摘要:
A surface processing method for processing the surface of an insulating article in which an ion-implanted surface-modified layer is effectively formed on the article 2. In surface processing the article 2 of an insulating material, an electrically conductive thin metal film 50 is first formed on the article surface. A pulsed voltage containing a positive pulsed voltage and a negative pulsed voltage is applied to the article in a plasma containing ions to be implanted to implant ions in the article surface. This implants ions at right angles to the article surface to generate a surface-modified layer 51. There is no possibility of the article 2 being charged up due to application of a pulsed voltage.
摘要:
A container handling apparatus, a container management system, and a method of container handling are provided in which information of a container to be handled is accurately recognized automatically, in order to improve the efficiency of a container handling operation. An RF-ID reader/writer (wireless communication device) is provided in a container crane, on a beam of a spreader holding the container, facing a lengthwise end face of the container. An RF-ID tag (wireless tag) that stores container information is installed on a lengthwise end part of the container. The construction is such that the RF-ID tag reader/writer performs wireless communication with the RF-ID tag when the spreader is located on the transporting route of the container. The container information includes output of sensors provided on the container that detect security information of the container.
摘要:
Provided are a latent curing agent that gives an epoxy resin composition with improved storage stability and low-temperature curability; and a curable epoxy resin composition prepared by mixing the said curing agent and an epoxy compound. The epoxy resin composition has improved storage stability, and cures at lower temperatures for a shorter period of time than conventional ones. The latent curing agent for epoxy resin comprises two components, (A) a radically polymerized polymer of a monomer having at least a polymerizable double bond, which has at least a tertiary amino group in the molecule, and (B) a polymer having at least a hydroxyl group in the molecule, and forms a solid solution that is solid at 25° C.
摘要:
A vacuum switchgear system, which comprises a plurality of vacuum switchgears each comprising a vacuum container for accommodating the desired number of vacuum switches selected from a disconnecting switch or load break switch, an earth switch and an vacuum circuit breaker. Each of the vacuum switches has connecting terminals. The switchgears constitute different types of switchgears, the switchgears being classified into the power receiving side and power distribution side. The switchgears are connected with the adjoining switchgear or an element selected from an arrester and a PCT by means of an insulated connecting conductor having terminals around both ends thereof. The terminals are electrically connectable with and detachable from the connecting terminals of the switchgears.
摘要:
Fuel vapor in a fuel tank (1) is purged into an intake passage (8) of an engine (10) through a purge vent (2, 4, 6). The controller (21) determines whether a leak is present in a purge vent from the fuel tank (1) to a purge control valve (11). The determination process comprises a pull-down process in which a pressure in the purge vent is reduced using a negative pressure in the intake passage (8) and a leak-down process of sealing the purge vent at the reduced pressure and monitoring the pressure variation. The controller (21) calculates an error equivalence amount (DVPII), a pressure component corresponding to sloshing in the fuel tank (1) during the leak-down process, and determines the presence of a leak in a highly accurate manner based a corrected pressure (DVP5A) in which the monitored pressure variation is corrected using the error equivalence amount (DVPII) (S22).
摘要:
A main circuit switching unit and an isolator are accommodated in a vacuum container. A first conductor and a main circuit conductor are arranged to extend in and out of the vacuum container. A movable electrode of the main circuit switching unit is connected to the first conductor through a first flexible conductor, and a movable electrode of the isolator is connected to the main circuit conductor through a second flexible conductor. A shield is arranged around the first conductor and the main circuit conductor. Another shield is arranged around a connecting portion between the first flexible conductor and the movable electrode of the main circuit switching unit. A still another shield is arranged around the isolator. A further another shield is arranged around the second flexible conductor. These shields are secured to the vacuum container through insulating spacers. This arrangement instantly eliminates a dielectric breakdown phenomenon that occurs at electric field concentrated regions by the shields to prevent a dielectric breakdown caused by particulate foreign matters and thereby improve an insulation reliability of the devices.
