An antenna unit includes a substrate (120), an antenna (110) located on one major surface of the substrate (120), a dielectric plate (130) opposed to the major surface of the substrate (120), and a dielectric layer (190) interposed between the substrate (120) and the dielectric plate (130). The dielectric plate (130) has a dielectric constant of not more than the dielectric constant of the substrate (120). The dielectric layer (190) has a dielectric constant smaller than the dielectric constant of the dielectric plate (130).

摘要:
The present invention provides preventive and/or therapeutic agents for either one, or both, of a diabetic vascular disorder and a diabetic respiratory disorder comprising, as an active ingredient, a cyclohexenone long chain alcohol compound represented by the following formula (1): [wherein R1, R2, and R3 each represent a hydrogen atom or a methyl group, and X represents a linear or branched C10-C28 alkylene or alkenylene group].Since the cyclohexenone long chain alcohol of formula (1) improves diabetic vascular smooth muscle contraction and bronchial smooth muscle contraction, it is useful as a preventive and/or therapeutic agent for a diabetic vascular disorder or a respiratory disorder.
摘要:
According to the radio receiver, a first path P1 included in a frequency conversion circuit 12 does not have a filter, and a filter 171 for extracting a reference signal 74c is provided in a second path P2 so that a second IF multiple signal 74 and the reference signal 74c are multiplied together in a mixer section 12a. Consequently, by extracting the reference signal 74c, the filter 171 in the second path P2 operates as a local oscillation signal source synchronized with the second IF multiple signal 74. Therefore, according to the signal obtained by down-conversion of the second IF multiple signal 74 with use of the reference signal 74c in the mixer section 12a, signals identical in quality to input signals inputted on the transmission side can be reproduced.
