Title: Cathode ray tube display device
Inventor: KANAI TOSHIO
IPC: H04N9/29
Filed: 1989-06-26
Abstract: PURPOSE:To attain purity correction by providing a changeover switch causing a DC current to flow to a coil wound in 8-shape on a funnel to which AC current normally flows. CONSTITUTION:A power switch 6 is applied and degaussing of a shadow mask is finished, changeover switches 15, 16 are thrown to cause a DC current to flow to a 2nd coil 4. Since the coil 4 is wound in 8-shape, suppose that a current flows from the upper to the lower direction at the left side of a CRT, the current flows also from the upper to the lower direction at the right side of the CRT. On the other hand, suppose that the current of the 1st coil 3 flows from the upper to the lower direction at the left side of the CRT, the current flows from the lower to the upper direction at the right side of the CRT. Thus, the magnetic field formed by the two coils 3, 4 is added at the left side of the CRT and cancelled at the right side. Thus, purity adjustment is applied individually at the left and right side of the CRT by adjusting variable resistors 13, 18.

Consequently, gas pressure of a gas cell Rg and hydraulic pressure in the cylinder are balanced, and a piston 3 moves to slide in the expansion side direction. Consequently, projection of the piston rod 2 is carried out by energizing force of the suspension spring S and the gas pressure of the gas cell Rg, and it is possible to reduce weight of a damper and cost without raising the gas pressure comparatively high.

Title: Band variable band pass filter
Inventor: NOBORI MITSUHIRO
IPC: H03H7/12
Filed: 1984-08-06
Abstract: PURPOSE:To suppress the fluctuation of insertion loss even if the Q of a resonance circuit is varied by adding a pin diode to the resonance circuit comprising L, C and the pin diode and controlling externally both the pin diodes. CONSTITUTION:When a voltage Vc at a conctol terminal A is zero, a maximum current flows to the pin diode D1 and no current flows to the pin diode D2. In this case, the circuit Q is maximized. Although the current flowing to the diode D1 is decreased gradually in increasing the Vc, the Q is not changed largely by the characteristic of the pin diode. In increasing the Vc further, the Q is decreased and when the loss is increased, a current flows to the diode D2 via a Zener diode D3 to compensate the loss. Thus, even if the Q of the resonance circuit is changed, the fluctuation of the insertion loss is suppressed.

Title: Laminated dielectric filter and its production
Inventor: TSUGAI TOMOHIKO
IPC: H01P1/203
Filed: 1995-06-07
Abstract: PURPOSE: To provide a compact laminated dielectric filter against a small pass band width by reducing the spaces set among the conductors in a resonator after placing a linear coupling control conductor among the resonator conductors in a dielectric chip to control the degree of coupling between adjacent resonators and connecting the end part of the control conductor reaching its outer surface to an external ground conductor. CONSTITUTION: The linear coupling control conductors 18 which control the degree of coupling between adjacent resonators are placed between the internal resonator conductors 12a and 12b and also between 12b and 12c respectively and almost in parallel to these conductors 12a to 12c. Then both end parts of every conductor 18 reaching its outer surface are connected to every outer surface ground conductor 14. An extremely small pattern width suffices for every conductor 18, and, for example, both conductors 18 can be formed on the same layer as the conductors 12a to 12c. Thus the degree of coupling can be reduced among conductors 12a to 12c, so that the pass band width can be reduced for the filter characteristic.
