Abstract: In an optical transmitter for optical communication, optical interconnection and so forth, one laser diode diode (LD) for emitting an optical signal is selected out of an array of LDs in response to address signals. This prevents the other or unselected LDs from consuming power and thereby obviates an increase in power consumption ascribable to an increase in the number of channels.

Abstract: In a magnetic recording apparatus, a magnetic recording medium has a disk body and a lubricant covering not only the opposite major surfaces but also the inner circumferential edge of the disk body. The medium prevents the lubricant from flying about despite the spinning thereof and, therefore, remains mechanically durable over a long period of time.

Abstract: A system and method for distribution of RF communication signals. First RF communication signals are downconverted in a first signal processing subsystem and transmitted to a second signal processing subsystem via twisted-pair cable. The downconverted first RF communication signals are upconverted at the second signal processing subsystem to provide recovered first RF communication signals, and the recovered first RF communication signals are transmitted via an antenna. Operating power for the second signal processing subsystem is provided from the signal processing subsystem, and the second signal processing subsystem determines the occurrence of an event and transmits autonomous information signals thereabout to the first signal processing subsystem.

Abstract: A tricycle has a fourth and rear supporting wheel at a distance from and a position above the usual rear tricycle wheels so that the tricycle may be tipped to raise to simulate a wheelie. The distance between the usual rear tricycle wheels and the front wheel is adjustable, so that the maximum wheelie angle may be selected according to the child's age and proficiency. The seat may be moved to make it easier or more difficult to tip the tricycle when the child shifts his body and, therefore, the center of gravity.

Abstract: A universal radiographic/fluoroscopic "room" is constructed according to the present invention by combining a versatile group of X-ray examination system components, electrical and mechanical drive components, and sensing components, under the supervision of a flexible control system, to form a universal diagnostic medical imaging system capable of performing radiographic, fluoroscopic, tomographic, and stepped examinations in several different operator-selectable configurations. The operator selects any available operating mode, including auto-bucky, auto-wall, auto-table, auto-table/wall, servo-tomo, conventional stepping, stepped-digital, auto-step, and auto-step-center modes, using a a control panel. The control system automatically determines which system components are required to perform that type of examination, moves the components into operational or storage positions as required, and prepares each component for operation. The operator need not manually reconfigure the equipment.

Abstract: An interdental toothbrush handle for holding a twisted wire brush includes a handle with a locking retainer connected thereto by a living hinge. The handle has two opposing side walls which extend perpendicularly from the handle and are adjacent to the living hinge. At least one of the walls includes a V-shaped gap for receiving the stem of a twisted wire brush. The handle also preferably has an indentation between the two opposing side walls and the locking retainer preferably includes a protrusion in communication with the indentation. A nub on the protrusion prevents the locking retainer from opening more than about 30.degree. to 40.degree..

As the locking retainer is closed, the stem of the twisted wire brush is captured between the handle and locking retainer.
