Abstract: The present invention relates to a chip quartz oscillator. In an embodiment of a chip quartz oscillator S in accordance with the present invention, a quartz oscillator 2, which has a detection electrode 3 on a surface thereof and a non-detection electrode on the other surface thereof, is fixed on a substrate 1, and each of the electrodes is connected electrically to a terminal 4 or 4? on the substrate 1. While keeping the non-detection electrode in contact with the substrate 1, the quartz oscillator 2 is fixed on the substrate 1, by flexibly bonding the side-wall 2?? of the quartz oscillator 2 along its circumference to the surface of the substrate 1 by using the elastic bonding agent 5. Thus, the oscillation surface of the quartz oscillator 2 is supported distributively on the substrate 1 in a surface-contacting and non-adhesive manner.

Abstract: A separation material characterized by supporting, in its surface, a linear or crosslinked stimulus responsive polymer to which a substance A having specific affinity for a target substance and a low-molecular substance B having specific affinity for the substance A have been bonded. Such a separation material can increase the recovery of a target substance to be purified and do not require desalting and hapten sugar-eliminating operations and, in addition, have high productivity.

Abstract: A temperature-responsive polymer and polymer material which has ester bond(s) and/or acid amide bond(s) respectively at one or more sites in the side chain and can be arbitrarily controlled by varying the side chain is provided.
