Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an abnormal action and carry out an exact opening/closing action by providing each insulative projection dots on opposed electrode sheets, providing a mark having a predetermined position relation to the dots and adjusting a position between dots of both electrode sheets. SOLUTION: Insulative projecting inner dots 14 uniformly disposed to keep a gap with A at a constant are uniformly disposed on B of electrode sheets A, B overlapped through a spacer C and outer dots 4 outwardly projected are uniformly disposed on A. When the outer dots 4 are pressed, the electrode sheet A is pushed into a gap of the inner dots 14 and is adjacent or contacted to the electrode sheet B to become a closing action. Accordingly, the inner dots 14 and the outer dots 4 are disposed such that they are overlapped and it is necessary to keep a predetermined position relationship-p. Therefore, a plurality of phase marks 5 and marks 15 such as apertures, projections and coloring having a predetermined position relationship with each dot are provided at an area other than the area at which the electrode is formed and a position adjustment of both dots 4, 14 is easily and exactly carried out making the marks as a standard.

Title: Transmission control method for plotting communication system
Inventor: SHIMIZU SUSUMU
IPC: H04N7/15
Filed: 1989-10-20
Abstract: PURPOSE:To avoid the collision of a transmission data even when simultaneous transmission is executed from each equipment by deciding the order of token acquisition of each plotting communication terminal equipment in response to number of times of reception of a start command. CONSTITUTION:Plotting communication terminal equipments A1-C3 are interlinked in a way of capable of inter-communication via an exchange 4. An equipment sending a start command receives sequentially the start command from an equipment sending the start command thereafter and the number of times of reception is smaller in the order of equipments from which the start command is sent. Since the carrier monitoring time is set longer at transmission as the number of time of reception is larger, when simultaneous transmission takes place from each equipment, the equipment whose carrier monitoring time is longest, that is, the equipment sending the start command at first acquires the token latest. Thus, even when transmission takes place simultaneously among plural terminal equipments, the token is given to a terminal equipment whose number of times of reception of the start command is least and the collision of the transmission data is avoided.
