Title: Device for applying adhesive
Inventor: ARUFUREETO DETSUTERUBATSUHA
IPC: B05C11/10
Filed: 1982-04-12
Abstract: The applicator for applying adhesive to a work piece, for example in an edge glueing machine for work pieces moving continuously through the machine, has adhesive discharge holes (6). The adhesive is supplied through these holes (6) under pressure to the edge of work pieces. Any contaminating particles, which may be present in the adhesive prior to its application to the work piece, tend to travel upwardly with the adhesive in the adhesive supply conduit (2, 4), due to their lower specific weight, whereby the contaminations may clog the discharge holes (6) and prevent the proper application of adhesive to a work piece. For avoiding such clogging the nozzle body (1) is provided with a scavenging duct (5) which is connectable to the adhesive supply conduit (2, 4) for repeatedly passing a portion of adhesive out of the supply conduit (4), whereby the application of adhesive may be performed without any trouble. The discharge holes (6) are closed during the scavenging of a small portion of adhesive. Preferably the scavenging duct portion (5') is connected to the supply conduit at a location above the adhesive discharge holes (6).

Filed: 1996-02-24
Abstract: PROBLEM TO BE SOLVED: To evaluate damage intensity or a slip resistant dislocation intensity based on the measurement of the stress-strain characteristic of a wager itself to which a skew layer is guided by executing evaluation based on the degree of deterioration on an upper yield stress value and a lower yield stress value in the stress-strain characteristic. SOLUTION: The intensity of the semiconductor wafer having the strained layer which is intentionally guided from outside on one main face where the device of the semiconductor wafer is not formed is evaluated based on the degree of deterioration on the upper yield stress value MP1 and the lower yield stress value MP2 in the stress-strain characteristic being the mechanical intensity characteristic of the semiconductor wafer. A satisfactory correlation exists between the deterioration quantity of the upper yield stress value MP1 of the semiconductor wafer which the stained layer is guided by a lapping method and slip dislocation defect guide quantity.  When the upper yield stress value of the wafer having the strained layer which is intentionally guided from outside is within the range of 90 to 100% compared to a case when the external strain does not exist, satisfactory slip resistant intensity is shown.
