Patent JP-S61250624-A (JP)
Title: Optical element
Inventor: YUASA SATOSHI
IPC: G02F1/17
Filed: 1985-04-30
Abstract: PURPOSE:To obtain a distinct image having high contrast and resolution and to eliminate the limitation in an angle of field by sandwiching a liquid layer contg. a surface active agent having a Krafft point between a substrate and protective plate. CONSTITUTION:The greater part of the surface active agent deposits and exists in a solvent in the state (state below the Krafft point) in which the liquid layer 2 is not heated and therefore the incident ray 6-2 on the low-temp. region 4a of the liquid layer 2 scatters (diffuses). On the other hand, the surface active agent deposited in the prescribed position dissolves in the solvent and the liquid layer 2 exhibits light transmittability when the prescribed position of the liquid layer 2 is heated to the Krafft point or below by a heating means from the outside by the irradiation of, for example, an IR beam 5 according to an information signal. The incident ray 6-1 on the heated region 4 passes therefore approximately straightly through the liquid layer 2 and is emitted from the substrate 1. The heated region 4 restores the original scattering state when the temp. falls.

Abstract: PURPOSE:To specify a ground-fault circuit without being influenced by the amplitude of a residual current normally by comparing the phases of higher order zero-phase except the fundamental wave component of the zero-phase current by means of zero-phase current transformers provided to respective wirings. CONSTITUTION:When a ground-fault trouble occurs, a current is applied to a ground-fault channel selector DG through zero-phase current transformers ZCT1-ZCTn, and currents of specific order components are removed by filters 1-1-1-n. Since the logic circuit 32-1 of a phase discriminator 3 inputs the signals of a phase inverter 31-1 and waveform shapers 2-1-2-n, its superposed angle is output with a predetermined width. Further, waveform measuring circuits 33-1-33-n output pulse waveforms since the output of the circuit 32-1 has a width of approx. 180 deg. of an electric angle. Then, an output circuit 4 outputs an operation command to a corresponding circuit breaker CB when the output pulse of the circuit 33-1 becomes a predetermined value.

Title: Moving body detecting method

IPC: H04N7/18
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To accelerate moving body detection processing by equalizing the density value of common stationary body section by requantizing the input frames of pixel estimated as a moving body section and its nearby pixel while alternately inverting their quantizing directions. SOLUTION: The changes of coordinate data in the respective input frames of the pixel estimated as the moving body section among pixels consisting of the input frame and its nearby pixel and moving directions in the respective input frames of such a pixel and its nearby pixel are detected. Namely, by a frame memory, the density value of inputted signal is converted to an electric charge by a positive logic and by an inverter circuit, the density value of inputted signal is converted to an electric charge by a negative logic. Then, these electric charges are sent to a synthesizer circuit and the both are synthesized and compared. By this synthesizer circuit, the pixels of the same luminance in both the electric charges are canceled each other.  Namely, the density of stationary section is equalized in an output signal and the pixel regarded as a moving body with the different levels of luminance between both these pixels is extracted.

Title: Low-loss leakage transmission line
Inventor: NISHIDA SHIGEO
IPC: H01Q13/20
Filed: 1979-07-18
Abstract: PURPOSE:To ensure a low-loss transmissin even with a large thickness of the cylindrical dielectric substance, by setting the thickness to a value of odd-times as much as 1/4 of the electromagnetic wavelength in the dielectric substance. CONSTITUTION:Cylindrical dielectric substance 1 is made of the dielectric material having a comparatively small dielectric loss and a large dielectric constant; and its inner diameter 2d1 is set large enough in comparison with the using wavelength. At the same time, the air or the gas having a low loss exists in the inner space of substance 1. And the thickness d2 of substrate is set to a value of almost odd-times as much as 1/4 of the electromagnetic wavelength in substance 1. As a result, the energy of the electromagnetic wave becomes munimum at the portion of substance 1, and at the same time the energy of the electromagnetic wave leaking outside  becomes minimum. In such leakage mode, the greater part of the electromagnetic  wave energy propagates in inner space 2 to secure a low-loss transmission. Furthermore, loss layer 3 is provided at the outer circumference of substance 1 to absorb  the leaked energy. Thus the effect of the transmission can be more enhanced.
