Title: Method and apparatus for making pcb harmless
Inventor: TAKESHITA SHIGEO
IPC: C07C17/00
Filed: 1982-07-30
Abstract: PURPOSE:To carry out the detoxification of PCB surely and easily at reduced cost, by heating a specific granular catalyst acting as an oxidative decomposition catalyst forming a metal oxide, at a temperature above the dissociation temperature of PCB, thereby accelerating the evaporation, thermal decomposition and combustion of PCB. CONSTITUTION:A porous natural mineral containing various kinds of metal elements capable of forming metal oxides with heat and acting as an oxidative decomposition catalyst, or a natural or artificial mineral such as pumice stone impregnated with a solution of a salt which forms a metallic oxide with heat, is used as granular catalyst 6. The furnace 1 containing the layer of the granular catalyst 6 is preheated at a temperature above the decomposition point of PCB. PCB is passed upward through the gap between the catalyst granules 6 to effect successive evaporation, thermal decomposition and combustion at a temperature above the decomposition point of PCB. The above reactions are accelerated by the catalytic action of the granular catalyst 6. The generated chlorine gas is made completely harmless by the adsorption and neutralization in the chlorine gas-treatment system 13 connected to the furnace 1 through the line 12.

IPC: C23C16/52
Filed: 1988-05-31
Abstract: PURPOSE:To facilitate easy device designing so as to enable thin-film characteristics of a large thin film to be obtained even if the film thickness is small by applying a power which is larger than the power while being stable for allowing the target thin-film characteristics to be obtained to an electrode at the time of starting to produce film, and then by reducing the applied power to that while being stable after a specified time passes. CONSTITUTION:At the time of introducing reaction gas into a vacuum container and producing an amorphous semiconductor thin film by plasma chemical deposition method, in terms of a thin film produced by setting power applied to the electrode to a value Gs for obtaining target film characteristics, the relationship between the film thickness and the thin-film characteristics is examined previously to obtain a critical film thickness where no thin-film characteristics change according to the size of the film thickness and at the same time to obtain a time T0 from initiation of film production until the film thickness reaches the above critical film thickness. And then, the same gas as the reaction gas used for producing film is introduced into a vacuum container and a power which is larger than the above power Gs is applied to the electrode to initiate production of film and the applied power is reduced to reach the above power Gs after the above time T0 passes, or near it.

Title: Automatic drain control device
Inventor: HIROSE MOTOAKI
IPC: F24H1/20
Filed: 1990-05-23
Abstract: PURPOSE:To prevent hands or fingers from touching hot water to be scalded by a method wherein when a temperature of hot water stored in a hot water storing tank is higher than a predetermined temperature during a water discharging time, water feeding and water discharging are carried out concurrently. CONSTITUTION:When a time of automatic water discharging function set in advance in a schedule table 14 comes, a sensing signal from a temperature sensor 7 is inputted through an input circuit 8 to an operation control function 15. In case that a hot water temperature from a temperature sensor 7 is high, the operation control function 15 sends a signal for opening both valves 10 and 11 to an output circuit 12 and in turn in case that it is low, the operation control function 15 sends a signal for opening only the valve 10 to the output circuit 12. With such an arrangement, hot water in the hot water storing tank to be discharged through a water drain pipe 9 becomes a lower temperature one which does not show any dangerous scalding. A mixing amount of the water fed into the hot water storing tank 1 and the discharged hot water is increased by arranging a position of an opening 9a of a drain pipe 9 near a water feeding pipe 6. Since the opening 9a is projected by a predetermined height from a bottom part within the hot water storing tank 1, the settlements deposited near an electrical heater 5 do not flow into the opening 9a by a presence of a partition plate 19.
