摘要:
The semiconductor integrated circuit enjoys a high performance and can be produced at a low production cost and within a short time. A cell has an internal circuit connection such that an output terminal is connected to a plurality of input terminals through source-drain paths of active devices connected in the tree form, and gate electrodes of the active devices are connected to other input terminals. Two such cells having the same internal circuit connection, the same disposition of the internal circuit devices and the same disposition of the input/output terminals are disposed on the same chip, and mutually different logics can be accomplished by changing the form of application of input signals from outside the cells to the input terminals. A chip area of an integrated circuit designed by CAD using a cell library can be reduced and a high speed circuit operation can be attained. The present invention provides remarkable effect for improving performance of an ASIC, a microprocessor, etc., and for reducing the cost of production.

For the relation between the first and second pass-transistor circuits (PT1, PT2), the output signal of the preceding-stage is supplied to the gate of the succeeding-stage, and for the relation between the second and third pass-transistor circuits (PT2, PT3), the output signal of the preceding-stage is supplied to the source-drain path of the succeeding-stage. The first pass-transistor circuit (PT1) receives on its first input node (In1) and second input node (In2) the first input signal and the second input signal that are logically independent from each other. This logic circuit requires a smaller number of transistors and is capable of reducing the power consumption and delay and accomplishing an intricate logic function.

In order to effectively explore a binary decision diagram for synthesizing a logic circuit, a tentative circuit comprised of AND gates and OR gates is synthesized from a logic function. The number of gates in this circuit to which two input variables are simultaneously associated are counted and used as correlation between the two input variables. A correlation matrix for correlation among all of the input variables is generated. The input variables are sequentially grouped from a set of input variables with strongest correlation in the correlation matrix: These groups are registered into a correlation tree, and an intergroup correlation tree is produced. These groups are sequentially selected from a group with the least correlation, and the intragroup order of the selected group is changed from one to another. A binary decision diagram is explored which satisfies the most appropriate condition in that group (such as the minimum number of nodes, the minimum delay, and the minimum area). The above processes repeated for all groups. Each node of the binary decision diagram thus obtained is substituted by a selector and each selector circuit is substituted by a circuit of a transistor level.

摘要:
The present invention provides an impaction-based microorganism collecting device in which microorganisms are captured by the capture surface of a collection plate. The microorganism collecting device is designed to reduce the influence of the lateral wind flowing over the perforated plate having multiple nozzles and also prevent warpage of the perforated plate.Multiple air vents are formed around the circumference of the capture surface and through the capture surface so that air that has flowed through the nozzles of the perforated plate onto the capture surface can be discharged. This allows the air to flow in multiple directions over the capture surface, thereby reducing the speed of the air and increasing the microorganism capture rate.

The invention provides an analgesic anti-inflammatory patch of a hydrophobic type for topical application containing, in a Pressure Sensitive Adhesive(PSA), diclofenac sodium, pyrrolidone or a derivative thereof, a polyhydric alcohol fatty acid ester, and an organic acid. The patch exerts the following effects: (1) diclofenac sodium is effectively and continuously released from a Pressure Sensitive Adhesive(PSA) and percutaneously absorbed, thereby attaining sustained, excellent pharmaceutical and pharmacological effects; (2) the patch per se has high tackiness and safety; and (3) diclofenac sodium remains stable in the Pressure Sensitive Adhesive(PSA).
