摘要:
An air pressure detecting device serves to detect the air pressure of a wheel of a vehicle which has a tire tube disposed in a tire, the air pressure detecting device is disposed between the tire tube and the rim of the wheel portion for detecting the air pressure of the tire. The air pressure detecting device has a pressure bearing plate held in contact with the outer surface of the tire tube, a pressure sensor for detecting a pressure of the pressure bearing plate, and a detecting and transmitting unit for detecting pressure information from the pressure sensor, converting the pressure information into an electric signal, and transmitting the electric signal as a radio wave. The pressure bearing plate, the pressure sensor, and the detecting and transmitting unit are superposed in the order named. The components including the pressure bearing plate, the pressure sensor, and the detecting and transmitting circuit can be installed without the need for a special modification of the tire tube and the rim. As a result, the cost of the air pressure detecting device can be reduced.

Occurrence of significant difference of transmission rate between communication zones can be prevented to maintain the transmission rate of overall network uniform. The radio network system includes a plurality of radio communication control units are connected with each other via radio main line, and each radio communication control unit has a communication function with at least one radio communication terminal arranged within own communication area. Each of the radio communication control units includes means for broadcasting a transmission rate restriction demand to all of other radio communication control units and all of radio communication terminals when data amount stored in a transmission and reception buffer exceeds a predetermined threshold value, and means for lowering a transmission rate when a transmission rate restriction demand is received from any other radio communication control unit within a predetermined period and for increasing the transmission rate when no transmission rate restriction demand is received from any other radio communication control unit.

The outer periphery of a heat resistant roll comprises a para aromatic polyamide fiber. The heat resistant roll is applied for conveying and picking up a steel plate heated to a high temperature. The heat resistant roll is preferably applied to the inside of a continuous annealing apparatus for annealing the steel plate or to the exit side of this apparatus. The heat resistant roll is also preferably applied to the exit side of a baking furnace in a continuous coating apparatus for coating the steel plate. The heat resistant roll is also preferably applied to the exit side of a galvanization tank in a zinc galvanizing apparatus.

To provide a node (an optical transmission apparatus) enabling expanding the upper limit of the number of nodes capable of automatically forming a squelch table generated in advance in a BLSR system. For the above purpose, when generating a squelch table, hop counts counted from an add node or a drop node are used in place of a node ID of the own, as information of the add node, the drop node, etc. to be transmitted and received using a squelch data link. Thus, it becomes unnecessary to transmit and receive two information sets, a source node ID and a destination node ID, as conventionally required. By this, the number of bits available for identifying nodes can be expanded, enabling expansion of the number of nodes for which a squelch table can be formed automatically.

A tire air pressure detecting device has a tire air pressure detecting device on a wheel. A main transmitting device is provided at the wheel for transmitting an air pressure signal SP to a vehicle body. A main receiving device is provided at the vehicle body for receiving the air pressure signal SP. A main switch turn-on detecting device is provided on the vehicle body for detecting the turn-on of a main switch. A second control device is provided on the vehicle body for receiving the air pressure signal SP and a main switch ON signal Son. An auxiliary transmitting device on the vehicle body transmits a transmission instruction signal SR to the wheel when the second control means receives the main switch ON signal Son. An auxiliary receiving device on the wheel receives the transmission instruction signal SR. A first control device is provided for reading a new air pressure signal SP. When the main switch is turned on, the state of the tire air pressure can immediately be recognized. The main transmitting means is not required to transmit the air pressure signal at all times or increase the frequency with which to transmit the air pressure signal. Thus, the consumption of the battery at the wheel can be reduced.

To provide a power supply cord securement structure in order to finalize simple securement without incurring cost as much as possible when embedding the structure into the device body as a final product while the power supply cord connected to the electronic device is detachably secured in the assembly process, to prevent stress related cutting and wear due to transfer during the assembly process and transport between factories. In a power supply cord securement structure to secure and constrain the bush 14 by providing a nearly L shaped notch 12b on the chassis wall 12a where another electronic device 16 embedded into the electronic device and the electronic circuit substrate 17 provided on the electronic device main body are mounted, detachably securing the power supply cord with a securement structure in which the depressed section 14a close to the bush 14 of the power supply cord 13 is inserted, and obstructing the open side of the securement structure by edge 11a of the open section 11 formed on the body wall of the electronic device in the final assembly process of the electronic device.
摘要:
A wheel includes a disk form wheel, a tire fitted to the wheel, and a tire tube contained between the wheel and the tire, and is provided with an air pressure detection device intermediately disposed between the tire tube and the wheel. A metallic line form reception antenna is inserted by molding into a front fender. Since the distance from a transmission means fitted to an air pressure sensor to the reception antenna is reduced, reception sensitivity can be enhanced. In addition, since the reception antenna can be pitched to about the size of the fender, the reception sensitivity can be enhanced. Further, since jigs for fixing the antenna are needless, a reduction in the number of component parts can be contrived, and the antenna can be fixed without spoiling the appearance.
