Abstract: A mirror device includes a mirror including a main body portion having a reflection surface that reflects display light, and a rotating shaft protruding from a first side wall of the main body portion, and a driving member that includes a motor including an output shaft arranged parallel to the rotating shaft, and neighboring the rotating shaft in a direction orthogonal to a rotation axis line of the rotating shaft, a first gear portion coupled to the output shaft, and a second gear portion engaged with the first gear portion, and coupled to the rotating shaft, and rotates the mirror by transmitting rotation of the output shaft of the motor to the rotating shaft via the first gear portion and the second gear portion.

Abstract: A vehicle display device includes a housing including an opening, an image display device that outputs display light of an image, and a mirror that includes a main body including a reflective surface that reflects the display light toward the opening and is rotatable around a rotation axis. The mirror includes a first and a second ribs that extend along a first direction, and face each other in a second direction. The first rib is formed as a rib closest to a side of the upper end on the back surface, the second rib is formed as a rib closest to a side of the lower end on the back surface, and a central region between the first and the second ribs on the back surface is formed as a flat curved surface, at least a part of which extends from the first rib to the second rib.

Abstract: A degassing apparatus capable of preventing cross-contamination is provided. A degassing apparatus 1 includes degassing modules 10, 20, and 30 each having a tube unit 12 that is a gas permeable membrane separating a fluid circulation space S1 and a reduced-pressure space S2 from each other, vacuum piping 40 communicatively connected to the reduced-pressure spaces S2, a discharge device 50 that discharges gas in the reduced-pressure spaces S2 through the vacuum piping 40, atmospheric release piping 60 communicatively connected to the reduced-pressure spaces S2, an atmospheric release valve 70 capable of introducing atmosphere into the reduced-pressure spaces S2 through the atmospheric release piping 60, and a control unit 80 that controls the operation of the discharge device 50 and the atmospheric release valve 70.

Abstract: A heavy duty tire comprising: a shoulder rib (A1) (shoulder rib (A5)) which is provided to a tread shoulder unit; a second rib (A2) (second rib (A4)) which is adjacent to the shoulder rib (A1) with a circumferential groove (110) (circumferential groove (116)) interposed therebetween and is provided further toward the tire equator side than the shoulder rib (A1); and an uneven wear absorbing rib (B1) (uneven wear absorbing rib (B2)) provided within the circumferential groove (110) and located further toward the inside in the tire radial direction than the tread surfaces of the shoulder rib (A1) and of the second rib (A2). Circumferential narrow grooves (10, 12) having a smaller width than the circumferential grooves (110, 116) are formed in the second ribs (A2, A4).

Abstract: A pneumatic tire 10a including in a tread at least two circumferential major grooves 20a, 21a, 22a, and 23a extending in a tire circumferential direction and a rib-shaped land section formed, the pneumatic tire including: lug grooves 30a, 31a, 32a, and 33a extending in a tire width direction, each of which includes an end closed by the lib-shaped land section and the other end open to one of the circumferential major grooves (21a, 22a), the open ends being arranged in a staggered fashion in the tire circumferential direction; and first sipes which include a sipe 40a extending in the tire width direction and a sipe 41a extending in the tire circumferential direction and connect the lug grooves arranged in the staggered fashion.

Abstract: To provide a pneumatic tire excellent in both traction performance and braking performance on ice and snow road surfaces. A large number of blocks (26) of same-shape partitioned by main grooves and lug grooves are formed on a tread part (16). The tread part (16) comprises a center block row (32) and second block rows (34L) and (34R). Each of the blocks (26) comprises a plurality of sipes (30). Also, Gt=S/(Sa+Sb×0.6), and Gu=S/(Ds×L+Sb×0.6) are calculated for the each block where the area of the outer wall of the block (26) is (Sa) and the overall area of the sipes (30) on the block (26) is (Sb). Also, when the total sum (Gt) which is the total sum of (Gt) in three block rows and the total sum (Gu) which is the total sum of (Gu) in three block rows are calculated, the requirements 0.95?Total Sum Gt?1.05 and 1.30?Total Sum Gu?1.60 are satisfied.

Abstract: A metallic paint film of this invention comprises a base paint film containing by from 1 to 20 weight % of a novel pigment, which comprises a ceramic scaly substrate, an inorganic compound coating film formed on all the surfaces of ceramic scaly substrate, and a plurality of metal dots formed on the surfaces of inorganic compound coating film and occupying from 0.05 to 95% of the total surface area of the inorganic compound coating film. When an automobile body or the like is painted with the metallic paint film, it gives not only a simple metallic feeling but also a pearly gloss effect. In addition, the metallic paint film improves the three-dimensional effect of the automobile body or the like.
