Title: Cable connector having noise filter
Inventor: SENDA MASAKATSU
IPC: H01R13/719
Filed: 1994-03-16
Abstract: PURPOSE:To provide a connector which is simple and flexible and enables effectiveness to a noise in several hundreds MHz or higher frequencies by constituting a part or the whole of a cage body or a pin receiving part out of a magnetic substance. CONSTITUTION:A connector is composed of a cage body 2, a pin receiving part 3, electrodes 4, electrode holes 5 and a cable inserting hole 6, and the electrodes 4 are insulated from each other. The cage body 2 is composed of a magnetic substance. Ferrite can be used as the magnetic substance. Even if a part of the pin receiving part 3 or the cage body or only a part of the pin receiving part 3 is composed of ferrite, it functions as a noise filter. Even if the magnetic substance formed by mixing powder or grains of ferrite in a nonmagnetic substance such as plastic is used as a part or the whole of the cage body 2 or the pin receiving part 3, it functions as a noise filter. Since an spurious electromagnetic wave is radiated in the circumferential direction from a lead wire, a cable, a cable end and the electrodes, it is more effective to arrange ferrite around the peripery of at least a single member of the lead wire, a cable wire or the electrodes.

Filed: 1979-06-12
Abstract: PURPOSE: To raise the compressiblity of steel powder by controlling N-pick-up at a specifically small amount in the manufacture of a Cr-stainless steel powder for a powder metallurgical raw material.  
     CONSTITUTION: A Cr-stainless steel powder containing 0.04% C, 0.5W2.0% Si, 0.6% Mn, and 11W21% Cr is melted in an atmosphere of Ar gas and then atomized by water to manufacture a steel powder for powder metallurgy, where the intrusion of air is completely shut out and N-pick-up is suppressed to control the content of N to 0.03% or less. Or, besides the said composition, one or two or more of ferrite- forming elements, e.g., Mo, Ti, V, Zr, Nb, Sn, etc., may be added. By lessening the amount of austenite-forming elements, e.g., C, N, etc., as much as possible, the formation of residual austenite can be suppressed and the use of the material as a raw material for powder metallurgy enables one to make the density of sintered product higher because of its excellent compressibility and thereby to raise the hardness and toughness of the product.

This group is inputted to a fault processing device 5 and then collated with a fault processing method sotred in a fault processing storage device 4 to decide on a processing method. Then, the decided processing method is displayed 6 to an operator. Thus, the processing method for a fault in a nuclear plant, etc., is determined adequately in a short time.

Title: Preparation of composite damping steel plate
Inventor: MATSUMOTO YOSHIHIRO
IPC: F16F15/02
Filed: 1989-03-24
Abstract: PURPOSE:To prepare a composite damping steel plate excellent in both of weldability and adhesiveness by a method wherein a liquid resin is applied to metal plates so that the sum coating thickness of the resin in a dry state becomes a specific ratio with respect to the particle size of a filler to be dried and the resin coating surfaces of the metal plates are subsequently bonded under pressure to each other. CONSTITUTION:The upper and lower steel plates 4, 5 uncoiled from steel plate coils 1, 2 are coated with liquid resins on the upper surfaces thereof by resin coating devices 6 to be passed through drying ovens 7 to evaporate the solvents of the resins. The steel plates 4, 5 are bonded at the coating surfaces thereof under pressure by a heating roll group 8 to bond the resin surfaces thereof mutually and large bonding strength can be obtained. The resins are applied so that the sum thickness of the resins applied to the steel plates 4, 5 becomes a ratio of 0.8-1 with respect to the particle size of a filler after the drying of the resins. When the sum thickness of the resins is a ratio of below 0.8 with respect to the particle size of the filler, the resin thickness is relatively insufficient and no desired bonding strength can be obtained. When said sum thickness exceeds a ratio of 1, the steel plates can not be directly brought into contact with the filler and, as a result, conductivity is lowered and weldability is damaged.
