Filed: 1991-08-28
Abstract: PURPOSE:To regenerate active carbon in the course of producing alkaline ionized water by passing the acidic water formed on the anode of an electrolyzer through an active carbon cartridge to desorb an org. matter having an acidic group and cleaning the active carbon. CONSTITUTION:When purified water is supplied, city water is introduced from a water feed port 2, purified by an active carbon cartridge 5 and then sent to an electrolyzer 6. A switch 11 is pushed, hence alkaline ionized water is supplied, and simultaneously acidic water is discharged from a water discharge port 3. When the active carbon is regenerated, the acidic water obtained from the anode side of the electrolyzer 6 is passed through the cartridge 5 and the active carbon is cleaned. Meanwhile, when plural cartridges 5 are provided, water is firstly purified by one cartridge and then sent to the electrolyzer 6. The switch 11 is pushed, hence alkaline ionized water is supplied, and simultaneously acidic water is sent to the other cartridges to clean the active carbon.

Title: Judging device for deterioration of catalyst for engine
Inventor: HITOMI MITSUO
IPC: F02D41/14
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent the aggravation of exhaust gas during judging deterioration by accurately detecting the minute deterioration of a catalyst with controlled cost-up, and carrying out the feedback control of an air-fuel ratio at the same time as the deterioration judgement of the catalyst. SOLUTION: In the case where dither is added into the feed back control of an air-fuel ratio, in the catalyst of normal level, when a sensor output on the downstream of the catalyst is 1.0Hz in the fluctuation frequency of air-fuel ratio fluctuation on the upstream of the catalyst, the sensor output begins to vary toward a lean side, and in the case where the fluctuation frequency is less than 0.5Hz and varys largely, in the catalyst of deterioration level, a sensor output on the downstream of the catalyst begins to vary toward a lean side under such conditions as the variation frequency of 3.0Hz, and fluctuation width of &p1.0(A/F), and in the case where the sensor output is less than 2.0Hz, the sensor output on downstream side largely varys toward the lean side.  Thus even the slight deterioration of the catalyst can be accurately judged by paying attention to the above a large fluctuation to very the setting of the fluctuation frequency of the air-fuel ratio fluctuation on the upstream of the catalyst (in the above example, setting up as 2.0Hz).

Title: Josephson drive circuit
Inventor: NAGASAWA SHUICHI
IPC: H03K17/92
Filed: 1984-10-17
Abstract: PURPOSE:To attain high speed reset operation without requiring a special reset means to a line to be driven by connecting the line to be driven and a load resistor to an output terminal of a Josephson logical circuit in series and connecting a bias current descending circuit between the logical circuit and a bias current source. CONSTITUTION:In applying an input signal 108 while a bias current is fed between terminals 106 and 107, an RCJL OR circuit 201 transmits an output current to a line 103. In this case, the resistor 104 is selected so as not to reset Josephson elements 203-205 to zero voltage state. In applying an input signal current to the bias current descending circuit means 202, the bias current descends rapidly in the circuit 202 by the action of the Josephson elements 210-212. Since the output current cannot follow this trailing, the current flowing to the elements 203-205 descends rapidly than the bias current and a negative current flows after the current reaches zero. In this case, a punch-through is caused in the elements 203-205 and keep a high impedance being 5-6 times the load resistor 104. The trailing time of the output current is evaluated by a time constant L/R of the circuit. Thus, the time is brought into 1/5-1/6 of the time without the punch-through.
