Title: Optical disc beam focus control
Inventor: WILKINSON RICHARD L
IPC: G11B7/08
Filed: 1981-05-14
Granted: 1984-10-25
Abstract: A control system for maintaining proper focus of a radiant recording or writing beam, such as a laser beam, with respect to a recording surface, by measurement of the duty cycle of an oscillatory information-carrying signal recorded from the recording surface immediately after recording. The system includes a photodetector for detecting a reading beam used to recover the recorded information, a focusing lens movable with respect to the recording surface to focus the writing and reading beams, a dither oscillator to generate a dither signal employed to move the focusing lens in an oscillatory manner, a duty cycle detector to provide a signal indicative of the duty cycle of the information-carrying signal recovered by the reading beam, and a multiplier for comparing the phases of the duty cycle signal and the dither oscillator signal, and thereby providing a correction signal indicative of the magnitude and polarity focus error. This control system provides fine focus control, and is utilized in conjunction with a coarse focus control comprising a focus detector, differential amplifier and feedback path to the movable focusing lens. In addition, the signal from the duty cycle detector can be coupled to maintain the power of the writing beam at an optimum level and to maintain the duty cycle at a constant level, such as fifty percent.

Title: End winding spacer block for free coil ends - consists of wedge shaped resin filled felt wraps with rigid centre-piece and additional felt insert
IPC: H02K3/50
Filed: 1971-10-29
Abstract: To secure the spacing between the end windings of coil or bar windings wedge shaped blocks are proposed. These are made by winding a strip of resin loaded felt (1) round a rigid centre piece (2), with an additional loaded felt insert (4) to give the required shape. The rigid centre is typically a hard laminate with a woven material base. The wedges are fitted uncured to the insulated end windings and can thus conform to the shape between coils (3). The subsequent curing process helps to bond the parts together as well as giving a rigid structure. The method of weding is applicable both to stator and rotor windings.

Patent JP-3365667-B2 (JP)
IPC: H04L12/56
Filed: 1994-01-17
Granted: 2003-01-14
Abstract: To efficiently implement the algorithm for branching each broadcast call as close to the output of a multi-stage switching fabric as possible, the path hunt for a call path is performed by examining the actual contents of control memories (in time slot interchangers (131,141) and time-multiplexed switch (120)) that control the switching stages of the switching system, in order to determine whether - and if so, where - the desired call path may be branched from an existing call path inside of the switching system. For efficiency and speed, the examination is performed by monitoring control memory contents being read out for the purpose of controlling the switching stages, and contents of control memories of multiple stages are monitored in parallel using dedicated monitoring hardware. To avoid the need to examine the control memories' contents in order to determine how much of a call path can be torn down without breaking call path segments shared with other existing call paths, separate counts are kept of instances of present use of connections between stages of the switching fabric, which counts are incremented upon creation of any branching paths that use these connections and are decremented upon breaking of any branching paths that use these connections. <IMAGE>
