    摘要: A phenolic chelate resin comprising the three-dimensional product obtained by cross-linking a phenolic compound represented by the general formula (I): ##STR1## (wherein M is an alkali metal atom, an ammonium group, or a hydrogen atom, and R.sub.1 and R.sub.2, which may be the same or different, each is a hydrogen atom or an alkyl group having 1 to 3 carbon atoms) with a phenol and an aldehyde. The phenolic chelate resin selectively adsorbs ferric ion and/or cupric ion in an acidic aqueous solution at a pH of 3 and less.

    摘要: A first connection circuit (108) is adjusted to cancel out mutual coupling impedance occurring between a first antenna element (106) in a first frequency band and a second antenna element (107) in a second frequency band, and reduces a degradation occurring due to the coupling between the antenna elements. A second frequency band cutoff circuit (111) for the second frequency band is provided between the first antenna element (106) and the first feeding portion (104).

    摘要: A first antenna element is embodied in a blanched structure, and a second antenna element is embodied in a blanched structure. A low coupling circuit for increasing susceptance with an increase in frequency is interposed between the first antenna element and the second antenna element. The first antenna element and the second antenna element exhibit resonance of a Y12 component of an admittance matrix between first and second frequencies and between second and third frequencies. The first branch element and the third branch element assume a value of nearly a quarter of a resonant electrical length of the Y12 component of the admittance matrix between the first and second frequencies. The second branch element and the fourth branch element assume a value of nearly a quarter of the resonant electrical length of the Y12 component of the admittance matrix between the second and third frequencies.

    摘要: In a folding type portable wireless unit, gain deteriorates sharply upon closure, in the case where an upper case is oscillated directly at the time of opening and used as an antenna in order to attain a wide band and a high gain. The folding type portable wireless unit comprises a first case, a second case, a coupling part for coupling the first and second cases to be opened/closed, a conductor element arranged in the first case, and a power supply element arranged in the second case. In the open state brought by the coupling part, the conductor element and the power supply element approach closely to each other and can be coupled electromagnetically at the time of power supply. In the closed state brought by the coupling part, the conductor element and the power supply element separate from each other as compared with the open state and they are not coupled electromagnetically at the time of power supply.
