摘要:
One side portion of an intermediate member 6 is inserted in one side portion of a tubular portion 71 of a fixed member 7 and rotatably coupled to the one side portion of the tubular portion 71 in this state. A vertical slit 71c is formed in the other side portion of the tubular portion 71 of a fixed member 7 so as to extend across the tubular portion 71. A lateral slit 71d that extends in a circumferential direction of the tubular portion 71 is formed at an intersection portion of the tubular portion 71 and the attachment plate 72 so as to intersect with the vertical slit 71c at a center portion of the lateral slit 71d. The vertical slit 71c and the lateral slit 71d define, as a displacement portion 71e, 71e, a portion that can be displaced to a radial direction outer side of the tubular portion 71. The displacement portion 71e is displaced to the outer side by being pressed by a pressing portion 61c of the intermediate member 6 when the intermediate member 6 is rotated to an attachment position at which substantially all of a main body 61 of the intermediate member 6 is inserted into the tubular portion 71.

In the clutch pinion slidably fitted on a spool shaft so that an engagement projection of the spool shaft can be engaged with and disengaged from a clutch engagement recess of the clutch pinion. The clutch pinion is integrally formed with planar surfaces and inclined surfaces for defining clutch the engagement recess in the form of a transverse slot. The pinion has a pinion tooth portion from one end to the other end thereof, and has an annular engagement portion in the form of an outer peripheral groove in which a clutch plate is engaged. The planar surfaces and the inclined surfaces which are disposed around a clutch engagement recess are integrally connected together in order to reduce a change in the distance between the planar surface, thereby always maintaining a stable rotation transmission and a clutch performance.

A hinge device has a base, a body removably provided at the base, and a mounting member rotatably connected to the body. The base has a base member, a first movable member disposed at the base member such that the first movable member is movable in a first direction and non-movable in a second direction orthogonal to the first direction, and a second movable member disposed at the first movable member such that the second movable member is movable in the second direction and non-movable in the first direction, and the body removably attached to the second movable member. A first position adjustment mechanism is provided between the base member and the first movable member. The first position adjustment mechanism adjusts position of the first movable member with respect to the base member in the first direction.

An information processing apparatus performs topic analysis on one or more collected documents to calculate a probability indicating the degree of fitness of each sentence constituting the collected document for each item of a local topic, performs linguistic analysis on the collected document to detect a unique expression pattern in each item of the local topic, sets topic usefulness for each sentence constituting the collected document on the basis of evaluation of the sentence by an evaluator, sets a total evaluation value with respect to each item of the local topic on the basis of the topic analysis result and the topic usefulness, selects an item of the local topic on the basis of the total evaluation values, and extracts an appropriate sentence for a unique expression pattern in the selected item of the local topic from the collected document as a profound text candidate.

An information processing apparatus includes: a document analyzing unit that extracts phrases including a pair of entities, to which a relevance label is granted, from document data; and a label granting unit that grants the relevance label. The label granting unit acquires vocabulary syntax patterns included in the phrases including the pair of entities, acquires the appearing number of times the vocabulary syntax pattern appears in the document data from the document data, counts the number of pairs of entities, sets a probability model created from a probability density distribution, a parameter Z indicating validity of the granting of the relevance label, and a parameter a indicating a probability of rightly granting the relevance label, calculates the parameters Z and a for which a likelihood is maximum in the probability model, evaluates the validity of the granting of the relevance label, and grants the relevance label on the evaluation result.

One side portion of an intermediate member 6 is inserted in one side portion of a tubular portion 71 of a fixed member 7 and rotatably coupled to the one side portion of the tubular portion 71 in this state. A vertical slit 71c is formed in the other side portion of the tubular portion 71 of a fixed member 7 so as to extend across the tubular portion 71. A lateral slit 71d that extends in a circumferential direction of the tubular portion 71 is formed at an intersection portion of the tubular portion 71 and the attachment plate 72 so as to intersect with the vertical slit 71c at a center portion of the lateral slit 71d. The vertical slit 71c and the lateral slit 71d define, as a displacement portion 71e, 71e, a portion that can be displaced to a radial direction outer side of the tubular portion 71. The displacement portion 71e is displaced to the outer side by being pressed by a pressing portion 61c of the intermediate member 6 when the intermediate member 6 is rotated to an attachment position at which substantially all of a main body 61 of the intermediate member 6 is inserted into the tubular portion 71.
