Abstract: In a stage member for use in an exposure apparatus, a honeycomb structural body has walls that are extended in a direction perpendicular to a longitudinal direction of the stage member and that surround square shaped prismatic spaces, so as to accomplish a high resistance and a high resonant frequency with respect to torsional vibration. The honeycomb structural body of the stage member is preferably made of a ceramic material.

Abstract: Mount terminals (32-34) formed on the end faces of a housing (31) in the longitudinal direction respectively abut against external electrodes (1, 2) which are formed on an end face of a piezoelectric element (6) in the longitudinal direction and used to apply input voltage, and an external electrode (3) for extracting output voltage. These abutted portions are fixed by soldering or with conductive adhesive to electrically connect the mount terminals to the external electrodes and fix the piezoelectric element (6) inside the housing (31).

Abstract: In a piezoelectric transformer device (36), a plurality of inner electrodes are stacked on each other on the left side. These inner electrodes are alternately connected to each other through interlevel connection conductors to constitute two inner electrode groups. A secondary output electrode in the form of a mesh is formed near the end portion of the device (36) on the right side. Only primary input electrodes (1,2) connected to the two inner electrode groups, a secondary output electrode (40), and the lead electrode of the secondary output electrode in the form of a mesh are exposed on the same surface of the device.

Abstract: A herbicidal composition which comprises as the active ingredients (a) 2-[7-floro-3,4-dihydro-3-oxo-4-(2-propynyl) -2H-1,4-benzooxazin-6-yl]-4,5,6,7-tetrahydro-1H-isoindol-1,3 (2H)-dione and (b) N-methoxymethyl-2',6'-diethyl-2-chloroacetanilide or 2-chloro-'6-ethyl-N-(2-methoxy-1-methylethyl)Acet-O-toluidide and an inert carrier or diluent, which exerts a synergistically enhanced herbicidal potency.
