Abstract: A highly sensitive chemiluminescent indicator system is disclosed for determining the presence or amount of an analyte in a liquid sample. The new acid optimum chemiluminescent indicator system comprises haloperoxidase (halide:hydrogen peroxide oxidoreductase), halide, oxidant and chemiluminigenic substrate. The indicator system acts as a synthesizer of highly reactive singlet molecular oxygen (¹O₂), which reacts with the chemiluminigenic substrate to yield an excited state, oxidized reaction product. The excited state reaction product then relaxes to a lower energy (e.g., ground) state with the emission of measurable light in an amount related to the amount of each of the reaction participants present in a reaction solution. Known, non-rate limiting amounts of three of the reaction participants are provided in an assay solution to determine the presence or amount of the fourth participant in a test sample. The fourth participant in the test sample may be the analyte of interest, or may be produced or consumed in the test sample through one or more preliminary reactions involving the ultimate analyte of interest, with the amount of the fourth participant being related to the amount of analyte in the test solution. Accordingly, the indicator system of the invention may be employed for the determination of a wide variety of analytes. The indicator system operates most efficiently over the range from acid to slightly basic pH, e.g., at a pH of about 3 to about 8. Also described is a variety of illustrative assay formats in which the indicator reaction of the invention may be employed, as well as kits for use in carrying out assays utilizing the haloperoxidase/halide/oxidant/substrate indicator system.

Abstract: An ink jet recording head is disclosed, in which a vibrating element includes electrodes 2,3, disposed on both surfaces of at least one of its edge portions at a dot forming pitch. A gap forming member is disposed so as to form a gap suitable for producing ink mist on a surface confronting a vibrating surface of the vibrating element. Since the ink is retained in this gap by surface tension, upon application of an alternate voltage to the vibrating element to produce an edge-mode vibration, the vibration produced at a piezoelectric body substrate 1 is transmitted to the ink, propagating through the ink. The vibration propagated up to an interface between the ink and the air is transformed into a surface wave, thereby misting the ink. 
     The thus produced ink mist, having vibrational kinetic energy, splashes in the air and thus forms a dot on a recording sheet. Since the amount of ink adhering to the recording sheet is proportional to an ink mist producing time, the optical density of a dot can be adjusted by controlling the alternate voltage application time.

Abstract: An optical disk 10 has groups of features (such as depressed areas) arranged in a servo pattern disposed in a plurality of circumferentially spaced sectors, and with a flat, non-grooved surface inbetween. Each even sector 15b includes a plurality of features formed in an arrangement which is the complement and/or reversal in order circumferentially of their arrangement in the intervening odd sectors 15a. A single photodetector 36 senses the change in amplitude of reflected light as a spot from a laser passes over one of the features and generates position sensing signals corresponding to the pattern. At least three phases of the position sensing signal are generated for each sector. Each phase is determined by edges on the disk offset circumferentially with respect to each other and separated radially from each other by a critical distance. Errors caused by variations in pattern size and/or radial velocity of an optical head as it moves generally radially of the disk are reduced.

Abstract: Test elements for use in clinical analyzers are usually assembled from a number of components which have fairly complex shapes and then bonded together using ultrasonic welding techniques. This requires careful assembly to provide adequate bonding. Described herein is a novel slide test element (10) and a method of its manufacture. The test element (10) comprises a frame member (20) having a recess (32) in which is retained a reaction member (12). An overhanging lip (34) is formed in a sidewall of the recess (32) to hold the reaction member (12) in position once assembled. Assembly is achieved by bending the frame member (20) with the lip (34) facing outwardly, forcing it to part a distance sufficient to allow the reaction member (12) to be inserted, and then relaxing the frame member (20) once the reaction member (12) has been inserted.
