Abstract: An apparatus for measuring fluorescence lifetime includes a pulse laser source that generates a pulse excitation light, a detector that detects a fluorescence generated from a sample by irradiating the pulse excitation light, and outputs a detection signal corresponding to the fluorescence, a measurement unit that measures number of photons emitted in a predetermined time gate based on the detection signal, a correction unit that corrects the number of photons measured based on Poisson distribution, and a calculation unit that calculates the fluorescence lifetime of the sample based on the number of photons corrected.

Abstract: A fluorescence lifetime measurement apparatus includes a first controller controlling a total gate length and a second controller controlling a start gate length of a plurality of gate lengths into which the total gate length is divided. The start gate length is a time window whose start time is when measurement of the number of fluorescence photons of a specimen starts. The apparatus also includes a measurer measuring the number of fluorescence photons for each of the gate lengths; a processor calculating a fluorescence lifetime the specimen based on the start gate length and the number of fluorescence photons; and a third controller causing, when the fluorescence lifetime does not satisfy a predetermined condition, the first and second controllers to change the start gate length and the total gate length.

Abstract: In one antenna unit, a non-electrically conductive resin layer is provided on a core portion of electrically conductive material and a winding portion is configured by a coil wound on the layer. The antenna unit is housed in a band attaching portion of a watch case of a watch, and a watch module is housed in the watch case. In another antenna unit, a core portion and a winding portion wound on the core portion are arranged in a cover case. Openings are formed in side walls of the cover case oppositely positioned to each other, and parts of the outer circumferential surface of the winding portion are arranged in the openings. The winding portion together with the core portion is supported to the inner surface of the cover case by adhesive portions interposed between the cover case and the winding portion.

Abstract: An antenna includes an elongate laminated core, a core case having an electrical insulating property and housing the core, and a coil wound around the core between both end portions of the core through the case. The core has a first and second groups, each including thin plates of amorphous soft magnetic alloy laminated with each other, and is configured by stacking the first and second groups one another. Each of the thin plates of the core includes flanges provided at both end portions thereof, and a coil wound portion between the both end portions, and the case includes projections, which push the both end portions of the thin plates of the second group to separate from the both end portions of the thin plates of the first group in the laminating direction of the thin plates of the core while the core is housed in the case.

Abstract: Motors are driven to sequentially move a fixed mirror from an origin or a current position thereby to measure amplitudes of a laser fringe by a photo detector. When a signal satisfying a reference value is obtained at some position, amplitudes are measured on a circle around the position as a center. A point having the largest amplitude among all the measured points on the circle is set as the center of a next circle and so the similar measurement is repeated until the amplitude at the center of a circle becomes maximum among all the measured points on the circle. When the amplitude at the center of the circle becomes maximum among all the measured points on the circle, the motors are driven so that phase differences of a vertical side signal and a horizontal side signal from a reference signal approach a target phase difference.
