Abstract: PURPOSE:To reduce the thermal distortion of a pressure sensitive part, to suppress the movement of a zero point and to detect pressure with high accuracy by detecting the variation of the temperature of a semiconductor diaphragm and switching the supply direction of impressed power on a thermoelectric cooling element. CONSTITUTION:When the temperature of a substance whose pressure should be detected, which reaches the pressure receiving surface 4a of the silicon diaphragm 4 through a pressure induction pipe 2 and a pressure transmission hole 14, rises, the value of the semiconductor pressure sensitive resistant element formed all over the surface of the diaphragm 4 is changed and a thermoelectric cooling element driving circuit is actuated. Then, the power from a DC power source is supplied to the thermoelectric cooling element 11 and an endothermic action is performed on a substrate 13b side so as to gradually lower the temperature of the diaphragm 4. When the temperature of the substance whose pressure should be detected lowers, the supply direction of the impressed power on the element 11 is switched and a heat generation action is performed on the substrate 13b side so as to gradually raise the temperature of the diaphragm 4. Thus, the silicone diaphragm 4 is held at a desired set temperature with a temperature compensating action, thereby detecting the pressure with high accuracy.

Title: Joining structure of building
Inventor: MAEDA KENICHI
IPC: E04B1/348
Filed: 1995-04-03
Abstract: PURPOSE: To make it possible to confirm easily that a building is properly joined by clamping a joined state conformation board in a joining area of bolts and allowing the joined state confirmation board to be deformed in a flattened state from curved shape in a free state after the end of joining operation. CONSTITUTION: When joining joint materials 1A and 1B with a bolt 2 and a nut 3 and gaskets 4, a joined state confirmation board 5 is clamped in a joining area of the bolt 2. This joined state confirmation board 5 is placed in curved shape in a free state before joining work comes to an end. After the end of joining work, it is so arranged that the board 5 may be changed into flattened shape by a joining force after the end of joining work. More specifically, when a proper joining force is applied, the degree of a curved surface in the free state is determined so that the joined state confirmation board 5 may be joined with the joining materials 1A and 1B. Therefore, the board 5 is not in a flattened state in a stage when the joining force has not reached a proper value but it is turned in a flattened state in the stage when it has reached the proper value, which makes it possible to confirm that the bolt is fastened with the proper fastening force.
