Abstract: An object of the present invention is to construct a sensing system capable of extracting change information as new time series information from a continuous moving picture in a non-contact manner and remotely without requiring a special illuminating and irradiating device and driving the succeeding processing system as required, to clearly show a phenomenon in an arbitrary frequency band existing in the moving picture.

Abstract: An electric therapeutic apparatus for inducing an expectoration of sputum by a patient having difficulty therewith by using an interference low frequency wave, which comprises at least one electric current generating unit for generating an electric current having an intermediate frequency, an electric current detecting unit for detecting an electric current when an electric power is supplied, an electric current controlling unit for controlling the current flowing in the apparatus when an electric power is supplied, and at least one pair of electrodes adapted to be attached to a human body, the input of which is connected to the current generating unit.

Abstract: A porous membrane which is composed of cellulose acetate and acrylic polymer, for example, poly(methyl methacrylate) or methyl acrylate-methyl methacrylate copolymer, is highly suitable for plasmapheresis. A polymer alloy consisting of cellulose acetate, acrylic polymer and a small amount of cellulose nitrate has a good spinnability to produce a hollow fiber type membrane and has an excellent biocompatibility.

Abstract: A method for heat sterilizing an artificial kidney comprising a receptacle having accommodated therein permselective hollow filaments and including inlet and outlet ports for the blood and inlet and outlet ports for a dialyzate, which comprises(a) filling a primer consisting of water or a water solution into the artificial kidney,(b) connecting a pressure buffer tank to at least one of the inlet and outlet ports,(c) sealing the remaining ports by stopper means,(d) heating the artificial kidney to a temperature of 80.degree. to 130.degree. C. to heat sterilize it, and moving the gas and a part of the primer in the artificial kidney which have been expanded by heating to the pressure buffer tank,(e) cooling the artificial kidney to return the primer in the buffer tank to the artificial kidney, and(f) aseptically sealing the port connected to the pressure buffer tank; and artificial kidneys of specified constituent elements suitable for use in heat sterilization by this method.

Abstract: An electronic metronome with an oscillator for producing a signal of predetermined frequency and a variable divider connected to the oscillator for variably dividing the signal to a signal of lower frequency equal to that of a tempo sound to be obtained. A tempo sound generator is connected to the variable divider and is responsive thereto for generating the tempo sound to be obtained. Apparatus is provided for audibly and/or optically displaying the thusly obtained tempo sound. The electronic metronome is capable of effecting audible and visual display of a down-beat sound and medial-beat sound or any combination thereof besides the tempo sound.

Abstract: A divider for an electronic timepiece comprises a multistage divider circuit having a plurality of 1/2 dividing stages connected in cascade. Logic circuitry connected to the first and last stages develops a preselected number of pulse signals smaller in number than the dividing number of the divider circuit to effect selective stopping of the counting of only one input signal pulse applied to the divider circuit to thereby obtain fine adjustment of the final output signal pulses.
