A graphics map of an area in which a system is set is displayed on a screen of a display unit, and minimized stations and line connecting between the stations are displayed on the map. Display colors of the station icon and the line icon are changed in accordance with presence/absence of a failure. When each station icon is clicked, a window showing a list of NODEs belonging to that station is opened, and a NODE having a failure and a NODE having no failure are also distinguished from each other by changing the display colors in this window.

A method for the mass production of interferon, wherein cultured cells are brought into contact with at least one polyhydric alcohol, thereby achieving a remarkable increase in the production of interferon from the cultured cells.
摘要:
A method is provided for assembling a combination shock absorber and air spring including a tubular shock absorber having an outer tube and a piston rod reciprocably projecting from one end of the outer tube, and an air spring consisting of a resilient diaphragm member having an outer wall portion connected to a cylindrical housing secured to the projecting end of the piston rod, an inner concentric wall portion secured to the outer tube, and a rolling wall portion formed between the inner and outer wall portions. The method comprises the steps of expanding radially outwardly and rolling back one end portion of a tubular resilient diaphragm member to form the outer wall portion and the rolling wall portion, fitting a retaining ring on the inner surface of the outer wall portion, fitting the tubular resilient diaphragm member on the outer tube of the shock absorber and securing the other end portion of the diaphragm member thereto, and securing the outer wall portion of the cylindrical housing by utilizing the retaining ring.
摘要:
An electric rotary machine having a superconducting rotor, such as a dynamoelectric machine. A cylindrical shielding member is provided for protecting the superconducting winding from the influence of the magnetic flux of the stator, and for shielding the heat radiated from the normal-temperature side of the machine, thereby maintaining the superconducting winding at an extremely low temperature. An inner reinforcing body and an outer reinforcing body are fitted to the inner and the outer peripheral surfaces of the cylindrical shielding member so as to reinforce the latter. These reinforcing bodies are effective to reduce the stress in the rotor caused by the centrifugal force and electromagnetic force during a running of the electric rotary machine, thereby protecting the shielding member against breakage and/or deformation.

A bandpass filter includes a multilayer body, which includes a plurality of dielectric layers stacked on top of one another, a first inductor and a second inductor connected in series with each other, and a third inductor connected to a connection point between the first and second inductors, and a ground potential. The first inductor is defined by substantially open-loop-shaped first electrode patterns provided on the dielectric layers being superposed with one another in the stacking direction of the multilayer body. The second inductor and the third inductor are defined by second electrode patterns and third electrode patterns provided on the dielectric layers being superposed with one another in the stacking direction.
