Title: Power converter
Inventor: KOIKE MASATOSHI
IPC: H02M7/493
Filed: 1993-10-19
Abstract: PURPOSE:To provide a power converter which can quickly response to the abrupt change of a system voltage and prevent the occurrence of an overcurrent when an accident., etc., occurs in a system and the system voltage abruptly changes and can suppress the output of an unbalanced or harmonic component when the system is in a steady state. CONSTITUTION:Filters 17 and 18 input the detected voltage of a system through a three-phase/dq axis converter 5. Switches 22 and 23 output either the outputs of the filters 17 and 18 or the output signal of the converter which is the detected voltage of the system. Comparators 19 and 20 compare the output signal of the converter 5 which is the detected voltage of the system with the output signals of the filters 17 and 18 and control the switches 22 and 23 on the basis of the compared results. Therefore, not only the waveform of this power converter during the steady time, but also the response of the power converter when an accident, etc., occurs can be improved.

Title: Dma control method/device for information processor
Inventor: TAKAHASHI MASAKATSU
IPC: G06F13/362
Filed: 1992-09-30
Abstract: PURPOSE:To shorten the sampling cycle of a DMA request signal for improve ment of the working efficiency and to ensure the continuous DMA to a single request signal. CONSTITUTION:A circuit of a K channel processes K pieces of DMA request signals at the most. These request signals pass through an input circuit 2 and are latched by a latch circuit 3 as long as an inhibition signal is absent. If plural request signals are simultaneously latched, a selection circuit 4 selects the request signal of the highest priority. A latch circuit 5 latches the signals which are selected in the phases different from the circuit 3 and outputs a DMA signal. An output circuit 6 outputs an acknowledge signal and an inhibition signal so far as a DMA signal is outputted from either channel. Then a DMA cycle is started. An input circuit 2 receives the inhibition signal to cut off other request signals and also sends the DMA signal to the circuit 3. Thus the DMA cycle continues until the end of the transfer of data. The sampling cycles of both circuits 3 and 5 can be reduced less than the smallest bus cycle of a bus master.

Abstract: PURPOSE:To prevent an inner circuit element from malfunction due to the variation of a power supply voltage without forming a terminal for the input of a control signal at the variation of the power supply voltage by forming plural power supply voltage detecting circuits and clock selecting circuits, etc. CONSTITUTION:When the power supply voltage Vdd becomes the 1st lower limit reference voltage Vs or less at the drop of the Vdd, the 1st power supply voltage detecting circuit 12 detects the state and generates a clock generation stop signal (a). consequently, a clock selecting circuit 28 selects a low frequency, a program counter 16 stops its operation and an invalid instruction signal is outputted from an instruction decoder 18. When the voltage Vdd is dropped down to the lower limit reference voltage Vr or less, the 2nd power supply voltage detecting circuit 13 detects the state and generates a reset signal (b), so that a microcontroller is initialized. Since the circuits 12, 13, etc. are formed, the inner circuit element can be prevented from the malfunction due to the inner variation of the power supply voltage without forming the terminal for the control signal input at the variation of the power supply voltage.

Filed: 1991-10-09
Abstract: PURPOSE:To realize an automatic cutter function by performing 'post-mounting' or 'outer-mounting' on a facsimile device provided with an only manual cutter by driving a cutter mechanism based on the reception data outputted from a V21 modem by a cutter driving circuit at the time of a reception. CONSTITUTION:The data via an interface circuit 11 becomes the reception data of a V21 modem 12. The data demodulated in the V21 modem is passed to a V21 data decoding circuit 13. The demodulation data is 1 or 0 digital data. When an incoming is detected, a cutter 17 is initialized and the reception of a page end signal is monitored. This is performed by monitoring whether an FOP is received or not. Next, it is turned on the monitoring of the termination of a page print. As for this, since a delay exists between the reception of the page end signal and the termination of the page print, it is coped with. When the termination of the page print is detected, a cutter 17 is driven via a cutter driving signal generator 15 and a cutter driving circuit 16. Whether the reception is continued or not is checked. If the reception is not continued, the cutter is kept a standy state.
