Inventor: SCHWARZ STEFAN
IPC: G09G5/393
Filed: 1990-03-21
Abstract: A monitor control circuit serves to control a monitor whose display can be generated by reading out a digital video signal with a second pixel frequency from a video storage device, on the basis of a digital video signal having a first pixel frequency. For gap-free conversion of the first video signal to the second video signal, or for combining video signals of different graphics standards, the digital video signal of the first pixel frequency is read into a FIFO storage device (3) with a frequency dependent on the first pixel frequency and the data words of the digital video signal which are to be stored in the video storage device (4) are read out from the FIFO storage device (3) only during time segments in which no data are read out from the video storage device (4), whereby the number of data words which can be read out from the FIFO storage device (3) for storage in the video storage device (4) may vary. <IMAGE>

IPC: G01R19/165
Filed: 1992-06-06
Abstract: An electric induction motor (10) is coupled to a source (X, Y, Z) of alternating current by a thyristor switch (14). A control circuit (20) triggers the thyristor switch (14) to create conductive and non-conductive states during each cycle of the alternating current. A circuit (68) senses the voltage across the thyristor switch (14) during a non-conductive state. From that sensed voltage and known characteristics of the motor (10) being controlled, the control circuit (20) derives a measurement of the current flowing through the motor (10) in the conductive state of the thyristor switch (14). One of two different derivation techniques is used depending upon the length of the non-conductive state. The control circuit (20) includes a means (57) for calibrating the derivation of the current measurement for a specific motor.

Abstract: The invention relates to a method for operating a baking oven (which can be closed via a door) of a domestic cooker, grill or the like which can be heated by means of at least one electrical heating device and/or one microwave device, in the case of sole operation of the microwave device or in the case of combination operation of the microwave device with an electrical heating device, the microwave device being cut off when the door is opened. In order to render manual switching-on of the microwave device superfluous and in order to ensure that the operation of the microwave device is continued once the door has been closed if its operating duration has not yet elapsed, the microwave device in combination operation is automatically switched on again, according to the invention, when the door is closed again, after such microwave device has been cut off as a result of the door being opened, provided an adjustable time duration for microwave operation has not yet elapsed. <IMAGE>

Abstract: A new gene family induced by TGF-beta is disclosed. Two new genes, designated βIG-M1 and βIG-M2, are induced in response to TGF-β1 treatment of mouse embryo fibroblasts. These genes encode proteins containing about 345 to about 380 amino acid residues, with a molecular weight of about 37,000 to about 48,000 daltons and about 38 cysteine residues. The induced proteins share about 50% homology with each other and significant homology with a v-src induced protein in chicken embryo fibroblasts designated CEF-10. These proteins may be involved in producing some of the growth and differention modulating effects of TGF-β1.

Abstract: The oscillator comprises a plurality of differential amplication stages (10,12,14,16) each arranged to introduce a phase shift between its differential input signal and its differential output signal such that the total phase shift introduced by the stages is 360 o . In this way an oscillating signal is produced at the output of each stage. Because each stage receives and supplies difference signals, any changes in the power supply of the stages affect both inputs or outputs in the same way so that the effect on the differential signal is minimal. The circuit thus provides a reduction of the effect of power supply noise. The oscillator may be used for instance in a N-PLL-circuit.

Abstract: An apparatus provides digital data representative of a compressed high definition video image signal in a manner such that a conventional video tape recorder (VTR) employing current electrical and mechanical technologies is adaptable for reading this data for display in special modes such as fast forward, reverse and still frame. To minimize the loss of data while the VTR is operating in one of these special modes, the data representative of the high definition image signal is decoded by the apparatus to yield available time slots in the data stream. These time slots are then filled with data which duplicates the most important of the original transmitted data then existing in other time slots in the data stream. This duplicating of the data increases the likelihood that the important picture information will be read by the VTR while operating in a special mode. To facilitate fast recovery from lost of synchronization, the apparatus utilizes a small fraction of the original image which is included in each section or slice of the transmitted image. As synchronization is reacquired, the high definition video image is built from the image found in the slices.
