Abstract: The cool air inside a refrigerator compartment 2 is introduced through a return opening 10 into an ion generation chamber 45 provided behind the refrigerator compartment 2. A voltage is applied to a needle-like electrode 11a arranged in an upper portion of the ion generation chamber 45 so that, by corona discharge, positive and negative ions are discharged substantially parallel to the cool air circulating in the direction indicated by arrow B2. This helps alleviate the loss of ions resulting from collision with a wall surface, and permits the ions to reach a wide area. This prolongs the period for which the cool air is kept in contact with the ions, and thus helps enhance the sterilizing effect.

Abstract: A delay factor in a processing in a job system in which an ordered series of jobs are executed in computers assigned to respective jobs, is efficiently detected, and the delay factor is analyzed in detail by associating it with load information of the computers and a network. An administrative manager computer 201 collects a history of executing a job from each job executing computer 202, and refers to a history of each job, one by one from a job executed later to a job executed earlier, until no delay is detected in a job, for judging a cause of delay in each job. Further, with respect to a job in which delay is detected, load statuses of the other jobs or applications in the computer in which said job is in execution are compared with said job and displayed.

Abstract: An elasto-plastic damper adapted to be used in a structure for absorbing vibration energy created by earthquake tremors and other ground vibrations. The damper is formed from flat plates to simplify design and to minimize costs. The damper may be used in combination to absorb vibration energy impacting the structure from different directions.

Abstract: An elasto-plastic damper is adapted to be used in a structure, such as a building and other facilities, for absorbing vibration energy created by earthquake tremors and other ground vibrations. The damper is a centrally bulged and generally cone-shaped hollow body of revolution so that its section modulus changes substantially porportional to a bending moment created in the damper body due to horizontal stresses, thus permitting a maximum degree of deformability. This elasto-plastic damper is compact in size and demonstrates a high degree of vibrational energy absorbability.

Abstract: A composite metal material for a friction brake composed of a sliding friction surface metal layer of grey cast iron and a layer of a high strength different metal having a crack transmission resistance. The grey cast iron and high strength different metal are metallurgically bonded together. In this composition metal material, cracks formed in the sliding friction surface metal layer are prevented from spreading by the high strength different metal having a high crack transmission resistance. An intermediate metal layer may be provided if desired.

Abstract: An oil-containing waste water treating material, comprising an active carbon upon whose surface is chemically bonded at least one nitrogenous compound which is an amine or a quaternarized derivative thereof.

Abstract: The present invention relates to improved heat insulating particles with a high heat insulating effect and high mechanical strength. The particles are smooth cells formed around hollow or solid grains of a low heat-conducting material such as silica, alumina, glass, or a synthetic resin like nylon or teflon, which are coated with a material that can readily reflect the heat radiation such as aluminum, copper, gold, silver, stainless steel or titanium. The cells thus-formed are bound together by sintering in the form of a block or any other desirable shape so that the metallic surface cells are bonded together at their points of contact through molecular dispersion of the metal molecules of the respective surfaces.
