Abstract: The present invention provides a dielectric waveguide resonator comprising a pair of rectangular parallelepiped-shaped dielectric blocks being in contact with each other through respective contact surfaces thereof. The dielectric waveguide resonator has an outer periphery coated with an electrically conductive film except for the contact surfaces, and is configured to resonate in a TE mode. A probe composed of an electrically conductive film is formed on at least one of the contact surface. Thus, it becomes possible to provide a dielectric waveguide resonator having a simple structure, requiring no adjustment structure, and comprising a structure for conversion between a dielectric waveguide and a coaxial line.

Abstract: Dielectric waveguide comprising dielectric body having an exterior coated with an electrically conductive film. Region in one side surface couples to another dielectric waveguide, and slot in bottom surface exposes the dielectric body in an L-shape in two adjacent side surfaces, except for the one side surface. Front surface of printed circuit board has a ground pattern opposed to the slot, which includes opening with outer shape greater than slot, and a back surface having a ground pattern surrounding a strip line disposed to cross through the slot. A distal end of the strip line and the front surface-side ground pattern are coupled together by a via hole. The opening is surrounded by a via hole group which couples the front and the back surface-side ground patterns together. The dielectric waveguide is disposed to allow the opening and the slot to be opposed to each other.

The feedback circuit 7 is operable to supply the first feedback signal to the control circuit 4 in a current supply period, and to supply the second feedback signal to the control circuit 4 in a current cutoff period. The second feedback signal has a signal value approximately equal to that of the first feedback signal appearing in the current supply period. The switching constant-current power supply system can stabilize the load current even under the condition that the load is repeatedly turned on/off.

Abstract: A delay line device comprising a first group of coils arranged in a first straight row, and a second group of coils arranged in a second straight row which is parallel to the first row. The second group of coils are generally deviated toward the input side of the delay line with respect to the first group of coils. Electrical connection is provided between the successive coils in the first and second groups. An input is imparted to the first one of the coils in the first group as viewed from the input side, and an output is taken from the last one of the coils in the second group also as viewed from the input side. The axial direction of each of the coils in the first and second groups is so selected that the couplings between the most adjacent ones of the coils in the first and second groups are positive and that the couplings between the coils in each of the groups are negative. Furthermore, each of the coils in the first and second groups is provided with a tap, which is grounded through a capacitor.
