Title: Detecting circuit device
Inventor: OOKUBO TSUNEO
IPC: H03D1/18
Filed: 1982-03-19
Abstract: PURPOSE:To ensure the stable operation of a detecting circuit device, by DC coupled the AM detection output to an amplifier of the next stage after connecting a capacitor to a transistor (TR) for AM detection and at the same time connecting the TR to another one of different polarity. CONSTITUTION:An AM signal is fed to a terminal 11 and then amplified by an amplifier 12, and the output of the amplifier 12 is applied to the base of a TR13. Then the AM detection is performed by the charging/discharging function of a capacitor 14 provided to the emitter of the TR13. The detected signal is delivered to the collector of the TR13 and applied to the base of a TR22 to be amplified. Then an AM detection output signal is extracted from the collector of the TR22. In this case, the collector current of the TR13 has no change although the DC voltage of the emitter of the TR13 has a change due to variations of the AM signal input. As a result, the base bias of the TR22 has no change. Thus the stable operation is ensured for a wave detecting circuit device even in case where an amplifier is DC coupled to the AM detection output, i.e. a terminal 28.

Abstract: PURPOSE:To directly announce information to another center besides a supervisory center, which is determined in advance, in correspondence to a spot, where an abnormal signal is generated, by providing an identification device to identify the information, which are announced to the other center besides the supervisory center, and a device to transmit the information, which are identified by the device, to the other center in a terminal equipment. CONSTITUTION:In the cage of an elevator, sensors such as a sound speaking switch 2a, water supply/drainage equipment abnormality detection sensor 2a and a crime prevention sensor 2c are provided and connected to an annuciator 9 of a terminal equipment 1 in the building. In the annuciator 9, a change in the contact of each sensor is detected and prepares the abnormal signal. Then, the signal is sent to an identification device 10. In the identification device 10, it is identified whether the information are announced to other centers 5 and 6 besides a supervisory center 4 or not. In the case of the information to be announced, these abnormal information are transmitted by a facsimile communication equipment. Thus, the abnormal information are not passed through the supervisory center 4 but directly announced from the terminal equipment 1. Thus, the reception waiting state of announcement, which is caused by the concentration of the announcement to the supervisory center, can be avoided.
