Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a kettle and a food boiling/cooling pot which enables heating of water and boiling and cooking of food about 20-30% more quickly than the cases of using the conventional kettles and food boiling/cooking pots each with a flat bottom by expanding the surface area of the bottom of the apparatus larger than that of the flat bottomed types having the same diameter to allow receiving of the radiation heat of flame of a gas cooking stove at a higher efficiency. SOLUTION: The shape of the cross-section of the bottom of the apparatus is made continuously rectangular or trapezoidal or continuously corrugated in a figure of S each with deep returns. The parts orthogonal to the cross-section are formed into a broad linear deep groove 1 or a gently curved deep groove 2 as viewed from the internal side and the external bottom part of the apparatus to allow receiving of the radiation heat of flame of a gas cooking stove at a higher efficiency. The inside of the apparatus is provided with a broad linear deep groove or a gently curved deep groove from a hygienic point of view with its width exceeding about 20mm and its depth below 40mm, the size which allows human fingers to be inserted to facilitate cleaning by human fingers.  This makes the surface area of the bottom as large as possible due to the shape of the cross-section of the apparatus thus obtained s compared with that of the conventional flat-bottomed apparatus having the same diameter.

Title: Motor control circuit using solar cell
Inventor: MORITA MINORU
IPC: H02P29/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To start a motor securely even if the electromotive force of a solar cell fluctuates. SOLUTION: When a motor is in a resting state, the electromotive force of a solar cell is judged in a state that a dummy load R3 is connected. When the electromotive force reaches a motor operation point, the dummy load is cut off and a motor power supply is turned off. The electromotive force is judged by a comparator 3. Hysteresis characteristics are given to the comparator to suppress the unnecessary fluctuation of the comparator output. When the solar cell electromotive force is not sufficient, the level of the output of the comparator 3 is 'Hi' and the level of the signal Q of a D-FF 4 is 'Hi' and the level of the signal (q) of the D-FF 4 is 'Lo'. A transistor Tr1 is closed and the solar cell output is discharged through a resistor R3 and a transistor Tr 2 is opened and a motor 2 is in a resting state.  If the solar cell electromotive force is sufficient, the solar cell voltage is elevated and the output of the comparator 3 is inversed and the outputs Q and (q) of the D-FF 4 are also inversed. As a result, the discharge through the resistor R3 is cut off and, at the same time, the motor 2 is turned on and starts rotation.

Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To segment an image even without setting a segment symbol. SOLUTION: When a bar code is completely decoded, the coordinate of the upper left corner of a bar code image is calculated (S14 in figure 2). Next, on the basis of information concerning the recording position of the image of a signature or seal impression, the segment position of the image is calculated with the coordinate of the upper left corner of the bar code image as an origin and the image is segmented at that segment position (S15). A user can arbitrarily set the recording position of the signature or seal impression corresponding to the specification of a voucher or the like. Thus, the image of the signature or seal impression can be segmented together with the bar code even without setting the segment symbol.
