Title: Adaptive control filter including pole and zero point
Inventor: FUKAZAWA ATSUSHI
IPC: H03H17/06
Filed: 1983-01-17
Abstract: PURPOSE:To improve the stability and to minimize the transition of phase by monitoring whether the root of a Chebyshev's polynomial satisfies a separation law. CONSTITUTION:For characteristics of nonrecursive filters 19 and 20 obtained when attention is paid to terminals 14 and 15, both the zero point and pole are obtained at a time with each transmission function (a zero filter 19 and a pole filter 20 respectively). While filters 19-22 have an equal constitution, and the differences exist only with the order number, the tap coefficient and the definite value of root. It is found that all roots are imaginary when the transmission function (h) is examined with estimation filters 19-22, and these imaginary roots exist on a unit circle. In this case, the monitor is given to check the phase of each root and whether the roots are different from each other. That is, the separation law is monitored. The system stability is secured with examination of the separation law. It is easy to obtain the stable working also with a sequential adaptive estimation filter whose response characteristics are sequentially controlled.

Title: Dry etching device
Inventor: GOTO YOSHIMI
IPC: C23F4/00
Filed: 1989-01-11
Abstract: PURPOSE:To enable dry etching treatment in which the damage of an etching resist is small and which is excellent in vertical etching property by putting a holder, which has plural openings that are distributed uniformly, between a sample to be etched and an opposite electrode. CONSTITUTION:In a holder 18, a plurality of openings 18a are distributed uniformly at an Al plate, for example, 1mm thick, and the holder is installed specified distance apart from the surface of the sample to be etched with feed 18b placed on a plane electrode. By installing this holder 18, some of active ions 17, which enter in the direction of a planar electrode by electric field acceleration from a plasma of reaction gas that is generated below an opposite electrode 14, are shielded. Since only the active ions which passed the opening 18a do sputter etching actions, the damage of a resist decreases. Even if the energy of ions are enlarged by lowering the pressure of the reaction gas this way, only a part of ions which have passed the opening of the holder collide against the resist and the face to be etched, so the damage of the resist decreases. Also, since the etching speed of a substance to be etched such as chromic film, etc., does not lower much, vertical etching excellent in selection ratio can be done.

Title: Magnetic bubble memory element
Inventor: OHASHI MAKOTO
IPC: G11C11/14
Filed: 1986-01-16
Abstract: PURPOSE:To repulse bubbles due to distortion produced by the internal stress of a metallic film and to prevent the jump of the bubbles to adjacent transfer lines by covering the outer circumference of a bubble transfer line with a metallic thin film pattern. CONSTITUTION:A metallic thin film pattern 6 is formed with a position distant away by slight width W defined as a boundary 7 as if the pattern covered a bubble transfer line formed by ion implantation. The pattern 6 uses an elec tronic beam vapor deposition film of Mo/Au/Mo whose internal stress is equal to the tension stress. While the width W is set within 1/2 minimum distance together with (the bubble radius) <W< (distance between adjacent transfer lines) satisfied respectively. In such constitution, the potential is produced for repulsion of bubbles at a point near the boundary 7 by the internal stress of the thin film 6. This potential serves as a guard rail to prevent the jump of bubbles to other transfer lines.

Title: Focus controller for optical head device
Inventor: TANAKA HIDEKI
IPC: G02B7/28
Filed: 1987-01-14
Abstract: PURPOSE:To improve the focus gains by using the focus control signal obtained from a photodetector through a limiter amplifier circuit. CONSTITUTION:A limiter amplifier circuit 10 is obtained by adding a limiter to the output S-AF of a differential amplifier 1 in addition to a conventional constitution. The output of the circuit 10 is used as the input signal of a phase compensating circuit 2. In other words, the focus control signal obtained from a photodetector is used through the circuit 10. Thus the focus gains can be increased by the amplifying function of the circuit 10 against a focus shift of about + or -1mum caused at a position near the focus point. In addition, a limiter which functions to keep the output within a fixed level can avoid such cases where the peak-to-peak voltage level exceeds the capacity of a servo system within a pull-in range in a pull-in state and the servo system is unstable. As a result, the satisfactory focus gains can be obtained at a position near the focus point and the signals are obtained within the capacity of a control circuit in a pull-in state.
