摘要:
A novel 5-fluorouracil derivative of the formula: ##STR1## wherein R.sup.1 is a fluorine-containing C.sub.1 -C.sub.10 organic group which optionally contains sulfur, oxygen and/or nitrogen. The novel 5-fluorouracil derivative is useful as a carcinostatic substance, which has a high carcinostatic activity but which is less toxicity against digestive tract and causes less autonomic imbalance than other known 5-fluorouracil derivatives.

Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management server 10 instructs the generation of configuration setting files 23, 30 to host computers 20, 30 selected so as to form copy pairs. If the configuration setting files are generated by host agents 21, 31, the management server 10 instructs copy start to a host computer 20 having a primary volume. The host agent 21 generates a prescribed command via a copy pair control module 22 and causes a storage subsystem 40 to execute copying between the volumes. When copying is completed, the management server 10 acquires the newest storage configuration information from the storage subsystem 40 and updates configuration information DB12.
摘要:
A D/A conversion apparatus includes a DSP which receives and converts input digital data with different conversion factors, to generate a plurality of digital data having different levels, selects one of the plurality of the generated digital data, depending upon the signal quality of the input digital data, while attenuating the other digital data to be lower than a predetermined noise level. A plurality of D/A converting devices convert the respective generated digital data into corresponding analog signals. A re-converting device converts the level of each of the analog signals into an original level, based on a corresponding one of the conversion factors with which the input digital data is converted by the DSP. An adding device adds the re-converted analog signals. An attenuating device attenuates, in an input stage of the adding device, medium-to-high frequency components of at least one of the analog signals generated by at least one of the D/A converting devices that receives the attenuated digital data, and corresponding to digital data obtained by converting the input digital data with a smaller conversion factor than that of the digital data selected and generated by the DSP.

An ultrasonic diagnostic apparatus operates such that the ultrasonic beam transmission and reception is made in the same scanning direction twice at intervals shorter than the frame rate. A subtraction operation is performed between line data obtained by the successive transmissions and receptions. A subtraction image is formed by subtraction image data obtained by scanning in a plurality of scanning directions.

An image showing the spatial distribution of the hardness of a tissue of an object to be examined from which the influence of the pressure amount is eliminated is displayed.From ultrasonic tomography data measured by pressing the tissue, a physical quantity relating to the distortion of the tissue at measurement points of the tissue is determined.An elasticity image of the tissue is created according to the physical quantity.The physical quantities at the measurement points are indexed by using the physical quantity in a reference region determined in the elasticity image as a reference, and an indexed elasticity image showing the distribution of the index value is created.
摘要:
A floating type analog-to-digital converter which is capable of converting an analog signal into a digital signal in a wide dynamic range, while exhibiting stable frequency characteristics due to the presence of symmetric pre-echo and post-echo in the impulse response waveform. An analog signal level adjusting device adjusts the level of an analog signal with different first gains, so as to generate a plurality of analog signals of different levels for analog-to-digital conversion. A plurality of analog-to-digital converters convert respective ones of the plurality of analog signals generated from the analog signal level adjusting device, into respective digital signals, and output the digital signals. A digital signal level adjusting device adjusts the levels of the digital signals with different second gains corresponding to respective inverses of the first gains, and generates the adjusted digital signals, which are then delayed and generated by a delay device. A switching device selects one of the digital signals generated from the delay device, based on the level of one digital signal selected from the digital signals generated from the plurality of analog-to-digital converters, and generates the selected one digital signal.
