Patent JP-H02306233-A (JP)
Title: Digital x-ray device
Inventor: TAKEDA SHIRO
IPC: G01T1/00
Filed: 1989-05-20
Abstract: PURPOSE:To prevent an erroneous diagnosis by comparing the initial state of a stimulable phosphor sheet with the state thereof at the time of being used and giving warning when an abnormal image element exceeds a threshold. CONSTITUTION:A normalized correction factor(continuous line) obtained in a state where an object does not exist just when the phosphor sheet is ex changed is stored in a memory 5 for initial correction factor. Then, a normalized correction factor(dotted light) obtained in a state where an object does not exist when a power source is turned on in the morning is stored in a memory 6 for correction factor. Since brightness in the parts A and B of the dotted line is darker to be equal to or exceeding the specified threshold, the image elements in such parts is counted to be displayed as the abnormal image ele ment. When the abnormal image elements, for example, exceeds 1% total image elements or when the abnormal image elements consecutively exceeds 0.1% total image elements by number, the warning message such as the exchange of the stimulable phosphor sheet is displayed by judging that the sheet can not be used. Thus, the state of an X-ray image detection system is accurately displayed and the device serves the prevention of the erroneous diagnosis.

Inventor: YAMAGUCHI SHOJI
IPC: G11B5/85
Filed: 1985-06-12
Abstract: PURPOSE:To form a soft magnetic layer having low coercive force and high magnetic permeability in the stage of forming the soft magnetic material by executing sputtering on the upper stream of the moving direction of a substrate while maintaining the forming layer at the potential lower than the plasma potential on the down stream thereof. CONSTITUTION:One end of the thin 'Permalloy(R)' film MM continuously formed by sputtering on the film substrate BD' which moves under taking up contacts with a take-up guide roller 6 which is kept biased to the potential lower than the potential of an anode electrode 8. Therefore the film MM self-biases the surface of the substrate BD' to the potential lower than the plasma potential by the conductivity of the film MM itself after the above-mentioned contact. The film MM to be formed thereafter by sputtering is thus the soft magnetic layer having the excellent soft magnetic characteristics such as low coercive force (low Hc) and high magnetic permeability (high mu).

Title: Delta modulator-demodulator
Inventor: NAKABAYASHI SUMIE
IPC: H03M3/02
Filed: 1985-06-14
Abstract: PURPOSE:To decrease granular noise when a signal amplitude is large by converting an input signal in exponential way before delta modulation and converting the demodulated signal in a logarithmic way after the delta demodulation. CONSTITUTION:An analog input signal is A/D-converted by an A/D conversion section 11, fed to an exponential conversion section 12, where the signal is converted in an exponential way. In the exponential conversion, for example, an exponential function is approximated by a polynomial, whichh is calculated by a digital signal processor. The data converted in an exponential way is delta-modulated by a delta modulation section 13 and the result is sent as 0, 1 bit stream. On the other hand, the delta-demodulated data being the 0, 1 bit stream is received, then it is demodulated by a delta demodulation section 14, fed to a logarithmic conversion section 15, where the data is converted in a logarithmic way. In this logarithmic conversion, the same method as the exponential conversion is used. The data converted in a logarithmic way is D/A-converted by D/A conversion section 16 and an analog output signal is obtained.

Title: Apparatus for displaying plane or thin layer range of human eye
Inventor: YOOZEFU BIRE
IPC: A61B3/12
Filed: 1985-06-14
Abstract: This invention enables comprehensive examinations of the front parts of human eyes, reliably provides precise and easily interpretable pictorial representations of the examination field, enables gentle examinations of short duration and is comparatively simple in construction and application. In this arrangement, a confocal arrangement of a pinhole relative to the focal plane of a microscope objective causes a scanning laser light bundle to be focused on the examination field. Use of a microscope objective for focusing the scanning light bundle enables a narrow limitation to be provided in the depth of the examination field. This light bundle may have a relatively wide cross section. Use of a pinhole to focus on a photodetector the light reflected from the eye causes a favorably high signal-to-noise ratio to be produced and image information data to be provided within minimal time intervals such as small fractions of a second to at most a few seconds. An electrically controllable active mirror operable within the beam-shaping optics of the scanning field may be included to displace the plane of the examination field relative to a median position. This active mirror may be controlled to operate as different types of mirrors including a plane mirror. Therefore, data for a high-resolution subdivision of an examination object into a plurality of thin layer-shaped examination fields may be obtained. Such data can be processed by an appropriate computer-controlled display unit and displayed by the unit as representations of the examination object along arbitrarily oriented and/or shaped sectional planes or curved areas.
