Title: Prediction of ph level of mixed water in mixing pond
Inventor: IKEGUCHI TAKASHI
IPC: B01D21/01
Filed: 1978-03-31
Abstract: PURPOSE: To maintain the pH level of mixed water in a mixing pond around 7, by predicting the pH level in consideration of the ratio of transfer to the air of CO 2  produced by the supply of a coagulant to a water purification plant or the like and controlling the supply of the coagulant and alkali.  
     CONSTITUTION: The temperature, alkalinity and pH level of raw water not yet supplied with the coagulant 10 are measured. The pH level of the mixed water is measured by a pH meter 6 provided between the mixing pond 7 and a flock making pond 8. A calculator 5 calculates the dissociation constant of the raw water from its temperature. The initial CO 2  concentration is calculated from the dissociation constant, the alkalinity and the pH level of the raw water. The transfer ratio of the CO 2  is calculated from the pH level of the mixed water at the present, the time of residence at the pH meters 3, 6, the alkalinity and pH level of the raw water, the temperature of the mixed water and the ratio of supply of the coagulant. The pH level of the mixed water is accurately predicted from the dissociation constant, the initial CO 2  concentration, the CO 2  transfer ratio, the raw water alkalinity and  the coagulant supply ratio. This makes it possible to take preventive measures to stabilize the quality of the water.

Title: Spurious component reducing circuit
Inventor: NAKANO YOSHIAKI
IPC: H03H5/02
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To enable a spurious component reducing circuit to effectively suppress the radiation and mixture of a spurious component, without losing a main signal. SOLUTION: A series circuit composed of a resistance R and an LC parallel circuit 2, having parallel resonance at a main signal frequency fr, is connected to a main signal line 1 in parallel and an LC series circuit 3 which has series resonance at a spurious frequency fs is connected with respect to the LC parallel circuit 2 in parallel. High impedance is obtained at a point (b) to a main signal fr through the parallel resonance of the LC parallel circuit 2, so the resistance R becomes invisible from a point (a), and so that no influence is exerted on the main signal line 1. As for signal components of other frequency, the impedance at the point (b) decreases, so the signals are attenuated by the resistance R when passing the point (a).  The point (b) is equivalently grounded, specially with respect to a spurious frequency fs through the series resonance of the LC series circuit 3, so that spurious components passing the point (a) are fully attenuated by the resistance R.

Title: Charging method for battery
Inventor: TAMAI MIKITAKA
IPC: H02J7/02
Filed: 1993-02-25
Abstract: PURPOSE:To prevent the deterioration in batteries when a plurality of batteries are connected in series and charged, by providing uniform voltages in a balanced charging and discharging way, in which a low-voltage battery is charged, while a high-voltage battery is discharged to diminish the difference between battery voltages. CONSTITUTION:A battery pack 6 made up of a plurality of batteries connected in series is charged by a DC power supply 1 through a charging circuit 2. When a microcomputer 6 detects a fully charged state, a switch SWm is opened. The microcomputer 5 monitors the voltage of each battery (A) or (B), and when a voltage of the battery (A) or (B) is over a given level, a switch 8A or 8B is turned off to discharge the battery (A) or (B) through a resistor 7A or 7B. In this case, the overvoltage battery (A) or (B) may be stopped from charging for a while and the lower-voltage battery may be only charged. Then, each battery in the battery pack 6 has a uniform voltage charged or discharged in a balanced way, and this balanced charging is preferably carried out before a fully charged state. Consequently, a cyclic life is increased so that the battery has a longer life.

Title: Method and device for treating waste water
Inventor: KONO SHUHEI
IPC: C02F3/00
Filed: 1991-03-04
Abstract: PURPOSE:To efficiently reduce BOD and nitrogen concn. in a finally treated water by a method wherein waste water is treated in anaerobic and aerobic treating chambers and the water residence time in the anaerobic treating chamber is set at 3-8 hours in a waste water treating process for circulating a part of aerobic treating water. CONSTITUTION:The total digestion rate beta is obtained by extrapolating the minimum nitrogen removal rate alpha of a purifying tank devoid of a partial circulation process from the removal rate in a waste water treating device having a circulating process. The total digestion rate betabecomes greater with the decreasing concn. gamma of decomposable total organic carbon(TOC) at the exit of the anaerobic treating chamber and that become almost equal to each other within certain values. Accordingly, the total digestion rate alpha of the device and the decomposable TOC concn. gamma are required to be within a desirable range not exceeding the certain values. From the relationship between the decomposable TOC concn. gamma and the residence time T of the waste water in the anaerobic treating chamber, the residence time of about 3-8 hours within the range not exceeding the certain values of the decomposable TOC concn. gamma is obtained. Although the residence time T in the anaerobic treating chamber is related to the amt. of inflow waste water, the cirulation water amount and the effective volume, the circulation water amount is obtained by substituting the residence time T and the amt. of the water discharged and the decomposable TOC concn. gamma is reduced effectively.

Abstract: PURPOSE: To provide a landing gear of little air resistance and small occupied space by reciprocating a sliding type door body along a pair of L-shape guides between the inside and surface of a vehicle to close a doorway in a landing gear chamber door for closing the doorway of the landing gear, free to go in and out, of levitating type rolling stock or the like. CONSTITUTION: When a fluid pressure cylinder 40 is put in elongating motion from the contracted state, a rotating lever 30 gets close to the vertical state from the horizontal state along a lateral plate 13, and a roller 23 moves toward a doorway 8 while moving in a guide groove 32 from the base end side toward the tip side. A divided piece 21 in a lowest stage thereby moves between the horizontal parts of L-shape guides 12, 12 from the inner part toward the doorway 8. As a result, a door body 20 passes while bending between the bent parts from between the horizontal parts of the L-shape guides 12 and enters between the vertical parts so as to close the doorway 8. When the fluid pressure cylinder 40 is contracted, the rotating lever 30 is placed in the horizontal state along the lateral plate 13 so as to open the doorway 8 and to allow a guide wheel 2 to be protruded outside.

Filed: 1990-02-19
Abstract: PURPOSE:To prevent any vibration during traveling of a vehicle by providing a suction port from a plunger chamber toward the outer periphery of a rotor, and disposing a rotary valve for opening and closing the suction port in association with a cam for driving the plunger. CONSTITUTION:In the absence of a rotational difference between a cam 1 and a rotor 4, a torque is not transmitted because a plunger 6 is not operated. With the rotational difference between the cam 1 and the rotor 4, the plunger 6 in a discharge stroke is pushed in the axial direction by the cam face of the cam 1. The plunger 6 dischargeds oil in a plunger chamber 5 into a high pressure chamber 16 through a discharge hole 36 and a discharge valve 37, and concurrently a suction chamber 34 is forcibly closed by a rotary valve 31. The oil discharged into the high pressure chamber 16 is supplied to a low pressure chamber 20. At this time, an increase in each oil pressure in the chambers 16, 5 by resistance of an orifice 18 generates a reaction force in the plunger 6. The cam 1 is rotated against the reaction force to generate a torque, which is transmitted between the cam 1 and the rotor 4.

The material of this tape 10 has a heat resistance higher than molding temperature and less friction to the matter to be molded, and further the thickness and width of the tape are adequately set according to the product size. By virtue of the tape 10, at least the thickness for that of the tape is ensured for the product to be molded, and the deviation in the width direction of the product to be molded is prevented by the tape functioning as a chock, so that the uniformity in the width direction and thickness direction is obtained.
