Title: Preparation of insb single crystal
Inventor: TERAJIMA KAZUTAKA
IPC: C30B29/40
Filed: 1980-02-15
Abstract: PURPOSE: To prepare a high quality InSb single crystal, by pulling the InSb single crystal keeping the vertical temperature gradient just above the molten liquid and the rate of pulling at specific levels.  
     CONSTITUTION: In the preparation of InSb single crystal by the pulling process, the vertical temperature gradient just above the molten liquid surface is maintained at 35W105°C/min, and the rate of pulling is selected to ≥5mm/hr. Preferably, the temperature distribution curve has a plateau region of ≥1cm in length beginning from a point within 1cm from the surface of the molten liquid and having the temperature deviation of ≤5°C. In the case of the solid line B in the figure, the temperature gradient just above the surface of the molten liquid can be obtained from the region I. The gradient can be reduced by placing the surface of the molten liquid near the center of the oven.

Title: Manufacture of metal hydride storage battery
Inventor: KANEKAWA IKUO
IPC: H01M4/26
Filed: 1991-02-08
Abstract: PURPOSE:To sufficiently exhibit initial cycle performance of a metal hydride battery and enhance a cycle lifetime by using a negative electrode made of a hydrogen occluding alloy. CONSTITUTION:A hydrogen occluding alloy electrode is used as a negative electrode. Hydrogen is previously occluded in an alloy for the negative electrode in a hydrogen atmosphere in an activating treatment. Hydrogen is discharged until a hydrogen occluding quantity of the hydrogen occluded alloy becomes 1% or less than a nominal volume of the negative electrode. Consequently, it is possible to delay full charge of the negative electrode at the time of overcharge so as to sufficiently consume gas flowing from a positive electrode in the negative electrode, thus obtaining an adequate battery capacity after an initial cycle and enhancing an overcharge characteristic and a cycle characteristic.
