Title: Muddy-water intrusion preventive device
Inventor: OHASHI KOSUKE
IPC: E03B1/00
Filed: 1994-12-28
Abstract: PURPOSE: To check the intrusion of muddy water from the water main pipe side to a water receiving tank. CONSTITUTION: A muddy-water sensor section 6 and a feed-water control valve 7 are fitted on its midway of a feed water pipe 1. The muddy-water sensor section 6 detects whether or not city water in the feed water pipe 1 is muddy water, and outputs the result of the detection to a control box 8. The feed-water control valve 7 closes the feed water pipe 1 when the result of the detection by the muddy-water sensor section 6 is muddy water, and opens the feed water pipe 1 when the result of the detection is not muddy water. The opening-closing operation of the feed water pipe 1 by such a feed-water control valve 7 is executed by the control box 8.  That is, when the result of the detection by the muddy-water sensor section 6 is muddy water, a closing signal S2 is output to the feed-water control valve 7 from the control box 8, thus closing the feed water pipe 1 by the feed-water control valve 7, thus the intrusion of muddy water from the water main pipe 4 side to a water receiving tank 5 is checked.

Title: Method for culturing lactic acid bacterium and apparatus used therefor
Inventor: TANNO KATSUTOSHI
IPC: C12R1/01
Filed: 1988-12-27
Abstract: PURPOSE:To enable culture of lactic acid bacterial in a state of a high concentration of lactic acid bacterial count by regulating lactose concentration in a culture medium to 1-1.5wt.%, separating and removing inhibitory substances for the lactic acid bacteria produced in the culture medium using a filtration membrane. CONSTITUTION:A new culture medium regulated to 1-1.5wt.% lactose concentration is charged into a culture vessel 1 and lactic acid bacteria, such as Lactobacillus bifidus, are inoculated and cultured therein while being stirred. Since lactic acid is produced in the culture medium and inhibition to the lactic acid bacteria is developed, the culture medium is passed through a pump 2 and a filtration membrane 3, such as vinylidene dilfuoride, to separate and discharge the culture medium containing the lactic acid from the lactic acid bacteria through a pump 4 from a discharge port 10. On the other hand, the culture medium containing the lactic acid bacteria is returned to the culture vessel 1. In the process, a fresh culture medium in an amount corresponding to that of the discharged medium is supplied through a pump 6. Furthermore, the culture vessel 1 is kept at a prescribed temperature with a thermometer. Thereby, the cultured bacterial count per unit volume can be increased to reduce production and equipment cost. Bacterial contamination due to heating at high temperatures can be prevented.
