IPC: G05D1/10
Filed: 1989-05-20
Abstract: PURPOSE:To dock a spacecraft to an objective artificial satellite by operating a gripper with observing a monitor image receiver. CONSTITUTION:A spacecraft 1 on which a TV camera 11 is loaded should be roughly aligned to project a target mark setting plate of an artificial satellite 2 on a monitor image receiver. Then a gripper 18 should be operated to overlap an image of target mark 20 on an image of target mark 3 in a monitor 16. Thus by simulating the relative location of the satellite 2 observed from the spacecraft 1 on the monitor image receiver, the objective position of the spacecraft 1 can be aligned to the satellite 2. Consequently, an operator 17 is required only to adjust the image of the target mark 3 displayed on the monitor image receiver 16 to the position and size to allow docking. Even though the operator has no detailed knowledge of the characteristics of propelling unit or control features of the spacecraft 1, smooth and reasonable operation can be realized.

IPC: H04B1/40
Filed: 1984-06-21
Abstract: PURPOSE:To quicken the lock-in speed and to widen the lock range by setting a band pass filter for extracting pilot signal to an optimum band width respectively at unlocking and locking of AFC. CONSTITUTION:A lock discriminating circuit 13 of a PLL-AFC system outputs an output signal 0 at unlock state and outputs an output signal 1 at lock state. The bandwidth of a band pass filter 14 is switched to a broad band characteristic when the output signal of the circuit 13 is 0 and to a narrow band characteristic when the output signal is 1. Thus, the band pass filter 14 has the broad band pass characteristic at the unlock state and the S/N of a pilot signal is deteriorated more or less by the effect of a sound signal, but the lock-in speed is quickened and the lock range becomes wider. Since the band is switched to the narrow band after lock, the S/N of the pilot signal is improved and the accuracy for tracking frequency is increased.

Title: Agent and method for inspecting oil leak
Inventor: TANI MINE
IPC: G01M3/20
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To detect even a minute leak with high sensitivity by making an inspection agent contain an oil-soluble dye of not larger than a specified particle size and a white fine powder by a specific weight ratio. SOLUTION: 0.1-5 wt.% of an oil-soluble dye having a particle size not larger than 10 μm and 5-70 wt.% of a white fine powder are contained, to make the agent a water-based dispersion type agent for inspecting oil leak. The inspection agent is applied to an inspection body. If oil leaks, the dried white fine powder sucks the oil by the capillary phenomenon, dissolves the fine, uniformly dispersed oil-soluble dye and forms an indication pattern of dark color on the white coat film. When the particle size of the oil-soluble dye exceeds 10 μm, the oil-soluble dye becomes hard to dissolve in the leaking oil of a minute amount. When the oil-soluble dye is added by smaller than 0.1 wt.%, coloration performance becomes poor. If the dye is added by over 5 wt.%, a point of the leak is difficult to distinguish from a background. The white fine powder is better to have high whiteness.  The dried film is deteriorated in whiteness and hard to distinguish if the powder is added by smaller than 5 wt.%, and a viscosity of the dispersion liquid is increased to worsen the coating properties if the powder is contained over 70 wt.%.

Filed: 1995-05-26
Abstract: PURPOSE: To provide a discharge lamp lighting device capable of preventing the occurrence of extinguishment upon the sudden drop of the voltage of a DC power supply, as well as the occurrence of over-output upon the sudden rise thereof. CONSTITUTION: A control section 4 varies the duty of a PWM signal for actuating the switching element Q0 of a step-up circuit 1 over the prescribed time from the polarity inversion of output from an inverter 2, depending on the fluctuation of the voltage Vin of a DC power supply E. In other words, when the voltage Vin is low, the on-duty of the PWM signal at polarity inversion is made large. On the contrary, the on-duty is reduced, when the voltage Vin is high. As a result, the appearance of extinguishment at the time of polarity inversion can be prevented, when the voltage Vin of the DC power supply E is low. On the contrary, the appearance of over-output can be prevented, when the voltage Vin is high.

Abstract: PURPOSE:To enable to employ an anti-vibration rubber having a low spring constant, by adding a stopper for restricting excessive oscillations in all radial directions orthogonal to the axis of inner and outer cylinders. CONSTITUTION:Vibrations arising from the rotation of an engine are absorbed by the anti-vibration rubber 4, while weak oscillations of the engine in longitudinal and transverse directions and combined directions thereof, namely, in all radial directions orthogonal to the axis of the inner and outer cylinders 1a, 2a accompanied by impulsive accelerations, thrusts or the like during steaming of a ship are absorbed by elastic deformations of the rubber 4 within the range of a gap l1. Excessive oscillations in all directions of the engine 8 are restricted by stoppers 12, 13, 14. In addition, since the stoppers 12, 13, 14 are located below an upper plate 1, they are free of fear of interferring with a setting operation for the engine 8. Accordingly, excessive vibrations in not only vertical directions but also longitudinal and transverse directions and combined directions thereof can be restricted, the spring constant of the anti-vibration rubber can be so set as to produce a sufficient anti-vibration effect, and increase in the creep amount of the anti-vibration rubber can be prevented by each of the stoppers.
