Title: Frictional material
Inventor: MISAWA NORIO
IPC: C08J5/14
Filed: 1995-04-24
Abstract: PURPOSE: To suppress excessive wear of both a friction material and an opponent material under a severe condition used. CONSTITUTION: This friction material comprises a fiber base, a resin binder and a filler such as a solid lubricant, etc. Potassium titanate fiber or whisker containing an ion component is contained as the fiber base and 0.7-2.5vol.% based on the whole friction material of, antimony trisulfide is contained as the solid lubricant. Since the amount of antimony trisulfide blended is relatively small, excessive friction of an opponent material under severe use conditions (in the case of repeated braking at a velocity close to 200km/h, etc.) can be suppressed. The use of the potassium titanate fiber or whisker having especially high heat-resistant strength and containing an iron component can suppress excessive wear of the friction material itself to an excellent level. An abrasive agent having a small particle diameter is preferable.

Title: Parallax calculation device and method, and distance calculation device and method
Inventor: MIWA SACHIKO
IPC: G06T7/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To avoid occlusion that is caused when a certain object is hidden by another and to obtain the correct parallax information in a wide range in a stereographic image process. SOLUTION: The objects 221 and 222 , are photographed by plural cameras for production of images A to I. An arithmetic processing circuit calculates the SDS(sum of squared differences) between the standard pixel of the image A that is generated by a reference camera and the reference pixels of images B to I generated by other cameras. Then the arithmetic processing circuit properly divides the cameras into groups to calculate the SSSD(sum of SSDs) in each group and detects a reference pixel that secures the minimum value SSSDmin as a corresponding point of the corresponding reference pixel. Thus, the arithmetic processing circuit measures the parallax between the detected corresponding point and the reference pixel and then measures the distances among the points of both objects 221 and 222 based on a trigonometrical survey theory to analyze the shape of each object.
