Title: Mounting structure of part
Inventor: TAMURA SHOJI
IPC: B21D39/00
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To obtain a simple structure which has no backlash among parts and is surely mountable. SOLUTION: A cut groove 3 is arranged to the periphery of a fastening through hole 20. As a result, when a fastening pin 10 is fastened, part of the fastening pin 10 is bitten into the cut groove 3 of the periphery of the fastening through hole 20, even in the case there is a clearance S between the outer face of the fastening pin 10 and the inner face of the fastening through hole 20, generation of a backlash between a part to be mounted of a fastening pin 10 side and a mounting part of a fastening through hole 20 side is prevented, the part to be mounted and the mounting part is surely mounted without a backlash. Further, because the cut groove 3 only is arranged to the periphery of the fastening through hole, the structure is simple as compared one in which engaging pawls are protruded to the periphery of the fastening pin.

Abstract: PURPOSE:To obtain a switching action with high answerability and stability and without causing chattering by placing an end of a shaft such that it is opposed to a throttle lever and mounting the extended portion of a housing on a cylindrical body. CONSTITUTION:When a ring projection 9a of a pressure sensitive conductor 9 is pushed to a fixed contact 5 in a throttle switch 1, the resistance value of a conductor 9 becomes least, and when the top 3a of a shaft 3 is pushed in the direction of a sliding element 8 and against a compression spring 10, the sliding element 8 slides inside a guide cylinder 7 and a pushing force of the contact 5 of the projection 9a decreases, the value of resistance of the conductor 9 increases, and when the top 3a ranks with the end face of the extended portion 2b, the value of resistance becomes most. When this switch 1 is mounted to a carburetor, an shaft 21 is made to clockwise move and a throttle valve 22 circularly moves in the opening direction, a throttle lever 23 moves in the direction to segregate from the top 3a. Thereby, the resistance value of the conductor 9 decreases and reaches a prescribed one; thereupon, a current flows between lead wires 11a and 11b.

IPC: H01F1/055
Filed: 1981-12-23
Abstract: PURPOSE:To improve magnetic characteristics as a whole by a method wherein the friction force of formed powder can be reduced and formation density and orientation can be increased without increasing welding pressure and an orientation magnetic field, and furthermore, adverse influence is not given to the magnet characteristics. CONSTITUTION:In the manufacturing method of a rare earth permanent magnet by powder metallurgy processing forming and sintering alloy powder serving rare earth metal (including yttrium) and transition metal as a main component, oleic acid of 1.0% or less by wt is added to said preformed alloy powder. Residual magnetic flux density Br is provided with peak at the amount of oleic acid of 0.2-0.5% by wt. Meanwhile, maximum energy product (BH)max has peak at the mixed amount of the oleic acid of 0.05% by wt. Peak is decreased when percent by wt exceeds the above values. When wt exceeds 1%, the residual magnetic flux density Br and the maximum energy product (BH)max become worse compared with the case when no oleic acid is added. Formation density rapidly increases by adding a very small amount of oleic acid. The increasing rate is decreased at 0.05% or more by wt.
