Title: Adaptive antenna and method for controlling antenna directivity
Inventor: HIRATA KAZUFUMI
IPC: H01Q3/26
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To extract desired wave components with high accuracy by minimizing average power of a measured difference signal through an updated weight coefficient and giving an instruction of fixing the weight coefficient to a coefficient immediately prior to detection of the arrival of a desired signal, when detecting the arrival of the desired signal from the measured difference signal so as to suppress interference components. SOLUTION: A weight coefficient computer 15 uses output signals from IQ signal converters 14-i(1, m)-14-i(I, m) (m=1 to M) and an output signal from an IQ signal converter 14-0 to compute weight coefficients w1,1-M to wI, 1-m (m=1 to M) that are used to minimize average power of difference signals e1(n)-eM(n) outputted from subtractors 17-1 to 17-M. when a signal detector 19 detects a signal sequence from a mobile set, the detector 19 gives an instruction for fixing the weight coefficients to the weight coefficients w1,1-M to wI,1-m (m=1 to M) immediately prior detecting the signal sequence to a weight update controller 18, which stops updating the weight coefficients.

Title: Position follow-up controlling system of magnetic head
Inventor: SUGAYA JIYUKOU
IPC: G11B5/596
Filed: 1983-09-29
Abstract: PURPOSE:To prevent a tracking state from being shifted due to a medium defect and an external noise, in the course of a position follow-up control, by using a conventional position follow-up control system in a settling period, and limiting a current flowing to an actuator to 1/several of the settling period, in an on- track period. CONSTITUTION:The maximum value of a current flowing to an actuator is limited in an on-track period except a settling period by a position follow-up control, by adding a current limiting circuit 23 or a position signal compensating circuit 21 to an output 15-1. According to such a constitution, even if a large position variation such as an H point occurs, since a driving current is limited, a position variation generated thereafter is small as a result, and the position is not shifted from on-tranck.

IPC: H04N9/83
Filed: 1981-11-09
Abstract: PURPOSE:To prevent deterioration in the picture quality of a reproduced color signal due to a decrease in color output level and an increase in mixed disturbing wave due to high-density recording, by emphasizing and recording the side band wave of a low frequency converted color signal and suppressing the side band wave on a reproduction side. CONSTITUTION:A luminance signal component in an input video signal 1 is separated through an LPF2 and a modulate by an FM modulator 3. Color components are separated by a BPF4 and converted to low frequency through a balanced modulator 5, oscillator 6, and LPF7. The low-frequency converted color signal has its color signal side- band wave emphasized by a side-band emphasizing circuit 8 and is mixed by a mixer 9 with the FM signal and the output signal of an auto tracking pilot signal generator 12. A three-frequency mixed signal reproduced by a reproducing head 11, on the other hand, is mixed by a head amplifier 13, and said emphasized component emphasized during recording is suppressed by a side-band suppressing circuit 16 to separate the reproduced color signal into a low frequency color signal through an LPF17. Consequently, the influence of a disturbing wave signal generated between the circuit 8 and circuit 16 is reduced without deteriorating the color picture quality.

Next, a photosensitive layer 56 of the photosensitive drum 1, and the screen drum 17 are electrified, for instance, to positive and negative, respectively. In this state, when a positive ion particle is projected from a charged particle source 19 of the screen drum 17, it passes through the drum 17, reaches the photosensitive layer 56 as positive image information, and a latent image is synthesized newly. Accordingly, the latent image separated into a chromatic color level of the first group of positive and a chromatic color level of the second group of positive is formed on both sides of an achromatic color potential level, therefore, a distinct image can be obtained.

Title: Liquid growth method
Inventor: YAGI TETSUYA
IPC: H01L21/208
Filed: 1988-07-18
Abstract: PURPOSE:To perform an epitaxial growth on an AlGaAs wafer by performing the epitaxial growth using mixture gas of hydrogen and arsine as an atmospheric gas. CONSTITUTION:Atmospheric gas 8 is composed of hydrogen and arsine. The arsine generates radical hydrogen thermally decomposed at a high temperature section, i.e., a place where a graphite boat 4 is mounted in an LPE furnace or bond of radical hydrogen and arsenic. The radical hydrogen or the bond of hydrogen and arsenic removes by reducing an oxide film on a substrate 1 to be grown, and the surface of the substrate 1 is always held in a clean state. Thus, even when an AlGaAs wafer having large Al molar ratio such as 0.45 which is once exposed with the atmosphere is used as the substrate 1 to be grown, the oxide film on the surface oxidized in the atmosphere is removed by reducing in the furnace. Accordingly, a material melt 3 is sufficiently brought into contact with the surface of the substrate 1 grown with the AlGaAs, and a uniform epitaxial layer of high quality is grown.
