Title: Interdigital capacitor
Inventor: IKEDA YUKIO
IPC: H01P5/04
Filed: 1982-12-09
Abstract: PURPOSE:To vary characteristic impedance and a wavelength shortening rate in the case when the capacitor is regarded as a distribution fixed-number line by forming an epitaxial layer to the lower section of opposite fingers, joining a Schottky with a boundary surface between one finger and the epitaxial layer and forming an ohmic junction to the other finger. CONSTITUTION:The epitaxial layer 13 formed to the lower section of the opposite fingers 4, 5 of the interdigital capacitor used for a microwave integrated circuit, and the Schottky junction surfaces are formed to the boundary surfaces 15 among one fingers 4 and the epitaxial layer 13 and the ohmic junctions to boundary surfaces 16 among the other fingers 5 and the epitaxial layer 13. Consequently, the size of an extent of a depletion layer 18 changes by adjusting a bias power supply 17, and the magnitude C3 of an equivalent variable capacitance 19 depends upon the size of the extent of the depletion layer 18 because the equivalent variable capacitance 19 consists of the coupling capacitance of the fingers 4 and the fingers 5 and depletion capacitance depending upon the extent of the depletion layer. Accordingly, characteristic impedance and the wavelength shortening rate in the case when the interdigital capacitor is regarded as the distribution fixed-number line can be changed by adjusting the bias power supply 17 and altering C3.

Title: Resin molded coil
Inventor: KUBO HIROBUMI
IPC: H01F27/32
Filed: 1983-11-18
Abstract: PURPOSE:To obtain a resin molded coil having superior corona characteristics, allowing miniaturization and light weight thereof, and of a low cost by composing continuous reinforced resin layers having a fixed dielectric strength at the snrface of a primary resin molded coil which is opposed to a secondary coil and in the inside of which gaseous phase is formed using a separate body. CONSTITUTION:A primary coil 11 which is taken off from a mold after being hardened and on the inner periphery of which a reinforced resin layer 10 having the thickness of (l) is formed for its completion is concentrically disposed on the external side of a secondary coil 2. Incidentally, the both coils are disposed so as to keep an interval L2 between them via a spacer 12. If a high test voltage is applied between the primary coil 11 and the secondary coil 2, this test voltage is induced between opposed resins of the both coils. If this induced voltage is sufficiently high, discharge in the air yields at intervals by the distance L2 between the both coils. However, insulation breakdown of the coil 11 is prevented, because the reinforced resin layer 10 is present. Accordingly, even if an impulse voltage such as a lightening and so forth invades and discharge yields between the primary and secondary coils, insulation breakdown of the primary coil is prevented.
