A shock-absorbing elastic sheet comprises a single sheet of elastic material having a flat sheet-like base portion and a large number of semispherical protrusions integral with and projecting from one surface of the flat base portion. The semispherical protrusions are arranged in direct contact with one another such that every adjacent three or more of the semispherical protrusions jointly define a valley therebetween. The sheet-like base portion has a large number of breathing holes formed therein, each of the breathing holes being located at a position corresponding to the position of one of the respective valleys. A cushion pad produced from the elastic sheet, a sole insert and a shoe in which the cushion pad is incorporated are also disclosed.

To provide protein drug sustained-release microparticle preparations for injection that in the production thereof, minimize the use of organic solvents and avoid the simultaneous use of an organic solvent immiscible with water and an aqueous solution and that with respect to the obtained product, simultaneously have in vivo disappearing and sustained-release capabilities, slowly release the contained protein drug at a substantially constant rate over a period of three days or more and realize a drug content of 5% or more, excelling in dispersibility and needle passability; and to provide a process for producing the same. The protein drug sustained-release microparticle preparations for injection comprise a porous apatite or derivative thereof containing a protein drug and, provided thereon by coating or adhesion, an in vivo disappearing polymer.

The present invention provides an ISDN-containing patch that causes minimal occurrence of skin rash and has excellent percutaneous absorption and adhesive strength. The present invention discloses an isorbide dinitrate-containing patch comprising: an adhesive layer formed on a flexible support, wherein said layer comprises an adhesive composition containing adhesive and isosorbide dinitrate, the adhesive being composed of silicone-based adhesive (A) and polyvinyl acetate-based adhesive (B), their weight ratio being A:B=85:15 to 15:85, and the weight ratio of isosorbide dinitrate (C) to the adhesives (A+B) being (A+B):C=90:10 to 60:40.

A navigation system for a vehicle enables an operator to know a calculated optimal path from a starting point to a destination before departure. After the optimal path is calculated, a preview function allows the operator to sequentially view the calculated optimal path either prior to departure or at any point along the optimal path. A cancel function allows the operator to cancel a displayed portion of the optimal path and to request calculation and display of an alternate optimal path which does not employ the canceled portion of the original optimal path.

A nuclear reactor internal pump has a pump shaft connected to a motor and rotatably passing through the bottom of a nuclear reactor pressure vessel, an impeller fitted to a front end portion of the pump shaft, a diffuser disposed on the downstream side of the impeller and having an inner cylinder fixed to the bottom of the reactor pressure vessel to surround the pump shaft, a purge water passage defined between the pump shaft and the inner cylinder to communicate with the inside of the reactor pressure vessel and a purge water supply device for supplying purge water to reactor pressure vessel through the passage. Further, the nuclear reactor internal pump comprises a clad dropping preventive device for trapping clad coming from the reactor pressure vessel in the passage to prevent the clad from dropping.
