A device comprises tuyeres at the bottom of the converter and a cylindrical manifold for fluids and powdered products disposed in the center part of and under the bottom of the converter. Connecting pipes between the manifold and the tuyeres are disposed radially around the manifold. The connecting pipes have the shape of a lyre with a closed loop.

A converter includes a voltage selector which employs IGFETs as voltage switching elements, and a controller which controls the IGFETs. Each of the IGFETs in the voltage selector is made either the P-channel type or the N-channel type, depending upon a voltage level to be thereby switched and a level of a binary signal supplied from the controller. As a result, a voltage of comparatively great level can be switched by a binary signal of small level amplitude.

According to this invention, a converter includes a voltage transformer, a switching transistor, a resistor, a control transistor, and a control circuit. The voltage transformer has a primary winding, a secondary winding, and a control winding. The switching transistor is connected in series with the primary winding. The resistor is connected between the switching transistor and one terminal of an input power source. The control transistor has a base connected to a connection point between the r...

A power converting apparatus and method comprising a transformer and converting circuit mounted with the transformer for converting direct current to a series of pulses in the primary winding which includes a pulse train forming an effective current with reciprocal positive and negative sine wave components for each half cycle of chosen frequency. A gating circuit is mounted with the transformer for sequentially passing the pulses in the positive sine wave components followed by the pulses in th...

An auxiliary lens with which lenses are held within a mount has an afocal magnification of 0.8 and serves as a wide-angle conversion lens when attached to the front face of a taking lens with a small aperture. On the other hand, when attached to the front face of a taking lens with a large aperture, the auxiliary lens serves as a ratio conversion lens for an aspect ratio switchable camera which can switch an aspect ratio of the imaging area from 16:9 to 4:3.

An analog-to-digital or digital-to-analog converter comprises: a signal input terminal an integrator connected to the signal input terminal; a plurality of constant current sources connected to the integrator so that the integrator is supplied with respective constant currents; a first counter having a first predetermined number of bits for higher significant bits and a second counter having a second predetermined number of bits for lower significant bits; and a clock signal generator for genera...

A converter including a tiltable body, a mantle ring spaced from the converter body, supportable in support lugs and having a rectangular cross-section with upper and lower flanges, and lamella suspensions and body guides for connecting the mantle ring with the converter body, with the lamella suspension including a lamella pair having one of its opposite ends releasably secured to a first attachment bracket connected to the lower flange of the mantle ring, and having another of its opposite end...

A converter converts a DC voltage U.sub.Bat into an output direct voltage U.sub.out, in particular in TV or computer screens. The converter includes a full-bridge circuit for chopping the DC voltage U.sub.Bar into an AC voltage U.about. on its output and a switching circuit for converting the AC voltage U.about. into the output direct voltage U.sub.out of the converter. The converter further includes a control circuit for generating control signals to drive controllable switching elements in the...

This invention relates to a converter and, in particular, to an improved converter including a cast bottom having an inserting groove, two connection cylinders, a trough stand, two ribs and an isolation trough, a cast top, a receptacle stand, a L-shaped fixing bracket a receptacle and a transformer. The trough stand of the cast bottom will prevent resin poured in to secure a transformer in place from flowing randomly, and confine it in the trough stand so that wires, connection cylinders, the fi...
