Title: Focus detecting method
Inventor: KONDOU TOSHIHIRO
IPC: G02B7/34
Filed: 1980-10-14
Abstract: PURPOSE:To detect an in-focus state, by measuring the contrast of an image sent from the output of a photodetector and detecting electrically that the contrast of the image becomes maximum. CONSTITUTION:An image of a subject is formed on the surface of a diffraction grating 2 by an objective lens 1. The image of the grating 2 is formed through an image forming lens 4 on a photodetector 3 which is set at the back of the grating 2. Thus only the light that forms a part of the image is irradiated on the receiving surface of the photodetector 3. When the image contrast is measured while the focus is shifting, the contrast becomes higher toward an in-focus state. And the contrast becomes highest in the in-focus state and increases when the image gets out of focus. Accordingly the in-focus moment can be detected by detecting the maximum contrast of image.

Title: Method and equipment for determining outline in space having density distribution
Inventor: SUTEIIBUN ROBURETO
IPC: G06T5/00
Filed: 1994-06-24
Abstract: PURPOSE: To decide an outline in a space having gray level change by establishing energy function constituted of an inside part being the function of curvature and an outside part due to the gray level change, and continuously changing the positions of vertexes until this function reaches the minimum value. CONSTITUTION: An outline is an object constituted of vertexes 11, 12, 13,... connected by straight sections or edges 14, 15, 16,.... The position of a vertex Vi is expressed with a vector (p)1 , and the vertex Vi and a vertex Vi+1 are expressed with a vector (d)i , and here a coordinate system assumes a straight coordinate. Deformation occurs due to the combination of forces acting on the vertexes, and acceleration which is generated as a result in the vertex Vi is expressed with a vector (a)i . The other feature of the vertexes important to the dynamic behavior of the outline is the speed expressed with (vi) for the vertex Vi . The length (d)i of an edge section expresses the local resolution of the outline, and when it is large, the outline can not follow-up the small- scaled change in image characteristic energy distribution.

Title: Optical receiver
Inventor: KASHIWAGI KEIZO
IPC: H04B10/2507
Filed: 1993-06-15
Abstract: PURPOSE:To guarantee logic when the thresholding of a signal received by a photodetector is performed even in transient response by attaching the same transient characteristic for the rise of a common power source on both amplifier output and a reference signal. CONSTITUTION:When a power source Vcc is applied, the potential of a connection point 36 connected to the output terminal on one side of a comparator 13 rises in curved shape by a second time constant circuit 22. The similar change is shown at the potential of the input terminal on the other side of the comparator 13 and that of the connection point 38 of an amplifier 12 by a first time constant circuit 21. Therefore, assuming that an optical signal is received by the photodetector 11 at a time t1 soon after the power source is applied, the potential of the connection point 38 by such reception of the optical signal is rocked in both positive and negative directions centering about reference potential, and a digital signal 23 can be generated by surely binarizing the output signal of the amplifier 12 by the comparator 13.

IPC: G06F12/06
Filed: 1992-06-04
Abstract: PURPOSE:To provide a control signal generator capable of easily controlling the generated signal by reloading an address setting value or a timing setting value. CONSTITUTION:Reloadable setting address information is stored in a setting register 8 and a CPU specifies the address value through a bus line 70 to perform an access. Since the setting address information itself is not stored right after turning on a power supply, the CPU can not perform access to a ROM 93 and can not fetch a program itself. Thereby, the CPU performs access to the ROM 93 based upon an address value fixed and stored in the 1st initial address generating circuit 3 as a software value.

Inventor: SOGO HIROYUKI
IPC: H01P1/205
Filed: 1985-07-01
Abstract: PURPOSE:To increase the attenuation at out-band by opening an H plane side of a filter main body, fixing a dielectric board whose earth conductor layer has a function of the H plane to constitute a waveguide part and forming a strip line as a branching path at the outer side face of the dielectric board. CONSTITUTION:Since the dielectric board 11 provided with a function of the H plane is fixed to the opening face of the filter main body 10, the filter main body 10 acts like a waveguide. Then the strip line 20 as the branching path is provided at the outer side face of the dielectric board 11. The strip lines 20 are formed as a couple of lines opposed to each other in an L-shape, the length of branching path is adjusted by connecting a desired part of a vertical part of the opposing L-shape with an adjusting conductor plate so as to adjust easily the phase difference between the branch path and a main path. Thus, no branch waveguide is required and the band-pass filter with simple structure, low cost, comparatively simple adjustment of the branch path and a desired filter characteristic is obtained.
