Abstract: A communication system including a communication box connected to a public communication line and capable of data communication with a child unit through a digital cordless (DCL) wave and with a multi-function device through a wires LAN (WLAN) wave, and wherein each of the child unit and multi-function device has a light emitting portion and a light receiving portion for optical communication between the child unit and multi-function device. The communication box and multi-function device have respective WLAN communication control portions which are normally placed in a non-operating state, and when the communication box receives facsimile data from the public communication line, the communication box commands the child unit to require the multi-function device to start its WLAN communication control portion, starts its own WLAN communication control portion, and transmit the facsimile data to the multi-function device through the WLAN wave.

Abstract: Whether the reception electric field level of the antenna #1 is higher than the predetermined level is judged. If the reception electric field level of the antenna #1 is not higher than the predetermined level, the communication mode is to be set to the multi-slot mode, and then whether the reception electric field level of the antenna #1 is higher is judged by comparison of the reception electric field level of the antenna #1 and the reception electric field level of the antenna #2. If the reception electric field level of the antenna #1 is higher, the call mode is to be set to the antenna #1 for executing transmission and reception, or if the reception electric field level of the antenna #1 is not higher, the communication mode is to be set to the antenna #2 for executing transmission and reception.

Abstract: An arrangement for measuring a quantity of intake air passing through an intake air duct by a sensing element disposed in parallel with a flow direction of the intake air. The sensing element includes a flow speed sensing resistor deposited on a base plate and formed into a film for sensing a flow speed of the intake air, and a pair of lead members deposited on the base plate and electrically connected to the resistor. The flow speed sensing resistor is arranged to form a temperature distribution of the resistor uniform in a direction parallel with and/or perpendicular to the flow direction of the intake air.

Abstract: The invention is directed to an arrangement for detecting a rotational angle of a rotating shaft by a sensor. The sensor includes a substrate and a detecting element which has a plurality of blocks of magnetoresistance element deposited on a planar surface of the substrate. The sensor also includes a magneto member which has a pair of magnetic poles facing each side end of the substrate respectively and providing a magnetic field covering at least the planar surface of the substrate. The sensor is so arranged that one of the detecting element and the magneto member is mounted on the rotating shaft, and the other is disposed at a certain position relative to the rotating shaft. Accordingly, the blocks of magnetoresistance element are disposed always in a uniform magnetic field, so that the rotational angle is detected accurately.

Abstract: A throttle body adapted to be mounted between an intake pipe and an intake manifold, the throttle body comprising an upstream body connected to the intake pipe and formed with a substantially horizontal suction passage; a downstream body connected to the intake manifold and formed with a downwardly inclined throttle bore, the throttle bore continuously extending from the suction passage on a downstream side thereof; a throttle valve rotatably mounted in the throttle bore of the downstream body; and a fuel injector mounted to the upstream body in such a manner as to inject fuel toward the throttle valve; wherein the fuel injected from the fuel injector collides with the throttle valve to be atomized and distributed in the downstream body, and is supplied to the intake manifold.
