Abstract: To prepare a mineral supplementing agent capable of commonly used for a seasoning liquid, a supplement, a cosmetic, an oral cavity washing liquid, a plant growth promoting agent and the like, by using common materials and a common preparation method. A method of preparing a mineral supplementing agent capable of being administered to a human body or a plant is provided. The method includes a first charging step, a second charging step, a third charging step, a fourth charging step, and an extraction step. The first charging step charges a vessel with part of a prescribed amount of vinegar. The second charging step charges the vessel, which has been charged with the vinegar, with at least one of garlic, instant coffee, vinegar, and a fruit. The third charging step charges the vessel, which has been subjected to the second charging step, with at least one of a particulate grain hull, a charred product thereof, and a calcined ash thereof, and mixing the contents of the vessel.

Abstract: An electric power transmitting device transmits electric energy from one coil to another coil through an inductive coupling therebetween. One of the coils has an end bent in the axial direction of the coil. When the other coil is to be inserted into said one coil, it can be inserted in not only the axial direction of said one coil, but also a direction transverse to the axial direction through the bent end of the coil. Said one of the coils is typically housed in a holder, and the other coil in the grip of a gun-shaped, hand-held bar-code scanner. When the grip is inserted into a groove defined in the holder, the coils are magnetically coupled to each other, thus providing an inductive coupling. The bar-code scanner can easily be placed on and removed from the holder.
