IPC: A23L17/00
Filed: 1983-06-28
Abstract: PURPOSE:To deodorize the meat of lamprey in high efficiency without losing vitamin A, and to obtain a material servable as a food, by washing the meat of lamprey with water, and immersing the meat in warm water heated at a temperature to keep the protein from coagulation and containing citric acid, etc. to effect the deodorization of the meat. CONSTITUTION:The body of a lamprey is cut to a length to facilitate the removal of the water-soluble components existing in the body, e.g. about 2-3cm, and the meat is washed with running water to remove the removable water- soluble components. The washed meat is deodorized by immersing, for a definite period, in a dilute citric acid solution heated at <=55 deg.C to prevent the protein from coagulation. The deodorized meat of lamprey retains vitamin A which is the valuable component of lamprey, because vitamin A is soluble in oil and has high resistance to heat. Consequently, the meat can be used not only as a drug but also as a food by cooking.

Abstract: PURPOSE:To use the vapor of etching liquid containing hydrofluoric acid to etch aluminum only, by a method wherein the insulator layer on a metallic wiring is etched by dint of photoengraving process, which insulator layer is formed on one of the principal surfaces of the semiconductor substrates. CONSTITUTION:Alumina (4) is formed on aluminum (3) coated upon the Si substrate (1) and after the photoresist pattern (5) is formed on the surface, it is exposed for several seconds to tens of minutes on the surface of etching liquid containing hydrofluoric acid. Then the overall substrate is covered with the vapor of hydrofluoric acid, but said vapor is difficult to adhere thereto on account of hydrophobic property of photoresist (5) and sticks to the surface of hydrophilc alumina (4) to afford dewdrops (6) of hydrofluoric acid, by means of which alumina (4) is etched and when etching reaches to the surface of Al (3), etching comes to a standstill. It is the reason why the cell formation does not work out and the solvent action of Al (3) could not be promoted, as the underside of substrate (1) has been insulated with Al (3) on the substrate (1) by means of air.
