Title: Voice signal transmitting system of voice conference
Inventor: UENO NORIO
IPC: H04S1/00
Filed: 1982-03-31
Abstract: PURPOSE:To transmit a voice signal for conference without extending the band, by synthesizing the voice signal of left and right channels after separating the band at a comb type filter and transmitting the result from a single transmission line. CONSTITUTION:Left and right channel voice signals from microphones 13AR, 13AL having directivity of a conference room A are impressed to the 1st comb type filter 22R and the 2nd comb type filter 22L via band pass filters 21R, 21L. The signals are separated for the band of right and left 4-channel at the filters 22R, 22L and synthesized at an adder 23. The right and left channel voice signals synthesized are digitized at a coder 24 and transmitted to a transmission line 15. The reception signal from the transmission line 15 is analog-converted at a coder 24, the band is split at comb type filters 26R, 26L and outputted as voice from speakers 14BR, 14BL of a conference room B through LPFs 27R, 27L. Thus, the voice of right and left channels is transmitted via a public line.

Title: Inverter device
Inventor: YAMAMOTO TOUMA
IPC: H02M7/493
Filed: 1991-03-15
Abstract: PURPOSE:To control a higher harmonic cross current so that a value of the higher harmonic current flowing between a plurality of inverters may be within an allowable value by allowing an inverter installed separately from the plurality of inverters to supply an adjustiment voltage between the paralelly operated inverters according to the value of the higher harmonic cross currnet. CONSTITUTION:A higher harmonic current  IIH is allowed to flow between inverters 1A and 1B and is supplied to an inverter 500 through an amplifying circuit 702 and a PWN modulation circuit 703. The inverter 500 generates a voltage of fifteenth harmonic or thereabout in a moment and a switching filter takes away only a switching frequency component from the voltage and then such voltage is supplied between the inverters 1A and 1B by a transformer 503. Meanwhile, an effective value of the higher harmonic cross current IIH is detected by an effective value detecting circuit 704 and is deprived of a ripple component by a lowpass filter 705 and then is inputted into a gain selection circuit 706. The gain K is adjusted by the gain selection circuit 706 to increase when the higher harmonic cross current  IIH is equal to an allowable value or above while it is adjusted to decrease when the higher harmonic cross current I is smaller than the allowable value.

Filed: 1984-03-19
Abstract: PURPOSE:To attain highly reliable and safe control by replacing an uncertain factor included in causal relation between a manipulated variable and a controlled variable by the error variation of the manipulated variable and considering the uncertain factor of disturbance also as the error variation. CONSTITUTION:It is defined that the formula I is formed as a formula expressing the causal relation between the controlled variable and the manipulated variable of a process. When it is supposed that respective factors gi of disturbance Gt are varied within a range giL<=gi<=giH, the respective factors of a forecasting value Yt+1 of the controlled variable may be included within a range yiL<=yi<=yiH. If the limitation of Li<=yi<=Hi is applied to respective factors of the controlled variable Yt, the controlled variable Xt is proper when Li<=yiL and yiH<=Hi. If yiL<Li or Hi<yiH is applied to any one of factors of the forecasting value Yt+1, it is decided that the propriety of the controlled variable Xt is low.

Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To generate an output signal denoting an initial Huffman coding rate by storing pluralities of digital sets in a received digital signal, relating indicators, and coupling and storing them selectively. SOLUTION: The utilization and execution of this invention are realized by a software. Pluralities of digital sets in a received digital signal are not specific. Each digital set is stored in relation to an indicator denoting a generation probability of the digital set in the received digital signal (605). A variable memory storage space is used for an accumulator to denote the initial coding rate and initialized (702). When pluralities of relating indicators are stored (703), the related indicators are sequenced (704) and two indicators denoting a minimum generation probability are coupled selectively (705) and the result is added to the accumulator (706), and the processing continues to the step 703. When only a sole indicator is decided to be left (703), the initial coding rate is generated (707).

Title: Image data processor
Inventor: ABE SUSUMU
IPC: H04N1/413
Filed: 1984-03-16
Abstract: PURPOSE:To apply decoding processing efficiently to a compressed data by clearing an image memory before the decoding of the compressed data so as to prevent write of a specific dot to the image memory. CONSTITUTION:The image memory 5 is cleared by using an image memory clear circuit 6 ahead the decoding. When the clearing of the image memory 5 is finished, the main scanning address and the sub-scanning address is cleared next and the compressed code is converted into the dot pattern by a decoding circuit 4. In writing the dot pattern to the image memory 5, since the image memory 5 is cleared at first, the white run length is processed simply by having only to shift the address of the main scanning by the signal's share. In case of the black run length, the data is written normally to the image memory 5 and when the EOL is detected by repeating it, the subscanning address is incremented by 1 and the similar write is conducted at the next scanning line.
