Title: Air purifier
Inventor: HANADA EIICHIRO
IPC: B01D53/32
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To prevent the spread of fire from spark discharge in corona discharge electrodes to a dust collecting filter by arranging a dust collecting filter, corona discharge electrodes and a gas treating functional material from the upstream side of a wind flow and arranging the dust collecting filter and the gas treating functional material almost parallel to hold a partition plate between them. SOLUTION: Air introduced into a device main body 11 passes through a prefilter 15 and a dust collecting filter 16 to remove dust and then reaches corona discharge electrodes 21. On the corona discharge electrodes 21, plasma, free radicals and ozone are produced and a part of odorous component in the air is reacted with the produced plasma, free radicals and ozone to be deodorized. After a part of the residue is adsorbed to the surface of a gas treating functional material 23, is reacted with plasma, free radicals and ozone to be deodorized. In this case, the air passing through the dust collecting filter 16 flows around the edge of the partition plate 19 and reaches the corona discharge electrodes 21. Thus, when the dust is ignited by the spark discharge of the corona discharge electrodes 21, the spread of fire to the dust collecting filter 16 can be prevented.

Title: Printed board unit version number managing method
Inventor: TSUCHIYA HIDEAKI
IPC: G06F13/14
Filed: 1989-05-29
Abstract: PURPOSE:To surely recognize a version number by displaying the version number information of a printed board unit by cutting one of plural patterns at every modification of the printed board unit, and informing the version number information to a processor. CONSTITUTION:Circuit change is performed when the modification of the printed board unit 1 is requested, however, since modification data for a current printed board unit can be automatically generated by computer design based on the circuit change, modification is performed based on the modification data, then, the cutting of the pattern 13 is executed. A version number delivery means 12 sends a positive logic value to the terminal 17 of a connector since ground potential supplied from the pattern 13 disappears by cutting the pattern 13. In such a way, the processor monitoring the output signals of the terminals 17-20 recognizes the printed board unit as a first version judging from the fact that the terminal 17 is provided with the positive logic value and the terminals 18-20 with negative logic values. Also, the fact that the printed board unit 1 is the first version is recognized visually.
