IPC: B60C11/12
Filed: 1988-12-09
Abstract: PURPOSE:To improve the extent of abrasive resistance as well as to abate a sipe tear by forming an innermost layer among three steel belt layers into a hollow structure, and setting width of the three layers and width of the hollow part to a specified relationship, while extending an outer end of a sipe in the same side as the extending direction of a cord at the outermost layer. CONSTITUTION:An innermost layer steel belt layer 6 is formed into a hollow structure removing a central part in the tire width direction. In addition, width W1 of an intermediate layer steel belt layer 5 is made larger than each width W2 of other steel belt layers 4, 6, setting it to 80 - 110% of tread width W. Each width W2 of these innermost and outermost steel belt layers 4, 6 is set to 80 - 98% to the width W1 of the intermediate layer steel belt layer 5. Then, hollow width W3 of the innermost layer steel belt layer 6 is set to 15 - 50% with the width W1 of the intermediate layer steel belt layer 5. On the other hand, an outer end in the tire width direction of each sipe 10 is extended at the same side in the extending direction of a cord in the outermost layer steel belt layer 4.

Title: Photocatalytic device and illuminating fixture
Inventor: KAMATA HIROSHI
IPC: A61L9/20
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an illuminating fixture which can sufficiently develop the performance of a photocatalytic film. SOLUTION: A protective film 25 essentially comprising silica (SiO2) mixed with spherical fine particles of alumina (Al2O3) is formed as an undercoat on the outer face of a cover body 20. Then a photocatalytic film of titanium dioxide (TiO2) mixed with 0.1 to 10 wt.% of fine particles of tin dioxide (SnO2) is formed in the region which can be irradiated with light from a high pressure sodium lamp 22. By forming the protective film 25 with alumina exposed on the surface, the surface smoothness of the photocatalytic film 26 is improved, which prevents decrease in the transmittance caused by diffusing property of the photocatalytic film 26, thus enhancing photocatalytic properties.  By mixing tin dioxide into titanium dioxide in the photocatalytic film 26, most part of titanium dioxide becomes that of an anatase type because tin dioxide has a crystal structure similar to an anatase type, and tin oxide acts as the binder of titanium dioxide. This prevents microcracks in the photocatalytic film 26 and improves the hardness, photocatalytic property and transmittance.

Filed: 1992-10-26
Abstract: PURPOSE:To efficiently prevent lowering durability, due to the corrosion of a pressure vessel by the back flow of moisture to the pressure vessel, and the occurrence of an explosion accident, by preventing the back flow of pressure, less than given pressure, by an energization spring, interposed between a main valve and an auxiliary valve, and the check valve of the auxiliary valve. CONSTITUTION:The connection of the mouth tap of a pressure vessel to a valve device 19 pushes down a plunger 41 by a plunger operating rod 57 to provide communication between a nozzle hole 26 and a main valve operating hole 27. This makes the pressure fluid in the pressure vessel open an auxiliary valve 45, and pass through the through hole 33 of a bracket 34, the auxiliary valve operating hole, the main valve operating hole 27, and the nozzle valve 26 in order to be discharged. Although the lowering of the inner pressure in the pressure vessel causes the back flow of pressure fluid in the main valve operating hole 27 because of the opening of a main valve 40. But the auxiliary valve 45 is opened by pressure, and also a check valve 44 is closed by the energization force of a spring 56, preventing the back flow of pressure fluid to the pressure vessel.
