An OPU frame generating device includes a frequency setting unit that sets a frequency corresponding to a bit rate of data which can be stored in a payload area, a parameter calculating unit that calculates a parameter Cm indicating an integer part of the amount of data included in the payload area using the set frequency, a data inserting unit that outputs a timing signal determined by the parameter Cm and inserts data at a position determined by the parameter Cm in the payload area, a data generating unit that generates data in synchronization with the timing signal, and a frame generating unit that generates an OPU frame having the payload area into which the data is inserted.

An M-sequence generator includes EXCLUSIVE-OR gates feeding back pieces of bit data from m number of series registers to the registers in response to a clock. A period of a cyclic group {(α1k), (α2k), (α3k), . . . } falls within a maximum period (2m−1), the group being produced as an element (αk) obtained by raising a root α of a polynomial to a specified power value k (k≧2), which have the terms in polynomials of a Galois field GF(2m). In a multiplying unit including the gates, pieces of bit data is fed into one end of the multiplying unit in response to the clock while the element (αk) is fed into the other end. The multiplying unit performs Galois field multiplication between each piece of bit data and the element (αk), the gate supplies the multiplication result as feedback bit data to the respective registers.

An error addition apparatus receives a data signal D having a frame format having a specific signal inserted into its front, adds errors to the data signal D, and outputs a resulting signal. The apparatus has an error addition regulation unit for receiving a frame synchronization signal F, indicative of a timing at which the front of the frame of the data signal has been inputted, and regulating the errors such that the errors are added to positions other than a region of the specific signal. Accordingly, errors are not added to a specific signal.

An endless transmission belt is formed of a plurality of symmetrical V blocks. Each V block comprises upper and lower portions disposed approximately parallel to each other, and two pillar portions connecting the upper and lower portions. The block includes side openings on both sides, and a center opening between the pillar portions. The upper and lower portions have wavy configurations, so that the upper and lower portions have flexibility against the force applied from sheaves to the V block.

摘要:
A Group III metal element is heated so as to melt, a gas NH3 containing nitrogen atoms is injected into a melt 3 of the Group III metal element at a temperature lower than the melting point of a nitride to be obtained, thereby producing a nitride microcrystal of the Group III element having high wettability with the melt 3 in the melt 3 of the Group III metal element. A mixture of the Group III nitride microcrystal obtained as mentioned above and the Group III metal element solution is used as a starting material of a liquid phase growth or Group III nitride powders obtained by removing the Group III metal material from the mixture are used as a starting material of a vapor phase growth. Further, a seed crystal or a substrate crystal is immersed in a melt of a Group III element such as gallium, bubbles of a gas containing nitrogen such as ammonia are intermittently come into contact with the surface of the crystal, and the Group III element and the gas containing nitrogen are allowed to react with each other on the surface of the seed crystal or the substrate crystal, thereby allowing the nitride crystal of the Group III element to be grown on the surface of the seed crystal or substrate crystal.
