A full roll transferred from a cloth wind-up position in a weaving machine to a temporary full-roll storage position on a transfer carriage is prevented from rotation by meshing with a gear mounted stationarily. The transfer carriage is equipped with empty roll supporting arms and cutter supporting arms having free ends at which a cloth cutting mechanism is supported. An empty roll is supported by a holding device mounted at free ends of the empty roll supporting arms so as to be rotated by an empty roll driving motor. Owing to rotation of the empty roll, tension is applied to a cloth between the full roll and the empty roll so that it is cut by the cloth cutting mechanism in a tensioned stationary state.

In a chip reversing method for holding and vertically reversing a chip placed by a bonding nozzle, the chip is held on a chip holding unit disposed in a reversing member and is vertically reversed by turning the reversing member downward on an reversal shaft. After the reversed chip was received by a chip receiving unit, this chip receiving unit is lowered to a retracted position to return the reversing member to an original position. In this state, the chip receiving unit is raised to position the chip at a height level L for a chip transferring action. As a result, the reversing member does not protrude to above the height level for the chip transfer thereby to interfere with another mechanism, so that the chip mounting actions can be made efficient.

The present invention provides a method of forming a gate recess in an insulating film on a substrate for depositing a gate electrode film being in contact with a part of the substrate and also extending at least within the gate recess. The method comprises the steps of: forming an etching mask pattern with a first opening pattern on the insulating film; carrying out a first anisotropic etching process by use of the etching mask pattern at a first selective ratio of the etching mask pattern to the insulating film, thereby to form a first recessed portion having a bottom which lies at a first level higher than an interface level between the insulating film and the substrate; and carrying out a second anisotropic etching process by use of the etching mask pattern again at a second selective ratio of the etching mask pattern to the insulating film, wherein the second selective ratio is higher than the first selective ratio, thereby to form a gate recess which comprises a second recessed portion both having a bottom which lies at the interface level and having first side walls of a first oblique angle and a third recessed portion both having a bottom united with a top of the second recessed portion and having second side walls of a second oblique angle which is smaller than the first oblique angle.

Disclosed is a method of detecting a target base sequence having a polymorphic base, the method including: (a) a step of adding to a nucleic acid sample having a target nucleic acid that includes a base sequence including the target base sequence: at least one type of detection primer, at least one type of competitive primer, and at least one type of common primer; (b) a step of annealing the detection primer and the competitive primer to the target nucleic acid in a competitive manner, thereby synthesizing an extension product A; (c) a step of annealing the common primer to the extension product A obtained in the step (b) or in the following step (d), thereby synthesizing an extension product B; (d) a step of annealing the detection primer or the competitive primer to the extension product B obtained in the previous step (c), thereby synthesizing the extension product A; and (e) a step of detecting the extension product A or the extension product B.
摘要:
While a vicinity of a bottom surface-side region of a pressure-sensitive adhesive sheet, corresponding to an adhesion region of a semiconductor chip, is sucked and held, a plurality of protruding portions of a removing member are brought into contact with the bottom surface of the semiconductor chip through the adhesive sheet at the adhesion region. Also, the adhesive sheet is sucked in between the respective protruding portions so as to change an adhesive surface bond of the semiconductor chip to the adhesive sheet to point bonding. Further, the removing member is moved along the bottom surface of the semiconductor chip so as to change the position of the point bonding and decrease the adhesive bonding force to the adhesive sheet. Then, the semiconductor chip is removed from the adhesive sheet.

While a vicinity of a bottom surface-side region of a pressure-sensitive adhesive sheet (3) corresponding to an adhesion region (R1) of a semiconductor chip (1) are sucked and held, a plurality of protruding portions (30) of a removing member (21) are brought into contact with the bottom surface of the semiconductor chip through the adhesive sheet at the region. Also, the adhesive sheet is sucked in between the respective protruding portions so as to change a surface bonding of the semiconductor chip to the adhesive sheet by-adhesion to a point bonding, and further the removing member is moved along the bottom surface of the semiconductor chip so as to change a position of the point bonding and decrease bonding force to the adhesive sheet by the adhesion. Then, the semiconductor chip is removed from the adhesive sheet.
摘要:
A method of controlling operation of a loom machine by a computer equipped with a data input unit incorporating a display imparted with a function for generating a first list of weaving conditions at least for a weft insertion apparatus and a function for generating an alteration confirmation list when the conditions in the first list are altered. Upon inputting of data representing a desired fabric parameter, weaving conditions corresponding to the fabric parameter are selected from those previously stored in the computer, whereupon the selected weaving conditions are displayed in the first list. Before the selected weaving conditions are validated for controlling the loom operation, a confirmation list is again displayed for allowing the weaving conditions to be altered. When altered, the updated list containing the altered conditions is again generated for confirmation. When acknowledgement is input for the first list or the updated list, the corresponding weaving conditions in the list are transferred to a relevant controller. By generating the display for confirmation, alteration or change of the weaving conditions as desired can be reliably effectuated without suffering errors.
摘要:
A weft insertion control apparatus for a multi-color jet loom comprises a plurality of solenoid valves for controlling supply of a pressurized fluid to weft inserting auxiliary nozzles, an on/off controller for controlling these valves independently of one another, a first memory for storing a weft color selection pattern, and a second memory for storing on/off timing for the individual valves on a weft basis. The on/off controller reads out the weft color selection pattern stored in the first memory for every rotation of the loom and selects the preset on/off timing from the second memory on the basis of the result of the reading thereby controlling the valves.
