摘要:
Novel process for biochemical optical resolution of 2DL-racemic compound of .alpha.-tocopherol ester or substances which contain the same, using culture broth, whole cell, or culture filtrate, which are obtained by cultivating microorganisms which possess an ability for hydrolysis of said ester. Beneficial advantage of the process resides in its low cost, simplicity and high resolution ratio.

In the semiconductor integrated circuit device provided with a plurality of second well regions of the same conductivity type, formed by dividing a first well region provided in the semiconductor substrate by an isolation trench, the isolation trench is substantially linear on the semiconductor substrate surface and the ends reach out of the first well region, however there is no intersection part, namely a corner part T part or cross part in the isolation trench. Therefore, no cavity occurs in the filler in the trench and stress is not concentrated on the intersection part. In addition, defects due to junction leak or mechanical damage do not occur, that is, there is no characteristic deterioration occuring. By providing the second well with memory cell, a semiconductor memory device whose characteristic defect rate and reliability defect rate are remarkably low can be formed.

Indirect blood pressure measurement for a systolic or diastolic blood pressure is accomplished by making use of a true Korotkov sound determination. When three or four Korotkov sound signals are found in four successive heart pulses of a body, each of the three or four Korotkov sound signals is determined as a true Korotkov sound signal. A cuff pressure existing when the first true Korotkov sound appears is determined as a systolic blood pressure. Another cuff pressure existing when the last true Korotkov sound signal appears is determined as a diastolic blood pressure. The last true Korotkov sound signal is determined by counting three heart pulses unaccompanied by no Korotkov sound signals following the detection of the last true Korotkov sound appearance.

In an integrated circuit package, a deformed IC lead is reliably connected with a land for mounting. Such reliable connection between the deformed IC lead and a land is realized by a method for mounting an integrated circuit package wherein a non deformed first lead and a deformed second lead in the integrated circuit package are connected to a first land and a second land on a substrate, respectively. comprising a step for supplying a conductive material on a land wherein a larger amount of the conductive material than that of the first land is supplied to the second land; and a step for melting the conductive material supplied to connect a lead with a land wherein the conductive material molten on the first land extends in the vertical direction with respect to the substrate with a first height thereby connecting the first lead with the first land, while the conductive material molten on the second land extends with a higher second height than the first height due to surface tension thereby connecting the second lead with the second land.
摘要:
A writing high voltage of one polarity or an erasing high voltage of another polarity is selectively fed, in accordance with a writing or erasing operation mode, via a switch MOSFET to the word line of a non-volatile memory element designated by an address signal. The potential of a well region, where the switch MOSFET is existent, is changed in conformity with the switching action of the relevant switch MOSFET so as to control the switch MOSFET. Due to this arrangement, the potential of the well region with the non-volatile memory elements existing thereon can be retained at a fixed value, so that the high voltage generator is required merely to drive the selected word line of the memory array (and not the well in which the memory elements are formed). Consequently, the requisite current supply capability of the high voltage generator can be diminished.

Tissue plasminogen activator analogs exhibiting greater specificity for fibrin than native t-PA are disclosed. The analogs include the K1 domain of native t-PA replaced with another kringle domain mediating the binding of the analog to fibrin. The kringle contains six cysteine residues. The t-PA analogs may further include a variety of substitutions and modifications. Pharmaceutical compositions containing one or more of the t-PA analogs along with a physiologically acceptable carrier or diluent are also disclosed.
