IPC: H01J47/02
Filed: 1986-09-29
Abstract: PURPOSE:To reduce the amount of floating capacity as well as to aim at abatement in microphonic noise and a high-frequency noise of a preamplifier, by forming either of a signal electrode plate or a high-tension impressing electrode plate into a shorter one.

Title: Communication method
Inventor: HARA HISAFUMI
IPC: H04L1/08
Filed: 1994-08-30
Abstract: PURPOSE: To easily recognize contents even when the accurate reception of a message is impossible by discriminating the contents of the message based on the number of times of the reception of the message or/and a transmission interval. CONSTITUTION: For instance, it is decided to transmit the message that a device 18 to be monitored is normally operated twice with the time interval (t) of one second, for instance, and to transmit the message that the other device 18 to be monitored is not operated for three times with the prescribed time interval (t) each. Such discrimination is relatively easily performed even under conditions that the text of the message is processed as a message error. Thus, the number of times of the transmission of the message, that is the number of times of repetition, is discriminated and it is recognized that the device 18 to be monitored is normally operated when it is repeated twice and that the device 18 to be monitored is in an non-operational state when it is repeated for three times.
