Abstract: PURPOSE:To reduce side radiation noise without harming driving stability and the like by extending main layer and auxiliary cords, arranged slantly in a specific angle against the equatorial surface of a metal cord, in parallel with the equatorial surface in the area matching the inside of a belt layer and forming them by a shallow inclination and rough cord counting in the central area. CONSTITUTION:A belt layer 6 is formed of a main layer 7 and an auxiliary layer 8 which is superposition of layers 62 similar to the layer 61 of a metal cord arranged slantly in 10 deg. to 30 deg. against the equatorial surface O. The auxiliary layer 8 is composed of a central area C, whose width is 60% of the width W of the main layer 7, and a side area S whose width corresponds to 20% of the width W of the main layer 7, and the cord in the side area S is practically in parallel with the equatorial surface O while the cord in the central area C is inclined in a shallow angle of 0 deg. to 10 deg. against the equatorial surface, and formed by counting with relatively rough cord. Thus passing noise can be reduced without harming the driving stability.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a predicting method of the staying time of a steel slab in a heating furnace without aggregating energy efficiency, by which the staying time of the steel slab in the furnace needed to heating can accurately be predicted even if the steel slabs having different kinds of steels and different sizes are continuously heated. SOLUTION: In the case that there is a group to be preferentially subjected to heating treatment in classified groups, the temp. of the heating furnace in the heating conditions of this group is made to be a target temp. In the case that there is no such a preferential group in the classified groups, the lowest temp. of the heating furnace among all groups is made to be a target temp. and the target temp. of the heating furnace and a temporary feeding speed of the steel slab is decided from the target temp. of the heating furnace and the steel slab temp. in each group. The temporary feeding speed of the steel slab of the preferential group is decided as the feeding speed of the steel slab of each group, and the feeding pitch in the heating furnace is calculated from this feeding speed of the steel slab.

Abstract: PURPOSE: To provide an improved X-ray tube for a CT scanner. CONSTITUTION: A rotor 30 is rotatably fitted into a doughnut-shaped housing A, and a negative electrode C is fitted to the rotor 30 in proximity to a positive electrode B to form an X-ray tube. Electron beams emitted from the negative electrode C collide with the positive electrode B to create X-ray beams. The X-ray beams are received by a radiation intensity detector 160. A grid bias control circuit 100 selectively applies continuously adjustable bias to a grid 32 to adjust the intensity of the X-ray beams. A scintillation optical fiber 110 fitted close to a window 20 converts a small quantity of incident X-rays into light. Light conveyed through the scintillation optical fiber is converted into an electric signal indicating radiation intensity by a light-electricity transducer 118.

Abstract: PURPOSE:To detect the accurate speed and direction of a moving body with respect to the surface of the ground, by fixing an image pick-up part to the moving body and applying image processing to the obtained image signal. CONSTITUTION:An image pick-up part 1 is provided so as to match the focus thereof with the surface of the ground 6 and the obtained image signal is processed by an image processing part 2 to be displayed on an image display part 3.
