    • Aspects of the invention provide a projector capable of comparatively easily achieving a contrast ratio higher than the original contrast ratio of the liquid-crystal light valve by a simple mechanism. The illumination light modulated by liquid-crystal light valves, i.e., image light, can be combined together in a cross dichroic prism, and then light intensity of suitable pixels is reduced by a proper amount by a liquid-crystal light valve, and then sent to a projection lens. The image light entering the projection lens can be projected to a projection surface. Because the light intensity of the image light formed by the liquid-crystal light valves is appropriately attenuated at suitable pixel areas by the liquid-crystal light valve, image light projection with a contrast ratio exceeding by far the contrast ratio achievable by the liquid-crystal light valves alone is possible due to cumulative light-intensity adjustment.
    • 本发明的一个方面提供一种能够通过简单的机构相对容易地实现比液晶光阀的原始对比度高的对比度的投影仪。 由液晶光阀调制的照明光,即图像光可以在十字分色棱镜中组合在一起,然后通过液晶光阀将适当像素的光强度降低适当的量,然后发送 投影透镜。 进入投影透镜的图像光可以投影到投影面。 由于由液晶光阀形成的图像光的光强度在适当的像素区域被液晶光阀适当地衰减,所以对比度超过液晶可实现的对比度的图像光投射 由于累积的光强度调节,单独的光阀是可能的。

    • A massage machine using a small size and high torque brushless DC motor includes a driving unit moved up and down along guide rails of a chair and a first motor for moving the driving unit up and down. A pair of treatment head bases are driven reciprocally in opposite directions to each other; and a second motor reciprocally drives the treatment head bases in opposite directions to each other. Treatment heads are respectively supported by the treatment head bases; and a third motor drives the treatment heads in a plane substantially perpendicular to a backrest. A control circuit drives the respective motors respectively independently of one another. Each motor is a brushless motor. A control circuit corrects, corresponding to a load imposed on the brushless DC motor, a waveform of a drive signal applied to a winding of the brushless DC motor so as to allow a current flowing through the winding of the brushless DC motor to have a substantially sinusoidal waveform making it possible to reduce discomfort due to motor noise, and to accurately control the motor rotation speed.
