摘要:
The control apparatus for controlling a voltage transforming apparatus having a transformer, power switching elements disposed in a primary side, and synchronous-rectifying switching elements disposed in a secondary side includes a judging circuit making a judgment as to whether or not an output current of the voltage transforming apparatus is smaller than a specified current on the basis of a primary-side current of the transformer and an inhibition circuit inhibiting the synchronous-rectifying switching elements from performing their synchronous-rectifying control operation when the judging circuit judges that the output current is smaller than the specified current. The judging circuit makes the judgment on the basis of the primary-side current flowing through the primary coil of the transformer immediately before the power switching elements are turned off.
摘要:
A driving circuit has a p-channel transistor and an n-channel transistor. A power switching element is set at an on state each time the p-channel transistor sets a charging line at a conductive state in response to a leading edge of an output pulse to supply a positive charge to a gate of the element through the charging line. The element is set at an off state each time the n-channel transistor sets a discharging line at a conductive state in response to a trailing edge of the output pulse to discharge the supplied charge through the discharging line. A through current occasionally flows through the transistors set at the on state together. The driving circuit has resistors between the transistors to suppress the through current.

In a DC to DC converter, a transformer circuit includes a primary winding and a secondary winding member composed of series-connected first to fourth secondary windings having one and the other ends. The one and the other ends of the series-connected first to fourth secondary windings are connected to a first output terminal. The first and second secondary windings are wound around a first magnetic path in opposite directions, and the third and fourth secondary windings are wound around a second magnetic path in opposite directions. A first rectifying element is connected between the second output terminal and a connection point between the first and second secondary windings. A second rectifying element is connected between the second output terminal and a connection point between the third and fourth secondary windings.

A silencer for a motorcycle has a front cup which has a tapered tubular shape, a center sleeve which is connected to the front cup, and a tail cup which is connected to the center sleeve. Since the front cup has a tapered tubular shape, the front cup is arranged such that a front end of the front cup is positioned in the vicinity of a main frame. A distal end of the silencer can be shifted frontward in the longitudinal direction of a vehicle compared to a silencer of a prior art. As a result, a length of the silencer can be increased while avoiding interference between the silencer and legs of a rider and hence, silencing performance of the silencer can be enhanced. Since the distal end of the silencer can be shifted frontward in the longitudinal direction of the vehicle, the concentration of a mass can be acquired.

The present invention is regarding plants and plant storage organs thereof in which GLP-1 derivatives are accumulated, and methods of producing them. The transgenic plants and plant storage organs thereof accumulate tandem repeated GLP-1 derivatives cleavable with intestinal digestive enzyme to monomeric molecules and are produced by methods comprising: integrating into vectors linked DNAs which comprise tandem repeated DNAs encoding the GLP-1 derivative with trypsin resistance in which the amino acid in the 26th position is Gln, the amino acid in the 34th position is Asn or Asp, and C-terminal consists of Arg or Lys to produce monomeric molecules; introducing the vectors into plant cells; and redifferentiating the obtained transformants. The edible transgenic plants and plant storage organs are useful for treating diabetes and can be ingested by diabetic patients.
