摘要:
In a conventional polymer membrane electrode assembly, particularly when operated for a long period of time, a portion of the polymer electrolyte membrane to be in contact with the gas diffusion layer has suffered significant degradation. In order to address this, in a membrane electrode assembly including a hydrogen ion conductive polymer electrolyte membrane, a pair of catalyst layers arranged on both surfaces of the polymer electrolyte membrane, and a pair of gas diffusion layers, each including a fibrous substrate, arranged on the outer surfaces of the catalyst layers, a thickness TA of a center portion that faces the catalyst layer and a thickness TB of a peripheral portion surrounding the center portion are set to satisfy a expression (1): 0.7≦TB/TA≦0.9.

Received electronic mail includes a text code and a pictographic character code, for example. A non-stereoscopic process is performed on an image of characters by the text code, and a stereoscopic process is performed on an image of a pictographic character by the pictographic character code. The stereoscopic process allows a viewer to observe a pictographic character representing a car LP shifted to left (shown with a dotted line) through the parallax barrier only with the right eye R, and to observe the pictographic character representing a car RP shifted to right (shown with a dotted line) through the parallax barrier only with the left eye L. Accordingly, the viewer perceives (stereoscopically views) the pictographic character representing a car at a position as if to be protruding from a display surface. Therefore, all the characters in a text are not simply stereoscopically displayed but the pictographic character, and the like, is stereoscopically viewed overlapped on characters to be non-stereoscopically viewed.

An object of the present invention is to realize an in-home network system that is capable of smoothly controlling an appliance even when a new kind of appliance that has not been obtained conventionally is connected to an in-home network or even when an unusual, special use form is set in a network. A controller of the present invention compares a device type of an appliance connected to an in-home network with a skeleton stored in a skeleton DB. When a skeleton rule in accordance with the appliance type is not stored in the skeleton DB, a request for acquisition of the skeleton rule of the appliance is transmitted to a service agent. In addition, when the location of an appliance is moved, the controller sends a request for transmission of a new rule format to be added due to the movement to the service agent.

The present invention provides a membrane-electrode assembly for polymer electrolyte fuel cells and a polymer electrolyte fuel cell having excellent dimensional stability and mechanical strength, and having high durability at the time of a power generation. Each of polymer electrolyte membranes (111, 211, 311) have a region 1 having proton conductivity over the entirety in the thickness direction of the membrane and a region 2 located at the outer peripheral portion of the region 1 and having a non-porous sheet disposed so that the region 2 has no proton conductivity over the entirety in the thickness direction of the membrane, and outer edges of the catalyst layers (127, 128) are disposed so as to be located in the area 2.

A magneto-optical record medium and a reproducing apparatus for the same allow data reproduction having good characteristics by a simple structure. The magneto-optical record medium includes a plurality of first grooves (3) each having sidewalls, at least one of which is wobbled in accordance with address information; an address mark (21) formed by changing a width of a land located between second grooves connected to the first grooves; and third grooves wobbled cyclically, formed in a data portion magnetically storing data and connected to the second grooves. The reproducing apparatus reproduces the data from the magneto-optical record medium.

A meandering groove is formed in a digital disk (10) with a wobble signal that is wobbled to reproduce a clock signal. The wobble signal is read out by an optical head (26). An address detection circuit (40) detects an address signal that is multiplexed with the wobble signal. A PLL oscillation circuit (24) provides a clock signal in synchronization with the wobble signal. Data is modulated by a modulation circuit (16) according to the clock signal and a timing signal based on the address signal, and recorded on the digital disk (10). In reproduction, a RF signal in the wobble signal is converted into a digital signal by an A/D converter (42). The signal is demodulated by a demodulation circuit (44) for data output.

摘要:
In a field effect transistor (JFET) having a compound semiconducting substrate, a buffer layer having a guard-ring, an active layer, source regions, drain regions, and gate regions, the guard-ring is separated from the active layer whereby gate junction capacitance and gate leakage current are lowered without raising a gate resistance value. As a result, noise characteristics and high frequency characteristics can be improved.

Upon a license-data transmitter verifying a certificate C[KPdx] (the license-data receiver and the license-data transmitter will be referred to as “x” and “y”, respectively), the license-data transmitter transmits challenge information Ep(KPdx, Kcy) to the license-data receiver. In response to the challenge information, the license-data receiver transmits session information Es(Kcy, Ksx//KPpy) to the license-data transmitter. The license-data transmitter provides encrypted license data Es(Ksx, Ep(KPpx, LIC)) in a form encrypted using these two keys Ksx and KPpx thus received. With the cryptosystem according to the present invention employing EC-DH as the public key cryptosystem, the transmitter provides the second or subsequent license data without transmission of the challenge information and without updating the shared key.
摘要:
A license-data transmitter (in a case of recording, a recording device 100 serves as a license-data transmitter, and in a case of readout, a storage device 200 serves as a license-data transmitter) verifies a certificate C[KPdx] (the license-data receiver and the license-data transmitter will be represented by “x” and “y”, respectively) of a license-data receiver (in a case of recording, a storage device 200 serves as a license-data receiver, and in a case of readout, a reproducing device 300 serves as a license-data receiver), following which the license-data transmitter transmits a certificate C[KPdy] thereof to the license-data receiver in the form of challenge information E(KPdx, Kcy)//C[KPdy]. Then, the license-data receiver verifies the certificate C[KPdy] of the license-data transmitter. Only in a case that the license-data transmitter device has been authorized, the license-data receiver transmits the session information E(Kcy, E(KPdy, Ksx)//KPpx) to the license-data transmitter in response to the challenge information. The license-data transmitter provides the license data to the license-data receiver using the key Ksx and KPpx thus received.
