Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To accurately reproduce a signal by eliminating the existence of plural domains within a spot diameter of a laser beam at the time of reproducing the signal. SOLUTION: In this magneto-optical disk device, an inverted region detecting circuit 13 detects a length L of the region made to uprise to the temperature or higher at which a magnetic film of a magneto-optical recording medium 1 can be inverted in magnetization by an external magnetic field by a laser beam, based on a magneto-optical signal detected by an optical head 2. A driving signal generation circuit 15 generates such a driving signal as an interval between domains formed on the magneto-optical recording medium 1 becomes longer than L based on the record signal modulated to a predetermined method by a modulation circuit 16 and the detection result of the inverted region detecting circuit 13 outputted from a control circuit 14. And, based on the generated driving signal, the signal is recorded by driving a semiconductor laser in a magnetic head or an optical head 2.

Abstract: PURPOSE:To make it possible to grow an SiO2 film selectively and excellently by dipping a substrate on which a resist film is selectively formed in aqueous solution obtained by adding an additive for consuming HF into aqueous solution of SiF6 wherein SiO2 powder is dissolved and saturated in a supersaturated state. CONSTITUTION:A material wherein a diffused layer 102a is selectively formed on a silicon Si substrate 101a is made to be a substrate. A photoresist film 103a is formed on the diffused layer 102a.

Abstract: PURPOSE: To easily change a print mode by detecting a count of printing dots per one scanning, and controlling a printing means to change a thinning rate for data to be printed based on the detection result. CONSTITUTION: A printer apparatus is provided with a printing head 2, a carriage motor 11, a paper feed motor 12, etc., operating with an HQ mode giving priority to the image quality and an HS mode giving priority to the printing speed.

Abstract: PURPOSE:To stabilize the braking by suppressing the control at the area where the behabior of a vehicle is made unstable (a condition of spinning tendency and the like) by this control, in a braking force control system by means of a braking force difference generated between the left side and the right side. CONSTITUTION:In case of a yaw rate F/B system, a controller determines an object differential pressure DELTAP (S) between the left side and the right side by finding a yaw rate difference value DELTA (d/dt) phi of the difference between an object yaw rate (d/dt) phiref, and an actual yaw rate (d/dt) phi (S 113 and 114). The object value (d/dt) phiref can be set based on a steering angle delta and a car speed V (S110 to 112). Object wheel cylinder pressures of the left side and the right side wheels are set depending on the object differential pressure DELTAP (S), but prior to the setting, the DELTAP(S) is corrected according to the actual yaw rate (d/dt) phi, for example, and an object W/C pressure is determined by the corrected DELTAP(S) (S115 and 116). In this correction, when an excessive yaw such an over steering of the steering in the condition that the yaw rate is large and a side slide is generated, for example, the controller executes a correction to reduce the difference between the left side and the right side.
