Patent number: 10395766Abstract: Upon evaluation of a value of a diagnostic process, the value of a diagnostic process is evaluated not based on a simple cost but on a cost required for all processes of a patient who was in the diagnostic process through a follow-up survey. Diagnostic processes that are not relevant to a target diagnostic process are eliminated, clustering is performed on patients to divide the patients into clinically meaningful homogeneous groups, and the target diagnostic process is evaluated for each of the homogeneous groups. For the purpose, importance scores of data pieces of the clinical data are calculated and the relevant data is output using the output result of the medical knowledge extraction unit, clustering is performed on patients in the clinical data, and a clinical index and a cost are output for each of the clusters.Type: GrantFiled: June 28, 2013Date of Patent: August 27, 2019Assignee: Hitachi, Ltd.Inventors: Syuntaro Yui, Kunihiko Kido, Kazuyuki Shimada, Masayuki Ohta, Jumpei Sato, Toru Hisamitsu

Patent number: 9634203Abstract: A light emitting device includes: a substrate having a main surface; a phosphor layer provided on the main surface and containing an LED element that emits primary light and a fluorescent particle that absorbs a part of the primary light and emits secondary light; and a transparent resin layer having a refractive index n and covering the phosphor layer. The transparent resin layer has an outer circumferential surface that forms a boundary between the transparent resin layer and the atmosphere. When a minimum circumference that includes the overall phosphor layer and is concentric with the outer circumferential surface has a radius r in a cut surface where at least a part of the outer circumferential surface takes a shape of an arc having a radius R, a relationship of R>r·n is satisfied. With such configuration, the light extraction efficiency is enhanced.Type: GrantFiled: May 29, 2009Date of Patent: April 25, 2017Assignee: SHARP KABUSHIKI KAISHAInventors: Shin Ito, Yutaka Okada, Takanobu Matsuo, Masayuki Ohta
