摘要:
A case with a connector integrally formed with a resin connector, and can be manufactured with a small number of processes is provided. The connector case includes a housing, a resin connector, and a ground terminal extending along an outer periphery of the connector. A terminal-side fixing portion extending backward from the ground terminal is crimped to or pressed over a housing-side fixing portion. When molds are closed after the housing and the ground terminal are placed in the molds for injection molding of the resin connector, a pressing portion formed on the mold presses the terminal-side fixing portion against the housing-side fixing portion to crimp or press the terminal-side fixing portion to or over the housing-side fixing portion. As a result, in the process for the injection molding of the connector, the ground terminal is fixed to the housing at the same time. The connector case with the ground terminal fixed to the housing can be manufactured in a small number of processes.

摘要:
In a method for producing a molded article having a resin part, the resin part is injection-molded to an opening of a main body part and the molded article has an excellent air-tightness between the resin part and the main body part. A foam sealant is attached to a peripheral portion around the opening of the main body part. Attached to the main body part is a retainer made of the same kind of resin as injected resin and adapted to keep the foam sealant compressed in its thickness direction. The main body part is placed within a mold so that the retainer is exposed inside a cavity of the mold. A molten resin is injected into the cavity of the mold. The injected resin and the retainer are integrated into the resin part.

摘要:
A contactor (20) has a joint portion (27) which is jointed to each contactor pad (32) of one wiring board (30) by using a solder at one end portion thereof and a connecting portion (24) which is dip-soldered in each through hole (35) of the other wiring board (33) at the other end portion thereof. A housing (1) is constituted by integrally molding a housing main body (1F) having a U-like shape as seen from a plane and a reinforcing bar portion (2) which connects intermediate portions of opposed parts (1A) and (1B) of the housing main body (1F) with each other. Cavities (3) are substantially linearly formed in the housing main body (1F) at predetermined intervals. The contactors (20) are inserted into cavities (3), and the contactors (20) are movably held in the housing (1) with a holding member.

摘要:
An on-vehicle device for road-vehicle communication includes a communication unit for exchanging information with an on-road device, and storage unit for storing necessary information. When a communication error occurs between the on-vehicle device and the on-road device, information regarding the communication error is stored in the storage unit. The vehicle device further includes a card read-write unit into which a control card is removably inserted. The control card has a storage area for storing the above-described error information and information necessary in the on-vehicle device. Via the card read-write unit, information stored in the storage unit is transferred to the storage area of the control card to be stored therein, and information stored in the storage area of the control card is transferred to the storage unit to be stored therein. Accordingly, when a communication error occurs between the on-vehicle device and the on-road device, information regarding the communication error is transferred from the storage unit to the control card, so that information regarding the communication error can be obtained from the on-road device via the control card.

A vehicle-carried unit for automatic toll-paying systems carried on a vehicle for automatically paying a toll from a plurality of IC cards through communication with an on-road unit installed on a road. The toll is calculated at an exit gate in accordance with predetermined toll information (step 432), and it is judged whether or not payment is possible in accordance with balance information of a plurality of IC cards stored in a storage circuit (step 434). In the case of being capable of payment, the toll is subtracted (step 486), and a payment signal is transmitted to the on-road unit (step 488). Because balances of a plurality of IC cards are stored as described above, it becomes unnecessary to stop at a tollbooth due to shortage in balance.
摘要:
A road/vehicle communication method for communication between a plurality of road devices, which are provided with a plurality of road antenna devices at respective gates, and a vehicle communication device, which is mounted to a vehicle and transmits and receives information to and from the plurality of road devices by radio waves, includes the steps of: when the vehicle passes through a first gate, the vehicle communication device receiving gate information which relates to the first gate and which is transmitted from a road antenna device of the first gate, and the vehicle communication device transmitting the received gate information at a second gate; the second gate receiving gate information from a plurality of vehicle communication devices, and computing a communication probability for each antenna device of the first gate when a number of received gate information corresponding to the first gate has reached a predetermined number; and comparing, for each road antenna device, the communication probability with a predetermined reference value, and detecting, as a malfunctioning road antenna device, a road antenna device for which a difference between the communication probability and the predetermined reference value exceeds a predetermined value. Accordingly, at the second gate, a malfunctioning road antenna device can be detected among the road antenna devices of the first gate, and measures can be taken with respect to the malfunctioning road antenna device.
摘要:
An apparatus for transmitting information for a vehicle notifies a user of a range which can be reached by a vehicle with the present balance in a card. A vehicle-mounted device transmits a response signal upon receiving an inquiry signal from a road device. If it is determined on the basis of the signal from the road device that the vehicle is passing through an entrance gate, an exit gate which can be reached with the present balance is calculated on the basis of vehicle type information stored, balance information, and a toll table. As the name of the calculated exit gate is displayed on a display unit, a reachable range is notified to the vehicle.
