Filed: 1991-06-12
Abstract: A  magneto-optical  disk  according  to  the  present invention has a substrate, a recording layer formed on the substrate  and  an  outer  layer formed  on  the  recording layer, above which a floating head is hovered.  The outer layer   is   constituted  of   a  protective   layer,   an antisticking layer for head, having a texture formed on its surface and other layers.  The magneto-optical disk is designed such that, when rotated at a constant angular velocity,   the   thickness   of   the   outer   layer   is substantially inversely proportional to a radial position r on the magneto-optical disk raised to the 1/2nd power.          In the formation of the outer layer, a screen whose meshes become gradually finer from the innermost portion toward the circumferential portion of the magneto-optical disk is employed based on the screen printing-technique.  Further, photo hardening resin is used as the outer layer,  and simply by changing a wavelength or irradiation amount of light to be applied thereto, a texture is readily formed on the surface of the outer layer.   By the use of the present   invention,   stable   recording,   erasing   and re-writing  operations  are  achieved,  and  it  becomes possible to prevent the floating head from sticking to the magneto-optical disk and reduce the cost thereof.

Abstract: A method in a mobile radio station to select one of a number of dedicated control channels (DCCH1-21) which are transmitted from a number of base stations (B1-B21) in a mobile radio system. In the mobile station there is an equalizer to compensate for the multipath propagation characteristics of the radio medium between the mobile station and a certain base station. This equalizer is power consuming and should not be used if not necessary. According to the method an investigation is carried out in the mobile station whether or not the equalizer can be disconnected during the initialization of a call from the mobile to a base station. The signal quality of the dedicated channel (DCCH1) which has the greatest signal strength is measured without the equalizer. If the signal quality is not acceptable, a new detection is made with the use of the equalizer. If the signal quality then is acceptable another detection is made without equalizer on the dedicated control channel (DCCH2) which has the next strongest signal and if this detection revealed an acceptable signal quality the base station (B2) transmitting this control channel is selected by the mobile station for the further call progress.

Title: Digital processor for two's complement computations
Inventor: MCWHIRTER JOHN G
IPC: G06F7/533
Filed: 1990-05-02
Abstract: A digital processor (10) for two's complement computations incorporates an array (12*) of multiplier cells (12) each having the one-bit gated full adder logic function. The array (12*) has nearest-neighbour connections (16, 18, 20) containing clock-activated latches (42, 44, 50) for bit propagation. On each clock cycle, the cells (12) receive input data, carry and cumulative sum bits.  Each cell (12) adds the carry and cumulative sum bits to the product of the data bit and a respective coefficient digit associated with the relevant cell (12). Data bits pass along array rows and sum bits accumulate in cascade down array columns. Carry bits are recirculated. Each coefficient digit is expressed as a sign bit and at least one magnitude bit consisting of or including a level bit. Each cell (12) includes multiplicative gating means (58, 62) responsive to the sign and level bits, and carry feedback means (60, 66) responsive to a least significant data bit flag to substitute the sign bit for a carry feedback bit. Each coefficient digit may include an additional magnitude bit expressed as a shift bit and employed to select multiplicand data bit significance, the gating means (58, 62) being responsive to flag bits to eliminate unwanted sign extension bit products. The processor (10 or 200) may include accumulating means (14 or 214) incorporating gates (90, 98 or 292, 298, 336) responsive to flag bits and arranged to eliminate unwanted result sign extension bits.

Inventor: SAYEGH EMILE
IPC: G01N21/53
Filed: 1991-10-11
Abstract: Optical analytical instruments to determine a physical parameter of a fluid, and methods of operation of such instruments, are shown. These employ a source of suitable optical radiation, a detector means, means defining a zone for the fluid, means defining an optical path from the radiation source through the fluid zone to the detector means, and reading and control circuitry. At least two readings of optical energy that has been influenced by the fluid are taken without there having occurred substantial change to the fluid. During one of the readings a filter of known absorbance is included in the optical path so that the respective reading represents a calibration reading. A calibration-value-determining means is constructed first to compare, effectively, the two readings to remove the effect of the fluid from the value of the calibration reading, second, to compare, effectively the residual value of the calibration reading to a known value based on the known absorbance of the filter, and, third, on the basis of the second comparison, to make a calibration adjustment based on values derived while the fluid sample remained unchanged in the fluid zone. Novel software implementations of the determinations are shown. Specific examples of instruments and methods implementing these features shown are a dual lamp, no-moving part in-line spectrophotometer, a no-moving part reflection colorimeter capable of on-line or off-line operation, a scatter or fluorescence detecting implementation and a turbidimeter.

IPC: G02B6/122
Filed: 1991-12-23
Abstract: A 2-input/2-output directional coupler is arranged as an element coupler/splitter for a first stage, and 1-input/2-output coupler/splitters are used as element coupler/splitters for a second stage and its subsequent stages. Output ports of these element coupler/splitters are concatenated with input ports of other element coupler/splitters to form a 2-input/multi-output coupler/splitter.      An optical signal can be inputted through one input port of the first-stage 2-input/2-output directional coupler, and an optical signal for optical line monitoring can be inputted through the other input port. It is unnecessary, therefore, to use an optical wavelength division multiplexer/demultiplexer or other optical part which conventionally is connected at the time of optical line monitoring.

Abstract: ABSTRACT           Inefficiency in heat exchange in an evaporator for a refrigeration system due to maldistribution of incoming refrigerant may be reduced in a structure wherein a plurality of hydraulically parallel flow paths are defined by tubes (20) having  ends  (84)  in  the  interior  of  a  header  (10).          Refrigerant inlets (70, 72) are provided for the header (10) at opposite ends (62, 64) thereof to generate streams (78, 80) of incoming refrigerant which impinge upon one another to dissipate the kinetic energy and/or momentum of the streams (78 and 80) which in turn results in an improved distribution of the refrigerant within the header  (10).   Refrigerant outlets are provided for a header.   The outlets are at opposite ends thereof to generate two streams of outgoing refrigerant which reduces outlet resistance and thus provides for more uniform flow of the refrigerant.
