摘要： A capsule-type medical apparatus holds a drug such that a drug release such as dissolution can be realized under the same condition as in a case where the drug is delivered to an interior of a living body by itself, and realizes confirmation on whether the drug delivered to the interior of the living body is actually released to a site in the living body or not. The capsule-type medical apparatus includes a capsule-like casing which is formed in a suitable size for insertion into the living body, a net-like drug holding unit which houses a drug in a releasable manner with respect to a site in the living body, and an imaging unit which captures an image covering the drug held in the drug holding unit and a surrounding area of the drug. The imaging unit 4 captures an image as drug-source information indicating a release condition of the drug with respect to the site in the living body.

摘要： When an ECU receives a transmission signal having a high level from a transmission, the ECU exerts torque reduction control to reduce a torque control value for a motor generator. Furthermore the ECU sets an optimum (or target) value of a voltage as based on the torque control value and a motor rotation speed and controls an upconverter. Herein, when the transmission is shifting gears, the ECU controls the upconverter to allow the voltage to be constant regardless of whether the torque reduction control is exerted to reduce the torque control value.
