  • Scanning probe microscope
    Patent number: 7954165
    Abstract: A scanning probe microscope is provided, which can be stably used for a long time even if excitation efficiency varies during scan. A cantilever (5) is excited, and the cantilever (5) and a sample are subjected to relative scanning. A second-harmonic component detection circuit (31) detects second-harmonic component amplitude of oscillation of the cantilever (5) as integral-multiple component amplitude. The second-harmonic component amplitude is amplitude of a second-harmonic component having a frequency twice as high as excitation frequency. An excitation intensity adjustment circuit (33) controls excitation intensity based on the detected second-harmonic component amplitude such that the second-harmonic component amplitude is kept constant.

  • Hot melt composition and use thereof
    Patent number: 6303684
    Abstract: A hot melt composition including 100 parts by weight of a styrene thermoplastic elastomer having an intrinsic viscosity [&eegr;] of not less than 1 dl/g and 200 to 3000 parts by weight of a liquid softener selected from process oil, liquid rubber and a modified substance thereof, wherein: (a) the composition has a softening point measured by ring and ball softening pint method of from 120 to 230° C.; (b) the composition generates no crack when not less than 75% of a compressive strain is applied under an atmosphere of a temperature of −30 to 40° C.; and (c) the composition does not flow when it is allowed to stand in a load-free state under an atmosphere of a temperature of 100° C. for 24 hours.
