摘要:
An on-vehicle communication device capable of suppressing a delay in providing information, avoiding congestion, and sufficiently securing transmission power, includes a communication controller to controls a transmission cycle and transmission power when data is transmitted from a transmitting/receiving device. The communication controller uses its own vehicle information and surrounding vehicle information to estimate a degree of risk and a safe distance of its own vehicle. The communication controller controls the transmission cycle of its own vehicle based on a communication channel utilization rate of its own vehicle, a communication channel utilization rate of a surrounding vehicle and the degree of risk of its own vehicle, and controls the transmission power of its own vehicle based on the communication channel utilization rate of its own vehicle, the communication channel utilization rate of the surrounding vehicle and the safe distance.

A remote control system for a car-mounted device capable of realizing communication performance required for a keyless function and communication performance required for a smart function while suppressing increase in circuit scale. The remote control system includes a portable unit and an in-car unit. The portable unit includes: a function judgment mechanism judging whether the keyless function or the smart function is used; an amplification mechanism controlling transmission power in response to a result of judgment obtained at the function judgment mechanism; and a system clock generator controlling a transmission band in response to a result of judgment obtained at the function judgment part. The in-car unit includes: an in-car function judgment mechanism judging whether the keyless function or the smart function is used; and in-car system clock generator controlling a receiving band in response to a result of judgment obtained at the in-car function judgment mechanism.

An on-vehicle communication device according to the present invention includes initial signal estimating unit 243b for estimating initial data based on a part of the transmission command signal from the mobile device. Thus, it also includes PN signal generating unit 243c for generating a PN signal based on the initial data estimated by the initial signal estimating unit, and partial correlating unit 243d for calculating a correlation value between the transmission command signal from the mobile device and the PN signal. Thus, it also includes a data demodulating unit 244 for demodulating the transmission command signal from the mobile device, the starting of the data demodulating unit being controlled based on the correlation value calculated by the partial correlating unit 243d.

A filter for flitrating molten resin of the invention includes: a cylindrical filtering member formed with a large number of projections and recesses; and radially arranged rods in a supporter for supporting the cylindrical filtering member at arc-shaped projected portions, and is constructed such that molten resin material is allowed to pass through the filtering member at arc-shaped recessed portions. In this arrangement, it is possible to enhance the resistance of thermoplastic molten resin filter against filtering pressure as well as to ensure a large filtering area. Further, the filter may be constructed such that the cross-section of the aforementioned cylindrical member is made greater from the upstream side toward the downstream side. By this configuration, the flow rate of molten resin passing through the unit area of the filtering member is made uniform and consequently the collecting capacity of foreign substances is increased.

A traffic volume estimating apparatus 1A estimates the traffic volumes of traffic apparatus, and a traffic flow presuming apparatus 1B presumes the traffic flows generating the estimated traffic volumes. A presumption function constructing apparatus 1C corrects the presumption functions of the traffic flow presuming apparatus 1B on actually measured traffic volumes, traffic flow presumption results and control results. A control result detecting apparatus 1G detects the control results and the drive results of the traffic apparatus. Further, a control parameter setting apparatus 1D sets control parameters on traffic flow presumption results, and corrects the control parameters according to the control results and the drive results.
摘要:
In a serial two-stage extruder, the first-stage extruder has a screw including a feed screw section having a length within a range of 5 to 9 the major diameter thereof, a mixing screw section having a hexagonal cross section and a pitch of 1 to 3 times the major diameter thereof, and a metering screw section having a screw groove of an appropriate depth. The second-stage extruder includes an extruding screw and a barrel. The extruding screw has a screw groove of an appropriate depth and a dulmage formed at the tip end of the screw. The dulmage has a plurality of fins cooperating with fins of the barrel. Alteratively, in the second-stage extruder, the dulmage may have a plurality of axially spaced stages of fins. Configurations of the fins in each respective stage are identical but various characteristics of the fins vary from stage to stage. In this case, the barrel does not have fins.
