Title: Gain adjuster for tracking control system
Inventor: WATANABE KATSUYA
IPC: G11B7/085
Filed: 1990-05-11
Abstract: PURPOSE:To shorten the gain adjusting time of a tracking control system by calculating the real number part of a transmission function of the control system based on an answer signal and a disturbance signal of the control system against the disturbance signal and switching the loop gain so as to set the calculated real number part at about 0. CONSTITUTION:A microcomputer 24' contains a disturbance application means 24'a and applies a disturbance signal of a frequency fA to a tracking control system from a port A via a synthesizing circuit 18 so that the phase difference is set at about -90 deg. between the disturbance signal and an answer signal when the optimum loop gain is secured in the control system. The answer signal of the tracking control system is sampled and measured by an A/D converter 22 against the disturbance signal. Based on these disturbance and answer signals, the real number part of a transmission function is calculated in the control system. Then the switch groups 25a of a gain switch circuit 25 are switched so that the calculated real number part is set at about 0. Then the prescribed resistance value is selected for switch of the loop gain. Thus the gain of the tracking control system can be quickly adjusted.

Title: Semiconductor device and wiring design therefor
Inventor: NAKAMURA TAKESHI
IPC: H01L21/82
Filed: 1993-05-25
Abstract: PURPOSE:To realize a high density semiconductor device by disposing the cells for leading out the wiring only on the side of wiring channel region contiguous to the logic cell region. CONSTITUTION:Adjacent logic cells are subjected to comparison of the edge types 9a, 9b thereof. If they are different, the edge type 9a on the left of a logic cell 3a is alpha type and the edge type 9b on the right of a logic cell 3x is beta type having no terminal and thereby a cell 10 for leading out the wiring is generated. Interconnection information 11 of a terminal 12 and the adjacent terminals 7a, 7b, 7c on the edge of the logic cell 3a is generated in the wiring lead out cell 19. The X coordinate of terminal 12 is shifted for each wiring grid while the Y coordinates, corresponding in number to the terminals, are arranged at same coordinates as the adjacent terminals 7a, 7b, 7c thus conducting an embedded placement design between the logic cells 3a and 3x. Subsequently, automatic routing is conducted. Since the cells can be placed without shifting, the overall area is reduced resulting in high density.

Filed: 1989-05-15
Abstract: PURPOSE:To make the circuit stable by forming a constant current generating circuit with a series circuit comprising a field effect transistor(TR) and a resistor and employing a diode for a circuit giving a bias to a gate electrode of the TR. CONSTITUTION:Resistors 2, 2', 4, FETs 1, 3, 3', 8, 10 and diodes 7, 9 are included in a differential logic circuit, which is connected between power terminals 5 and 6 and in order to give a gate level of a constant current generation FET 1, the diode 7, the FET 8, the diode 9 and the FET 10 are connected all in series and the gate level is obtained from a source of the FET 8. Since a current voltage characteristic between the anode and the cathode of the FET 8 is nonlinear, the anode-cathode voltage of the diode 7 in response to a drain-source current IDS of the FET 8 is only fluctuated to a degree proportional to the logarithm of the I of the FET 8 and nearly constant in the 1st order fluctuation range of the current of the circuit being the series connection of the diodes and the FETs. Thus, the circuit is made stable and the differential logic circuit whose logical amplitude is constant is obtained.

Title: Magneto-resistance effect type head
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1990-05-11
Abstract: PURPOSE:To suppress the generation of Barkhausen noises in reproduced waveforms and the fluctuation in the output level of a magneto-resistance effect type head (MR element) by forming the MR element to a circular annular shape which has no magnetic gap. CONSTITUTION:The MR element 11 consists of a ferromagnetic material, such as, for example, NiFe film. The MR element 11 is formed to the circular annular shape. The element is connected to a drawing out conductor layer 12 which is notched at a prescribed width and has a width t5 at both ends of a annular signal detecting region 16. The easy axis of the MR element coincides with the circumferential direction of the annular from the shape anisotropy of this MR element. Namely, the easy axis direction varies with the shape and coincides with the direction where the length is larger and in this case the circumferential direction of the infinite length. The MR element 11 is annular and the length thereof is not formed to the finite length with respect to the magnetization direction and, therefore, magnetic poles are not generated in the element and diamagnetic fields are not generated. Magnetostatic energy, therefore, decreases to zero and the element has the monodomain structure where magnetic walls are not generated. The fluctuation in the output level is prevented in this way.

Abstract: PURPOSE:To prevent variations in device characteristics by making an electrode for substrate bias with a material having easier ohmic contact with a substrate than an interior wiring material connected to diffusion layers on a semiconductor substrate wherein each component is ohmically connected by heat treatment. CONSTITUTION:Al wires 5 with Si are formed on a source and a drain on an Si substrate. The Al with Si around a scribed line section and the neighborhood is removed. Next, an electrode 7 for substrate bias by pure Al is made around the scribed line and the neighborhood. Next, heat treatment is applied at about 500 deg.C and for about 30min to complete ohmic contact with the wires 5 and diffusion layers 2 and that with the electrode 7 and the substrate 1. Wires 5 and the electrode 7 are covered with SiO2 8. The substrate has a low impurity concentration compared to the diffusion layers. Therefore, ohmic connection is normally hard to obtain. However, with pure Al used, each component will be ohmically connected together with interior wires by heat treatment under the same condition. Therefore, satisfactory ohmic connection will be obtained without deteriorating device characteristics.
