摘要： An information processor which recognizes characters handwritten on the surface of a tablet-like plate based on the handwriting and strokes and searches a dictionary for the characters and words as the notation to convert them into a mixed character string of KANA and KANJI. The information processor is provided with a same-shape character conversion dictionary (8) which stores the characters having shapes which are the same as or similar to that of the character recognized by a character recognizing means (2). When another character having the same or similar shape as or to the recognized character exists, the dictionary (8) is searched for the another character, and the searched another character and a character or word, as the notation, corresponding to the recognized character, are retrieved from a mixed writing conversion dictionary (7) by a same-shaped character collectively retrieving means. The information processor then converts the character or word retrieved by the retrieving means (5) into a KANA-KANJI mixed character string by means of a mixed writing converting means (3) and displays the character string on a displaying means (4).

摘要： A semiconductor integrated circuit including a Galois multiplier which enables multiplication using a plurality of different primitive polynominals. The semiconductor integrated circuit (1) includes a Galois multiplier (2) which is used for Galois multiplication of the elements of a Galois field GF(2 ). The coefficients (5, 4) of the elements of the Galois field GF(2 ) which are the multiplier and the multiplicand and the coefficients (6) of the primitive polynominals are inputted to the Galois multiplier. The coefficients are arithmetically operated for different primitive polynominals with the same hardware to obtain Galois multiplication results. A coefficient setting means (3) which supplies the coefficients of the primitive polynominals of the Galois field GF(2 ) is provided. With this constitution, the Galois multiplier can perform multiplication on the Galois field corresponding to the primitive polynominals supplied by the coefficient setting means. The semiconductor integrated circuit, therefore, can be versatilely applied to encoding or decoding of the error correction codes of the different Galois fields which are defined for the different primitive polynominals respectively.

摘要： Line drawing information expressed by characters and lines can be captured with an image scanner only when the information is printed on a sheet of paper having an appropriate size and the user can directly handle the paper. When the information is posted on a display panel or a wall, the acquisition of the information is impossible. Line drawings are different from ordinary video image in that the drawings are monochromic, their gradations are binarized, and their spatial frequencies are high. In order to input line drawings having these features, the image pick-up system of an electronic camera is provided with a mode switching means for monochromic high-resolution input, a means which converts picked-up line drawing information into monochromic binarized vector information, and a means which switches these two means at once at the time of picking up line drawing information.
摘要翻译：只有当信息被打印在具有适当尺寸的纸张上并且用户可以直接处理纸张时，才能用图像扫描仪捕获由字符和线表示的线条图。当信息发布在显示面板或墙壁上时，信息的获取是不可能的。线图与普通视频图像不同，因为图纸是单色的，它们的灰度被二值化，并且它们的空间频率高。为了输入具有这些特征的线条图，电子照相机的图像拾取系统设置有用于单色高分辨率输入的模式切换装置，将拾取线描绘信息转换为单色二值化矢量信息的装置，以及在拾取线条图画信息时立即切换这两种装置的装置。

摘要： A multi-projection image display device using a plurality of image projectors to form one picture on a screen, in which images projected from the projectors are smoothly connected with one another, so that seams of the images do not appear conspicuously. The image display device has projectors (0121, 0122, 0123, 0124) and a screen (0140) laid out in such a manner that maximum image projection ranges (0151, 0152, 0153, 0154) of the respective projectors ovelap the adjacent ranges. An image signal control unit (0110) for processing an image signal supplied from an external image input (0180) has, therein, a member for cutting out a partial image area dealt with by each projector, an image converting member for performing geometric transformation and local color correction of the partial image, and an arithmetic control member for controlling the image converting member on the basis of image information inputted from a screen state monitor camera (0130). With this structure, smoothing of the seams between the images may be realized simply by image signal processing, and precise adjustment of the optical system of the projectors becomes unnecessary.

摘要： The ratio BrOR of the residual magnetic flux density in a circumferential direction to the residual magnetic flux density in a radial direction is 0.95 - 1.05 and the ratio HcOR of the coercive force in a circumferential direction to the coercive force in a radial direction is 1.05 - 1.2 in the substrate surface of a magnetic recording medium. Therefore, a high output resolution, a low medium noise and a high track recording density are simultaneously achieved in recording at a high line recording density. When a magnetic storage apparatus is constituted by using a high S/N magnetic recording medium like this, a magnetic disc apparatus which has a high surface recording density, is low in cost and small in size, and a large capacity and a high reliability can be provided.

摘要： A high-frequency power amplifier circuit device, with the frequency of the operating band between 500 MHz and approximately 10 GHz and power level of not lower than 0.5 W, has a problem to be settled that no increase in power level can be expected in proportion to the increase in the gate width of a power transistor. In addition to the solution of the above problem, an optimal high-frequency power amplifier circuit device and a high-frequency transmission system using the device are constituted to reduce the space in the matching circuit, to improve the linearity and to prevent oscillation in a power transistor (10) and an input/output matching circuit in such a way that the grounds (2) and (4) of an input-side strip line (61) and output-side strip line (62) are separated from each other and the grounds (2) and (4) are respectively connected to an input-side ground electrode (24a) and output-side ground electrode (23a) provided on a semiconductor chip carrying the power transistor (10). Consequently, the effective source impedance component which has been the cause of the deterioration of high-frequency power amplifier circuit in mutual conductance can be reduced.

摘要： Optical signal communication equipment and optical communication system which can be suitably used even when the transmitting speed and capacity of information transmitted by using optical signals are increased. On the optical signal transmitting side, signal light is generated by causing induced emission in an active medium by supplying exciting light to the medium in accordance with transmitting signals. The exciting light is supplied to the active medium in such a way that naturally emitted light is made incident to a semiconductor layer and the component of the light having a specific wavelength is Bragg-reflected by modulating the refractive index of the semiconductor layer by impressing the voltage pulse correspdoning to the transmitting information upon the semiconductor layer, and then, the reflected light is supplied to the medium as the exciting light. Since the Bragg reflection and associated induced emission show excellent responsiveness to voltage signals having pulses widths of 1x10 second on shorter, an optical communication system which can transmit optical signals at a transmitting speed of up to 100 Gb/s can be realized.
