Abstract: A polishing apparatus which can efficiently polish an entirety of a back surface of a substrate, with the back surface facing downward, is disclosed. The polishing apparatus includes: a substrate holder configured to rotate the substrate; a polishing head configured to polish the back surface of the substrate; a tape advancing device; and a translational rotating mechanism configured to cause the polishing head to make a translational rotating motion. The substrate holder includes a plurality of rollers which are rotatable about their own axes. The plurality of rollers have substrate-holding surfaces capable of contacting a periphery of the substrate. The polishing head is disposed below the substrate-holding surfaces. The polishing head includes a polishing blade configured to press the polishing tape against the back surface of the substrate, and a pressing mechanism configured to push the polishing blade upward.

Abstract: In a case of right and left eye fundus image sensing in a mass health examination, the alignment of an anterior segment of an eye to be examined is performed first (S101). When the alignment of the anterior segment of eye is completed, image sensing light intensity is set (S102). The alignment of a fundus segment of the eye to be examined is performed (S103). Furthermore, an image of the fundus of the eye to be examined is sensed by a sensing switch being pushed after the completion of focus adjustment (S104). Next, an optical base unit is moved so that the image sensing of another eye can be performed (S105). A left or right eye detection unit detects that an eye for image sensing is changed with the move of the optical base unit. When the eye for image sensing is changed, an image sensing light intensity setting unit sets image sensing light intensity by adding a predetermined amount, or changing the sets image sensing light intensity according to a diameter of a pupil (S106).

Abstract: Color information having R, G, B components is entered. When an optic nerve head contained in the color image information is designated by an image processor and region designation unit, an image compression unit encodes the B component, which is included among a plurality of color components in this designated region, at a compression rate lower than that in a region other than the designated region, and encodes the G component and the B component other than in the designated region at a higher compression rate.

Abstract: A sheet antenna which comprises a substrate sheet, a layer of antenna element composed of a conductive material and a carbon-containing layer, the layer of antenna element and the carbon-containing layer being laminated on the substrate sheet is disclosed. The sheet antenna is superior in receiving and/or transmitting sensitivity of electric waves.

Abstract: An image processing apparatus includes a memory for storing data representing a digital mask pattern for extracting only a plurality of two-dimensional discrete images from a first image, a generator for generating data representing a synthesized image including a plurality of discrete two-dimensional images from the first image with the digital mask pattern, a display for displaying the synthesized image and a second image in an overlapped state, and a memory for storing data representing first and second images so that a common image portion, common to the first and second digital images is stored therein.

Abstract: An ophthalmologic apparatus characterized by the provision of a device for introducing thereinto an eye fundus image at a point in time earlier than the point in time of view field measurment, a device for measuring the field of view of an eye to be examined, and a device for superposing the introduced eye fundus image and the output of the view field measuring a device, one upon the other, and compounding them.

Abstract: A still picture video telephone apparatus adapted to transmit and receive, through a telephone line, still picture information from a television camera or the like, during a telephone call, includes a picture memory for storing a plurality of pages of picture information consisting of a camera-taken picture memory portion which rewrites still picture information input therein delivered from the television camera at intervals of a predetermined period, a self-prepared picture memory portion which stores desired still picture information until arrival of a rewrite instruction, and an incoming picture memory portion which sequentially rewrites still picture information therein upon receipt of still picture information when its storage regions are filled up, memory region input information for setting up regions for the self-prepared picture memory portion and the incoming picture memory portion within the picture memory, and picture memory control circuit for controlling still picture information input to and ou
