A modulation method for a pulse width modulator in the inverter section (11) of a frequency converter provided with a voltage intermediate circuit, said frequency converter comprising a single-phase mains bridge (10) to be connected to a single-phase alternating current source (U L , N), a direct-voltage intermediate circuit and a controlled load bridge (11) for feeding a three-phase alternating v...

The door has two posts supporting a shaft (2) that winds a screen (3). An intermediate band (5) is coupled to the shaft by a groove (4) to continuously distribute force and to the screen by reversible connections to facilitate dismounting/mounting of the screen. The screen always forms a round turn on the shaft even when the screen is unwound and closes the door. The screen has two tapes and suppo...

A sonotrode has a circular blade (1) attached to it. A sonotrode disc (5) is attached to the sonotrode body, and the outer circumference of the disc forms the weld seam. Radial oscillations are exerted on the blade and the cutting edge of the blade extends over the outer circumference in the radial direction. The sonotrode body is rotationally symmetric, and the sonotrode has a rotational drive. ...

An ink jet head is provided with heaters to generate energy to be utilized for discharging ink, and MOS transistors to supply electric power to the heaters for recording by discharging ink. For this ink jet head, the MOS transistors comprise source regions and drain regions formed by doping layers arranged near the surface of a semiconductor substrate, gates formed on the semiconductor substrate t...

A television set includes an integrated receiver decoder. By integrating the receiver/decoder with the television, some circuitry and memory are shared. Moreover, a digital video signal provided by the receiver/decoder need not be converted to an analog NTSC signal before transmission to the television CRT. In one embodiment, where a television having a 16x9 aspect ratio is used, on-screen display...

The read-write system for optical discs [AT] has a laser diode [LD] output directed through an optical splitter [PBS] and a lens system [CL,WL,OL], and onto the disc. The optical signals are reflected back from tracks on the disc. The nature of the reflected signals will depend upon the depth of the tracks [F1,F2], which are dependent upon the type of recording. The optical signals are reflected t...

A method is provided to automatically determine a structure cancelled image in a dual energy decomposition system. A high energy and a low energy level image of internal anatomy formed of at least first and second types of structure are acquired. A characteristic mask is computed using a gradient mask and a localization mask. A first cancellation parameter is evaluated against the characteristic m...
