IPC: F24D3/18
Filed: 1984-05-11
Abstract: PURPOSE:To enable multipurpose use of hot water, by a method wherein hot water, preheated with the aid of a heat pump, is further heated by a hot water heater to produce high temperature hot water. CONSTITUTION:A device is formed with a hot water system A for supplying hot water, running from a feed water part 7 to an hot water outlet 8 through a condenser 8, and a hot water system B for radiation in which hot water is circulated between a proper radiator, for example, a radiator 9 for heating and a bath burning heat exchanger 9'. Hot water heaters 10 and 10' are mounted to the systems 10 and 10' down the flow from the condenser 3. For example, a combustion type hot water heater 10, such as gas hot water boiler, is used as the hot water heaters 10 and 10'. When high temperature hot water is needed, with the hot water heaters 10 and 10' actuated, the high temperature hot water can be easily produced. As noted above, when high temperature hot water is demanded, the hot water heaters 10 and 10' are actuated. Further, since the temperature of the condenser 3 of a pump 1 is decreased over temperature prevailing during demand of high temperature hot water, the efficiency of the heat pump 1 can be improved.

Title: Electrostatic charger
Inventor: IWASAKI YUKIKO
IPC: B01D53/86
Filed: 1994-05-06
Abstract: PURPOSE:To remove ozone generated in a very small gap between a discharger and a body to be electrostatically charged by installing an exhaust means and an ozone decomposing means, etc., on the part not related to the discharge of an electrostatic charging electrode. CONSTITUTION:An opening 8 pierced through a base plate 4 and a semiconductive thin film layer 5 in a thickness direction of the electrostatic charging electrode 6 is formed on the part of the electrode 6 not related to the discharge on the downstream side of the point of a smallest gap (b) to provide an air discharge port in a discharge space. Thus, the air is prevented from staying in the discharge space. A honeycomb-shaped active carbon filter 9 is mounted on the opening 8 in the electrostatic charger as an air permeable ozone decomposing agent. Thus, the air passing through the opening 8 is discharged in contact with the active carbon filter 9, then, the ozone is not discharged as it is but decomposed, so that the adverse effect of the ozone is not exerted on the other parts in the device in contact with the air discharge through the opening 8.

Title: Spiral staircase
Inventor: FUJIMURA TOSHIMASA
IPC: E04F11/02
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a spiral staircase which allows easy ascending and descending and which is excellent in design. SOLUTION: In a spiral staircase where a plurality of treads 2 are spirally arranged at different height, each treated has its ascending side edge 3 formed into an outwardly projecting shape and its descending side edge 4 into an inwardly recessed shape. Thus when a climber ascends or descends, his/her outer leg is less likely to be caught by the descending side edges since the descending side edges are recessed inward. Since the ascending side edges project outward, sufficient areas to place the treads can be secured. The shape of the treads is so excellent in design that the entire stair draws attention.

Filed: 1991-04-01
Abstract: PURPOSE:To efficiently discover a wiring route between unconnected elements by displaying the direction of the opposite connection party of the unconnected element at the internal part of the endpoint or at the peripheral part of the end point of the unconnected element. CONSTITUTION:The unconnected wire endpoints 3-8 which are not wiring objects are displayed by an arrow, etc., pointing the direction of the connection party element in the neighborhood of the unconnected wire endpoints 3-8 in a conversational wiring editor which displays output data adding the unconnected element from an automatic wiring device in a display device 1 so as to process it. Thus, the complication of a display screen 2 in the display device 1 is dissolved so that a wiring possible area is easily grasped. Furthermore, a pulling-out direction which is profitable to the wiring is clearly expressed in the respective unconnected endpoints 3-8 so that the wiring area which is succeedingly used by another connection wire is predicted as to the area in the neighborhood of the unconnected wire endpoint which is a wiring object at present. Therefore, connection wire can be previously installed by avoiding the wiring area so that the handling time at the time of installing a wiring pattern is reduced.
