摘要:
An ultrasound diagnostic apparatus for obtaining an ultrasound image of a subject into which an ultrasound contrast agent mainly composed of microbubbles is injected, comprising a probe configured to transmit/receive an ultrasound wave to/from the subject, a transmission circuit configured to drive the probe to transmit an ultrasound wave while sequentially changing a direction of an ultrasound transmission line, a reception circuit configured to generate reception line data of the number of parallel reception from ultrasound echo signals obtained by one ultrasound wave transmission, a transmission/reception control circuit configured to control the transmission and reception circuits to change the number of parallel reception during a scan sequence for generating a 1-frame ultrasound image, and an image processing unit configured to generate an ultrasound image on the basis of the reception line data.

The difference frequency component between a first fundamental wave of frequency f and a second fundamental wave of frequency f2 is caused to interact with a second harmonic wave, thereby to attain the enhancement of a second harmonic signal, etc., whereby a reflected wave component to be imaged is extracted at a high S/N ratio. By way of example, in a case where the difference frequency component is to appear on the lower frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=2.8 f or so. Besides, in a case where the difference frequency component is to appear on the higher frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=3.2 f or so.

A heat exchanger includes a core. The core includes a heat-exchange tube for a heat exchange medium to circulate therein. The core includes a fin joined to the heat-exchange tube. The heat exchanger includes a pair of header pipes connected with both ends of the core. Each of header pipes includes header pipe members. Each of header pipes has a joint member communicating with header pipe members. The joint member has communication holes arranged longitudinally of the header pipes at intervals.

A compound type heat exchanger has a core part including a plurality of heat exchanging pipes and fins juxtaposed and alternately stacked into a lamination. Header pipes are connected to both ends of the pipes. Partition walls are provided in the header pipes. At a boundary of the partition wall and a spatial part, the core part is divided into two parts providing an oil cooler unit on one hand and a condenser unit on the other hand. The spatial part is defined in the core part, corresponding to the intermediate portion between the partition walls in the header pipe. Owing to the provision of the spatial part in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.

A medical diagnosis system wherein a medical image is produced in a medical diagnosis apparatus, comprises a first storage device which stores an examination procedure for the medical diagnosis apparatus, a second storage device which stores supply information, a supply device which supplies the supply information stored in the second storage device, and a control processor which controls that the supply information is supplied in the supply device in accordance with the examination procedure stored in the first storage device.
摘要:
A compound type heat exchanger has a core part including a plurality of heat exchanging pipes and fins juxtaposed and alternately stacked into a lamination, in common. At both ends of the lamination in the longitudinal direction of the pipes, they are connected with header pipes. A pseudo heat exchanging passage member having a substantially Z-shaped section is arranged in place of a specified heat exchanging tube of the heat exchanging tubes and a fin adjoining the specified heat exchanging tube. The pseudo heat exchanging passage member is formed so as not to allow passage of the heat exchanging medium. At the boundary of the pseudo heat exchanging passage member, the core part is divided into two parts in the laminating direction, defining an oil cooler unit on one hand and a condenser unit on the other hand. Owing to the provision of the pseudo heat exchanging passage member in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.
