Abstract: The continuous oven for baking planar works according to the present invention comprises an oven main body, a work lifting unit for conveying works upward inside the oven main body in a sequential manner; a work lowering unit for conveying works downward inside the oven main body in a sequential manner; whereby the works are baked while being conveyed by the work lifting and lowering units in a substantially vertical direction. Thus, the works are conveyed vertically most of the time during the stay in the oven, and the floor space area necessary for the installation of the continuous oven can be therefore minimized. In particular, by arranging the works one over the other, typically in a mutually spaced relationship, in the work lifting and lowering units, it is possible to minimize the dead space inside the oven.

Abstract: The present invention provides a process for eliminating effectively ATP in a sample, using adenosine phosphate deaminase alone or in combination with at least one enzyme selected from the group consisting of apyrase, alkaline phosphatase, acid phosphatase, hexokinase and adenosine triphosphatase, a process for determining biological cells contained in foods and beverages in convenient and precise manner in combination with bioluminescence method, and a reagent for the determination thereof.

Abstract: An apparatus for conveying a wafer to wafer work suction-holding stage and then discharging a worked wafer from the wafer work suction-holding stage, including a loader side elevator device, a wafer position correcting stage, a wafer work suction-holding stage, a wafer carrying table and an unloader side elevator device which are successively disposed in this order; and the apparatus further including a conveyor which conveys a wafer inside a loader side magazine carried on the loader side elevator device to a point above the positional correction suction-holding stage, a stopper which positions the wafer conveyed by the conveyor to the wafer position correcting stage, and a feeding pawl moving device which operates after the wafer position correcting stage and wafer work suction-holding stage have been moved vertically so that the upper surface of the wafer position correcting stage is at substantially the same height as the upper surface of the stopper and so that the upper surface of the wafer work suction

Abstract: In a baking oven for baking a relatively planar work such as semiconductor substrates, LCD panels and integrated circuit boards, a laterally elongated slot is formed in a shutter door which is moveable in the vertical direction. The oven main body is internally provided with a rack having a plurality of shelves which are each associated with the slot of the shutter door in such a manner that the work supported by each of the shelves of the rack may be aligned with the slot of the shutter door by appropriately determining the vertical position of the shutter door. Thus, by minimizing the area of the access opening of the oven main body, not only the loss of energy is minimized but also undesirable fluctuations in the internal temperature of the oven main body is minimized.

Abstract: Fluorogenic compounds are disclosed which are reactive with biologically important analytes including primary amines, secondary amines, and/or thiols and are of the general formula: ##STR1## wherein X is a group such as ##STR2## --CN, --CO.sub.2 CH.sub.3, or SO.sub.2 R, and wherein R is OR.sub.3, or Cl; R.sub.1 and R.sub.2 are hydrogen atoms or alkyl groups having 1 to 3 carbon atoms and R.sub.3 is a phenyl or benzyl group. The inventive compounds form a fluorescent adduct with the above analytes at the number 7 position of the benzoxadiazole ring. The fluorescent adduct thereby formed enables detection of very minute amounts of analyte (picomoles) using conventional fluorescent analytical methods.

Abstract: Disclosure herein is novel oxalic acid ester derivatives represented by the general formula: ##STR1## wherein either one of X and Y represents a nitro group, and the other represents ##STR2## in which R represents a lower alkyl group, and n represents a figure of 1-50. The oxalic acid ester derivatives are useful as chemiluminescent reagents for fluororescent substances.

Abstract: An antenna apparatus has a first wire-like antenna element formed into a rectangular planar loop and a second antenna element which comprises two L-shaped plates electrically connected to the loop and mounted to a rectangular planar base member. The loop is hinged to the planar base member along long sides of the respective rectangles so that the angle between the planes of the loop and base member is adjustable. The base member pivots about an axis on a mount which can be secured to a television receiver.

Abstract: A method for detecting fluorescent materials in liquid chromatography. Fluorescent materials are excited by chemical reaction with chemical reagents to yield light (chemiluminescence) and detected at high sensitivity. The detection apparatus is composed of a mixer for mixing a solution containing separated fluorescent materials and solutions of chemical reagents to afford chemiluminescence, a flow cell and a light receptive detection means for detecting the light thus produced.
