Abstract: A method of producing a surface-mount inductor by encapsulating a coil with an encapsulation material containing a resin and a filler using a mold die assembly is provided. In the method, a tablet and a coil are used. The tablet is prepared by preforming the encapsulation material into a shape having a flat plate-shaped portion and a pillar-shaped convex portion on a peripheral thereof. The coil is a wound conductive wire having a cross-section of rectangular-shape. The coil is placed on the tablet to allow both ends of the coil to extend along an outer side surface of the pillar-shaped convex portion of the tablet. The coil and the encapsulation material are integrated together while clamping the both ends of the coil between an inner wall surface of the mold die assembly and the outer side surface of the pillar-shaped convex portion of the tablet, to form a molded body. External electrodes are formed on a surface of or around an outer periphery of the molded body in such a manner that the external electrodes are electrically connected to the both ends of the coil at least a portion of which is exposed to the surface of the molded body.

In order to vary the output current, the constant current source circuit includes a switching circuit 5 (transistor M5) connected in series to a series circuit connecting in series the transistor M1 and the resistor RS, and a second constant current circuit 4 connected in parallel to a series circuit connecting in series the transistor M1, the resistor RS and the transistor M5.

Abstract: Disclosed is an input/output coupling structure for a dielectric waveguide resonator to be mounted on a printed circuit board, which comprises; a region defined in the printed circuit board and surrounded by a first conductive film formed on the front surface of the printed circuit board and connected to a microstrip line on the printed circuit board, a second conductive film formed on the back surface of the printed circuit board, and a conductive wall connecting the respective peripheries of the first and second conductive films; a first slot formed in the front surface of the region; and a second slot formed in a surface of the dielectric waveguide resonator which is disposed to be opposed to the region of the printed circuit board. The first and second slots are adapted to be disposed in opposed relation to one another. The coupling structure can achieve the connection between a dielectric waveguide resonator and a microstrip line without forming any input/output electrode on the resonator, to facilitate the application of the dielectric waveguide resonator to an electronic circuit even if it is intended to be used in millimetric-wave band.

Abstract: Disclosed is a constant voltage power supply, which comprises an error amplifier VEA including a transistor M3, and a transistor M4 having the same ratio between channel width and channel length as that of the transistor M3. The gate and source of the transistor M4 are connected to the gate of a transistor M3 to form a current mirror circuit in conjunction with the transistor M3. Further, the drain of the transistor M4 is connected with a transistor M5 adapted to be switched in response to an external control signal Sg. For example, when the transistor M5 is in ON state, any signal amplification function of the transistor M3 is vanished away, and the gain of the error amplifier VEA is lowered. The circuit configuration for changing the gain of the error amplifier VEA makes it possible to strike a balance between high-speed response characteristic in an active mode and operational stability in a sleep mode, and reduce a circuit area required for being formed on an integrated circuit.
