Abstract: A semiconductor substrate in includes a buffer layer and a first crystalline layer. A bandgap of the first crystalline layer is smaller than a bandgap of a second layer. When a semiconductor wafer is formed as a transistor wafer, a channel of a transistor is formed at or near an interface between the first crystalline layer and the second layer. With a first electrode and a second electrode provided and a third electrode provided, when space charge redistribution, for emitting electrons and holes from a bandgap of a crystal positioned in the spatial region, is achieved by applying negative voltage to the third electrode or by applying positive voltage to the second electrode with the first electrode serving as a reference, an electron emission speed in the space charge redistribution is higher than a hole emission speed.

Abstract: A medical practice operation assistance terminal according to the present invention comprises a medical practice acquisition unit which is capable of transmitting an acquisition request of a medical practice to a data base storing information relating to medical practice(s), and acquiring the medical practice(s) related to the acquisition request; a judgment unit comparing identifier of the readout item of a medical practice and identifier of the item specified among the displayed items of the acquired medical practice(s); and an acquisition decision maker unit for deciding whether or not the medical practice acquisition unit is to be activated with the specified item as a search condition in accordance with a category of the specified item constituting the medical practice, if a readout identifier information identifies with the identifier information of the specified item.

Abstract: A hospital information system according to the present invention lets an RF reader 12 comprised by a PDA 8 read tag information, once for all, recorded by RF tags either attached to, or embedded in, plural kinds of a plurality of patient wrist bands, injection medicine bottles, patient charts, medical instrument cases, et cetera, and transmits a query to a server 5 by way of a wireless LAN 9, server 7 and LAN 3 for confirmation from the server 5. The server 5 collates it with the content of a medical practice order recorded in its data base, and registers a completion of instructed operation for an instructed item in the database, as well as responds back with notifying “correct” if the transmitted readout data from the PDA 8 is correct. If the readout data is not correct, the PDA will be notified of “incorrect” with an instruction for reading again.

Abstract: A hospital information system for managing clinical path information constituted of a plurality of medical service information each indicating a schedule regarding a medical service for a patient, comprising: an obtaining unit for obtaining the clinical path information; a converting unit for converting the clinical path information into medical service notification information for notifying the medical service information to a medical department linked to the medical service in accordance with the medical service information; and a transmitting unit for transmitting the medical service notification information to the medical department.

Abstract: An information system for use in a hospital includes a mobile terminal for inputting and outputting data relating to medical activities at an execution site of the medical activities in the hospital, a hospital information management system for managing information in the hospital, and a server for controlling communications of data relating to medical activities between the mobile terminal and the hospital information management system.
