  • Patent number: 5583635
    Abstract: The present invention provides a method of measuring particles and an apparatus for the same, which count only particles in liquid by distinguishing between the particles and bubbles in liquid. In order to fulfill the above requirements, in the present invention, liquid to be measured flows through a flow cell at a fixed flow rate, and a laser beam is irradiated thereto. Scattering light is generated when particles and bubbles pass through a laser beam irradiation region, and the scattering light is converted into a pulse signal by a photoelectric converter. In the pulse signals, a pulse signal having a pulse width of 100 .mu.S is regarded as corresponding to light scattered by a bubble, which is omitted from the number of pulse signals. Thus, only a pulse signal corresponding to light scattered by a particle in liquid can be measured.

  • Patent number: 5362892
    Abstract: A phospholipid composition which satisfies the following requirements (i) and (ii):(i) a weight ratio of a nitrogen-containing phospholipid to the sum of a phospholipid, a glycolipid and a sterol derivative of less than 0.5; and(ii) a ratio of an area of a high-polar substance on a silica gel thin-layer chromatogram to the sum of areas of a phospholipid, a glycolipid and a sterol derivative on a silica gel thin-layer chromatogram of less than 500 area/.mu.g. A fat and oil composition containing from 0.001 to 30% by weight of the phospholipid composition is also disclosed. The present invention enables the blending of phospholipids with a frying oil, which has been considered difficult since it causes heat coloration. Thus a fat and oil composition, which is excellent in mold-release characteristics during cooking, has a good smell during heating, suffers from no coloration of oil after heating and shows a good flavor, can be obtained.

  • Patent number: 5356599
    Abstract: A continuous powder catalyst supply apparatus and a catalyst supply system that is suitable for olefin gas phase polymerization. The supply apparatus comprises a catalyst storage chamber having a catalyst inlet port and a catalyst supply port for transmitting the catalyst to the reactor. Inside the catalyst storage chamber is a catalyst supply mechanism which substantially continuously supplies the catalyst to the catalyst supply port, and a forcible discharge mechanism which forcibly discharges the catalyst, supplied from the catalyst supply mechanism, through the catalyst supply port with a pressurized gas. The apparatus can be used to supply the catalyst to the reactor with low amounts of pressurized gas. Further, the system can be configured so as to avoid contamination of stored catalyst by reactant gas.
