  • Patent number: 10714171
    Abstract: According to one embodiment, a memory system comprising: a semiconductor storage device including a memory cell connected to a word line and capable of storing n-bit data (n is an integer of 2 or more); and a controller circuit, wherein the semiconductor storage device determines a value of the n-bit read data stored in the memory cell, by a first reading operation using k reading voltages different from each other (k is an integer equal to or higher than 2{circumflex over (?)}(n?1) and less than 2{circumflex over (?)}n?1), and the controller circuit converts the value of the n-bit read data into data corresponding to (k+1) decimal data.

  • Publication number: 20110260015
    Abstract: A visual presenting apparatus includes a support column which is mounted via a pivot shaft on a base so as to be pivotable, a friction braking mechanism applying a frictional load to the pivot shaft over a whole range of pivotal movement of the column, a power assist mechanism which applies a spring force to the column to urge the column rearward, a video camera head mounted on a distal end of the column and located over a document placed on an installation surface of the base, thereby imaging the document. The column is pivotable between a forwardly-tilted position and a folded position. The power assist mechanism is operatively coupled with the column when the column is tilted forward from an upright position. The power assist mechanism is released from the coupled state when the column is tilted rearward from the upright position.

  • Patent number: 5308032
    Abstract: The present invention relates to a knuckle bracket for use in mounting a vehicular shock absorber. The knuckle bracket has an outer bracket and an inner bracket, the outer bracket comprising an annular portion and a pair of clamp portions extending in parallel from the annular portion, the inner bracket comprising a bent backrest portion and a pair of support pieces extending in parallel from the backrest portion. The support pieces of the inner bracket are inserted between the clamp portions of the outer bracket, and a reinforcing bracket is provided at least between the support pieces of the inner bracket to prevent deformation, tilting and disengagement of the knuckle bracket.
