摘要:
A technology for structuring a three-dimensional image in a more accurate position spatially even when an ultrasonic transducer unit does not perform oscillation scanning at completely constant angular velocity is disclosed. According to the technology, an oscillation angle detection means 104 detects an oscillation angle of an ultrasonic transducer unit 1, and a three-dimensional image processing means 11 forms a three-dimensional image based on the oscillation angle detected by the oscillation angle detection means and image data outputted from an ultrasonic receiving means 4.

A technique for smoothly speed-controlling a speed of a motor whose time constant is relatively small, such as a supersonic motor, under a relatively rough speed control profile and a simple configuration is disclosed. According to this technique, a frequency division number calculating section 1 changes a division number A under the relatively rough speed control profile and sets for a frequency division number setting register 2. The comparator 3 outputs a+count signal if the division number A set by the frequency division number calculating section is greater than a current division number B counted by a frequency division number counter 4 (the division number A> the division number B), and outputs a—count signal if the division number A

An excellent ultrasonic diagnostic apparatus is provided that can form a three-dimensional image in a more spatially-correct position regardless of an ultrasonic probe to be used, without leading to deterioration of the productivity of the treatment. An ultrasonic probe includes an ultrasonic transducer, a rotation transmission mechanism, a rotary encoder, a transducer-swinging motor and an encoder correction ROM. In the encoder correction ROM, an actual swing scanning angle of the ultrasonic transducer with respect to each count value that is obtained by counting pulses from the rotary encoder is stored in advance. A three-dimensional image processing means forms a three-dimensional image of a principal cross-section scanning plane in a direction at the actual swing scanning angle, while correcting an encoder count value from an encoder counter according to contents of the encoder correction ROM that are read out by a main controlling means.

Provided are diphenyl sulfide derivatives which have excellent S1P3 antagonistic activity and are useful as drugs. Intensive studies have been made for the purpose of creating a compound having S1P3 antagonistic activity. As a result of the intensive studies, it has been found that diphenyl sulfide derivatives represented by general formula (1) have excellent S1P3 antagonistic activity. In general formula (1), R1 is a hydrogen atom or the like; R2 is an optionally substituted alkyl group having 1 to 6 carbon atoms, or the like; X is a methylene group which may be substituted with one or two fluorine atoms, or the like; Y is a hydrogen atom or the like; and Z is a halogen atom.

A solid state image sensing device has a photoelectric transfer section for transducing incident light into signal charges, at least firs% and second charge transfer paths, a charge transferring section for transferring the signal charges from the photoelectric transfer section to the first path at a first timing and for transferring the signal charges transferred to the first path to the second path at a second timing and a charge supply section for applying bias charges to the signal charges to be transferred from the first to the second path. In the device, bias charges supplied to the first path is transferred to the second path. Signal charges are transferred to the first path and then to the second path. The signal and the bias charges both transferred to the second path are outputted.
