摘要： According to the invention, the grains of the hydrate slurry are separated by sedimentation where the dispersed bubbles of air are removed in course of the presizing, then a supplementary sizing is carried out. Preferably, a liquid free from hydrate grains is fed in to stream against the sinking grains. This liquid is advantageously the spent liquor of the hydrate filter. The apparatus according to the invention consists of a container with conical bottom, a feeding device, a slurry outlet stub and an overflow channel. The inlet stubs of the feeding device, however, are placed off-center and every stub is connected with a presizing equipment. This equipment is composed of a bundle of pipes and/or a pack of plates which are slop placed to geometrical axis: At the upper part of the presizing equipment there is a foam overflow apparatus. The bottom of each presizing equipment is connected with a common cone-frustum type deflector casing. The casing is concentric with the container. There is ring shape gap between the upper edge of the deflector casing and the cylinder jacket of the container. Under the deflector casing there is an upwards convex control cone. The control cone is vertically adjustable and concentric with the deflector casing.

摘要： A method for determining charged energy states of a sample of a semiconductor or insulator material by using deep level transient spectroscopy. The method includes the steps of exciting the sample by application of periodical exciting pulses to change the initial charge state, detecting the transient response of the sample when it returns to the thermodynamical balance condition following the termination of each of the excitation pulses, blocking the detection during a blocking period defined as the combined existence of the exciting pulses and of a dead period including the recovery period of the means used for the detection, performing a weighted integration operation on a detected response signal by the application of a symmetrical square wave synchronizing pulse as a weighting function synchronized to the frequency of said exciting pulses, blocking the detection in each of said detecting periods for the duration of a further blocking period which begins in a moment defined between the starting moments of the two exciting pulses immediately preceding and following said detecting period and synchronizing the synchronizing pulses to terminating moments of said dead periods to have a period time which is equal to the period time of said periodical exciting pulses. Apparatus for carrying out the method is also disclosed.

摘要： A Deep Level Transient Spectroscopy (DLTS) method in which a high frequency measuring signal is applied continuously on a semiconductor junction, and exciting pulses are generated which are coupled through fast semiconductor switching elements to the junction to alternatively bias the junction in reverse and forward (or slightly reverse) directions. The high frequency measuring signal passed through the junction is evaluated by means of a lock-in amplifier phase-locked with a constant phase angle, independent of the repetition rate of the exciting pulses.The evaluation circuits of the apparatus including the lock-in amplifier are controlled by switching elements driven by control signals generated from the exciting pulses.
