Title: Ultrasonic diagnostic method
Inventor: ARITA KISHIO
IPC: G01S15/89
Filed: 1982-07-02
Abstract: PURPOSE:To enable the imaging of a defect by low frequency ultrasonic waves, by a method wherein ultrasonic propagation times in plural directions passing the center point of a measuring cross area, a defect part present on the measuring cross area and the distance of the defect part and the outer periphery of the cross area are respectively measured and detection is carried out on the basis of these measuring results and a reference propagation time. CONSTITUTION:Ultrasonic propagation times are measured in plural directions (P0-P7 P0'-P7') passing the center point Q of a measuring cross area 10 and a defect part H is subsequently measured from ultrasonic propagation times in plural parts of the measuring cross area 10 while the distance of the defect part H and the outer periphery of the measuring cross area 10 is further measured. By this method, a defect part is detected from these measuring results and a reference propagation time of ultrasonic waves passing the center point of the cross area (not shown by the drawing) in the normal part of an object to be measured. As mentioned above, because plural detection procedures are taken, the position and the shape of a defect part can be detected and imaged by relatively low frequency ultrasonic waves.

IPC: H05G2/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To suppress generation of key hole by forming a gas adsorption layer on the surface of a target. SOLUTION: A target 6 for generating a plasma is cooled by refrigerant 9 through a cooling conduction plate 7, and the gas for plasma generation 2 is adsorbed to the surface. As a result, a solid or a liquid gas adsorption layer 5 is formed on the surface of the target 6. In the case the gas adsorption layer 5 is of solidified type, its irradiation with a laser beam 10 causes generation of a gas plasma 4, and a key hole is produced at the surface of the gas absorption layer 5. Because the target 6 is however cooled, the gas 2 is adsorbed in the key hole, which is filled over time. Alike, in the case the gas absorption layer 5 is of liquefied type, key hole is produced at first, which will be immediately filled with the liquid surrounding. Thats is, the surface of the target 6 is maintained flat at all times.

Title: Method and controller for variably controlling pacing rate of heart pacemaker
Inventor: ROBAATO AREN ADOKINZU
IPC: A61N1/365
Filed: 1987-05-13
Abstract: A controller for variably controlling the pacing rate of a cardiac pacer responsive to temperature which includes a logic and control unit, a parameter communication unit, an analog to digital converter and a temperature sensor. The temperature sensor in the right ventricle or atrium communicates a value related to blood temperature through the analog to digital converter to the logic and control unit. The logic and control unit operates under control of the rate algorithm to calculate a pacing rate value related to variations in the blood temperature. The pacing rate value is calculated as the sum of a reference rate, a natural rate response term, and a dynamic race response term which contributes rate only in response to physical activity. A step rate response is also added to the calculated pacing rate when predetermined criteria related to the blood temperature and calculated pacing rate indicate the onset of physical activity. Under the control of the rate algorithm, the controller also maintains the level and rate of change of the calculated pacing rate within predetermined limits, and prevents the pacing rate from remaining at the maximum rate limit after physical activity has ceased.
