Title: Process and apparatus for separating precipitate in activated sludge treatment
Inventor: NIWA CHIAKI
IPC: B01D21/08
Filed: 1983-12-14
Abstract: PURPOSE:To maintain the quality of treated water at satisfactory level by extracting specified amt. of sludge from a precipitation tank depending on a detected signal of anaerobic state of a sludge layer in the precipitation tank and returning the sludge to the precipitation tank. CONSTITUTION:An oxidation reduction potential sensing element 25 is provided to near the bottom of a precipitation tank 10 as a means for sensing that the inside of a sludge layer 3 of the precipitation tank 10 has changed to anaerobic state. And the flow rate of the sludge is performed by inputting the data concerning the oxidation- reduction potential in the sludge layer 3 into a controlling device 27 and adjusting the degree of opening of an electromotive valve 17 of a sludge transfer pipe 16 and an electromotive valve 21 of a return pipe 22 in accordance with the inputted signal. In this stage of separating precipitate, the settled sludge inside of the precipitation tank 10 is held at slowly moving condition in the inside of the sludge layer 3. Therefore, the anaerobic part in the inside of the sludge layer 3 is removed and denitrification reaction is retarded, moreover, formation of scum is prevented due to acceleration of defoaming. By this process, the quality of treated water is held at satisfactory level without causing mixing of sludge in the supernatant water.

Title: Controller for dc motor
Inventor: YOSHIKAWA YOSHIRO
IPC: H02P7/29
Filed: 1985-10-23
Abstract: PURPOSE:To inhibit the heat generation of a transistor operating on overvoltage or overcurrents by comparing voltage applied to a DC motor and currents flowing through the DC motor and conducting protection operation. CONSTITUTION:A transistor 8 is ON-OFF controlled by an output from a signal generating circuit 16. When the detecting value of a current detector 6 reaches a specified value or more, the transistor 8 is brought to an OFF state. Output voltage from the current detector 6 drops with the discharge of the charges of a capacitor 12, but the reference voltage of a reference-voltage generating circuit 13 also lowers simultaneously, thus leaving the transistor 8 as it keeps an OFF state. When the voltage of the capacitor 12 drops and the minimum supply voltage of a comparator 3 cannot be maintained, transistors for a single- phase bridge circuit 5 are all turned OFF. Accordingly, reference voltage is made higher than output voltage from the current detector 6, thus bringing the transistor 8 to an ON state.

Title: Countercurrent scavenging steam transmission method
Inventor: DOUEIN TEII FURIISEN
IPC: B01D61/36
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To increase an average transmission flow rate without requiring high vacuum and to keep the temp. of a supply stream high by supplying the sweep steam of condensible vapor to the supply side of a membrane and collecting a mixture on a transmission side of condensible vapor and a transferred component before separating the transferred component. SOLUTION: A supply stream 10 containing at least two kinds of vapor components A, B is supplied to a membrane module 25 while a condensible vapor sweep stream 32 is supplied to the transmission side of the membrane module 25. The component A of the supply stream is removed by the membrane module 25 to form a holding stream 14 reduced in the amt. of the component A. Since the condensible vapor sweep stream 32 passes through the membrane of the module 25, it is mixed with the vapor transmitted matter of the component A to form a transmission side mixture 34 which is, in turn, discharged from a vapor outlet opening provided in the vicinity of the supply end of the module 25. By this constitution, the flow rate of a transmitted stream is increased by the increase of propelling force.

Title: Biaxially oriented thermoplastic resin film
Inventor: ABE KOICHI
IPC: B29K105/16
Filed: 1989-09-14
Abstract: PURPOSE:To enhance scratch resistance, by providing a film with such a surface that at least a specified number of protrusions formed by inactive particles are disposed in series over a length of at least a specified number times the diameter of one protrusion. CONSTITUTION:A biaxially oriented thermoplastic resin film comprises a film containing a thermoplastic resin A and inactive particles as main constituents and laminated by co-extrusion with a film containing a thermoplastic resin B as a main constituent, wherein at least 50% of protrusions formed on a film surface by the inactive particles are disposed in series over a length of at least 10 times the diameter of one such protrusion. The direction of the series of the protrusions preferably coincides with the longitudinal direction of the film, whereby the protrusions themselves are strengthened structurally. The pressure exerted per protrusion when a roll makes contact with the film surface is lowered, and the film surface is less susceptible to shaving, so that scratch resistance is enhanced. The protrusions are disposed in series over the length of at least 10 times the diameter of one protrusion, which ensures a conspicuous improving effect on scratch resistance. When the length is smaller, a large effect cannot be expected because the surface condition is little different from that in the case of substantially uniform dispersion of the protrusions.

Abstract: PURPOSE:To obtain an ideal room temperature distribution at the time of space cooling and heating operations and prevent unpleasant noise at the time of switching air outlets by providing an upper and a lower air delivery fans comprising independent cross-flow fans, and erecting a heat-insulated partition in the center of a bow-figured heat exchanger. CONSTITUTION:At the time of starting a cooling operation, both the upper and lower air delivery fans 11, 12 are operated to deliver cool air from upper and lower air outlets 15, 18, and, once the room temperature stabilizes at a certain level, only the upper air delivery fan 11 is operated. If the cooling demand is not as great from the onset, only the upper air delivery fan 11 is operated. For heating operations, only the lower air delivery fan 12 is operated, similar to the cooling operations, once the room temperature stabilizes at a certain level, and, if the heating demand is not as great from the onset, only the lower air delivery fan 12 is operated. Since the air is rapidly cooled or heated at the time of cooling or heating operation, followed by the cooling or heating at an appropriate air blowing rate, an ideal room temperature distribution can be obtained, and unpleasant noise can be prevented at the time of switching the air outlets.
