  • Patent number: 11021807
    Abstract: The purpose of the present invention is to further level the amount of polishing during electrolytic polishing of the inside of a hollow pipe. A holding frame for vertically holding a hollow pipe is pivotally supported on a rack so as to be vertically invertible about the vertical center of the hollow pipe. An electrode is inserted through the hollow pipe and a liquid buffer is disposed on each end of the hollow pipe. A valve mechanism is capable of switching a liquid supply/discharge circuit so as to supply an electrolyte via the liquid buffer positioned at the bottom and discharge the electrolyte via the liquid buffer positioned at the top whether it is before or after the inversion of the holding frame (inversion of the hollow pipe). During an electrolyte supply period before and after the inversion, an electrolytic treatment is as a matter of course carried out for a predetermined length of time. Although said switching by the valve mechanism may be manually performed, a control means may also be used.

  • Publication number: 20210151248
    Abstract: In a coil component, a main body portion is made of a metal magnetic powder-containing resin, and thus a resin component appears on end surfaces of the main body portion. In addition, since external terminal electrodes are made of a conductive resin, a resin component also appears on the surfaces of the external terminal electrodes. Accordingly, insulating coating layers are integrally covered with high adhesion with the end surfaces of the main body portion and the external terminal electrodes by the insulating coating layers coming into contact with the end surfaces of the main body portion so as to straddle the external terminal electrodes.

  • Publication number: 20210135945
    Abstract: An object of the present disclosure is to provide a network device and a method for setting the network device that can, in developing functional modules, perform abnormality detection based on statistical information and setting verification in consideration of a dependency relationship between the functional modules and statistical information and can address a change in a policy in the setting verification and a change in a condition in the abnormality detection. In the network device according to the present disclosure, an existing setting of each module, external information, a dependency relationship, and a policy are collected at one location (setting verification unit) by using a common language. When a new setting is made to the modules, a new dependency relationship is set, or new external information is acquired, the new setting is sent to the setting verification unit and checked against the existing setting, the external information, and the dependency relationship.

  • Patent number: 10344455
    Abstract: Operating information (a pilot pressure, a pump pressure, a hydraulic oil temperature, an engine rotational speed, an hour meter and the like) of a hydraulic excavator and use environment information (operator information) of the hydraulic excavator are transmitted to a center server together with body information (for example, a model, a type, a type number, an identification number and the like) from the hydraulic excavator. For example, when a hydraulic hose as a replaceable component of the hydraulic excavator is replaced, the replaceable component information (a replaceable component name and a replacement date) is transmitted to the center server from a computer for maintenance. The center server predicts a replacement time of the replaceable component (hydraulic hose) using the use environment information of the hydraulic excavator in addition to the operating information and the replaceable component information of the hydraulic excavator.
