Title: Stowage method of powdery material
Inventor: IMOTO HIROMI
IPC: B65G3/02
Filed: 1984-04-09
Abstract: PURPOSE:To secure the homogeneity of ingredients by dissolving the heterogeneous tendency of the ingredients in the pile width direction when a bedding pile is disburse with a double-wheel type reclaimer. CONSTITUTION:A specific ore S is stowed so that a virtual stowage reference pattern PL is formed in the center of the specific ore layer S. In discharging the specific ore with a double-wheel type reclaimer, as soon as the scrape-up quantity F(x) of a specific ore on the right half PN of the pile by a wheel H2 starts gradually decreasing, the scrape-up of the specific ore on the left half PM of the pile by a wheel H1 starts, thus quite the same quantities are disbursed as shown in the disbursement quantity F(x) pattern, i.e., the homogeneity of ingredients can be realized and the heterogeneity can be prevented.

Title: Coding device for character information
Inventor: KUDO SHOZO
IPC: G06K9/00
Filed: 1985-04-05
Abstract: PURPOSE:To attain efficient transmission or input of even picture information including an illegible character by providing a means for applying compression coding to a part not recognized by a recognizing means in input picture information as picture element data. CONSTITUTION:A picture element data converting section 20 applies compression coding to dot data read from a page memory 16 and its output is sent to a formatter 34 via a picture element memory 26. In this case, the data not read as a character in the data data of a designated range of an original 10 stored in a memory 16 is commanded to be subjected to compression coding as the picture element data by a control section 48 to the converting section 20. The conversion section 20, based on the said command, reads the data commanded by the memory 16 and applies compression coding and outputs the result to the formatter 34 via the memory 26. Picture data and character code data are built into a transmission format by the formatters 34, 38 and outputted via a synthesis section 44. Thus, even the picture information including an illegible character is sent or inputted efficiently.

Filed: 1979-06-07
Abstract: PURPOSE:To cancel an input-side leakage current accurately by setting a resistance, constituting feedback paths for scale-factor determination and leakage-current cancellation, to a value meeting specific requirements. CONSTITUTION:Between the negative-input terminal and output terminal OUT of operational amplifier OPA, and its input terminal and earth terminal, resistances R1 and R2 are connected respectively to form a feedback path for scale-factor determination; and between the positive input terminal of OPA and the earth, resistances Rf and RB are connected in series and between the connection point between the both and terminal OUT, resistance RA is further connected to form a feedback circuit for leakage-current cancellation. In this case, amplification factor A of OPA is greater than one and its input is differential, so that leakage currents of the same polarity and size will appear at the positive and negative sides. Therefore, the leakage currents are canceled without reference to the magnitude of an input voltage by setting their resistance values satisfying that RA/RB=R1/R2 and Rf=RB(R1-RA)/(R1+RB), increasing input impedance viewed from terminal IN.
