Title: Optical pick-up device and method for an optical pick-up device
Inventor: MORIMOTO YASUAKI
IPC: G11B7/1263
Filed: 1996-01-25
Abstract: In the case of an optical pick-up device for reading a magneto-optical recording medium, depending on the direction of rotation of its polarisation plane, the light beam reflected by the recording medium is reflected onto a first photodetector or a second photodetector. The data signal is obtained from the difference between the photoelectric voltages of the two photodetectors. 
<??>With a novel recording medium on which data are stored by means of pits and in magnetic domains, in order to be able to read both types of data simultaneously, the data signal PS, which represents the data which are stored by means of the pits, is obtained from the sum signal of the two photoelectric voltages. The data signal MS, which represents the data contained in the magnetic domains, is obtained from the difference signal of the two photoelectric voltages. The data signal PS can also be obtained by the transilluminating method by means of a photodetector (24, 25) provided behind the recording medium (5). The data signal MS can likewise be obtained by the transilluminating method by means of a polariser (27) and two photodetectors (28, 29) provided behind the recording medium (5), by forming the difference between their output signals, whereas the data signal PS is obtained from the light reflected by the recording medium (5).

Patent HK-42183-A (HK)
Title: Door closer
Inventor: CHADDOCK DENNIS HILLIAR
IPC: E05F3/12
Filed: 1983-10-13
Abstract: A door closer includes a tension member comprising spaced shafts acted by springs and connected to articulated chains which are coupled to an anchor plate secured to the door frame. Movement of the shafts is under the control of a uni-directionally operative fluid-filled damper having a piston carried by a piston rod which is connected to a cross head slidably mounted on the shafts and held against abutment washers by the springs. The damper serves to regulate the rate of movement of a door in the direction of closure without restricting significantly the rate of movement in the direction of opening. A fluid by-pass is provided in the damper by a rebate formed in the cylinder so that as the piston approaches the end of the cylinder over the final part of the closure movement the restraint imposed by the damper is relieved. The point in the closure movement at which the fluid by-pass becomes operative can be varied while the closer is installed so as to provide compensation for variations in the installation of the closer and variations of the gap between the door and its frame. In one embodiment this is achieved by securing the chains to an adjustment plate which is movable towards and away from the anchor plate. In another embodiment the piston rod is adjustable secured to the cross head, which in this case is in the form of a stirrup with a cross member on which the piston rod is carried presented towards and accessible from the outer end of the housing so as to enable the piston rod to be adjusted.
