Abstract: PURPOSE: To facilitate miniaturization by forming a keyboard of a flexible material, and reducing the size without damaging the operability of the keyboard when it is not used. CONSTITUTION: A key main body 14 is formed of a conductive flexible elastomer material, and when a key 10 is pressed at an activating position, a long side face 18 of the key 10 is compressed in the same way as right and left side faces 20. Then, the key 10 is exactly brought into contact with the same spot 26 as a lower print circuit board 24. Also, the elastomer material forming a large part of a keyboard 50 is compressed between respective keys 10, and accordion pleat 52 is formed with each key 10. On the other hand, the keyboard 50 formed of a hard impact-resistance plastic is held at an open position while a middle sliding member 74 is locked between the positions of members 72 and 76 at an extending position. Then, the keyboard 50 is compressed while pins 79 of the members 72 and 76 are moved along a rail 78 on the member 74 at a closed position. Thus, this device can be made extremely compact when it is not used.

Abstract: PURPOSE: To minimize scan errors of a scan printer assembly by equipping a control means for giving roller rotation to move a paper sheet so as to eliminate errors onto a drive means for rotating a roller. CONSTITUTION: When a processing circuit 22 received a control signal for feeding paper so as to print one scan distance during print operation, the processing circuit determines which roller 30 is feeding paper. Next, the processing circuit 22 calculates a desired rotation angle at a specific position of the roller 30 and makes access to a memory device 21. The processing circuit 22 obtains the position information from a position feed back circuit 25 and the position is a point on the roller 30 where the radius is perpendicular against the print paper. When a desired rotation velocity is obtained from the memory device 21, the processing circuit 22 transmits a signal to control the movement of a drive motor 12 to an amplifier 23 and the drive motor 12 which increase/ decrease the size of a step to correct an error.

Abstract: PURPOSE: To electrically connect a conductor with a circuit substrate by attaching a conductive elastomer, which is to be joined to a pad on the surface of a circuit substrate, to a conductor of a flexible circuit substrate and press- connecting the conductive elastomer to the pad. CONSTITUTION: A flexible circuit substrate 24 is constituted of a flexible dielectric material 22 and a conductor 20 and a conductive elastomer 26 is attached to an end part of the conductor 20. A plate 28 which press-connect the elastomer 26 to a surface pad 16 of a circuit substrate 12 by applying pressure to the conductor 20 and the elastomer 26 is installed on the opposite of the elastomer 26 of the conductor 20. The elastomer 26 comprises rubber containing a specified amount of a conductive material as to provide conductivity when compressed. In this way, a connector of an interval density of 0.025cm and low height and not necessary to be soldered can be obtained.

Abstract: PURPOSE: To facilitate correction and diffusion by constituting from plural storing node means connected in tree structure or allow each storing node means to store a code describing at least one consecutive and equal data elements. CONSTITUTION: In data, the consecutive and equal data elements are identified as LAN and each LAN is described by a code consisting of the count of the number of the data elements in LAN and one data element expressing the data element in LAN. These codes are stored in a storage node to store other codes such as a starting index to the data element in LAN. The storage node is provided successively in three structure by first and second links. When a specific LAN is specified to be the LAN of the present storage node, the first like shows a storage node storing LAN before present LAN and the second link shows a storage node storing LAN following present LAN. Thus, at the time of storing data in regression LAN array, data is efficiently stored, searched, corrected and diffused.

Abstract: PURPOSE: To make it possible to selectively execute plural arithmetic operations in parallel by providing a central processor with a set of dedicated arithmetic instructions for executing a narrow gauge instruction. CONSTITUTION: A CPU 10 consists of 4 independent processors 12a to 12d sharing the access to an instruction cache 14, a data cache 16, a memory control unit 18, and a memory/bus interface 20. Further, each of 'parallel addition', 'partial subtraction' and 'partial comparison' instructions executes arithmetic operation for bytes or half words where two operands are corresponding to each other, and returns the result in unit of byte or half word to the processor. The partial multiplication instruction multiplies a multiplicand in unit of byte or half word by a common multiplier, and returns the product in unit of byte or half word to the processor, and the carry condition codes are individually maintained for each half word or each byte. The partial carry load instruction code extends the carry condition codes to each half word or byte. Thereby, multigauge arithmetic operations can be executed at high speed.

Abstract: PURPOSE: To prevent the generation of a color artifact by using auxiliary notch filters including notch filters for filtering a keying signal at the time of converting R/G/B signals into a composite video signal. CONSTITUTION: A 1st converter 20 converts a composite video signal into 2nd R/G/B signals. A 2nd converter 32 converts 1st R/G/B signals into a composite overlay signal by using notch filters 37, 38 for filtering a luminance signal in a conversion process. Combination is executed by both of 1st and 2nd switches 22, 33. The 1st switch 22 selects either one of the 1st R/G/B signals and the 2nd R/G/B signals under the control of a keying signal. The 2nd switch 33 selects the composite video signal or the composite overlay signal by using a keying signal filtered by the notch filters 37, 38.

Abstract: PURPOSE: To compactly store data by condensing the bit map of information into 1st binary state and coding the condensed bit map. CONSTITUTION: As the main process of algorithm, the bit map of a video image is condensed to zero and the condensed image is coded to series of zero and data bytes. The video image is condensed to zero by autocorrelating (shifting and exclusively ORing) horizontal and vertical lines. The number of zero provided from respective correlations is counted until it is determined which combination generates the most condensed zero. Afterwards, the bit map of a line condensed to zero is coded to series of zero and data bytes. Thus, the number of bits to be physically stored for storing the video image can be decreased.
