Abstract: There is provided an electric supercharger having a compressor including a compressor impeller, a motor housing, an electric motor rotationally driving the compressor, and a first bearing and a second bearing provided to support a shaft and a rotor in the motor housing. The first bearing is located on the compressor side of the rotor and the second bearing is located on the other side of the rotor. The motor housing includes a thermal conductive passage through which heat generated by a coil wound around a stator is transmitted to the first and second bearings. The thermal conductive passage between the coil and the first bearing is formed with a reduced thickness portion in such a way that thickness of the thermal conductive passage is reduced in a direction that is perpendicular to a direction in which the heat is transmitted through the thermal conductive passage.

Abstract: An electric supercharger includes an electric motor, a motor housing, a drive circuit, a circuit housing, and a compressing portion. The circuit housing includes an accommodating wall having a shape projecting from an outer surface of the motor housing, and a bottom located at a distal end in the projecting direction of the accommodating wall. The circuit housing together with the motor housing, hermetically confines the drive circuit. The bottom includes a heat release portion that faces the outer side of the circuit housing. The drive circuit is thermally coupled to an inner surface of the heat release portion that faces the inner side of circuit housing.

Abstract: An electric supercharger having an impeller that rotates in order to supercharge a fluid includes: a housing; a shaft supported to be capable of rotating relative to the housing via a first bearing and a second bearing; a first bearing sleeve and a second bearing sleeve fixed to the housing in order to support the first bearing and the second bearing, respectively; and a first rubber sheet and a second rubber sheet provided between the housing and the first bearing sleeve and the second bearing sleeve, respectively, in an axial direction X. With this electric supercharger configured in the abovementioned manner, elastic members can be incorporated easily between a housing and respective bearing sleeves, and an offset load can be prevented from acting on a pair of bearings supported by the respective bearing sleeves.

Abstract: In a digital scintillation camera system, image data representing an radioisotope distribution is detected by a scintillation camera and is then digitized and converted to a video signal. The video signal is processed in a video imager to produce a diagnostic image on a film. A count-to-grey-level converter is arranged to convert a radiation count of diagnostic image data to a grey-level. A count-to-grey-level conversion table is accessed in the converter. The conversion table includes a correction component for obtaining the same count-density characteristics of a film as in a conventional analog scintillation camera system.

Abstract: An emission computed tomography apparatus comprises a patient couch on which a subject on the dosage of rodioisotope (RI) lies and a two-dimensional position detector for collecting radioisotope distribution data in the subject at various rotation positions while rotating around the subject and the patient couch in order to obtain a tomogram image of the RI distribution in the subject. In order to eliminate a false image (artifact) on the tomogram image resulting form unequal detection characteristics in the position detector, the patient couch is traveled in one direction of the coordinate systems every time the position detector is rotated by a given angle. One position signal from the position detector is corrected in response to the traveling length of the patient couch. An artifact-free tomogram image of the RI distribution is obtained on the basis of the corrected position signal and another position signal from the position detector.
