Title: Chlorine injection controlling device
Inventor: KANEKO TOMONORI
IPC: B01D21/30
Filed: 1980-03-12
Abstract: PURPOSE: To prevent production of trihalomethane which is produced when chlorine contacts humine, by changing chlorine injecting location in accordance with the raw water containing humine or not containing humine.  
     CONSTITUTION: When the raw water contains humine, "containing humine" is input into control device 9 as input data 10. In accordance with the data, control device 9 completely closes change-over valve 7 and fully opens change-over valve 8, and injects chlorine before flock forming pond 3 after flocculant 6 is injected into rapidly agitating pond 2. In this way, the humine contained in the raw water first contacts the flocculant and is contained in the flock when the flock is formed. Therefore, there is no chance where the humine contacts the chlorine, and no trihalomethane is produced. When the raw water does not contain humine, change- over valve 7 is fully opened and change-over valve 8 is compltely closed.

Filed: 1992-02-18
Abstract: PURPOSE:To lessen an irregularity in the extrapolation values of hot carrier lives when the hot carrier lives in MOS transistors are extrapolated from the measured values of the hot carrier lives at the time of high drain voltages. CONSTITUTION:Three MOS transistors having the same channel dimension are arranged at the shortest distances of 320mum and hot carrier lives are measured under three kinds of drain voltages, which are different from one another. The hot carrier lives 20 and 21 at this time are plotted and the lives are extrapolated from these three points to calculate the hot carrier lives at a point 8, which correspond to the drain voltages at the time of actual use. Thereby, variation in the extrapolated hot carrier lives can be significantly reduced.
