Title: Remote monitoring device
Inventor: YAMAMOTO ITSUROU
IPC: H04B17/40
Filed: 1982-05-11
Abstract: PURPOSE:To reduce number of components with common monitoring signals and to improve the reliability and profitability, by switching on and off failure alarm contacts in the timing assigned to each terminal station from a terminal station when a failure takes place in the terminal station. CONSTITUTION:When a terminal station in failure exists, a failure alarm contact 7c of the terminal station is on/off-controlled with a control circuit 7d periodically. Since the terminal station in failure intermits a supplied monitoring signal in the period of the failure alarm contact 7c, the monitoring signal is folded to a master station 1 via a line 8. A detector 11 in the master station 1 detects the supplied monitoring signal and the time interval of the detection signal is detected by a time detector 13. Since the time interval depends on each terminal station, the time detector 13 discriminates the terminal station in failure from this time interval and displayes the result on a display 12.

Title: Cell voltage detection circuit and battery voltage detection device
Inventor: KUDO AKIHIKO
IPC: G01R19/165
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To secure necessary voltage detection accuracy by providing a current conversion circuit that has an amplifier and a resistor forming a feedback loop and converts a cell voltage into a current, and an output resistor of which one end is connected to the negative terminal of a battery pack, and the other end is connected to the output of the current conversion circuit, and with which the voltage is detected as the cell voltage. SOLUTION: A feedback loop is formed so that a measurement cell voltage Vc equals a voltage between both ends of a current detection resistor R1. A source current Is flowing through the current detection resistor R1 becomes a drain current Id as it is because the gate current Ig of a P-channel FET is nearly zero. Therefore, the drain current Id flows through an output resistor R2 connected to the negative terminal of a battery pack, a voltage proportional to the cell voltage is generated across it, and the voltage is output on the basis of the negative terminal of the battery pack. In this case, provided that the resistance value of resistor R1 equals that of the resistor R2, the cell voltage is output as the voltage on the basis of the negative terminal of the battery pack.

Abstract: PURPOSE:To improve flatness by selectively forming a first insulating film on lower layer wirings, covering the lower layer wiring side walls with a second insulating film, burying low permittivity material between the lower layer wirings, and connecting the lower layer wirings with the upper layer wiring via a through hole. CONSTITUTION:Lower layer wirings 102 are covered with a first insulating film 103 selectively formed on the lower layer wiring metal 102 on a semiconductor substrate 101, and a second insulating film 105 covering at least the side walls of the lower layer wirings 102. The region where the lower layer wirings do not exist is filled with a film 106 formed by spreading material whose relative permittivity is 2-3. A third insulating film 107 is formed on the whole part of the substrate 101 so as to cover the upper surfaces of the film 106 and the film 103, and sealing is performed. The wiring 102 is electrically connected with the upper layer wiring 109 via a through hole 108 formed in the film 107. By this structure, the low permittivity material formed by a spreading method or the like does not directly come into contact with the wiring. Since the low permittivity material is buried, superior flatness can be obtained.
