Title: Automatic mat border sewing device and automatic sewing and cutting device for mat border and base
Inventor: INOUE HIROBUMI
IPC: B26D1/04
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To manufacture a mat (Japanese tatami) with high accuracy in shape by mounting a color sensor for detecting a reference line of a cutting edge of a mat facing, and properly sewing a mat border to a mat base on a position inside of a cutting edge of the mat facing by a specific length on the basis of the information detected by this sensor. SOLUTION: When a color sensor 27 is moved on a cutting line (s) on a mat facing (w1) by the movement of a cutting and sewing head, and detects a color phase (mixture of color phase of mat base (w) and color phase (w1) of mat facing) different from the color phase of an upper surface of the mat base (w), an electronic switch circuit device compares the information detected on this occasion with the information stored in advance, judges the immediate stop of the cutting and sewing head, and transmits the switch output corresponding to the judgement. Whereby the motor stops its motion. The motor is stopped until the color sensor 27 detects the color phase of the upper surface of the mat base (w) or the color phase of the upper surface of the mat facing (w1), and the lateral movement of the cutting and sewing head is stopped.

Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To enable the assemblage of an optical system by using the adjusting method of lens position for ensuring the performance by assembling it after adjusting the position of a lens block so that the one-side blurring amounts of off-axis light beams in more than two directions become minimum. SOLUTION: The one-side blurring amounts of off-axis light beams in more than two directions are detected from a light ray transmitted through a part or a whole of an optical system and, after adjusting the position of a lens block composed of a single or plural lenses in the optical system so as to minimize the one-side blurring amount, the lens block to be adjusted is fixed/ assembled. In this case, as to the directions in which the off-axis light beams are detected, two directions in the longitudinal direction are enough when the format of an image forming surface is laterally long but detection in more than four directions are indispensable when the format is close to a square, for example, like a silver chloride camera and a digital camera. Consequently, a very compact optical system, from which one side blur is removed, having a whole image plane of good performance is provided.

Title: Method of echo cancellation and subscriber line audio processing circuit
Inventor: KANAN PII BAIRABAN
IPC: H04B3/23
Filed: 1988-10-01
Abstract: PURPOSE: To achieve a substantially improved learning curve by updating an adaptive digital filter coefficient corresponding to nonlinear signal algorithm. CONSTITUTION: The utilization of CSD updating algorithm is especially suitable for an adaptive filter 10 and it is because it depends on only the code of the product of Xn and En decided by an exclusive OR function. An error En is equal to input signals dn first and the error En is reduced as the filter 10 is adapted to a specified line state and finally becomes close to a residual limit. When the filter is adapted, residual errors fluctuate near a small value. Thus, in simulated adaptation for utilizing present color noise as input Xn and utilizing the CSD updating algorithm to the coefficient of the filter 10, convergence to the residual limit is obtained within about 5000 repetition.

IPC: D05B51/00
Filed: 1992-09-18
Abstract: PURPOSE:To prevent the lowering of the quality of embroidery caused by yarn breakage as far as possible and minimize the deterioration of the operation efficiency. CONSTITUTION:When a yarn breakage is detected by a yarn breakage sensor (S21: Yes), the driving of the machine head having the yarn breakage is stopped by a controller (S22) and the yarn-breakage generation position in the embroidery data of the machine head and the number of the machine head are stored in a RAM (S23). An operator specifies (S27), with a keyboard, a machine head to restart the embroidery work of a cloth to which the embroidery work is interrupted by the yarn breakage. Each embroidery cloth subjected to the interruption of embroidery work is set on each machine head and embroidery work is restarted. The drive-starting timing of each machine head for each embroidering cloth having different yarn breakage position is controlled by this process to enable the restart of the embroidery work corresponding to the yarn breakage generation position.

Title: Manufacture of dbc board
Inventor: YOSHINO HIDEYUKI
IPC: C04B37/02
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To dispense with a removal operation through which Cu2 O is removed from an Mo mesh, so as to lessen a product in manufacturing cost by a method, wherein a resin layer which is decomposed at temperatures higher than a pre- oxidizing temperature but lower than a bonding temperature previously formed on a non-bonding surface before a pre-oxidation treatment is carried out. SOLUTION: A resin layer 10 is formed on a part of a Cu board 25 which is not bonded to a ceramic board or comes into contact with Mo meshes in a resin layer forming process. Usually, the Cu board 25 of OFC is subjected to a pre-oxidation treatment at a temperature of 250 to 300 deg.C, and the ceramic board and the Cu board 25 are DBC-bonded together at a temperature above 1000 deg.C. Therefore, it is preferable that resin does not decompose at a pre- oxidation treatment but is quickly decomposed and dissipated in a DBC bonding process, so that acrylic resin, polybutene resin or polyether resin that meets the above requirements is suitable as the resin material, taking its handling properties and stability into consideration, when the resin turns into liquid.
