The film forming apparatus includes: a film forming chamber; a substrate holder located in the film forming chamber, for holding a substrate on which a structure is to be formed; an exhaust pump for exhausting an interior of the film forming chamber; an aerosol generating unit for generating an aerosol by blowing up a raw material powder placed in a container with a gas; a carrier pipe for introducing the generated aerosol into the film forming chamber; a nozzle for spraying the aerosol introduced via the carrier pipe toward the substrate; and a control unit for chaotically changing a relative position of the substrate held by the substrate holder and the nozzle. | 04-23-2009 |
20090115291 | VIBRATOR ARRAY, MANUFACTURING METHOD THEREOF, AND ULTRASONIC PROBE - In an ultrasonic transducer array, a plurality of vibrators arranged in an array is bonded to a base plate by bond material. The bond material bonds the bottom of the each vibrator to the base plate in a manner to surround lower part of the side face of the vibrator. A filling material is filled in between the vibrators. The filling material has a multi-layer structure of different rigidity. In a double layer structure of the filling material, it is preferable that thickness ratio of layer of filling material at the base plate side (lower side) to the other layer of the filling material is 1:1 to 1:3. Preferably, a beam is provided for connecting the side faces of the adjacent vibrators. | 05-07-2009 |
20110074244 | Ultrasonic probe - An ultrasonic probe has transmitting ultrasonic transducers and receiving ultrasonic transducers. The transmitting ultrasonic transducer is composed of a multilayer piezoelectric element, and the receiving ultrasonic transducer is composed of a single-layer piezoelectric element. The transmitting and receiving ultrasonic transducers are alternately arranged in an azimuth direction to form a piezoelectric element line. The single transmitting ultrasonic transducer and the single receiving ultrasonic transducer that adjoin to each other compose a single channel to transmit ultrasonic waves and receive echoes. The transmitting ultrasonic transducer is connected to a transmission circuit board on which a pulser is implemented, and the receiving ultrasonic transducer is connected to a reception circuit board on which an amplifier is implemented. The receiving ultrasonic transducer is directly connected to the amplifier without passing through a capacitance transmission line. | 03-31-2011 |
20110077520 | Ultrasonic diagnostic apparatus and ultrasonic diagnostic method - An ultrasonic probe has a plurality of ultrasonic transducers (UTs). Each UT transmits ultrasonic waves and receives echo waves. In a B/A coefficient acquisition mode, every time a transmission of the ultrasonic waves and reception of echo waves takes place, ultrasonic waves for heating are transmitted to heat an object of interest. An HI processor calculates a non-linear B/A coefficient based on a harmonic component of a detection signal from the UT. The HI processor acquires information of changes in the B/A coefficient while the object of interest is heated with the ultrasonic waves for heating. A DSC displays the information of the B/A coefficient together with an ultrasonic image on a monitor. | 03-31-2011 |
20120150038 | ULTRASOUND PROBE - An ultrasound probe which transmits ultrasonic waves to a subject, receives ultrasonic echoes generated by reflection of the ultrasonic waves on the subject and outputs ultrasound image signals includes a case having a grip portion set therein and functional units disposed in the case. The functional units include an ultrasonic wave-generating unit, at least one integrated circuit board and a battery. The battery disposed in the case at a position corresponding to the grip portion ensures the safety of operators from heat generated in the at least one integrated circuit board and the like. | 06-14-2012 |
20120296211 | ULTRASOUND DIAGNOSTIC APPARATUS - An ultrasound diagnostic apparatus includes a light irradiator for irradiating a lattice point set in the region to be imaged with light converging to the lattice point, so as to impart heat locally to the point; an image for distortion amount calculation-generating section for generating an ultrasound image for distortion amount calculation based on a reception signal of ultrasound generated; and a distortion amount calculating section for calculating the difference between the position of the lattice point on an ultrasound image for distortion amount calculation and the absolute coordinates of the lattice point as the distortion amount. Such apparatus allows precise sound speed values in the living body to be obtained and, accordingly, an ultrasound image of high accuracy to be taken. In consequence, a more accurate diagnosis is conducted on the region to be diagnosed in a subject. | 11-22-2012 |
