Abstract: A distance between a rotation center of an input member and a contact portion between an input side engaging portion and an input side engaged portion in a second direction is set to be shorter than a distance between a rotation center of an output member and a contact portion between an output side engaging portion and an output side engaged portion in the second direction. In a locked or semi-locked state, a contact portion between the output side engaging portion and the output side engaged portion is located on the side closer to the rotation center of the output member in a first direction in relation to a virtual line connecting the rotation center of the output member and a contact portion between one pressing surface of the pair of pressing surfaces and the pressed surface.

Abstract: Separate structural units for an inner gear and a housing of a planetary gear device include an inner gear with a first raised portion formed on the outer peripheral surface of the inner gear, where the first raised portion extends towards in a direction that is inclined with respect to the axial direction of the inner gear. A housing includes a second raised portion formed on an inner peripheral surface, where the second raised portion extends in a direction that is inclined in respect to the axial direction. The housing contains the inner gear such that there is a gap formed between the inner peripheral surface of the housing and the outer peripheral surface of the inner gear. Movement of the inner gear within the interior of the housing is limited through linear contact of the first raised portion and the second raised portion.

Abstract: In a predetermined first state, a distance (D1) in a second direction between a contact portion (Pin) between a input-side engaging part (9) and an input-side engaging part (17) and a rotation center (O) is larger than a distance (D2) in the second direction between a contact portion (Pout) between an output-side engaging part (12) and an output-side engaged part (14) and the rotation center (O). In a locked state or a semi-locked state, a contact portion (C1) between the output-side engaging part (12) and the output-side engaged part (14) is located closer to the rotation center (O) of the output member (4) in a first direction than an imaginary straight line (L) connecting a contact portion (C2) between one pressing surface (13) of the pair of pressing surfaces (13) and a pressed surface (6) to the rotation center (O) of the output member (4).

Abstract: In the centrifugal pendulum damper, a plurality of pendulums are swingably supported on a rotating body. The pendulum includes a swinging shaft serving as the swing center and a rolling shaft including a rolling surface on the outer periphery thereof. The rotating body includes a plurality of pendulum support portions, and the pendulum support portion includes a swinging shaft guide portion that guides the swinging shaft in a radial direction of the rotating body, and a rolling shaft guide portion that is in rolling-contact with the rolling surface of the rolling shaft to cause the pendulum to swing around the swing axis.

Abstract: The present invention provides a method for producing an yeast having an increased cellulose hydrolysis ability. The method includes the step of introducing increased integration copy numbers of both a gene for an enzyme capable of hydrolyzing crystalline cellulose and a gene for an enzyme capable of hydrolyzing noncrystalline cellulose into a noncellulolytic yeast to give a transformed yeast. The yeast having an increased cellulose hydrolysis ability can be suitably used for ethanol production from cellulose-based materials.

The present invention also provides a method for producing a fermentation substrate for ethanol production by a yeast, including: subjecting a cellulose material to a hot-water treatment and an ammonia treatment to obtain a fermentation substrate. Thus obtained fermentation substrate can enhance the ethanol production by yeast.
