Title: Original feed roller of copying machine
Inventor: MAEDA TERUO
IPC: B65H5/06
Filed: 1981-08-04
Abstract: PURPOSE:To prevent a copy from becoming unclear owing to the staining of an original, by using foamed chloropyrene rubber of the driven roller of a couple of original feed roller. CONSTITUTION:When an original P to be copied is conveyed by being sandwiched between a driving roller 1 and a driven roller 2 under specified pressure, pencil powder on the original written in pencil sticks to the driven roller 2 and is accumulated thereupon. For this purpose, the driven roller 2 is made of foamed chloropyrene rubber to reduce the dirtying of the driven roller as compared with a roller made of conventional polyurethane foam rubber, and therefore the staining of the original is reduced to obtain a clean copy.

Title: Exhaust gas purifying device for internal combustion engine
Inventor: TAKAHASHI TOSHIKATSU
IPC: F02D41/04
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust gas purifying device capable of precisely and quickly judging a completion time of NOx discharging from a NOx absorbent and maintaining excellent exhaust gas characteristics. SOLUTION: During reduction enriching for discharge of NOx from a NOx absorbent, a correction item DVO2REF is calculated (S21) according to an output VLAF from an air-fuel ratio sensor arranged in upper stream of the NOx absorbent. A fundamental reference value VO2REFO is corrected by the collection item DVO2REF, and a given reference value VO2REF is calculated (S22). The fundamental reference value VO2REF0 is an annealed value of the output VO2 of an oxygen concentration sensor arranged downstream from the NOx absorbent. When the output VO2 of an oxygen concentration sensor exceeds the given reference value VO2REF, it is decided that discharge of NOx is completed, reduction enriching is completed (S23, S26).

Whereupon, differential pulse BP appears in the output signal d of a differential circuit 6, and since the signal a is in high level, a processor 1 receives the differential pulse BP as an anomalous signal. The processor 1 stops the output of a motor-driving signal for a motor control circuit 3 and also makes the signal a a low level. Also, the processor 1 informs an operator of the occurrence of anomalous situation by using a displaying means, etc.
