Abstract: PURPOSE:To eliminate a position shift due to the tilt of a pen or the position of eyes by shifting the dot coordinates of a display matter in the optional direction to the detection coordinates of a tablet. CONSTITUTION:A liquid crystal display LCD2a is connected to a display memory 8 via a control circuit 7, and the open/close of the pressure switch of an input pen 1 is detected by a control circuit 10 for an electromagnetic induction tablet 2b. Then the result of detection is delivered to a CPU9, and a position correction mode key 3 of the memory 8, a cursor key 4 and a release key 5 are connected to the CPU9. When a hendwriting operation is carried out on a display screen by means of the pen 1, the corresponding switch is turned on. The detected areas of magnetic fluxes are regarded as coordinates by the tablet 2b. Then these coordinate values are corrected by the registered correction values. Furthermore this correction data is written to the memory 8 and at the same time a prescribed dot of the LCD2a is turned on for display of the locus of the pen 1. When one of keys 4 is pushed, the addition/subtraction is given to the correction value.

Filed: 1991-09-24
Abstract: PURPOSE:To prevent breakage of a solid electrolyte tube by forming an inner side of a bottom plate of a cathode container in a protruding form, and eliminating storage of sulfur at an interval between the bottom plate of the cathode container and a solid electrolyte tube. CONSTITUTION:In a fully charge-completed condition of a sodium-sulfur battery, most sodium Na is stored in an anode chamber R2.
