Title: Coupling circuit
Inventor: UMEMURA YOSHIHARU
IPC: H04B1/26
Filed: 1989-09-04
Abstract: PURPOSE:To prevent heat interference from being generated in the circuit of a rear step by inserting a trap circuit between the intermediate frequency output end of a tuner and the circuit of the rear step and suppressing the leaked component of a video carrier or a local oscillation frequency. CONSTITUTION:A rear step circuit 2 is composed of an intermediate frequency amplifier or a surface wave filter, etc. Between an intermediate frequency output end 3 of a tuner 1 and the rear step circuit 3, a trap circuit 4 is inserted to be tuned to a video carrier frequency almost double to the video intermediate frequency. Otherwise, a trap circuit 5 is inserted to the local oscillation frequency to be almost three-times of the video intermediate frequency. Otherwise, by inserting these two kinds of the trap circuits 4 and 5, the video carrier or local oscillation frequency component to be leaked from the output end 3 is suppressed and the beat interference to be generated in the rear step circuit 2 can be prevented.

IPC: H03H9/10
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To see that an electronic part is easy of mass production and is low- cost, and that load is hard to fall on an element and the element can be sealed completely, by sealing it with a cap in condition that the element is mounted on a board without using case having an aperture. SOLUTION: A metallic cap 20 to cover an element 10 is bonded onto a substrate 1 to seal the element 10. An insulating cap such as alumina ceramics, resin, or the like may be used as the cap 20. The aperture of the cap 20 sticks fast onto the insulating layer 5 of the board 1 by applying an adhesive for sealing in advance to the aperture of the cap 20 into uniform thickness by transcription or the like, and putting on the cap 20 on the board 1 where the element 10 is mounted. Heating it in this condition will harden the adhesive for sealing and complete the bonding and sealing of the cap 20 to the board 1. After connection of lead terminals 30-32, the periphery of the board 1 and the cap 20 is dip-coated with insulating top-coat resin 40.

Title: Liquid crystal display device
Inventor: KABUTO NOBUAKI
IPC: G02F1/133
Filed: 1988-09-14
Abstract: PURPOSE:To realize the subject device which does not generate the inclination of luminance in the vertical direction of a liquid crystal cell by impressing two voltages which are changed in synchronism with period of alternating the voltage of counter common electrodes, to the off potential of a row scanning electrode, in stead of being connected an additional capacity to the liquid crystal cell in parallel. CONSTITUTION:The impressed voltage of the off potential of the row scanning electrode G is changed with the same timing to that of the counter common electrode C simultaneously changing the voltage of driving electrode S of each picture elements through the capacity of the liquid crystal cell at the time of changing the voltage of the counter common electrodes C. Namely, the voltage V1 of turning a picture element transistor M to on at the time of selectively changing-over the voltage, is converted to the voltage V2 or V3 (V2>V3) of turning the picture element transistor M to off in synchronism with the changeover timing of the voltage applied to the counter common electrode C at the time of non-selectively changing-over the voltage. Thus, even if the additional capacity is not connected to the liquid crystal cell in parallel, as the inclination of luminance in the vertical direction of the liquid crystal cell is not generated, the clear device which has improved production yield and is reduced cost, is obtd.
