Title: Preparation of high purity water
Inventor: OINUMA MASAYOSHI
IPC: C02F9/00
Filed: 1993-02-10
Abstract: PURPOSE:To reduce TOC(total organic carbon) in superhigh purity water by allowing untreated water containing urea to pass through a purity water prepara tion device after treating the untreated water biologically. CONSTITUTION:An organic component such as urea is decomposed by a biological treatment device 1 using an organic component in recovered water. This biotreated water is separated by membrane in a UF or MF membrane separation device 2. Next, the pretreated water treated throughout a pretreatment device A is separation-treated using a two-stage RO membrane using a first and a second RO membrane separation device 3, 4 in a primary purity water preparation device B, and is subjected to ion exchange using an ion exchange device 5. Next, TOC contained in the treated water is ionized or decomposed using a low voltage ultraviolet oxidation device 7 in a secondary purity water preparation device C, and the ionized organic substances are removed using an ion exchange device 8. Further, the ionized organic substences are membrane- separated using a UF membrane separation device 9. Thus, it is possible to reduce the TOC level in the superhigh purity water.

A belt wheel 7 is fitted rotatably on the shaft part 5a and the shaft part of the minute hand 6 is pressed and coupled in the cylinder part 7a of the belt wheel 7. Minute gradations of 5min and minute numbers are displayed on the outer periphery of the minute dial 9. A belt 12 is stretched on the top of the minute shaft 4 between a belt wheel 11 and belt wheel 7 and rotation is transmitted from a minute hand shaft 4 to the minute hand 6. Therefore, when a timepiece machine body 2 rotates the hour hand 2, the minute dial 9 also rotates along the outer periphery of the hour dial 1. Further, the minute hand 6 is applied with the driving force from the machine body 2 from the minute hand shaft 4 through the belt wheels 11, 12, and 7 to make on turn in 1hr. Even when the minute hand 6 rotates, the dial 9 neither rotates nor oscillates because of the operation of a weight 10.
