摘要:
A mechanical shaft joint boot integrally made up of a large-diameter ring portion and a small-diameter ring portion with a bellows portion interposed therebetween, and a straight portion connecting the bellows portion with the large-diameter ring portion. The distance 11 between the large-diameter ring portion and the small-diameter ring portion is smaller than the distance l2 between a large-diameter ring mounting portion and a small-diameter ring mounting portion of the joint, and the outside diameter of a first crest of the bellows portion is not larger than the inside diameter of the straight portion. Accordingly, when a shaft of the joint inclines to cause inclination on one side of the boot, a surface pressure being imposed on the first crest is not increased correspondingly, thereby suppressing its wear and enhancing service time of the boot.

A conversion apparatus and method is disclosed by which a file including data multiplexed therein can be edited or handled readily while maintaining the compatibility. A standard/independent conversion section converts a file of a standard AV multiplex format wherein video data and audio data are placed in a multiplexed state in a body into a file of an AV independent format wherein video data or audio data are placed collectively in a body. Meanwhile, an independent/standard conversion section converts a file of the AV independent formation into a file of the standard AV multiplex format.
摘要:
A data accessing and reproducing apparatus and method that permits a user to selected desired video clips and perform editing on the clips such that the time needed to display a thumbnail representation is minimized. In an edit mode, thumbnail pictures are arranged and displayed in the order of which edit results are reproduced. These thumbnails may be, for example, a lower resolution, proxy representation of the audio or video data. When data of thumbnail pictures are read from a disc, the data are read in the order of which they have been recorded. The order of which thumbnail pictures are displayed on the screen is different from the order of which they are arranged on the screen, and thus, the seek time for the disc becomes the shortest. Thus, the thumbnail pictures can be displayed at high speed.
摘要:
A method for forming a dense coating on a limited region of a subject body is disclosed. The method is composed of the steps of: applying one selected from the group of a compressed body of a powder of a metal and a sintered compressed body of a powder of a metal to a working electrode; executing discharge deposition to deposit a first coating from the working electrode on the subject body by applying the subject body as a workpiece of the discharge deposition; executing discharge deposition to deposit a second coating from the working electrode on the first coating by applying the subject body as a workpiece of the discharge deposition; and heating the subject body in one selected from the group of a vacuum, an air and an oxidizing atmosphere so as to densify the second coating or oxidizing the second coating at least in part to generate a solid lubricant substance.
摘要:
A cutting instrument (1) has a cutting blade portion (13) formed with a skin (7) made of an electrode material or a reaction product of the electrode material, the electrode material having been molten by pulse discharges induced between the cutting blade portion (13) and an electrode in a machining liquid or gas, having as the electrode one of a mold molded from powder of a kind or powder of a mixture of kinds out of a metal or metals, a metal compound or metal compounds, and a ceramic or ceramics, and a heat-treated mold being the mold as heat-treated.
摘要:
An electrode for electric discharge surface treatment, in which a pulse-like electric discharge is caused between the electrode and a work in a dielectric fluid or an atmosphere, and in which a coat of an electrode material or a substance that is generated by a reaction of the electrode material due to an electric discharge energy is formed on a surface of the work, is a molded powder that is formed by molding a material powder including a metallic powder, a metallic compound powder, and a conductive ceramic powder. A powder solid that is formed as a result of coagulation of the material powder, and that is included in the molded powder has a diameter shorter than a distance between the electrode and the work.
摘要:
An electrode is used to perform discharge surface treatment of a work piece. The electrode is made of a green compact obtained by compression-molding an electrode material including powder of any of a metal, a metallic compound, and ceramics. The discharge surface treatment includes generating an electric discharge between the electrode and the work piece in an atmosphere of a machining medium and forming a film consisting of a machining material on a surface of a work piece using energy produced by the electric discharge. The powder has an average particle diameter of 5 micrometer to 10 micrometers, and contains 40 volume percent or more of a component not forming or less easily forming carbide as a component for forming the film on the work piece. The electrode has a hardness in a range of B to 8B tested with a pencil scratch test for a coating film.
