Abstract:
A cylindrical shaft which is formed in a cylindrical shape by pressing process in a state in which a pair of ends are opposite to each other is disclosed. A joint is formed between the pair of ends, and includes a plurality of intersection portions extending in a direction intersecting with an axial direction of the cylindrical shaft, a first straight portion connecting the ends of one side each of the pair of adjacent intersection portions, and a second straight portion connecting the ends of the other sides of the pair of adjacent intersection portions and being shorter than the first straight portion. A distance between the pair of ends at the first straight portion is shorter than a distance between the pair of ends at the second straight portion.
Abstract:
A cylindrical shaft is provided of which a pair of ends are formed in a cylindrical shape by a press work so as to form a joining portion therebetween. Here, the joining portion includes: a central linear section which is provided on a center portion in an axis direction of the cylindrical shaft and is formed in a linear shape to be parallel to the axis direction of the cylindrical shaft; and a folded section which includes a plurality of intersections which are provided on both ends of the center portion and are disposed so as to be extended in a direction perpendicular to the axis direction of the cylindrical shaft, and a connection linear section which connects ends of a pair of the adjacent intersections.
Abstract:
There is provided an information processing apparatus including a display control unit that displays a list screen of thumbnails associated with content, an execution unit that executes any application using the content associated with the thumbnails, and an image generation unit that generates an execution state image showing an execution state of the application by the execution unit, wherein the display control unit displays the execution state image generated by the image generation unit in at least a portion of an area where the list screen is displayed.
Abstract:
An information processing apparatus includes a program information display controller configured to display recommendation information which relates to a recorded program, which is obtained in advance, and which is introduced in the program, and configured to display, when the recommendation information is searchable by web searching, a notification describing that the recommendation information is searchable by the web searching along with the recommendation information, and a search display controller configured to determine at least one search site in accordance with a type of the recommendation information when a user selects the searchable recommendation information and display a search dialog including the determined at least one search site as at least one candidate.
Abstract:
A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.
Abstract:
A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.
Abstract:
To improve the sliding characteristics of a magnetic head by reducing a friction coefficient, and realize a magnetic recording medium with a high recording density and a large capacity, capable of reducing the flotation distance of the magnetic head. On the surface of a base, aluminum containing nitrogen aggregates locally to form islands of metal deposits, which are distributed discretely over the entire surface of the base. Meanwhile, on the metal deposits, a metal base layer, a magnetic layer, a protective layer, and a lubrication layer are laminated sequentially to form a magnetic recording disk. On the disk surface, ultrafine irregularities are formed that reflect the shapes of the metal deposits, thereby realizing a reduction in the friction coefficient.
Abstract:
A polycarbonate resin composition comprising (A) a polycarbonate resin containing from 10 to 6,000 ppm of phenolic residues, (B) a partial ester of an aliphatic saturated monovalent carboxylic acid and a polyhydric alcohol in amount of from 0.001 to 0.5 part by weight per 100 parts by weight of the component (A) and (C) a mixture of one or more of an aliphatic higher monohydric alcohols in amount of from 0.003 to 1.0 part by weight per 100 parts by weight of the component (A).By the use of this composition, a molding having an excellent appearance can be produced.
Abstract:
A surface configuration inspection apparatus comprising a movable member having a grating with parallel equidistant dark and light lines on a transparent plate, and a driving device for causing the vertical movement of the movable member. A projection device projects an image of the grating onto a screen disposed by the object to be inspected. A detector detects the image of the grating on the screen by reflection from a reflective surface on the object to be inspected and displays a deformed pattern of the grating. The deformed pattern changes with the movement of the grating. According to the deformation and the change of the deformation, defects such as projections, depressions, scratches or the like can be identified as to their size and shape.
Abstract:
Novel substituted hydrazide derivatives of 7-(substituted)amino-3-methylene-cepham-4-carboxylic acids expressed by the formula ##STR1## wherein R.sub.1 represents alkyl containing at least 3 carbon atoms, cycloalkyl, or optionally substituted aryl, and one of R.sub.2 and R.sub.3 represents hydrogen with the other being hydrogen or the same as R.sub.1 ; or R.sub.1 and R.sub.2 form a heterocyclic ring optionally through a hetero atom together with the attached nitrogen and R.sub.3 represents hydrogen atom; and Z.sub.1 represents amino or protected amino; and acid addition salts thereof, which are useful as intermediates for synthesizing cephalosporin antibiotics. These compounds can be prepared in high yields from the corresponding substituted hydrazide derivatives of 6-substituted amino-1-oxide-2, 2-dimethyl-penam-3-carboxylic acids, which are readily available at low costs, by heating them in the presence of a thermal rearrangement promotor such as organic sulfonic acids and optionally in the further presence of a tertiary nitrogen-containing cyclic compound, followed if desired by splitting off the amino-protecting group and converting the product to acid addition salts.
