摘要:
For efficiently forming a semiconductor element with excellent adhesion and environment resistance, a semiconductor element forming method is configured to have a step of forming a plurality of pin junctions of a silicon-based material on a substrate by a high-frequency plasma CVD process under a pressure of not more than atmospheric pressure, and the method further has a step of forming a p-layer, an i-layer, and a portion of an n-layer of a first pin junction of the pin junctions or forming an n-layer, an i-layer, and a portion of a p-layer of a first pin junction of the pin junctions, and thereafter exposing the p-layer or the n-layer exposed in the surface, to an oxygen-containing atmosphere; a step of forming on the p-layer or the n-layer as exposed to the oxygen-containing atmosphere a layer of the same conductivity type as that of the p-layer or the n-layer; and a step of forming an n-layer or a p-layer of a second pin junction adjacent to the first pin junction to form a pn interface.

An air conditioner comprises a water distributor having an opening on its bottom plate, dams around the opening and inverted U-shaped members with a small space formed between the inverted U-shaped plates and the dams so that water in the distributor is guided by a capillary action and distributed to an indoor heat exchanger. A reservoir is disposed to a pipe system between a pump and the indoor heat exchanger so that drain water in the outdoor drain pan is directed to the indoor heat exchanger through the reservoir. The reservoir has a tube which permits excessive water to spill over an opening of the tube to return to the outdoor drain pan through a returning conduit pipe.
摘要:
An apparatus for forming a non-single-crystal semiconductor thin film comprising a film deposition chamber having a film-forming space surrounded by a film deposition chamber wall and a beltlike substrate, and an external chamber surrounding the deposition chamber wall is provided. While the beltlike substrate is moved in a longitudinal direction, a film-forming gas is introduced through a gas supply device into the film-forming space and microwave energy is radiated from a microwave applicator into the film-forming space to induce a microwave plasma, and thereby form a non-single-crystal semiconductor thin film on a surface of the beltlike substrate. A cooling mechanism and a temperature-increasing mechanism are provided to cover a part of an outside surface of the deposition chamber wall. An apparatus for forming a non-single-crystal semiconductor thin film where the gas supply device comprises a gas manifold set apart from the deposition chamber wall is another embodiment.

A room air conditioner of a window mounted unit type having an air inlet grill and an air outlet grill on a front panel of the air conditioner. The air conditioner has a blower, a heat exchanger and an air passage directing an air flow from the blower to the heat exchanger, and an air guide arrangement in the air passage. The air guide arrangement guides the air flow from the blower to the heat exchanger in a uniform manner to minimize deviation of air flow distribution in the air passage to the heat exchanger.
摘要:
A sputtering method comprising the steps of: arranging the plurality of targets in a vacuum container equidistantly in a transport direction of the substrate such that distances between the plurality of rectangular targets and the substrate are different; and assuming that lengths of sides, parallel to the transport direction, of adjacent first and second targets are expressed as first and second target width W1 and W2, respectively, and that a gap between the first and second targets is expressed as L, when a relationship among the first target width W1, the second target width W2, and the gap L satisfies L≦3(W1+W2), and assuming that a distance from each of the plurality of targets to the substrate is expressed as T, performing sputtering such that a relationship between a longest distance Tmax and the gap L at this time satisfies 0.4≦Tmax/L≦0.8.
摘要:
A method for forming a non-single-crystal semiconductor thin film and a photovoltaic device using an apparatus, which has a film deposition chamber with a film-forming space surrounded by a film deposition chamber wall and a belt-like substrate. An external chamber surrounding the deposition chamber wall is provided in the apparatus. While the belt-like substrate is moved in a longitudinal direction, a film-forming gas is introduced through a gas supply device into the film-forming space and microwave energy is radiated from a microwave applicator into the film-forming space to induce a microwave plasma, and thereby form a non-single-crystal semiconductor thin film on a surface of the belt-like substrate. A cooling mechanism and a temperature-increasing mechanism covering a part of an outside surface of the deposition chamber wall provide temperature control.
