Title: Cell transmission method
Inventor: TANAKA YASUO
IPC: H04L12/26
Filed: 1994-03-18
Abstract: PURPOSE:To improve the transmission efficiency of multiplexed/demultiplexed cells by reading cells from only a cell buffer corresponding to a register whose flag is set. CONSTITUTION:When a cell reaches a cell buffer 1 provided to each input link, a cell validity discrimination section 6 checks an address part of the cell header and sets a flag to a register 2 corresponding to the address when the cell is valid. A cell buffer read control section 3 periodically checks the flag of the register 2 and sends a cell enable signal to the cell buffer 1 corresponding to the address of the register 2 whose flag is set. Only the cell in the cell buffer 1 receiving a cell enable signal is read and sent to an output link via a multiplexer section 7. When the cell is read, the flag of the register 2 whose address corresponds to that of the cell buffer 1 is cleared. A defect of extended wait time of a link with a high frequency of use in the method of accessing the cell buffer 1 periodically is eliminated.

Title: Production for magnetic head
Inventor: HANDA TSUNEO
IPC: G11B5/133
Filed: 1984-03-13
Abstract: PURPOSE:To reduce air bubbles to such size that they can be ignored and to improve the durability by adding operations, where a glass is heated at a temperature higher than the melting point and is flowed and the atmospheric gas pressure is raised and a core is cooled in this state, to a glass melt-fixing process. CONSTITUTION:In the figure, the temperature in the melt-fixing process is indicated by a solid line, and the pressure in a furnace is indicated by a dotted line. The pressure in the furnace is raised when the period in which a temperature TW of glass melt-fixing is held is terminated, and this pressure is held until the temperature falls to Tb. It is sufficient if Tb is lower than a strain point (a temperature corresponding to 10<14.5> poise viscocity), and about several-10 atmospheres are enough for this pressure, and the result is not changed even if a pressure higher than them is applied. Thus, not only air bubbles having 10-50mum diameter but also air bubbles 7 having 1-2mum diameter shown in the figure disappear and only about <=0.5 air bubbles having about 5mum maximum diameter appear because the size of generated air bubbles is reduced by application of the pressure and gas in air bubbles is dissolved in the glass.

Title: Nuclear reactor material
Inventor: FUKUSHIMA KIMICHIKA
IPC: C01G55/00
Filed: 1994-03-18
Abstract: PURPOSE:To obtain a nuclear reactor material having an excellent corrosion resistance in a fluid sodium, by providing a stainless steel layer and a single element covering layer to cover the stainless steel layer. CONSTITUTION:A nuclear fuel rod 1 is provided in a fuel box a liquid sodium P is contacted to the outer surface of a cladding pipe 2. In this case, the cladding pipe 2 and an end plug 4 are made of an austenite system stainless steel, and the side contacting to the sodium P is covered by a covering layer 7 of a single element such as Cr and Ni. Since the Cr and the Ni are different from the Cr and the Ni to be the component element of the stainless steel, having no charge, an ionic mutual reaction with the oxygen impurity and a sodium atom having a charge in the sodium P is hardly generated. Consequently, the discharge amount of the Cr and the Ni in the sodium P is very little compared with the Cr and the Ni in the stainless steel. By providing the covering layer 7 which consists of a single element of Cr or Ni hardly having a charge, on the stainless steel surface liable to have a charge, in such a way, the corrosion resistance in the sodium P is improved.
