Title: Voltage detector
Inventor: IDA YOSHIAKI
IPC: G01R19/155
Filed: 1977-11-29
Abstract: PURPOSE: To perform safe power detection of high potentials with a simple and small size constitution by indirectly detecting the power from the electrostatic induction voltage between a high potential part and antenna.

IPC: E04H9/16
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To easily remove snow on a dome body by inclining a membrane of a roof and mounting a vibration device to the membrane. SOLUTION: A dome body 1 is formed of a dome portion 11 and a side wall portion 12. The dome portion 11 has a skeleton such as a truss structure 2 or the like and the skeleton is covered with a membrane 3. The membrane 3 of a roof is inclined and a vibration device is mounted to the membrane 3.

Forces of the small vibration are imparted to an area of the membrane 3, where snow 4 is attached, and the snow 4 attached is melted and a film of water is formed, and since the membrane 3 is inclined, the snow 4 slides down from the membrane 3. As a result, by imparting a small vibration to the membrane of the dome body, snow in contact with the membrane is melted so that the snow slides down from the roof so as to be easily removed.
