Abstract: A tire vulcanization mold in which a surface roughness in the groove molding portion of the tread molding surface is made smaller than a surface roughness in the land portion molding portion, in which a surface roughness in the groove molding portion is minimized to 0.12 ?m or less in a range including at least a main groove molding portion, and in which a surface roughness in the land portion molding portion is made to be 3.2 ?m or more, is used to manufacture a tire, and when cleaning the tread molding surface, the tread molding surface is irradiated with a laser beam to remove contaminant adhered to the tread molding surface.

Abstract: Provided is a method of performing pre-paint treatment of an automobile body including a high-tensile steel sheet, in which desirable corrosion resistance can be obtained after painting. A method of performing pre-paint treatment of an automobile body, the method including performing an alkaline degreasing step, a first water-washing step, a chemical conversion treatment step, a second water-washing step, and a cationic electrodeposition painting step, in this order, wherein the chemical conversion treatment step is performed using an chemical conversion treatment agent including zirconium (A), free fluorine ions (B), an allylamine-diallylamine copolymer (C), aluminum ions (D), nitrate ions (E) each at a predetermined concentration; the allylamine-diallylamine copolymer (C) forms an acid addition salt having an anionic counter ion, and the pKa of an acid thereof falls within the range of ?3.7 to 4.8; and the content percentage of diallylamine is 80 mol % or more and 98 mol % or less.

Abstract: With the object of preventing deterioration of or damage to a photodetector caused by excessive light by more reliably preventing the excessive light from entering the photodetector, a microscope of the present invention is provided with a high-sensitivity detector, such as an HPD, a GaAsP, an EM-CCD or the like, that detects observation light coming from a specimen, a box-shaped casing that has an opening that allows contained items to be placed therein and removed therefrom and that covers the high-sensitivity detector, a door that can close off the opening of the casing, a switch that restricts light detection by the high-sensitivity detector by turning on and off a drive voltage to be applied to the high-sensitivity detector, and an opening restricting mechanism that allows the opening of the casing in the closed state imposed by the door to be opened only when the light detection by the high-sensitivity detector is restricted by the switch.

Abstract: A coating method according to the present invention includes a step of producing plural exterior members which constitute the outside portion of a vehicle body, and a step of forming and joining plural inside members which constitute the inside portion of the vehicle body, thereby producing a chassis. Each of the exterior members is a precoat metal sheet in which a rust-preventing layer and a coat which contains a lubricating component are formed on a surface of a metal sheet. Accordingly, the exterior members joined to the chassis need only intermediate coating and overcoating. The chassis constituent members are made of a precoat metal sheet in which a rust-preventing layer which contains a lubricating component is formed on a surface of a metal sheet. Accordingly, it is not necessary to carry out electrodeposition coating which is considered to be necessary for the chassis.
