摘要： To achieve an integration of components and the rationalization of the default opening mechanism of the throttle valve, a reduction of the load of the motor drive and a stabilization of the throttle control operation. In a default opening setting mechanism with which the default opening of the throttle valve 24 is maintained to be larger than the fully closed position when the electric current does not pass through the motor 12 driving the throttle shaft 18, the throttle lever 3 and the sleeve 45 are inserted and fixed, and the sleeve 42 united together with the return lever 2 is engaged with the sleeve 45 so as to be enabled to rotate in relative to the sleeve 45. The sleeve 42 is energized by the return coil in the close direction of the throttle valve 24 up to the initial opening position. This energized operation enables the return lever 2 to be coupled with the sleeve 3. A force for opening the valve for keeping the default opening the throttle valve 24 is energized by the spring 5 onto the throttle shaft 18 near the fully closed position.

摘要： According to one embodiment, a radio communication apparatus includes a transmitting and receiving section, a preamble detecting section, a data detecting section, and a response-time setting section. The transmitting and receiving section transmits an inquiry signal to a radio tag and receives a response signal returned from the radio tag. The preamble detecting section detects, within a period set with reference to transmission timing of the inquiry signal, a preamble included in the response signal returned by the radio tag that receives the inquiry signal. The data detecting section detects, when the preamble is detected, data included in the response signal. The response-time setting section sets, according to a parameter peculiar to the apparatus, a response time from the reception of the response signal from the radio tag until the transmission of the next inquiry signal to the radio tag by the transmitting and receiving section.

摘要： An RFID interrogator device has a transmission section for transmitting a command to an RFID tag and a reception section for receiving an RF signal from the RFID tag and is configured to perform backscatter radio communication with the RFID tag. The RFID interrogator device comprises a time window setting section configured to set a time window at timing of receiving preamble data added to a head of response data transmitted from the RFID tag in response to the command, and an identifying data storage section storing preamble identifying data. The RFID interrogator device compares the data received within the time window, with preamble identifying data stored in the identifying data storage section, thereby determining whether the data received is identical to the preamble data transmitted from the RFID tag.

摘要： A motor-driven airflow control device is provided wherein an inductance-based non-contact rotation angle sensor is compactly formed at an end of a throttle shaft. An exciting conductor is attached at an end of a rotating shaft to which a throttle valve is attached, a window hole is provided on a gear cover, a stationary substrate with energizing and signal-generating conductors formed thereon is attached to the gear cover so as to face the exciting conductor on the rotating shaft side through the window hole, and the window hole of the gear cover is covered by a thin shield member. The energizing and signal-generating conductors can be shielded from a space where the exciting conductor of the rotary member is arranged, making it possible to obtain a highly reliable motor-driven airflow control device including an inductance-based non-contact rotation angle sensor which is not affected by environments on the rotary member side.

摘要： The present invention provides a spread illuminating apparatus which can ensure uniform brightness over its entire screen. A light reflection-diffusion layer is formed on a light conductive member at a face provided with an optical path conversion means. Light emitted from spot-like light sources is reflected efficiently by the light reflection-diffusion layer toward a transparent substrate, and light intensity degrades in a substantially linear manner with the increase in distance from respective spot-like light sources. Sharp change of brightness on an observation surface can be prevented due to the light intensity degrading linearly.
