Title: Titanium alloy having excellent corrosion resistance
Inventor: TAKI CHIHIRO
IPC: C22C14/00
Filed: 1988-01-25
Abstract: PURPOSE:To improve the corrosion resistance and economical effect of the subject alloy by adding small amounts of Ru to a Ti-Ni alloy and providing it with specific compsn. CONSTITUTION:The Ti alloy is constituted of, by weight, 45-60% Ni, 0.01-2.0% Ru and the balance consisting of Ti. At the time of comparing the Ti alloy with a Ti-Ni alloy to which Pd is added, the effect on the improvement of the crevice corrosion resistance is more excellent when Ru is added to the alloy than Pd is added thereto. The above Ti alloy is more excellent even in the aspect of economical effect since it can be well done only by adding small amounts of Ru more inexpensive than Pd thereto in spite of adding Pd in order to obtain equal corrosion resistance. The Ti alloy furthermore shows excellent corrosion resistance in the soln. contg. Cl ions and the nonoxidizing soln. such as HCl and H2SO4. As for the addition amounts of Ru, in the case of <0.01%, the improvement of the corrosion resistance is not expected, and in the case of >2.0%, the corrosion resistance to be expected can not be obtd. for the addition amounts and the economical effect is thinned.

Title: Magneto-optical recording medium
Inventor: IKEDA ETSURO
IPC: G11B11/105
Filed: 1993-01-28
Abstract: PURPOSE:To restrain that the characteristic of the title recording medium is deteriorated and to enhance the external magnetic field sensitivity of the recording medium by a method wherein a region containing oxygen is formed between a recording layer and a dielectric layer or a reflection layer and the region containing oxygen of the recording layer is set to a specific range or lower. CONSTITUTION:In an Auger profile in the depth direction, the average peak height of Si is found when a dielectric layer is composed of Si3N4, the average peak height of Zn is found when it is composed of ZnS, and a position in which respective peaks are 1/2 of the average peak height is found on the side of the interface with a recording layer. The average peak height of a transition metal for an RE-TM magnetic film is found also on the side of the recording layer, and a position in which the peak of the transition metal becomes 1/2 of the average peak height is found on the side of the interface with the dielectric layer, and the middle point of the two positions is used as the interface. In addition, a region containing oxygen. i.e., an intermediate layer, is formed between the recording layer and the dielectric layer or a reflection layer. However, when the intermediate layer creeps deeply into the recording layer, the characteristic of the RE-TM magnetic film of the recording layer is spoiled. Consequently, it is arranged that the foot of the signal of oxygen in the Auger profile does not creep into the recording layer at 150Angstrom  or higher.

Abstract: PURPOSE:To prevent the generation of erroneous alarm by altering a detection area by laser light according to a radius of curvature of a turning path in running on the turning path from the detection results of a steering sensor. CONSTITUTION:In a turning path, an alarm judging area, namely, an area for detecting whether a vehicle exists or not ahead is changed for an area for detecting no reflector of a guard rail by laser beams 16a, 16b and 16c. This means that alarm judging areas S1, Sc and Sr of the laser beams 6a, 16b and 16c are changed according to a radius of curvature of a road which is determined based on a steering angle detected by a steering sensor. It should be noted that the alarm areas of the laser beams 16a, 16b and 16c can be determined from a relationship between the radius of curvature of the road and the judging areas obtained previously. Moreover, when no steering angle is inputted, a command is provided to a laser radar unit from a control unit to detect an object ahead in a detection area the same as that of the straight travelling state.
