Patent JP-S6310528-A (JP)
Title: Drying method
Inventor: MAEDA YORIHISA
IPC: H01L21/304
Filed: 1986-07-02
Abstract: PURPOSE:To dry a large batch of objects without the danger of a fire and prevent contamination of the objects by using organic vapor which is vaporized at a reduced pressure, under which organic substrates do not boil at room temperature by applying physical force to liquid of the surface of objects to be dried at a pressure of less than atmospheric pressure after making organic vapor contact the objects. CONSTITUTION:Organic substances are vaporized only at a reduced pressure. For instance, the pressure in a low pressure vessel 11 is decreased to 60 Torr in about 10 seconds by operating a rotary vacuum pump 12. While this operation is maintained, a valve 19 is slightly opened to introduce air into the low pressure vessel through a filter 20 so that the pressure can reach 40 Torr to prevent isopropanol 14 from boiling. After 5 minutes of such conditions a Si wafer 13 is brought in contact with isopropanol vapor. The valve 17 is closed and than the valve is fully opened to allow the internal pressure of the low pressure vessel 11 to return to the atomospheric pressure before the Si wafer is taken out by opening a door.

Title: High internal pressure/heavy loading pneumatic raidal tire
Inventor: TANAKA MAKOTO
IPC: B60C11/00
Filed: 1987-06-24
Abstract: PURPOSE: To improve resistance to partial wear, of the title tire for a bus and the like, by forming a shoulder portion outer contour, axially outside from a specific point on a tread, in a specific negative radius of curvature so as to form a shoulder falling to a specific correcting value.  
     CONSTITUTION: The inner/outer contours of a mould on a tread center portion, away from a tread center CL to a point of 0.64W0.85 times the half width of a tread, is formed at a positive radius of curvature R 1  having its center of curvature on the tire axis side, and the outer contour of a shoulder outside of this point is formed at a negative radius of curvature R 2 , 1W30 times a tread width. Furthermore, a tread shoulder portion falling correcting value H 2  is set at 0.05W0.04 times the head H 1  at a single tread crown radius of curvature. Hence the charge of operating internal pressure will cause the whole area of the outer contour to expand outwardly in the axial direction beyond the tread outer contour and its ground contacting shape in loading to be nearly rectangular. This constitution improve resistance to partial wear.

IPC: H01J11/44
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To suppress the coloring of a front glass substrate, even when silver is used in an electrode material by making a metal electrode out of silver under a condition that an amount of Fe2 O3 of the front glass substrate of a plasma display device, which provided with the metal electrode between the front glass substrate and a back glass substrate which are opposite to each other, is adjusted to be less than a specific value. SOLUTION: A content of Fe2 O3 in a front glass substrate used in this plasma display device, is less than 2,000 ppm, and a metal electrode is made of silver. The front glass substrate used in this plasma display device has low content of Fe<2+> ion, and a silver electrode is formed on the surface in a following process, so that coloring can be inhibited because the reduction amount is low even when Ag<+> ions diffused from the silver electrode, are diffused into the glass. Accordingly silver which is easily reduced and colloidized, can be used as the material for the metal electrode, and the electrode can be formed by screen printing with low cost.
