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.

Abstract: An oxygen sensor element made of a ceramic sintered body detects oxygen concentration based on an electric current value measured when a voltage is applied. The ceramic sintered body has a composition formula LnBa2-xSrxCu3O7-? generated by substituting any element selected from group 2 elements in the periodic table, such as strontium (Sr), for a part of a composition formula LnBa2Cu3O7-? (Ln denotes rare earth element and ? is 0 to 1). Sr substitution quantity x should satisfy an inequality constraint 0<x?1.5. This allows provision of an oxygen sensor element that improves durability etc. without losing sensor characteristics.

Abstract: An oxygen sensor for detecting gas concentration based on either an electric current value or a resistance value measured when a voltage is applied to a sensor element includes gaps formed between electrodes arranged in an element main body and ridges where surfaces of an element touch each other. These gaps will be escaping parts for expansion and contraction of electrode material that accompany thermal expansion and contraction of a sensor main body, and concentration of thermal stress at edge parts of the element main body may thus be eliminated, thereby alleviating thermal stress on the oxygen sensor. This allows provision of a gas sensor that controls generation of cracks in the element and that is stably usable over a long period of time.

Abstract: A sensor element has a cross-sectional area that increases either uniformly or gradually from a positive (+) electrode side toward a negative (?) electrode side, thereby leading a hot spot, which attempts to move to the negative electrode side, to a lower resistance side. A position that is at nearly equal distances from paired electrodes formed on either end of the sensor element is set as a hot spot generating position, so as to avoid damage to the electrodes due to heat emitted by the hot spot.

Abstract: A network 50 is hierarchically divided into network devices 501 to 506, areas, and the like to be monitoring targets, and a monitoring device 100 monitors a divided monitoring target. A monitoring device of an N-th layer (here, N?2) that is an upper layer with respect to a first layer monitors information of reachability between user connection points received from a monitoring device of an (N?1)-th layer that is a lower layer and network devices connecting monitoring targets of the (N?1)-th layer making up monitoring targets of the N-th layer and connection statuses between the network devices and areas that are monitoring targets. The monitoring device determines the presence/absence of reachability between user connection points belonging to different monitoring targets of the (N?1)-th layer on the basis of this reachability and the connection statuses.
