Abstract: Zinc (II) ions (zinc sulfate, zinc acetate and the like) originated in inorganic salts making it difficult for such ions to pass through biological membranes, thus being difficult to be incorporated in a human body. For overcoming such problems, it is necessary to develop food products with a prophylactic effect against diabetes, which contain zinc sources and have a lower toxicity than zinc (II) ions, a good stability and good fat-solubility. The present invention provides food products which have a prophylactic effect against diabetes using specified health foods, nutritional (functional) foods or the like containing natural substances that contain zinc in high concentrations (plants such as papaya, maca and the like, and yeasts such as baker's yeast, brewer's yeast and the like).

Abstract: A tuner circuit includes a variable attenuator circuit including a PIN diode, disposed upstream of a variable-gain amplifier circuit and controlled according to the same AGC voltage used to control the variable-gain amplifier circuit. The operations of the variable-gain amplifier circuit and the variable attenuator circuit in relation to the AGC voltage are set such that when an input RF signal is at a maximum assumed level, a direct current that flows through the PIN diode will be less than a value of a direct current that maximizes intermodulation distortion.

Abstract: An inexpensive sheet with excellent evenness and a desired uniform thickness can be obtained by cooling a base having protrusions, dipping the surfaces of the protrusions of the cooled base into a melt material containing at least one of a metal material and a semiconductor material for crystal growth of the material on the surfaces of the protrusions. In addition, by rotating a roller having on its peripheral surface protrusions and a cooling portion for cooling said protrusions, the surfaces of the cooled protrusions can be dipped into a melt material containing at least one of a metal material and a semiconductor material for crystal growth of the material on the surfaces of the protrusions. Thus, a sheet with a desired uniform thickness can be obtained without slicing process.
