Abstract: PURPOSE:To ensure the sourness of fruit juice to be mitigated by degrading the organic acids, in particular, citric acid in the fruit juice using a novel lactic acid bacteria Leuconostoc sp.KS-0002 having organic acid assimilability. CONSTITUTION:Lactic acid bacteria in pieces of somewhat deteriorated mandarin orange sarcocarp are specifically proliferated in a relevant GYP medium comprising glucose, yeast extract and a citrate and then incubated in an appropriate agar-agar medium containing components similar to those mentioned above into a colony. This colony is then separated using a plate colony technique, thus obtaining the objective lactic acid bacteria Leuconostoc sp.KS-0002 with organic acid assimilability (FERM P-10313).

IPC: B21B27/10
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent the spouting of coolant to the outlet side of a rolling mill by providing an elastic body having lower modulus of elasticity than each roll to the non-contact part between the rolls and the elastic bodies having lower cross sectional secondary moment than the cross section of the barrel part of each roll on the shoulder parts of each roll. SOLUTION: The elastic body 10 is provided with the non-contact part between rolls. At this time, the elastic body having lower modulus of elasticity than that of the roll is used so as not to obstruct the bending effect of the bender of the working roll and the intermediate roll. As the conclete material example, various kinds of rubbers and various kinds of metals, are exemplified. Further, what the substantial cross sectional area at the shoulder part of the roll is reduced and the cross sectional secondary moment thereat is reduced, has the same effect as to reduce the bending rigidity at the shoulder parts of the roll. Therefore, even at the time of shifting the roll, the non-contact part between rolls, is not developed, but the effect of the roll bending is made use of.  At the time of grinding the roll, the shoulder part thereof can simultaneously be ground to the barrel part thereof.

IPC: G01N21/88
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a flaw detector to judge the existence of a flaw by quickly detecting the whole surface of a ball. SOLUTION: A light receiving unit 5 is formed by juxtaposing plural light receiving elements, and a laser beam 6 reflected by a steel ball 3 is made incident on the respective light receiving elements.

When the steel ball 3 rotates according to rotation of respective rotary shafts 1 and 2, this long and narrow belt-like part moves on the surface of the steel ball 3. Therefore, the light receiving unit 5 detects a great part of the surface of the steel ball 3 while the steel ball 3 rotates once.  A judging part 11 compares output levels of the respective light receiving elements with a threshold value by receiving output of the respective light receiving elements of the light receiving unit 5, and judges that there exists a flaw on the surface of the steel ball 3 when either of the respective output levels becomes less than the threshold value while the steel ball 3 rotates once.
