A highly durable tread pattern of a rib type pneumatic tire using two grooves for heavy vehicles is disclosed. The tread is provided with a pair of zigzag grooves extending circumferentially of the tread and dividing the tread into a center rib and a pair of side ribs. The center rib is provided with a plurality of sipe grooves arranged in a row and substantially equally spaced on the circumference of the tread by a pitch corresponding to a pitch between the zigzag tread grooves. The center rib and the pair of side ribs do not interrupt their circumferential continuity. Each of the sipe grooves is composed of a circumferentially extending section inclined at an acute angle of smaller than 45.degree. with respect to the circumferential direction and a widthwisely extending section inclined at an angle of at least 45.degree. with respect to the circumferential direction. These sections are formed into hook-shaped, bracket-shaped or curve-shaped formation or a combination of these formations.

Configuration of a hinge for avoiding likely collection of water provides a connector to prevent difficulty of opening or closing a cover by freezing of the hinge. A connector mounted in an electric vehicle and connected with a connector of a charging cable is provided with a housing, a cover rotatively pivoted about the housing so as to open or close the cover, and a shaft. The cover is provided with a pair of cover side mounting plates including a shaft hole passing the shaft therethrough, and the housing is provided with a pair of housing side mounting plates including a shaft hole passing a shaft therethrough, and positioning the pair of cover side mounting plates therebetween. The pair of cover side mounting plates is provided with a boss cylindrically upstanding from each of faces opposite to the pair of housing side mounting plates, and passing the shaft therethrough.

An optical sheet includes a sheet-like body portion, and unit prisms arranged on one surface of the body portion. Each unit prism extends linearly in a direction intersecting the arrangement direction. Each unit prism, when viewed in a direction parallel to the arrangement direction of the unit prisms, has an uneven polygonal-line-shaped contour and, with reference to raised portions defined by the polygonal-line-shaped contour of each unit prism, the distance between a top of each raised portion, a farthest point from the body portion in the raised portion, and the body portion in the normal direction of the body portion is not constant. The optical sheet can prevent significant problems when it is superimposed on another member.

Provided is a connector in which a cover is readily closed when ice is induced between a pair of shaft attachment plates by such snowfall. A connector mounted in an electric vehicle and connected to a connector of a charge cable is provided with a housing, a cover rotatably pivoted by the housing and covering an opening of the housing, a latch, and shafts. The cover is provided with a pair of shaft attachment plates and a rib arranged between the pair of shaft attachment plates. The rib extends in a direction perpendicular to a direction of the pair of shaft attachment plates being opposed to each other, and formed such that its tip is peaked. In the connector, even when ice is induced rotation of the cover in closing direction allows the ice to be broken by the rib so as to readily close the cover.

The present invention relates to a low expansion glass substrate which serves as a substrate of a reflective mask used in a lithography step of semiconductor production steps, wherein two side surfaces positioned to face each other among side surfaces formed along a periphery of the low expansion glass substrate, each have a flatness of 25 μm or less.
摘要:
A vibration isolator having an inner passage of a communication tube that communicates the negative pressure chamber with the valve chamber. A pipe connection part and a supply/discharge pipe communicate the valve chamber with the supply/discharge port of a switching valve on the outside of the vibration isolator. The switching valve selectively communicates the supply/discharge port to either an intake manifold as the negative pressure supply source, or an atmosphere space. The negative pressure chamber communicates with the valve chamber through the communication tube on the inner peripheral side of the outer cylinder member. Thus, either of a negative pressure and an atmospheric pressure, which is same as a pressure in the valve chamber, can be supplied into the negative pressure chamber, by supplying either of the negative pressure and the atmospheric pressure into the valve chamber through the supply/discharge pipe and the pipe connection part.
