Abstract: Only an information output from a wireless terminal for mobile unit to a wireless base station is allowed in response to an operation of operating means of the wireless terminal for mobile unit. When only the information output from the wireless terminal for mobile unit to the wireless base station has been allowed by the operation of the operating means, an information output from the wireless base station to the wireless terminal for mobile unit is allowed in response to another operation of the operating means. The wireless terminal for mobile unit is constructed so as not to respond to another operation of the operating means during the predetermined time since the first operation of the operating means.

Abstract: In a mobile system and a mobile management system, when an emergency notification that an urgent car 3 is approaching is transmitted from a base station 5 to a general owner-driven car 1, the distance between the general owner-driven car 1 and the urgent car 3 is calculated on the basis of the current position of the general owner-driven car 1 and the current position of the urgent car 3 under the control of a CPU 11. If the distance is within a predetermined value, the base station notifies the driver of the general owner-driven car that the urgent car is approaching.

Abstract: A lid (120), which is provided on a body of an acoustic device and moves as being able to open or close a front side thereof where an insertion slot is provided for inserting a recording medium, is moved by driving a motor (211) of a drive section (210) with an operation of an open/close button of a movement controller (234) of a movement control device (200). A temperature sensor (220) detects a temperature of a heading space of the lid on a movement path in a first direction, and the movement thereof is stopped when the temperature is within a predetermined temperature range. The movement is recovered when the predetermined temperature is not detected after a predetermined time has passed. When a contact sensor (233) recognizes the contact between the lid and an object to be contacted, the moving direction is reversed for only a predetermined time. When a temperature determining section (232) recognizes a temperature change within the predetermined time, the movement is restarted.

Abstract: An information providing apparatus includes a terminal device in a mobile body for transmitting an information request signal and an information providing device for transmitting information data to the terminal device in response to the information request signal. The information request signal is issued in response to an operation of starting the mobile body's engine.

Abstract: An advertisement information providing apparatus which is capable of enhancing the effectiveness of an advertisement. The apparatus selectively provides a terminal apparatus mounted in a mobile vehicle with the advertisement information about a shop which is relatively close to the current position of the mobile vehicle and has a merchandised product belonging to the advertised merchandised product genre desired by the user of the terminal apparatus.

Abstract: In a parts management system for a mobile unit, a detection unit is provided at the mobile unit and adapted to detect information related to management of parts of the mobile unit such as a vehicle. A service center management unit is provided at a service center and permitted to communicate to the detection unit. The service center management unit is adapted to produce information for a user of the mobile unit according to the information related to the management of the parts of the mobile unit and detected by the detection unit. An information unit is permitted to communicate to the service center management unit and adapted to send to the user of the mobile unit the information for the user of the mobile unit and produced by the seance center management unit.

Abstract: In a receiver for a mobile unit, a region and a frequency band of an available radio wave of the region are stored in ROM 4, and a region in which a mobile unit is located is detected from the present position measured by a GPS receiver 2 and receiving frequency bands of FM/AM bands are set to the receiver based on the detected result.

Abstract: An electronic volume varying apparatus for producing a controlling signal to control an electronic volume in response to pulses from a manually operable pulse generator, wherein it is prevented, when incorporated in a cassette deck or the like, that a listener is surprised with a great sound volume after cancellation of a muting mode. A muting judging section outputs a memory disabling signal when a muting-on signal is supplied thereto, and a memory enabling/disabling device is interposed between a pulse counting device and a memory device of a controlling section and stops its outputting of pulse count data from the pulse counting device to the memory device in response to the memory disabling signal from the muting judging section. A method and apparatus which can accurately detect an input pulse from a manually operable pulse generator as well as a pulse switch which eliminates inadvertent outputting of a pulse are also disclosed.

Abstract: A driving apparatus for opening and closing a lid which is provided to open or close a recording medium insertion opening of a recording medium player. When the lid does not reach a fully opened position or a fully closed position in a predetermined period of time after the starting of opening or closing drive of the lid, such a fault condition can be removed by inverting the direction of rotation of a driving motor. Moreover, the lid is driven in the closing direction after a predetermined period of time from the time when a recording medium is inserted into the recording medium insertion opening, or the lid is driven in the closing direction in response to a closing command. By these operations, it is made possible to prevent the lid from being left in a halfway closed position.
