Title: Evaporation type petroleum combustion device
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23D11/02
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a combustion device which easily conducts cleaning of a vaporizer. SOLUTION: When a cleaning switch 13 is in operation, even if a petroleum sensing device 11 senses a decrease in quantity of petroleum in a petroleum tank 7, a display 14 for displaying oil shortage is not actuated and operation of an electric heater 1 and a pump 8 is continued and thereafter petroleum cannot be pumped up from a suction pipe 10 of the pump 8 and delivery of air is started and hence flames cannot be formed in a burner 5 and flame is not sensed by a flame sensing element 12, whereupon, while the action of the pump 8 is continued, temperature of a vaporizer 3 is controlled to a temperature (about 500 deg.C) suitable for cleaning, which is higher than that of normal burning, and air is sent into the vaporizer 3 to oxidize and burn tar component deposited in the vaporizer 3, without being vaporized,  in order that a cleaning operation is performed for a predetermined period of time. Thus, cleaning can be optionally carried out to always maintain a desired performance of the combustion device.

IPC: H04N5/232
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To easily focus a camera on an object by superimposing a preliminarily stored image pickup composition and a focus position decided about the composition on a surrounding subject image to display them and performing focus control of the image at the focus position. SOLUTION: A user operates a cursor shifting key and designates a cursor position to bring a prescribed position in a displayed focus position into focus. A controlling part checks a state signal from an operating part, and when the cursor shifting key is operated, the controlling part further examines the state signal from the operating part. Then, it decides whether the cursor shifting key is operated to the left or to the right. When the cursor shifting key is operated to the right, the first right focus position 87 is displayed, and when it is operated to the left, the first left focus position 84 is displayed. Thus, a user can visually decide the propriety of a focus position and can perform a cursor operation again when it is not a desired position.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To measure a bottom diameter in a wide range with high precision by measuring the bottom diameter of an object to be measured on the basis of computing based on detection results from a differential transformer and a high precision scale. SOLUTION: A precise stopping position of a measurement unit 6 is electrically stored in the form of a reading value S1 of a high precision scale 7. A change quantity of a bottom diameter 2 is measured by means of a differential transformer 4 via a measurement element 3, and its minimum value Ti is electrically stored. When a measurement value of the differential transformer 4 becomes a total of the minimum value Ti and a constant quantity, a signal is outputted to a motor 9 and the measurement unit 6 is released. The release of the measurement unit 6 is to prevent interference between the measurement element 3 and an object 1 to be measured, which may destroy a measurement device. The same operation is repeated N times which is the number of teeth.  As a result, a bottom diameter D can be found according to an expression: D=D0-ΣSi/N+ΣTi/N, if a reference diameter is represented by D0 when reference values S, T for the measurement device are zero.
