Title: Treatment of organic sewage
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/12
Filed: 1990-07-26
Abstract: PURPOSE:To reduce the generation amount of excessive sludge and to obtain sludge having good dehydration properties by subjecting activated sludge to solid-liquid separation and adding strong alkali to the separated sludge to recycle the sludge to a biological treatment process. CONSTITUTION:Sewage 1 is allowed to flow in an aeration tank 2 of an activated sludge method to be treated in the presence of activated sludge to remove BOD and, when activated sludge is subjected to solid-liquid separation in a sedimentation basin 3, supernatant water 4 and separated sludge 5 are obtained. NaOH 9 is added to the whole or a part 5' of the separated sludge to make the pH of the sludge alkaline and this sludge is stagnated in a stagnation tank 7 for a required time to be supplied to a biological tank 2. The stagnation time of the stagnation tank 7 is predetermined by experiment. A part 5'' of the excessive sludge 5 generated by biological treatment is drawn out to be supplied to a sludge dehydration process or directly drawn out of the biological treatment tank 2 to be supplied to said process 10.

IPC: H05K9/00
Filed: 1988-08-05
Abstract: PURPOSE:To simplify execution working by forming and fixing rear-leg materials comprising the different material from a ferrite molding body at the rear surface of the planar-ferrite molded body. CONSTITUTION:A plurality of rod shaped porcelain rear-leg meatrials 14 each having a rectangular cross section are aligned on the rear surface of a ferrite molded body 12 at a specified interval. The materials 14 are fixed with a bonding agent 16. As the bonding agent 16, an inorganic glass bonding agent is used.

Title: Laminar combustion internal combustion engine
Inventor: ANDO HIROMITSU
IPC: F02M69/00
Filed: 1993-06-04
Abstract: PURPOSE:To enable a tumble flow of rich mixture to be generated in a place close to an ignition plug by letting the engine be equipped with each intake port which is partitioned into a central passage and a side passage by a bulkhead, and concurrently letting the surface of each intake valve faced to the center side passage of each valve stem be one-sided to the center side of each central side passage. CONSTITUTION:In the laminar combustion internal combustion engine, each intake port 46A and 46B which is opened to a combustion chamber 30, and is branched by a branch section 46C, is partitioned into a central passage 4 and a side passage 5 at the outside of the aforesaid passage by each bulkhead 21 extended along each axial center line 1A and 1B. And the valve stems 57 of intake valves opening/closing respective intake openings are disposed in such a way that each center line of the bylkheads 21 and each center line of the valve stems 57 are positioned in a same horizontal plane, and the thickness of each bulkhed 21 is made thinner than the diameter of each valve stem 57. Namely, the surface of each bulkhead 21 at the side of the central passage 4 is one-sided closer to the side passage 25 side rather than the surface of each valve stem 57 at the central passage 4 side. This constitution thereby allows fuel spray to be oriented to an injection plug 11 in the direction P indicated by an arrow head in such a way as to be concentrated to the ignition plug 11.

Title: Automatic focusing system
Inventor: YAMAMOTO MANABU
IPC: H04N5/232
Filed: 1981-12-07
Abstract: PURPOSE:To automatically execute focusing with high accuracy, and also to shorten a focusing time, by freely setting optical path length of a pair of subimage pickup elements for controlling an image forming optical system by a definition detecting system. CONSTITUTION:Definition signals Q, R by subimage pickup elements 31, 41 being at a symmetrical position against a main image pickup element 21 for outputting an image forming definition signal P are processed by a subtractor 54, and movement of a lens 112 is controlled through a composite control signal generator 56, a changeover switch 57, a driving mechanism 61, etc. By this definition detecting system, the element is automatically focused with high accuracy without being influenced by a kind, a position, a contrast, a motion, etc. of an object to be photographed. On the other hand, when most of signals P-R become zero due to large focusing blur, and relation of the signals P-R is different from the reference condition, an output of a logical operation unit 53 is inverted to a low level through comparators 52, 55, and the optical path length of the elements 31, 41 is varied by a search signal generator 58A, and an electromagnetic coil 815, etc. In this way, a difference between the signals Q and R is generated, the lens 112 is not moved to both ends of draw-out and lead-in, and focusing is executed in a short time.

Title: Concentration device of sludge
Inventor: KITSUGI MASANORI
IPC: C02F11/12
Filed: 1983-10-20
Abstract: PURPOSE:To perform concentration of sludge with high efficiency by winding an obstacle comprising a bar-shaped material on a filtration surface. CONSTITUTION:Plural numbers of obstacle comprising square or round bars 8 of 1-6mm. thickness are wound around the internal periphery 1 of a filter cylinder 6 so as to be attached contacting closely to the fitration surface. As the result, the concentrated sludge accumulated on the inside of the filtration surface gets over the bar-shaped member 8 and scraped off always and is upset. Thus, the dehydrated concentrated sludge on the fitration surface is crumbled and forms passage of water. Therefore, the dehydration is performed effectively without causing clogging. By this method, effective concentration is performed without reducing concentration efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide a thermal head controller for producing a stamp print face in which clogging with a bubble is prevented from being generated while exceeding over a range required for a stamp print face and thin lines in a print is prevented from disappearing. SOLUTION: A CPU 1 (central processing unit) reads out a print data stored at a memory section 2. The memory section 2 stores a data to be printed on a stamp print face transferred from a host computer (not shown). The CPU 1 transfers a print data being read out to an operating section 3 performing print pattern processing. The operating section 3 reads the pattern data into its own shift register and performs print pattern processing. The print pattern processing is performed in order to prevent a fine character from disappearing due to thermal deformation of a polyethylene foamed sheet at the time of forming a stamp print face. More specifically, the CPU 1 operates, at the operating section 3 thereof, the heating energy of a heating element in a thermal head 5 based on the printing and nonprinting conditions of adjacent dots and the temperature of the thermal head.
