  • Publication number: 20230242192
    Abstract: In a deflector device, a deflector body is rotated with respect to a case. A restriction plate of the case covers a divide between the deflector body and the case. Foreign matter is accordingly suppressed from ingression between the deflector body and the case by the restriction plate.

  • Publication number: 20230242184
    Abstract: In a deflector device, a magnet is rotated when a deflector body is rotated, and a magnetic sensor also detects a rotational position of the magnet. Moreover, an interior of a housing body is partitioned by a motor base into a vehicle width direction outside of the interior and a vehicle width direction inside of the interior, with the magnet housed on the vehicle width direction outside of the interior of the housing body. The magnetic sensor is housed on the vehicle width direction inside of the interior of the housing body. This accordingly enables foreign matter ingression from the vehicle width direction outside of the interior of the housing body into the vehicle width direction inside thereof to be suppressed by the motor base, enabling foreign matter to be suppressed from reaching the magnetic sensor.

  • Patent number: 9471277
    Abstract: Data measured by PS-OCT is corrected in a non-linear manner to enhance the quantitative analysis capability of PS-OCT and permit accurate quantitative diagnosis, including diagnosis of disease stage of lesions, as a useful means for computer diagnosis. Even when retardation per PS-OCT 1 contains error and becomes noise and its distribution is not normal or symmetrical around the true value, measured data is converted using a distribution conversion function obtained by analyzing the characteristics of noise via Monte Carlo simulation to remove the systematic error and estimate the true value otherwise buried in noise and thereby correct the PS-OCT 1 image more clearly.

  • Patent number: 8818657
    Abstract: The shift control unit shifts the sub-transmission mechanism while changing the speed ratio of the variator in response to a change in the speed ratio of the sub-transmission mechanism so that the through speed ratio does not change after the through speed ratio is caused to reach the final through speed ratio by changing only the speed ratio of the variator if the speed ratio corresponding to the shift instruction from the driver is between a first speed ratio at which the sub-transmission mechanism is in the second gear position at the high speed side and the speed ratio of the variator is lowest and a second speed ratio at which the sub-transmission mechanism is in the first gear position at the low speed side and the speed ratio of the variator is highest when the manual mode is selected.

  • Patent number: 8718883
    Abstract: In a manual mode, a gear position of a continuously variable transmission is selected based on an input operation from a driver, a final through speed ratio is set based on the selected gear position and a variator and a sub-transmission mechanism are controlled to realize the final through speed ratio. Whether an input torque to the sub-transmission mechanism is positive or negative is determined based on an input torque to the sub-transmission mechanism when the manual mode is selected.

  • Patent number: 8676454
    Abstract: The shift control unit executes a control to cause the through speed ratio to follow the final through speed ratio by changing only the speed ratio of the variator if a shift instruction is given from the driver a plurality of times in a row when the manual mode is selected, and advances the start of a change in the speed ratio of the sub-transmission mechanism or accelerates the progression of the change of the speed ratio as compared with the case where the manual mode is not selected when the speed ratio of the variator is maximized or minimized and the through speed ratio cannot follow the final through speed ratio.

  • Patent number: 8666616
    Abstract: A transmission control unit reduces a hydraulic pressure of a release-side frictional engagement element which is to be released of a sub-transmission mechanism and reduces this reduction amount as an input torque to the sub-transmission mechanism increases at the time of starting a shift when a manual mode is selected, the input torque is positive and the sub-transmission mechanism is to be shifted down.

The method for manufacturing an optical fiber preform comprises dehydrating the optical fiber soot preform by lowering the optical fiber soot preform within the muffle tube and passing through a heating region, pulling up the dehydrated optical fiber soot preform to the predetermined position, and sintering the optical fiber soot preform by lowering the optical fiber soot preform again within the muffle tube and passing through the heating region where temperature of the heating region is higher than temperature of the heating region in dehydrating; wherein A?B is satisfied where A is pull-up speed (mm/minute) of the optical fiber soot preform during the pulling up and B is gas flow rate (mm/minute) within the muffle tube at room temperature during the pulling up. Furthermore, 1.5×A?B is satisfied.
