Filed: 1990-03-12
Abstract: PURPOSE:To obtain the subject nonwoven fabric having excellent stretchability, softness and elastic recovery and suitable for wadding of sports wear, etc., by mixing specific latent crimping conjugate fiber and easily splittable conjugate fiber. CONSTITUTION:(A) A latent crimping conjugate fiber having a crimp number of <=18/25cm before heat-treatment and >=50/25cm after heat-treatment is produced by combining a polyethylene terephthalate component with a component produced by copolymerizing ethylene terephthalate with 5-sodium sulfolsophthalate. Separately, a polyester is combined with a polyolefin to obtain a splittable conjugate fiber B wherein a part of both components is exposed to the surface of the fiber and both components are split from each other by heat-treatment. The fibers B are blended with the fibers A, the mixture is formed in the form of a web and the product is heat-treated to obtain the objective nonwoven fabric.

IPC: G05B9/03
Filed: 1984-03-30
Abstract: PURPOSE:To improve the reliability by multiplexing the whole of a control device including a selecting circuit which selects controller outputs. CONSTITUTION:If controllers 1A-1C are normal, their output signals are equal to one another, and Sa Sb Sc S0 is true. Even if one of these controllers becomes abnormal in this state, output signals are not changed from S0 because two input signals to selecting circuits 2A-2C coincide with each other approximately. For exmaple, if the selecting circuit 2A becomes abnormal, an output signal S1 and signals Sb and Sc are inputted to the selecting circuit 2B, and S0 is selected as the output signal of the selecting circuit 2B because of Sb Sc  S0. Consequently, the contact of a switch T1 is opened, and the output signal S1 of the selecting circuit 2A is not adopted, and an output signal S3 of the selecting circuit 2C is outputted as a process control device output signal S.

Title: Combustion device
Inventor: MIURA KAZUO
IPC: F23D11/40
Filed: 1980-05-07
Abstract: PURPOSE: To prevent the production of a gas with noxious offensive smell at an initial stage of combustion, by a method wherein a catalyst oxide placed at a downstream side of a liquid fuel main burner in a combustion device for a hot air heater, is heated from its upstream side by means of a fuel burner, and combustion by a main burner is then conducted.  
     CONSTITUTION: A gas fuel auxiliary burner 21 is ignited at a combustion starting time, and acatalyst oxide 20 at a downstream side is heated to rapidly raise its temperature to a temperature at which oxidation reaction can be caused. Simultaneously, an vaprizing tower 22 is heated by means of a heater 25 and also receives the heat radiated from the burner 21. This heats the vaporizing tower quickly to a temperature at which a liquid fuel can be gasified steadly. A main fuel burner is then burnt. This enables the main burner to be rapidly brought into a steady combustion state, and additionally, when combustion starts, a gas having a noxious offensive smell, produced resulting from the combustion simultaneously, is oxidated by the catalyst oxide action to be converted into innoxious gas.

Abstract: PURPOSE:To carry out a stable polishing operation by holding abrasive grains by means of the surface tension or adhesion of a liquid and reducing the liquid content of a compression molded liquid-bond grinding wheel, making a liquid stay on a surface, and pressing a material to be polished against it to carry out polishing. CONSTITUTION:The mixing ratio between abrasive grains and liquid is optionally set so as to obtain a convenient condition for the operations of mixing, compression, molding, etc., and this mixture is compression molded and treated to reduce the contained liquid, increasing the physical strength to obtain an effective liquid-bond grinding wheel. This liquid-bond grinding wheel is mounted on a polishing device, a liquid is sprayed or poured on its surface to make the liquid stay on the surface, and a material to be polished is pressed against it and made relatively slide. Thereupon, the liquid penetrates the fine spaces of the abrasive grains and, finally, the liquid is stopped on a face including the mutual contact points of the abrasive grains, providing a funicular zone in which the liquid continuously exists. Hence, by adjusting the quantity of liquid which is fed to the surface, a most favorable mixing condition can be set, enabling a stable polishing operation.

Abstract: PURPOSE: To decrease leaking of light from a core layer and to decrease optical transmission loss by specifying the pitch of roughness on the side face of the core layer larger than the pitch of roughness just after the side faces are etched. CONSTITUTION: A core glass layer is formed on the surface of a glass substrate 1 which constitutes the lower clad layer, and a specified mask pattern is formed on the core glass layer to etch the glass layer. Then the mask pattern is removed to obtain the core layer 2 on the glass substrate 1. The core layer 2 as formed is heat treated so that the rough state with a small pitch on the side faces of the core layer 2 produced by etching is smoothened to increase the pitch of roughness to a size enough larger than the wavelength of light. Then glass particles are deposited to cover the core layer 2 and heated to vitrify to form an upper clad layer 3. Thus, the pitch of the rough surface on the side face of the core layer 2 is made larger than the pitch of the rough surface just after etching.
