Title: Battery switching-over circuit for electronic apparatus
Inventor: MIYANAGA TAKAO
IPC: H02J9/06
Filed: 1992-06-25
Abstract: PURPOSE:To reduce the size and cost of a battery switching-over circuit for electronic apparatuses, wherein the battery used as the power supply of a portable electronic apparatus is switched over to an auxiliary battery when the voltage of the battery is lowered, by performing logically the switchover to the auxiliary battery through a gate IC. CONSTITUTION:A gate IC 4 has the flow-out current larger than the current necessary for maintaining the operation of a specific part 3 of an electronic apparatus, whose power supply requires a backup. The gate IC 4 is used as a battery switching-over circuit, and an auxiliary battery 2 for the backup is used as the power supply of the gate IC 4. Ordinarily, the current from a main battery 1 is given via a diode OR circuit 5 to the specific part 3 requiring the backup, and the reduction of the voltage of the main battery 1 is sensed on the input side of the gate IC 4. When the voltage of the main battery 1 becomes not higher than the threshold voltage of the gate IC 4, the flow-out current of the gate IC 4, which has the auxiliary battery 2 as its power supply, is given via the diode OR circuit 5 to the backed-up load 3.

IPC: G01N21/17
Filed: 1987-07-07
Abstract: PURPOSE:To detect density of microorganisms at a high accuracy with the shape and size unavoidably uncertain, by a method wherein a suspension of a microorganism reaction tank is photographed to recognize and identify a microorganism area and a non-microorganism area and the density of the microorganism is computed based on a projection area of the microorganisms being computed. CONSTITUTION:An inflow sewage 3 and a return sludge 4 are introduced to an aeration tank 1. A suspension camera 11 is immersed into the aeration tank 1 and a density image of the suspension 9 to be taken is converted into a digital signal to be stored into a density image memory means 20. A correction image obtained by a density brightness correction means 30 is applied to an image recognition means 40 to separate and recognize active pollution and a liquid phase part and the number of all pixels in an area where active sludge exists is computed by a characteristic value computing means 50 to be stored into a characteristic value memory means 80. Projection area of the active sludge stored in the means 80 is outputted into a sludge density computing means 100 by judgement with an image recognition/judgement means 90 and the density of the active sludge as computed is outputted and displayed. Thus, the density of the sludge with the shape and size being unavoidably uncertain can be detected at a high accuracy.

Title: Phase demodulator
Inventor: TOMITA HIDEHO
IPC: H04L27/22
Filed: 1991-07-10
Abstract: PURPOSE:To directly demodulate a carrier PSK signal PSK-modulated by a digital signal without using an analog circuit. CONSTITUTION:A Baud timing signal (c) is converted into a synchronous Baud timing signal (d) synchronizing the first rising of the PSK signal (a) converted into a logical level in a zero-cross detecting equipment 1 by a sampler 2 in the demodulating circuit of a delay detection system. In the meantime, a ring oscillator 3 generates an output (e) in N taps where the phase of a frequency being the same as the carrier frequency of the PSK signal (a) is equally divided into N parts. The outputs (e) are latched by the synchronous Baud timing signal (d) in a latch 4. A point where the logical level of the mutually adjacent latch outputs (e) changes becomes phase information of the digital signal. Phase information is encoded in an encoder 5 so as to generate a demodulating output (g). The demodulating circuit of a synchronous detection system subtracts the offset phase being the output of a synchronous phase defining circuit from phase information so as to define the reference phase of the PSK signal (a).

Abstract: PURPOSE:To make an air leakage into a condenser simply and surely informable to an operator by detecting the discharge air weight flow separator tank, and comparing this flow rate with the discharge air quantity operated by load of a generator at time of operation. CONSTITUTION:A power plant is made so as to keep a vacuum in a condenser through the air ejection done by a vacuum pump. In this case, load of a generator is detected by a detector 6, and a leakage quantity of air to the generator load is found by a function generator 11. In addition, a deviation between the measured value found by a flow rate oscillator 3 and the flow rate found by the function generator 11 is found by a deviation computing element 7.

With this constitution, when a vacuum drop in the condenser is caused by the air leakage, this fact is informed to an operator at a central control room, making him perform the required operation aid.
