Abstract: PURPOSE:To prevent the easy melt sticking of an electric contact material by forming an Ag layer to the outer circumference of the title streak, forming discontinuous parts onto the one place or plural places of the outer circumferen tial Ag layer and regulating the sectional area of the outer circumferential Ag layer to the specific ratio. CONSTITUTION:At the time of manufacturing the title material as an electric contact material for medium loads, the molten metal of an Ag alloy contg. Cd and Sn is pulverized by a water atomizing method and is heated in an oxidizing atmosphere to subject Cd, etc., except Ag to internal oxidation; and it is thereafter molded and sintered. Said material is charged into a tube body made of Ag and a lid made of Ag is welded thereto into a composite billet; it is then heated and extruded into a bar shape, is furthermore annealed, is thereafter subjected to wire drawing and is worked into a wire rod having an Ag layer on the outer circumference of the Ag-oxide material. At that time, one or more places of discontinuous parts are provided onto the outer Ag layer and the area of the Ag layer in its section is regulated to 5-35% for the total. The electric contact material for medium loads having no faults of welding in the Ag parts in the use as an electric contact can be obtd.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a reflection type display device such as a reflection type liquid crystal display device using a polarizing plate which solves a problem of display with low reflectance due to the light passing a polarizing plate. SOLUTION: The reflection type display device is composed of a light- transmitting substrate, a prism which is disposed on the back side of the substrate and which has a rugged surface, and a liquid crystal layer which can be converted by electric signals into a medium having at least two different refractive indices, namely, into one state having an almost equal refractive index to that of the substrate and the other state having a higher refractive index than that of the substrate.  The rugged surface of the prism is formed in such a manner that when the medium is in the aforementioned one state, reflection of the incident light from the light-transmitting substrate side is decreased on the interface between the prism and the medium, and that when the medium is in the other state, most of the incident light from the light- transmitting substrate side is totally reflected on the interface between the prism and the medium.

Title: Guided projectile
Inventor: ISOMURA YUKIKO
IPC: F42B15/36
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To eliminate loss of range by separating a ducted engine from the body of projectile after consuming fuel of the ducted engine and following up a target by gliding in low resistance fuselage shape thereby reducing air resistance of fuselage incident to presence of air intake. SOLUTION: A gas generator 6 is loaded into the primary combustion chamber 5 of a projectile and combustible gas is ejected into the secondary combustion chamber 8 through a flow rate controller 7. An air intake 4 takes in an air flow 9 from an air intake 10 and compresses it in an air compression region 11. The high pressure air causes ram combustion in the secondary combustion chamber 8. A sensor 17 sensing the end of combustion in the primary combustion chamber 5 delivers a signal to a separation mechanism 19 through a cable 20 thus unlocking the separation mechanism 19 and a hook 18. Consequently, a ducted engine comprising the gas generator 6, the primary combustion chamber 5, the secondary combustion chamber 8 and the air intake 4 is separated to the rear of the projectile by the air resistance against the air flow 9.

Title: Production of polyaryl ether ketone
Inventor: MATSUMURA SHUNICHI
IPC: C08G65/34
Filed: 1990-10-05
Abstract: PURPOSE:To obtain a high-polymerization degree polyaryl ether ketone excellent in heat resistance and other properties very inexpensively in good reproducibility by reacting a specified aromatic hydroxy halide alkali metal salt by melting through direct heating. CONSTITUTION:An aromatic hydroxy halide alkali metal salt of formula I (wherein X is halogen, Ar is a bivalent aromatic group; and M is an alkali metal) is melt-reacted in the substantial absence of any solvent. Although the compound of formula I can easily be obtained, for example, by uniformly mixing the corresponding aromatic hydroxy halide with an alkali metal hydroxide in an aqueous solution and concentrating and dewatering the mixture, any other process may be adopted. Although the temperature in the melt reaction is not particularly limited, it is desirably in the range from the melting point of the formed polymer plus 10 deg.C to about 420 deg.C. Although the polymerization may be practiced in a reactor provided with an agitator, a process wherein a melt extrusion machine such as an extruder is used is desirable.
