Title: Cooler for oil-filled transformer
Inventor: AKAIKE MASAHIRO
IPC: H01F27/12
Filed: 1986-06-11
Abstract: PURPOSE:To efficiently cool an oil-filled transformer by utilizing latent heat when liquefied refrigerant is evaporated by forming a spiral bead or groove on the outer surface of the inner wall of an evaporating chamber downward the liquid refrigerant outlet position of a liquid conduit. CONSTITUTION:Refrigerant sealed in a circulation system is cooled to be liquified when exhausted from a radiator 19, the liquid refrigerant is guided by a liquid conduit 21 to an evaporating chamber 18, and fed from the outlet of the chamber 18 to the uppermost part of a bead 23. Since the bead 23 is spirally inclined down from the position, the refrigerant is guided by the bead 23 to be fed to the whole periphery of an inner wall 16, and fed down from the periphery to moisten substantially whole periphery of the wall 16. The refrigerant flowing down on the outer surface of the wall 16 deprives the wall 16 of heat to be partly evaporated, and the remaining refrigerant retains in the bottom of the chamber 18, but is gradually evaporated by the heat from the interior. The evaporated refrigerant is fed from the top of the chamber 18 through a gas conduit 20 to the radiator 19, in which the refrigerant is condensed and again circulated.

Filed: 1980-09-29
Abstract: PURPOSE:In a high resolution electron microscope having a short focus objective lens, to reduce the aberrasion on and out of the axis, by forming a double stage real image through a plurality of focusing lenses arranged at the rear of the objective lens while specifying the strength of the excitation of the objective lens. CONSTITUTION:The electron beam flux 3 scattered at the point X0 on a specimen 1 positioned at the predetermined distance from the optical axis 10 is refracted by an objective lens 4 then the open angle is limited by an objective iris 5 and refracted through a focus lens 13 thereafter imaged on a material face 7 of a focus lens 15 to form a real image 14. Furthermore it is imaged on a material face 7 of a projection lens 8 through an image lens 16 to form a real image 11. A view image 12 of the real image 11 is produced through a lens 8. In such a manner the aberrasion out of the axis can be reduced by preventing the electron beam path from departing from the optical axis. Assuming the magnetromotive force of the lens 4 is J (AT) while the relatively theory correction factor of the acceleration voltage is U* (V), the strength of the excitation of the lens 4 is set in accordance to the formula. As a result the axial abberation can be reduced to produce a wide view image of good quality in low magnification range.

Title: Directivity switching system for reception antenna
Inventor: TAKEDA SHIGEKI
IPC: H04B7/08
Filed: 1979-10-17
Abstract: PURPOSE:To simplify the circuit constitution, by switching the directivity of the  reception antenna with a control given to the tuning voltage of the tuning circuit  following plural numbers of electric reception parts and then giving a switching to  the electric reception parts. CONSTITUTION:When the reception is under process by the electric reception part A1, the control tuning voltage corresponding to the reception frequency is supplied to the tuning circuit D1. Thus the reception input is taken in mainly from part A1 via the adder S. If the multipath noise mixes under reception at the part A1, the tuning voltage of the circuit D1 is switched automatically to avoid the correspondence dence to the reception frequency. And at the same time, the tuning voltage corresponding to the reception frequency is supplied automatically to either one of the tuning circuits D2-DN. Thus the directivity is switched for the reception antenna. In such constitution, the elements such as other relays or the like can be eliminated to simplify the circuit constitution.

Abstract: PURPOSE:To completely burn char and reduce unburnt matter in ash by a structure wherein refractory material is line on the water-cooled wall over the two- stage combustion zone of the pulverized coal combustion chamber for two-stage combustion in order to elevate the combustion temperature within the two-stage combustion zone. CONSTITUTION:The pulverized coal combustion chamber 1 is usually surrounded by water-cooled wall, equipped with a pulverized coal burner 2 and supplied with two-stage combustion air from an air blow-in port 3 at the location as indicated with the dash line with the arrow head. Because the combustion temperature within the zone in the neighbourhood of the pluverized coal burner 2 and at the air blow-in port 3 or within the two-stage combustion zone A lowers, when two-stage combustion is performed in said pulverized coal firing chamber 1 for decreasing NOx, the refractory material 4 is lined on the water-cooled wall over the two-stage combustion zone A. Owing to the structure as mentioned above, the combustion temperature within the two-stage combustion zone can be elevated, resulting in completely burning the char and reducing the unburnt matter in ash.
