Title: Alkali battery
Inventor: KAWAGUCHI MASAO
IPC: H01M4/06
Filed: 1988-11-28
Abstract: PURPOSE:To reduce diversity in battery capacity by making bulk density and grain size of spherical amalgam zinc powder to be used for a negative electrode those prescribed so as to improve weighing accuracy thereof. CONSTITUTION:Amalgam zinc powder has its bulk density in the range 5 to 4.5g/cc and its grain size in the range 40 to 150Mesh while a difference of the upper limit value and the lower limit value of grain size is in the range of 40Mesh. Weighing of the amalgam zinc powder to be used for one battery is so performed that the amalgam zinc powder dropping of itself from the bottom of a hopper is cut by rubbing with a weighing plate having a hole of fixed volume in order to measure the volume to be filled in this hole. The amalgam zinc powder is cut by rubbing causing no unevenness on its upper layer surface part always flatwise at the hopper bottom part so that weighing diversity is suppressed. Thereby, a negative electrode having correct volume is secured so that diversity in battery capacity can be suppressed.

Filed: 1989-11-20
Abstract: PURPOSE:To prevent occurrences of slip by changing output of a required heating lamp group or either a lamp in the above lamp group according to difference in detecting temperatures between respective temperature sensors and then, decreasing difference in the detecting temperatures. CONSTITUTION:On the occasion of raising the temperature of a susceptor up to a prescribed temperature, respective temperature controllers 251-253 change each resistance value of output change apparatuses 26 into a prescribed value that is provided in advance so as to obtain optimum output at the time required for a process and then, lamp drivers 27 of infrared lamps 23 are controlled. Further, when the temperature of its susceptor is kept at a required temperature or even its temperature lowers with temperature gradient, the lamp drivers are controlled in the same manner. For example, when temperature difference occurs between thermo couples 241-243 in the case where the temperature of the susceptor rises, respective temperature controllers 251-253 select a heating lamp group in which output change is required according to a pattern that is set in advance on the basis of detecting temperature difference or the above controllers select either of prescribed lamps in the required heating lamp group. Then, output is changed and detecting temperature difference is reduced to a required value. The temperature uniformity of the susceptor is always kept and occurrences of slip are thus suppressed.
