Abstract: A half-wave dipole antenna (10) is arranged on one side (19) of a single printed circuit board (20) of the radio set, in addition to the electronic circuits. This antenna (10) has two arms (11, 12) which are of equal length and are arranged on the edge (25) of the board. One arm (11) is connected to a matching line (15) which is composed of printed, high-impedance microstrip lines (17.1, 17,2) and discrete capacitors (18.1, 18.2) and its impedance is matched to the input impedance of the antenna (10). Arranged on the other side (21) of the board (20) is a large-area earth surface (22) which, in an assigned manner, covers the region of the matching line (15) and leaves the region of the antenna arms (11, 12) uncovered. To this end, the surface (22) terminates with a relatively sharp end (23). The second arm (12) is connected to this end (23) through the board (20), and is thus earthed. <IMAGE>

Abstract: The apparatus for operating a discharge lamp in the present invention can easily set the lighting efficiency of each of all discharge lamps at a given value by decreasing the crest factors of the discharge lamps to a given level or lower, and narrowing the variance between the crest factors. Pulse current output from the diode circuit (16) is supplied to the inverter circuit (20) via the partial smoothing circuit (18), where the current is converted into a high-frequency current. The high-frequency is further changed to a high voltage by the resonance circuit (20), and the high voltage is supplied to the discharge lamps (26₁, 26₂) via choke coils (L0₁, L0₂) to light the lamps. The discharge lamps (26₁, 26₂) are connected in common to the resonance circuit (22) only, and therefore the crest factors of the lamps can be commonly adjusted by the value of each of the coil (L12) and capacitor (C15) of the resonance circuit (22). Thus, the variance of the crest factors of the discharge lamps can be narrowed, and the crest factors can be easily decreased to a given level or lower.

Abstract: In a continuous casting process for steel, a molten core inside a strand is stalled at a specific point Q in a pass line of the strand to form a cored portion including no molten steel in the strand downstream of the specific point Q, and the cored portion is rolled by a pair of rolls under pressing into a solid strand in the latter half of a strand drawing stroke. The resulting solid strand comprises a skin formed of a chill crystal and the interior formed of a columnar crystal by addition of proper casting temperature. A through continuous casting/rolling process in which the above improved continuous casting process is combined with a subsequent hot rolling process is also disclosed. A drastic increase in the casting efficiency, an improvement in quality, and an equipment capable of freely adjusting a casting thickness can be resulted so that direct coupling between continuous casting and rolling is achieved and near-net-shaping of various steel materials is promoted.

A winding (170) is connected at one end between the switches and is connected at the other end at a center-tap of two power capacitors (162,164) connected in series across the bus. The position of the rotor is sensed by a Hall device (182) and the speed or torque of the motor is controlled by selectively gating the switches to apply current through the winding so that the windings generate a magnetic field for rotating the rotor at a desired speed or torque. A voltage doubler, Cuk dc/dc converter, or other regulating device may be used to power the motor. The stator may have removable asymmetric teeth tips to permit efficient winding and avoid the motor parking at a zero torque starting position.
