Abstract: A memory controller according to the embodiment includes a front-end unit that issues an invalidation command in response to a command from outside of the memory controller, the command including a logical address, an address translation unit that stores a correspondence relationship between the logical and a physical address, an invalidation command processing unit that, when the invalidation command is received, registers the logical address associated with the invalidation command as an invalidation registration region in an invalidation registration unit and issues a notification to the front-end unit, and an internal processing unit that dissolves a correspondence relationship between the logical address registered in the invalidation registration unit and the physical address in the address translation unit in a predetermined order by referencing the logical address registered in the invalidation registration unit.

Abstract: According to one embodiment, a video apparatus comprises a program recorder configured to record programs divided into scenes, a program information recorder configured to record program information includes scene information of each scene of the recorded program, a module configured to examine relevance of scenes among the recorded programs based on the recorded scene information in order to set priorities to relevant scenes among the recorded programs, an instruction module configured to instruct playback of any one of the recorded programs, and a playback module configured to play back a scene with a highest priority among scenes relevant to a certain scene of a program of which playback is instructed.

Abstract: A filtering element for air filter is formed by joining an upstream layer arranged upstream in flow direction of air integrally with a downstream layer located downstream in the flow direction of the air. The upstream layer collects dust from the air and the downstream layer supports the upstream layer. The upstream layer is formed through press forming of a nonwoven fabric formed of fibers having an average diameter of 0.5 ?m to 2.5 ?m. The thickness of the upstream layer is set to 0.005 mm to 0.1 mm, and the porosity of the upstream layer is set to 78% to 92%. The downstream layer is normally formed by a filter paper layer. The press forming is performed preferably at 20° C. to 160° C. and 1 MPa to 5 MPa. The mass per unit area of the upstream layer is preferably 1 g/cm2 to 15 g/cm2. The density of the fibers forming the nonwoven fabric is 0.9 g/cm3 to 1.5 g/cm3.

Abstract: A passive shim arrangement for a nuclear magnetic resonance apparatus has a plurality of nonmagnetic tubes disposed at predetermined positions around a common axis. Each tube is parallel to and uniformly distant from the axis. Magnetic shims are inserted into the tubes to correct components of the magnetic field.

Abstract: A method for manufacturing spring assemblies, in which a spring is fixed to a hole formed in a linear or an annular metal plate by compressing side edges of the plate to collapse the hole after inserting an end of the spring therethrough. The process is simple, and the obtained spring assemblies have excellent durability because there are not any projecting parts for installing springs on the metal plate, which are otherwise a factor in fatigue failure.

Abstract: A pipe hanger includes a pipe holder made from a strip of sheet material formed into a loop and a fitting element which is adapted to be suspended from a ceiling and to which the looped strip is secured. The looped strip has hooks adapted to fit into apertures in the fitting element to initially temporarily mount the looped strip on the mounting element, with complete securement being subsequently effected by fastening means.

Abstract: A pipe hanger includes a pipe holder made from a strip of sheet material and having a lower pipe supporting portion and an upper mounting portion. The lower pipe supporting portion is generally circular and has an opening through which the pipe is inserted. A fitting element mounted on the upper mounting portion and serves to suspend the pipe hanger from a ceiling or the like.
