Title: Automatic ticket checking machine
Inventor: SHIMIZU YOJI
IPC: G07B15/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To automatically clean magnetic heads and a carrier path and to prevent fault occurrence by supplying a cleaning card to the carrier path when a cleaning mode is set. SOLUTION: When a main body (a) is set in the cleaning mode, a motor M is rotated in the opposite direction of a rotation at the time of a ticket checking processing and feed rollers 6 and 6 are rotated so as to transmit the cleaning card 1 to the carrier path L with a wing W. The card 1 transmitted to the path L passes the magnetic heads H3 ', H3 , H2 ', H2 , H1 ' and H1 and cleans them and the motor M is stopped at the point of time when the card passes a reading head H1 so as to stop carrying. Then, the motor M is rotated in the direction being the same as that at the ticket examining processing. The card 1 cleans the magnetic heads again at the time of passing them and, then, stored in a holding part 5 again with the wing W.

Abstract: PURPOSE: To considerably prolong the effective work life of a chelate resin for mercury by treating the waste water with finely ground converter slag to lower the mercury concentration in the waste water then adsorptively removing mercury by  said resin.  
     CONSTITUTION: The mercury-contg. waste water is admitted into a mercury absorptive tank 1 and finely ground converter slag powder is added thereto. After these are mixed for a suitable time, the waste water is led out as a waste slurry from the tank 1. Next, this slurry is put in a classifier 2 to be fractionated and the liquid content thereof is led into a pH control tank 3. The other solid content is treated as used converter slag for setting of cement and other treatment. Moreover, hydrochloric acid or water-soluble Ca salt is added to the foregoing liquid component to control the same to about 4W6pH, after which it is supplied to a chelate resin tower 4 for mercury, where mercury is adsorptively removed by the chelate resin. As a result, even the waste water containing mercury of a relatively high concentration of e.g. ≥0.5ppm may be subjected to stable removal treatment over a long period of time at a low cost.
