20100041997 | ULTRASONIC IMAGING APPARATUS - An ultrasonic imaging apparatus includes a pulsar including an output line coupled to a piezoelectric transducer and a plurality of first push-pull circuits whose output units are coupled to the output line, and a power source unit which supplies a plurality of power source voltages with different levels to the first push-pull circuits. At least one of the first push-pull circuits includes first rectification elements which prevent reverse current from flowing into first complementary transistors configuring the first push-pull circuit. The pulsar includes a second push-pull circuit whose output unit is coupled to the output line, the same power source voltage as in the first push-pull circuit with the first rectification elements is applied to the second push-pull circuit, and current in the direction opposite to that in the first push-pull circuit flows in the second push-pull circuit by turning on second complementary transistors configuring the second push-pull circuit. | 02-18-2010 |

20130243662 | APPARATUS FOR TREATING MATERIAL COMPRISING PRESSURE VESSEL WITH DRUM ROTATABLE ARRANGED INSIDE - A pressure vessel and a drum rotatably arranged inside which has an inner space for material that is introduced into the pressure vessel. In various embodiments, a drive mechanism rotates the drum in relation to the pressure vessel. The drive mechanism can include a motor that can be located inside the pressure vessel in an interspace between the drum and the pressure vessel. Some embodiments include a door to close an opening of the pressure vessel and a part of the door can extend into an open end of the drum when the door is closed to keep the material in the drum and out of the interspace. In particular embodiments, a steam supply conduit extends into the drum at the closed end of the pressure vessel. In some embodiments, a helical agitation blade in the drum moves the material away from or toward the opening. | 09-19-2013 |
