The present invention provides a liver preservation solution containing trehalose and dibutyryl-cAMP. The content of nitroglycerin in the preservation solution is preferably lower than 0.44 mM. In the liver preservation solution of the present invention, since the toxicity due to nitroglycerin, which is observed during liver preservation, has been improved, liver transplantation can be performed with a high engrafted rate.

A conductive paste for forming a solar cell electrode, including: a conductive powder containing silver as a main component; glass frit; and an organic vehicle, wherein the glass frit contains tellurium glass frit having tellurium oxide as a network-forming component. The conductive paste of the present invention makes it possible to form a solar cell electrode having a low dependence on firing temperature without causing problems due to fire-through into the substrate, and to thereby obtain a solar cell having good solar cell characteristics.

Sequential digital audio signals are received to calculate a difference between each currently sampled digital audio signal and another digital audio signal sampled at one sampling period before each currently sampled digital audio signal. Differences for the sequential digital audio signals are stored. The number of digital audio signals consecutively clipped is counted in the received sequential digital audio signals. A specific difference is retrieved, from the stored differences, for a digital audio signal sampled at a specific number of sampling periods before each clipped digital audio signal. The specific number of sampling periods is determined based on the counted number of digital audio signals consecutively clipped. Each clipped digital audio signal is corrected based on the specific difference.
摘要:
A method for manufacturing a highly-crystallized oxide powder, wherein an oxide powder is produced by ejecting a starting material powder containing at least one metal element and/or semimetal element, which will become a constituent component of the oxide, into a reaction vessel together with a carrier gas through a nozzle; and heating the starting material powder at a temperature higher than the decomposition temperature or reaction temperature thereof and not lower than (Tm/2)° C., where Tm° C. stands for a melting point of the oxide, in a state in which the starting material powder is dispersed in a gas phase at a concentration of not higher than 10 g/L. In the above method, the starting material powder may be mixed and dispersed in the carrier gas by using a dispersing machine prior to being ejected into the reaction vessel through a nozzle. The resultant oxide powder has a high crystallinity, a high dispersibility, and a uniform particle size, without introducing impurities thereinto, by a low-cost and simple production equipment.

A data conversion device is provided with a data converting means that sequentially converts first data into second data of the number of second bits, wherein an analog signal is quantized into the first data by the number of first bits, and the first and second data can be first and second maximum values, respectively. The data converting means is comprised of a first conversion means (steps 21 and 23) that, when a value of the fast data is not the first maximum value, converts the first data to the second data by adding 0 to a lower bit side of the first data and a second conversion means (steps 21 and 24-26) that converts the first data to the second data so that, when a value of the first data is the fast maximum value, a value can be made larger, in accordance with a value be-fore or after the first data, than the data of the number of second bits obtained by adding 0 to the lower bit side of the first data. With the structure, when the data obtained by quantizing an analog signal is converted to data with the number of more bits, a rounding error by quantizing is improved as much as possible.
