Abstract: A correction method for a dental cutting machine includes inputting a machining program of a correction piece to the dental cutting machine, mounting a material for the correction piece to the dental cutting machine to which the machining program has been input, machining the correction piece from the material using the dental cutting machine executing the machining program, measuring a dimension of a predetermined portion of the correction piece machined in the machining, calculating a correction value based on the dimension measured in the measuring, and inputting to the dental cutting machine the correction value calculated in the calculating.

Abstract: The present invention provides a light selective transmission filter which selectively shields light and has a high transmittance of light at a specific wavelength such as visible rays, and which has a sufficiently reduced thickness and excellent heat resistance. The present invention further provides a lens unit including such a light selective transmission filter. The light selective transmission filter selectively reducing a transmittance of light has a thickness of less than 200 ?m and includes a base material containing a functional film with reflow resistance. The lens unit includes such a light selective transmission filter and a lens.

Abstract: A route setting device includes a current location detecting section, a transit point setting section, a recommended route calculating section and a transit point determining section. The transit point determining section is configured to determine whether the user selected transit point is a disposable type of transit point and whether the transit point set is a substitutable type of transit point based on the user setting instruction. The recommended route calculating section is configured to calculate a non transit point recommended route without requiring the user selected transit point to be along the non transit point recommended route when the user selected transit point is the disposable type, and an alternative transit point recommended route with the alternative transit point located along the alternative transit point recommended route when the user selected transit point is the substitutable type.
