Filed: 1990-10-19
Abstract: PURPOSE:To simply form T-shaped wiring without requiring special resist by forming temporary wiring having the same width as the lower part of T-shape, then covering such wiring with a resist layer, thereafter providing a gap in the periphery thereof and then baking the entire part. CONSTITUTION:A temporary gate 8a is formed in such a width as the lower part of a T-shaped gate electrode on a substrate 1. With the exposure and development process, a small gap 22 is prepared in the periphery of the gate 8a and a hole is provided on a resist 21. The substrate 1 is baked so that the resist 21 covers the substrate 1, leaving the width of gate 8a uncovered. Therefore, exposure to form a hole on the resist 21 can be made rather roughly. Moreover, since the gate 8a is provided, the gate is never narrowered excessively and is disconnected. The gate 8a is eliminated, a metal layer 22 is evaporated and an upper resist 23 is coated on the entire part. With the exposure and development process, the resist 23 is removed, leaving an upper part 24 of the T-shaped gate electrode and ions such as Ar<+> are implanated. Thereby, the resists 24 and 21 on the electrode 19 can be removed with an organic solvent which removes the layer 22 other than those covered with the upper part 24.

Inventor: SAIJO MASARU
IPC: F23N1/08
Filed: 1985-12-17
Abstract: PURPOSE:To provide a control device which brings stably air amount corresponding to gas amount into a burning range even if burning amount is varied by controlling a fan after operational burning amount is calculated on the detected values from a detector for feed water temp., a detector for hot water supply temp., and a water meter. CONSTITUTION:Water amount is detected by a water meter 13 and when water amount is over predetermined amount, indications are put out to a proportional valve 7 and a fan 9 from a controller 17 and a gas burner 8 starts to burn. Water in a water path 15 changes hot water and its temp. approaches a predetermined set temp. When a detector 16 for hot water supply temp. begins to show a value greater than designated, the controller 17 starts to throttle the valve 7 to keep hot water temp. at the designated value. At that time, the fan 9 reduces air amount at the rate corresponding to a value obtained by dividing supplied hot water calorie calculated from feed temp., hot water temp., and water amount by heat exchanging efficiency, that is, operational burning amount to secure burning stably.

Abstract: PURPOSE:To eliminate the defective picture elements and to decide an accurate driving course of an unmanned carrier by controlling the steering mechanism based on the centroid position only when the centroid position of a line having the width picked up into an image is set on a driving line. CONSTITUTION:A CCD camera 3 is set on a driving unmanned carrier 1 and picks up a driving line 6 indicating the driving course of the carrier 1. An A/D converting circuit 16 codes the picture element signals of the image picked up by the camera 3 for production of the picture element data. These coded picture elements are stored in a program memory 12 in the form of the picture element data. For this data a CPU 11 calculates the centroid position of a line having the width and picked up in the image. Then it is decided by a scan train whether the centroid position is set on the line 6 or not. A steering mechanism 19 is controlled 20 based on the centroid position only when this centroid position is set on the line 6.

Title: Soft water manufacturing device
Inventor: SAKAMOTO SHUICHI
IPC: C02F1/44
Filed: 1989-10-31
Abstract: PURPOSE:To manufacture soft water continuously by dialyzing untreated water with a Donnan membrane using a blow water from a boiler as a recycling agent. CONSTITUTION:Untreated water containing hard components such as Ca<2+> or Mg<2+> is supplied to a treated liquid chamber 3 from an untreated water tube 11, and blow water containing a high percentage of alkali metal ion is supplied from a boiler 2 to a recycling agent chamber 4 through a blow water tube 13 for water softening. In this case, a cation exchange membrane 5 is of an alkali metal ion (Na) type because of the high alkali ion concentration of blow water. However, the hard component of untreated water is selected more easily than the soft component, so that an ion exchange takes place. The cation exchange membrane 5 becomes an alkali metal ion-type membrane after it exchanges the hard component and is recycled with a blow water. Subsequently, the untreated water is dialyzed with the help of a Donnan membrane using a concentration gradient as a driving force. After this, the hard component of the untreated water is dialyzed into the recycling agent chamber 4 side and the alkali metal ion of the blow water is dialyzed into the treated liquid chamber 3 side respectively. Thus the untreated water is softened.
