IPC: F28F3/08
Filed: 1987-01-20
Abstract: PURPOSE:To secure positive sealing and to facilitate management for leakage by connecting annular spaces between large and small annular gaskets loaded around the peripheries of through holes connecting closed passages for introducing and leading out a fluid within the closed passage, with each other through small holes. CONSTITUTION:Heat transfer elements 4 form closed passages A and opened passages B alternately. The closed passage A communicate with each other via through holes formed in a plate 10. Around the peripheries of through holes 6, concentric circle shaped gasket grooves 12 and 14 exist annular gaskets 16 and 18 are loaded therein, to conduct double sealing between the external part and passages A. Annular spaces 20 between the gaskets 16 and 18 all communicate with each other through small holes 22. the spaces 20 can arrest a fluid leaking from gasket 16 and 18 to analyze and measure the concentration of the fluid. By these procedures, a positive sealing effect can be obtained and existence of the leakage of the fluid and the degree of the leakage can be easily checked.

Title: Controller box
Inventor: HARADA TSUKASA
IPC: H05K5/06
Filed: 1991-02-01
Abstract: PURPOSE:To avoid trouble due to dew formation in an electric component by forming a controller box hermetically and providing means which expands/ contracts, while keeping airtightness, according to expansion/contraction of air due to temperature variation thus suppressing variation of inner pressure. CONSTITUTION:A controller box A is formed by coupling a body 13 and a rear cover 14 where an expansion diaphragm 11 is held between and the chamber is split into two sections. One chamber 15 containing an electric component, e.g. a controlboard 5 for an operating switch 3, is sealed hermetically by means of the diaphragm 11 while the other chamber 16 is provided with a vent 17, communicated with the outer air, through the rear board 14 thereof. Volumetric expansion/contraction of air due to the air temperature variation in the control box A is absorbed through displacement of the diaphragm 11 in one chamber 15 thus suppressing variation of inner pressure. Pressure in the other chamber 16 formed through the diaphragm 11 is equalized to the external pressure through the vent 17 thus equalizing the pressure at the inside and outside of one chamber 15.

IPC: H01F30/00
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To reduce the height of a winding wire by a method wherein the winding wire has a structure that stepped spacers having different thicknesses in the inner diameter sides and the outer diameter sides are alternately inserted between coils on the inner diameter sides and the outer diameter sides and the interlayer dimension on an equipotential side is short. SOLUTION: The winding structure of a transformer is so constituted that one layer outer periphery electric wire 1 (a), which is connected with an applying terminal, is wound from the electric wire 1 (a) to a one layer inner periphery electric wire 1 (b) and the electric wire 1 (a) is connected with a two layer inside electric wire 1 (c) on the inner periphery side of the winding wire. Moreover, the electric wire 1 (c) is wound from the electric wire 1 (c) to a two layer outside electric wire 1 (d) and the electric wire 1 (d) is connected with a three layer outside electric wire 1 (e). As there is the number of turns of the windings two times more than that of turns of the winding in each layer between the electric wire 1 (a) and a (s) layer outside electric wire 1 (d), a voltage to respond to the number of turns of the windings is generated.  A potential difference is not generated between the electric wire 1 (b) and the electric wire 1 (c) and there is no need to ensure the interlayer insulation dimension. Accordingly, the thickness of one end of each spacer is assumed t1, the thickness of the other end of each spacer is assumed t2 and the stepped spacers 2 formed on the condition of t2<t1 are alternately arranged between coils so that the thickness t2 comes to the sides of the connection places of the wiring wire.
