Abstract: A manually adjustable display device for displaying information. The display device includes a frame containing a plurality of designated grooves; a plurality of side segments each including a display side and a non-display side disposed on an opposite side of the display side; a center segment including a display side and a non-display side disposed on an opposite side of the display side of the center segment; and a plurality of suspension members for suspending the side segments and the center segments in the designated grooves so that the side segments and the center segments can rotated within the designated grooves to display either the display or the non-display side of the segments.

Abstract: A particle analyzing system for a clean room smock includes a mannequin corresponding to the shape of a human body and having a clean room smock placed thereon. A gas supply apparatus is connected to the mannequin, and is operative to discharge a gas at a first set of sites on the mannequin. A particle supply apparatus is connected to the mannequin, and is operative to discharge particles at a second set of sites on the mannequin.

Abstract: The present invention relates to a manufacturing method of granulated complex molecular sieve composition having multifunction and useful for removal agent of harmful gas of cigarette or treatment agent of water purification etc. as having multifunctioned adsorption capacity and excellent anti-abrasion property, and convenient process, in particular, to a manufacturing method which is comprised of granulating by mixing alkali metal silicate aqueous solution to mixture of zeolites of various types and active carbon and treating it with water solution of alkali earth metal salt without calcination, and drying.

Abstract: An air current guiding apparatus includes a plurality of dampers installed on a filter unit on an inner wall of air supply unit for blowing clean air over wafers loaded in a boat for transfer to a reaction chamber for chemical vapor deposition. Each of the dampers has a certain length and angular orientation to force the air in a designated direction so that the air current in a wafer loading chamber maintains an appropriate velocity and is free from air turbulence, thereby minimizing the number of contaminating particles in the wafer loading chamber.
