  • Publication number: 20190049464
    Abstract: Novel means capable of detecting an arteriosclerotic lesion in a body by a less invasive, simple method is disclosed. The method for detecting arteriosclerosis according to the present invention comprises measuring the myosin heavy chain 11 level in a blood sample isolated from a subject. A myosin heavy chain 11 level higher than that of a healthy individual is indicative of the presence of arteriosclerosis in the subject. Since the present invention enables detection of arteriosclerosis by a blood test, a less invasive, simple test can be carried out. Unlike methods for testing only particular regions such as carotid artery ultrasonography, the present invention is expected to reflect the conditions of blood vessels in the whole body.

  • Patent number: 6244061
    Abstract: When inverter control is implemented in a refrigerator or the like, the rotating speed of a compressor motor is often operated at the preset minimum rotating speed. At this time, there has been a problem that when the DC voltage is boosted, the efficiency of the circuit drops due to switching loss in the power element. Still more, when the DC voltage is boosted even at the minimum rotating speed, the lowest voltage of the DC voltage must be controlled at 163 V or more including the fluctuation of the voltage. Therefore, there has been a problem in that the efficiency of the compressor motor also drops.

  • Patent number: 6002220
    Abstract: A high-efficiency, compact and low-cost electric power storage air-conditioning system incorporates inside its air-conditioner an electric power storage unit including a battery which is electrically interconnected to a d.c. system of the air-conditioner. Charging of the battery is controlled to be executed only during a steady operation of the air-conditioner when its load is light. Since a d.c. voltage of the battery is used directly as a d.c. voltage to drive the air-conditioner, a high efficiency, minimized loss and economical operation conditioning system is achieved.
