Title: Polarizing plate manufacturing method and liquid crystal display device
Inventor: TAGUCHI KEIICHI
IPC: G02B5/30
Filed: 2001-12-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an inexpensive long-sized polarizing plate of high quality which is made of an obliquely stretched polarizing film which enables improvement of the yield in a polarizing plate punching process and to provide a liquid crystal display device using the polarizing plate obtained by this method.  <P>SOLUTION: In the method for manufacturing the long-sized polarizing plate, a polymer film for polarizing film supplied to be stretched has the percentage of water content controlled to 1 to 10% before being brought into contact with a stretching heat roll, and thereafter, the polymer film is brought into contact with the stretching heat roll, which is placed obliquely to the film carrying direction and has the surface temperature of ≥80°C, while giving backward tension to the polymer film, and thus the polymer film is stretched to manufacture the long-sized polarizing plate. The polarizing plate obtained by this method is used in the liquid crystal display device.  <P>COPYRIGHT: (C)2003,JPO

IPC: F16H3/04
Filed: 2001-12-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide an automatic transmission of the same continuous engagement type as manually operated vehicles, in view of the fact that automatic (AT) vehicles with currently prevailing automatic transmissions are inferior to manually operated vehicles in the issue of reducing fuel consumption.  <P>SOLUTION: As an alternative to an example in which a difference in the speed of rotation between the center and outer periphery of a disc is obtained from gear ratio, a difference in the outer periphery caused by the opening and closing of an umbrella is used; to automate the opening and closing of the umbrella, a retaining ring 4 supporting a lifting rod 3 at each end is oppositely attached to a spline 2 on a main drive shaft 1, so that centrifugal forces acting on the lifting rod 3 with each increase in the rotating speed of the main drive shaft 1 cause swelling and rising at a center bent portion. The retaining ring 4 operatively connected thereto slides from both sides to reduce an interval while increasing the radius of rotation of each support claw 5 in the same way as the deployment of the umbrella. When the umbrella is deployed to its maximum, all the support claws 5 completely engage a driven gear 6, and the main drive shaft 1 and the driven shaft 7 rotate integrally with each other to complete a series of automatic shifts.  <P>COPYRIGHT: (C)2003,JPO

Abstract: A gear drive, including a first shaft, a first gear wheel on the first shaft, a second shaft a certain distance away from the first shaft, and a second gear on the second shaft. The second gear wheel engaged with the first gear wheel by way of helical gearing. A third gear wheel is mounted on the second shaft a certain axial distance away from the second gear wheel to compensate for backlash. The third gear wheel also engages with the first gear wheel by way of helical gearing and being axially shiftable with respect to the second gear wheel. An expansion element is arranged so as to change a distance between the second gear wheel and the third gear wheel as a function of temperature. The expansion element has a thermal expansion selected so that, when the expansion element undergoes thermal expansion, the expansion element shifts the third gear wheel in an axial direction along the second shaft and thus, due to a helical gearing effect, compensates for play caused by a thermally induced change in the distance between the first shaft and the second shaft.
