IPC: H01M4/62
Filed: 1979-11-30
Abstract: PURPOSE:To obtain a plate with a good conductivity as well as high mechanical strength without reducing the packing ability of the paste which is packed into a base body, by adding both water and sulfuric acid to an active material, kneading this mixture to make a paste, and cooling the paste before it is added with ice and kneaded again. CONSTITUTION:An active material such as lead powder, litharge or minium is added with both water and sulfuric acid, and this mixture is kneaded to make a paste, which is cooled by putting it into a kneading machine which is precooled to a temperature of -2--6 deg.C. Following that, pieces of crushed ice having a length of 1-20mu are poured into the former kneading machine, so that the ratio of the ice to the former lead powder becomes 2wt%. After that, the paste is kneaded again to make the ice to equally dispersed into the paste, thus obtaining another paste, which is packed into a lead-grid base plate.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce the processing time through simultaneous conduction of filter processing and data compression processing to improve image quality, to decrease the cost and to attain high performance by allowing a gain revision means to change a gain of a quantization means depending on an edge degree number. SOLUTION: Image data from a host device 200 are converted into bit map data and stored in a frame memory 102. The bit map data by one page expanded in the frame memory 102 are given to a block division section 103, where the data are divided into blocks of a prescribed size and the blocks are transferred to a Wavelet transform section 104. An edge degree calculation section 108 calculates a density gradient in a block based on data from the Wavelet transform section 104 and provides an output of the result to a gain revision section 109. The gain revision section 109 changes the gain of a quantization section 105 based on the density gradient. A quantization section 105 applies quantization processing to data from the Wavelet transform section 104 at a gain revised by the gain revision section 109 and transfers the result to a coding section 106.

Title: Device for detecting and correcting double bit error
Inventor: TOOMASU ETSUCHI HAUERU
IPC: H03M13/00
Filed: 1976-12-24
Abstract: Apparatus for directly decoding and correcting double-bit random errors per word and for detecting triple-bit errors per word is disclosed. Said apparatus comprises a syndrome calculator which operates upon codewords received from memory and generates syndromes. The syndromes are operated upon and translated by a mapping device which generates pointers identifying the bits which are in error. The pointers are then passed through decoding means to generate error words which are summed with the received word from memory to provide a corrected codeword. The syndrome calculator may further provide a parity check signal to determine if a three-bit error is present, in which case the decoding means are not enabled and a signal is generated indicating that a triple-bit error has been detected which is not correctable.

Filed: 1978-12-20
Abstract: PURPOSE:To make a fault diagnosis possible in a system operation state by generating a false input signal under no influence of the contact state of a plant, by internally providing a false input setting signal generating circuit. CONSTITUTION:Switch element 1a is turned OFF by check start signal 20. On the other hand, false input setting signal 19 from a computer is set to a logical signal level ''Low'' and switch elements 8 and 9 are turned OFF and ON respectively via gate elements 11-13. In this state, input voltage ei at an input signal reception terminal is OV regardless of states of contacts 3a-3n of a plant. Consequently, comparator circuits 1a-1n operate and gate elements 2a-2n output logical signal ''1'' to the computer. To perform operation equivalent to the turning-OFF of contacts 3a-3n, on the contrary, logic level ''HIGH'' is set to false input setting signal 19 from the computer. In this state elements 8 and 9 are ON and OFF respectively and voltage ei is +VB. Consequently, none of circuits 1a-1n operates and elements 2a-2n output signal 1.

Abstract: PURPOSE:To inexpensively miniaturize a driving device for liquid-crystal display device with a simple constitution without causing any decline in contrast, by providing a driving voltage control circuit which impressed a driving voltage across liquid crystal while effective data that are displayed in a liquid crystal panel are inputted and a quiescent voltage which is lower than a nonselected picture element driving voltage during the other period. CONSTITUTION:Voltages on a signal side and scan side are controlled by means of a driving voltage control circuit 105 so that a liquid crystal driving voltage can be impressed across a liquid-crystal panel 107 while any one of scanning side electrodes is in a selected state and a quiescent voltage which is lower than a nonselected picture element driving voltage can be impressed while all scanning side electrodes are in a nonselected state. If the numbers of the scanning lines and scanning electrodes of video signals 101 are n and M, respectively, the driving voltage of this time becomes (N/M)<1/2> times lower than the normal driving voltage. Since the impressing voltage is almost zero and the nonselected picture element driving voltage is not impressed during the quiescent voltage period in such way, the responding characteristic is decided by the driving voltage of the period, during which effective data are inputted, and the contrast does not decline.
