Abstract: PURPOSE:To ensure a large percentage of moisture content, high oxygen permea bility and a long-term continuous use under good feeling by composing a specific (meta)acrylate derivative of a monomer alone or a copolymer obtainable from copolymerization with anther monomer allowing such a process. CONSTITUTION:A (meth)acrylate derivative shown in the formula is a monomer or a polymer (polymer A) obtainable as a result of copolymerization with another monomer allowing such a process. In the formula, R1 stands for a hydrogen atom or a methyl group, and R2 for (CH2)m-, (OCH2CH2)n or the like, where (m) is an integer between 1 and 10, and (n) is an integer between 1 and 15. This polymer A has a triethanol ammonioethyl phosphoric acid group as a phospholipid analogous polar group. The water solubility of the polymer A, therefore, increases, and an anti-fouling property against protein, lipid and the like is provided. Preferably, a mixture of one, two or more types of monofunctional vinyl monomer and cross-linking multifunctional monomer may be used as another monomer capable of being copoplymerzied with the (meth) acrylate derivative A.

IPC: A23L19/20
Filed: 1982-06-16
Abstract: PURPOSE:To obtain a low salt pickled UME, capable of withstanding the stroage for a long term, and nice to health, by desalting a salted UME in water, draining the desalted UME, pickling the UME in a heat sterilized seasoning solution containing an enzyme and a natural mold inhibitor, and semidrying the pickled UME. CONSTITUTION:A salted UME is washed with water or dipped in water and desated to reduce the acid in the flesh to about 2.5-3wt% and salt to about 7- 8wt%. The desalted UME is then drained and pickled in a heat sterilized seasoning solution containing an enzyme and a natural mold inhibitor, e.g. edible vineger or an extract of a natural plant. A natural amino acid, white soy sauce, etc. may be used as the seasoning agent. After pickling fully in the seasoning solution, the UME fruit is taken out of the seasoning soluton and dried by the method of drying in the sun or afrtificial drying, etc. to reduce the moisture content in the UME flesh to about (3/4). Thus, the aimed low salt pickled UME with about 10wt% or less salt capable of withstanding the storage for a long term is obtained.

Title: Thermal transferring film inked ribbon
Inventor: SHIMIZU SUEKICHI
IPC: B41M5/382
Filed: 1984-05-23
Abstract: PURPOSE:To prevent the fused sticking onto a thermal head without providing a sticking preventive layer, by roughening the back surface of a film base material as the sliding surface of the thermal head. CONSTITUTION:For the material of a film base material, for example polyester, polyamide, polypropylene, polystyrene, etc. are taken. Its thickness is within a range of 1-15mum. The back surface of the film base material is roughened by almost uniformly forming a great many of minute projections on the all back surface of the film base material. In that case, they shall be 0.05-1.0mum in average height of projections, 0.1-10mum in average diameter of projections and 10<7>- 10<12> pieces/m<2> in average density of projections. Though the thermal head sliding surface of the film base material is thus roughened, the printing quality is hardly deteriorated and though the film base material itself has not heat resistance, strippability etc. like the sticking preventive layer, the fused sticking onto the thermal head disappears.
