Title: Power transmitting device for vehicle
Inventor: FUJII TAKAAKI
IPC: B60K20/00
Filed: 1992-10-20
Abstract: PURPOSE:To maintain good running feeling by providing a flat characteristics part at a part of shaft output characteristics to the rotational speed of a vehicle driving. CONSTITUTION:A flat characteristics part is formed at a part of shaft output characteristics to the rotational speed of a vehicle driving motor 18. Even if the frictional force of the belt 46 of a belt type non-stage transmission 53 changes with the passage of time or the like, a vehicle (rear wheel WR) is driven by a certain shaft output in the rotational speed of the vehicle driving motor 18 to the flat characteristics part. If the frictional force of the belt 46 of the belt type non-stage transmission 53 changes with the passage of time or the like, the rotational speed of the vehicle driving motor 18 whose rotational speed is changed steplessly changes, however, the vehicle (rear wheel WR) is driven by a certain shaft output in the rotational speed range of the vehicle driving motor 18 whose rotational speed is changed steplessly regardless of a change in rotational speed of the vehicle driving motor. It is thus possible to maintain good riding feeling during driving.

Title: Spark plug and method for manufacturing
Inventor: SAKURA AKIO
IPC: H01T13/39
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a spark plug which, a main attachment and a ground electrode thereof being integrated together, can effectively form a zinc galvanized layer on the portion except the leading end of the ground electrode. SOLUTION: A zinc galvanized layer 141 is uniformly formed on the outer surface of an attachment assembly in which the base end of the ground electrode 4 is installed on the main attachment 1. Then the zinc galvanized layer formed on the leading end of the electrode is removed by electrolytic separation and a metal chip with a high fusing point is welded on the surface of a base electrode material exposed by the separation, thereby forming an ignition section 32. In other words, since there is no need for masking not to form a galvanized layer on the leading end of a ground electrode, it is made possible to highly efficiently manufacture a spark plug 100 which forms the ignition section 32 on the ground electrode 4.  At the same time without the intervention of masking treatment after the separation of the galvanized layer, dirt and oil content are hard to attach and the purification of the surface of the base electrode material is facilitated by the separation treatment, resulting in an increase of welding intensity of the metal chip with a high fusing point and less occurrence of the problem of the separation of the ignition section.
