Abstract: A photon counting device includes a plurality of pixels each including a photoelectric conversion element configured to convert input light to charge, and an amplifier configured to amplify the charge converted by the photoelectric conversion element and convert the charge to a voltage, an A/D converter configured to convert the voltages output from the amplifiers of the plurality of pixels to digital values; and a conversion unit configured to convert the digital value output from the A/D converter to the number of photons by referring to reference data, for each of the plurality of pixels, and the reference data is created based on a gain and an offset value for each of the plurality of pixels.

Abstract: A winding reel which can be placed on another similar free winding reel so that they can be stored or carried in a comparatively small space and is convenient to carry or handle. The winding reel includes a hollow core section, and first and second flange sections provided at the opposite ends of the core section. The core section includes four core wire pieces extending in an axial direction thereof. The first flange section includes a first flange wire piece extending radially outwardly from a first end of each of the core wire pieces in a plane perpendicular to the axis and a connection wire piece for connecting outer ends of adjacent ones of the first flange wire pieces. The second flange section includes a second flange wire piece extending radially outwardly from a second end of each of the core wire pieces in a plane perpendicular to the axis and a third flange wire piece extending radially inwardly from the second end of each of the core wire pieces in the plane perpendicular to the axis.

Abstract: A therapeutic agent for the treatment of psychomotor excitement containing as an active ingredient of L- or DL-erythro-3-(3,4-dihydroxyphenyl)-serine with or without a decarboxylase inhibitor.

Abstract: A chain link plate including a pair of enlarged end parts joined by an intermediate constricted part. Each end part has an opening therethrough. The link plate is symmetrical about a first axis which extends longitudinally of the link plate and passes through the centers of the openings. The link plate is also symmetrical about a second axis which extends perpendicular to the first axis and perpendicular to the axes of the openings. Each end part has a convex curved exterior edge surface generated about a first radius which is centered on the first axis. The intermediate constricted part has upper and lower concave curved exterior edge surfaces each defined about a second radius which is generated about a center point located in sidewardly spaced relationship from the link plate. The second radius is equal to the first radius.

Abstract: A method of blanking wherein an endless V-shaped groove of desired contour is formed on at least one of the top and bottom sides of a material sheet. The groove is shaped so that the external side thereof is at a right angle to the groove-cut surface of the sheet. A blank having the desired contour is then cut out of the sheet along the right-angled external side of the groove.
