Title: Pneumatic tire
Inventor: KOISHI MASATAKA
IPC: B60C9/18
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire which enables the improvement in durability, the simplification of the manufacturing process and weight reduction. SOLUTION: In this pneumatic tire, a belt layer 5 made up of at least one layer of reinforcing sheet is arranged outside a carcass layer 2 in a tread part 4, so that the tensile modulus of elasticity per unit width of the belt layer 5 becomes greater than 500 kgf/mm. In this case, the belt layer 5 may be of such construction as a plural layers of reinforcing sheets are layered with a rubber layer between. When a plural layers of reinforcing sheets are layered with a rubber layer between, the balance between the ground-touched-surface's outward bending rigidity and the tensile rigidity in the circumferential direction of the tire becomes adequate, the ground touching characteristics are enhanced, and the maneuverability of the tire such as the cornering force is improved.  The reinforcing sheet can be obtained by forming a thermoplastic resin or a thermoplastic elastomer into a film-like shape.

Inventor: MATSUSHITA TSUYAKO
IPC: G03B7/08
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To obtain a camera system provided with a colorimetric function capable of appropriately using a colorimetric method intended by a photographer by measuring color information by appropriately using a reflector reflecting light from field and making it incident on a photometry part or a diffusing plate diffusing the light from the field and making it incident on the photometry part. SOLUTION: By using the standard white reflector 41, the field light from a light source is reflected to perform colorimetry. By attaching the milky-white diffusing plate 42 to the front surface of a camera body 51, the light from the light source is made incident so as to perform the colorimetry. Furthermore, by attaching the milky-white diffusing plate 42 to the front surface of an interchangeable lens 52, the light from the light source is made incident so as to perform the colorimetry. Thus, the colorimetric method intended by the photogapher is easily executed by appropriately using the reflector 41 or the diffusing plate 42. Therefore, when a subject is separated from a photographing position, the photographer need not go to the place of the subject, so that operability is improved.  The color information with which the color of a lens is tinged is obtained, so that the behavior range of the photographer is extended further.
