Abstract: A device for capturing insects can include a handle and a head fastened to one end of the handle. The head can include a holder intended to contain a pack of adhesive sheets suitable for holding an insect and a frame that matches the holder and has at least one rim intended to cover part of the pack of adhesive sheets. The rim can be configured so as to constitute a predetermined tear-away zone on the pack of adhesive sheets, so that each adhesive sheet from the pack of adhesive sheets can be peeled apart from each other without multiple sheets being removed together. The frame can define a cavity adjacent to one adhesive face of the pack of adhesive sheets so that insects present in the cavity adhere to the adhesive sheet.

Abstract: This device for capturing insects comprises: a handle (10), a head (11) fastened to one end of the handle (10). The head (11) comprises: a holder intended to contain a pack of adhesive sheets (13) suitable for holding an insect, and a frame (14) that matches the holder and has at least one rim (15) intended to cover part of the pack of adhesive sheets. The rim (15) is configured so as to constitute a predetermined tear-away zone (Z1) on the pack of adhesive sheets (13), so that the adhesive sheets can be peeled apart from each other without multiple sheets being removed together. The frame (14) defines a cavity (16) adjacent to one adhesive face (17) of the pack of 20 adhesive sheets (13) so that insects present in the cavity (16) adhere to the adhesive sheet.

Abstract: The invention relates to a semiconductor device including an amplifier, and a mobile telecommunication terminal comprising this semiconductor device. The amplifier has a very high frequency a.c. signal and comprises a last stage but one of depletion-layer MESFET transistors (T3) and a last transistor stage (T4) of the same type, coupled by a d.c. isolation capacitor (C4). This capacitor (C4) forms with the intrinsic diode (.increment.4) of the transistor (T4) of the last stage a series-arranged rectifier circuit. The latter imposes a shift of the mean level of the a.c. signal on the terminals of said isolation capacitor once the amplitude of the positive part of this a.c. signal has exceeded the conduction threshold of the intrinsic diode (.increment.4). This shift of the mean level (-1.5 volts) is used as a negative voltage (-VG) for biasing the coupled gates of all the stages of the amplifier circuit.
