Part of the air dried by removing moisture is decompressed through a passage 7 and a throttle valve 11, and it is fed into an adsorption tower 4' for a regenerating step to purge tower 4'. Each of the adsorption towers 4, 4' is provided with a magnetron 15 and a waveguide 16, and the adsorbent 5' in the adsorption tower 4' is irradiated with microwaves during the regenerating step. In the regenerating step, water is desorbed from the adsorbent 5' and air rich in moisture is discharged to the outside of the system through a valve 10 and a passage 12. By the irradiation of microwaves, the lowering of the temperature in the adsorption tower during the regenerating step can be prevented, and the recirculated amount of dry air required for the regeneration is not changed even when an adsorption-regeneration cycle is repeated.

Title: Automotive power window control method and device
Inventor: KAWAMURA YOSHIHIRO
IPC: E05F15/16
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To control the opening or closing of a windowpane by simply backing up the drive of a windowpane on-off power source motor at the time of something wrong with a microcomputer, correspondingly to each making state of both manual and automatic control switches opening or closing the windowpane of each individual door of a car body. SOLUTION: In this control method, a switch moving contact 12 is selectively switched to both pull-up and pull-down fixed contacts 13 and 14 for connection to each other, whereby a windowpane is pull-upped and pull-downed for opening or closing. When a pulse signal out of a pulse output terminal 24 of a microcomputer body 20 is in such frequencies as being out of the setting range, a watchdog timer 30 judges that the microcomputer body 20 is in trouble, and thereby this microcomputer body 20 is reset by an Lo level judging signal out of a judging signal output terminal 32, and then it is inputted into a base of a transistor Tr3 of a backup circuit 60 and a bias (constant voltage or current) is added.  Correspondingly to a state that the switch moving contact 12 is connected to both the pull-up or pull-down fixed contacts 13 and 14, a motor M is rotated and driven in either direction of both normal and reverse rotations by switching action due to the backup transistor Tr3 and two relay driving transistors Tr1 and Tr2, and thus all windowpanes are controlled for their on-off operations.
