A pneumatic ratchet wrench includes a driving head, a feeding path, a primary path, a secondary path, a valve member, and a trigger. The anti-reflection film comprises a low refractive index layer that is formed by mutually binding hollow fine particles, each of which has a vacancy therein, using a binder, and the low refractive index layer consists of a first layer serving as an outermost layer and a second layer which is adjacent to the first layer and is located on the substrate side. The buffer silicon oxide film can be reliably removed when the gate insulating film is formed, because no nitride film is made between the substrate and the buffer silicon oxide film. There is also information in the ASICs that is common to them for the tag. The method improves the efficiency and convenience of isolating nucleic acids from FFPE tissue samples.
