Title: Method and equipment to wind up thread
Inventor: RORUFU HAAZEN
IPC: B65H63/00
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve the effect of a yarn end connection and to prevent a mis-shifting of work by ascertaining whether the yarn the yarn end is present in a take-up bobbin or not, and interrupting a command for rotating the take-up bobbin in a take-up direction for a short time if the present of the yearn end is detected. SOLUTION: A yarn 3 pulled out from a feed bobbin 2 passes through a yarn tensioning device 6, a yarn dust removing device 7, and the like. If the yarn dust removing device 7 detects the defect of the yarn, a cutting and tensioning 8 is operated, and during the cutting device 11 thereof cuts the yarn, a yarn end is fastened by a fastening device 12. The yarn end of the take-up bobbin 16 side is wound onto the take-up bobbin 16, and a sensor 49 detects whether the yarn end is on the take-up bobbin or not. If the present of the yarn end is detected, a command for rotating the take-up bobbin 16 in a take-up direction is interrupted. Therefore, the yarn end is easily aspirated into a suction nozzle 44, and winding-up onto the take-up bobbin is secured.

Title: Manufacture of laminated sheet
Inventor: TAKAMATSU SHOICHI
IPC: B29K105/24
Filed: 1985-10-31
Abstract: PURPOSE:To prevent in-stage components from slipping out strikingly decrease the difference in temperature between the center and the edge within a laminated sheet and consequently reduce the scattering in quality due to the temperature difference by a method wherein shape memory alloy is adopted on the whole or peripheral movable part of at least either one of a flat plate-shaped upper metal plate and a flat plate-shaped carrier plate so as to constitute vertical pieces to cover the side faces of the in-stage components during heating. CONSTITUTION:A carrier plate 11 made of shape memory alloy is set in the state that the plate 11 is flat under normal temperatures and vertical pieces, which cover the side faces of in-stage components, emerge when the plate 11 is heated. First, in-stage components 28 are placed onto the carrier plate 11 and capped with an upper ion plate 27. Secondly, when the in-stage components pinched between the upper iron plate and the carrier plate is heated under pressure with a multi-stage pressingly heated laminate molding press, the peripheral movable parts of the carrier plate bend themselves vertically with respect to the plane of the carrier plate due to the property of shape memory alloy so as to cover and closely contact the side faces of the upper iron plate. Thus, the gap between the upper iron plate 27 and the carrier plate 11 is eliminated and consequently the heat dissipation through the gap is prevented from developing and the heat quantity applied to the in-stage components becomes uniform within the surface of each component.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To properly correct the air-fuel ratio against the change of operating conditions by learning the deviation of the air-fuel ratio feedback correction quantity against the purge rate, and controlling the correction of the air-fuel ratio based on the learned value and the purge rate. SOLUTION: A purge valve passage area and a purge cut valve area are obtained (B1, B2). Since a purge valve and a purge cut valve are provided in series, the smaller area is selected as the purge passage area AP, and the actual purge rate PRATE is calculated from the purge passage area AP and total passage area AA (B3-4). The average of the air-fuel ratio feedback correction quantity α during the purge and the average of the air-fuel ratio feedback correction quantity α during the purge cut are obtained (B5-6). The deviation eα of the air-fuel ratio feedback correction quantity αis calculated, and the new gain G is calculated from the deviation eα and the actual purge rate PRATE (B7-8). The learned value of the gain G (gain leaned value) is allocated to a learning table for the region (purge gas flow).

Title: Image contour stressing processor
Inventor: MURASHITA MASARU
IPC: H04N7/18
Filed: 1990-09-14
Abstract: PURPOSE:To obtain an image contour stress processing which allows the setting of a contour for a contour stress processing freely by enabling the setting of an optional area desired for the contour stress processing on an image and a frame surrounding the area. CONSTITUTION:When sigma dispersion value sigma is compared with two reference dispersion values sigma1 and sigma2, a specified ultrasonic signal is transmitted to or received with an object 24 to be inspected from a probe 10 and an echo signal received is stored by one screen portion serial into a memory 12 as image information. Image density level information stored is outputted as a notice pixel value (z) and a means 2 in an area near pixels of Xn containing (z). But the dispersion value sigma is determined based on the means near the pixels of nXn in a specified area and a square mean. A comparison/computation circuit 18 compares the dispersion value sigma with two different reference values sigma1 and sigma2 predetermined and a pixel value stressing circuit 22 performs a contour stress processing to set the notice pixel value larger when the dispersion value is larger than the pixel mean and smaller when it is smaller than the mean. This enables the setting of a specified area alone thereby obtaining a pixel display state subjected to a proper contour stress processing.
