Title: Foot rest device for automobile
Inventor: MORI KOICHI
IPC: B60N3/06
Filed: 1991-11-06
Abstract: PURPOSE:To dissolve fatigue of legs and more easily operate an automobile by constituting a foot rest plate to be movable. CONSTITUTION:When the vicinity of the lower end of a foot rest plate 1 is stepped in by a driver in the case of operating a control switch 11 to make a flow control valve 10 into the open condition, the foot rest plate 1 is rotationally moved in the clockwise direction, centering around a supporting point.

Title: Automatic bread maker
Inventor: NAKANO AKIHISA
IPC: A47J37/00
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To lower the temperature in a baking chamber than the outside air temperature, to easily and surely suppress the temperature of kneading and fermentation processes even if the outside air temperature is high, and to stably make tasty bread by forming an air introducing part between the baking chamber and a cooling part so as to circulate the air. SOLUTION: When materials for bread are put in a kneading vessel 2 of a baking chamber 1 to start the operation, a motor 4 is driven to rotate kneading vanes 3. Then, if it is a prescribed temperature or less in a fermentation process, the heater 5 is energized to raise the temperature, however, when it is a prescribed temperature or more, a cooling part 10 is actuated. That is to say, the temperature of the cooling part 10 brought in contact with the outer wall of the air introducing part 11 is lowered than the room temperature so as to cool the air in the air introduction part 11. Combining the low- temperature wind flowing from the wind introduction part 11 to the baking chamber 1 and a weak energization to the heater 5 can hold the bread dough to within a prescribed appropriate temperature.  This constitution can thus provide tasty bread under the same conditions despite of the high/low room temperature.

Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation in a phosphorus removal rate by a novel control method as the phosphorus removal rate degrades when the org. matter concn. in flowing-in waste water is extremely low or high in a biological treatment method for removing nitrogen and phosphorus from sewage and living waste water. SOLUTION: This control method for intermittent exposure type activated sludge method comprises first admitting the waste water into a first aeration tank in which a first ORP meter is installed, then admitting the waste water into a second aeration tank in which a second ORP meter is installed and subjecting the waste water to aerating and stirring in these two aeration tanks. The treated water is thereafter released from the final settling basin. The settled sludge is returned to the aeration tanks and is withdrawn as excess sludge, by which the nitrogen and phosphorus in the waste water are removed. The aeration time Te in the first aeration tank and the denitrification time Tf based on the detection of the ORP inflection point of the first ORP meter are measured and a DN ratio Tf/Te is determined.  The set time for nitrification, denitrification and phosphorus release in the first aeration tank is controlled from this value, by which the adequate phosphorus release quantity is assured and the degradation in the phosphorus removal rate is prevented.
