  • Patent number: 9366827
    Abstract: An optical connector assembly and an optical connector adapter with a shutter each provide better heat radiation performance by blocking light outputted from a first optical fiber held by a first optical connector plug with a shutter thereby controlling temperature of an adapter body of the optical connector adapter not to exceed a prescribed level even when light having optical high power is outputted from the first optical fiber for about 15 minutes. An countermeasure against the light having optical high power is provided in a side wall of one of first and second receiving holes to be irradiated with the light outputted from the first optical fiber toward the second receiving hole and reflected thereafter by the shutter plate disposed in one of the first and second receiving holes.

  • Patent number: 9267591
    Abstract: Among first and second stators of a torque converter supported on a fixed part by a one-way clutch corresponding to the stators, the number of second stator blades of the second stator on the downstream side in the direction of flow of oils larger than the number of first blades of the first stator on the upstream side, and the maximum value t2 for blade thickness of the second stator blade is smaller than the minimum value t1 for blade thickness of the first stator blade. Therefore, it is possible to ensure that there is a sufficient gap (?) between a trailing edge of the first stator blade and a leading of the second stator blade, thus preventing the flow of oil from being stopped by the gap (?), and it is possible to align effectively the flow of oil by means of the second stator blades.

  • Publication number: 20150377319
    Abstract: A damper with a torque limiter is provided in which a torque limiter is formed from an annular limiter housing formed on a mass ring, a friction plate frictionally engaging with the limiter housing a pressure-applying plate that frictionally engages with the friction plate and that is linked to the mass ring, and a limiter spring urging the pressure-applying plate toward the friction plate side, a spring holder is formed from a pair of first and second holder plates that oppose each other to define a damper housing and that are joined to each other by a rivet, and the friction plate is formed integrally with the second holder plate. Thus, a rivet providing a link between a pair of holder plates forming a spring holder does not carry the burden of torque transmission, enabling the diameter of the rivet to be smaller and thereby reducing weight and cost.

  • Patent number: 8984905
    Abstract: A desiccant air conditioner has a high energy efficiency due to the absence of excessive heat loss due to ventilation. In order to meet this requirement, the desiccant air conditioner is equipped with a honeycomb rotor wash-coated with agents having capabilities of absorptions of humidity, carbon dioxide and nitrogen, and this honeycomb rotor is divided into at least an absorption zone and a desorption zone. The air in a room is, after being passed through the absorption zone, fed back to the room, and the air which is passed through the desorption zone is exhausted into outside of the room. In this way, carbon dioxide and nitrogen in a room, the latter quantity being corresponded to that of the consumed oxygen in the room, are exhausted into outside of the room, allowing to exhaust carbon dioxide and at the same time to keep the oxygen density to within an allowed limit without the need of excessive ventilation.
