Title: Rubber crawler
Inventor: NISHIMURA NAOKI
IPC: B62D55/253
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a rubber crawler for arranging a bias cord for suppressing the generation of twisting and improving lateral rigidity without causing weight increase or winding rigidity to a roller. SOLUTION: In an endless belt-like rubber crawler 1 embedded with a main cord 4 having a cord angle in a peripheral direction, a single layer bias cord, constituted by combining plural cords 5 and 6 having a reverse cord angle with each other in a same plane, is laminated on the cord 4. In a bias cord, twist shearing force between plural cords for constituting the bias cord is effectively canceled, while having light weight and simple structure being sufficient as one layer in the same plane, to improve straightly-advancing travel performance, and moreover since the cords 5 and 6 have a single layer, weight increase of the whole roller 1 is not caused and winding rigidity to driving and driven rollers is low, to eliminate the increase of travel resistance.

Filed: 1990-07-06
Abstract: PURPOSE:To easily mold a long pipe-shape member suitable for such a case that an attachment is mounted on said member at the time of use by a method wherein an embedding metal jig and a laminate are integrally received in a mold and heated along with the mold to mold the laminate. CONSTITUTION:For example, a long square pipe-shape embedding metal jig 1 is formed from a material having the large coefficient of thermal expansion such as aluminum and an FRP material 2a such as a prepreg is wound around the outer peripheral surface of the embedding metal jig 1 to form a laminate 2. Next, the integrated body of the embedding metal jig and the laminate 2 is received in female molds 3 composed of a material having the small coefficient of thermal expansion such as steel in such a state that the outer diameter dimension thereof is held and subsequently heated along with the molds 3. By this heating, the resin of the laminate 2 is softened and, at the same time, the embedding metal jig 1 is thermally expanded. Therefore, the internal pressure due to the embedding metal jig 1 is applied to the laminate 2 in such a state that the outer diameter dimension of the laminate 2 is secured by the molds and, therefore, the laminate 2 is molded and cured with high accuracy. Next, a pipe-shape part is taken out of the molds 3 as a molded product.

Abstract: PURPOSE:To determine refractive index of soft X-ray transmissive material highly accurately by making a pattern of a material to be measured on a soft X-ray transmissive thin film, transferring the pattern to a substrate to be exposed located closely to the thin film, determining the thickness of pattern having most conspicuous profile, and then calculating refractive index based on the thickness and the wavelength of irradiating light. CONSTITUTION:A soft X-ray transmissive thin film 2 is stretched over a substrate 1 and a first pattern 5 of a soft X-ray transmissive material is formed thereon in order to measure the refractive index. A substrate 7 to be exposed applied with resist 6 is disposed closely to the pattern 5 and irradiated with soft X-ray 8 of wavelength lambdathrough the pattern 5 in a vacuum or in helium gas of reduced pressure. Assuming the thickness of the pattern 5 is (t), refractive index thereof is (n), and refractive index of atmosphere is (n'), the soft X-ray 8 passed through the outside of the pattern 5 interferes with a soft X-ray 8 passed through the inside under a condition of 2(n'-n)t=lambda thus transferring conspicuous second pattern. When the pattern 5 is formed with different thicknesses and the thickness providing a most conspicuous second pattern is determined, refractive index can be determined according to a formula n=n'-lambda/2t.

Filed: 1983-09-30
Abstract: PURPOSE:To improve image disturbing characteristics by forming an input filter with plural filters changed over in response to the reception band and having different pass bands and attenuating an image frequency generated at the 2nd mixer circuit by respective filters. CONSTITUTION:An input signal from a terminal 1 passes through the input filter 9 and is inputted to the 1st mixer circuit 3. The signal is converted at the circuit 3 into the 1st IF frequency by using a signal from the 1st local oscillator 4 and the result enters the 2nd mixer circuit 6 through a BPF 10. The signal is converted into the 2nd IF frequency at the circuit 6 by using a signal from the 2nd local oscillator 7. The BPF10 suppresses the leakage of the signal of the oscillator 4 to the circuit 6 and the leakage of the signal of the oscillator 7 to the circuit 3, respectively. The filter 9 consists of filters 13-19 with fixed pass bands different in the reception band respectively and switching diodes 20-23, and when the diode of a desired reception band is conductive, the other diodes are nonconductive. The filters 13-19 suppress the image frequency of each reception band.
