Title: Manufacture of solar battery module
Inventor: YAMADA SATOSHI
IPC: H01L31/048
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To reduce deformation and damage to an photovoltaic element, breakage of coating material, and waviness of a solar battery module, etc., even when a rough photovoltaic element is coated, by compressing a member of flexural rigidity from outside, and coating the photovoltaic element with a front surface coating material and a rear surface coating material. SOLUTION: Outside a front surface coating material 105 and/or a rear surface coating material 106, members 109 and 105 which elastically deform in thickness direction and members 110 and 104 of flexural rigidity are piled up in order, and then pressurizing from the outside the members 110 and 104 of flexural rigidity, a photovoltaic element 107 is coated with the front surface coating material 108 and the rear surface coating material 106. Then, with the members 109 and 105 which elastically deform in thickness direction provided, deformation and breakage of the photovoltaic element 107, and breakage of the coating material are prevented.  In addition, since pressure is applied through such members 110 and 104 as comprising flexural rigidity, the surface of a laminate material does not deform more than the member which elastically deforms in thickness direction, no large waviness occurs.

Title: Thermionic oscillation generators, particularly adapted for use in television receivers
IPC: H03K4/43
Filed: 1936-01-06
Abstract: 449,743. Valve generating circuits; television. HAZELTINE CORPORATION, 15, Exchange Place, New Jersey, U.S.A.- (Assignees of Lewis, H. M.; 4700, Forest Drive, Douglaston, New York, U.S.A.) Jan. 6, 1936, No. 463. Convention date, Feb. 9, 1935. [Class 40 (v)] A saw-toothed oscillation generator is " snapped " into and out of operation by the regenerative action of an auxiliary valve, which is so adjusted that the regenerative effect is stronger when an applied synchronizing impulse is weak, and vice versa. As shown in Fig. 1, a condenser 1 is charged through a variable resistance 3 (which may be replaced by a pentode valve) and discharged through a valve 4 under the control of a synchronizing impulse from a source 20 applied to the resistances 13 and 8 in series. When the voltage across the condenser 1 reaches a value where current starts to pass through the valve 4, the voltage drop across the resistance 8 throws the grid of the auxiliary valve 9 negative and reduces the current through its output resistance 16. This in turn throws the grid 7 of valve 4 more positive, and so accelerates the discharge of the condenser. As the discharge current falls off, the back-coupling between the valves 4 and 9 acts in the reverse fashion to increase the impedance of the valve 4 and allow the condenser 1 to recharge. The synchronizing impulse is applied from a tapping on the resistance 13 to the grid of the auxiliary valve 9. By shifting the tapping point, the coupling voltage between the two valves can be weakened as the strength of the applied synchronizing impulse increases or vice versa. The resistance 13 may be inserted in series with the anode of the valve 9 and the backcoupling tap taken to the grid of the valve 4. Fig. 3 shows a similar synchronizing control applied to a back-coupled valve 5 arranged to produce sinusoidal waves of a frequency determined by the tuning of the circuit 26, 27. The Specification also describes the invention as applied to a complete television receiver.

Title: Method of producing monocrystalline semiconductor material
IPC: C30B25/02
Filed: 1963-01-04
Abstract: <PICT:0998211/C6-C7/1> Monocrystalline semi-conductor material, such as germanium, is produced from a gas phase by exposing a substrate to a stream of gas containing molecules which include reducible atoms of the semi-conductor material, at a temperature at which the molecules adhere to the substrate surface but do not decompose, and then reducing the atoms of the molecules adhering to the substrate surface followed by epitaxial growth, on the reduced atoms, of additional semi-conductor material from the gas until the desired thickness is obtained.  In one embodiment, Fig. 1, germanium tetrachloride in a dry deoxidized hydrogen stream, in a concentration of about 0.1 mol per cent, is passed over a quartz substrate 23, heated to 500  DEG C., producing an adherent film of HGeCl3.  The film is reduced to a germanium film in dry, deoxidized hydrogen at 650  DEG C. and the quartz surface is then exposed to a stream of GeCl4 in H2, as before, together with 0.001 mol per cent of boron tribromide at 500  DEG C. to deposit epitaxially P-type germanium on the germanium-coated quartz surface.  The flow of BBr3 is interrupted and a stream of PCl3 is substituted, growing an additional epitaxial layer of N-type germanium.  Other possible dopant sources are AsCl3 and AsBr3.  A further embodiment, Fig. 3 (not shown), utilizes an intermediate oxidation step providing a mask for producing epitaxial growth on selected areas. In this case an anodized molybdenum or tungsten substrate is provided with a polar gas film by exposure to SiCl4 gas in H2 at between 730-910  DEG C., which is then reduced to silicon in a hydrogen stream at 950  DEG C., so producing a silicon film on the anodized surface. The silicon film is then oxidized to SiO2 by exposure to water vapour or oxygen and, after selective etching in hydrofluoric acid, epitaxial growth through the masking pattern is continued, providing a film of HSiCl3.  BBr and subsequently PCl3 gases are introduced at this stage, providing the necessary doping to form p-n junctions.
