Title: Analysis method of impurity in insulator
Inventor: OANA YASUHISA
IPC: G01N23/225
Filed: 1979-06-11
Abstract: PURPOSE:To prevent the unstable charging phenomenon of an insulator to make stable analysis possible, by causing a metallic thin film, which is caused to adhere to the insulator well, to evaporation-deposit to the analysis surface when an ion microanalyzer is used to analyze impurity in the insulator where SiO2 is main components. CONSTITUTION:In case of analysis of impurity in the insulator where SiO2 is main components, SiO2 layer 2 is accumulated on semiconductor silicon substrate 1, and next, thin film 3 of a metal such as aluminium, titanium and chromium which is caused to adhere to SiO2 layer 2 well is caused to evaporation-deposit to layer 2. Thus, since electric charge accumulated on SiO2 layer 2 is flowed easily into the metallic thin film of a good adhesion property, the charging phenomenon is relaxed considerably. Then, metallic cvaporation-deposition layer 3 has the charging preventing effect even for glass material which has an unknown composite as an insulator and has SiO2 as main components, so that a stable density measurement of mixed impurity elements is possible.

Title: Heat island phenomenon preventer for outdoor cubicle
Inventor: SARUMURA ETSUO
IPC: H02B1/56
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To enhance cooling efficiency of an outdoor cubicle type transforming facility by attaching a filter paper to a catch basin through a funnel and actuating a floatless switch quickly when moisture adheres thereto thereby reducing adhesion of dust to transformer, capacitor, and the like. SOLUTION: An outdoor cubicle is about 2 m high and since the temperature difference is 2 deg.C between the ground surface and the height of about 1.8 m, dust enters through natural convection of air into the outdoor cubicle and adheres to a transformer, a capacitor, a circuit breaker, and the like. Consequently, cooling effect is lowered and an electrical accident may occur when the dust contains moisture. In order to prevent such a trouble, a thermostat 1 is actuated as the temperature rises and a fan is rotated forward or reversely to take is cold air from the upper part at least when the temperature rises and to push out dust upward from below. Furthermore, a filter sheet placed on a funnel is attached to the catch basin and the forward/reverse switch of an electromagnetic switch is actuated by means of the float switch 4 of an electrode rod in order to prevent intrusion of moisture.

Filed: 1987-03-27
Abstract: PURPOSE:To correctly display the residual amount of the fuel by forming a protrusion on the upper surface of an operating plate for supporting the central part on the lower surface of a cartridge tank, and displaying the residual amount of the fuel within the cartridge tank in accordance with the resistance value of a variable resistor varying with the movement of the operating plate. CONSTITUTION:An operating plate 10 is provided on its upper surface with a protrusion 11 for supporting the central part of a cartridge tank 1, one end of the operating plate 10 being mounted swingably on a fulcrum pawl 3a on a fixed oil level apparatus 3 and the other end thereof being provided with a handle 13 which is supported by a spring 14. The cartridge tank 1 does not produce a rotational moment because the tank 1 is supported at its lower surface central part by the protrusion 11, and hence the friction with a tank guide can be reduced. When the operating plate 10 is pulled up by a force exerted by the spring 14 in accordance with the fuel consumption of the cartridge tank 1, a lever 16 is moved and the value of a variable resistor 15 varies. Thus, a current flowing through an ammeter 17 varies to display the resistance value of the variable resistor 15, i.e., the fuel residual amount within the cartridge 1.
