Abstract: A phenol resin-impregnated sheet formed by impregnating a porous resin sheet with a phenol resin having a degree of cure of from 70% to 95% is arranged on and lamininated to the surface of a carbon fiber-reinforced thermosetting resin sheet. The thickness of the phenol resin impregnated sheet is between 0.01 mm and 1.0 mm. A very even, strong and water-proof wood reinforcing material is obtained. The wood reinforcing material is intergrated and cured on the surface of the wood material by the phenol resin-impregnated sheet to reinforce wood material (single board or bonded board) to form a reinforced wood material. The wood reinforcing material adheres suitably with the wood material and does not cause environmental contamination.

Abstract: A plurality of pieces of medical equipment each of which includes a microcomputer and has a program used to control the microcomputer stored in a reproqrammable storage device such as an EEPROM is linked to a remote computer over a communication line. Using a rewriting/updating program sent from the computer, each piece of medical equipment rewrites or updates the program stored in the storage device. When a plurality of programs is stored, if one of the programs is rewritten or updated abnormally, the other program is used to activate medical equipment.

Abstract: For the purpose of automatically vending cups of cold drinks, ice being directly put into a cup, source powder or a concentrated source liquid, and cold water are required for mixture. Ice is made by an ice making machine. Cold water is prepared by cooling city water with ice made by the ice making machine. To that end, a cylinder for stocking ice formed of apertures at a portion of the peripheral wall thereof for allowing a flow of the water therethrough and a cold water tank for storing cold water around the cylinder are provided. Ice made by the ice making machine is selectively supplied into a cup for vending or into the ice storing cylinder for the cold water. The cold water is held in the cold water tank and is withdrawn through the ice storing cylinder while the same is in contact with the ice stored therein. The cold water is mixed with the source powder or the concentrated source liquid and the mixture is guided to a cup together with the ice.
