An object of the invention is to provide a method of forming a fine conductive pattern. The method allows the fine conductive pattern whose thickness is relatively large to be formed easily, accurately, and surely. An insulating layer is formed on a substrate. A pattern resist is formed on the insulating layer. Then, the insulating layer is etched downward based on a profile of the pattern resist in a first etching step, and sidewalls of each of groove portions formed by the etching step of the insulating layer are etched sideways in a second etching step, so that overhang portions are defined at the lower edges of the pattern resist portions. Then, conductive film portions are formed by depositing a conductor on the pattern resist, and conductive films that are on the pattern resist are lifted off, so that a fine conductor pattern can be prepared.

A resilient wave reducing structure which reduces waves propagating on liquid surface from propagating over the reducing structure and a method of constructing the wave reducing structure. The wave reducing structure of the present invention may be used to form a calm water surface region for harbors, for areas where construction work is being done or for areas where marine sports are to be performed etc. The resilient wave reducing structure includes at least one energy absorbing device having a resilient body constructed on a bottom of the liquid bounding the region where waves have to be reduced and filled with surrounding ambient liquid. This reduces the amplitude of waves passing over it by consuming the wave energy while it deforms according to the pressure distribution change caused by the waves and by radiating its kinetic energy into the liquid and the ground surrounding it. Because the wave reducing structure is resilient and deeply submerged under water, it does not hinder ships from passing over it. Therefore, it becomes possible to create a calm region on a liquid surface without hindering a navigation of ships and without creating a danger of wrecking the ships.

In a memory system including a host device and one or more nonvolatile memory devices, the host device reads, from a nonvolatile memory device connected in the system, a boot code used to operate a CPU of the host device before the CPU is activated. The boot code reading process is required to be performed with a simple method. A host device (2) transmits a first symbol including a synchronous code to a nonvolatile memory device (1). The nonvolatile memory device (1) receives the first symbol from the host device (2), and transmits a first symbol that is identical to the received first symbol to the host device (2), and then transmits a boot code to the host device (2). In this manner, the host device (2) reads a boot code from the nonvolatile memory device 1 with a simple method.

A data communication system for starting transmission and reception of target data for processing upon recognition that switching between communication modes is completed. The data communication system includes a master communication device and a slave communication device that continuously perform, at a time of switching from half-duplex communication to full-duplex communication, (i) a handshake using a directional control code indicating the switching and a preamble code indicating completion of the switching and (ii) a handshake using the preamble code and an acknowledge code indicating receipt of the preamble code, whereby each of the devices recognizes that the switching between communication modes by the opposite device is completed and starts transmission and reception of the target data.
摘要:
Without corresponding to different address spaces between an access device (100) and a nonvolatile memory device (200), the access device (100) designates a file ID to manage a data storing state only in a physical address space in the nonvolatile memory device (200). The access device (100) sends the nonvolatile memory device (200) a transfer rate through a transfer rate transmitting unit (121). A filling-up rate calculating unit (251) calculates a filling-up rate of a physical block corresponding to an assurance speed required by the access device (100). A remaining amount corresponding to the transfer rate is sought by using the calculated rate and is transmitted to a remaining amount receiving unit (122) of the access device (100).
摘要:
When inputting moving image data into a personal computer for display or for recording on a recording medium, there often occur cases where processing cannot catch up with the input, resulting in interruption of the processing. Also, when performing conversion from an input digital signal having an arbitrary number of samples to an output digital signal having an arbitrary number of samples, prior art methods entail the possibility that the memory capacity and the amount of computation may become enormous. In view of this, according to the present invention, if the image processing cannot catch up with the input, the data is re-input for processing by utilizing information concerning the recorded position, the recorded time, or the time at which playback is to be performed; this achieves the same effect as processing continuous moving image data without interruption.

It is an object of the invention to time independent common times for a plurality of processing system groups, respectively. It is another object of the invention to take a synchronization in the vicinity of the start of reproduction also when a difference is made over a time taken to prepare for the processing of each processing system. Counting unit (12) manages the common times of a plurality of processing system groups (16) and (17) to time a common time for each of the processing system groups, and time supply unit (13) supplies the common time obtained by the counting of the counting unit (12) to each of processing systems (161), (162), (171) and (172). Moreover, counting control unit (14) controls to start and stop the counting based on notices given from the processing systems (161), (162), (171) and (172) of the processing system groups (16) and (17). The processing system groups (16) and (17) carry out synchronous data transmission processings with each other based on the common time supplied from the counting supply unit (13) in relation to data received from data supply unit (151) and (152). Then, the data transmitted synchronously are reproduced in data reproducing unit (181) and (182).
