Abstract: A charging device which is capable of preventing charging current from flowing even if a battery pack remains mounted thereon after charging of the battery pack is completed, thereby preventing deterioration of batteries of the battery pack. A circuit including a semiconductor switch generates a DC power for charging the battery pack. A backflow prevention diode is connected between the semiconductor switch and the battery pack. When charging of the battery pack has been completed, a secondary charge control circuit causes a DC voltage input to the backflow prevention diode to be made lower than the voltage of the battery pack.

Abstract: When charging current is switched, the output voltage from the solar cell, namely an input voltage to a charging apparatus, changes, and controlling the input voltage to the charging apparatus does not operate correctly. Furthermore, when charging current decreases in response to a drop of the output voltage from the solar cell, a fully-charged state of the secondary cell is erroneously detected. Still further, when the charging operation is completed in accordance with a timer after charging the secondary cell by a small charging current, the secondary cell is not fully charged. To correct these problems, the input voltage Vin is compared to a voltage value V1, and, if a state in which Vin is higher than V1 (Vin>V1) is moved to a state in which Vin is equal or lower than the V1 (Vin.ltoreq.

Abstract: An automatic bread-making device comprises a housing, a cooking vessel removably arranged therein and provided at its bottom with a rotating shaft, a kneading blade removably attached to the rotating shaft, and a driving means for rotating the kneading blade through the rotating shaft. The kneading blade is providing with at least one crescent-shaped projection at a wall surface of a bore for attachment of the blade to the rotating shaft, while the rotating shaft is provided at its upper portion with at least one groove extending in the direction parallel to a line which intersects the axis of the shaft to form a head with a figure similar to that of an opening formed between the inner wall of the bore and a free end of the projection. The kneading blade is attached to the rotating shaft so that the head of the rotating shaft is engaged with the projection of the blade when the head of the shaft is arranged in the bore of the blade.

Abstract: A process for producing a propylene block copolymer by a three-step reaction in the presence of a stereoregular catalyst. At the first step, propylene is polymerized at a temperature of 55.degree. C. or more to form polypropylene having an intrinsic viscosity of from 0.5 to 3.5 in the prescribed amount. At the second step, propylene is polymerized at a temperature of from 30.degree. to 90.degree. C. to form polypropylene having an intrinsic viscosity of at least 4 in the prescribed amount. And at the third step, ethylene and propylene are copolymerized at a temperature of from 30.degree. to 90.degree. C. to form an ethylene-propylene copolymer having an intrinsic viscosity of at least three in the prescribed amount. The propylene block copolymer formed by the three steps is superior and well balanced in impact resistance and stiffness.
