摘要:
A brake includes an annular boot which can be expanded and contracted according to movements of a piston and is assembled to an opening part of a cylinder and to an annular groove on an outer peripheral face of the piston. The boot is assembled by: engaging one end of the boot with the opening part of the cylinder in a state where the piston is contained in the cylinder; moving the piston so that at least a part of the piston is withdrawn from the cylinder and that the other end of the boot is pressed by a pressing face of the piston; and fitting the other end of the boot into the annular groove of the piston, while a movable range of the other end of the boot is restricted by an expanding allowance of the boot whose one end is engaged with the opening part of the cylinder.

There is provided a slider cover for a slide fastener. An upper member and a lower member are spaced apart from each other in an upward and downward direction and arranged in parallel to each other. A connecting post connects the upper member with the lower member. The upper member includes a receiving portion configured to receive at least a part of an upper blade of a slider.

A fastening member contains a synthetic resin, in which flat metal foil containing aluminum is mixed with the synthetic resin and an average particle diameter of the metal foil is set to be equal to or more than 3 μm and equal to or less than 8 μm. Accordingly, the fastening member has both an advantage of a synthetic resin of being inexpensive and light and an advantage of a metal of having strength and gloss having a high-grade sense, and an outer appearance or a texture thereof can be viewed like the metallic member. In the fastening member, a weld mark can be restrained from being generated, and even if the weld mark is generated, the weld mark can be made difficult to be visually recognized relatively and the weld mark can be mixed with the gloss.

The invention provides a fluorescence detecting method, comprising irradiating an excitation light in the UV range on a sample containing a nanoparticle fluorescent material having an emission half-value width of 50 nm to 200 nm as the fluorescent material and detecting the fluorescence emitted from the sample in the visible range.
摘要:
It is an object of the present invention to provide a nanoparticle fluorescent material for detecting cancer with which cancer can be detected with high sensitivity, using highly safe and broad light emission on a simple device. The present invention provides a nanoparticle fluorescent material which comprises a metal-oxide or metal-sulfide nanoparticle fluorescent material whose surface is modified by a surface modifying agent and whose half bandwidth of light emission is between 50 and 200 nm, wherein an antibody that recognizes cancer antigen is bound to the surface modifying agent.
