Abstract:
A luminaire of an embodiment includes an apparatus body, a light source unit, and a cover member. The light source unit is disposed in the apparatus body and including a light-emitting element as a light source. The cover member has translucency and diffusing properties, is formed so as to project from a front side edge portion of the apparatus body, includes a side wall extending along the edge portion and formed upright within a range of inner angle from 60° to 90° with reference to a horizontal plane at least partly along the edge portion, and covers the light source unit so as to leave a substantially center portion of the apparatus body as an uncovered portion.
Abstract:
A protruding portion of a rotational speed detecting unit which is attached to a stationary side seal unit which is fixed to a stationary member which protruding portion protrudes axially and outer circumferentially of the stationary member is formed into a shape which has projecting portions in an axial direction, whereby the protrusion to the axial direction is reduced without reducing a bending strength in the axial direction, as a result of which the rotational speed detecting unit is miniaturized in the axial direction. Further, reinforcement members are embedded in an interior of the protruding portion, whereby the rotational speed detecting unit is miniaturized further in the axial direction.
Abstract:
An electromagnetic wave shielding sheet includes a transparent substrate 11 and a metal layer 15 provided on one surface of the transparent substrate 11 through an adhesive layer 13. The metal layer 15 includes a mesh part 103 and a frame part 101 surrounding the mesh part 103. The frame part 101 includes at least one transparent part 105 that is a metal-layer-free area. Preferably, the transparent part 105 includes a metallic portion 105a in a geometric pattern. Light transmitted by or reflected from the transparent part 105 is detected, thereby the transparent part 105 can be used as a register mark for detecting the position of the mesh part 103.
Abstract:
There is provided an electromagnetic wave shielding sheet which can effectively prevent an adhesive layer from being colored at the time of etching. The electromagnetic wave shielding sheet comprises a laminate of at least a transparent substrate film, an adhesive layer, and an electromagnetic wave shielding layer. The electromagnetic wave shielding layer is formed of a mesh metal foil with densely arranged openings and being transparent. The adhesive layer is substantially colorless and transparent.
Abstract:
A rolling bearing assembly for a wheel includes a cylindrical fixed bearing ring fixed to a vehicle body side, a rotary bearing ring rotatably inserted to inside of the fixed bearing ring, and plural rows of rolling elements rollably arranged between the bearing rings. An annular sensor housing is attached to an inboard side end portion of the fixed bearing ring and includes a plurality of displacement sensors for detecting gaps between the displacement sensors and outer peripheral surfaces of inboard side end portions of the rotary bearing ring in a circumferential direction. Further, an inboard side end portion of the sensor housing is sealed by an inner side seal device.
Abstract:
A metal film 21 is laminated directly to or by means of an adhesive 13 to a transparent base sheet 11. A mesh metal film including lines defining apertures is formed by coating the metal film 21 with a mesh resist layer 109a patterned in a mesh, etching the metal film 21 through the mesh resist layer 109a, and removing the mesh resist layer 109a. The front surfaces and side surfaces of the lines of the mesh metal film are coated with a black coating layer 23.
Abstract:
A luminaire includes a light-emitting unit, a main body frame, a support frame, and a lighting unit. The light-emitting unit mounts light-emitting elements. The main body frame supports the light-emitting unit, and is formed rectangular having a hook-shaped engaging piece on one side. The support frame is formed rectangular surrounding the outer periphery of the main body frame, and has a groove-shaped receiving place to engage with the engaging piece of the main body frame, on one internal side. The lighting unit turns on the light-emitting elements.
Abstract:
A magnetized pulsar ring of the invention is a pulsar ring fixed to an outer peripheral surface of a supporting member and including a ring body in which a number of magnetic poles are at predetermined intervals in a peripheral direction. The ring body 11a is formed of a plastic magnet, and has a cushion member made of an elastic body that is interposed between the ring body and the outer peripheral surface.
Abstract:
An electromagnetic shielding sheet of the present invention includes a transparent base sheet and a metal layer attached to one surface of the transparent base sheet. The metal layer has a mesh part, a peripheral mesh part surrounding the mesh part, and a grounding frame surrounding the peripheral mesh part. A width of lines forming meshes in the peripheral mesh part gradually increases from the mesh part toward the grounding frame. The lines of the electromagnetic shielding sheet are scarcely bent or broken in all processes including fabricating and assembling processes, and the electromagnetic shielding sheet is excellent in handling ease.
