Control so as to lower the luminance of the picture slowly corresponding to the change in the slow direction of the control signal is applied. In such a way, it is possible to surely prevent the doming occurring without generating the unnatural change of luminance.

Filed: 1985-09-11
Abstract: PURPOSE:To prevent the defect in the thick-walled part of a casting and to improve the durability of a metallic mold by providing a vent hole from the outside to the casting mold near the thick-walled part of the casting. CONSTITUTION:The vent hole 2 into which the air flow from the outside can enter is provided to the metallic mold 3 as a back metal and plural deaerating holes 5 are disposed thereto.

Abstract: PURPOSE:To restrict increase of internal resistance of a battery due to a charging/discharging cycle, and to lighten weight of a battery, and to improve lifetime of a battery to realize a high energy density by using a current collecting lid made of impermeable amorphous carbon or graphitic carbon to seal a container. CONSTITUTION:A negative electrode current collecting lid 8 is provided in the upper part (negative electrode side) of a container 1 through an insulating alphaalumina layer 9. This alpha alumina layer 9 prevents short-circuiting between the negative electrode current collecting lid 8 and the container 1.

Increase of internal resistance of a battery due to a charging/ discharging cycle is thereby restricted, and lifetime of a battery can be improved. The carbon material has a small gravity, for example, at 1.5-2g/cm<3> and the mechanical strength nearly equal to that of metal. Weight of a battery can be thereby lightened, and as a result, lifetime of a battery can be improved, and a high energy density is obtained.
