Title: Protective device of electric, electronic or other mechanical device
Inventor: ISHII SHIGERU
IPC: H05K5/02
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To hold the inside of a device under high pressure, and to prevent infiltration of moisture/dust by arranging a through hole in a casing of the device, and communicating a pressure atmospheric pressure source such as a compressor with this through hole through an opening/closing valve and a dryer. SOLUTION: Atmospheric pressure of a pressure atmospheric pressure source 6 is increased by 0.02 to 1.00 atmospheric pressure more than one atmospheric pressure of atmospheric pressure of a chamber to hold a flow of a small quantity of gas. Since the inside of a device is held under high pressure, air is only blown off from any place of the upper/lower/left/right sides of a device 1 to prevent infiltration of moisture/duct into the device 1 from outside. An effect capable of checking the degradation of a part in the device 1 can be fulfilled when inert gas such as nitrogen and carbon dioxide gas is used as the pressure atmospheric pressure source 6 instead of air. Dew condensation can be reduced when an inner box is arranged in a casing 2 of the device 1 through the vacuum heat insulating part.  The dew condensation can be prevented while cooling a largely heat radiating part when faced to the largely heat radiating part by adding a hose extending from a through hole 3.

Title: Snow-melting spiral rod for overhead power transmission line
Inventor: YOKOYAMA KAZUO
IPC: H02G7/16
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To obtain a snow-melting spiral rod sufficiently effective at melting snow even at low power flow. SOLUTION: The snow-melting spiral rod 13 is a spiral wire obtained by roughing the circumferential surface of a wire 5, a low-Curie wire 1 coated with aluminum coating 2 by blasting and thereafter forming a dark gray anodic oxide coating film 11, 5 μm-30 μm in thickness by anodic oxide coating. Thus, far infrared rays with a wavelength of 2.5 μm-30 μm can be radiated at an emissivity of 0.65-0.80. Since in the snow-melting spiral rod, transfer of heat by radiation is added to conventional transfer of heat just by conduction and further transfer of heat by radiation is remarkably excellent in heat transfer efficiency as compared with conduction, the spiral rod is highly efficient. The snow-melting spiral rod produces sufficient snow-melting effect even at a low power flow without increasing its amount of winding.  Thus, the snow-melting spiral rod is applicable to overheat power transmission lines requiring consideration of low power flow periods.
