A sigma-delta modulator includes a plurality of quantizers, an input path, a feedback path, a loop filter, a pre-filter, and a connection path. The plurality of quantizers are configured to produce a plurality of quantized signals. The input path is configured to lead an input signal to the plurality of quantizers. The feedback path is configured to feed back a feedback signal into the input path, and the feedback signal is produced by averaging the plurality of quantized signals. The loop filter is put on the input path before the plurality of quantizers, and the loop filter is configured to receive the input signal and the feedback signal. The pre-filter is configured to output a signal to a corresponding quantizer which is one of the plurality of quantizers.

A method for preparing a spring roll involves putting an ingredient material on a dough sheet of the spring roll, rolling up the dough sheet to wrap the ingredient material, and frying the rolled spring roll. A food material containing a main component selected from polysaccharides, powders of grains and mixtures thereof is attached to 40% or more surface area of the dough sheet based on a total surface area of the dough sheet of the spring roll before the spring roll is fried.

Processed foods made of iodine-enriched wheat flour contain 0.05 mg to 40 mg of iodine per 100 g of wheat flour. The iodine is provided by blending small quantities of residues of extracts from sea weeds in the Laminaria group into wheat flour used for the production of such processed foods as bread, cakes, cookies, noodles, and the like. It is possible to intake essential iodine easily without any sense of incongruity.

A method of improving water retention characteristics of soil by using water absorption polymer, including the steps of forming a water impermeable layer in a subsurface layer of the ground, and providing a water absorption polymer layer in an upper region of the water impermeable layer. The method is executed by an apparatus for forming a water impermeable layer in a subsurface layer of the ground, the apparatus also being used to mix water absorption polymer in the soil in an upper region of the water impermeable layer, by an injecting apparatus having a drilling function.
