Title: Three-dimensional ultrasonic scanning of tissue movement and apparatus therefor
Inventor: PESQUE PATRICK RENE
IPC: G01S15/89
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To enable to three-dimensionally observe the specific lesion of an organ by processing ultrasonic Doppler information signals and displaying received Doppler power strength based on motion of an organ or a tissue by space basis in a three-dimensional display. SOLUTION: An ultrasonic probe is moved on the whole chest above the heart. A converter 12 is activated every time when the heart is at a desired phase in a pulse cycle determined by pulses generated by the heart to be sent to a transceiver 14. Thereby, one or more series of Doppler power images of the left ventricle are obtained and are stored in an image series memory 36. The planar Doppler power image at a selected heart phase is read out from the image series memory 36 and each planar image is rotated by an observation angle and is projected on an observation plane. Each projected planar image is overlapped on a previously accumulated projection image at a converted position in the image plane, which is the function of the observation angle and the plane interval, to be a Doppler power picture element.

Abstract: PURPOSE:To prevent a tape from deforming and damaging and the tape running system of a device from damaging and wearing off, by providing a control circuit which stops the magnetic tape when the tape exceeds a predetermined tension limit. CONSTITUTION:Electric signals B, C, and D obtained from a tension detector 14 provided to a tension post 8', cylinder motor 15 which rotates a cylinder 11 at a specific speed, and capstan motor 16 which rotates a capstan 12 at a specific speed are read by reading circuits 17a, 17b, and 17c, which output tension signals E, G, and G. Those tension signals E, F, and G are compared with the limited tension signal of the tape by comparing circuits 18a, 18b, and 18c, which send out output signals H, I, and J, respectively. A signal generating circuit 19 when supplied with one of the signals H, I, and J outputs a stop command signal K for a tape running.

Title: Pwm driver
Inventor: HAYASHI YASUHIRO
IPC: G11B7/09
Filed: 1989-03-29
Abstract: PURPOSE:To stabilize the gain of a driving output regardless of potential drop of a power source by generating a coefficient which becomes larger as the voltage value of a battery becomes smaller, multiplying the coefficient to a control signal applying pulse width modulation to the result, and sending the result to the drive switch circuit of a load to be controlled. CONSTITUTION:At first, the string of the coefficients, whose value becomes larger in correspondence to the output of a power source 17 becomes smaller, is stored to a coefficient generator 24. Thus, a coefficient K to be increased in correspondence to the power source drop of the power source 17 is sent to a digital multiplier 22 and multiplied to an FE signal from a digital phase compensator 21. Thus, the FE signal is increases the gain with the reduction of the voltage in the power source and as a result, the gain of the output to an actuator 18 is stabilized. Thus, even when the gain of a drive switch circuit 16 is lowered with the reduction of the voltage in the power source, the gain of the output to the actuator 18 can be stabilized since the gain of the FE signal is simultaneously increased. Then, the open loop gain of a servo system can be kept almost constant.

Title: Hydraulic machine
Inventor: TANABE SEIICHI
IPC: F03B11/08
Filed: 1983-05-04
Abstract: PURPOSE:To prevent abrasion of seal parts by providing a water chamber for accumulating mud and sand at the outer periphery of a pressure chamber. CONSTITUTION:Water, passing through a seal 14 and including mud and sand, obtains a whirling speed substantially equal to the rotating speed of a runner when it passes through the seal parts. The axial flow speed of the water is decreased near the entrance of a mud and sand chamber 50, since the sectional area of the flow path near the same chamber 50 is large, and the components of the speed are changed into the whirling component only. The whirling speed affects greatly near the entrance of the mud and sand chamber 50 and in the same chamber 50, therefore, the mud and sand move to the outer peripheral side by the difference of centrifugal forces between the mud and sand and the water. When the rotation of the runner is stopped, the mud and sand are deposited at the outer peripheral side of the chamber 50. The mud and sand are discharged together with the water through a water discharging pipe 56 during stopping of the runner. The mud and sand are deposited in the pressure chamber at the outer diametral part, therefore, abrasion of the sealing parts at the inner diametral position is small.
