摘要:
This invention provides a photovoltaic module for preventing insulation failure between an outer frame and connection leads. The photovoltaic module comprises: a photovoltaic submodule including a plurality of solar cells interposed between two light-transmitting substrates through the intermediary of an encapsulant and the connection leads extending from an edge between light-transmitting substrates and outputting generated electric currents; a terminal box attached near an edge of the photovoltaic submodule and housing connected parts between the connection leads and cables for outputting the electric currents to the outside; and an outer frame fitting over peripheral edges of the photovoltaic submodule. A side, of the light-receiving side light-transmitting substrate, from which the connection leads are pulled out, is made large so as to extend outward further than the other light-transmitting substrate. The connection leads are led out from the edge between the two light-transmitting substrates to be guided into the terminal box.

A powder coating material for providing a crepe-like coating having a uniformly and densely distributed superior anesthetic appearance and having a high corrosion resistance, is capable of forming color distinct ridges and valleys in the wrinkle profile of the coating layer. The powder coating material consists of a co-milled powdery product, of which the particle sizes are not higher than 105 .mu.m, and which is composed of (A) 95-99.5 parts by weight of a first resin component comprising a thermosetting resin which is solid at room temperature and (B) 5-0.5 parts by weight of a second resin component comprising a thermosetting resin which is solid at room temperature and contains 3-8% by weight of a cellulose ester. The powder coating material is prepared by co-milling pelletized resin products of the components (A) and (B).

The invention permits a plurality of strips of resin adhesive film having a desired width and unwound from a single feeding reel to be simultaneously pasted on a solar cell. For this purpose, the invention comprises the steps of: unwinding a resin adhesive film sheet from a reel on which the resin adhesive film sheet is wound; splitting the unwound resin adhesive film into two or more film strips in correspondence to lengths of wiring material to bond; pasting the strips of resin adhesive film on an electrode of the solar cell; and placing the individual lengths of wiring material on the electrode of the solar cell having the plural strips of resin adhesive film pasted thereon and thermally setting the resin adhesive film by heating so as to fix together the electrode of the solar cell and the wiring material.

The present invention provides a photovoltaic module which prevents enlargement of the dimensions of a photovoltaic submodule by reducing ineffective parts which do not contribute to power generation. The photovoltaic module comprises a photovoltaic submodule including a plurality of solar cells interposed between two light-transmitting substrates through the intermediary of an encapsulant, and a connecting lead extending from an edge between the two light-transmitting substrates for outputting generated electric current, a terminal box 30 attached near to the edge of the photovoltaic submodule housing a connecting part between the connecting lead and a cable for outputting generated electric current to the outside, and an outer frame set around the outer circumference of the photovoltaic submodule. An opening 28 through which the connecting lead and the terminal box are inserted is provided to the outer frame at a position which receives at least the terminal box.

An object is to provide a solar cell module capable of reducing warping of each solar cell due to a linear expansion coefficient difference between the solar cell and a wiring line member to prevent damages effectively without raising any cost increase. A solar cell module comprises a plurality of solar cells and is constituted by electrically connecting adjacent solar cells to one another by wiring line members, a base material of the wiring line member has a plastic strain of 2% or less in a drawing direction, and the solar cell is constituted of a crystalline wafer having a thickness of 200 microns or less.
摘要:
In a magnetron, two rods are supported by a stem in cantilever fashion and a filament (cathode) is connected between two end hats attached to two free ends of the rods. Therefore, these two rods are apt to be vibrated by an external force (e.g. an air screwdriver) during assembly or in transit. To suppress relative displacement of the two rods of magnetron due to external force, the natural frequency of the first vibration system composed of a first rod and a first end hat is determined substantially equal to that of the second vibration system composed of a second rod and a second end hat.
