Title: Photocatalytic filter
Inventor: UCHIUMI YOSHIHARU
IPC: A61L9/00
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To emit a light sufficiently deep inside and thereby fully exhibit the photocatalytic performance of a deodorizing material as a whole by integrally combining an adsorbing material borne on the surface and the interior of a photocatalyst with a light waveguide path which guides an excited light to the photocatalyst to form a photocatalytic filter. SOLUTION: A microparticular powder of TiO2 is added to and dispersed in a silica sol prepared by dissolving a tetraethoxysilane in ethanol and adding a mixed solution of water, nitric acid and ethanol. Further, a fibrous activated carbon is soaked in this dispersion and is removed from the dispersion to be dried and baked and consequently, a TiO2 bearing fibrous activated carbon unwoven fabric 1 is obtained. A platelike filter comprising alternately laminated sheetlike light waveguide paths 2 consisting of a bundle of guarty fibers and the unwoven fabric 1, is built in a closed circulation-type gaseous phase reaction device. In addition, acetoaldehyde is circulated through the filter while ultraviolet rays are irradiated from the end face of the light waveguide paths 2. Thus, it is possible to efficiently emit an excited light from outside the filter to the inside photocatalyst, so that the performance of the photocatalyst can be fully exhibited.

Title: Solid electrolyte oxygen meter
Inventor: SHIMONO MASARU
IPC: G01N27/409
Filed: 1980-08-26
Abstract: PURPOSE:To prevent accuracy for measurement from being effected by gas to be measured that leaks from the fixing part for a partition and a holder, by inserting a gas suction pipe with its opened inlet into the inside of the holder in an oxygen meter that measures the oxygen concentration in a high-temperature gas when inserted into various furnaces. CONSTITUTION:A cylindrical partition 1 with one end closed comprising a solid electrolyte having oxygen ion conductivity is installed to a cylindrical holder 5. Inside the partition 1 a reference gas introducing pipe 7 is opened and inside the  holder 5 a gas suction pipe 8 is opened. Since the gas suction pipe 8 is opened inside the holder 5 in this way, a positive gas flow from the side of the partition 1 toward the side of the holder 5 can be formed. Through the process, it is possible to  prevent a gas mixture between gas to be measured leaking from the fixing part for  the partition 1 and the holder 5 into the partition 1 and reference gas introduced into the partition 1 from contacting with a reference electrode 2, further since only  the reference gas contacts always with the reference electrode 2, higher measuring  accuracy is obtained.

Title: Driving mechanism of running truck
Inventor: TOMARU TAKATOSHI
IPC: B66C9/14
Filed: 1989-05-10
Abstract: PURPOSE:To improve accuracy of stopping a truck in a fixed position by rotating a sprocket to move the truck through a chain which is linked over the full running area of the running truck. CONSTITUTION:A drive sprocket 20 is rotated, for instance, in the clockwise direction. Since a chain 34, whose both ends are fixed, is wound and linked, a truck 10 is moved leftward along a rail 18 by rotating the sprocket 20. Here because a rotation of the drive sprocket 20 is completely transmitted to the chain 34, the truck 10 is moved simultaneously with starting of a motor 24. When the truck 10 reaches a predetermined position, the rotation of the sprocket 20 is stopped by a brake while stopping the drive motor 24. Thus a position of the truck 10 is restricted by the chain 34, so that the truck is surely stopped without slipping on the rail. Further, any adjusting work, after the truck is stopped, is not required.

     CONSTITUTION: The horticultural house (or green house) is heated by a suitable heater in winter. In this case, the air in the hothouse is heated to a high temperature so that it becomes necessary to adjust the humidity in the hothouse without spoiling the high temperature atmosphere in the hothouse by introducing the open air into the hothouse. To meet such requirement, the heat exchanger for supplying and discharging the air into, and from, the hothouse is provided in a part of the hothouse. The heat exchanger has the heat transfer walls formed of the multilayered thin plates of a metal, a synthetic resin or a fiber material and the air passages which are formed of the gaps 5 and 6 among the thin plates and which cross one another in an alternative fashion. Thus, the open air 7 supplied into the hothouse exchanges heat with the air 4 in the hothouse. In this case, the air 4 is forced to be discharged outside the hothouse by a fan 3 and the open air 7 is introduced naturally into the hothouse.
