Title: Method for concentrating and dehydratig organic sludge
Inventor: KATAOKA KATSUYUKI
IPC: C02F11/12
Filed: 1980-10-22
Abstract: PURPOSE: To concentrate and dehydrate an organic sludge at low cost while saving energy and space by a method wherein an iron based flocculant and either H 2 O 2  or O 3  are added to the organic sludge, then an alkali agent and a high polymer fluocculant are added, and the sludge is dehydrated by gravity on a porous water- permeable body, followed by mechanical dehydration.  
     CONSTITUTION: An iron-based flocculant 2, such as FeSO 4 , and H 2 O 2  or ozone 3 are added and mixed into the organic sludge 1 such as an activated sludge or a residual sludge in an agitating tank 4. After adjusting the pH of the sludge by adding an alkali agent 6 in a neutralizing tank 5, a nonionic or anionic high polymer flocculant 8 is added to the sludge in a flocculating tank 7 so as to form course  flocs. The flocs are fed onto the porous water-permeable body such as a screen 9 or  a filter cloth to separate the sludge into concentration-derived water 10 and a concentrated sludge 11. The sludge 11 is dehydrated by a filter press 12 without using any chemical, and the sludge 11 is separated into a dehydrated cake 13 and a dehydration filtrate 14. The concentration-derived water 10 and the filtrate 14 are disposed in a suitable manner.

Title: Data processor
Inventor: SATOU MASAYUKI
IPC: G06F3/00
Filed: 1977-12-10
Abstract: PURPOSE: To utilize the bus construction logically in multiplicity, which is physically limited, by adopting the multi value logic circuit to the bus line for data delivery.  
     CONSTITUTION: When two value digital information is parallely inputted to the input terminals 51 and 5b of the mixer (multi-value logic circuit) 5, the multi signal is transferred to the slicer (multi logic circuit) 6 through the bus line 4. The slicer converts the multi-value signal again into the binary digital information, that is, input and outputs it to the terminals 6a and 6b. Thus, the number of bus lines can logically extended and the through-put time of the entire system can be increased.

Title: Gas detecting element and its manufacture
Inventor: YODOGAWA MASATADA
IPC: G01N27/12
Filed: 1987-06-15
Abstract: PURPOSE:To quicken response, to preclude an electrode short circuit, and to improve sensitivity and reliability by forming a groove in a sensor base between a couple of electrode. CONSTITUTION:A conductive film 9 is formed on one or both surfaces of the sensor base 5 entirely and irradiated with a laser light beam 10 from above. the beam 10 is moved relatively to the base 5 so as to obtain the pattern of the electrodes 6 and 7 and groove 8. Then the conductive films 9 is separated along the groove 8 simultaneously with the formation of the groove 8 to form the electrodes 6 and 7. Then the cutting surface of the base 5 is reduced with laser working heat, so a heat treatment is carried out thereafter to oxidize the part reduced by laser working again, thereby obtaining a semiconductor. At this time, the area where gas operates is increased because of the groove 8, so the sensitivity is increased. Further, an electric insulating gap is formed between electrode branches 61 and 71 of the electrodes 6 and 7 by the groove 8, so the electrodes are prevented from short-circuiting and the reliability is improved.

Title: Bearing device of rotating electric machine
Inventor: TANAKA MASATAKA
IPC: H02K5/10
Filed: 1993-06-21
Abstract: PURPOSE:To prevent the base oil of a grease from leaking out to the outside, by providing an air vent hole in a grease exhausting pipe, and by making the gap between an oil thrower and a cover have a labyrinth structure. CONSTITUTION:When a new grease is squeezed into the inner part of a bearing 2 from a nipple 8 through a grease injecting pipe 7, a waste grease and a base oil which oozes from the grease by the heat generation of the bearing 2 are blown off to a grease exhausting pipe 10 by virtue of the centrifugal action caused by the rotation of an oil thrower 5. Concurrently, the air flow generated by the rotation of the oil thrower 5 proceeds to the grease exhausting pipe 10 owing to the air resistance caused by the labyrinth structure of the end of a cover 6 and owing to the air vent hole of the grease exhausting pipe 10. Thereby, through the drawing action caused by this air flow, the base oil is gathered in the grease exhausting pipe 10. Therefore, only a small quantity of base oil flows out to the outside, and the environmental pollution of the base oil of the grease can be reduced.

Title: Intake device of internal-combustion engine
Inventor: KAMIMARU SHINJI
IPC: F02M13/02
Filed: 1984-07-17
Abstract: PURPOSE:To form a swirl and obtain intake efficiency suitable for the operating condition of an engine, by providing two separate intake pipes in one cylinder and arranging in the vicinity of each port an opening and closing valve interlocking to a throttle valve further providing a communication passage from the upstream of the opening and closing valve in one side to the downstream of the opening and closing valve in the other side. CONSTITUTION:An engine, having two intake ports 3, 4 in a cylinder head 1 and a separate intake pipe 10, 11 in each port, provides a primary side throttle valve 13 and a secondary side throttle valve 16 of a carburetor 12 in each intake pipe 10, 11 while a control valve 7, 8 interlocking to each throttle valve in the vicinity of the intake port 3, 4. The engine, having a communication path 9 between the intake ports 3, 4, allows air to flow from the communication path 9 toward the port 4, generating a strong swirl in a cylinder because the control valves 7, 8 are almost fully closed when the primary throttle valve 13 is in a small opening. The engine, in which as the control valve 7 opens an air quantity in the port 3 increases, weakens the swirl more improving intake efficiency by removing the swirl if the control valve 8 is also opened.

Title: Automatic distortion compensator
Inventor: ONODA MASAHIRO
IPC: H03G1/04
Filed: 1990-06-07
Abstract: PURPOSE:To attain the accurate automatic distortion compensation control without using a band blocking filter with sharp characteristic by synthesizing the output signal of a compensated amplifier and the input signal of a distortion compensator in the phases reverse to each other and in the equal amplitude for suppression of the signal component and then detecting a distortion component out of the synthetic signal. CONSTITUTION:An input signal is inputted to a compensated amplifier 2 via a distortion compensator 1, and the output signal of theamplifier 2 including a distortion component is outputted. Meanwhile both input and output signals are partly inputted to a distortion detector 3 as the input signals IN1 and IN2. Then both signals IN1 and IN2 are synthesized together in the phases reverse to each other and in the equal amplitude in regard to the signal component. Then the high and low distortion components VH and VL contained in the output signal and a remaining signal component VF are applied to a control circuit 4. Thus the circuit 4 controls the compensator 1 based on the component VH and VL and at the same time produces the control signals CONT1 and CONT2 to apply then to the detector 3. Then a distortion compensation component is produced from the compensator 1 and superposed on the input signal of the amplifier 2.
