Title: Air conditioning method by circulation and exhaust for gas to be treated and equipment therefor
Inventor: OTAKE NOBUYOSHI
IPC: F24F3/16
Filed: 1991-10-05
Abstract: PURPOSE:To make an air conditioning system efficient and energy-saving by normally air-conditioning the room in a state of low breakthrough rate under the prescribed temp. and heating a filter to above the prescribed temp. at appropriate intervals to desorb the adsorbed gas. CONSTITUTION:When a heating means 9 is controlled to W a state of low breakthrough rate at about <=600 deg.C and a fan 12 is operated, gas to be treated in a room 1 is sucked to inside an lower room 5 of a housing 2, causing coarse fine particles to be removed first by a prefilter 8. After that, the gas to be treated goes to the side of a partition 3 and sucked in a filter 13 through the fan 12 to adsorb it. Then the cleaned air is returned to the room 1 by a circulating duct 6. After the above cycle is performed for a certain time, when a controller 16 raises the temp. of the heating means 9 to >=60 deg.C to open an exhaust diverter valve 15, breakthrough is accelerated, causing gas accumulated in the filter 1 3 to be discharged to the atmospheric side. Thus effective air- conditioning is performed.

Title: Projection exposure device
Inventor: KATO KINYA
IPC: G02B7/28
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To perform a projection exposure process always at a proper imaging performance by adjusting a focusing condition under the monitor of the intensity of leak light. SOLUTION: A part of exposure light is transmitted through a plane reflecting mirror 4 after the exposure light is incident thereon. The exposure light through the plane reflecting mirror 4, or leak light is detected with a photo detector 11, and the output signal thereof is fed to a control system 22. Then, the control system 22 refers to a data table 21 showing a relation between the quantity of the leak light and the fluctuation amount of the focal point position of a projection optical system. The control system 22 thereby finds the fluctuation amount of the focal point position of the projection optical system, depending on the output signal of the photo detector 11.  Also, the control system 22 feeds a drive signal to a drive system 23, on the basis of the focal point position fluctuation amount so found and moves a stage 103 or even a plate 102 by the required amount in a Z-axis direction, depending on the drive signal. Thus, the focused condition of a mask 101 and the plate 102 relative to the projection optical system can be adjusted for the focal point position fluctuation of the projection optical system attributable to the exposure light absorption of a positive lens 3.
