IPC: G01N11/00
Filed: 1982-11-30
Abstract: PURPOSE:To obtain desired temperature decreasing characteristics, when a material under test is cooled by a cooling means having a refrigerent circulating path in order to decrease the temperature, by using a controllable heating means at the same time, and controlling the heating of the heating means. CONSTITUTION:A cooling means having a refrigerent circulating path and a heating means that can be controlled are provided in a temperature control device. At first, a sample is cooled from a specified temperature by using only the cooling means including the refrigerent. The temperature decreasing curve at this time is obtained and stored in a computer. Computation is performed in order to obtain the control characteristics, which are required to change said temperature decreasing characteristics into the desired low speed temperature decreasing characteristics. The cooling is performed again from the same initially set temperature under the same conditions. The heating control of the heating means is performed based on the data, which is obtained by computation in advance. Thus, the equal speed temperature decreasing characteristics as shown in the Figure as an ideal temperature characteristic (b) is obtained.

Title: Ultrasonograph
Inventor: TAKAMATSU KATSUYUKI
IPC: A61B8/00
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To improve operability by retrieving the same item as the inputted item name, displaying a menu image plane containing the item, and moving a cursor on the image plane. SOLUTION: When the initial image plane of a menu is displayed on a monitor 4, an operator operates a console 6 to type-input the name of the item to be set or changed, i.e., target item. A computer system 1 retrieves the inputted item name and displays a menu image plane containing the item on the monitor 4. If no coincident item is found, an input error is set, and a re-process is urged. The operator moves a cursor according to the display of the menu image plane. When the alphabet sequence display of the item name is effective, the item alignment process can be made before the retrieval item is inputted. Operability can be thus improved.
