IPC: G01C21/24
Filed: 1990-05-31
Abstract: PURPOSE:To reduce computation significantly by using a relative position speed from a reference orbit of an outer space craft as state variable while a deviation of a distance.distance rate of change between an artificial satellite for supporting navigation and the outer space craft from a reference distance.distance rate of change of a measured value is used as observation value. CONSTITUTION:A dedicated receiver 4 receives a signal 8 transmitted from an artificial satellite 6 for supporting navigation on an orbit encircling the earth to read information for calculating an absolute position.speed 7 xs of the satellite 6contained in the signal while obtaining a measured value 9z of a distance.distance rate of change between the satellite 6 for supporting navigation and the outer space craft 2 to send information obtained to a navigation computing device 5, which calculates an absolute position.speed xs7 of the satellite 6 based on the information from the receiver 4.

Title: Sputtering target
Inventor: FUJITA YOSUKE
IPC: C23C14/34
Filed: 1986-06-18
Abstract: PURPOSE:To form a thin film having decreased defects on a substrate to be treated without inducing the dielectric breakdown of the thin film deposited in non-etching regions by using an insulating material to form at least part of the non-etching regions of a sputtering target. CONSTITUTION:After the inside of a vacuum vessel 6 is evacuated, Ar and O2 are supplied at 4:1 ratio and the substrate 7 to be treated is preheated at 150 deg.. The target is made of an SiO2 insulating material in the central part 1 and outside peripheral part 3 and is disposed with a doughnut-shaped Ta plate 2 in the intermediate part thereof. Such target 10 is placed on a backing plate 4 and a permanent magnet 5 is disposed in the lower part thereof as a cathode. Sputtering is executed by impressing a negative high voltage thereto from a DC power source 8 to form a thin film of Ta2O5 on the substrate 7. The non-etching regions 1, 3 of the target are formed of the SiO2; therefore, even if the thin film of the Ta2O5 is formed therein, the dielectric breakdown in said regions does not arise at all. The splashing and sticking of part of the melt of the target onto the thin Ta2O5 on the surface of the substrate 7 and the consequent deterioration in the material quality of the thin Ta2O5 film are thus prevented.

Filed: 1994-06-01
Abstract: PURPOSE:To provide a recognizing method for a character capable of accurately recognizing the character even when dust and stains are present at the time of reading the character by a machine such as an OCR or the like. CONSTITUTION:Patterns 2 for recognition formed by arranging square black areas with an equal interval in the direction of the side for which the size of the equal interval is changed corresponding to the character are written with the characters 1.

Title: Automatic gap adjusting device for disc brake comprising parking brake
Inventor: IKEGAMI HIROSHI
IPC: F16D65/14
Filed: 1987-06-09
Abstract: PURPOSE:To manufacture the captioned device at low cost by screwing a sleeve nut on an one-way reversible nut reversible toward the expanding direction of a locked rod so as to constitute a length adjusting mechanism. CONSTITUTION:When a false brake gap is generated by deformation of the brake constituting members due to an excessive fluid pressure caused by quick braking or the like, a small piston 76, which is fixed in a movable sliding manner, into a counter boring of a rod 60 equipped with an enlarged head portion 77 engaged with the frontal concaved portion 79 of the flange 70 of a sleeve nut 69, is pushed back by the pressure fluid. A brake drag is prevented by not having the rod 60 and the sleeve nut 69 making an excessive adjustment of a length adjusting mechanism but leaving the false brake gap caused by the deformation of the brake constituting member as it is while the pushing power hinders the sleeve nut 69 to move forward by being pushed with a compressed coil spring 73. Owing to this constitution, the structure can be made simple and portions requiring an precise finishing are only the circumference surface of the small piston 76 and the inner circumference surface of the rod 60 where it slides along the circumference surface of the small piston 76, which all contribute to a low manufacturing cost.

Title: Oxygen sensor for internal combustion engine
Inventor: ISHITANI MASAO
IPC: G01N27/419
Filed: 1986-06-20
Abstract: PURPOSE:To reduce a voltage applied to an oxygen pump part while enabling oxygen concentration to be detected by arranging end parts of a couple of measurement electrodes on an insulation member in a hollow part. CONSTITUTION:The hollow part 14 is formed of a substrate 11 and a stabilized zirconia plate 12 inside the abutting part B at the tip side of an insulation substrate 11. The couple of measurement electrodes 15 and 16 are provided successively while passing through the substrate 11 and an oxygen concentration detection part 17 is formed at the tip parts of the electrodes 15 and 16. Further, pump electrodes 18 and 19 are provided on the internal and external surfaces of the plate 12 above the detection part 17 to form the oxygen pump part 20. A fine gap A for admitting exhaust gas into the hollow part 14 is formed at the contacting part B between the substrate 11 and plate 12 by polishing. Thus, the gap A for admitting the exhaust into the hollow part 4 is formed on the contacting surface C, so the total flow rate sectional area of the gap A is reduced and the amount of exhaust gas admitted into a detection part 17 through the contacting surface C is reduced. Therefore, when the amount of oxygen in the hollow part 4 is controlled, the voltage applied between the electrodes 18 and 19 is lowered.
