Title: Production of poly-beta-alanine polymer
Inventor: YAMAMOTO FUMIHIKO
IPC: C08G69/00
Filed: 1986-08-12
Abstract: PURPOSE:To obtain quickly a poly-beta-alanine polymer of a high degree of polymerization and uniform quality, by forming a mixture of acrylonitrile with a catalyst into a layer of a uniform thickness and polymerizing the monomer by heating in the absence of oxygen. CONSTITUTION:In the production of a poly-beta-alanine polymer by the hydrogen transfer polymerization of acrylamide, a mixture of acrylamide with a catalyst is formed into a layer of a uniform thickness and the monomer is polymerized by heating in the absence of oxygen. Although an alkali (alkaline earth) metal alcoholate, can be mentioned as an example of the catalyst used, calcium dipropylate is particularly desirable when the obtained polymer is used as a heat stabilizer for polyacetal resins. Although the amount of the catalyst used is usually selected from the range of 1/30,000-1/30, the catalyst is used preferably in an amount in the range of 1/30,000-1/500 in order to obtain a poly-beta- alanine polymer of a high degree of polymerization.

Inventor: SUZUKI MASAKO
IPC: C25D21/04
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a micrometallic globe peels and scatters from a substrate by executing bubbling by an inert gas before and in the process of plating. SOLUTION: This micrometallic globe is the one in which, before or after immersion in a soldering soln., the plating soln. is bubbled by an inert gas, and while the bubbling is furthermore executed, electroplating is applied to provide the outer circumferential face of the globe with soldering coating having a prescribed thickness. The above bubbling is the one in which, e.g. an inert gas such as nitrogen is introduced from the bottom part of the plating bathtub to substitute it for dissolved oxygen in the bath, and the flow rate of the inert gas is preferably regulated to 50 to 1000ml/min.  By regulating the dissolved oxygen content to <=2ppm by this bubbling, in cooperation with the bubbling in the electroplating, the amt. of gaseous H2 occluded into the soldering coating formed on the surface of the metallic globe can be reduced to the utmost, and as a result, swelling is not generated in the plating coating in the case of being mounted on a package board under heating, and the peeling and scattering of the micrometallic globe can be prevented.

Title: Diaphragm for speaker
Inventor: OKUZAWA KAZURO
IPC: H04R7/02
Filed: 1990-07-16
Abstract: PURPOSE:To enhance the elastic modulus and to improve the fragile property by using a thermoplastic liquid crystal polymer as major component and forming a meandering groove on the surface of a metallic die. CONSTITUTION:When a thermoplastic liquid crystal polymer 5 is heated, it is molten and the viscosity is decreased and an excellent fluidity is represented and when the polymer is injected in a metallic die of speaker diaphragm shape by injecting molding, the polymer 5 is cooled and solidified while being orientated on the inner surface of the metallic die. In this case, since the direction of the fluidity of the liquid crystal polymer 5 is meandered on the inner surface of the metallic die by forming a meandering groove 3 locally on the inner surface of the metallic die, the orientation of the liquid crystal polymer 5 is meandered. Thus, the elastic modulus for the speaker vibration is enhanced and the fragile property of the diaphragm for the speaker is improved.

That is, a metallic fine particle having catalytic action is carried on highly crystallized graphite or an amorphous carbon particle of the fiber surface, and when heat treatment is performed in an oxidizing atmosphere, since the particle is corroded and sunk inside at an extremely low temperature substantially in response to the particle size, electrons can easily pass through the Ag particle 2, and electron loss can be reduced.

When the CuO in the reactor 3 loses the H2 removing capacity, the film 2 of the detector 5 becomes CuO Cu2O Cu and the face that the electric conductivity is varied is detected. The detection is carried out during unmanned operation of the refrigerator and safety operation is carried out by changing over the reactor 3 to a preliminary device 13 because 0.1ppm H2 concentration can be detected.
