Abstract: PURPOSE:To improve the resistance to nitric acid at a weld zone by a protective layer to improve the resistance to nitric acid after welding by forming the above-mentioned protective layer before welding on a groove of stainless steels containing Mo and then, performing welding by using a welding rod of stainless steel containing Mo. CONSTITUTION:Material to constitute the vessel, etc., is made of the stainless steel containing Mo and welding is performed on the welding groove of this material by using the welding rod made of the stainless steel of the same quality as this material. Before this welding, the protective layer to improve the resistance to nitric acid is provided. As this protective layer, Y308L, etc., not containing Mo as a build-up layer 14 and a lip layer 15 is formed by welding as the welding rod.

Title: Driving method of optical modulating element
Inventor: ISHIWATARI KAZUYA
IPC: G02F1/163
Filed: 1984-01-24
Abstract: PURPOSE:To prolong the life of an optical modulating element by applying a voltage so that the pulse width in an off signal application period is shorter than that in an on signal application period and the polarity is opposite. CONSTITUTION:An electrochromic element is formed by laminating the 1st electrode 2 of a transparent conductor film, an oxidation coloring electrochromic layer 3, an insulating layer 4 of a dielectric film, and the 2nd electrode 5 of a conductor film successively on a transparent substrate 1. Electrochemical reaction is caused by applying a voltage between the electrodes 2 and 5 to perform coloration and discoloration. The voltage applied between the electrodes 2 and 5 in the on signal application period has larger width than the voltage in the off signal application period and is opposite in polarity. Thus, the stable operation life of the electrochromic element is prolonged.

Inventor: TAKAGI HIROSHI
IPC: H01L29/78
Filed: 1988-01-20
Abstract: PURPOSE:To prevent a hot electron phenomenon from being produced for assuring high reliability and high speed switching by leaving a CVD oxide film only on the side corresponding to a drain in the vicinity of a polysilicon gate. CONSTITUTION:A MOS type field effect transistor includes a gate oxide film 3 and a polysilicon gate 4 selectivity formed in succession on a first conductivity type silicon semiconductor substrate 1, and a second conductivity type high concentration diffusion layer 9 to become a drain region and a source region. Thereupon, a low concentration diffusion layer 6D is formed of a remaining CVD oxide film on the side corresponding to a drain in the vicinity of the polysilicon gate 4. Hereby, on the drain region side, a hot electron phenomenon directly associated with the drain region can be prevented, while on the source region side no CVD oxide film is formed in the vicinity of the polysilicon gate 4, thus preventing a current gain of the device from being reduced. As a result, the hot electron phenomenon can be prevented, thereby enabling high speed switching to be performed.
