Abstract:
A cable type steering system includes an operation cable having an outer tube and inner cable slidably received in the outer tube. A drive pulley coupled to a steering wheel for rotation is connected to one end portion of the inner cable, and a driven pulley coupled to a steering gear box for steering wheels for rotation. A driven pulley is connected to the other end portion of the inner cable. A steering torque inputted to the steering wheel is transmitted to the steering gear box via the inner cable of the operation cable. At least one of a first portion extending from the drive pulley to a first optional position of the outer tube and a second portion extending from the driven pulley to a second optional position of the outer tube is accommodated within a waterproof space.
Abstract:
A renovated brake structure for an auxiliary moving device comprises a grip, a cover, a brake wire and a handle. The cover is secured to the handle and the grip is pivoted to the cover. The grip is secured to one end of the brake wire with a stud, whereas the other end of the brake wire having a spring to urge the grip to resume to original position. The grip comprises a pair of linking rods with a rail and a connecting pin on each rod. Each linking rod is connected at one end to a stud which is to secure with on end of a brake wire. A pair of holes are formed at the front respective ends of the grip for insertion of the pins. An arc trough is formed at one end of the grip with an elastic stopper at one end and a locating hole at the other end. A stop pin extending from the cover is inserted through the arc trough of the grip to secure the grip to the cover. Thus, by pulling the grip either towards or away from the handle, the linking rods are pulled and the stop pin of the cover slides into the arc trough to stop the auxiliary moving device.
Abstract:
A first radioactive source assembly disposed in a first source channel and a guide tube connected to the source channel and having a second end which is disposable in the animal body. A first source assembly transport thread connects the first source assembly to a first source assembly drive for driving the first source assembly to the second end of the guide tube. At least one further radioactive source assembly is disposed in a further source channel, a connector tube connects the further source channel and a connector disposed in the guide tube. A juncture is formed at the connector. A further source assembly transport thread is attached to the further source assembly and to a further source assembly drive for driving the further source assembly towards said second end of the said guide tube. The first source assembly and the further source assembly are alternatingly drivable toward the second end of the guide tube. A detector detects the presence of either source assembly in the juncture whereby radiation therapy may be accurately effected by either the first source assembly or the further source assembly.
Abstract:
A control member of a remote control apparatus is provided with a first engagement member. A second engagement member is provided on the end of the core wire of a push-pull cable. The core wire and second engagement member are inserted through an opening in the control apparatus housing to effect engagement of the engagement members. The engagement members thereafter effect a pivoted connection therebetween as the cable is pivoted relative to the control member through an opening in the housing. The sheath of the pivoted push-pull cable is pivotally secured relative to the control apparatus housing.
Abstract:
A dial type wire control device includes a drum and a strap or band in combination. The drum is connected to a dial member through a connecting shaft so that the drum and the dial member can rotate synchronously. The band is to be wound on the periphery of the drum when the drum rotates in one direction and to be unwound when it rotates in the opposite direction. Thus, the wire is pulled or pushed to control a subject in a conventional manner.
Abstract:
A linear actuator incorporates a casing on which a crank is mounted. Rotation of the crank produces rotation of a gear which meshes with the inner portion of a rotatably mounted ring. A cable is attached to the outer periphery of the ring and extends through a series of nested balls which engage a grooved portion of an arcuate teflon strip. The other end of the cable is attached to a rod which is slidably mounted in a stationary tube. Rotation of the crank produces a linear movement of the rod.
