A flying insect trapping device configured to be used with a fuel supply containing combustible fuel. The device may include a supporting frame; an insect trap chamber carried on the supporting frame; and a combustion device which may also be carried on the supporting frame. The combustion device comprises an inlet port for connection with the fuel supply, an exhaust port, and a combustion chamber communicating the inlet port with the exhaust port. The inlet port enables the fuel from the fuel supply to flow into the combustion chamber for continuous combustion therein to create an exhaust gas within the combustion chamber. The combustion device further includes a catalyst element disposed within the combustion chamber. The catalyst element has a catalyst body with a plurality of essentially linear elongated conduits for enabling the exhaust gas created in the combustion chamber to flow therethrough towards the exhaust port. The catalyst body includes a catalytically active material that, during operation, converts carbon monoxide in the exhaust gas to carbon dioxide as the exhaust gas flows through the elongated conduits. An insect inlet is communicated with the insect trap chamber to enable flying insects to enter the trap chamber through the insect inlet. A vacuum device communicated to the insect inlet is constructed and arranged to draw insects attracted to the exhaust outlet through the insect inlet and into the insect trap chamber.

There is provided a pipette device capable of adjusting a collection amount in a short time. A pipette device 1 adjusting a volume of a cylinder portion 'a' by the axial-direction movement of a plunger 3 caused by the rotation of a push rod 5 includes a speed increasing mechanism 35 provided between a pipette main body 2 and the push rod 5 and increasing a speed of input rotation to transmit the input rotation with the increased speed to the push rod 5.

A coil device is provided with a coil and a holder which holds the coil. The coil is formed by a conductive wire being wound in a wound wire direction and includes a plurality of turns that are adjacent in a direction intersecting the wound wire direction. The holder includes a plurality of first holding portions that hold the conductive wire in such a way that the conductive wire passes along a plurality of first paths corresponding to the plurality of turns, and at least one second holding portion which holds the conductive wire in such a way that the conductive wire passes along a second path extending in a direction intersecting the wound wire direction and connecting the first paths.

As to the connector having a floating structure in which a movable substrate coupled with the connector is integrally fitted to a housing of the connector, a contacting part of the connector with another is made faced with a connector-setting window of a cradle housing, and the connector is structured to move freely within the range of the gap, an elastic part made of the same member as either a fixed cradle housing or the connector is formed between a fixed cradle housing side and a freely moving connector side to return the connector to an original position by returning force of the elastic member when the connector is released from linking with the other.

A bipolar transistor and a radio frequency amplifier circuit capable of preventing thermal runaway in the bipolar transistor without affecting the radio frequency amplifier circuit, which includes: a direct-current (DC) bias terminal to which a DC bias is supplied; a DC base electrode connected to the DC terminal; a radio frequency (RF) power terminal to which a radio frequency signal is supplied; an RF base electrode connected to the RF terminal; and a base layer connected to the DC base electrode and the RF base electrode.
