Abstract:
PROBLEM TO BE SOLVED: To provide a circuit and a method, for temperature compensation of a temperature-dependent component of a scintillation detector for improving temperature compensation performance of the detector. SOLUTION: This scintillation detector wherein sensitivity to temperature is reduced has two circuits for the temperature compensation. The two circuits can be a circuit comprising both of a resistance element and a switching element, and a circuit comprising a thermistor connected thereto in parallel. The switching element can be a diverse element including a zener diode, a Schottky barrier diode, or an MIM (metal-insulator-metal). The circuits for the temperature compensation are included in a circuit of a photodetector such as a photomultiplier. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst carrier useful in epoxidation of olefins. SOLUTION: It has been found that the selectivity and the activity of a silver catalyst for epoxidation of olefins are a function of the distribution of the pore diameter of an alumina carrier on which the catalyst is deposited. It has been also found that a carrier having a water absorption coefficient of 35 to 55%, a surface area of at least 1.0 m 2 /g and a minimum number of pores of very large size (larger than 10 μm) is especially advantageous. A production method for such catalysts is also disclosed. COPYRIGHT: (C)2009,JPO&INPIT
