A modular television apparatus including a video display module, a tuner module, and a power supply module, the modules being releasably combinable in a variety of combinations. The tuner module is provided with a switch for controlling a supply of power supply voltage from the power supply module to the remaining modules. The tuner module has a casing including an elongated recess into which a telescopic antenna can be stored, the recess conforming to the shape of the antenna. Switches are disposed within the recess, some of the switches having an exposed surface that conforms to the contour of the recess. The video display module is provided with a circuit for controlling the supply of power to other circuits according to detection of input of audio/video signals to the display modules.

Even after power-down, distinction between a transition from a PLL normal-oscillation state and a transition from a PLL self-oscillation is allowed.A semiconductor device includes a first region which, after having transited from a power-supply state to a power-down state, returns to the power-supply state again, a second region which holds a power source voltage regardless of power-down of the first region, and an oscillator which generates a first clock signal supplied to the first region. The first region includes a PLL circuit. The second region includes an information holding unit capable of holding information which can distinguish whether the operation mode of the PLL circuit is a PLL normal-oscillation mode or a PLL self-oscillation mode, and determines the operation mode of the PLL circuit when the first region has returned from the power-down state to the power-supply state, according to the information held in the information holding unit.

[Problem] To provide a method that efficiently produces antigen-specific monoclonal antibodies from a wide range of animal species, and to provide a new antigen-specific monoclonal antibody using this technique. [Solution] A nonhuman animal is immunized with a target antigen, lymph fluid or the like is collected from the immunized nonhuman animal, or lymph fluid or the like is collected from a human having antibodies to the target antigen, the collected lymph fluid or the like is combined with (1) a labeled target antigen and (2) a marker that can selectively binds to plasma cells and/or plasmablasts, and cells that have bound to (1) the labeled target antigen and (2) the marker are then selected. The plasma cells and or the plasmablasts that have specifically bound to the target antigen by the method are selected, an gene of an antibody for the target antigen is collected from the selected cells, the base sequence thereof is identified, an antibody or antibody fragment is prepared on the basis of the base sequence of the identified gene, and an antibody or antibody fragment specific to the target antigen is produced.

Provided is a method for selectively obtaining, for a given target gene, a “joined DNA fragment” wherein just a target gene fragment is joined with desired other DNA fragments, regardless of whether a DNA fragment containing a target gene sequence has been purified. In the provided method, a double-stranded joining DNA fragment containing a sequence A and/or a sequence B is selectively joined to the ends of a target gene fragment. A mixture of a double-stranded gene fragment, the 3′ end of which is protruding, and the double-stranded joining DNA fragment, which are related in a prescribed manner, undergoes at least two cycles of thermal denaturation, reassociation, and DNA synthesis, resulting in a “joined DNA fragment,” which is a double-stranded DNA fragment including at least one instance of a sequence resulting from joining sequence A, the target gene sequence, and sequence B. A “single-side joined DNA fragment” can also be obtained, by a similar method.

The present invention is directed to a stereo/monaural selecting circuit having a jack for supplying therefrom for reproduction a stereophonic sound signal output or a monaural sound signal output to apparatus connected thereto, or for receiving for recording a stereophonic sound signal input or a monaural sound signal input from apparatus connected thereto. The jack can be used with either a binaural plug or a monaural plug inserted thereinto, which are attached to stereophonic apparatus or monaural apparatus, respectively, and the circuit selects automatically either a stereophonic operating state or a monaural operating state in response to the type of plug inserted into the jack. In the case where the circuit contains a speaker, the circuit supplies the monaural sound signal output to the speaker when no plug is inserted into the jack.
