Title: Antenna circuit
Inventor: MAEDA TAKEYASU
IPC: H01Q7/00
Filed: 1990-11-19
Abstract: PURPOSE:To miniaturize an antenna circuit so as to be easily produced and to obtain a wide band characteristic by folding toward the ground surface and a feeder section one end of a conductor surface that is used as the antenna element and connecting the tip of the conductor surface to the other section of the conductor surface so as to form a loop. CONSTITUTION:Ene ond (d) of antenna element 11 is folded to the metallic case, to a feeder section, and further folded inside twice so that the tip of the antenna element 11 connects the antenna element at a position farther from the feeder section for antenna element 11 to form an antenna loop. The upper surface (e) of the metallic case 3 acts as the ground surface. GaP D2 between the folded section (d) of antenna element 11 and the upper surface (e) of metallic case 3 generates a capacity, and if the folded section (d) and the upper surface (e) have the same resonance frequency, the area of the capacity is reduced. Further, since the area that generates the capacity is wide, the gap may be made large and the dimension precision becomes moderate. Furthermore, since a loop is added to the tip of the antenna element, the change in reactance relative to the resonance frequency becomes moderate and the band characteristic spreads over a wider band.

Title: Fluorescent lamp
Inventor: AKEBOSHI MINORU
IPC: H01J61/28
Filed: 1988-12-12
Abstract: PURPOSE:To prevent decay of light flux because of shift of amalgam by fitting a glass member, amalgam, and another glass member one after another in a thin tubing of a light emitting tube.

Title: Flat plate type solid electrolyte fuel cell
Inventor: TOMITA NOBUYOSHI
IPC: H01M8/12
Filed: 1986-12-26
Abstract: PURPOSE:To make it possible to fabricate a large scale, high output cell with long life, low cost material by using one or two of an interconnector, an oxygen electrode, and a fuel electrode to increase the thickness. CONSTITUTION:An oxygen electrode 1, a solid electrolyte 2, and a fuel electrode 3 are stacked in an interconnector 4 to form a cell.

A current path 9 in the inter-connector 4 is the half of gas supply passage width 10 and electric resistance is decreased. Therefore, the cell can be formed with perovskite oxide containing Sr or Fe which is long life and excellent as construction material although conductivity is somewhat low. By this method, a large scale, high output cell can be fabricated at low cost.

IPC: H04N5/765
Filed: 1995-11-09
Abstract: PURPOSE: To prevent vignetting from occurring in the case of photographing operation and to appropriately expose a recording medium at all times. CONSTITUTION: An image is formed on an electronic developing type recording medium 30 by a photographing optical system 12.

Title: Power device for burning fuel on fluidized bed
Inventor: PIITAA DEII HARUTEBERUTO
IPC: F23C10/30
Filed: 1988-12-14
Abstract: PURPOSE: To prevent slag limps formed in a bed material from penetrating into a conduit for returning the bed material back to a combustion chamber by providing a storage container for receiving/supplying the bed material from/to the combustion chamber upon fluctuation of load with a sieve or a grate. CONSTITUTION: The bed level 30 is lowered when a load is reduced by opening a valve 46 such that gas flows out from a space 66 in a storage container 32 to the atmosphere thus decreasing the pressure. Since a pressure difference is produced between the space 66 and a combustion chamber 12, gas and bed material flow from the combustion chamber 12 to the container 32 through a conduit 34. The bed level 30 is elevated when the load is increased by opening a valve 54. Air in a space 18 having a pressure higher than that at the orifice of an L-shaped valve 38 activates the valve 38 to return the material in the container 32 back to the bed. A sieve pipe 58 prevents slag lumps 64 from choking the outlet from the container 32 or clogging a return conduit 36.
