摘要： A zoom lens system comprises from object side to image side, a front lens unit of a negative refractive power and a rear lens unit of a positive refractive power with a variable air space, which changes in the zooming operation, formed between the front and rear lens units. The rear lens unit consists of a first biconvex lens element, a second biconcave lens element and a third biconvex lens element. Futher, an aperture diaphragm, which is arranged between the front and rear lens units or at the image side next to the rear lens unit, is stationary on the optical axis of the lens system in the zooming operation. In a 2-components zoom lens system having a negative lens unit and a positive lens unit from object side according to the present invention, a zoom ratio of about 2 and a sufficiently long back focal length can be obtained in spite of a small number of lens elements. Moreover, cost reduction, compactness and a high performance in the whole lens system including the aperture diaphragm and a lens barrel are obtainable.

摘要： A safer power supply is used in conjunction with a system for preserving food, oil, organs, or other organic material. The power supply constantly applies a high voltage-weak pulse electric voltage, generated by a transformer using an alternating-current power supply of commercial frequency, with the voltage applied through an electrically conducting electrode to the food or other organic materials. In the power supply, one pole of the secondary winding is sealed for increased safety. By applying or impressing high voltage-weak pulse electric current to frying oil or other organic materials using the power supply and/or the preservation system, the high voltages restrain deterioration of frying oil and enables long-term use. Installed on a food container which is placed in a refrigerator, the power supply safely applies high voltage-weak pulse electric current to meat and fish in the container, and so suppresses propagation of germs and deterioration.
