摘要:
The present invention provides sputtering targets which are useful for depositing ferroelectric films and are resistant to crack generation during sputtering. The sputtering targets comprise a disk target which is formed using a sintered material including a compound oxide of Ba and Ti, Sr and Ti, or Ba, Sr and Ti, and which has a surface which has been subjected to grinding, wherein the scratches 4 formed on the surface of the disk target due to grinding have a pattern radiating from an arbitrary point on the plane of the surface of said disk target.

This thin-film transistor includes a drain electrode film and a source electrode film, each of which includes a composite copper alloy film including a copper alloy underlayer that is formed so as to come into contact with a barrier film and a Cu layer that is formed on the copper alloy underlayer. One aspect of the copper alloy underlayer includes a concentrated layer including 2 mol % to 30 mol % of Ca, 20 mol % to 50 mol % of oxygen, and Cu and inevitable impurities as the balance. Another aspect of the copper alloy underlayer includes a concentrated layer including 2 mol % to 30 mol % of Ca, 1 mol % to 10 mol % in total of one or more selected from the group consisting of Al, Sn, and Sb, 20 mol % to 50 mol % of oxygen, and Cu and inevitable impurities as the balance.

A thrombus suction catheter which is a tube having a distal end opening formed by an angled cut surface. In the distal end opening, at least a part on the proximal end side of the cut surface is formed in a concave shape in an angled direction, and the distal end side of the cut surface is formed to be flat and flexible. With the distal end configuration, suction and crossing are significantly improved.

To provide a means capable easily releasing twist of two or more guidewires passed through a guiding catheter without pulling out the guidewires. A twist releasing apparatus has a shaft, a first tube formed at the tip of the shaft and has a first lumen through which two or more guidewires can be passed, a second tube disposed through a gap at the tip side in the axis direction relative to the first tube and has a second lumen through the two or more guidewires can be passed, and a connection portion for connecting the first tube and the second tube so that the two or more guidewires can be passed through the first lumen and the second lumen. The second tube has a slit that is formed in an axis direction and can be elastically deformed. The connection portion can be elastically deformed into a curved shape in the axis direction.
