Title: Vacuum-type circuit breaker
Inventor: OTOBE KIYOBUMI
IPC: H01H33/66
Filed: 1990-01-25
Abstract: PURPOSE:To shut a large electric current without any apparatus for protection from surge current by specifying pole opening speed 200-400mus before and after poles are opened. CONSTITUTION:When a trip signal is input, a motor starts working to rotate a cum 9 clockwise, and a roller 10a moves from the position where a tip stopping part is locked to the position where it is locked at a first step part. As soon as the roller 10a comes is contact with the first step part, a wipe is removed by a wipe spring 12 and during the roller 10a moves from the base part to the end part, the stroke of the roller 10a increases slowly and pole opening speed is made high. The speed of a contact of a vacuum valve 4 is set to 0.03m/s or less for 200-400mus after pole opening and to 1m/s or more after that. Consequently, high frequency electric current due to arc regeneration becomes small and large current can be shut off without installing an apparatus for protection from surge current.

Title: Water purifier with pressurizer
Inventor: UNNO TAKASHI
IPC: C02F1/28
Filed: 1979-02-13
Abstract: PURPOSE: To always maintain an optimal speed at a water purifier regardless of the pressure of  driving water in particular, by providing an open-structured water container which is an outer  case containing a filter housing in which a filter element is housed and by integrally forming a  water hose connection port on a handle provided on the water container.   
     CONSTITUTION: A water cock 23 is opened to normally obtain untreated water from a raw water  outlet port 22. A switching lever 21 is operated to switch a passage to a treated water feed port  20 and supply treated water to a water container 4 through a water hose 18. When an appropriate quantity of the treated water 19 is stored in the water container 4, a float switch is actuated  to rotate an impeller 12 and suck the treated water 19 from a suction port 3. The sucked water  is pressurized and introduced into a filter 17 so that the treated water is removed of turbidity  and bleaching  powder smell and then recovered at 16. Since the water container 4 is transparent,  the water level therein can be confirmed. Therefore, the water cock can be closed when a necessary quantity of the treated water 19 is stored. The water is thereafter pressurized and treated.  If a water level to open the float switch is set lower than the bottom of a filter container 15 but  higher than the top of a wheel 12, the handling of the container 15 is facilitated and a pressurizer  is prevented from racing.
