摘要:
A writing implement, wherein elements forming a reverse flow prevention mechanism are formed in rather simple shapes and assembly process for the reverse flow prevention mechanism is rather simplified. The reverse flow prevention mechanism (19) comprises a valve chamber (54b), an inflow port (55) opened to the ink storage part (16) side of the valve chamber (54b), an outflow port (56) opened to the writing tip (17) side of the valve chamber (54b), a valve element (57) stored in the valve chamber (54b), a restricting body (58) stored in the valve chamber (54b) at a position on the outflow port (56) side of the valve element (57), and a valve seat (54c) formed around the inflow port (55). When the writing tip (17) is faced upward, the inflow port (55) is closed by the valve element (57), and when faced downward, the valve element (57) is allowed to touch the restricting body (58) and does not reach the outflow port (56).

The present invention provides an annealed wafer which has a wafer surface layer serving as a device fabricating region and having an excellent oxide film dielectric breakdown characteristic, and a wafer bulk layer in which oxide precipitates are present at a high density at the stage before the wafer is loaded into the device fabrication processes to give an excellent IG capability, and a method for manufacturing the annealed wafer. The present invention is directed to an annealed wafer obtained by performing heat treatment on a silicon wafer manufactured from a silicon single crystal grown by the Czochralski method, wherein a good chip yield of an oxide film dielectric breakdown characteristic in a region having at least a depth of up to 5 μm from a wafer surface is 95% or more, and a density of oxide precipitates detectable in the wafer bulk and each having a size not smaller than a size showing a gettering capability is not less than 1×109/cm3.

The ink bag is structured as follows: To the respective long side portions (1a, 1b, 2a, 2b) of a rectangular-shaped, thermally fusible first film forming the surface portions (1, 2) of the ink bag, there are attached, by thermal fusion, the long side portions of a rectangular-shaped, thermally fusible second film forming the side surface portions (3, 4) of the ink bag and having lower rigidity than the first film to thereby form a cylindrical body. The one-side short side portions (1c, 2c) of the surface portions of the ink bag are attached together by thermal fusion to form a bag body. An ink supply hole forming member (5) is attached by thermal fusion to the other-side short side portions of the surface portions of the ink bag. In the four corners of the ink bag, there are formed band-shaped connecting portions (6 to 9) each starting from one of the two mutually adjoining sides of the ink bag and reaching the other of the two sides.
