Title: Optical fiber preform, method for manufacturing the same and optical fiber by using the optical fiber preform
Inventor: KOMURA YUKIO
IPC: C03B37/018
Filed: 2001-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a large-size optical fiber preform from which an optical fiber with high quality can be produced. SOLUTION: The optical fiber preform 1 is manufactured by forming a glass layer 3 around a center layer 2 to form a porous preform and sintering the porous preform while dehydrating and removing impurities. In the process of manufacturing the glass preform 1, the density of the surface part of the glass layer 3 is controlled to >=0.3 g/cm<3> and <=0.4 g/cm<3> in the process of depositing the glass layer 3. By this method, a gas to remove impurities can easily flow through the glass layer 3 in the succeeding process of removing impurities, and thereby impurities can be easily removed. The concentration of total impurities of aluminum, titanium and vanadium in the surface part of the optical fiber preform can be controlled to >=0.2×10<3> ng/cm<3> and <=16×10<3> ng/cm<3> . Unnecessary crystals are prevented from growing from the impurities as nuclei on the surface of the optical fiber preform 1 and an optical fiber with high quality can be produced.

Title: Device and method for preventing hunting between ranges in continuously variable transmission
Inventor: BRIAN D CRASS
IPC: F16H61/02
Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent hunting between ranges in a continuously variable transmission. SOLUTION: A transmission assembly has the continuously variable transmission, a mechanical transmission for selecting a first gear range and a second gear range, and a control device receiving the input of an operator and outputting an output control command for the continuously variable transmission. The control device executes a first shift between the first gear range and the second gear range at a shift pointing response to the command. The control device puts the transmission in a first operation mode and inhibits a second shift from the second gear range to the first gear range. When the output power exceeds the shift point by a first value or when the command is lower than the shift point by a second value, the control device puts the transmission in a second operation mode allowing the second shift from the second gear range to the first gear range.  When the transmission is in the second operation mode and the output power reaches the output power of the shift point, the control device executes the second shift from the second gear range to the first gear range.
