Abstract: In the webbing retractor, a lock plate is supported by a circular axis so as to be circularly movable freely by a resin support portion of a gear case by insertion of the circular axis of the lock plate in a support hole of the gear case. Even at times when great load acts on the lock plate at the support portion side, deformation of the support portion caused by movement towards the support portion side of the lock plate is prevented due to the tip of the circular axis of the lock plate contacting the metal blocking portion of the cover plate. Due to this, release of the support of the lock plate by the support portion is prevented.

Abstract: A combination includes a family of cartridge drives (12) including a first cartridge drive and a second cartridge drive, and a family of cartridges (14) including a first cartridge and a second cartridge. The first cartridge drive includes a first protrusion pattern (32), and the second cartridge drive includes a second protrusion pattern (32) that is different than the first protrusion pattern (32). The first cartridge includes a first recess pattern (62) that receives the first protrusion pattern (32) thereby allowing full insertion of the first cartridge into the first cartridge drive. The second cartridge includes a second recess pattern (62) that receives the second protrusion pattern (32) thereby allowing full insertion of the second cartridge into the second cartridge drive. The second protrusion pattern (32) can impede full insertion of the first cartridge into the second cartridge drive.

Abstract: Disclosed is a self-locking safety belt retractor comprising a blocking element which can be triggered in a belt band-sensitive and/or vehicle-sensitive manner and blocks the rotation of the belt shaft in the unwinding direction of the belt, and a tensioning drive which acts upon the belt shaft and rotates said belt shaft in the winding direction of the safety belt when being triggered. The inventive safety belt retractor is characterized by the fact that the tensioning drive which is provided with two parts (14, 15; 26, 32) that move relative to each other when said tensioning drive is triggered, is disposed on the belt shaft without being connected to the housing (10) of the belt retractor and rotates along with the belt shaft before being triggered. Furthermore, one part of the tensioning drive is fixed by means of the blocking element (17) as an abutment for the tensioning movement of the second part of the tensioning drive when the tensioning drive is triggered.

Abstract: In a webbing take-up device, when the release of a webbing belt is detected from the signal of a buckle switch, a motor starts driving, the webbing belt is taken up, and a computing circuit increases a voltage Eb in accordance with an integrated time after the signal is switched. In this state, a lock current flows due to an output shaft of the motor being stopped, and when the power to the motor is cut off by increasing the lock current, the values of voltages El and Ed respectively corresponding to the integrated time in which the lock current is powered and the integrated time in which the power to the motor is cut off are subtracted from the value of the voltage Eb, and the motor is driven until the computing result reaches a predetermined value.

Abstract: A recording tape cartridge with a reel in a case, a hollow cylinder shaped hub and a recording tape wound around the hub has a braking member provided so as to be unrotatable within the case. The braking member can be set at a locking position, at which the braking member engages with an engaging portion formed at a top surface of a floor of the hub and impedes rotation of the reel, and a rotation permitting position, at which engagement with the engaging portion is cancelled due to the braking member moving away from the top surface of the floor of the hub due to pushing-up of an operation portion which is inserted through a pass-through hole of the hub. A guide wall, which extends toward the braking member and always opposes a side surface of the operation portion, is formed at a peripheral edge of the hole.

Abstract: A recording tape cartridge includes: a case accommodating a reel on which a recording tape is wound; a brake member provided non-rotatably with respect to the case; a lock member provided in a mounting portion on the inner surface of a top plate of the case to be slidable in a radial direction of the reel; and a falling-out preventing member for keeping the lock member from being removed from the mounting portion. The brake member is arranged to selectively assume a rotation locking position where the brake member is engaged with the reel to prevent the reel from being rotated and a rotation permitting position where the brake member is disengaged from the reel to permit the reel to be rotated. The lock member is arranged, when the brake member assumes the rotation locking position, to be interposed between the upper surface of the reel and a top plate of the case, thereby preventing the reel from being moved axially thereof.

Abstract: A wire feeding device for very fine wire includes a straightening unit, a transporting unit, a wire buffer, and a wire guide arranged on a table on which a swivel unit with a wire drive is also arranged. The swivel unit serves wire-processing stations of a wire-processing machine. A supply of very fine wire is held in a drum and passes through the straightening unit which straightens the wire, bends and kinks being thereby removed. The transporting unit pulls the wire out of the drum and through the straightening unit and feeds the wire buffer. The wire buffer has a measuring device for monitoring a hanging wire loop. Depending on the requirement for wire in the wire-processing machine, the content of the buffer can decrease and the wire apex of the loop then moves upwards. The movement of the wire apex is detected by the measuring device and controlled with a control device via the transporting unit.

Abstract: In a recording tape cartridge, a reel locking member, which is positioned at a rotation locking position meshes with an engaging gear which is in a form of internal teeth and which is at a reel, such that rotation of the reel with respect to a case is impeded. When a clutch member is pushed up, a rotating cam member, which is screwed together with the clutch member, rotates toward one side, and the reel locking member moves to a releasing position by a positive motion cam structured by a cam projection and a cam groove. When the clutch member is pushed downward, the rotating cam member rotates toward another side, and the reel locking member moves to the rotation locking position by the positive motion cam.

Abstract: A recording tape cartridge which, with a structure having good produceability, can prevent wear of regions of abutment of a braking member and a releasing member at a time when a reel rotates. In the recording tape cartridge, when the braking member is positioned at a rotation locking position at which the braking member is engaged with an engaging gear provided at a floor portion of a reel hub, rotation of the reel, which is accommodated within a case, with respect to the case is impeded. When the braking member is held at a rotation permitting position at which engagement is released while the braking member abuts a clutch member, rotation of the reel with respect to the case is permitted. The braking member and the clutch member are respectively formed by resin molding, and abut one another at a slide-contact projection which is a resin portion, and a metal plate which is fixed to a clutch main body by caulking.
