Title: Manufacture of semiconductor memory device
Inventor: YAMAZAKI NOBUO
IPC: H01L29/792
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain proper electrical characteristics by forming an oxide barrier layer after forming a lower electrode and then heat treating it at a high temperature in an atmosphere containing oxygen to prevent volume expansion, peeling or the like. SOLUTION: A barrier metal layer 8 is formed on a polysilicon plug 7 in a contact hole. A lower electrode 9 is formed on the barrier metal layer 8. After the barrier metal layer 8 and the lower electrode 9 are subject to well- known photolithography and dry etching, an oxide barrier layer 12 is formed. Then process damage recovering annealing is performed in an atmosphere containing oxygen. In this way, since the oxide barrier layer 12 is formed after treating the barrier metal layer 8 and the lower electrode 9 and high- temperature heat treating the oxide barrier layer 12 in an atmosphere containing oxygen, the lower electrode 9 and the barrier metal layer 8 are never oxidized. Accordingly, damages suffered by a ferroelectric film 10 during semiconductor process can be sufficiently recovered and proper electrical characteristics can be obtained.

Title: Air conditioner
Inventor: OKAMOTO TAKAHIRO
IPC: F25B13/00
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent the reliability of a compressor from lowering due to mixing of liquid refrigerant into gas refrigerant being returned from a gas-liquid separator inserted into a liquid tube back to the compressor through a bypass tube for gas injection. SOLUTION: When the temperature difference between the outlet temperature of a compressor and the condensation temperature of refrigerant drops below a reference level, an on/off valve 14 of bypass piping 13 is closed to stop gas injection. Outlet temperature drops when liquid refrigerant is mixed, and temperature difference between the outlet temperature and the condensation temperature is decreased. When it is compared with a reference temperature difference, the temperature difference can be detected while being distinguished from outlet temperature drop corresponding to variation of operating conditions. Reliability of compressor can be enhanced by stopping gas injection automatically when the liquid refrigerant is mixed based on the detected temperature difference.

Title: Production of quartz glass-base optical transmission line
Inventor: KUZUSHITA HIROKAZU
IPC: G02B6/44
Filed: 1986-12-24
Abstract: PURPOSE:To prevent the deterioration of the surface of an optical transmission line and the reduction of the mechanical strength by drawing a base material, immediately coating the resulting quartz glass-base optical transmission line with polyimide varnish having <=1wt.% water content and baking the varnish. CONSTITUTION:A base material is drawn as usual and the surface of the resulting optical transmission body is coated with varnish prepd. by dissolving a polyimide precursor in an org. solvent such as N-2-methylpyrrolidone, acetone or xylene. The varnish is then baked to form a primary coating layer. When the water content in the varnish is >1wt.%, the water in the varnish attacks the surface of the optical transmission body, promotes microcracking and reduces the mechanical strength of the body. In case of >1wt.% water content, dehydration or drying is carried out by a proper method before coating. The reduction of the mechanical strength of the optical transmission line due to the deterioration of the surface of the path by the water in the varnish can be prevented.
