IPC: H01M2/02
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the leak of the mix, which is filled in a can material, during the manufacturing process by providing one or more stripes having a specified width, which are not coated with carbon, in the axial direction of circumference of an inner surface of a metal positive electrode can material of an alkaline dry battery. SOLUTION: A positive electrode can material 1 made of metal is rotated, and while colloidal liquid carbon 3 is injected for coating to the inner surface of the positive electrode can material from a gun nozzle 2, and dried so as to form a carbon film. At this stage, opening and closing of the nozzle 2 is controlled so that the time for jetting the carbon 3 from the nozzle 2 is set shorter than the time for rotating the can material 1 once, and a part H, which is not formed with a film, is thereby provided. The part H, which is formed with at least one or more stripes having a width at 1-2mm in the axial direction, generates the friction resistance between the can material 1 and the previously formed mix so as to prevent the generation of positional displacement due to a loose-out of the mix during the manufacturing process.  Consequently, correction of positional displacement is unnecessary, and lowering of productivity is prevented, and conductivity between the can material and the mix is improved.

Title: Steering system for vehicle
Inventor: OMURA HIROSHI
IPC: B62D101/00
Filed: 1992-12-16
Abstract: PURPOSE:To heighten steering stability at the time of a TCS setting switch being in the off state by providing a rear wheel steering angle correcting means for correcting the steering characteristic of rear wheels to front wheels in the in-phase direction at the off time of the manual switch for setting a traction system to an operating mode. CONSTITUTION:In the case of a TCS setting switch 39 being turned off, a TCS controller 34 is not operated, so that a road surface mu signal is not supplied to a controller 29. The road surface mu is therefore unknown. In the off state of the TCS setting switch 39, the probability of traveling on a normal high muroad is high, but the possibility of traveling on a low mu road is not null. In view of this, the target rear wheel steering angle thetaR in this case is set in such a way that the initial turning round performance in the case of the low muroad is low to heighten steering stability, and the lowering of steering stability in the case of the high mu road is prevented by not increase-correcting an in-phase gain.
