摘要:
By using a gas diffusion layer for a fuel cell comprising a fabric comprising a warp thread and a weft thread which are made of carbon fiber, wherein the distance X between adjacent intersections where the warp and weft threads cross each other and the thickness Y of the fabric satisfy the equation: 1.4≦X/Y≦3.5, the present invention reduces the surface asperities of the substrate and prevents a micro short-circuit resulting from the piercing of the polymer electrolyte membrane of the fuel cell by the carbon fibers of the fabric so as to improve the characteristics of the fuel cell. In order to further prevent the piercing of the polymer electrolyte membrane by the carbon fibers of the gas diffusion layer substrate, the rough surface of the carbon fabric is smoothed by: (1) applying a clamping pressure of 1 to 20 kgf/cm2 to the contact area between each electrode and each conductive separator plate of the fuel cell; or (2) heating the gas diffusion layer surface before the gas diffusion layer is disposed onto the polymer electrolyte membrane.

A polymer electrolyte fuel cell comprising an anode, a cathode, a polymer electrolyte membrane interposed between the anode and the cathode, an anode-side separator plate having a gas flow path to supply fuel gas to the anode and a cathode-side separator plate having a gas flow path to supply oxidant gas to the cathode. Each of the anode and the cathode comprises a catalyst layer in contact with the polymer electrolyte membrane, an electrode supporting material having gas permeability and electronic conductivity, and a water repellent layer interposed between the catalyst layer and the electrode supporting material. The water repellent layer has through holes through which the catalyst layer and the electrode supporting material are electrically connected.

A recording device according to the present invention has a function (202, 206, 207) of dividing precoded record data into data blocks of a prescribed length to adjust to a magneto-optical disk (3) and adding an intrinsic pattern before and after the data blocks. As the intrinsic pattern, a pattern which reduces a decoding error of maximum likelihood decoding at an end of each data block is used. Therefore, even when data is inserted after preceding, code correlation of a precoded signal can be maintained at a location where division is performed.

In an inter-processor data transfer system between first and second processors, a first FIFO is provided for data transmitted from the first processor to be written therein, and a first register is provided for indicating whether the first FIFO is write-enabled or write-disabled. A first request circuit transmits a write-request from the first processor to the second processor by way of the first FIFO. A first notification circuit notifies the first processor if data received by the second processor by way of the first FIFO is normal or abnormal. Also, a second FIFO is provided for data transmitted from the second processor to be written therein, and a second register is provided for indicating whether the second FIFO is write-enabled or write-disabled. A second request circuit transmits a write-request from the second processor to the first processor by way of the second FIFO. A second notification circuit notifies the second processor if data received by the first processor by way of the second FIFO is normal or abnormal.

In an SPC PBX, a frame bit is inserted at periodic intervals to each of time-slot sequences from output ports of a time switch to form primary rate frames and the frame bit is then removed from each primary rate frame, producing time-slot sequences which are multiplexed and framing bits are inserted to form an outgoing secondary rate frame for transmission. An incoming secondary rate frame is received and framing bits are removed therefrom and demultiplexed into incoming primary rate time-slot sequences. A frame bit is inserted to each of the incoming primary rate time-slot sequences and the frame bit is then removed before being supplied to input ports of the time switch. The frame bit insertion and removal allows the use of current design primary rate interfaces, so that secondary rate interfaces can be installed without altering the operating software of the switch.

摘要:
A deviation amount of a pictographic character portion of “G” is calculated based on a description of a file, and left eye-use display data (ABCDEF GIJK) and right eye-use display data (ABCDEG HIJKL) in a portion (b) in FIG. 3 are generated. A starting location of a description of “ABCDEFGHIJKL” is specified by an X coordinate and a Y coordinate described in the file. In addition, a process of alternately writing pixel data constituting the left eye-use display data (ABCDEF GIJK) and pixel data constituting the right eye-use display data (ABCDEG HIJKL) from a pixel data storing location of a VRAM corresponding to the coordinates (that is, one right eye-use pixel and one left eye-use pixel are alternately written one after another in a horizontal direction as a display image) is carried out.
摘要:
Confidential data such as license data is encrypted using the symmetric key encryption algorithm alone which requires smaller computation amount, and is readily realized by hardware elements, as compared with the public key encryption algorithm. A license-data transmitter (y) encrypts license data LIC using two keys Kscy and Kssx supplied from a license-data receiver (x). The license data is provided to the license-data receiver in the form of encrypted license data E(Kscy, E(Kssx, LIC)). This enables high-speed processing without deterioration in security even if data access such as recording/readout of data is repeated.
