Title: Active suspension device for vehicle
Inventor: KISHIMOTO HISAHIRO
IPC: B60G17/015
Filed: 1990-06-20
Abstract: PURPOSE:To restrain the initial roll of a car body at the time of turning so as to improve the operational stability by continuously varying the distribution ratio of the actual load travel and the predictive load travel according to the degree of a steering angle speed of a steering handle. CONSTITUTION:When a car is turned, from a detection signal of a lateral G sensor 31, the actual load travel  W1 seen on right and left sides of a car body 7 is calculated. From detection signals of a handle angle sensor 33 and a car velocity sensor 34, the predictive load travel  W2 of the car body 7 is calculated by an arithmetic circuit. The distribution ratio gamma is calculated from a car velocity V, a steering angle thetaH and a steering angle speed deltaH by an arithmetic circuit. When a steering handle is steered, the steering angle deltaH is large and a car is about to be turned, the distribution ratio gamma is small, so that the percentage which the predictive load travel W2 occupies is increased. In the turning transition period, the oil pressure of each hydraulic actuator 14 is controlled according to the predictive load travel  W2 not according to the actual load travel  W1, the response delay is large, whereby even if a car turns suddenly, the initial roll of the car body 7 can be prevented effectively.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide an information-recording apparatus and an information- reproducing apparatus which can correctly reproduce last code data of a data sector even when information is recorded without any relation among data sectors in a DVD-RAM (DVD random access memory) demodulating the information recorded with an 8/16 modulation according to an 8/16 demodulation. SOLUTION: In recording information to a DVD-RAM after modulating by 8/16, a 16-bit postamble (PA) 25 including state information necessary for demodulating last 16-bit code data of a data sector 22 is added immediately after the data sector 22. When the information is to be reproduced, the last code data of the data sector 22 is reproduced with the use of the PA 25. When data recorded to the DVD-RAM is to be reproduced by a demodulator for a DVD-ROM (DVD read only memory), a part of the PA and a part of a leading sync of the data sector are coupled thereby to obtain the state information to reproduce the last code data of the data sector 22.

Abstract: PURPOSE:To improve use environmental characteristics by forming an upper barrier layer in such a manner as to have an intermediate surface layer the constituting atoms of which are Si, C, H, and F and forming the extreme surface layer the main constituting atoms of which are C, H and F thereon. CONSTITUTION:The concn. of the Si atoms on the intermediate surface layer 4a of the upper barrier layer 4 is gradually decreased from the boundary with the potential holding layer 3 toward the surface direction and is decreased to a low concn. of <=0.1% in, for example, the extreme surface layer 4b. The concn. of the C atoms is distributed by increasing the concn. thereof toward the surface direction. In addition, the concn. of the H atoms is so distributed as to be increased continuously toward the extreme surface layer 4b of the upper barrier layer 4 and the concn. of the H in the extreme surface layer 4b is increased to, prescribed 15-50%, by which the H atoms are dangling-bonded and are electrically inactivated. The H atoms and a small ratio of the F atoms are made to coexist in order to decrease the adverse influence that the dangling bonds of the Si-C and C-C exert on the photosensitive characteristics. The F atom concn. of this case is specified to 1-100%. The use environment characteristic is improved in this way.

IPC: G11B15/665
Filed: 1995-06-28
Abstract: PURPOSE: To apply constant tension to a tape regardless of any wound diameter of a reel during operation and to eliminate damage to the tape by calculating a tape winding diameter from a reel rotation frequency at the unloading and performing torque control on a reel motor in response to this calculation. CONSTITUTION: A tape length drawn out at the tape loading and a frequency generated during this time by rotating the reel are detected by a frequency generator 21, and are stored in a memory of a microcomputer 24. When unloading, a wound diameter of the reel is calculated by the microcomputer 24 from an output value of the frequency generator 21 at this supply reel 6 and a tape drawn-out length during loading. Moreover, a current for giving torque to the supply reel motor is decided according to a wound diameter of the supply reel 6, and torque of the supply reel motor is controlled, and then the unloading operation is started up. By this method, irrespective of any wound diameter during the operation of the device, the constant tension can be applied to the tape, and no damage to the tape occurs even if the unloading operation is performed under any circumstances.

Filed: 1983-09-07
Abstract: PURPOSE:To obtain carrageenan provided with counter-cation species having good heat stability and solution clarity, by treating carrageenan in an undissolved state with a weakly acidic solution and treating it with an alkaline solution. CONSTITUTION:Carrageenan in an undissolved state is first treated with a weakly acidic solution. This carrageenan is treated with a hydrophilic organic solvent/water mixture containing an alkali of a desired cationic species and having a concentration at which the carrageenan is not dissolved. By the alkali treatment, the counter cations of the carrageenan are converted from an acid form to a desired cationic species, and at the same time the heat stability can be improved by the alkali. The desirable acids include those which can solubilize calcium, such as hydrochloric or nitric acid. The desirable alkalis used in the alkali treatment are potassium hydroxide when potassium is desired as the cation, and sodium hydroxide when sodium is desired as the cation.
