摘要： A laser beam is focused at positions on an optical axis of the optical pickup by a focusing device, corresponding to kinds of the discs which are different in thickness. The focusing device is moved along the optical axis. A photodetector is provided for receiving a laser beam reflected from the disc and for producing a focus error signal. A detector is provided for detecting the difference between the focus error signals, caused by the difference in thickness of the discs and the difference in focal point of the laser beam, thereby discriminating the kind of the disc.

摘要： The lithium secondary battery uses lithium or a compound containing lithium as an anode active material, and lithium nickel oxide as a cathode active material. This battery is produced to enhance the charge and discharge capacity. The lithium nickel oxide is prepared as follows. Nickel oxide which contains nickel of more than trivalence or a nickel salt which produces nickel of more than trivalence when heated, and lithium salt are mixed at an Li/Ni (molar salt ratio) of 1.0 to 1.5. After preheating the mixture, it is baked at a temperature of 680.degree. C. to 780.degree. C. in an oxygen atmosphere, thus producing a lithium nickel oxide. The primary differential absorption spectrum of the electron spin resonance of the lithium nickel oxide is a singlet (single line) when measured by use of an X band at a temperature of 77 K., and the line distance (.DELTA.Hpp) between the peaks is 140 mT or more. The intensity ratio of the main peak of the components other than the lithium nickel oxide and that of the lithium nickel oxide in a powder X-ray diffraction image is lower than 0.03. The Li/Ni ratio (atomic ratio) is above 0.9, and the grain size of the primary particles is below 1 .mu.m.

摘要： The present invention provides, as a material for a golf club face of a driver, an iron or the like, a titanium alloy which satisfies the regulation for a coefficient of restitution, and has high Young's modulus and tensile strength and also has excellent hot and cold workability. The titanium alloy for a golf club face according to the present invention comprises, in percent by mass, 1.0 to 3.5% of Al, 0.5 to 1.4% of Fe, 0.2 to 0.5% or O and 0.002 to 0.030% of N, and the balance of Ti with inevitable impurities, wherein an α-phase is strengthened by combined addition of O and Al, and inexpensive Fe is selected as a β-phase stabilizing element, leading to high strength and high Young's modulus in combination. The content of Al causing deterioration of hot workability is limited to a low value, leading to low rolling load during hot rolling, and thus flaws and edge cracking are unlikely to occur during hot rolling.

摘要： On the other hand, the possibility of estimating the dopant ratio of a metal element to each ceria crystalline particle using integral-width or half-width obtained by XRD was considered as follows: an XRD peak is shifted depending on the dopant ratio of La to ceria; when La increases, an XRD peak is shifted to a lower angle; in XRD performed on a raw material obtained by mixing ceria crystalline particles having different dopant ratio, peaks corresponding to the respective dopant ratio exist close to each other; as a result, a peak width is widened; accordingly, the dopant ratio of a metal element to each ceria crystalline particles are supposed to vary when integral-width and half-width obtained by XRD are large. Thus, it was revealed for the first time that integral-width and half-width obtained by XRD indicate variations in dopant ratio. It should be noted that from the direct proportional relationship between the dopant ratio x and the integral-width for dopant ratio ranging from 0.35 to 0.45, integral-widths obtained by XRD are derived to be 0.10 to 0.30 for dopant ratio ranging from 0.35 to 0.45, and half-widths are derived to be 0.10 to 0.30 similarly.

摘要翻译： 另一方面，使用通过XRD得到的整体宽度或半宽度来估计金属元素与每个二氧化铈晶粒的掺杂比率的可能性被认为如下：XRD峰值根据La的掺杂剂比率而偏移 二氧化铈 当La增加时，XRD峰移动到较低的角度; 在通过混合具有不同掺杂剂比率的二氧化铈晶粒获得的原料进行的XRD中，与各自的掺杂剂比例相对应的峰彼此接近; 结果，峰宽变宽; 因此，当通过XRD获得的整体宽度和半值宽度时，假定金属元素与每种二氧化铈晶体颗粒的掺杂比变化。 因此，首次揭示了通过XRD获得的积分宽度和半值宽度表示掺杂剂比例的变化。 应当注意，从0.35至0.45的掺杂剂比率的掺杂剂比x和积分宽度之间的直接比例关系，通过XRD获得的积分宽度导出为0.35至0.45的掺杂剂比为0.10至0.30 ，并且半宽度类似地导出为0.10至0.30。
