Title: D/a conversion circuit
Inventor: YONEZAWA EIJI
IPC: H03M1/68
Filed: 1991-07-15
Abstract: PURPOSE:To obtain the high-accuracy and high-resolution digital/analog (D/A) conversion circuit by adding the analog outputs of high-order and low-order D/A converted vertically bisected for digital signals and the error compensating analog output of the high-order D/A converter. CONSTITUTION:High-order digital data are inputted to a high-order D/A converter 1, high-order analog signals are outputted, the data are inputted to an error table 2 as well, and error compensating data are taken out. These compensation data are added to low-order digital data by an adder 3, inputted to a low-order D/A converter 4 and converted to low-order analog signals. Since the converter 4 outputs the sum of the low-order analog signals and the error compensating signal, a signal turning a reference voltage from an IC 5 to the double size of a minimum output from the converter 1 can be outputted. The error compensating data and the low-order digital data added by the adder 3 are converted to low-order analog data by the converter 4, synthesized with high-order analog signals by an analog adder 7 and outputted.

Title: Method and device for inputting handwritten character
Inventor: CHATANI KIMIYUKI
IPC: G06F3/0488
Filed: 1993-08-13
Abstract: PURPOSE:To accurately segment a subordinate character by deciding the subordinate character according to features of an image, a subordinate character and a subordinate character segmentation rule when an input line is the same as a line which is inputted before. CONSTITUTION:For a decision processing for subordinate character segmentation, the subordinate character segmentation rule stored in a subordinate character segmentation rule data base and line data stored in a line data base are used. In response to input to a new line, a processing for recognizing a character by combining subordinate handwritten characters inputted to the line so far is started. For example, when characters 'bright' are inputted, six subordinate characters (a)-(f) are generated from those characters. Then only a necessary number of adjacent characters among the six subordinate characters are combined. Further, the respective characters are recognized from the respective combinations. Consequently, the handwritten characters can accurately be recognized.

Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To increase the spring force without changing the length or the inside diameter of a cylinder by providing a return spring to urge a rod in a direction to press a pulley arm outside the cylinder. SOLUTION: A return spring 17 is provided outside a cylinder 11, one end of which is supported by a flange 25 at a lower part of an outer circumference of the cylinder 11, the other end of which is received by a spring seat 26 at a tip part of a rod 15, and a spring seat 26 is pressed to provide the outwardly projecting property. Thus, the return spring 17 is less subjected to the limitation of the length, and the return spring 17 which is large in total length and large in spring force can be assembled. The spring force of the return spring 17 can be largely without changing the inside diameter of the cylinder so as to be sufficiently adaptable to the required belt tension.  Even when the return spring 17 with a large set value of the spring force is required, the length or the inside diameter of the cylinder 11 need not be increased, and the quantity of the working fluid is increased.

Filed: 1988-08-15
Abstract: PURPOSE:To eliminate the play of a disk in a cartridge when it is not used by providing a recording medium abutting part abutted with a recording medium to hold at a shielding position and to release abutting at an exposed position on a shutter. CONSTITUTION:When the shutter 3 shields a read/write hole 2a and a driving hole 2b, it is held at the shielding position by the pressing force of a spring 4, and a disk hub 1a is sandwiched between semilunar shape abutting parts 3c and 3d on the shutter 3 receiving the pressing force in the diameter direction of the disk 1 and the end face 2d of the driving hole 2b, and also, it is sandwiched in a thickness direction between opposite abutting planes 3a and 3b of the shutter 3. When the shutter 3 is cleared from the read/write hole 2a and the driving hole 2b, the disk 1 and the disk hub 1a are opened in the diameter direction and the thickness direction, then, the disk 1 can rotate smoothly. In such a way, it is possible to prevent the play of the disk 1 in the cartridge 2 from being generated when it is not used.

Title: Optical communication system using composite led
Inventor: NAKATANI TOSHIO
IPC: G02B6/00
Filed: 1987-08-12
Abstract: PURPOSE:To perform a multiplex communication by one optical fiber by achieving the function of an LED as a photodetector, and employing a composite LED having at least two LEDs including different wavelengths and disposed in parallel in one case. CONSTITUTION:Two communication equipments having composite LEDs 2, 2' near a light transmission ports of bodies 1, 1' are oppositely provided, and a sole optical transmission passage is formed through one optical fiber between both the composite LEDs. The emitting and photodetecting functions of the LEDs of the composite LEDs 2, 2' can be arbitrarily electrically switched by input/output circuits contained in the equipments. That is, the LEDs in the composite LEDs 2, 2' separately perform functions as a light emitting element at the time of transmitting and as a photodetector at the time of receiving by the input/output circuits, and particular operations of multiplex communications can be performed by one optical fiber. Further, since a whole system can be remarkably reduced in size and the equipments for transmitting and receiving have the same structures, the cost reduction due to the unitary production can be expected.

Title: Illuminance correcting device for slit exposure copying machine
Inventor: MURAI TATSUYA
IPC: G03G15/043
Filed: 1989-08-04
Abstract: PURPOSE:To correct illuminance properly over a wide power variation range by providing a light shield member which has a light shield part shaped so as to shield part of an optical path and a displacing means which displaces the light shield member about a lens in the optical axis direction by length corresponding to variable magnification. CONSTITUTION:The light shield member 42 having the light shield part which is so shaped as to shield part of the optical path is provided for slit-lengthwise illuminance correction of a cosine 4th-power rule, etc., and displaced about the lens by the displacing means 43 in the optical axis direction by the length corresponding to the variable magnification. Therefore, even if the distance between the lens and a document and the distance between the lens and a photosensitive body vary by the lens movement caused by variation in the magnification, the light shield member 42 also shifts in position in the optical axis direction at the same time and the lens 10 and light shield member 42 shift in the relative position in the optical axis direction corresponding to the variable magnification. Consequently, even if the magnification varies, the quantity of light shielding corresponding to the same view angle is held constant. Consequently, the proper illuminance correction is enabled over the wide power variation range.
