Title: Refrigerator
Inventor: AKUSAWA MITSUAKI
IPC: F25D17/08
Filed: 1989-03-31
Abstract: PURPOSE:To inhibit the penetration of heat from a gasket of a door and hence maintain the freshness of foodstuffs by forming a cooled air duct which ventilates a part of circulating cooled air on a vertical middle partition column and a horizontal partition column. CONSTITUTION:A cooled air duct 13 which leads from the top to the bottom is formed in a vertical middle column 2 on the side of a chamber. The duct 13 is communicated with a cooled air passage 8. The cooled air which is heat-exchanged at a vaporizer 22 is discharged from a blowoff port 19 to the cooled air passage by a blower 23. After having cooled an upper heat conduction box 6, the cooled air passes through a communication port 29, cools a lower heat conduction box 7, returns from a lower communication port 28, passes through a passage 8B, and returns again from the vaporizer 22 from a suction port 20. A cooled duct 38 is formed on a horizontal inside partition column 31 on the side of the chamber. A part of circulating cooled air discharged to a cooled air passage 36 repeats a circulation motion which the cooled air returns to the cooled air passage 36 from a left opening section 40, passing through the cooled air duct 38. Since the horizontal middle partition column 31 is cooled by the cooled air as a result, it is possible to prevent the penetration of heat from a gasket 33A mounted on the inner peripheral surface of a door 33 and a bedewing prevention heater 34 into a storage chamber 37.

Filed: 1988-04-05
Abstract: PURPOSE:To obtain a composite bonding wire, which has excellent strength and corrosion resistance and product cost of which is reduced, even in an extremely small-gage wire having the high frequency of usage and a wire diameter of approximately 30mum<phi> by using an Al alloy containing a specific quantity of one kind in Si, Mg and Mn as a core while employing Al having specific purity as a skin material. CONSTITUTION:An Al alloy including one kind at 0-2.0wt.% in Si, Mg and Mn is used as a core material and the sectional area factor of the core material is brought to 50% or more while Al having not less than 99.99wt.% purity is employed as a skin material and the thickness of the skin material is brought to 1mum or more. Si, Mg and Mn improve the strength of Al as the core material, and also do not form an intermetallic compound with Al at that time. When content is less than 0.5wt.%, the effect of addition is not displayed, and wire strength required is not acquired. When content exceeds 2.0wt.%, on the other hand, ductility is deteriorated, and an extremely small-gage wire having a wire diameter of approximately 30mum is difficult to be manufactured. When the sectional area factor of the core material is less than 50%, wire strength needed is not obtained.

Title: Distribution line thunderproof system
Inventor: SUMIYA ICHIRO
IPC: H02H9/06
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To curtail facility cost and maintenance cost of an overhead ground wire, while maintaining the stable supply of power by laying an overhead ground wire astride a utility pole where a lightning arrestor for wiring exists and poles on both side of the pole. SOLUTION: Overhead ground wires 17 are laid only for one span on both sides of a utility pole 11b, where a lightning arrestor for wiring exists. In case the facility section of the overhead ground wire 12 is subjected to thunder damage, the thunderbolt current 18 is shunted by an overhead earth wire 17, and a thunderstroke current IGW which flows into a utility pole 17b where lightning arrestors 15a-15c for distribution are arranged from this overhead ground wire 17 and a thunderstroke current IHG which flows into a distribution line 12 through a utility pole 11c cancel each other. Thus the fault caused by the excess of duty of the lightning arrestor 15 for distribution is lightened by the case, where the overhead earth wire 17 is laid an all utility poles.  Moreover, even in the case that it has received the thunderstroke current at the section without the overhead earth wire 7, the same protective effect as the case that the overhead earth wire is laid all utility poles can be obtained by the action of a horn gap 14a and the shunt effect of the overhead ground wire 17, and the outage rate is reduced.

Title: Curved optical waveguide and its production
Inventor: KONO KENJI
IPC: G02B6/12
Filed: 1992-04-06
Abstract: PURPOSE:To suppress the propagation loss of a guided wave due to unevenness of an etching surface and the radiation loss due to the curvature by decreasing the thickness-directional equivalent refractive index of at least an outside clad nearby the curved part of a core with the increase of distance from the core. CONSTITUTION:The outside clad 5 is gradually reduced in thickness and an inside clad 6 is gradually increased in thickness so as to correct the refractive index distribution. Therefore, when this curved optical waveguide is mapped on a straight optical waveguide at an equal angle, the outside and inside refractive index distributions of the curved part in the section become constant. Further, the inclinations of the thicknesses of the clads 5 and 6 are so determined that the refractive index distribution becomes flat at the time of conversion into the straight optical waveguide by the equalangle mapping. In this case, the outside nearby part of the curved part is etched a little deeper than the inside nearby part so as to equivalently correct the inclination of the refractive index distribution generated at the mesa part of the curved part.
