Abstract: In reading a magneto-optical recording medium comprising a substrate and a magnetic multilayer on a surface of the substrate, which multilayer comprises, in order from the surface of the substrate, an amplifying layer A.sub.1, a control layer C.sub.2, and a recording layer R.sub.3 with a magnetic domain formed therein, the medium is first irradiated with a laser beam while a reading magnetic field is applied thereto in one direction. With the resulting temperature increase, the magnetic domain in R.sub.3 is successively copied from C.sub.2 to A.sub.1 to form copied magnetic domains, which are in turn enlarged by a reading magnetic field. Then, the enlarged, copied magnetic domain in A.sub.1 is read out. Thereupon, laser beam irradiation is interrupted or the power of the laser beam is decreased to thereby vanish the copied magnetic domains in A.sub.1 and C.sub.2. To carry out reading by light intensity modulation, an interface wall exchange force magnetic field between the respective magnetic layer, etc.

Abstract: An optical recording medium comprises a substrate and a multilayer structure on the substrate. The multilayer structure comprises a phase change type recording layer and a pair of dielectric layers, at least one of which contains zinc sulfide optionally with silicon oxide. When a depth profile of the multilayer structure in a thickness direction thereof is found by Auger electron spectroscopy, a region having an intensity ratio S/Zn of 2 or lower exists across a thickness of at least 6.0 nm, calculated as SiO.sub.2, from the vicinity of an interface between the dielectric layer and the recording layer into the recording layer. In the vicinity of the interface between the dielectric layer and the recording layer, there is also a region having an intensity ratio S/Zn vs. O/Si relation that satisfies S/Zn<O/Si.

Abstract: An electrical power system to provide a selected voltage to a load such as a fluorescent lighting system is characterized by a winding 3 having a positive end connected to a positive rail and is tapped at a predetermined position for supplying an output terminal with a selected voltage. A first relay contact can electrically connect a neutral end of the winding to a neutral rail to provide one selected voltage or a second relay contact can electrically short-circuit a predetermined number of turns of the winding in response to a request for a second selected voltage. When a fault condition is monitored, a third relay contact can electrically short-circuit the neutral end of the winding to the predetermined position to put the system into a failsafe condition which prevents turns of the winding being open circuit.

Abstract: The present invention refers to a tool-changing mechanism that can be used especially in combination with a metal-forming press. Especially in the case of big and heavy forming tools, pairs of tools are difficult to exchange. The present invention intends to provide the possibility of exchanging also tools of this type rapidly and easily, the tool exchange being, in addition, carried out automatically, if desired. For this purpose, the tool-changing mechanism (1) includes a circulating means provided with a plurality of reception means (4a, 4b) for holding forming tools (5a, 5b). The tool-changing mechanism is adapted to be set up beside a metal-forming press. At a tool changing position, the tools can be pushed into the metal-forming press. Furthermore, the present invention refers to an arrangement comprising a metal-forming press and a tool-changing mechanism in the case of which said tool-changing mechanism is arranged directly at the side of the metal-forming press (10).

Abstract: A new dimple configuration for the surface of a golf ball is characterized by non-circular sickle-shaped dimples. Each dimple includes a convex outer edge having a first radial configuration and an inner edge having a second radial configuration. Preferably, the inner edge is concave and the inner and outer edges meet at opposite sides of the dimple. The area between the edges is recessed relative to the golf ball surface. At least some of the sickle-shaped dimples are arranged in an interlocking pattern to maximize the dimpled area of the golf ball surface.

Abstract: A surgical needle to simplify rotator cuff muscle tendon surgery and reduce the cost thereof, has a semi-circular body including a proximal end portion terminating in a point, a blunt distal end, an intermediate portion, and through-openings at each end. The proximal end of the needle is passed through bone and exits a trough formed therein. A suture from the rotator cuff tendon is passed through the proximal end through-opening. Thereafter, the needle is backed out from the bone, drawing the suture through the bone, following which the suture is tightened and secured to retain the rotation cuff tendon within the trough of the bone.

Abstract: The invention concerns a method and apparatus for regulating the distance between the frame and a wheel unit or axle of a motor vehicle by means of a hydrodynamic suspension element by varying the volume of the damping liquid. The vehicle frame is sprung and damped at both sides of the vehicle relative to one or more wheel axles by means of hydropneumatic springs, wherein one of the volumes of the hydropneumatic springs is variable. In this arrangement, to increase the distance the static volume is supplemented by an additonal volume and to reduce the distance the static volume is reduced by a reduction volume. Associated with one or more parallel-connected hydropneumatic springs is a metering unit which can add or withdraw at least one defined additional volume and/or reduction volume with respect to the instantaneous sum of the damping volumes of the associated hydropneumatic springs.

Abstract: With an abrasive dresser for a polishing disc of a chemical-mechanical polisher for abrading a flat rotatable polishing disc of a chemical-mechanical polisher which supplies a chemical polishing agent to the surface of the polishing disc to polish the surface of an article on top of the polishing disc, a sectional shape of an abrasive surface being a peripheral portion of a flat disc shaped base member which protrudes upwards over a predetermined width with an abrasive grit distributed substantially uniformly over and affixed to the surface thereof, is formed as a convex circular arc curved surface. In this way, the portion of contact with the polishing disc of the chemical-mechanical polisher becomes surface contact, thereby enabling a reduction in wear during use and an increase in life, together with an increase in the efficiency of abrading the polishing disc.
