Abstract: A magnetic shield structure having openings, the structure comprising a plurality of similar magnetic blind bodies 2, each blind body 2 having an imaginary blind core plane F and a plurality of magnetic material slats 1 being spaced from each other by a distance d required for magnetic shielding, each slat 1 intersecting the blind core plane F at a longitudinal central axis C thereof, the longitudinal central axes of the slats are oriented substantially in parallel to each other on the blind core plane F. The blind bodies 2a, 2b are coupled in a row by serially coupling each slat 1 in each blind body 2a to a corresponding slat 1 of adjacent blind body 2b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2a, 2b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2a, 2b form openings in the magnetic shield structure.

Abstract: When an antenna switching unit selects a first antenna and a reference gain does not exceed a first limit value, a gain of a variable amplifier is set to the reference gain. When the antenna switching unit selects the first antenna and the reference gain exceeds the first limit value, the gain of the variable amplifier is set to the first limit value. When the antenna switching unit selects a second antenna and the reference gain does not exceed a second limit value, the gain of the variable amplifier is set to the reference gain. When the antenna switching unit selects the second antenna and the reference gain exceeds the second limit value, the gain of the variable amplifier is set to the second limit value.

Abstract: A drum type washing machine operates based on two washing processes. In the first process, a drum-shaped spin basket is rotated by 50 R.P.M. in forward and backward directions. Next, in the second process, the spin basket is rotated by 300 R.P.M. during about 20 seconds. Thereby, washing water contained in textiles is dewatered to outside of the spin basket. These first and second processes are repeatedly by specified times.
