Title: Apparatus for forcibly deteriorating oil
Inventor: FUJIWARA HIDEYUKI
IPC: G01N33/28
Filed: 1990-04-27
Abstract: PURPOSE:To enhance the oil oxidation ratio to the supply amount of gas and to promote the deterioration of oil by performing control so that the valve arranged on the way of the gas (oxygen or air) supply pipe to an oil container is opened and closed corresponding to the internal pressure of the oil container. CONSTITUTION:A control part 2 has a gas supply control means controlling the opening and closing of a valve 16 on the basis of the detection value of a pressure sensor 17. When the oil (e.g., gasoline) 6 in a hermetically closed oil container 5 is oxidized by the gas in the container 5 and the pressure in the container 5 lowers to a lower limit set value, the valve 16 is opened to supply the gas into the container 5 from a supply source 14. Subsequently, when the pressure in the container 5 rises to an upper limit set value, the valve 16 is closed to stop the supply of the gas. When the oil is oxidized by the supplied gas and the pressure in the container 5 lowers to the lower limit set value, the above mentioned operation is repeated. Therefore, all of the gas supplied to the container 5 is consumed in the oxidation of the oil 6 and the oil 6 can be rapidly deteriorated. Since the oil 6 is not discharged to the atmosphere, no environmental pollution is generated.

IPC: H01P1/20
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of a branching filter while suppressing an unnecessary wave by composing only an output-terminal side resonator of a dielectric resonator with low capacity Q like a coaxial resonator. SOLUTION: This branching filter uses a semicoaxial dielectric filter in asymmetrical structure which has three dielectric resonators 11 arranged in its case 10 and includes a coaxial resonator 15 as only an output-side resonator exerting small influence on its loss. The coaxial resonator 15 is arranged only on the output terminal side of the dielectric filter and a disk type dielectric resonator 11 which has high Q of a branching filter circuit is used as the input- terminal side resonator of an initial-stage dielectric filter affecting at least the loss of the branching filter, so while an unnecessary wave is reduced, the out-band reflection loss is made small to prevent the circuit loss of the branching filter from increasing.

Filed: 1989-05-08
Abstract: PURPOSE:To prevent an increase in required power by allowing a liq. mixture contg. flocs treated by a biological treating tank to flow in an inclined pipe to separate solid and liq. CONSTITUTION:Solid matter is separated from raw org. sewage by a sand removing device 1 and a screen 2, and the sewage is introduced into a bioreactor 3 from an inflow pipe 4.

Abstract: PROBLEM TO BE SOLVED: To precisely detect the position and the area of a vehicle by a processing approximated to the sense of a human by three-dimensionally sensing a road environment for a wide range through the use of a stereo image processing and transforming measured three-dimensional data. SOLUTION: Image pickup devices 1 end 2 image-pick up a road face and the vehicle on the road environment. A left image 3 in the right and left images 8 and 4 is set to be a reference image. A correspondence part 6 divides the left image 3 into blocks in horizontal and vertical directions. Similar areas are detected from the right image 4 at every block and a parallax is obtained. A plane estimation part 7 three-dimensionally estimates the position on the road face by Hough transformation by using the parallax at every block, which is outputted from the correspondence part 6. A distance measurement part 8 transforms the parallax into distances from the image pickup devices 1 and 2 to the vehicle and the road face by using the parallax.  A vehicle detection part 9 estimates three-dimensional data where the vehicle exists at every block and it is compared with three-dimensional data on the road face and a vehicle detection image 10 is obtained.

Filed: 1980-08-18
Abstract: PURPOSE:To reduce spurious response at 3f0 (center frequency) and to extend the blocking region, by providing at least one 60 deg. coupling section with a line of a coupling section of a paralel coupling filter using a TEM line resonator. CONSTITUTION:Electrical lengths theta01-theta34 of coupling sections are selected as theta01=theta34=90 deg., theta12=theta23=60 deg. at center frequency f0 and input/output lines 81, 82 and resonators 83-85 of lambdag/2 of both end open type as a TEM line resonator constitute the coupling sections. Since the resonators 83-85 are of lambdag/2 type, spurious resonance is caused at nf0(n=1,2,3) and since the coupling electric length is 90 deg. for the coupling lengths theta01, theta34, no coupling is produced at 2f0, 4f0, 6f0 and also no coupling is caused at 3f0, 6f0, 9f0 since the coupling electric length for theta12, theta23 is 60 deg.. Thus, in the response of this filter, the spurious response at 2f0, 3f0. 4f0 can be reduced.

Title: Servo-controlling device
Inventor: SAKANO TETSUROU
IPC: G05B19/19
Filed: 1983-06-24
Abstract: PURPOSE:To effectively prevent hunting without lowering the response characteristic and controlling accuracy, by changing a loop gain in accordance with the presence/absence of the change in commanded position and the scale of positional errors. CONSTITUTION:A microprocessor 1 finds a positional error signal E=Pc-Pd from a commanded position signal Pc and detected position signal Pd and, when the absolute value of the error signal E is larger than the 1st level Eh, switches the gains of amplifiers 2 and 4 to larger values Kph and Kvh. When the absolute value is smaller than the 2nd level E, the microporcessor 1 sets the gains of the amplifiers 2 and 4 to smaller values Kpl and Kvl. After the gains of the amplifiers 2 and 4 are set in this manner, the value of the commanded position signal Pc is updated, a speed command signal Vc is calculated, and then, a signal W=Kv(Vc-Vd) proportional to a speed error signal (Vc-Vd) is calculated from a detected speed signal Vd. Then a proportional and integration compensations are performed on the signal W and the compensated signal is fed back to a servo loop through a tacho-generator 10 and pulse coder 11.
