摘要： PURPOSE:To reduce the level of noise, produced by the rotation of a cross flow fan, for which the number of its blades and the number of the revolutions are responsible, while maintaining the volume of air flow, by bending more deeply the arcuately peripheral outer side of the fan blade. CONSTITUTION:Although the mounting angle theta of the blade 11 of a cross flow fan 12 is the same as that formed conventionally, the end part on its outer peripheral side is bent by a dimension 1 through an angle alpha. By the selection of the optimum dimension and angle for such a fan device, as for the air flow characteristic, the conventional flow volume can be maintained and, as to the noise characteristic, the level of noises produced by the fan rotation becomes 5dB and thus can be made lower than the conventional noise level by 8dB. This can reduce the level of noise, produced by the rotation of the cross flow fan 12, for which the number of its blades 11 and the number of the revolution are responsible, while maintaining the volume of air flow.

摘要： PURPOSE:To obtain the title composition which cures at low temperature in a short time by mixing an epoxy resin, a synthetic rubber, a phenolic resin, a noble metal compound catalyst, and a photosensitive aromatic onium salt. CONSTITUTION:The title composition which contains, on a solids basis, 15-40wt.% epoxy resin, 40-60wt.% synthetic rubber, 20-40wt.% phenolic resin, 0.01-2wt.% noble metal compound serving as the catalyst for chemical plating (e.g. fine particles of an inorganic filler containing, e.g. adsorbed palladium chloride, or a resin solution containing, e.g. dispersed palladium chloride), and 0.2-5wt.% photosensitive aromatic onium salt (e.g. triphenylphenacylphosphonium tetrafluoroborate). Because of the curability at low temperature in a short time, the use of this composition can give a printed wiring board which scarcely suffers the warping and torsion of the substrate, has a plating with high peel strength, and has high resistance to soldering heat.

摘要： PURPOSE:To bypass gas from a first stage inlet to a nest stage inlet to which no foreign material is adhered in an expander composed of a plurality of expansion stages by forming a bypass line for compressed gas from the inlet of one expansion stage to the inlet of the next stage, in the case that foreign material is adhered only to the first stage. CONSTITUTION:In the case that a sectional area of a flow passage for gas is decreased through adhesion of foreign material to a blade of the first stage 1 of an expansion machine pressure is increased in the upper course of a turbine inlet line 8. A bypass line 3 having a valve 12 is therefore arranged. Pressure increase is prevented by feeding compressed gas through the bypass line 3 to a second stage inlet nozzle 6 at the second stage 2 of the next expander. Performance deterioration is prevented at the second stage 2 of the expansion machine to which no foreign material is adhered. Performance deterioration of whole of the expansion machine is suppressed to minimum.

摘要： PURPOSE:To obtain a printed wiring board having a wiring pattern with high peel strength and having high resistance to soldering heat by using as supporting base material a polyester film having the surface treated with an olefin to render releasable in an adhesive film for chemical plating which consists of an adhesive layer and a supporting base material and employing the obtained adhesive film for manufacturing a printed wiring board. CONSTITUTION:An adhesive film for chemical plating consisting of an adhesive layer and a supporting base material, wherein a polyester film having one or both of its sides, in contact with the adhesive layer, treated with an olefin to render releasable is used as the supporting base material. It is desirable that the surface of the adhesive layer be covered with a protective film having less adhesiveness to the adhesive layer than to the support film. For the adhesive layer, a phenolic resin, an acrylonitrile/butadiene copolymer, an epoxy resin, and a compound containing a photosensitive aromatic onium salt can preferably be used.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioner in which generation of noise due to collision of air flow from an axial fan against the fins of a heat exchanger is reduced. SOLUTION: A heat exchanger is provided with a mesh-like plate at a part where the distance to a fan is shortest. Air passed through the mesh-like plate generates a trace turbulence and the direction of air flow passing through the fins of the heat exchanger is altered thus reducing generation of nose at the fins.

摘要： PURPOSE:To provide an air cleaner capable of efficiently creating a comfortable environment in a room. CONSTITUTION:An air cleaning section 3 consists of a dust collector 5, a deodorizer 6 and a firs air fan 7 which makes a draft through those devices, and an oxygen-enriching section 4 is composed of oxygen enriching membranes 8, a vacuum pump 9 and an second air fan 10 which draws a draft through those devices. The second air fan 10 takes in air from a space where the first air fan 7 sucks and discharges air or an another space, supplies air onto the surface on one side of each oxygen enriching membrane 8, and delivers the oxygen-enriched air, which is obtained by reducing pressure on the other sides of the oxygen-enrichment membranes 8, into an air supply duct of the first air fan 7. The air which does not permeate the oxygen-enriching membranes 8 and is low in oxygen concentration is discharged to a space other than the space where the first air fan 7 sucks and discharges air. Thereby, as the total amount of cleaned air is returned into a room, air cleaning is efficiently carried out and the oxygen-enriched air having a high oxygen concentration is delivered along with the cleaned air.
