A beverage straw-containing device includes: a generally circular-shaped beverage container lid; a generally circular-shaped beverage container; and a bendable or flexible straw, the straw being ring-shaped, coiled, or angled in its storage position and removably encased within, or detachably attached directly or indirectly to, the beverage container lid andor the beverage container. The present invention relates to a virtual waveplate that is used to replace a birefringent waveplate. A transmissionreception unit performs data transmissionreception for the video communication. After forming alloy with the semiconductor by heat treatment to form ohmic contact, a strip of aluminum is formed on one side of the die on the front side for wire bonding and to be the positive electrode of the LED. The expanded tubular section is axially extended by moving the remaining tubular section downward relative to the expanded tubular section so that said lower end portion of the wall bends radially outward and in axially reverse direction. The frequency generation section selects a frequency signal in synchronism with a timing generated by the timing generation section.
