to be kept warned.

Abstract: New information is provided based on a photographic image received from a terminal. A congeniality determination server communicates with a user terminal through a public network and the Internet. The congeniality determination server receives a facial image at a communication module, a face's distinctive features based on each received facial image are extracted at a control module and a face type based on the extracted face's distinctive features is determined. Congeniality between two persons corresponding to the combination of the two face types determined from the two facial images is then determined. The congeniality determination server transmits the determined congeniality between two persons from the communication module to the terminal user.

Abstract: An electronic endoscope system includes an electronic endoscope and a processor to which the electronic endoscope is connectable. The processor includes a signal processor for displaying the images captured by the electronic endoscope, while adjusting the color balance thereof, and a memory holding an endoscope database. The processor further includes a CPU that retrieves endoscopic information from a memory of the electronic endoscope, which includes compensation data for white balance adjustment of the processor. The CPU registers the electronic endoscope with the endoscope database by storing the retrieved endoscopic information into the endoscope database when the white balance readjustment of the processor is required.

Abstract: Based on detected information from a start sensor, a rotational speed sensor (or a vehicle speed sensor), and an accelerator opening sensor, a simulated sound selector device controls a simulated sound source device to generate a simulated sound signal corresponding to an operating condition of an electric vehicle when it starts, runs and is accelerated or decelerated, and also controls a sound level switcher device to adjust the level of the simulated sound signal. The simulated sound signal which is generated by the simulated sound source device and adjusted in level by the sound level switcher device is amplified by amplifiers, which drive respective loudspeakers to produce simulated sounds. The sound level switcher device is also controlled based on an ambient noise level detected by a noise sensor.
