CONSTITUTION:This range finder consists of the AFIC 6 for automatic focusing, a position detecting element 3, an infrared-ray emitting diode 1, a light emitting diode driving circuit 2, a CPU 20, and a lens driving circuit 18 and the AFIC 6 consists of a photodetection signal processing circuit 7, a differential amplifier 8 for an AF signal, a clamp level setting circuit 9, a 2-bit clamp level specifying circuit 21, and a clamp level storage circuit 22. In this case, the reflected light of light projected on a subject from a light emitting element for range finding is photodetected by a photodetecting element. Further, a 1st and a 2nd photodetection current generated by the photodetecting element are inputted to the differential arithmetic circuit 8. This distance signal is corrected with the correction data regenerated by the correction data storage circuit 22 and focusing control over a lens is performed by the control circuit 20 with a corrected distance signal outputted from the difference arithmetic circuit 8.

Title: Trench device by capillary seepage having denitrification function
Inventor: NIIMI TADASHI
IPC: C02F3/34
Filed: 1981-05-22
Abstract: PURPOSE: To discharge the total nitrogen amt. in sewage in a pollution-free state effectively and inexpensively by packing the soil which contains carbon source materials and in which briquette structure is developed in an impervious tank and the parts from this up to a seepage device.  
     CONSTITUTION: When sewage is flowed in a discharge pipe 6, the sewage leaches into packings 8, seeps into soil 12 through aluminum 9 and is once stored in a lower impervious tank 10. While the sewage seeps from the seepage device in the upper part down into the tank 10 in the lower part, denitrifying bacteria are propagated by carbon sources 11 with these as nutrient sources. On the other hand, since the amt. of the sewage supplied from the pipe 6 fluctuates usually, the sewage level 13 in the tank 10 fluctuates vertically in accordance with this. If the water levle is high, the denitrifying bacteria are easier to act and if it is low, the nitrifying bacteria are easier to act. As these act altrnately, the denitrification is accelerated.

Title: Lightening resistive horn insulator device
Inventor: NAKAYAMA TETSUYA
IPC: H01T4/14
Filed: 1988-03-30
Abstract: PURPOSE:To aim at stabilization of the pole-like installation state and discharge characteristics of a lightening arresting insulator by aligning the turningly moving axial line of a hanging metal device and the central axial line of the lightening arresting insulator with a common vertical plane. CONSTITUTION:While a lightening arresting insulator 16 is in static state, the turningly moving axial line of a hanging metal device 4 and the central axial line of the lightening arresting insulator 16 are aligned in the same vertical plane so that the pole-like installation state of the insulator becomes stabilized. In addition, even if a power line is swung due to wind pressure or the like and a supporting insulator is also swung in an arbitrary direction, the hanging metallic device 4 and lightening arresting insulator 16 are put turning movement in the same direction, thereby not only preventing a big inertia force from working upon the lightening arresting insulator 16 so that strength of a fitting 2 and the hanging metal device 4 can be lowered but also keeping constant the interstitial length for discharge by properly constructing arcing horns both at voltage application side and installation side. With this procedure it is possible not only to support steadily the lightening arresting insulator 16 but also to widen its usage regardless of work condition.
