Title: Automatic focusing device
Inventor: HIGASHIHARA MASAKI
IPC: G03B13/36
Filed: 1987-12-24
Abstract: PURPOSE:To eliminate a wrong prediction, to attain a natural usage feeling and to secure high following property by discriminating whether a current range-finding object is the same as a preceding one and correcting based on the result. CONSTITUTION:To perform predictable control, predictable calculation is decided to be possible or not. If so, a lens driving amount is calculated. For the current predictable calculation, the current, preceding and the last but one defocus amounts DF3, DF1 and DF2, the current and preceding lens driving amounts DL2 and DL1, and the time interval between the preceding time and the last but one are integrated as data. Then, the number of focusing actions is counted and is discriminated whether it >2 or not. When the number is >=three, predictable calculation is performed according to a prescribed expression through the use of said data. As a result, even if a photographer changes an object halfway, wrong prediction never occurs to secure high following property.

Title: Immersion tube for vacuum degassing apparatus
Inventor: KAWAMOTO EIJI
IPC: C21C7/10
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve durability, to reduce the damage to a lower step part and to enable the reducing of a repairing work by arranging grooves in the vertical direction of the axial direction on a cylindrical iron core. SOLUTION: The grooves 5 are arranged in the vertical direction of the axial direction on the side or the outside of the cylindrical iron core 3 arranged in refractory material of an immersion tube for a vacuum degassing apparatus. Extension caused by expansion to the outer direction particularly in the lower part is restrained by arranging the grooves 5 to reduce the damage to the lower part refractory. When the number and the arrangement of the grooves are excessively increased, since the lowering of strength of the iron core is brought about, these are decided in consideration of the thickness, inner diameter, using condition, etc., of the iron core. The size of the grooves are considered in the typical range of 5-10mm width and 5-10mm depth, and the length in the vertical direction is generally about 200mm. Consequently, the effect on preventing deformation is obtained.

Title: Structure of furnace wall of fluidized-bed boiler
Inventor: YOSHIZAWA NOBUYUKI
IPC: F23C10/18
Filed: 1994-12-28
Abstract: PURPOSE: To suppress wear of a water-cooled wall which is due to falling particulates by providing a flow-straightening means for particulates close to the upper end of a refractory material with which the water-cooled wall is lined in part. CONSTITUTION: Coal burns at high temperatures while combustion air fluidizes it together with a bed material comprising such as ash or limestone, throughout a furnace. Particulates of the bed material etc., flying about from the furnace, are returned to the furnace and circulate. Water-cooled wall 2, forming the side wall of the furnace and lined in part with a refractory material 21, keeps the temperature inside the furnace at prescribed points so as to reduce NOX, etc. Each of flow-straightening plates 23 is formed in a rectangle and is fixed by welding or the like to the water- cooled wall 2, specifically at a boundary between the wall part 2b and a water tube 2a, in a manner of being held at right angles to the water-cooled wall 2 and with the lower end in contact with the upper end of the refractory material 21.  The flow- straightening plate 23 suppresses the fall of particulates by flowing down on the periphery of the water tube 2a. Particulates which impinge upon the upper end of the refractory material 21 move away from the periphery of the water tube 2a and guided down into the furnace. Falling particulates that hit the water tube 2a decrease and wear of the water-cooled wall 2 is suppressed.

Abstract: PURPOSE:To prevent lap fillet welding from deviating to the upper plate side by comparing a current integration value at both ends of oscillation with the current integration value at the center of oscillation at the time of oscillating a torch in the direction of width of a groove to perform welding. CONSTITUTION:When the welding current integration value at the center of oscillation becomes higher than that at both ends of oscillation, it can be detected that the lap fillet welding is in an inclined state to run on the upper plate 2 side. However, according to a joint shape, material and welding conditions of materials to be welded, the upper plate side edge is molten and even in the state run on the upper plate 2 side, in certain cases, the welding current integration value at the center of oscillation does not become higher than that at both ends of oscillation. As a result, the welding current integration value at the center of oscillation is offset by (a) and (b) and compared with the welding current integration value at both ends of oscillation and the state run on the upper state 2 side is detected.

Abstract: PURPOSE:To correct the movement of the screen due to hand blur and to obtain a normal pattern by providing,e.g., >=2 acceleration sensors to a photographing device case, applying arithmetic processing to outputs of plural acceleration sensors and giving the result to a memory circuit or an address control circuit controlling a photoelectric conversion means. CONSTITUTION:A difference of outputs of the acceleration sensors 9, 10 in pairs represents a horizontal turning of the photographing device 1 and its absolute value depicts the horizontal movement. Then the output of the acceleration sensors 9, 10 is subject to arithmetic operation by an arithmetic circuit 2 to obtain a horizontal moving vector signal on the screen by the movement. Similarly, the vertical movement vector signal is obtained and given to the address control circuit 3. On the other hand, a photographing element 8 applies photoelectric conversion to a range larger than the desired video range and applies analog-digital conversion and stores the result in a memory circuit 4. The address control circuit 3 uses the horizontal movement vector signal and the vertical movement vector signal to control the readout start address of the memory section to control the output of the memory circuit 4 so that there is no movement of the screen. As a result, the movement of the pattern due to hand blur is corrected.
