Title: Optical speed sensor
Inventor: YUASA HAJIME
IPC: G01P3/36
Filed: 1989-12-08
Abstract: PURPOSE:To measure speed by a space filter system in light scattering environment such as the water by alternately emitting two kinds of light passed through a slit in a lattice form and separating reflected light to measure the respective luminous intensities. CONSTITUTION:Lights are alternately emitted from the green light source G and blue light source B of the light projection part of an unmanned submarine to illuminate the sea bottom. The light is split by a mirror 34 through the condensing lens 30 and lens 38 of a light detection part 12. The split light beams are respectively allowed to pass through green and blue filters 40, 41 and the luminous intensities thereof are detected by photomultiplier tubes 42, 43. The detection signals of the photomultiplier tubes 42, 43 are applied to an operation circuit 50 through the differential amplifier 46 and frequency counter 48 of an operation part 44 and speed is operated from the pitch between the same colors of the lattice pattern projected to the sea bottom. By this method, speed can be measured in light scattering environment such as the water by a space filter system.

Filed: 1990-11-22
Abstract: PURPOSE:To ensure the erasing of data without using a complicated circuit constitution and recovery processing and to improve operability by actually recording the specified data including an erasing flag and error correcting codes, and using a block on a recording medium as an erasing block. CONSTITUTION:A writing circuit 25, a reading circuit 26 and the like are provided under a microprocessor 22.

Title: Image processing system
Inventor: SAKAGAMI HIROFUMI
IPC: H04N19/91
Filed: 1989-12-11
Abstract: PURPOSE:To keep the approximately constant quality of a compressed image by changing the value of a scale factor according to the contents of a picture to be compressed. CONSTITUTION:When the image data is compressed, the scale factor is changed at quantization in accordance with the contents of an image to be compressed are coincident with a fine part of a pattern where the image signal has a sudden change or a flat part of the pattern where the image signal has a slow change. A fact whether the contents of the image are coincident with the fine or flat part of the pattern is decided by detecting the DCT spectrum of each of those blocks forming a sheet of image. Thus an area ratio is obtained between the fine and flat parts of the pattern in a sheet of image. Then a scale factor is obtained in accordance with an area ratio obtained based on the relation between the area ratio obtained previously via a visual test and the scale factor. The scale factor thus obtained is multiplied by each threshold value of a quantized matrix for the execution of the quantization.

Filed: 1987-12-17
Abstract: PURPOSE:To prevent the production of a pseudo image such as moire image by providing a control means selecting an X-ray focus size in response to the visual field size or in response to the said visual field size and the magnification. CONSTITUTION:A system controller 11 gives a control signal to select a large X-ray focus size in case of a large visual field size and to select a small X-ray focus size in case of a small visual field size to an X-ray controller 9 and an I.I. visual field controller so as to make the cut-off frequency of the MTF at the X-ray focus nearly coincident with the Nyquist limit frequency of a discontinuous sampling image pickup element. Thus, as a result, the spatial frequency component over the Nyquist limit frequency depending on a CCD image pickup element 3 is suppressed in the I.I. output and the occurrence of the pseudo image such as moire image is prevented to the utmost.

Filed: 1987-12-16
Abstract: PURPOSE:To detect voltage variation instantaneously without any time delay if the abrupt voltage variation such as a power failure and a hit occurs by providing 1st and 2nd phase-locked loops, a differential amplifier, etc. CONSTITUTION:When an AC voltage V1 is outputted by a power source, the 1st phase-locked loop 13 outputs a voltage V2 and the voltage-controlled oscillator 15b in the 2nd phase-looked loop 15 outputs a voltage V2. Further, a voltage V3 outputted by the loop 15 is generated by shaping a rectangular wave of a voltage V21 into a sine wave and its phase is further 90 deg. delayed behind the voltage V2 of the loop 13. Then an inverter 17 corrects the phase difference and outputs a voltage V4. This voltage V4 is in phase with the voltage V1 and even if the power source has a hit an invariably constant sine wave current is obtained. Then the differential amplifier 19 to which the voltages V4 and V1 are inputted calculates the deviation between the both and a voltage signal V5 is outputted in the hit. For the purpose, the signal V5 is detected from an output terminal 21 to detect the abrupt voltage variation.
