摘要:
In the inventive fabrication process for electrodes for electrochemical devices, when the coating film is rolled so as to increase its density, the given binder solvent is intentionally allowed to remain in an amount good enough to keep pores on the surface of the active substance uncrushed, and after the rolling operation is carried out, the solvent extraction operation is conducted to remove the binder solvent remaining in the pores in the coating film. Thus, an electrochemical device using an electrode according to the inventive fabrication process is much improved in electrostatic capacity as well as in durability and reliability as well.

An exhaust gas-purifying catalyst includes a support provided with one or more through-holes through which exhaust gas flows, and a catalytic layer supported by the support and containing an oxygen storage material. The exhaust gas-purifying catalyst includes a first section to which the exhaust gas is supplied, and a second section to which the exhaust gas having passed through the first section is supplied. The catalytic layer includes a layered structure of a first catalytic layer containing platinum and/or palladium and a second catalytic layer containing rhodium in the first catalytic section and further includes a third layer containing rhodium in the second section. The second section is smaller in oxygen storage material content per unit volumetric capacity than the first section.

A voice recognition unit is constructed in such a way as to create a voice label string for an inputted voice uttered by a user inputted for each language on the basis of a feature vector time series of the inputted voice uttered by the user and data about a sound standard model, and register the voice label string into a voice label memory 2 while automatically switching among languages for a sound standard model memory 1 used to create the voice label string, and automatically switching among the languages for the voice label memory 2 for holding the created voice label string by using a first language switching unit SW1 and a second language switching unit SW2.
摘要:
A client (such as a PC, portable telephone, PDA, electrical appliances), to which a device such as a IC card is connected, starts a handshake protocol to request a server to start communication. When communication is established via the handshake protocol, the initiative of communication is transferred to the server, and the state changes into a neutral state. In this neutral state, a control packet including a particular number of messages and a finished message is transmitted from the server to the client. If the client receives the control packet, the client performs a process according to the messages included in the control packet. This makes it possible to remotely control a device via a network in a highly reliable and efficient manner.

An image processing apparatus is provided. A density conversion component converts a density of a transparent color material so that a total amount of a plurality of color materials is smaller than a predetermined first amount when it is determined that the total amount of the plurality of color materials is larger than the predetermined first amount and when the transparent color material is included in the plurality of color materials. A density ratio calculation component calculates a ratio between a density before converting the density of the transparent color material and a density after converting the density of the transparent material. A reporting component reports that the ratio of the density is smaller than a predetermined second amount when determining that the ratio of the density is smaller than the predetermined second amount.
摘要:
An exhaust gas purification catalyst includes: a lower catalyst layer that contains a ceria-zirconia mixed oxide having 50 to 70 mass % of CeO2 and 5 mass % or more of Pr2O3 and carries at least one of Pt and Pd; and an upper catalyst layer that contains at least zirconia and carries at least Rh, wherein the total amount of CeO2 per liter of the carrier base is 15 to 30 g. Because the amount of CeO2 is small, formation of H2S is suppressed and a high capability of adsorbing and releasing oxygen is brought out in spite of the small amount of CeO2.

The composite particle for an electrode in accordance with the present invention contains an electrode active material, a conductive auxiliary agent having an electronic conductivity, and an oxidizing/reducing agent. Therefore, this composite particle can construct an effective conductive network, and effectively provide so-called oxidizing/reducing capacity due to the oxidizing/reducing agent. Hence, when the composite particle for an electrode in accordance with the present invention is used as a constituent material of an electrode in an electrochemical device, the electrochemical device can realize a higher capacity.
