Patent JP-H0697190-A (JP)
Title: Manufacture of mos transistor
Inventor: IMAI KENJI
IPC: H01L29/78
Filed: 1992-09-17
Abstract: PURPOSE:To stop an etching at the time of the exposure of a protective film under a sidewall material layer and thereby prevent a gate electrode and the surface of a substrate from being unnecessarily etched by depositing the sidewall material layer, having an etching rate higher than that of the protective film, on the protective film covering the gate electrode and semiconductor substrate. CONSTITUTION:An impurity region 16 is formed in a silicon substrate 11 using the gate electrode 15 thereon as a mask. The surface of the gate electrode 15 is oxidized by heating to form an oxide film 17, and then a nitride film 18 is formed to cover the gate electrode 15 and silicon substrate 11. An silicon oxide layer is deposited thereon, and unisotropically etched to form a sidewall 20. At that time damage to the gate electrode 15 and surface of the silicon substrate 11 is prevented. Finally, impurity ions are implanted again, using the gate electrode 15 and sidewall 20 as a mask, to form an impurity regions 21 to serve as the source and drain.

Title: Preparation of resin-coated carrier
Inventor: NEGISHI HIROAKI
IPC: G03G9/113
Filed: 1988-09-30
Abstract: PURPOSE:To prevent a resin-coated carrier from generation of coagulated matters by prepg. slurry by dispersing a core material for a carrier in a soln. contg. a coating resin in a solvent, then charging the slurry into another solvent which is easily soluble in said first solvent but insoluble for the coating resin under stirring, then removing both solvent components. CONSTITUTION:A solvent B which is easily soluble in a solvent A constituting a resin soln. but insoluble for a resin component is selected, and a resin soln. contg. dispersed core material for the carrier is charged to the solvent B under stirring. By this method, the solvent A contg. dissolved resin components diffuses into the solvent B, but incompatible resin component with the solvent B covers the surface of the core material for the carrier and is fixed thereto. Since this phenomenon proceeds quickly and uniformly on the surface of individual particles, covering layers of uniform thickness are formed efficiently. Both solvents A, B are removed thereafter, and the produce is then dried. Thus, generation of coagulated matters is prevented.

Title: Laminated pressure vessel
Inventor: TANAKA HIROSHI
IPC: B32B7/02
Filed: 1987-10-02
Abstract: PURPOSE:To improve operating efficiency of vessel wall members by forming a pressure vessel as a laminated pressure vessel consisting of laminated plural vessel-shaped layers, and radially and evenly distributing the stress generated in the vessel wall by specifying the apparent elastic moduli of each vessel-shaped layer. CONSTITUTION:When a cavity 11 of a laminated pressure vessel 11 is filled with a high pressure fluid, the fluid pressure of the fluid acts on an alloyed vessel 12 so as to enlarge the diameter of the vessel 12, and thus to produce stress in the vessel 12. The stress in the vessel 12 further acts on a reinforcing layer 13 closely contacted with the vessel 12 so as to enlarge the diameter of the reinforcing layer 13, and thus to generate stress in the reinforcing layer 13. However, for the laminated pressure vessel 11, the apparent elastic modulus of the vessel 12 on the high pressure side is about one-half smaller than that of the reinforcing layer 13 on the low pressure side, so that the stress generated in the vessel 12 is greatly reduced.

Title: Method for diffusion of liquid
Inventor: KAWABE MASATO
IPC: B01J4/00
Filed: 1987-10-05
Abstract: PURPOSE:To form easily a flow with a uniform distribution of velocity, by installing a distribution plate which causes a large pressure loss in a fluid passage to eliminate the presence of dead zone when fluids are diffused from a fluid inlet into a passage having a larger sectional area. CONSTITUTION:A distribution plate 2 is disposed in a fluid passage in a diffuser 1 so that the pressure drop caused by the fluid when it passes through the distribution plate 2 is much larger than that caused by the fluid when it flows radially outwardly through the space 3 between the plate 2 and a fluid inlet 5. The distribution plate 2 is made of porous plate of sintered metal etc., having pores with a diameter of 3-7mum, while the depth of the space 3 is made 5mum-1cm to make the pressure loss within the space 3 sufficiently small. As a result, on both sides of the distribution plate 2, no change in concentration of the fluid occurs and the fluid does not separate from said plate, causing a good piston flow of the fluid thereafter.
