    摘要： Fine-grained nickel electrode active material, each of which contributing to electrode reaction; production method of the fine-grained nickel electrode active material; and a nickel alkali storage cell of high capacity which is excellent in over discharge characteristics. In order to produce the fine-grained nickel electrode active material, fine-grained nickel hydroxide is precipitated by adding a given amount of alkali to solution in which at least a nickel compound is dissolved while the solution is stirred. Each of the fine-grained nickel hydroxide has pores with 20 vol % or more of a combined volume of the pores being composed of pores of diameter 60 .ANG. or greater. Next, a given amount of alkali is gradually added to suspension including the fine-grained nickel hydroxide and dissolved cobalt compound so that cobalt hydroxide is precipitated on the external surface of the fine-grained nickel hydroxide. The fine-grained nickel electrode active material is produced in the above mentioned way. Each of the fine-grained nickel electrode active material comprises a nickel hydroxide and cobalt oxide having distorted crystal structure and oxidation number higher than +2. The nickel hydroxide has pores whose diameters are 60 .ANG. or greater. And the volume of such pores amounts to 20 vol % or more of the combined volume of all of the pores.

    摘要： A alkali storage cell includes a non-sintered type nickel electrode which includes a highly efficient nickel hydroxide active material and which causes no capacity decrease during an over-discharge operation. The nickel electrode contains an active material composed of nickel hydroxide, a solid solution of at least one of zinc, cadmium, magnesium, and calcium which are added to the nickel hydroxide, and cobalt compound layers which are formed over the surfaces of particles of the nickel hydroxide. The cobalt compound layers have an oxidation number of larger than 2 and a disordered crystal structure. Such an active material can be manufactured by mixing nickel hydroxide powder containing a solid solution of at least one of zinc, cadmium, magnesium, and calcium with either metallic cobalt or a cobalt compound, and subjecting the mixture to heat treatment in the presence of oxygen and alkali. Another production method is to precipitate a cobalt compound over the surfaces of the nickel hydroxide powder containing a solid solution of at least one of zinc, cadmium, magnesium, and calcium so as to form cobalt compound layers, before subjecting it to the heat treatment in the same conditions.

    摘要： A nickel active material for an alkali storage cell whose surface is covered with a cobalt compound, wherein the diffusion and permeation into the nickel hydroxide mother particles of cobalt compound during excessive discharging, which act to reduce the active material efficiency and the excessive discharging characteristics, are prevented. This is achieved by having a covering layer, including one or more of the following metal compounds; an aluminum compound, a magnesium compound, an indium compound and a zinc compound, in addition to a cobalt compound, formed on the surface of a mother particle of nickel hydroxide, and by heat treating the covered mother particles in the presence of alkali and oxygen so as to convert the cobalt compound into a compound of cobalt where an oxidization number of cobalt is greater than 2.

    摘要： In a method of manufacturing a nickel active material, nickel hydroxide particles coated with cobalt hydroxide are put on the mesh disk 4 of the fluidized granulator 1. Then, hot air is continuously supplied from outside through the hot air inlet 5, while air inside the fluidized granulator 5 is continuously emitted through the air outlet 8. At the same time, the nickel hydroxide particles are stirred with the stirring fan 3 and further dispersed by a hot air current. In this condition, an alkali aqueous solution is sprayed on the nickel hydroxide particles through the spray nozzle 7 by the pump 9. After the spray, the nickel hydroxide particles are further stirred in hot air so as to complete an alkali heat treatment.

    摘要： Generally, a photoacoustic signal has a wavelength longer than a general ultrasonic signal. That is, it does not matter even if at the time of acquisition of the photoacoustic signal, an element pitch of a probe is several times as large as at the time of acquisition of the ultrasonic signal. Thus, at the time of acquisition of the photoacoustic signal, a plurality of neighboring elements in a receiving element array are collectively considered as one element, and a phasing process is performed. As a result, the same effect as a plurality of phasing addition circuits are disposed in parallel is obtained, and not only a phasing addition process of the photoacoustic signal but also image reconstruction can be performed in real time at a high speed.

    摘要翻译： 通常，光声信号的波长比通常的超声波信号长。 也就是说，即使在获取光声信号时探头的元件间距是获取超声波信号时的几倍也是无关紧要的。 因此，在获取光声信号时，将接收元件阵列中的多个相邻元件统称为一个元件，并执行定相处理。 结果，获得与多个相位相加电路相同的效果并行设置，不仅可以高速实时地执行光声信号的相位加法处理，还可以进行图像重构。
