Abstract: PURPOSE:To make it possible to diagnose the life of a sealed lead acid battery with excellent reliability and at low cost, by detecting the plate deformation of the point of intersection of a center portion in the longitudinal direction of an electrode group with a center portion in the vertical direction of the electrode group. CONSTITUTION:A non-contact type displacement sensor 3 is attached to a sealed lead acid battery so as to detect the plate deformation of the point of intersection of a center portion in the longitudinal direction of an electrode group with a center portion in the vertical direction of the electrode group, for performing diagnosis of the life of the battery. For example, the non-contact type displacement sensor 3 and a controller 4 connected to the sensor 3 are used and a voltage of 100 volts AC is applied to the controller 4, so that a voltage output corresponding to the distance from the non-contact type displacement sensor 3 to a positive plate 1 is produced. The life of a sealed lead storage battery can thus be diagnosed with excellent reliability and at low cost.

Title: Receiver
Inventor: EGAMI TAKESHI
IPC: H04B7/26
Filed: 1991-10-31
Abstract: PURPOSE:To provide the receiver ensuring the linearity and detecting accurately a signal level of a reception signal even in a mobile body communication system by digital modulation. CONSTITUTION:When a reception signal is demodulated in a reception slot of its own station, a gain control changeover circuit 1-14 forms an AGC loop. Thus, a reception circuit ensures the linearity regardless of a reception level. Moreover, when the reception signal level is detected in other slot than that of its own station, the gain control changeover circuit 1-14 gives a constant voltage to a control terminal of a gain control amplifier 1-7 to fix the gain of the gain control amplifier 1-7. Thus, a reception level detection circuit 1-13 accurately detects the reception level.
