Title: Resin septic tank
Inventor: IMAI KATSUHIKO
IPC: B65D90/02
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce drop in strength after long-term use by containing a specific amount or more of ZrO2 and blending glass fiber excellent in resistance to alkali in a resin as a reinforcing material. SOLUTION: For the resin septic tank, a thermosetting resin selected among an epoxy resin, a polyester resin and a vinyl ester resin with glass fiber excellent in resistance to alkali as a reinforcing material is used. Thus even if an alkaline substance infiltrates into the resin, the glass fiber is difficult to corrode, and even if the tank is buried under the ground for a long time, rigid adhesion can be secured between interfaces of the glass fiber and the resin. In addition, drop in strength of the glass fiber itself is small, thereby keeping reinforcing effects of the glass fiber for a long time. ZrO2, which improves resistance to alkali of glass, is contained by 14 wt.% or more in a composition of the available glass fiber excellent in resistance to acid and alkali. Less than 14 wt.% might reduce its effects.

Title: Eccentric rocking type reduction gear
Inventor: MOCHIZUKI MASANORI
IPC: F16H1/32
Filed: 1991-12-05
Abstract: PURPOSE:To prevent the occurrence of a backlash by forming two eccentric rocking gears in the same shape as each other, peripherally displacing the one gear from the other gear on the ordinary gearing condition for an internal gear, and setting a displacement amount to a value equivalent to a backlash between a swing gear and the internal gear. CONSTITUTION:Eccentric swing gears 2a and 2b are both brought into internal contact with an internal gear 31 and geared therewith and the teeth of the one eccentric swing gear 2b are peripherally displaced based on the teeth of the other swing gear 2a on an ordinary gearing condition for the internal gear 31, and a displacement is set to a value equivalent to a backlash between the teeth of the eccentric swing gears 2a and 2b and the teeth of the internal gear 31. In a state that the eccentric swing gears 2a and 2a are both geared with the internal gear 31, a gearing margin equivalent to a backlash is produced at the teeth of the internal gear 31 but gearing prevented from the occurrence of a backlash is effected from a point of view wherein the eccentric swing gears 2a and 2b are integrally formed. This constitution prevents the occurrence of a rattle between the tooth phases of the eccentric swing gears 2a and 2b and that of the internal gear 31.
