A particle collector system includes a dust collection unit, a power source unit, and a capacitance measurement unit. The dust collection unit includes first and second electrodes, a second electrode, and a dielectric body covering the electrodes. The power source unit supplies power source voltage to the first and second electrodes. The capacitance measurement unit measures the capacitance between the first and second electrodes. With this particle collector system and dust collection method using it, particles can be almost completely removed without periodic performance of a particle removal operation.

Particle collector system and dust collection method

There is provided a bonding material capable of forming a bonding body under an inert gas atmosphere such as a nitrogen atmosphere, and capable of exhibiting a bonding strength that endures a practical use even if not a heat treatment is applied thereto at a high temperature, which is the bonding material containing silver nanoparticles coated with a fatty acid having a carbon number of 8 or less and having an average primary particle size of 1 nm or more and 200 nm or less, and silver particles having an average particle size of 0.5 &#x3bc;m or more and 10 &#x3bc;m or less, and an organic material having two or more carboxyl groups.

A lip cosmetic applicator device () including an applicator () for applying a cosmetic () to a lip and a receptacle () for containing the cosmetic (). The applicator () is withdrawable from and insertable into the receptacle through a neck () of the receptacle (). The applicator () includes a stem () and an applying portion () connected to one end of the stem (). The applying portion () is a flattened shape and has an applying side (A) for applying the cosmetic (). When viewed from the front, the applying portion () has a widest part (E) and gradually decreases in width from the widest part (E) to a tip thereof. The applying side (A) of the applying portion () is a concave surface having a concavity (C) in a center thereof.

Lip cosmetic applicator device

This cosmetic application device () includes an application tool () and a container (), the application tool () being insertable into and removable from the container () through an opening () of the container (). When the application tool () is tilted in a state where the fixation between the lid body () of the application tool () and the mouth/neck section () of the container () has been released and the lower end section () of the lid body () is located at a position within the height-wise length of the mouth/neck section (), the front end of the application section () of the application tool () is made to contact an inner wall in the vicinity of the bottom section of the containing section () of the container ().

Cosmetic application device

The method for manufacturing a silver particle-containing composition according to the invention is directed to a method for manufacturing a silver particle-containing composition coated with a fatty acid and includes a step (A) of preparing silver particles coated with a first fatty acid (a) with 3 to 7 carbon atoms, a second fatty acid (b) with 2 to 20 carbon atoms, and a solvent in which the first and second fatty acids can disperse, respectively, a step (B) of adding the silver particles coated with the first fatty acid (a) and the second fatty acid (b) into the solvent, and a step (C) of substituting the second fatty acid (b) for the first fatty acid (a) coating the silver particles after the addition step.
