    摘要： An electronic data management system capable of preventing confusion due to transfer of electronic data, even if electronic data attached with original attribute is transferred is provided. This system includes a transfer source server and a transfer destination server connected via a network. The transfer source server retains electronic data having attribute information attached indicating that the electronic data is the original. The transfer source server duplicates the electronic data to create new electronic data and stores the same in conjunction with information indicating that the new electronic data is a duplicate and information identifying the transfer destination server to which the original has been transferred.

    摘要： According to this invention, level shift diodes and are connected between input nodes and output nodes through source follower MESFETs, and the output nodes are connected to a power supply through current source MESFETs and current supply resistors, thereby forming first and second level shift circuit units. A DC bias is applied to the gates of the current source MESFETs through resistors. At the same time, signals having phases opposite to input signals of the current source MESFETs are supplied to the current source MESFETs through capacitors, respectively. A current supply circuit has a gain in a high-frequency range.

    摘要： There is disclosed a digital integrated circuit device which has high-speed transistors of a selected type. A timing controller is incorporated in this device and performs timing control for an internal digital circuit. The timing controller includes a series-circuit of two flip-flop circuits serving as a frequency-dividing circuit for frequency-dividing a reference clock signal and generating an internal timing signal, and a switch circuit connected to a signal feedback line of these flip-flop circuits. In a normal mode, the switch circuit supplies the internal timing signal output from the flip-flop circuits to the digital integrated circuit. At a desired timing, the switch circuit performs a switching operation in response to a control signal, electrically disconnects the signal feedback line of the flip-flop circuits, and alternatively supplies an external timing signal externally supplied thereto to the digital integrated circuit.

    摘要： The invention provides a novel pitch material useful as a base material of carbon fibers having excellent mechanical properties and characterized by a unique combination of several property parameters including the content of the optically anisotropic phase of at least 80%, a content of the pyridine-insoluble matter in the range from 30 to 70% by weight, a number average molecular weight in the range from 1000 to 1400 and a softening point in the range from 330.degree. to 380.degree. C. Such a pitch material is obtained from a starting pitch of a petroleum-based residual oil freed from light oily matter through a two-step heat treatment, of which the first step is performed at 400.degree. to 460.degree. C. under a pressure of 5 to 50 mmHg and the second step is performed at 450.degree. to 550.degree. C. for 0.2 to 30 minutes under a pressure of 0.1 to 5 mmHg. The advantages obtained by use of a film evaporator in the above mentioned heat treatment are described. The time taken for the infusibilization treatment of the pitch filaments is greatly decreased when the filaments were prepared from the inventive pitch material by spinning in comparison with conventional pitches and the spinning temperature can also be relatively low.
