  • Publication number: 20020158162
    Abstract: A seat belt retractor includes a base frame, a spool journalled to the base frame, a webbing wound around the spool, and a motor for rotating the spool. A speed-reduction mechanism is interposed between the motor and the spool. The speed-reduction mechanism includes at least one transmission train with a predetermined gear ratio, a common transmission element connected to the transmission train, and a resistant torque device connected to the transmission train. The common transmission element transmits rotation of the motor to the spool when the torque of the rotation is smaller than the preset value. Winding of the webbing is made based on the wearing condition of the webbing and the running condition of the vehicle.

  • Patent number: 6329893
    Abstract: A buckle is provided with a non-contact buckle switch to find an engagement condition with a tongue. When a lock member of the buckle is disposed in a locking position, a magnetic field produced by a magnet and applied to an IC Hall element differs from a case where the lock member is disposed in a non-locking position. The difference of the magnetic field is caused by the magnetic lock member moved close to the magnet and the IC Hall element, whereby an electrical current outputted by the electromotive force of the IC Hall element is changed. Thus, it is possible to determine that the lock pin is set in the locking position. The buckle switch is improved in durability and can operate more reliably.

  • Patent number: 5393943
    Abstract: An acceleration sensor is formed of a housing, an inertia member located inside the housing so as to be freely movable in a longitudinal direction of the housing, a conductor provided on at least an end surface of the inertia member in the longitudinal direction of the housing, a pair of electrodes disposed at one end side of the longitudinal direction of the housing, and electrically connected together by a conductive bridging inertia member. An attractor is disposed at the other end side of the longitudinal direction of the housing and magnetically attracts the inertia member. A stopper is disposed at an opposite side of the inertia member with respect to the electrodes, and abuts against the tip surface of the inertia member when the inertia member moves forwardly. The stopper is disposed at a position which is located off-center with respect to or deviated from the axial center line of the housing.

  • Patent number: 5173292
    Abstract: This invention provides a composition useful for diagnosing cancer which specifically recognizes a galactosyl-globoside. Preferably, the composition is a monoclonal antibody which specifically recognize the galactosyl-globoside antigen, gal-Gb4.Additionally, the present invention provides two hybridoma cell lines, designated J309 and D579, which produce monoclonal antibodies that specifically recognize gal-Gb4.The invention also provides a method of diagnosing a carcinoma which comprises contacting a sample from a human subject with a composition which specifically recognizes a galactosyl-globoside antigen and is labeled with a detectable moiety, under suitable conditions so as to form a detectable complex. The amount of formed complex is then quantified and correlated with values obtained from subjects devoid of carcinomas.

  • Patent number: 5059520
    Abstract: Monoconal antibodies HT29-36, CB, CLH6, M2, and S12 are useful in determining the presence of Type A blood group antigen and in distinguishing different forms of this antigen. As type A antigen exhibits several forms differing in minor respects only, the monoclonal antibodies are useful in making fine distinctions between the different forms, and may be used, e.g., in cancer diagnosis, and the like.

  • Patent number: 5006470
    Abstract: This invention provides a monoclonal antibody, produced by the hybridoma cell line designated GXM1, which specifically binds to a human class 1tumor antigen. This invention also provides a human monoclonal antibody, produced by a hybridoma cell line designated HJM1, which specifically binds to each of the ganglioside antigens GD2, GD3, GM3 and GD1b. This invention further provides a human monoclonal antibody, produced by a hybridoma cell line designated FCM1, which specifically binds to the ganglioside antigens GM3 and GD1a. Finally, this invention provides a human monoclonal antibody, produced by a hybridoma cell line designated DSM1, which specifically binds to a human class 2 tumor protein antigen.

  • Patent number: 4647239
    Abstract: A paper loading system for use in a printer has a platen and a paper bail mounted with two rollers. A carriage having a projection is provided to move parallelly to the platen. At the free end of the projection, a photodetector is provided to detect an edge of a loaded paper so as to memorize the opposite ends of the loaded paper. When the paper bail is in a pressing position at which rollers are holding the paper on a path of advance of the paper, no engagement is accomplished between the projection and the rollers. But when the paper bail is in a releasing position at which rollers are separated from the path to release the paper, the projection may come into contact with rollers to change the position of rollers. Using the memorized data, the movements of the carriage and the paper bail are controlled to locate the rollers at the opposite side rims of the loaded paper.

  • Patent number: 4601595
    Abstract: A paper sheet setting mechanism in a printer such as an ink jet system printer includes a memory device which stores a desired left setting position at which a left paper pressing roller should be positioned, and a desired right setting position at which a right paper pressing roller should be positioned. C-shaped guide plates are secured to the paper pressing rollers. Each of the C-shaped guide plates includes a roof member which is made contact with a pritrusion secured to a printer head when a shaft of the paper pressing rollers is held at a first stable position. When the printer head is driven to shift while the shaft is held at the first stable position, the paper pressing rollers are shifted on the shaft and controlled to be positioned at the desired left and right setting positions, respectively.
