Abstract: [Problem] Provided are a flying object operating device, a malfunction preventing method for a flying object operating device, a flying object thrust generating device, a parachute or paraglider deploying device, and an airbag device, each capable of improving reliability in terms of safety. A flying object igniter includes an ignition unit, an ignition abnormality detection unit which detects an operating state of the ignition unit, a flight state detection unit which detects a flight state of a flying object, an energizing circuit which has an energizing circuit switch for operating the ignition unit, and a calculation unit which compares a detection result obtained by the ignition abnormality detection unit and a detection result obtained by the flight state detection unit with respective thresholds set beforehand, and turns on the energizing circuit switch in accordance with the comparison result.

Abstract: The present invention provides cell lines capable of indefinite growth which are produced by transforming leukocytes isolated from peripheral blood of fish with a oncogene, a method of establishing the cell line, a method of recovering immunologically active substances from the culture of the cell lines. It has been difficult to maintain continuous cultures of fish leukocytes. The present invention provides cell lines capable of indefinite growth and a method of producing immunologically active substances, e.g., immunologically acitive substances, using these cell lines.

Abstract: A process for the production of food having improved texture is disclosed wherein 0.001 to 5 parts by weight of transglutaminase is added to 100 parts by weight of a food material containing one or more materials selected from the group consisting of fish meat, animal meat and fowl.

Abstract: A lobster-like or crab leg-like food product comprising a muscle imitation part and an outer shell imitation part which envelops said muscle imitation part to be integrated therewith. The process for producing the lobster-like or crab leg-like food product comprises using a pair of molds each having a concave on which is curved an outer shell shape of lobster abdomen having plural segments or an outer shell shape of crab leg.

Abstract: A process for processing and treating raw materials such as marine products comprising of fishes, shellfishes, such as Crustacea and mollusks, and seaweeds or mixtures of said material and an optional mixing additive such as soyprotein, wheat flour and starch by means of a twin-screw extruder. The extrudates obtained by the process have qualities and mouthfeel characteristics different from those of the raw material.

Abstract: Prawn-like food which exhibits a texture closely similar to that of prawns is prepared by adding foamed food starch material optionally containing protein to salted ground fish meat and molding the obtained mixture followed by heating.

Abstract: Green salmon roe, whether it is very fresh or less than fresh, is salted under agitation in a saturated aqueous solution of salt containing a nitrite and being free from any precipitates, and is then dehydrated. The roe thus salted is immersed under agitation in a saturated aqueous solution of malate containing a nitrite and being free from any precipitates. The roe thus processed is worked up in the conventional manner.
