Title: Method for preventing surface curing of moisture-curable contents
Inventor: IZUMI KATSUYUKI
IPC: C08G18/08
Filed: 1991-10-29
Abstract: PURPOSE:To prevent end NCO group-containing moisture curable contents from causing surface curing in the case of flow of air into a container by reacting the contents in the container with a specific compound to make the contents moisture incurable. CONSTITUTION:In putting end NCO group-containing moisture curable contents in a container in which a middle cover is placed on the contents and an opening part of the container is closed with an external cover, the end NCO group in the contents is reacted with a reactive monofunctional group-containing compound (e.g. monohydric alcohol) and the NCO group on the surface of the moisture-curable contents is deactivated and the contents are made moisture- incurable. To be concrete, for example, the surface of the contents in the circumference of the middle cover is coated with the reactive monofunctional group- containing compound by spray or the reactive monofunctional group-containing compound is impregnated into the middle cover made of felt and reacted with the moisture-curable contents. For example, an end NCO-containing urethane prepolymer is used as the contents.

IPC: H03H7/20
Filed: 1989-10-31
Abstract: PURPOSE:To eliminate a need of a transformer by outputting the in-phase output and the anti-phase output of a clock signal by a gate circuit. CONSTITUTION:The clock signal inputted to a signal input terminal 1 is inputted to a gate circuit 2, and the in-phase output and the anti-phase output are outputted from this circuit 2. One output passes a variable resistance 4 and the other passes a capacitor 5, and they are added and are outputted from a signal output terminal 6. At this time, the sum of these two signals is taken to convert signals to a vector sum; and when the resistance value of the variable resistance 4 is changed, the vector sum is changed to output the signal, which has the phase changed, from the signal output terminal 6. Thus, a transformer to get the in-phase output and the anti-phase output is unnecessary to reduce the scale and the weight of the circuit.

The binarization of the cell image is performed by setting specified density as a threshold value, making a pixel having density larger than the threshold value a black pixel, and making a pixel having density smaller than the threshold value a white pixel. In order to determine the threshold value, the average value of the peak densities of a bright part and a dark part of a histogram indicating number of pixels with respect to the density of picked-up cell pixels is set as he threshold value.  Imperfect cell mesh point in the defective state on the end edge of the cell image for which binarization is ended are all eliminated. The area of a plurality of perfect cell mesh points is calculated, and a cell area ratio is calculated.
