Title: Anti-skid control device
Inventor: MATSUURA MASAHIRO
IPC: B62D6/00
Filed: 1994-06-03
Abstract: PURPOSE:To provide an anti-skid control device in which a stable control is possible even in an anti-skid control during turning. CONSTITUTION:When the wheel speed VW2 of a right front wheel is smaller than the wheel speed VW1 of a left front wheel and also a difference in speed between the front and rear wheels is small, it is judged that a vehicle is in turning condition at a time of t20. Also a cumulative value SIGMADELTAVX of 20 times of right and left wheel speed differences DELTAVX is calculated until the time of t21 and, when a lateral acceleration GY is obtained, the pressure reducing reference set width SRe12 of the right front and right rear wheels set at an initial pressure reducing reference set width SRe1 is expanded by an amount of a pressure reducing reference correction value DELTASRe1, as shown by dashed lines. By this, for the pressure reducing reference set width SRe12 not expanded, the wheel speed VW2 is reduced more than a pressure reducing reference at a time of t22 and the pressure reducing control of a brake pressure (brake oil pressure) is executed. Thus, when it is expanded, a brake pressure is maintained even after the time t22, and thus it is prevented for a braking distance to be extended.

Title: Method for reducing magnetism resistant force of liquid-phase epitaxial garnet film
Inventor: HIBIYA TAKETOSHI
IPC: H01F41/28
Filed: 1979-09-25
Abstract: PURPOSE:To reduce the magnetism resistant force by annealing a liquid-phase Ga epitaxial film containing Bi ions Bi<3+> at a 24C position at 800 deg.C or more. CONSTITUTION:A liquid-phase Ga epitaxial film containing Bi ions Bi<3+> at a 24C position is annealed at a temperature of 800 deg.C or more. The magnetism resistant force of a Bi substituted liquid-phase epitaxial layer is generally high. The magetism resistant force by a magnetic domain modulating method using an AC magnetic field in the liquid-phase Ga epitaxial film of Tm2.4Bi0.6Fe3.85Ga1.15O12 is 2.5 Oe. In the case the magnetism resistant force is large as mentioned above, there is a drawback that the printing pattern is remained even after the magnetic tape has been removed from the Ga film. The large magnetism resistant force of Bi substituted Ga is caused by irregular placement of the Bi ion Bi<3+> whose radius is large at the position 24C of a Ga lattice and by partial distortion of the lattice. Such distortion can be eliminated by the annealing, thereby the magnetism resistant force can be reduced.

Title: Distributed/integrated type vibrating table
Inventor: KOIKE AKESHI
IPC: G01M7/02
Filed: 1995-04-24
Abstract: PURPOSE: To make it possible to provide a table as the large table as required even for the vibration test of a large structure with the relatively light-weight construction by moving a plurality of all vibrating tables in synchronization. CONSTITUTION: A plurality of relatively small vibrating tables 1 are utilized, and all the small vibrating tables 1 are moved in synchronization. Thus, the entire vibrating tables are operated equivalently as one large vibrating table. For example, the vibrating tables are constituted of 3×3=9 tables. When each vibrating table 1 is slid or turned and the interval between the tables is expanded, the tables can be utilized as the large vibrating table. In the case for a small-scale body under test, only one or limited number of the vibrating tables 1 are selected and utilized. Thus, it is not necessary to operate all number of the vibrating tables 1. Therefore energy saving is achieved. In this case, the respective vibrating tables are divided into the groups, and a plurality of the independent tests can be performed at the same time.  Furthermore, even for one body under test, each vibrating body 1 can be operated so as to have mutual correlation each other when a plurality of required input points are provided.
