IPC: F16H7/12
Filed: 1990-04-05
Abstract: PURPOSE:To prevent lubricating oil from being agitated by a tension pulley to raise its temperature by arranging the tension pulley at a position far away from the lubricating oil level. CONSTITUTION:A pair of rotary shafts 7, 8 are horizontally supported in parallel in a case 2, and a cog-belt 13 is laid over cog-pulleys 10, 12 fixed to both the rotary shafts 7, 8.

IPC: G11B5/17
Filed: 1989-04-07
Abstract: PURPOSE:To improve an electromagnetic conversion characteristic by setting the ratio of a winding applied to a core where a groove for an internal winding is not formed, larger than the winding applied to the core where the groove for the internal winding is formed. CONSTITUTION:To oxide magnetic material cores 1 and 2, grooves 1a and 2a for external winding are formed, respectively and on the other hand, a groove 1b for internal winding is formed only to the core 1. The ratio of the winding wound at the core 2 side, where the groove 1b is not formed, is made larger than the winding wound at the core 1 side where the groove 1b is formed. Thus, since the groove 1b is not provided on the core 2 with the large ratio of the winding, the degradation of a magnetic characteristic by a shape effect is made small, and the electromagnetic conversion characteristic is improved.
