摘要： A discharge pulsation reducing cooler B is provided to cover the circumferential periphery of a compressor A. The discharge pulsation reducing cooler B has a delivery passage 41 and a jacket 43 covering that, and cooling water is circulated through a passage formed between the delivery passage 41 and the jacket 43. Delivered air flowing through the delivery passage 41 is cooled by the cooling water. In particular, because heat exchange efficiency is promoted by turbulence caused by the pulsation in the delivery passage 41, the delivered air is cooled efficiently. Also, pulsation is reduced in first and second expansion chambers 44, 45 in the delivery passage 41, and pulsation noise in the delivery passage 41 is reduced by the cooling water passage 42 and the jacket 43.

摘要： A compressor is composed of a pair of rotors engaging with each other and a driving mechanism having plural gears for driving the pair of rotors. The pair of rotors is disposed in a rotor chamber and the driving mechanism in a gear chamber, both chambers being separated by a separating wall. Fluid such as air is introduced into the rotor chamber from an inlet port and compressed therein, and the compressed air is delivered through an outlet port formed at a position close to the driving mechanism. A cooling water passage is formed at a bottom portion of the gear housing to cool lubricant encapsulated in a gear chamber. Additional cooling water passages may be made to further cool the components of the compressor.

摘要： Pulsation, vibration and noise of a screw compressor is caused by compressed air abruptly discharging through a discharge port in a rotor chamber during rotation of a pair of rotors. The inside opening shape of the discharge port is within two tip curved lines drawn by the pair of rotors and coincides with the two tip curved lines at least at one point when fluid starts to discharge. In one embodiment, the inside opening shape is triangular with a vertex at a point of intersection of the two tip curved lines and a base side along the discharge end face of the rotor chamber. With this, when the air compressed in the compression chamber discharges from the discharge port, the discharge opening area of the discharge port smoothly increases. This reduces the pulsation of the discharged air and thus reduces the vibration and noise of the screw compressor.
摘要翻译：螺旋式压缩机的脉动，振动和噪音是由一对转子旋转期间的压缩空气通过转子室中的排出口突然排出而引起的。排出口的内部开口形状在由一对转子拉出的两个尖端曲线内，并且至少在流体开始排出时的一个点处与两个末端曲线重合。在一个实施例中，内侧开口形状是三角形的，顶点位于两个尖端曲线的交点处和沿着转子室的排放端面的基底侧。由此，当在压缩室中压缩的空气从排出口排出时，排出口的排出口面积平滑地增大。这减少了排出的空气的脉动，从而减少了螺杆式压缩机的振动和噪音。

摘要： In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.

摘要： A peak voltage detector circuit detects a peak voltage of an input voltage. The input voltage is input into a first input terminal of a comparator. A counter circuit counts up a counter value in synchronization with a first clock signal, when a signal output from the comparator is in a first state. The counter circuit counts down the counter value in synchronization with a second clock signal. A digital-analog conversion circuit outputs an output voltage corresponding to the counter value, and the output voltage is input into a second input terminal of the comparator. The first clock signal has a wave period shorter than that of the second clock signal.
