摘要:
In a semiconductor device wherein a bonding pad is formed on an electrode through an insulating interlayer and a bonding wire is bonded to the bonding pad by thermocompression bonding, a through hole for connecting the bonding pad and the electrode is formed in the insulating interlayer above a contact hole for connecting the electrode and an active region formed in a semiconductor substrate. Metal columns of members of the electrode filled in the contact hole and members of the bonding pad filled in the through hole are formed under the bonding pad.

A compound of the formula: ##STR1## wherein R is NH.sub.2 or NO.sub.2, and X is chlorine or bromine, is disclosed. These compounds are useful as intermediates in the production of herbicidal tetrahydrophthalimides of the formula: ##STR2## wherein R' is a C.sub.3 -C.sub.4 alkenyl group or a C.sub.3 -C.sub.4 alkynyl group, and X is as defined above.
摘要:
A desensitizing gum comprising an aqueous solution of water-soluble and film-forming hydroxyalkylated starch, characterized in that the degree of etherification of the hydroxyalkylated starch is 0.03 to 0.08 and the gum further contains at least one member selected from the group consisting of anionic and nonionic surfactants.
摘要:
A desensitizing gum for a lithographic printing plate and a gumming up process thereof are disclosed. The gum is comprised of water having dispersed therein 5 to 35 wt %, based on the total weight of the gum, of a film-forming, water-soluble compound selected from the group consisting of enzyme-decomposed dextrine and enzyme-decomposed etherified dextrine. The desensitizing gum exerts a desensitizing action on non-image areas of a lithographic printing plate and does not cause image blinding of image areas even when the plate is stored for a long period of time.

A structure having a shaft and a paper retaining roller mounted on the shaft for use in a printer. The structure further includes a retaining element mounted on the shaft so as to be opposed to the roller for retaining the roller in a given axial position on the shaft. The roller is rotatable about the shaft and has a flange at its one end. The retaining element has a plurality of resilient retaining arms and its one end to hold the flange rotatably. At the opposite end, the retaining element is also provided with a plurality of resilient arms which are in frictional engagement with the outer periphery of the shaft. The roller can be slid axially along the shaft when a force greater than a given magnitude is applied thereto.
