Abstract: The converter utilises a MOSFET power transistor switch with its output electride coupled to a tuned network that operatively limits the voltage waveform across the power switch to periodic unipolar pulses. The transistor switch may be operated at a high radio frequency so that its drain to gate interelectrode capacitance is sufficient to comprise the sole oscilaltory sustaining feedback path of the converter. A reactive network which is inductive at the operating frequency couples the gate to source electrodes of the transistor switch and includes a variable capacitance as a means of adjusting the overall reactance, and hence the  converter's switching frequency in order to provide voltage regulation. The resonant rectifier includes a tuned circuit to shape the voltage waveform across the rectifying diodes as a time inverse of the power switch waveform.

Abstract: Apparatus has a rotary drum (1) provided with a heating jacket (12) therearound. The drum is mounted on a base (3) pivotally supported on a pedestal (2). The base (3) can be caused to take different orientations so as to enable the drum to take different attitudes. While the drum is in a vertical position, a mixture of fine particles and a liquid is supplied into the drum through a supply passage (27) formed axially in a rotary shaft (24) which extends into the drum rotatably and axially slidably relative to the drum. The mixture is filtered through a filter (21) disposed in the drum. Filter liquid is discharged to the outside. The particles are prevented from passing through the filter and remain in the drum. Thereafter, the particles are heated and dried by a heating jacket (12) on the drum while the drum is caused to assume a horizontal position and being rotated. The drum is then inclined such that the initially upwardly directed end thereof is directed obliquely downward. Thereafter, an agitating blade (25) and sweeping blades (26) on the inner end of the rotary shaft (24) is rotated and shifted axially, whereby the dried particles are agitated and swept, to be discharged to the outside.

Abstract: The target tracking system has high tracking reliability at small servo load and comprises a plural number of groups of target sensors having tracking signal travelling times which vary from one group to the other and defining respective lines of sight, a servo system causing the lines of sight to track the target, a target estimator for estimating the movement of the target, a servo estimator for estimating the movement of the servo system, and a regulator which identically controls the servo system and the servo estimator such that the vectorial difference between the estimate of the target movement and the estimate of the servo movement is caused to approach zero. During the target tracking operation, vectorial target deviation signals which are generated by groups of angle sensors, are processed by multipliers using respective matrices in order to produce related combined target deviation signals. The thus processed vectorial target deviation signals are directly applied to the servo system and the servo estimator in a manner as if there would be present only one respective angle sensor producing the combined target deviation signal.
