Publication number: 20110222651Abstract: There is provided an inverter circuit which allows a single drive circuit to carry out both the tracking control for tracking resonance frequency fluctuations caused by load fluctuations, and the power control, thereby reducing switching loss. An inverter drive circuit part obtains a phase difference between output current and output voltage directed to a load circuit which is connected to a midpoint of two arm circuits of the inverter circuit, and controls a phase of the driving signal directed to each of the semiconductor switches in such a manner that the phase difference becomes zero or a predetermined value. This allows an operating frequency of the inverter circuit part to track a resonance frequency of the load circuit. In addition, this enables a current phase to be delayed with respect to a voltage phase, thereby achieving ZCS.Type: ApplicationFiled: November 5, 2009Publication date: September 15, 2011Applicants: HITACHI MEDICAL CORPORATION, Institute of National Colleges of Technology, Japan, National University Corporation Nagaoka University of TechnologyInventors: Mina Ogawa, Itaru Ando, Kiyoshi Ohishi, Shoutaro Shindo

Patent number: 7736941Abstract: In a light or radiation detector manufacturing method and a light or radiation detector of this invention, when forming a semiconductor, the semiconductor is formed in a predetermined thickness on a dummy substrate by vapor deposition, subsequently the dummy substrate is replaced with a graphite substrate which is a supporting substrate, and the semiconductor continues to be formed on the graphite substrate by vapor deposition. The time when forming the semiconductor in the predetermined thickness on the dummy substrate by vapor deposition is an initial state, and a defective film inevitably to be formed is formed on the dummy substrate. Subsequently, a semiconductor not in the initial state is formed on the graphite substrate put as replacement. This realizes a detector having the semiconductor of higher quality than in the prior art. The semiconductor manufactured in this way is formed continuously at least in a direction of thickness.Type: GrantFiled: April 12, 2007Date of Patent: June 15, 2010Assignees: Shimadzu Corporation, Institute of National Colleges of Technology, JapanInventors: Satoshi Tokuda, Tamotsu Okamoto
