Title: Method for operating water treating apparatus having membrane separator
Inventor: IZUMI SEIJI
IPC: C02F3/12
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of an aerator and the fatigue rupture of filtration membranes at the time of operating a water treating apparatus having a membrane separator. SOLUTION: When the liquid level of an activated sludge mixed liquid 14 falls to a prescribed lower limit water level LL, the permeated water 28 lead out through a permeated water leading out system 8 is filled into an aerator 20 by a return pipe 26 disposed in communication with the aerator 20 and is returned into a vessel. When the liquid level of the activated sludge mixed liquid 14 rises to a prescribed upper water level HL thereafter, the filling of the permeated water 28 is stopped. As a result, the aeration 20 14 is eventually washed by the permeated water 28 every time the activated sludge mixed liquid 14 falls down to the lower limit water level LL and, therefore, the clogging of the aerator 20 and the deposition on the membrane surfaces of membrane separators may be prevented.

Title: Component arrangement position determination system
Inventor: IWASE MASAKAZU
IPC: H05K3/00
Filed: 1989-10-04
Abstract: PURPOSE:To determine the best arrangement position by determining a virtual arrangement position for a component whose arrangement position is not determined and determining the arrangement positions of components in consideration of it. CONSTITUTION:The connection component virtual arrangement position determi nation part 7 of an arrangement position determining mechanism 4 determines nearly the center of a group that the component which is to be connected to a component fixed in arrangement position and does not have its arrangement position fixed as the virtual arrangement position of the component. Further, an evaluation calculation part 8 for arrangement position determination calculates the strength of connection between the component whose arrangement position is to be determined and another component in connection relation with the component. An arrangement position determination part 9 determines the optimum arrangement position of the component whose arrangement position is to be determined from the connection strength (evaluated value). Consequently, the optimum arrangement position of the connection whose arrangement position is not determined is determined in consideration of the component arrangement position.

Title: Logical testing circuit for integrated circuit
Inventor: KAWASAKI SOICHI
IPC: G01R31/28
Filed: 1988-10-14
Abstract: PURPOSE:To shorten an input signal sequence by dividing input/output buses into an input part and an output part, executing separately a logical test with respect to a pre-stage circuit and a post-stage circuit of the bus, so that an input signal sequence and a random number signal sequence generated by a computer can be applied. CONSTITUTION:At the time of a logical test (at the time of T1=1 and T2=1 of test signals), a high impedance (HI) processing use buffer 4A5 is set to a logical data output state by T1=1, and a Q output of an FF 63 in an HI processing circuit 6 is sent out to an internal output bus 1A. However, when all of bus output buffers 4A1-4A4 become an HI state, that is, when one of LSI internal signals SE1-SE4 becomes '0', said Q output is outputted. Pulse width of its Q output is a one-period portion of a clock pulse phi1, therefore, it can be discriminated from LSI internal signals SA1-SA4 having pulse width of a 2-period portion. Internal input buses IB-1D, 3B-3D are also operated in the same way. A logical signal outputted to buses 1A-1D is inputted to a storage circuit 8, compressed by synchronizing with phi1 and outputted to an output terminal 10 through an output buffer 9.

Filed: 1988-10-14
Abstract: PURPOSE:To make it possible to increase absolute precision in measurement by utilizing the frequency of a carrier wave of an accurate signal source and by calibrating the degree of modulation therewith. CONSTITUTION:First a signal inputted to an FM detection circuit 2 to be tested is made to be a non-modulated signal and the frequency of this signal is set at the time of a peak obtained by adding an FM frequency deviation from the central frequency f0. At that time, a first DC voltage outputted from the output end of the circuit 2 is measured. Next, the frequency of the input signal is set at the time of a bottom. At that time, a second DC voltage outputted from the output end of the circuit 2 is measured and a difference between the first and second DC voltages is determined. A detection output level is detected from this difference voltage. Next, the signal inputted to the circuit 2 is made to be an FM modulation signal and an AC voltage outputted from the circuit 2 is measured by an AC voltmeter 3. The degree of modulation of an FM modulation signal source is adjusted so that a value obtained by this measurement be the same with the detection output level determined from the difference voltage. With the adjusted degree of modulation maintained, thereafter, detection output characteristics such as a frequency characteristic and a distortion factor are measured.
