摘要:
A process for producing a low yield ratio, high strength two-phase steel sheet comprising hot rolling a steel composition containing 0.03 to 0.13% C, 0.8 to 1.7% Mn, not more than 0.1% Al, not more than 2.0% Si and not more than 0.5% Cr with a finishing temperature ranging from 750.degree. C. to 890.degree. C., rapidly cooling the strip to a temperature not higher than 230.degree. C., and coiling the strip at a temperature not higher than 230.degree. C. with the temperature variation during the period between the start and end of the coiling being no more than 100 degrees C. The Si content is limited to 1% or less for applications where paintability is of primary importance, and is limited to a range of from 1 to 2% for applications where the ductility is of primary importance. The process effects improvements in the artificial ageing property after working which improvement is uniform throughout the whole length of a coiled strip. The product obtained by the process is also described.
摘要:
A method for producing a low alloy hot rolled steel strip or sheet comprising hot rolling a steel slab at a finishing temperature not higher than the Ar.sub.3 transformation temperature plus 60.degree. C. and cooling and coiling the hot rolled strip at a temperature not higher than 500.degree. C. The steel slab contains not more than 0.20% carbon, 0.50 to 2.50% manganese and 0.05 to 1.0% chromium and optionally contains not more than 1.0% silicon, the balance being iron and unavoidable impurities. The resultant strip or sheet has a high tensile strength of not less than 40 kg/mm.sup.2, a low yeild ratio of not more than 70% and an excellent total elongation of not less than 25%.
摘要:
A method for producing two-phase steel sheets having a material quality equal to or better than the conventional two-phase steel sheets by an addition of a very small amount of B so as to considerably reduce the contents of steel constituents, such as Mn and Si, thus eliminating the problems concerning the production cost, descaling in the processing and material quality in the ultimate applications.

A method for closing a hole with a coating is provided. The method comprises attaching the subject body to an electric spark machine as a workpiece; bringing an electrode of a powder including an electrically conductive substance close to the subject body so as to lap the electrode over the hole; applying a voltage between the electrode and the subject body so as to generate electric discharge repetitiously to cause a coating closing the hole to grow from a periphery of the hole; and machining an edge of the hole before applying the voltage, or the coating along the edge of the hole during repetition of applying the voltage, to give a bevel.

摘要:
A data transmission apparatus connecting to a network consisted of a plurality of data transmission apparatuses comprises a disconnecting device that disconnects a connection established between a transmission plug of a transmitting node and a reception plug of a receiving node, both nodes being connected to the network, an optimization requesting device that requests optimization of transmitting sequences to the transmitting node, a receiver that receives information about a transmission plug newly assigned to the transmitting sequence used by the transmitting nodes of which connection has been disconnected by the disconnecting device, the information being received as an answer for the optimization request from the transmitting node, and a connecting device that establishes a new connection between the newly assigned transmission plug and the reception plug of the receiving node of which connection has been disconnected by the disconnecting device.
摘要:
A recording apparatus, a recording method, a salvage apparatus, a salvage method, and a program for reading data from a recording medium that has failed to normally end a recording process. Each of salvage markers contains a recognition pattern for recognizing a salvage marker, and identification information for identifying files to which audio data “Audio”, and video data “Video” belong. If the recording process fails to end in a normal state, the salvage markers are detected from the recognition pattern contained in the salvage markers, and the file having the audio data and the video data belonging thereto is identified by the file identification information. The present invention is applicable to a video processing apparatus.
摘要:
For adjusting a positional relationship between a specimen and a probe to measure an electric characteristic of the specimen through a contact therebetween, a base table holding a specimen table holding the specimen and a probe holder holding the probe is positioned at a first position to measure the positional relationship between the probe and the specimen at the first position, and subsequently positioned at a second position to measure the positional relationship therebetween at the second position so that the probe and the specimen are contact each other at the second position, the specimen table and the probe holder are movable with respect to each other on the base table at each of the first and second positions to adjust the positional relationship between the probe and the specimen, and a measuring accuracy at the second position is superior to a measuring accuracy at the first position.
摘要:
A method and apparatus for generating and editing audio and/or video data using thumbnail representations of the data. Thumbnail representations are generated in accordance with clips randomly recorded on a disc, or other storage medium, and edit points are designated for the clips. When thumbnail representations are displayed, the disc is rotated at constant angular velocity (CAV). Video data of the thumbnail representations are read from the disc. When a desired thumbnail representation is selected and designated, the disc drive system is switched from CAV drive mode to constant linear velocity (CLV) drive mode. Video are reproduced from the position of the selected thumbnail representations. Since the thumbnail representations are read in the CAV drive mode that is suitable for randomly accessing the disc, the thumbnail representations can be displayed at high speed.
