    Abstract: A phase difference measuring apparatus for accurately measuring the phase difference (fine time difference) of two signals with the same frequency with a reduced number of bits for A/D conversion is disclosed. In addition to output signals of an upstream side pickup and a downstream side pickup of a mass flowmeter, an output signal of the upstream side pickup or the downstream side pickup is supplied to a comparator, a PLL circuit, an antialiase filter, a sample and hold circuit, and an A/D converter. These circuits quantize these signals and send the quantized signals to a band pass filter. The band pass filter extracts a predetermined signal component and outputs it to a DFT. The DFT performs complex Fourier transformation on the input signal. Thus, the phase difference between two signals with the same frequency (such as an upstream side pickup signal and a downstream side pickup signal) can be accurately detected with a reduced number of bits for each of the A/D converters.

    Abstract: 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.

    Abstract: A virtual camera for displaying characters to be imaged on a monitor can be readily set. In the present program, a virtual camera and imaging space are set in a virtual game space. A plurality of characters are arranged in the virtual game space. A controller determines whether or not the plurality of characters are positioned inside the imaging space. At least one option among the viewing angle of the virtual camera and the position of the virtual camera is modified. Therefore, when any single character among a plurality of characters is positioned outside the imaging space, the character positioned outside the imaging space is positioned inside the imaging space. The plurality of characters are displayed on the image display unit.
