Title: Portable water supplying device
Inventor: WATANABE KAZUSHIGE
IPC: C02F1/50
Filed: 1995-06-19
Abstract: PURPOSE: To provide a device capable of preventing the contamination of water by transpiration of effective chlorine and the infiltration of bacteria, etc., and exactly sterilizing potable water and supply pipelines by stable formation of the effective chlorine. CONSTITUTION: The electrolysis of the potable water F during the course of supply is subjected to its electrolysis in an electrolytic cell 5 of a hermetic type and, therefore, the effective chlorine generated by the electrolysis is completely incorporated into the potable water F. In addition, the infiltration of the bacteria, etc., from outside is prevented and the contamination of the water is surely averted. Since the electrolysis of the potable water F is executed in the process that the water passes the electrolytic cell 5 of the hermetic type, always the specified chlorine concn. is assured regardless of water feed intervals and the sterilization of the potable water F and the supply pipelines is stably executed with high accuracy.  Further, the potable water F flowing into the electrolytic cell 5 is subjected to air venting on its upstream side and, therefore, the occurrence of the variation in the feed rate of the potable water F by the intrusion of the air is prevented.

Title: Reception system for multifrequency signal
Inventor: MURAMATSU RIYUUJIROU
IPC: H04Q1/457
Filed: 1979-11-26
Abstract: PURPOSE:To increase the protective characteristics for momentary interruption, by performing signal detection with the fixed threshold value of comparatively high level, then switching the threshold value after detection to the value of low level performing the signal detection afterward. CONSTITUTION:A multifrequency signal input is converted into a linear PCM code and fed to an adder 16 after being frequency spectral. In this case, since the preceding input signal is absent, the first fixed threshold value of a selection circuit 15 is selected and the 1st threshold value is fed to the adder 16 from a threshold value generating circuit 13. Then, the output level of a discrete Fourier transformation operating circuit 12 is compared with the 1st fixed threshold value for signal detection. Next, from the result of detection, the selector circuit 15 is switched to select the second fixed threshold value lower in the level than the 1st threshold value. After that, the output of the circuit 12 is compared with the 2nd threshold value to detect the signal. If momentary interruption is caused, when the time width of the monentary interruption is within a permissible range, the output level of the circuit 12 is not lowered than the 2nd threshold value.

Title: Ring shape optical communication system
Inventor: OOSHIMA SHIGERU
IPC: H04B10/29
Filed: 1980-10-31
Abstract: PURPOSE:To reduce noise and transmission loss, by flowing a signal to both directions of a ring by a transmission station, and blocking the signal transmission to one reception station out of two reception stations having maximum transmission loss. CONSTITUTION:When a transmission 22 makes transmission, an optical signal is transmitted to both left and right directions as arrows 27, 28. Stations 23, 26 pick up a part of optical signals and the rest transmits to a ring shape optical fiber cable as it is. At stations 24, 25 which are final with left and right direction, all the optical signals are picked up from the ring shape optical fiber cable for reception. Thus, when the final station receives all the lights, no light remains in the ring shape optical cable, allowing to reduce malfunction. Since the optical signal transmits only at a half circle at all time, the loss is a half, the transmission line can be  extend ed or the station number can be further incrrased for system constituion.
