Title: Abrasion reduction method for resin gear and resin gear molding whose abrasion is reduced
Inventor: UEDA TAKANORI
IPC: F16H55/08
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To reduce abrasion by adopting an involute gear or a similar one in which a leading end of each tooth is cut by a specified rate in a diameter direction of a pitch circle for suppressing meshing at the teeth leading in the case that, in the paired resin gears, less teeth number is specified. SOLUTION: In a pair of gears to be meshed with each other, the gear with less number of teeth has 30 or less. In such a case, the profile is an involute tooth profile or similar one in which a leading end of each tooth is cut 40 micrometers/module or more in a diameter direction of a pitch circle. As properly balanced gear material, polyacetal resin, polybutylene terephthalate resin having high compression fatigue resistance, or resin compound thereof is preferable. The gear is used for one or both of the meshed gears. With such a setup, the gears are not meshed with each other at the time of starting and finishing of the meshing with the maximum absolute value of sliding speed. Abrasion is thus reduced.

Title: Platform in skiing ground
Inventor: SUGIE HISAKAZU
IPC: B61B11/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To enable a skier to get on and off a carrier smoothly by forming a platform of an endless belt moving in the same direction as the direction of the advancing carrier and varying the speed of the endless belt with an accelerating/decelerating means connectivity disposed for the endless belt in a predetermined length region of the endless belt. SOLUTION: In a platform A on the side of the foot of a mountain, a skiier 7 stands by at a stand-by position. When a carrier 5 passes by a predetermined position, the skiier 7 transfers to the proximal end side of the front half part 1A. The front half part 1A is sequentially accelerated not to excead the speed of the carrier 5. While the skiier 7 transfers to the front half part 1A, the carrier 5 advancing with the fixed speed approaches the skiier 7. When the skiier 7 transfers to the rear half part 1a, the rear half part 1a transfers with the fixed speed slower than the speed of the carrier 5. Thus, in the rear half part 1a, the carrier 5 overtakes the skiier 7. Then, since a difference between the speed of the skiier 7 and the speed of the carrier 5 is small, the skiier 7 can smoothly transfer to the carrier 5 without impacts.

Title: Method for refining molten pig iron
Inventor: SAWADA IKUO
IPC: C21C1/04
Filed: 1985-10-01
Abstract: PURPOSE:To inhibit foaming and to remove Si and Mn from molten pig iron efficiently by changing the depth of immersion of a lance for injecting a solid oxide into the molten pig iron together with a carrier gas in the direction of depth in accordance with the concn. of Si in the molten pig iron. CONSTITUTION:When a solid oxide such as iron oxide is injected into molten pig iron together with a carrier gas from a lance, the depth of immersion of the lance is changed so that it is increased in the direction of depth from the beginning of the operation toward the end in accordance with the gradually decreasing concn. of Si in the molten pig iron. Si and Mn removing reactions are allowed to proceed simultaneously and the efficiency of the refining agent is enhanced, so the operation time is shortened and the amount of the refining agent used is reduced. Since the foaming of top slag is inhibited during the operation, the operation can be stabilized.
