Provided is a thermal responsive molecule favorable as a thermal responsive low-molecular hydrogelling agent or the like that gels in response to heat. The thermal responsive molecule is characterized in that an amphiphilic side chain obtained by bonding a hydrophilic side chain such as triethylene glycol and a hydrophobic group such as an octyl group is introduced into a C3-symmetric disc-shaped molecular skeleton such as 1,3,5-benzenetriyltriurea. For example, the thermal responsive molecule is 1,1′,1″-(benzene-1,3,5-triyl)tris{3-(2,5,8,11-tetraoxaheptadecan-17-yl)urea} or the like.

[Problems] To provide a process for producing a transparent electroconductive member, which can produce a transparent electroconductive member having excellent light transparency and electroconductivity at low cost.[Means for Solving Problems] (a) Pattern printing is carried out on a transparent base material using an ink containing a reducing agent to form a reducing agent-containing pattern layer. Next, (b) a metal ion solution containing metal ions, which can function as an electroless plating catalyst upon reduction, is coated on the reducing agent-containing pattern layer, and the metal ion is reduced by contact between the reducing agent and the metal ion to form an electroless plating catalyst layer. Thereafter, (c) an electroconductive metal layer is formed by plating treatment on the electroless plating catalyst layer to produce a transparent electroconductive member.

A scheduling apparatus in a MIMO control station for switching between SU-MIMO mode and MU-MIMO mode receives feedback information from each of a plurality of MIMO terminals. The scheduling apparatus comprises a SU-MIMO selecting unit that selects a terminal that has a SU-MIMO optimal performance metric among all the terminals; a MU-MIMO selecting unit that groups the terminals into at least one set, and selects a set of terminals that have a MU-MIMO optimal performance metric; and a switching unit that compares the SU-MIMO optimal performance metric and the MU-MIMO optimal performance metric to switch between the SU-MIMO mode and the MU-MIMO mode.

A distortion compensation apparatus of the present invention is used in a transmitter that produces and outputs a second signal from a first signal. This apparatus comprises a delay unit for delaying a feedback signal obtained from by the second signal; and a delay control unit for determining a delay quantity of said delay means so that a timing difference between a reference signal obtained from the first signal and the feedback signal delayed by the delay unit is made small. The delay control unit limits the delay quantity within a predetermined limit value.

A photographing lens position control device comprises an image signal capturing unit for capturing an image signal, a focus lens moving unit for moving a focus lens while the image signal capturing unit is capturing an image signal, a retaining unit for retaining a position-dependent image signal, and a photographing lens position determining unit for determining a photographing lens position based on a position-dependent image signal. Since a focus lens is moved while an image signal is being captured as mentioned above, time required for capturing an image signal for determining a photographing lens position is shorter than before.
