摘要:
A wire bonding method for bonding a first bonding point and then a second bonding point by bonding wire that passes through a capillary including a reverse operation that moves the capillary in a direction opposite from a second bonding point after the bonding is done to the first bonding point, a damper is closed temporarily during the reverse operation so as to apply tension to the wire, thus forming a strong kink at an uppermost point of the neck height portion of a resulting wire loop between the first and second bonding points.

For facilitating and making more efficient the setting of the operating parameters of a bonding tool that is used to form a wire loop into a desired shape, when an editing handle is dragged, the loop shape of a wire loop line drawing displayed on a display screen is redrawn as a secondary loop line drawing. The values of the operating parameters corresponding to the loop shape of the drawn or redrawn secondary loop line drawing are calculated, and the results are displayed in a parameter list.

Water-absorbent resins having an average particle diameter of 100 to 600 .mu.m and a particle diameter distribution of 0.35 or less are prepared by polymerizing an aqueous solution of a water-soluble ethylenically unsaturated monomer, pulverizing and sieving the gel-like polymer so obtained, and crosslinking the surface of the polymer powder. In an alternative process, an aqueous solution of the monomer having a viscosity greater than 15 cps is dispersed in a hydrophobic organic solvent and polymerized to obtain a polymer powder, and the surface of the polymer powder is crosslinked.

摘要:
A touch panel input apparatus has a touch panel which consists of X- and Y-direction electrode panels. When the apparatus is in a power-off state, one end of the X electrode panel is intermittently connected to a power source and one end of the Y electrode panel is intermittently grounded via an output resistor, in response to control signals outputted from a sampling circuit. In this state, synchronously with a clock signal, the sampling circuit performs sampling of a voltage developed across the output resistor when the two electrode panels are brought into contact. The sampling circuit outputs a power-on instruction signal to make the CPU perform the power-on operation. The sampling circuit stops its sampling operation once power is turned on.

摘要:
A process for producing a modified polyaminoamide with markedly increased reactivity as an epoxy resin curing agent is disclosed. The process comprises introducing amino groups and mercapto groups into a polyaminoamide by using an aziridine compound and a thiirane compound. The modified polyaminoamide is capable of curing an epoxy resin at a low temperature and at a high rate to provide a cured epoxy resin excellent in anticorrosion and chemical resistance.
