Patent JP-H07110764-B2 (JP)
IPC: C01B25/165
Filed: 1990-05-30
Abstract: High purity alkali metal hypophosphites are produced in high efficiency by a simple step of using no separating agents other than white phosphorus, alkali metal hydroxides and water as reaction raw materials, resulting in no need of a complicated procedure for removing impurities. The process comprises reacting white phosphorus and an alkali metal hydroxide in an aqueous medium to prepare a crude solution of an alkali metal hypophosphite containing the phosphite, feeding the crude solution to a desalting compartment of an electrodialytic cell in which cation exchange membranes and univalent anion permeable membranes are alternately arranged between a cathode and an anode to form at least one pair of a desalting compartment and a concentrating compartment, so as to separate the hypophosphite from the crude solution, during which a dilute solution of an alkali hypophosphite is fed to the concentrating compartment, subjecting them to electrodialysis, withdrawing the purified solution of the alkali metal hypophosphite from the concentrating compartment and concentrating and crystallizing the thus purified solution.

Abstract: 1488536 Measuring deflection by optical interference KRAUTKRAMER GmbH 24 Nov 1975 [4 Dec 1974] 48172/75 Heading G1A Apparatus for sensing the deflection of a workpiece surface 5 resulting from accoustic energy applied thereto comprises laser 1 whose beam 9 after reflection from surface 5 is split by beamsplitter 2 into portions 9a, 9b which positionally coincideon sensor 7, portion 9b being delayed due to the distance 11. Surface 5 is subjected to accoustic energy at 1 to 10 Hz. The strength of the signal from photo-cell 7 depends on the phase difference of 9a to 9b, which varies according to the deflection of surface 9 during the delay time. For the phase difference over the photo-cell of diameter d to be constant, the angle between portions 9a and 9b at the photo-cells <#/2/d. For this the distance from surface 5 to splitter 2 is at least 5S for a diameter of 1 cm, or a telescope lens system with an aperture at the common focal point is interposed between 5 and 2 or mirror 10 and 2. The delay path may be folded by a pair of facing mirrors. Length S may be modualted Piezoelectrically at a frequency f 1  higher than the accoustic frequency f 2 , so that the optimum path period occurs several times within the vibration period and the photo-cell output is at frequency f 1  modulated by f 2 . The broken lines of Fig. 6 show the light beam of a second interferometer used to maintain a constant length S. If the distance of the delay path S via mirrors 2a, 18a, 18b and 2b alters, illumination at photo-cell 19 alters, giving a signal via amplifier 20 and filter 21 to Piezo-electric element 24a  causing the motion of mirrors 24b to restore the illumination of photo-cell 19. Alternatively S may be kept constant by the Piezo-electric means moving mirror 18 relative to a fixed reference.

Abstract: A computer system and associated method for executing a plurality of threads of execution with reduced memory space requirements. The computer system comprises a memory, an execution controller, and a data compressor. The execution controller controls execution of the threads such that the threads are executable and unexecutable at different times. The execution controller also stores uncompressed into available space in the run-time memory execution data of the threads when the execution data is generated. The data compressor compresses the uncompressed execution data of compressible ones of the threads that are unexecutable. As a result, space is made available in the run-time memory. The data compressor also decompresses in available space in the run-time memory the compressed execution data of decompressible ones of the threads so that the decompressible ones of the threads may be executed after becoming executable.

Abstract: PURPOSE:To decrease the scale and increase the speed by dividing a digital signal of a speech and a musical sound into plural bands through a band-pass filter group, and sampling the respective band digital signals down to a Nyquist rate and then performing adaptive conversion and encoding. CONSTITUTION:The speech and musical sound signal is divided by the low-pass filter 1 and high-pass filter 2 and made into a sampling signal of 8KHz through down samplers 3 and 4, and the signal is stored in buffers 5 and 6 in the form of blocks of 32msec; and ATC encoders 7 and 8 perform the adaptive conversion and encoding. The data signals of the low and high bands and auxiliary information are multiplexed by a multiplexer 11 and sent out to a transmission channel. In the band division encoding, complex arithmetic points of one block are halved in number from 2N=512 at the time of 16KHz sampling to N=256 and the complex arithmetic quantity of one block is therefore halved from Nlog2N to 2X(NX2)log2(N/2).
