Title: Production of forged product made of al alloy
Inventor: TOKOSHIMA TERUHIKO
IPC: B21J1/06
Filed: 1988-08-26
Abstract: PURPOSE:To produce a forged product made of Al alloy with superior productive efficiency by subjecting a forging stock made of Al alloy formed into the prescribed shape to forging, to solution heat treatment consisting of holding under the prescribed temp. conditions for a specific time and water cooling, and then to aging treatment. CONSTITUTION:A forging stock made of Al alloy cast into the prescribed shape is pressed at about 450 deg.C by means of forging equipment to undergo plastic deformation, by which a forged part is prepared. This forged part is held in a heating atmosphere of about 500 deg.C for 2-5hr and water-cooled to undergo solution heat treatment. The acicular compound of eutectic Si crystallized out in the metallic structure of the above part is decomposed at the time of forging and stores the strain energy produced by plastic deformation. Accordingly, the spheroidizing of the above acicular compound can be accelerated by means of solution heat treatment in a relatively short time. Then, aging treatment is applied to the above forged part, by which the forged product made of Al alloy improved in mechanical properties, such as strength and toughness, can be obtained while reducing production cycle time and increasing production efficiency.

Title: Indoor temperature adjusting method and indoor temperature adjusting device
Inventor: SATO TATSUSHI
IPC: F25B27/00
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To perform an efficient indoor temperature adjustment under utilization of an existing facility in a building. SOLUTION: Rain water dropped on a roof passes through a discharged water pipe passage comprised of a roof surface 3, a trough 4, a vertical trough 5 and a pipe passage 6 or the like and is stored in an under-ground storing tank 7. The under-ground tank 7 keeps its inner temperature through-out year and the water stored in the tank and air may also keep a specified temperature in a similar manner. As a discharging fan 8 is rotated, air in the under-ground storing tank 7 can be discharged out a building through the pipe passage 6 and the vertical trough 5. For example, in summer season, air in the under- ground storing tank is kept at a lower temperature as compared with surrounding air temperature.  Thus, in the case that the air of this low temperature passes through the vertical trough 5 passing in the building, air of low temperature is supplied to a heat pump of an indoor air conditioner 21 and then a heat exchanging operation is performed efficiently. Therefore, it is possible to reduce a consumption power of the indoor air conditioner 21.

Filed: 1988-08-29
Abstract: PURPOSE:To reduce a required number of diodes and to reduce the cost of components by dividing switch contacts into groups of make and break contacts and providing a detouring preventing diode only on the group of the break contacts. CONSTITUTION:Switches S1-S4 being in a 1st block and switches S11-S14 being in a 2nd block are all formed to be make contacts. Since plural switches are not simultaneously turned on, no detouring takes place even in the absence of any diode. Moreover, switches S21-S24 are selected to be switches or selector switches with brakes contacts, then diodes D1-D4 are provided because the switches or the like are normally turned on and it causes the detouring. Thus, the number of diodes in use is very less, the component cost is reduced and the mounting space is saved simultaneously.
