    摘要： A process for producing a flexible or rigid polyurethane foam is provided in which a polyol and a polyisocyante are reacted in the presence of an amine catalyst, a blowing agent, and a foam stabilizer, the amine catalyst comprising at least one amine compound represented by General Formula (1) below: ##STR1## where R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are respectively an alkyl group of 1 to 6 carbons independently; n is an integer of 0 or 1; and A is an alkyl group of 11 to 14 carbons when n is 0, or an alkylene group of 10 to 15 carbons when n is 1. The amine catalyst has low odor and low volatility, and gives high curing rate, and excellent moldability with a formulation of reduced fluorocarbon and increased water as the blowing agent.

    摘要： A spectrophotometer 10 includes built-in detector 24 and external detector 32. When a mountable/removable optical path switcher 23a is installed in a specimen chamber 23, measurement based on detection signals from built-in detector 24 is replaced by measurement based on detection signals from external detector 32. The spectrophotometer further includes a measurement data threshold-value storage unit 51 that stores threshold value T for measurement data from built-in detector 24 or external detector 32, and a light-receiving detector recognition unit 52 that recognizes which detector is able to receive the measuring light beam based on the results of a comparison between threshold value T and measurement data from built-in detector 24 or external detector 32 while the measuring light beam is being introduced into specimen chamber 23.
