摘要： A method of forming, through plasma chemical vapor deposition technique, an amorphous silicon film, one side thereof intended for ohmic contact with specifically an aluminum electrode in a semiconductor device, comprising the steps of: introducing a starting gas containing at least a silicon-containing gas into an evacuated container; and subjecting said gas to plasma chemical vapor deposition through a glow discharge at a power density of 0.3 W/cm.sup.2 or greater. The particular a-Si region thus obtained provides a good ohmic contact with an aluminum electrode which is low in price and in melting point but high in reliability. In case an active a-Si region is desired, it is only necessary to lower the power density to a level below 0.3 W/cm.sup.2.

摘要： An ultrasonic probe includes a piezoelectric material layer having a pair of electrodes provided on both main surfaces thereof for applying voltage thereto, and a backing material provided on one electrode. The backing material has an acoustic impedance lower than that of the piezoelectric material layer. Interposed between the backing material and one electrode is an acoustic reflecting material layer which has a thick first portion and a thin second portion. The second portion may have a substantially zero thickness to allow the backing material to be in partial contact with one electrode. Thereby, the ultrasonic probe can transmit and receive ultrasonic waves at its resonance frequencies. Also provided is an ultrasonic diagnostic apparatus which displays an image resultant from combining images having the frequencies obtained by driving the ultrasonic probe.

摘要： A catheter includes a sheath main body portion, a first lumen, a sheath distal end portion, and a second lumen. The sheath main body portion is inserted into an organism. The first lumen is a passage provided in the sheath main body portion and through which a guide wire for guiding the sheath main body portion in an organism can be passed. The sheath distal end portion is provided on a lateral side of a distal end portion of the sheath main body portion. The second lumen is a passage different from the first lumen, provided in the sheath distal end portion, and through which a guide wire can be passed. The catheter can have both ease of exchange of catheter, which is the merit of an RX type catheter, and distal end pushing force transmission performance (pushability), which is the merit of an OTW type catheter.
