Abstract: Disclosed is a pharmaceutical composition comprising pitavastatin, or its salt or ester and MgO, of which the aqueous solution or dispersion has pH of from 10 to 10.8. The composition has good time-dependent stability and has no change in its outward appearance even after having been stored long.

Abstract: A rearview mirror includes a housing, a frame, a front and a rear glass members retained between the housing and the frame. The front and the rear glass members are sealably bonded together in a spaced-apart relationship to define a chamber receiving an electrochromic medium. The front glass member made of strengthened glass has a higher mechanical strength than the rear glass member made of ordinary glass. When an external force exerts on the rearview mirror, the rear glass member functions as a strain relief device to absorb the striking energy of the external force, thereby preventing the front glass member from being broken.

Abstract: A quick open-closed device for biochemical equipment (1) comprises a socket (2) disposed on the biochemical equipment and a plug (3) for coupling with the socket. The socket is a hollow, cylindrical element, and comprises a cylindrical sidewall (25) and a passage (26) in communication with an interior chamber of the biochemical equipment. The cylindrical sidewall of the socket defines an engaging slot (27), which comprises a guiding portion (271) and a retaining portion (272) connected with each other.

Abstract: A method for drying wafers after a wet bench process is disclosed. In the method, a wafer is first immersed in a volume of DI water held in a container. A mixture of alcohol vapor/inert gas is then flown into the upper portion of the container that is not filled with the volume of DI water at a flow rate of less than 20 l/min. The wafer is then withdrawn from the DI water into the upper portion of the container filled with the alcohol vapor/inert gas mixture and thereby driving DI water molecules off the surface of the wafer without leaving organic residue on the wafer surface.
