A grommet is formed having a funnel shaped portion and a tubular portion linked to a small diameter end portion of the funnel shaped portion. The grommet is inserted to an aperture of a car body panel after a wire harness is passed through and attached to the funnel shaped portion and the tubular portion, and a body latch groove provided on the external circumferential surface of the funnel shaped portion is latched to the car body panel. An extended tubular portion is provided that projects from the tubular portion, and extends inside the funnel shaped portion. A plurality of ribs is provided on an external circumferential surface of the extended tubular portion. The ribs include type one ribs having grooves on both surfaces of an element linking the rib to the extended tubular portion, and a type two rib having no groove.

A plurality of first base images are formed from a base color output in accordance with a predetermined adjustment value. A plurality of first correction images are formed on the first base images from a correction color to be a subject for correction output in accordance with a predetermined adjustment value. The first correction images are displaced within a predetermined range. The first adjustment value is determined from changed adjustment values. The second base images are formed from the base color output in accordance with the predetermined adjustment value, and the second correction images are formed from the correction color output in accordance with a plurality of adjustment values determined based on the first adjustment value. The second adjustment value having an extreme is determined from a plurality of adjustment value candidates. Finally, the adjustment value for the correction color is corrected to the determined second adjustment value.

In an electrical junction box for an automobile vehicle, a casing includes upper and lower casing members. A lock section joints the upper and lower casing members. A vehicle attachment section extends outward from an outer surface of the casing above the lock section. A bracket projecting from a vehicle body is inserted upward into the vehicle attachment section to fix the electrical junction box onto the vehicle body. The electrical junction box comprises a lock protection section including right and left ribs that project from the outer surface of the casing on the opposite sides of the lock section so that the right and left ribs extend to a position higher than the lock section. A distance between the right and left ribs is set to be smaller than a width of the bracket. Then, interference between the bracket and the lock section is prevented upon insertion of the bracket to prevent a casing lock section of an electrical junction box from being damaged when the electrical junction box is secured to a vehicle body.

A fixed station and an on-board apparatus are constructed to carry out a short range communication. The on-board apparatus specifies an application from a command included in reception data received from the fixed station and starts a corresponding processing, when an acquired command is a menu selection command. A menu including commodities and charges are displayed. When a selected item is determined, the determined content is displayed. When an IC card unit receives an IC card for settling the charge, the charge is settled by rewriting the IC card by data exchange via wireless communication. A short range wireless unit is used to ensure individuality of the communication. This short range communication may also be used at a vehicle repair shop, at a curved corner on a travel path or the like.

When a vehicle-mounted device receives a FCM signal from a road-side communication device, the vehicle-mounted device receives or transmits a data signal in accordance with a link direction and a time slot specified by the FCM signal. When the vehicle-mounted device does not receive a signal to be received within an expected time, or when it transmits an ACK signal which is a last signal of communication, retry processing starts. In this retry processing, the vehicle-mounted device determines the contents of communication processing to be next carried out from both the contents of the signal transmitted from the road-side communication device and the contents of the last time communication processing.

A communication system for vehicles, which obtains exact communication processing with responders mounted on vehicles running on a road having a plurality of traffic lanes, is disclosed. An expressway has three traffic lanes. A gantry is disposed in a specified position on the expressway. On the gantry are disposed antenna units to counter the traffic lanes respectively. The antenna units are provided with communication areas by means of a pair of antenna elements respectively. The antenna element is composed of a microstrip array antenna disposed with eight pieces of patches laid out in two rows with four pieces in each row. The antenna units controls communication processing to communicate with vehicles adjoining each other. When response signals are sent from a vehicle mounted responder, the vehicle mounted responder is fixed and communication processing for toll collection is performed. As a result, communication processing with responders mounted on vehicles respectively which are running in the respective traffic lanes can exactly be performed.

A semiconductor integrated circuit, which can precisely measure the sleep time of a CPU by using a built-in oscillation circuit which does not utilize an oscillator to automatically activate the CPU, is disclosed. A communication control part of a responder mounted on a vehicle, which composes a toll road charging system, is composed of an LSI having a built-in CPU with a sleep function for automatically stopping operation clocks. The CPU is held in the sleep state for a certain time period from the time when the responder completes data communications with a ground station until the time when the responder exits the communication area of the ground station. The sleep time is measured by having a dividing counter downcount oscillation signals from a CR oscillation circuit built in the LSI. However, as the oscillation frequency of the CR oscillation circuit varies according to the operational environment, such as temperature, the CPU obtains the frequency error of the second clock pulses and correct the count value for sleep time measurement based on the reference clock pulses from a quartz oscillator, which becomes the operation clocks of its own, immediately before entering the sleep state.
摘要:
To enable communications between a vehicle-installed device and an antenna unit even when the vehicle-installed device passes through an area where neighboring communication areas overlap each other, a toll collection point of a multiple-lane express road is provided with a gantry having antenna units provided corresponding to the lanes. The antenna units are controlled so that neighboring units alternately transmit signals. The antenna units transmit signals according to a predetermined cycle and transmit an unmodulated carrier wave. Upon receiving a signal, a vehicle-installed device generates a response signal by using a control circuit and transmits a signal by reflection, fixes a communication party for further communications and assumes a status of waiting for an interrogation signal. If the vehicle-installed device receives pilot signals repeatedly from a single antenna unit, the device determines that the communications have failed, and cancels the fixation of communication party and invalidates the party to become able to communicate with other antenna units. The vehicle-installed device will communicate with one of the antenna units without a failure even if the device passes through an overlapping area, thus performing tolling processing without a failure.
