Abstract: PURPOSE:To enable a film to be grown at a lower temperature and enhanced in growth rate by providing an active Si layer subjected to solid state growth of an a-Si formed through a CVD method by the use of polysilane doped with Cl2. CONSTITUTION:An SiO2 film 2 is formed on a substrate 1, and an a-Si layer 3 is formed thereon through a CVD method by the use of polysilane SinH2(n+1) (n is an integer of 1 or above) where Cl2 is added. A gate oxide film 4 is formed thereon. The a-Si layer 3 is made to grow in solid phase into an active Si layer. A silicon layer 5 to serve as a gate electrode is formed on the gate oxide film 4 to constitute a TFT. In this case, the gate oxide film 4 is formed on the a-Si layer 3 which is formed through a CVD method by the use of polysilane doped with Cl2, and then the a-Si layer 3 is made to grow in solid phase and into an active Si layer. By this setup, the a-Si layer 3 can be formed not only at a low temperature but also at a higher growth rate, so that a TFT excellent in characteristics can be obtained high in productivity.

Title: Information reproducing device
Inventor: TANIWA SHIGEYUKI
IPC: G06F3/06
Filed: 1990-11-27
Abstract: PURPOSE:To reduce the burden of a CPU and to improve the overall throughput by transferring the control information directly to a working RAM without passing through a buffer RAM when the data are reproduced. CONSTITUTION:A CPU 46 issues an instruction to a disk controller ODC 4A to read the data. The ODC 4A detects a prescribed sector to start the read of a data part and transfers the data on an alternate control information sector to the FIFO memories 17 and 18 in the ODC 4A. The memory 17 transfers the received data to the working RAM 48 through a CPU bus interface 19, and the memory 18 transfers the received data to a buffer RAM 44 through a buffer bus interface 1A. Thus the CPU 46 is not required to transfer again the control information sent once to the RAM 44 to the RAM 48. Thus, the burden of the CPU 46 due to the transfer of data is reduced and the overall throughput is improved.

Inventor: MAKUTA YUKIO
IPC: B23K11/14
Filed: 1993-12-22
Abstract: PURPOSE:To prevent a splashed material from occurring and to obtain sufficient welding strength. CONSTITUTION:A welding current (i) flows on a first contact part between a projection 2 and a material 4 to be welded at the initial stage of welding, however. it flows on a second contact part 8 between a bank projection 3 and the material 4 to be welded afterwards. therefore. the current (i) is diverted to two currents, the current (i) 1 that flows on the first contact part and the current (i) 2 that flows on the second contact part 8. In this way, since the welding current per unit area that flows on the first contact part is reduced, it is possible to set the current density of the current on the first contact part at the one less than limitation where the splashed material occurs in spite of the formation of a large nugget on the first contact part, which enables a material occurring as the splashed material to be remarkably suppressed.
