Title: Cone for burner
Inventor: WATANABE TADASHI
IPC: F23D11/36
Filed: 1990-03-05
Abstract: PURPOSE:To reduce the manufacturing cost and enable stable use for a long period of time by providing a plurality of slits for relaxing thermal stress at the end section of a cone for burner of approximately cylindrical shape made of ceramic. CONSTITUTION:Fuel oil sprayed out of a burner nozzle 9 is mixed with combustion air from a wind box 3 and ignited to form a stable flame in a cone 8 for burner. Since the cone 8 is made of ceramic having high thermal resistance and corrosion resistance, the cone 8 is not affected by corrosive substances contained in the fuel. Since slits 11 are formed on the end section 10 which directly contacts the flame and hence the generation of thermal stress can be reduced, cracks are prevented from occurring in said section. Further, the cone made of ceramic can by manufactured by simply forming a cone and burning it, resulting thereby at a reduced manufacturing cost.

Title: Lens driving device and camera
Inventor: MASUDA HIDETOSHI
IPC: G02B7/08
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To surely perform accurate lens driving amount confirming operation and to prevent a lens position detecting mechanism from getting complicated and large-sized by allowing a decision means to perform deciding operation only in one driving direction in the case of restoring a focusing lens to an initial position. SOLUTION: By reversely rotating a motor for focusing driving, the focusing lens is driven and reversely rotated to a standby position O and a standby position O' being a position after the lens passes through a reference position C. Therefore, by driving and reversely rotating the lens by a difference between the position O' previously known and a focusing target position S, the lens reaches the position O'. Continuously, the lens is driven and normally rotated toward the position C. When a reference position signal C is confirmed, the number of driving steps and the position S at that time are compared. If they match with each other, it is decided that the lens is normally driven, so that the lens is kept being driven and normally rotated further and it is driven to the position O, then driving is finished.  Thus, the accurate lens driving amount confirming operation is surely performed.

Abstract: PURPOSE:To obtain a titled device capable of obtaining immediately and accurately the outer diameter of each coil during rolling by a simplified apparatus, by using specific equations for calculating said diameters based on the rotational speeds of unwinding and winding reels, the sheet thicknesses at the inlet and outlet sides of a mill, and coil diameters at the initial stage of unwinding or the diameters at the initial stage of calculation. CONSTITUTION:Speed signals outputted from the pulse generators PLG(r1), PLG(r2) of reels L1, L2 are transmitted to registers R11, R12 through counters C1, C2 and are stored as rotational speeds omega1, omega2. The sheet thicknesses h1, h2 at the inlet and outlet sides of a mill outputted from digital setters DSW1, DSW2 are inputted into multiplying circuits MUL1, MUL2, and are multiplied to obtain products h1omega1, h2omega2. When the coil diameters D10 are known, these values are inputted into the equations I , II from arithmetic circuits CAL1, CAL2 to obtain coil diameters D1, D2 at the optional time. In case of calculating the initial coil diameter D10 based on the initial conditions and the diameter of a mandrel, the calculation is performed by using the circuits CAL1, CAL2 and the equation III. Thus, accurate and reliable coil diameters are obtained, because the need for pulse generators is eliminated to simplify the device, and forward and backward slips are calculated one by one.
