The pH values of the reactors in the height direction are measured by pH meters 7a, 7b...7n and the treatment capacities of the anaerobic reactors are operated on the basis of pH distribution by an operation apparatus 9. Subsequently, the inflow waste water to the anaerobic reactors 6a, 6b...6n is distributed corresponding to the treatment capacities. By this method, the treatment capacity of each anaerobic reactor can be directly determined and control can be performed with high accuracy.

Filed: 1986-06-02
Abstract: PURPOSE:To protect an output transistor(TR) against destruction when an output circuit is short-circuited by providing a comparator which compares the output voltage of a push-pull amplifier with a reference voltage. CONSTITUTION:An amplifier circuit block 1 which drives the output stage of the push-pull amplifier, the push-pull amplifier consisting of output TRs 2 and 3 driven with the output of this amplifier circuit block 1, the comparator 7 which compares the voltage at the output terminal 4 of the push-pull amplifier with the reference voltage of a reference voltage source 6, and a control circuit 71 which turns off the output circuit of the push-pull amplifier when the comparator 7 decides that the output voltage of the push-pull amplifier is lower than the reference voltage are provided. Therefore, even when the output terminal of the push-pull amplifier is grounded, no large current keeps on flowing to the output TRS because the output TRS constituting the output stage of the push-pull amplifier turn off.

Abstract: PROBLEM TO BE SOLVED: To prevent a pile for constructing a new retaining wall from being driven by going over a boundary line by driving an earth retaining pile by arranging a cavity part in a foundation part of an existing retaining wall, reinforcing the existing retaining wall by interposing a connecting material between the existing retaining wall and the earth retaining pile, and performing construction work of the new retaining wall after removing the foundation part of the existing retaining wall. SOLUTION: In constructing a new retaining wall 2, an earth retaining pile 7 is driven by arranging a cavity part 6 in a foundation part 1a of an existing retaining wall 1. For example, H shape steel is used as the earth retaining pile 7. The earth retaining pile 7 plays a role to support a rising wall 1b of the existing retaining wall 1, and functions as a reinforcing member of a rising wall 2b of the new retaining wall 2. The existing retaining wall is refinforced by interposing a connecting material 8 between the existing retaining wall 1 and the earth retaining pile 7, and construction work of the new retaining wall 2 is performed after removing the foundation part 1a of the existing retaining wall 1.  Thus, since a method of driving the earth retaining pile in the foundation part of the existing retaining wall is adopted, the new retaining wall can be constructed in a boundary line.

Abstract: PURPOSE:To improve the detection accuracy by forming a protective layer on only a substrate surface part of a depletion layer which is generated on the surface of a diffused resistor, and on the joint surface of the diffused resistor and a semiconductor substrate. CONSTITUTION:A protective film 7 is formed on a substrate surface part of a depletion layer 6 which is generated on the surface of a diffused resistor 5 which has been formed in the vicinity of a supporting part of an Si cantilever 2, and on the joint surface of the resistor 5 and a semiconductor substrate 1. Also, on the surface of the cantilever 2 of the resistor 5, the protective film 7 is not formed, and Si is exposed. Accordingly, a ratio occupied by the resistor 5 being a piezo-resistance can be made smaller enough than a size of the cantilever 2. In the end, the ratio occupied by the protective film 7 for protecting the resistor 5 and the depletion layer 6 becomes smaller enough than an area of the whole cantilever 2. Therefore, thermal stress is scarcely applied to the cantilever 2, and a displacement can be suppressed small. Accordingly, the detection accuracy can be improved.
