Title: Manufacture of ceramic burner
Inventor: KUSUDA TAKAO
IPC: C04B35/64
Filed: 1980-09-19
Abstract: PURPOSE: To obtain a burner excellently suitable for diffusion of radiation, etc., by a method in which a ceramic element whose cross section is provided with a large number of flame ports and whose surface is provided with projections by which radiating surface area is increased is baked on a curved pallet in such a way as to curve it along the curved surface of the pallet.  
     CONSTITUTION: The cross section of a ceramic element 1 is provided with a large number of flame ports 2, and also its surface is provided with a large number of projections by which radiating efficiency is raised. When manufacturing a gas burner having a convexed surface by using the element 1, the element 1 is placed on a pallet 4 with a curved surface and then baked in such a way as to curve it along the curved surface of the pallet 4. Thus, a ceramic gas burner A with a convexed surface can be simply obtained without damaging the shape of the flame ports 2 and the projections 3. Also, by using the pallet with a concaved surface, a burner capable of focusing radiant heat can be simply manufactured.

Title: Device for heating sample in vacuum
Inventor: HORI AKIO
IPC: G01N25/48
Filed: 1982-07-27
Abstract: PURPOSE:To make a high temperature limit high and to perform analysis and measurement in a room temperature region, by connecting a power source, which accelerates the electrons discharged from a filament, to the filament, which heats a sample holder, and adjusting a filament current. CONSTITUTION:A sample holder 2, on which a sample 1 is mounted, is heated by a filament 5. Since heat conduction in a vacuum is mainly performed by heat radiation, the upper limit of the temperature of the sample is restricted. A filament heating power source 6 and a power source 7, which heats the discharged electrons, are provided. The temperature of the sample is adjusted by the power source 6. In a low temperature region up to 300 deg.C, a filament current is low, and heating by the bombardment of the electrons is seldom performed even though a voltage 7 is being applied. In a high temperature region, the temperature of the filament is increased and the discharge of the thermal electrons becomes large. Then the sample is heated by the heating based on the electron bombardment and the heat radiation from the filament 5. Therefore, the temperature can be adjusted in the very broad range.

The amt. of the aerating air was planned assuming the utilization rate of oxygen in the aerating air to be 6%. The amt. of charged filthy water was increased during 40 days successively, and normal operation using the charge of planned amt. of water was commenced after two months. By the result of operation by fixing the degree of opening of a flow straightening hole at the bottom of the tank to result a fixed value <=(h + approach speed head at the top of the circulation aeration tank), the passing speed through the flow straightening hole was confirmed to be uniform through the whole length of the tank.
