Title: Control circuit for switching type power converter
Inventor: WU CHIN-LI
IPC: H02M3/335
Filed: 2001-06-08
Granted: 2003-02-21
Abstract: A kind of control circuit suitable for use in a switching type power converter is disclosed in the present invention. The switching type power converter contains a rectification circuit, a transformer and its peripheral circuits, a DC output circuit, a controlled switching circuit, and a feedback circuit. The switching type power converter converts an AC power into a DC voltage to supply for a load. The control circuit contains the followings: an energy storage capacitor electrically and serially connected between a variable resistor and grounding point in the feedback circuit, in which the resistance value of the variable resistor is increased as the load voltage value is decreased and is decreased as the load voltage value is increased; the first voltage dividing resistor, which is electrically and serially connected between the variable resistor and the controlled switching circuit; the second voltage dividing resistor, which is electrically and serially connected between the first voltage dividing resistor and the grounding point; and a controlled switch, which is electrically connected among the controlled switching circuit, the first voltage dividing resistor and the grounding point. The controlled switch is turned-off as the total voltage value of the voltage dividing resistor is decreased when the resistance value of the variable resistor is increased due to the decrease of the load voltage value so as to enable the controlled switching circuit such that the operation of energy transformation between the transformer and its peripheral circuits is performed. The controlled switch is turned-on as the total voltage value of the voltage dividing resistor is increased when the resistance value of the variable resistor is decreased due to the increase of the load voltage value so as to disable the controlled switching circuit such that the operation of energy transformation between the transformer and its peripheral circuits is stopped.

Filed: 2001-10-12
Granted: 2003-09-21
Abstract: The present invention is related to driving circuit for an organic electroluminescent element, electronic equipment, and electro-optical device. The subject of the invention is to provide an organic electroluminescent element driving circuit to which a reverse-bias is applied without having neither substantial increase in power consumption nor increase in layout space. With the arrangement of switches 20-1 and 20-2, the electroluminescent elements are set to be in a reverse-bias state. The pixels are reverse-biased on the basis of a group of predetermined pixels at a time, for example, the pixels are reverse-biased on a pixel-by-pixel basis or on a line-by-line basis, or all pixels are reverse-biased at a time. In this way, reverse bias can be applied without the need for an additional power source, and with neither substantial increase in power consumption nor increase in layout space involved. The service life of the organic electroluminescent element can thus be prolonged.

Further, a first-order lag integral, calculated by subtracting a slip angle frequency omegas from the obtained deviation value omega'rest, is multiplied by a correction gain to obtain a correction amount. Then, an accurate estimated speed omega""rest may be obtained by correcting the estimated speed omegarest with the correction amount.

Title: Piezoelectrically driven printhead array
Inventor: DANTE HENRY M
IPC: B41J2/14
Filed: 2002-03-28
Granted: 2003-08-21
Abstract: A printhead includes a common ink chamber or reservoir bounded on one side by a membrane having nozzle apertures. The membrane forms a print face of the printhead. Piezoelectric elements (piezos) are located on the membrane near the nozzles. The piezos flex segments of the membrane surrounding the nozzles to eject ink droplets from the nozzle apertures. Ribs are also provided on the membrane and define boundaries of the membrane segments corresponding to the nozzles. The ribs can isolate each nozzle from the other nozzles, in two ways. First, the ribs act as stiffeners so that when piezos attached to one membrane segment flex that membrane segment, the other membrane segments are not significantly flexed. Second, when the ribs are provided on an interior surface of the membrane, they deflect the pressure pulse in the ink fluid from a flexing membrane segment, upwards, away from adjacent membrane segments/nozzles.
