Title: Disposal of waste water from waste oil collector
Inventor: HIRAI SADAO
IPC: C02F9/00
Filed: 1979-12-27
Abstract: PURPOSE: To reduce a COD value of waste water discharged from a waste oil collector with a high efficiency, by separating an oily sludge and metals from the waste water, and then decomposing and separating organics from the waste water.  
     CONSTITUTION: An oily sludge is separated from waste water discharged from a waste oil collector, optionally by a process of absorbing the oily sludge with diatomaceous earth. The treated water is then neutraluzed, and metals contained therein are oxidized and separated. Thereafter, organics contained in the water are decomposed and separated from the water, by a proper method, preferably, by a process of decomposing the organics with bacteria, esp. by a process using a rotary plate. Thus the COD reduction rate is remarkably improved, e.g., 90W95%, as compared with a conventional process.

Title: Electromagnetic induction detector
Inventor: TOMITA TOYOFUMI
IPC: G01V3/10
Filed: 1987-07-14
Abstract: PURPOSE:To obtain a detector which is kept low in measuring errors when impulse noise is mixed in without increasing exciting current by providing a rate-of-change limiter on the fore part of a BPF and varying limiting value by means of a phase of an exciting signal from an exciting circuit. CONSTITUTION:An exciting coil 11 is driven by alternating current signals by the use of an exciting circuit 14 and a magnetic flux 13 is generated. A detecting coil 12 detects the magnetic fluxes 13 and electromotive force is generated across it. The electromotive force is amplified by a fore amplifier 15 and input in a rate-of-change limiter 20. The rate-of-change limiter 20 varies limiting value of the rate-of-change by means of a limiting value control signal 24 obtained from the exciting circuit 14, the output 22 is converted into a direct current signal by an AC/DC converter 17 and output from an operation output circuit 18 after the output 22 is passed through a BPF 16 which passes exciting alternating current signal frequency. Therefore, noise is not transmitted to the rate-of-change limiter 20 and excessive measuring errors are prevented from occurring because large signal rate-of-change of the noise exceeds the rate-of-change allowed for the rate-of-change limiter 20 even if the excessive impulse noise is mixed in to electromotive force inducted in a detecting circuit.

Title: Coordinate input device
Inventor: YOSHIMURA YUICHIRO
IPC: G06F3/033
Filed: 1991-07-16
Abstract: PURPOSE:To detect position coordinates with high accuracy by removing distortion caused by interference between plane wave symmetrical waves and plane wave asymmetrical waves from vibration detected after being transmitted by a vibration transmitting body. CONSTITUTION:When a vibration transmitting body 8 is pressed with a vibrating pen 3, the vibration of the pen 3 is detected by sensors 6aa', 6bb' and 6cc' and the coordinates pressed with the pen are decided. In that case, the respective vibration sensors are mounted while facing the sensors 6a and 6a' or the like and detect the vibration on both the faces of the transmitting body 8. The signal detected at the sensors 6a and 6a' is the vibration of overlapping the plane wave asymmetrical waves having the same phase and the plane wave asymmetrical waves shifting the phases at 180 deg.. The both signals are inputted to a differential circuit 12, and the differential signal is inputted to a signal waveform detecting circuit 9. Since the symmetrical wave is cancelled and the asymmetrical wave is double amplified in the differential signal, the accuracy for detecting the vibration can be prevented from being lowered by the distortion of the waveform.

Abstract: PROBLEM TO BE SOLVED: To suppress breakage or deformation of an edge side of a combustion chamber hole in a return part by forming a step on the return part in a laminated metallic plate through coining, and forming a bearing pressure reduction part through coining. SOLUTION: A step 6a to regulate the lamination thickness of a metallic plate laminated on a middle plate 6 is formed on a part where a return part 2a of an outer plate 2 is overlapped, and a stepped bearing pressure reduction part 6b whose thickness is regulated to reduce the bearing pressure distribution, is provided on a hole edge side of the combustion chamber hole at the step 6a. The step 6a and the bearing pressure reduction part 6b are formed through coining. Because the bearing pressure reduction part 6b is formed, the bearing pressure to be exerted on the hole edge side of the combustion chamber hole of the return part 2a of the outer plate 2 under extremely severe condition while an engine is operated, can be reduced. Thus, breakage or deformation of a seal part 8a caused by the repeated large bearing pressure on the hole edge side can be prevented.
