A soft-member attachment structure includes an attachment hole provided through a rear end portion of a barrel. The barrel configures a thermochromic writing instrument, along a longitudinal central axis and having an inner circumferential surface between two openings located at an upper end and a lower end; an attachment portion located under a large diameter portion of a soft member used for a thermochromic change and having a diameter being smaller than a diameter of the large diameter portion and allowing insertion into the attachment hole; a straight internal hole provided along a longitudinal central axis of the soft member and opening at least at a lower end of the soft member; and a rod-like inner core having an outer diameter allowing insertion into the internal hole, a length to be placed within the internal hole, and an outer circumferential surface contacting an inner circumferential surface of the internal hole.

There is provided a profile measuring apparatus, including: an irradiation section configured to irradiate a measurement light to a measurement area of the object; an imaging section configured to obtain an image of the measurement area; a table configured to place the object thereon; a coordinate calculation section configured to calculate a position of the measurement area based on an image detected by a detection section; and a positioning mechanism configured to drive and control a relative position of the imaging section and the table. The positioning mechanism calculates a relative position of the imaging section to the table, based on an information with respect to an edge line direction of a convex portion or an extending direction of a concave portion in the measurement area of the object having a repetitive concave-convex shape, to move at least one of the table and the imaging section.

In a reactor vessel () covered by cooling water (), a tubular frame () with a bottom is hung within the cooling water () while still having an air environment in the interior, and the bottom section of the frame () is disposed within the reactor vessel (), thereby achieving an air environment within the reactor vessel (). Furthermore, since repairs to the reactor vessel () are performed by using the frame () while still having the air environment in the interior, this leads to the prevention of contamination and achieves improvements in working conditions such as preventing the generation of dust and reducing decontamination work. Accordingly, repairs can be performed in an air environment without draining the cooling water () within the reactor vessel (), even in a state in which the reactor vessel () is covered by the cooling water ().

Reactor vessel repair method

Provided is an endless operation cord that is easy to replace. The present invention provides an operation cord including: a main cord having one and the other ends; a first coupling part disposed at the one end; and a second coupling part disposed at the other end. The first and second coupling parts can be coupled together directly or via a coupling member and can be coupled or uncoupled by means of a relative rotation between the adjacent coupling parts or between the adjacent coupling parts and coupling member or a relative movement in a direction other than a length direction of the main cord between the adjacent coupling parts or between the adjacent coupling parts and coupling member.

Abnormal states in a high-voltage cable connected to a backlight of a liquid crystal display are detected. This invention includes: a secondary winding of a transformer; a discharge tube connected to the secondary winding of the transformer; means connected to the discharge tube for detecting a tube current; means connected to the secondary winding of the transformer for detecting a transformer current; and abnormal-state detection means for comparing a value of the tube current detected by the tube current detection means with a value of the transformer current detected by the transformer current detection means and interrupting a power supply if a difference greater than a predetermined value is detected. Thus, a case of lighting delayed due to the darkness effect can also be dealt with.
