Abstract: The present invention relates to a pulse charging method and charging system for use with non-aqueous secondary batteries, employing a pulse charge controlling method all the way from the start to the end of charging. This pulse charging method has an on-duty ratio of pulses in a next specified charge period reduced when an average battery voltage has exceeded a charge control voltage during a specified charge period, has an on-duty ratio of pulses in a next specified charge period increased when the average battery voltage has not exceeded the charge control voltage and has the pulse charging ended when an on-duty ratio of pulses has reached a specified value. The pulse charging system comprises an on-duty ratio reducing means for having an on-duty ratio of pulses reduced, an on-duty ratio increasing means for having an on-duty ratio increased and a means for determining pulse charge ending for having the pulse charging ended when an on-duty ratio of pulses has reached a specified value.

A control device calculates a wash water stream in a wash step and a period of the wash step in the washing operation by a neurocontrol in which data of the cloth volume, the cloth type, soil degree and soil type are supplied to a neural network as input data. The neurocontrol is compensated for in accordance with the turbidity of a wash liquid detected at the time of completion of the wash step.

Abstract: According to an image memory address assignment system, a frame memory is divided into a plurality of blocks. Upper bits of the address of the frame memory constitute a block address, and lower bits constitute an intrablock address. The block address is supplied to an address converter. The address converter has a conversion pattern ROM. The conversion pattern ROM stores conversion patterns each converting the input write address signal block address to a block address for a completely read block area so as to perform simultaneous read and write access even if the data read direction (order) of the frame memory is different from the data write direction. The address converter supplies the write block address to the frame memory. As a result, the data can be written in the completely read block.

Abstract: In a pattern data conversion processing system, one-character pattern data generated by a character generator is divided by a shift register into a plurality of basic pattern data. The divided basic pattern data are sequentially subjected to enlargement, 90.degree. conversion or nonrotational conversion by using a 4/3 times elongation conversion ROM, a double elongation/90.degree. conversion ROM and a bypass circuit. The converted one-character data is stored in a one-character ROM and, as such, the one-character pattern data from the one-character ROM is stored by a direct memory access controller (DMAC) into a frame memory. When 180.degree. conversion is designated, the one-character data is subjected to 90.degree. conversion, and the converted data is stored in the frame memory. The pattern data from the frame memory is transferred by the DMAC to a page printer which then prints the transferred data.
