Title: Rubber crawler
Inventor: FURUTA MITSUO
IPC: B62D55/253
Filed: 1998-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent crack formation and to hinder a lug from being cut by forming the lateral width of a core metal embedded in a cross direction to the travel direction of a rubber crawler, almost the same as the lateral width of the rubber crawler. SOLUTION: A core metal 1 is embedded in rubber 2, and the lateral ends 1A of the core metal 1 are made almost the same as the lateral width direction of a rubber crawler so as to form a rubber part 2A with a thickness of about 2 mm. Steel cords are embedded outside of blade parts 1B of the core metal 1. Angular parts 1C are protruded from the inner peripheral surface of the rubber crawler, and rubber lugs are formed on the outer peripheral side. Recesses 1D are formed at the lateral ends 1A of the core metal 1. The rubber quantity is increased by the portion of these recesses 1D. Separation between the core metal 1 and the rubber 2 is therefore impeded. The width of the lug part 3 of the rubber crawler is markedly narrow in the rubber part 2A so as to be prevented from bending even in the case of running up on a protrusion on the road surface. A crack is not therefore formed.

Title: Measuring method for surface roughness
Inventor: NAGANUMA TAKESHI
IPC: G01B11/30
Filed: 1985-08-29
Abstract: PURPOSE:To easily measure surface roughness eliminating waveness by dividing a cross-sectional curve of an object to be measured into the sections shorter than the waveness and measuring the roughness from the cross-sectional curve rearranging the average line of each section in a straight line. CONSTITUTION:A computer is interlocked with a conventional surface roughness measuring instrument and information on the cross-sectional curve 7 measured with a roughness gage is stored therein. This is divided setting the section shorter than the wavelength of the waveness, for instance, 0.5mm in the computer. The average line 9 making the sum of squares of a deviation to the cross-sectional curve 7 on this section minimum is calculated. Then, the average line 9 is rearranged to make the straight line and the surface roughness on the cross-sectional curve is measured by a well-known method. As a result, the surface roughness without being influenced by the waveness is easily calculated and the measurement with good correlation with a gloss result with visual observation can be performed.

Abstract: PURPOSE:To enable to prolong the service life of a seal, by a method wherein when fitting a new seal after a seal sliding surface is abraded, a seal lip part of the new seal is slidden against a bush end surface part different from the sliding part which has been abraded, in a track shoe of a construction machine. CONSTITUTION:When an abraded groove 1b is generated at the sliding surface between the seal lip part 5a of the seal 5 and the bush end surface 1a, the assembly is disassembled, the seal 5 is removed, and a new seal 9 is fitted into a counterbore part 4a by combining it with a load ring 6 previously used. In this case, the shape of the seal 9 is so determined that the seal lip part 9a thereof is placed on the side of the inside diameter 1c instead of being placed at the groove 1b abraded in operation before reversing the bush. Accordingly an oil can be sealed in after reversing the bush, and the service life of the seal after the reversion of the bush can be largely prolonged.

Title: Production of color filter
Inventor: YAMAMOTO KATSUMI
IPC: G02B5/20
Filed: 1984-09-11
Abstract: PURPOSE:To prevent the color mixing of adjacent color filters and to improve the accuracy of the patterns by interposing a dyeing preventive agent to a thin dyeable film to reform the film to have non-dyeability and irradiating UV rays to the desired part to make dyeable said part. CONSTITUTION:The thin dyeable film 2 which is reformed to have the non- dyeability by the dyeing preventive agent incorporated therein is formed on a substrate 1 and a quartz mask 3 is brought into tight contact therewith. The UV rays 4 are selectively irradiated only to the point desired to be dyed to the 1st color. The dye preventive agent is decomposed in the irradiated part 2a by which said part is made into the dyeable region. If such substrate is immersed in a dyeing liquid, the part 2b where the dyeing preventive agent exists is not dyed and only the part 2a is dyed to form the filter layer 7a of the 1st color. A soln. of a dye fixing agent is thereafter brought into contact therewith to fix the dye of the layer 7a. The mask 3 is so placed thereto as to prevent the overlap of the layer 7a and the irradiated region and the UV rays are irradiated thereto to form the filter region of the 2nd color. Such stage is repeated until the required number of the colors of the filter layers is satisfied.
