Abstract: A receiver, in operation, receives a PHY layer Data Unit that includes a duration field, the duration field including duration information that indicates a duration of time during which the communication apparatus is prohibited from transmitting a high efficiency (HE) trigger-based (TB) PHY layer Data Unit. Physical (PHY) layer circuitry in operation, issues a PHY-CCA (clear channel assessment) primitive parameter. Media Access Control (MAC) circuitry in operation, updates a Network Allocation Vector (NAV) value based on the duration information when the indicated duration is greater than a current NAV value and when it is determined that the communication apparatus is not a targeted recipient of the received PHY layer Data Unit. The MAC circuitry in operation, determines busy/idle state of at least one subchannel. The MAC circuitry, in operation, controls transmission of the HE TB PHY layer Data Unit.

An energy stored in the primary winding of the high-tension transformer is released through the closed circuit. A high-voltage output induced in the secondary winding (T 2 ) of the high-tension transformer is applied to the X-ray tube through a second rectifier circuit (DB 2 ). A voltage applied to the X-ray tube (XT) is detected at a voltage detection circuit (2) and controlled in the feedback control circuit (3). Control signals are supplied to the respective arms of the bridge inverter so that the voltage to be applied to the X-ray tube becomes a predetermined value.

Abstract: In this circuit, an ohmic resistance (7) is necessary for the required formation of the base current between the secondary winding (5) of the driver transformer (3) and the base of the line output stage transistor (8). This resistance (7) can be omitted due to the fact that the equivalent resistance of the secondary winding (5) is dimensioned to be correspondingly large. The same wire is preferably used for the primary winding (4) and the secondary winding (5) of the driver transformer (3). This considerably simplifies the automatic fabrication of the driver transformer (3). <IMAGE>
