Title: Safety device for burning implement
Inventor: SAKAMOTO AKIO
IPC: F24C3/12
Filed: 1995-01-26
Abstract: PURPOSE: To form a low-cost safety device having high reliability by connecting a thermoelectric circuit having a thermocouple and a solenoid valve to the drain and the source of a field effect transistor, and connecting a power source and a conduction control circuit having a bimetal switch to the gate and the source of the transistor. CONSTITUTION: Since a conduction control circuit 1 is normally conducted by a power source (dry cell) 2 and a voltage is applied to the gate of a field effect transistor 5, the resistance between the drain and the source is reduced, and the thermocouple 8 of a thermoelectric circuit 7 can supply a suction current to a solenoid valve 9. When a bimetal switch 3 raised at its temperature reaches a set temperature, it is turned OFF to interrupt the conduction of the circuit 1, and hence a gate voltage is not applied to the transistor 5, the resistance between the drain and the source is raised, the suction current to the valve 9 at the thermocouple 8 is reduced, and the valve 9 is closed. Thus, a low-cost safety device having high reliability can be simply formed.

Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To make smooth the surface of metal film while reducing residual halogen in the film by forming a metal on a substrate to be processed using a mixture gas containing a metal halide and hydrogen while terminating the surface of substrate to be processed with a hydrogen active species. SOLUTION: An interlayer insulation film 2 is formed on a semiconductor substrate 1 and a contact hole 3 is made therein. Native oxide on an impurity diffusion layer exposed to the bottom of contact hole is then removed by diluted hydrofluoric acid and the bottom of contact hole is cleaned by plasma processing using hydrogen/argon gas. Subsequently, a Ti layer is subjected to plasma CVD using a mixture gas of TiCl4 /H2 /Ar where the flow rate of hydrogen is high. Consequently, the surface of substrate to be processed is terminated with a hydrogen active species 8. A precursor in the form of TiClx (x is a natural number smaller than 4) excited in the plasma eventually arrives at the surface of substrate and a Ti metal film 4 is grown uniformly even on the bottom of contact hole 3.
