  • Patent number: 9709377
    Abstract: Even when a strain sensor chip and an object to be measured are bonded to each other by using a metallic bonding material such as solder, the metallic bonding material shows the creep behavior when used under high temperature environment of, for example, 100° C. or higher, and therefore, the strain detected by the strain sensor chip is gradually reduced, and the strain is apparently reduced. In the strain sensor chip mounting structure which is one embodiment of the present application, a strain sensor chip is fixed onto a surface to be measured of the object to be measured via a metallic bonding material. And, the metallic bonding material is bonded to a metallic film that is formed on a side surface of the strain sensor chip. In this manner, temporal change in a measurement error can be suppressed.

  • Patent number: 9103049
    Abstract: The crucible and the side heater are held in the respective initial positions, and the raw material is put into the crucible. These initial positions are positions where the crucible side surface is mainly heated by the side heater. When the side heater heats the crucible side surface, the raw material is melted to form melt. When a part or all of the raw material is melted, the crucible is raised from the initial position or the side heater is lowered from the initial position. At this time, the position of the crucible or the side heater is adjusted such that the amount of heat applied to the lower side curved portion of the crucible side surface is greater than that in the initial relative position between the crucible and the side heater.
