Abstract: A double-gate field-effect transistor includes a substrate, an insulation film formed on the substrate, source, drain and channel regions formed on the insulation film from a semiconductor crystal layer, and two insulated gate electrodes electrically insulated from each other. The gate electrodes are formed opposite each other on the same principal surface as the channel region, with the channel region between the electrodes. The source, drain and channel regions are isolated from the surrounding part by a trench, forming an island. Gate insulation films are formed on the opposing side faces of the channel region exposed in the trench. The island region between the gate electrodes is given a width that is less than the length of the channel region to enhance the short channel effect suppressive property of structure.

Abstract: An electronic delay circuit for firing an ignition element. The delay circuit includes a capacitor which stores electric energy supplied from an electric blasting machine, an oscillator generating a clock pulse train, a circuit for over-exciting the oscillator, a counter which counts clock pulses of the clock pulse train, and a circuit for maintaining a reset state of the counter for a predetermined time period after the electric energy is supplied. The counter produces a trigger signal when it counts a predetermined number of the clock pulses, and the electric energy stored in the capacitor is discharged to the ignition element. Since the oscillator enters into the steady state in a very short time by the over-excitation, the delay circuit has large resistance to external noise.

Abstract: The composition comprises highly nutritious powder of gourd fruit which is available as solid nutritious food or nutritious beverages. The gourd powder composition contains the powder of gourd fruit, creaming syrup and/or L-ascorbic acid. The other nutritious ingredient can be added if necessary. When supplied as beverages, the foaming agents can be added thereto. The L-ascorbic acid is used mainly for the purpose of removing the grassy-smelling peculiar to the gourd. The creaming syrup is used to have the powder of gourd fruit deflocculated in the liquid. If the foaming agents are added thereto, the powder of gourd fruit is more easily deflocculated in the liquid and the cooling beverage like cream soda can be made.
