Abstract: The present invention relates to nutritionally enriched maple syrup, which is enriched in vitamins, and more particularly to nutritionally enriched maple syrup which contains vitamin C in an amount of 50 mg or more based on 100 ml of maple syrup obtained by thermally concentrating a maple sap. The present invention also includes maple syrup enriched in vitamins such as vitamin E and vitamin B1 and other nutrients. According to the present invention, the nutritional value and quality of maple syrup, particularly maple syrup obtained by thermal concentration, can be improved and the range of its use for other foods can be widened. Nutrient enrichment can be carried out by an efficient method suited for industrial scale production. Moreover, the nutritionally enriched maple syrup of the present invention exhibits a well-balanced flavor, and thus it can be widely added to various foods.

Abstract: A shrinkage prevention agent for water washing of clothing that would conventionally have been dry cleaned. The shrinkage prevention agent is compromised of a steam or vacuum dry-distilled liquid of two or more plants selected from sagebrush, beefsteak plant, tea, plantaginales, aloe, chrysanthemum, pine, cedar, cypress. The shrinkage prevention agent is used in a wet cleaning system that includes water washing.

Abstract: There are provided a valve which is opened by an improved two-step motion, a valve which operates positively without leakage of fluid even when the difference in pressure between inlet and outlet of the valve is very small, and an improvement of a solenoid valve using those valves.The present invention relates to small-sized opening/closing valve and solenoid valve capable of being operated by very small force and electric power using a dry cell or the like, and is suitable to a solenoid valve for automatic opening/closing control which is used in city gas appliances, etc.

Abstract: An anti-freezing device for use in water supply conduits, which includes a driving chamber for imparting a drive to a main valve which is moved by the volumetric expansion due to the freezing of water therein so that the main valve is separated from a valve seat thereby to discharge water in the conduit outside therethrough. The flowing movement of water in the conduit prevents it from freezing.
