Title: Picture processor
Inventor: HOSOKAWA HIROSHI
IPC: H04N1/40
Filed: 1988-03-04
Abstract: PURPOSE:To attain a correct image area separation by deciding an image area by using a concentration comparison in a picture element block and a concentration comparison in an average value block constituted of the concentration average value of a picture element block. CONSTITUTION:A first detecting means 4 detects the maximum value and minimum value concerning block picture data composed of an (m)X(n) picture element. A first image area discriminating means 5 obtains the difference value of the maximum value and the minimum value detected, and by comparing the obtained difference value and a first prescribed threshold, discriminates whether the block picture data belong to a photograph picture area or not. An arithmetic means 6 obtains the average data concerning block picture data. A second detecting means 7 detects the maximum value and the minimum value concerning the block average data composed of obtained MXN blocks. A second image area discriminating means 8 obtains the difference value in the detected maximum value and minimum value, and by comparing the obtained difference value and a second prescribed value, discriminates whether the block average data belong to the network point picture area or not. Thus, the image area can be correctly separated.

Title: Circuit for improving short-circuit capability of igbt
Inventor: PELLY BRIAN R
IPC: H02M7/537
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To attain an increase of short-circuit capability of IGBT(insulated gate bipolar transistor), by providing a common emitter resistor in series to the high efficiency IGBT. SOLUTION: In a high gain high efficiency IGBT, a common emitter resistor R is additionally provided. In this way, by voltage Isc×R directly subtracted from effective gate emitter voltage, an effective gain at short-circuiting time is decreased. For instance, in the case of additionally providing the 33 mωcommon emitter resistor R in the IGBT of 1600 V high gain high efficiency type, an ordinary working current=12 A rms, an ordinary working current of R=8.4 A rms, an ordinary working loss of R=8.4<2> ×0.033=2.3 W. Here, an estimated loss in the IGBT at 12A output time, in a frequency 4 kHz, is 13.5 W, and a loss in R is 17.6%. From this point of view in the IGBT of 600 V rated high efficiency type, a loss projected in the common emitter resistor at full load time, in the common emitter resistor presenting 10 microsecond short-circuitting time, is understood to be in the range of 13/17.5% in the IGBT loss.

Abstract: PURPOSE:To improve the limit of stability measurement which is limited by a rounding error by counting the rise of the output signal of an oscillator which outputs an electric signal of frequency higher than the frequency of an input signal. CONSTITUTION:The input signal Sa is detected by a detector 1 and converted into a rectangular wave signal Sb of the same repetitive frequency fi, whose rise is counted by a counting timing signal generator 6 and corresponds to the integer multiple of the period of the signal Sa; and a latch signal Sc is outputted every time the rise is counted by (n) corresponding to the minimum time unit of the integration of set Erlang variance measurement. Further, the signal SR of frequency fR higher than the frequency fi of the signal Sa is outputted by the oscillator 8 separately, counted and cumulated continuously by a counter 5, and latched in a latch circuit 7 with the signal Sc. The counted value of this counter 5 is stored in a memory 3 every time the latch is updated. Then a data processing part 4 calculates the Erlang variance from the memory contents with the data processing start signal Sd of a measurement data counter 9 which counts the signal Sc.
