摘要:
A rotation transmission device is provided which includes a two-way clutch and an electromagnetic clutch for engaging and disengaging the two-way clutch and which can be easily assembled without the need for a shim to prevent movements of the clutches. The two-way clutch (10) and the electromagnetic clutch (50) are mounted in a housing (3) including at one end a positioning arrangement (5). The two-way clutch (10) and the electromagnetic clutch (5) are biased by an elastic member (7) supported by the positioning arrangement (5) toward an anti-separation ring (8) provided on the inner periphery of the housing (3) at the other end thereof, and are thus prevented from moving.

A motor assembly includes an electric motor and a speed reducing mechanism. The speed reducing mechanism includes: a housing; an internal gear supported by the inner diameter surface of the housing; eccentric disks capable of rotating inside the internal gear when the rotating shaft of the electric motor rotates; an output shaft having at the axial end thereof a cage rotatably disposed between the internal gear and the eccentric disks, the cage being arranged coaxially with the rotation axis of the eccentric disks; and rolling elements retained by the cage and meshing with internal teeth of the internal gear, the number of the rolling elements being smaller than the number of the internal teeth. The eccentric disks are provided on the rotating shaft of the electric motor.

In an outer blade cutting wheel comprising an annular thin disc base of cemented carbide having an outer diameter of 80-200 mm, an inner diameter of 30-80 mm, and a thickness of 0.1-1.0 mm, and a blade section disposed on an outer periphery of the base, the blade section comprises diamond grains and/or CBN grains bound with a metal bond having a Young's modulus of 0.7-4.0×1011 Pa and has a thickness which is greater than the thickness of the base by at least 0.01 mm. The outer blade cutting wheel is capable of cutting a workpiece at a high accuracy and a reduced allowance, improves machining yields, and reduces machining costs.

Provided is an information processing apparatus including a specified region detection unit for detecting a specified region specified by a user within a screen during reproduction of a video, a region metadata setting unit for setting region metadata indicating a position and a range of the specified region for each video frame, and a section metadata setting unit for setting section metadata indicating a section corresponding to a video frame for which the region metadata has been set, for each video.
摘要:
A vehicle light can simultaneously form a light distribution pattern for a tail/stop lamp in one direction and another light distribution pattern for a side marker lamp in another direction without use of a dedicated light source(s). The vehicle light can include: a cover lens having a lens portion and a wraparound lens portion extending from the lens portion to the vehicle side face; a first LED light source configured to form first and second light distribution patterns; and a first reflector configured to reflect a first part of light from the first LED light source so as to form the second light distribution pattern. The first LED light source can be disposed so that a second part of the light from the first LED light source passes through the wraparound lens portion to form the first light distribution pattern. The first reflector can be disposed between the first LED light source and the wraparound lens portion so that the first reflector does not block the second part of the light.

A radial anisotropic sintered magnet formed into a cylindrical shape includes a portion oriented in directions tilted at an angle of 30° or more from radial directions, the portion being contained in the magnet at a volume ratio in a range of 2% or more and 50% or less, and a portion oriented in radial directions or in directions tilted at an angle less than 30° from radial directions, the portion being the rest of the total volume of the magnet. The radial anisotropic sintered magnet has excellent magnet characteristics without occurrence of cracks in the steps of sintering and cooling for aging, even if the magnet has a shape of a small ratio between an inner diameter and an outer diameter.
