摘要： A diisopropylnaphthalene mixture containing 50% or more of 2,7-isomer is substantially odorless, has a low viscosity and exhibits a high dissolving power particularly for an electron-donating color former including a black color former. By coating of micro-capsules of an ink comprising the solvent and a color former on a substrate, a carbonless copying paper which is odorless and excellent in color developing speed including that at lower temperatures, can be obtained.

摘要： Two intermediate potentials of small current driving capacity are generated using load elements and MOS transistors, and are respectively supplied to the gates of two MOS transistors which are series-connected between power sources and have large current driving capacity, thus obtaining an intermediate potential from a node between the MOS transistors. The MOS transistors at the output stage are complementarily operated so as not to be turned on at the same time.

摘要： An electromagnetic cortical stimulation array structured to stimulate cortical regions during a presurgical localization of eloquent areas. The device includes array of miniature elongated magnetic coils (optionally overlaid on an array of electrodes) oriented substantially parallel to one another and structured to be inserted under the dura during an open cranial neurosurgery. Each coil and electrode is activated (optionally, selectively) to subdurally stimulate different regions of the cortex to determine functions of each cortical area.
