Patent JP-H11214499-A (JP)
Title: Fabrication of semiconductor device
Inventor: HOTTA KATSUYUKI
IPC: H01L21/3105
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To enhance planarity on the surface to be processed by filling the trench opening with an insulating film, preplanarizing the surface by removing the insulating film laminated excessively on a semiconductor substrate through dry etching, and then polishing the surface by a CMP method thereby reducing the quantity to be polished by the CMP method. SOLUTION: A trench opening 2 is filled completely by depositing HDP-CVD oxide 3a through HDP-CVD. The oxide 3a is then subjected to dry etching using a resist pattern 8 formed on a trench isolation 3 as an etching mask thus removing excess oxide 3a and leaving the oxide 3a only at a part for forming the trench isolation 3. Subsequently, the pattern 8 is removed and polishing is performed by CMP using a silicon nitride as a stopper to remove polysilicon composing mask patterns 7a, 7b, 7c. Polishing is performed simultaneously for the oxide 3a in order to planarize the surface to be processed thus enhancing surface planarity.

Title: Combustion safety device for burner
Inventor: MAEDA JIYUNICHI
IPC: F23N5/24
Filed: 1984-01-31
Abstract: PURPOSE:To enable quick stop of combustion when oxygen concentration is decreased, by a method wherein poor combustion of a burner is made easy to occur through intermittent decrease in the excess rate of a primary air. CONSTITUTION:Switching of a blower 3 to an intermittent low rotation is controlled by an interval timer circuit 28, a time required for counting made the specified number of times is reduced to, for example, 1.5min, and the output of an output terminal 29a is switched to a high level again 1.5min later. Switching of the blower 3 from high rotation to low rotation results in a decrease in the excess rate of a primary air of an auxiliary burner 6 to, for example, 0.7. If oxygen concentration is reduced to 16-18%, poor combustion occurs to the auxiliary burner 6 to detect such poor combustion by means of a second thermocouple 18, and with an electromagnetic safety valve 7 closed, combustion is brought to a stop. As noted above, by means of signals from sensors 17 and 18 which detect poor combustion during intermittent combustion by which a decrease in the excess rate of the primary air is caused, combustion is brought to a stop, resulting in ensurance of safety.

Filed: 1993-02-02
Abstract: PURPOSE:To obytain a catalyst with enhanced exhaust gas purification performance and improved heat resistance by increasing and making uniform the dispersedness of an active species carried by a metal-containing silicate as a bearing base material. CONSTITUTION:When allowing a precious metal active species containing Ir to be carried by a metal-containing silicate, an organic solvent having an approximate boiling point to that of water which is the solvent of salts of the precious metal other than Ir is used as a solvent for salts of Ir. Consequently, Ir and a precious metal other than Ir as active species are allowed to deposit on the metal-containing silicate almost simultaneously. Thus it is possible to obtain the uniform and dispersedness rich bearing state of the active species.
