IPC: G06T11/00
Filed: 1990-10-08
Abstract: PURPOSE:To execute a clip process as a whole graphic process system efficiently by adopting a clip frame processible by a graphic display device as the reference of the execution judgement of a clip process simulate means when displaying graphic data. CONSTITUTION:A graphic process system 20 calls out a graphic data display area judging means 24 to the coordinate-transformed graphic data. The graphic data display area judging means 24 judges whether simulating the clip process or not in the graphic process system 20 before executing a clip process function in a graphic display device 30. In case having judged to simulate the clip process, a graphic data transfer means 26 is called out after calling a clip process simulate means 25, and in case having judged not to simulate the clip process, the graphic data transfer means 26 is called out. Thus, the performance of the clip process as the whole graphic process system 20 including the graphic display device 30 is improved.

IPC: B60C9/18
Filed: 1984-12-21
Abstract: PURPOSE:To improve the durability of a radial tire in a radial tire by using the steel cord with preset propert when a car runs on a semi-good road in a radial tire in which two or more belt layers reinforced by a steel cord are imbedded between a tread section and a carcass ply. CONSTITUTION:A radial tire is formed by sequentially laminating first to third belt layers 3, 2, and 1 in each of which a steel cord is imbedded in parallel to rubber from a carcass ply 6 side. The cord direction of each layer makes a comparatively small angle against the equatorial surface of the tire and at least a set of adjacent belt layers 3 and 2 are arranged so that the cord directions can be mutually intersected at an angle of 15 deg.-30 deg.. In this case, in the belt layers 3 and 2 in each of which the cord is imbedded in the direction where the layers are intersected by each other except the outermost layer 1 of the belt layers 3 to 1, the steel cord has a Young's modulus of 6,000-16,000kg/mm<2> and a bending rigidity of 150-250g and is set so that the initial elongation can be less than 0.2 in the rubber-covered state where the cord is removed from the tire.

Title: Web-supporting roller
Inventor: DAGURASU REEN BURANDEINGU
IPC: B65H27/00
Filed: 1992-10-07
Abstract: PURPOSE: To minimize a risk that a web is damaged by including an elastic pressurizing means connected to a stave wherein the means forces the stave to move only in an opposite direction to a roller axis direction against a shift of the pressurizing means. CONSTITUTION: The maximum force that ends 12, 13 of a web 11 can apply to flanges 14, 15 depends on and is limited by force caused by spring legs due to flexion resulted from the web 11 rolling at a helical angle. That is, a lateral position of the web 11 is determined by the flanges 14, 15, while the web 11 and staves 24, 26 interact with one another so that the staves 24, 26 support the web 11 without influencing the lateral position of the web 11. The web 11 sequentially determines positions of axial directions of the staves 24, 26 with respect to an axis 28 of a roller 10. This structure serves as an automatic controller for preventing the ends 12, 13 of the web 11 from being damaged by the flanges 14, 15 of the roller 10.
