IPC: G06F3/0488
Filed: 1994-07-29
Abstract: PURPOSE:To provide a coordinate input device capable of executing accurate coordinate input. CONSTITUTION:Vibration inputted from a vibration pen 3 to a vibration transmitting plate 8 is detected by a vibration sensor 6 and a transmission distance from a vibration source and coordinates based upon the distance are calculated by a signal waveform detecting circuit 9 and an arithmetic and control circuit 1.

When an error is included, the length of one wavelength is added to the transmission distance of a sensor having the highest probability of including an error and most close to the vibration source out of plural calculated transmission distances, its coordinates are calculated again and the judgement of an error is repeated. A sensor most far from the vibration source can also be selected as a sensor corresponding to a transmission distance including an error. Thus error detection controlling preparatory correction can quickly be executed by simple constitution and accurate coordinate input can be attained.

Title: Control of concentration of liquid toner for electrostatic recorder
Inventor: MORISHIGE TAKAYOSHI
IPC: G03G15/10
Filed: 1990-07-06
Abstract: PURPOSE:To keep the concentration of toner constant with higher accuracy by supplying toner particles to liquid toner every time the counted value of a dot counting means exceeds a set value and decreasing the dot counted value by a specified value in accordance with an output from a means for counting the number of plotted lines. CONSTITUTION:A volatile substance is used as solvent for dissolving the toner, and the evaporation of the solvent is proportioned to the number of plotted lines. Namely, as the number of the plotted lines gets larger, the solvent is gradually evaporated and the liquid toner becomes thicker and thicker. Then, the plotted lines are counted by the line number counting means 14 and the counted value (m) for controlling toner supply timing is decreased in accordance with the counted value. Therefore, the toner supply timing is delayed in accordance with the number of the potted lines and the concentration of the liquid toner is controlled so that it becomes thinner. Thus, the concentration of the liquid toner is always kept constant and an electrostatic recorder in which the unevenness of printing does not occur is obtained.
