Patent JP-S619004-A (JP)
Title: Double balanced modulator
Inventor: IGATA YUUJI
IPC: H03C1/54
Filed: 1984-06-22
Abstract: PURPOSE:To eliminate leakage of an input signal in excellent way with simple constitution by synthesizing the input signal and an output signal in applying AM modulation and AM demodulation so as to eliminate the leakage of the input signal from the output signal. CONSTITUTION:An input modulation signal inputted to a modulation signal input terminal 6 is fed to a double balanced modulation circuit 5 and also to a synthesis level adjusting section 15. The amplitude of a modulation signal is adjusted by using a variable resistor VR1 in the synthesis level adjusting section 15 and the signal is outputted with a high output impedance. When the leakage of the modulation signal to the output of the modulation circuit 5 is in phase to the input modulation signal, a changeover switch SW1 is thrown to the position of a terminal (a) and when opposite phase, the changeover switch SW1 is thrown to the position of terminal (b), then the leaked modulation signal is suppressed and does not appear at an output terminal 14. Since the synthesized level adjusting section 16 is entirely the same circuit constitution as the synthesis level adjusting section 15 and an input carrier signal is applied from a carrier signal input terminal 7, then the level of the carrier signal is adjusted by a variable resistor VR2 so as to eliminate the leakage of the input carrier signal at the output of the modulation circuit.

IPC: H04J13/10
Filed: 1995-04-28
Abstract: PURPOSE: To output frequency information being a random spreading code from a frequency table in a radio transmitter using frequency hopping as a spread spectrum modulation system. CONSTITUTION: This spreading code generator is provided with an M-sequence code generator 2 for generating an M-sequence false noise code in each frequency hopping period based upon a clock generated from a frequency hopping clock generator 1 and a noise code generating part 6 for amplifying a heat noise by an amplifier 3 and binarizing the amplified signal through an A/D converter 5 based upon a clock generated from a sampling clock generator 4 to generate a noise code. A frequency table 8 is prepared by rearranging frequency information in a frequency table (original table) 7 in which a series of frequency information is registered by using each noise code as an address. Thus frequency information (spreading code) being a random spreading code is outputted from the table 8 by using an M-sequency false noise code as an address.

Title: Field emission cold cathode
Inventor: MATSUZAKI TADAHIRO
IPC: H01J1/30
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce a leakage current caused in an insulating layer side wall between a gate electrode and a cathode base board without impairing mechanical strength of an element by arranging emitter electrodes in a cavity formed between a columnar insulating layer and a gate layer, and forming pares reaching the columnar insulating layer in an outer peripheral part of an emitter electrode forming area. SOLUTION: A side wall 7 becoming a leak path is eliminated by removing a part except for a place to support a gate electrode 4 among an insulating layer 3 existing between the gate electrode 4 and a cathode base board 1. Therefore, the side wall area is reduced, and a leakage current is reduced, and since the insulating layer is removed, parasitic capacity is also reduced. In an emitter area outer peripheral part, since an insulating layer side wall is kept away from emitter electrodes 2a and 2b, density in which the emitter electrodes scattered by sputtering at operation time stick to the side wall, can be reduced, and the leakage current is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent molding defect such as bubble marks and weld from being generated on the outer surface of an upper or lower cassette half by arranging a gate connection part where a gate is connected at the time of molding near a part where a reel-positioning rib is provided on a flat plate.
