Abstract: A plurality of radio relay stations 1 are connected so that bi-directional ring-like paths are made up of radio transmission paths. The respective radio relay stations 1 bidirectionally transmit data inputted from terminals placed thereunder onto the bidirectional ring-like paths respectively. The respective data are respectively received by radio relay stations 2 having data destination terminals placed thereunder along the bidirectional ring-like paths. Each radio relay station, which has received the data destined for the terminals placed thereunder from both directions, transmits earlier incoming data to each terminal placed thereunder and discards later incoming data. Thus, a radio relay system can be implemented which is capable of relaying data with a high degree of reliability.

Abstract: An apparatus automatically locks the doors of a vehicle based on mutual communications between a portable unit and a vehicle-side control unit. After the doors are closed and locked after all the passengers get off the vehicle, the user of a portable unit unlocks the doors in order to allow a person without the portable unit to fetch something left in the vehicle. After the person opens a door, takes whatever he or she needs, and closes the door, the doors are automatically locked. When a door sensor is operated to unlock the doors, and one of the doors is opened, a memory means stores information indicating that the portable unit is present in a predetermined range outside of the vehicle. If the memory means stores information that the doors are unlocked, then the doors are automatically locked.

Abstract: A request signal transmitted from LF antennas of a vehicle-mounted unit is received by a radio terminal through an LF antenna. In response to the request signal, the radio terminal transmits a response signal from an antenna. The response signal is received by an RF unit of the vehicle-mounted unit. The vehicular remote control device controls an operating state of a vehicle-mounted device depending on the judgment of a match between the response signal and identification information inherent in the vehicle. The radio terminal has a light-emitting diode. When the radio terminal receives a failure diagnosis signal that is transmitted instead of the request signal, the radio terminal does not transmit a response signal, but energizes the light-emitting diode.

Abstract: When a door sensor is touched, a vehicle-mounted unit and a portable unit performs mutual communications for authentication, and the doors are unlocked. When the door sensor is touched without intending to unlock the doors, wasteful consumption of electric energy is avoided which would otherwise result from mutual communications for authentication triggered by a request signal. When the door sensor may possibly be operated not for the purpose of unlocking the doors, e.g., when a CPU detects the doors as being already unlocked from a signal outputted from a door lock knob switch, a request signal is inhibited from being transmitted from the vehicle-mounted unit to the portable unit.

Abstract: The present invention provides a granulated powder coating composition prepared by granulating a starting powder coating composition having an average particle size of 10 .mu.m or less to an average particle size suitable for powder coating; and a process for preparing a granulated powder coating composition, comprising granulating a starting powder coating composition having an average particle size of 10 .mu.m or less to an average particle size suitable for powder coating.

Abstract: A heat exchanger has a plurality of flat tubes which alternate with fins, and the tubes and the fins are disposed one on another. Both ends of each tube are connected to a pair of right-hand and left-hand headers, in fluid communication with them. The headers have their ends closed with caps, and each cap has a pin integral with it so as to hold in place a bracket which is used to mount the heat exchanger on a structural base. The integral pins protrude upwards or downwards from the caps.

Abstract: A wire harness mounting structure for a motor vehicle door comprising a door frame and planar mounting means, detachably attached to said door frame at an internal side of its motor vehicle, having a wire harness mounted thereon and extending in a plane generally parallel to the door frame. The mounting means is either in the form of a covering board, or a combination of the covering board and an internal side board mounted between the vehicle door frame and the covering board, and, is either integrally formed with the covering board or independently, rigidly formed as in the case of an internal side board.

Abstract: Wire harnesses for connecting a number of electric devices mounted on an automotive vehicle are arranged on flat resin frame covers fixed to vehicle frames or directly on resin vehicle frames or most preferably on a resin vehicle body, in order to facilitate wiring of electric devices, reduce harness spaces without use of harness fixtures, and automatize wire harness manufacturing processes. The wire harness thus arranged is connected to electric devices by engaging each set of harness end terminals with each electric device connector attached to the vehicle frame.

Abstract: A wire harness can be replaced partly or in its entirety with a circuit board which is composed of an insulator substrate and a plurality of conductive strip members provided thereon. The above mentioned conductive strip members are arranged on the insulator substrate parallel with each other. This parallel arrangement of the conductive strips corresponds to bundling of wires in a wire harness. By providing branch paths extending from the conductive strip members, the circuit board can replace a substantial part of the wire harness.

Abstract: To facilitate wiring work of electric devices housed within an automotive vehicle door via a wire harness, connector windows are formed in the trim cover; the wire harness is fixed to the inside of the trim cover by inserting the harness connectors into the connector windows; electric device connectors are fixed to the door frame at positions corresponding to the connector windows; the trim cover is fixed to the door frame by inserting the electric device connectors into the connector windows side by side with the harness connectors; and the electric device connectors and the harness connectors are connected, respectively, from outside the trim cover.
