  • Patent number: 4400940
    Abstract: A resonant type apparatus for absorbing wave energy arranged at wave-breaking facilities, which comprises, a caisson having a bottom plate, side plates, a backside plate and a top plate at least a part of which is omitted. A water chamber in the caisson has a length in a directional parallel to the side walls which is larger than 1/4 of the wave length Lc of a stationary wave within the water chamber, and a node of the stationary wave in the water chamber is formed at a distance Lc/4 from the backside plate. A pendulum is arranged at the position of the node of the stationary wave for swinging with a natural period Tp which is substantially the same value as the natural period Tw of the stationary wave, whereby the pendulum is swung by the stationary wave to absorb and convert wave energy to useful available energy at high efficiency.

  • Patent number: 4402009
    Abstract: Apparatus for enhancing incomplete, limited bandwidth, sequential signals generated by an image sensor. Each of the incomplete signals comprises a plurality of alternate lines containing information, the lines interposed therebetween being blanked. A picture display device is also provided, and an intermediate storage device interposed between the image sensor and the display device. The storage device stores a first of the incomplete image signals and combines it with the next sequential image signal to form a complete image signal. The complete image sgnal, which is displayed on the display device, contains the information in the next incomplete image signal on alternate lines, the lines therebetween containing the information in the first incomplete image signal. The invention also constitutes a method for enhancing incomplete limited bandwidth sequential signals wherein a first of these signals is stored and then combined with the next sequential image signal to form the complete image signal.

  • Patent number: 4400183
    Abstract: Process for separating the noble fission gases xenon and krypton from a prepurified waste gas from a nuclear plant. The prepurified waste gas is brought into contact with liquid Cl.sub.2 CF.sub.2 as an absorption agent in a first column at an operating pressure which is less than or equal to normal pressure, whereby Xe, Kr, N.sub.2 O, CO.sub.2, O.sub.2 and N.sub.2 are absorbed by the agent. Subsequently, the liquid absorption agent containing the absorbed gases is heated to substantially the boiling temperature of Cl.sub.2 CF.sub.2 at the operating pressure for vaporizing part of the liquid absorption agent and desorbing the absorbed Kr, N.sub.2 and O.sub.2 to thereby separate the Kr and Xe from one another. The desorbed Kr, N.sub.2 and O.sub.2 gases are separated from the vaporized absorption agent. The liquid absorption agent which has not been vaporized is treated to recover Xe, N.sub.2 O and CO.sub.2. Waste gas containing Kr, N.sub.2 and O.sub.

  • Patent number: 4400630
    Abstract: A frequency multiplier uses a pair of Schottky diodes to rectify an applied signal, with the rectified waveforms provided by both diodes being combined to produce an output signal having a predominant frequency of twice the applied frequency. In order to prevent distortion occuring at low signal levels, a d.c. bias is applied to the diodes so as to bias them at their threshold values. The effect of temperature variations on the diodes is minimized by using a further diode to determine the effective value of the bias voltage.

  • Patent number: 4400621
    Abstract: A device for simultaneously detecting alpha and beta particles which comprises a detector element, amplification means coupled to the output of the detector element and measuring means coupled to the output of the amplification means. The alpha and beta particles which impinge on the detector element exhibit different ionization densities, and this results in a voltage being generated at the output of the amplification means which has a rise time and amplitude corresponding to the type of particle impinging on the detector element. The measuring means measures at least the rise time of the voltage at the output of the amplification means, the rise time being different for the alpha and beta particles and providing a means for distinguishing between the two types of particles.
