Title: Ink jet recording device
Inventor: JINNAI KOUICHIROU
IPC: B41J2/09
Filed: 1979-06-11
Abstract: PURPOSE:To accelerate the deflection of printing charged drops, prevent the aggregation of ink drops and increase the printing accuracy by inserting an insulating plate between a recording head and a deflecting electrode and providing a charge electrode shielded at its periphery with an insulating material or a shielding plate. CONSTITUTION:A charge electrode 3 is shielded by insulating materials 10 and 11 and a shielding plate 12 to prevent the dischargeing between the charge electrode 3 and deflecting electrodes 4 and 4', and to make it possible to provide both electrodes at positions close to each other. The deflection of printing charged drops charged through the hole 9 of an insulating plate 8 is accelerated, and charging of non- charged drops due to the influence of the deflection voltage can be prevented. By rendering the deflecting electrode 4 into a minus high potential and the deflecting electrode 4' into a ground potential, an accelerating force is acted on the printing charged drops and a decelerating force on the noncharged drops thereby to prevent the aggregation of the ink drops.

Abstract: PURPOSE:To improve the uniformity of the magnetic field of the title solenoid magnet by a method wherein the current running on an interlayer transition lead wire 7 is changed into reverse direction. CONSTITUTION: The coil 2 of each layer is divided into the lower layer group 3 and the upper layer group 4 consisting of the same number of layers, the winding direction of the coil 2 is set in the reverse direction by the unit of group, both ends of the coil 2 of each layer are cut, and they are led out by a lead wire 5, and each coil 2 is connected in series using transition lead wires 7 and 8 in such a manner that the direction of current running on the coil 2 of the lower layer group 3 and the direction of current running on the coil 2 of the upper layer group are reversed each other. As the winding direction of the lower coil group 3 and the upper layer group 4 are reversed each other, and the direction of current is also reversed, the magnetic field formed by the coil 2 of both groups 3 and 4 become the same direction. Also, as the current running on both groups 3 and 4 become reverse direction with each other, the direction of current of the transition lead wire 7 between the groups 3 and 4 becomes reverse with each other. As a result, the magnetic field is cancelled by the lead wire 7, and no effect is given to the center magnetic field.

Title: Amorphous silicon solar cell
Inventor: KOSHIYOU NOBORU
IPC: H01L31/048
Filed: 1980-06-02
Abstract: PURPOSE:To prevent the deterioration of the characteristics of the solar cell having an amorphous Si active layer by shielding a light incident plane by a layer which absorbs only the light whose wavelength is substantially about 0.4mum or less. CONSTITUTION:In the amorphous Si which is grown by a glow discharge of SiH4, many junctions of Si-H are formed. But their arrangement is irregular and unsaturated electron pairs of Si are very few. Therefore the locat level density is small. The efficiency can be improved by adding impurities of II and V groups and by controlling valence electrons. The dissociation energy of the Si-H junction corresponds to the energy of photons whose wavelength is 0.38mum. When the light whose wavelength is 0.38mum or less is inputted into the solar cell whose active layer is amorphous Si, the characteristics are gradually deteriorated. Therefore, triazole series compounds and the like are added to resin 4 of silicone and the like which is filled in the space between the incident plane of cell elements 2 and a protecting glass 3, and ultraviolet ray whose wavelength is 0.4mum or less is absorbed. Then the dissociation of Si-H junction can be avoided, and the deterioration of the characteristics can be prevented.

Title: Solar cell
Inventor: UCHIDA YOSHIYUKI
IPC: H01L31/04
Filed: 1980-06-02
Abstract: PURPOSE:To absorb most of solar energy and to utilize both electric and thermal energy by providing a semiconductor layer which performs only light to heat conversion and has a narrower inhibition band below a photoelectric conversion layer. CONSTITUTION:An N<+> amorphous Ge layer 2 is formed by a glow discharge of PH3+GeH4 on a stainless steel 1. Then, an N layer 31, an I layer 32, and a P layer 33 are sequentially layered by the glow discharge of SiH4, and a photoelectric conversion active layer 3 is constituted. A transparent conducting film 4 of ITO and a grid shaped current collecting electrode 5 of Al are formed. When solar light is inputted into the film 4, the light whose wavelength is 1.3mum or less is absorbed by the layer 2. This wavelength lies in the region whose wavelength is 0.8mum or more which is not abosrbed by the layer 3 wherein the width of inhibition band is 0.95eV. As a result, about 85% of the solar energy is abosrbed by the layers 2 and 3. The energy absorbed by the Ge layer is transformed into heat. The heat transformed from part of the energy which is abosrbed by the Si layer 3 is also taken out of the substrate 1. The heat is utilized through a heat exchanger. In this constitution, the energy utilizing ratio is enhanced.
