Abstract: A linear motion guide apparatus in which a guide rail can be readily provided with a meshing portion that meshes with a gear is provided. The linear motion guide apparatus includes: two guide rails that are movable relative to each other in a longitudinal direction thereof via at least one rolling element; and a cage configured to hold the rolling element and rotatably hold a gear engaging with a meshing portion provided to at least one of the two guide rails. The meshing portion includes a plurality of circular holes arranged in the longitudinal direction on the guide rail. Each of the circular holes has a wall surface formed in a cylindrical shape.

Abstract: A memory system for speeding up a read operation in the memory system includes a first pillar, a first string including a first transistor and a first memory cell, a second string including a second transistor and a second memory cell, a first bit line, a first gate line, a first word line, a second gate line, a second word line and a control circuit. When the control circuit executes a read operation with respect to the first memory cell, the control circuit is configured to apply a read voltage to the first word line, apply a voltage turning off the second memory cell regardless of an electric charge stored in the second memory cell to the second word line, apply a voltage turning on the first transistor to the first gate line, and apply a voltage turning on the second transistor to the second gate line.

Abstract: The motion guide device includes a track member in which a rolling member rolling surface is formed along a longitudinal direction thereof, a movable member which is reciprocally movable with a number of rolling members being interposed therebetween and which is provided with a loaded rolling member rolling surface constituting a loaded rolling member rolling path opposing to the rolling member rolling surface and a rolling member return path, and a lid member provided with a pair of direction changing paths for connecting both end portions of the loaded rolling member rolling path and the rolling member return path to thereby constitute an endless circulation path. Flange portions are formed to both end portions of the movable member in the reciprocally moving direction by means of insert molding, and the flange portions are provided with fitting portions formed to end portion sides of the movable member.

Abstract: A motion guide device includes a plurality of rolling element guide members provided along the entire length of a rolling element rolling surface so as to guide the unloaded side of a plurality of rolling elements that perform a rolling movement under load between the rolling element rolling surface and a loaded rolling element rolling surface. The rolling element guide member includes a beam member an outer member including a rolling element guide surface for guiding the unloaded side of the rolling elements, and the beam member and the outer member are insert-molded. Such a structure provides the motion guide device including the rolling element guide member that enables low cost manufacturing of a complex shape and capability of secure installation and guidance of the rolling elements with no deflection and can be adapted for use in various types by optionally selecting a connecting means.
