  • Publication number: 20050021508
    Abstract: Information that individual elements (characteristic character rings) indicative of characteristics of a registered document appear in the registered document is stored in advance. When calculating similarity of the registered document, a query designated by a searcher is analyzed. The query is represented by a characteristic vector having the individual elements which take the relation between a plurality of words into consideration. Pieces of appearance information of the individual words contained in the query are counted. The counted appearance information is compared with a searching index to calculate similarity between documents.

  • Publication number: 20040193584
    Abstract: Character strings are extracted from a seed text which is inputted as a search condition for searching prestored object documents for a relevant document. Each object document is partitioned into a plurality of blocks, and character strings are extracted from each block. Similarity of each block to the seed text is calculated by comparing the character strings extracted from the block and the character strings extracted from the seed text. Whether or not each block is relevant to the seed text is judged by comparing the calculated similarity of the block with a preset threshold value. Based on the judgment, an “inclusion degree” of each object document (including the blocks) regarding the seed text is calculated, by which object documents relevant to the seed text are outputted.

  • Patent number: 6325567
    Abstract: An arm member is used as, for example, a suspension arm of an automobile. The arm member comprises a main body made of a pipe member and a coupling member having a connecting portion. The pipe member is made of aluminum or its alloy. The coupling member is made of aluminum and includes a bushing mounting portion for mounting a vibroisolating bushing. The thickness of the peripheral wall of the end portion of the main body is increased in thickness to have a thickness thicker than that of the other portion of the main body. The connecting portion is abutted to the peripheral wall of the end portion to form an abutted portion, and connected thereto at the abutted portion. Thus, the coupling member is coupled to the main body.

  • Patent number: 6298962
    Abstract: There is disclosed a member for use with an arm that is used as an automobile suspension arm, for example. The member comprises a rodlike body and bushing-mounting portions formed at both ends of the rodlike body. The rodlike body consists of a hollow tube fabricated by extruding an aluminum material into a circular cross section. The bushing-mounting portions are formed by welding bushing-mounting members to both ends of the rodlike body. Each bushing-mounting member has a hole in which a bushing is mounted with a press fit. The curved wall of the rodlike body is recessed at the longitudinal center of the rodlike body. When an automobile having the aforementioned member collides, an axial compressive load is applied to the rodlike body. The rodlike body buckles at the recessed portion. This mitigates the impact in the collision.

  • Patent number: 6125539
    Abstract: A process for producing a vibration isolator. The process involves steps of forming an intermediate product including an axial member, an outside member having a cylinder-shaped portion and a rubber elastic member, and drawing the cylinder-shaped portion with a drawing apparatus provided with a drawing hole at least by pressing the cylinder-shaped portion into the drawing hole. The drawing hole has a predetermined dimensional diameter being smaller than an outer peripheral diameter of the cylinder-shaped portion. Thus, the cylinder-shaped portion is reduced diametrically to plastically deform. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

  • Patent number: 6094818
    Abstract: A process for producing a vibration isolator includes the steps of preparing an axial member, an outside member, the outside member including a cylinder-shaped portion and a bracket having a hollow, and a cylinder-shaped rubber elastic member, and drawing the cylinder-shaped portion by inserting a stationary mold, with which a drawing apparatus is provided, into the hollow of the outside member so that an outer peripheral surface of the cylinder-shaped portion contacts with the stationary mold, by disposing the rubber elastic member and the axial member inside the cylinder-shaped portion, and by pressing the cylinder-shaped portion onto the stationary mold and simultaneously diametrically reducing the cylinder-shaped portion to plastically deform the same. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

  • Patent number: 5947455
    Abstract: A vibration-proof mount includes an inner shell member comprised of a center pipe and a bush, and an outer shell member including a first collar and a second collar. The center pipe and the outer shell member are connected to each other by first and second elastomer members with a liquid encapsulated therein. A liquid chamber is formed between the first and second elastomer members and expanded and contracted in volume by a load, and an orifice is defined in the first elastomer member and connected to the liquid chamber. The orifice is formed by only a wall surface of the first elastomer member and hence, the sectional area of a flow path in the orifice can be insured to prevent a difference in characteristic between individuals of the vibration-proof mount, as compared with the case where the orifice is defined between a plurality of members.
