摘要： PURPOSE:To contrive to miniaturize an oil separator and consequently enable to miniacurize a compressor by a structure wherein grooves, which require no space, are arranged on the inner wall of a chamber in order to improve the oil separation efficiency of the oil separator in the compressor. CONSTITUTION:Compressed gas containing oil droplets therewithin passes through a hole 34 formed in the vicinity of the center of a grooved plate 26 and flows between grooved plates 26 placed one upon another at intervals in the direction normal to the grooves 35 of each plate 26 in the oil separator with a construction, in which a plurality of the grooved plates 26 and a cover 27 are fixed to a rear plate 2 by means of a bolt 28 within the chamber 11. The oil droplets grow larger while the gas passes between the grooved plates 26 and fall down by gravity in order to be stored in an oil reservoir (not shown). On the other hand, oil mist, the oil droplets of which are not completely separated from gas, are caught by the grooves 35 arranged on the inner wall of the chamber 11, resulting in further improving the oil separation efficiency and accordingly enabling to miniature the oil separator and consequently the compressor.

摘要： PURPOSE:To prevent a tangential seal section from seizure or burn in the bud by arranging a ring-like oil groove and injection oil grooves on the sliding face of a rear plate and by feeding oil positively to the tangential seal section so as to cool a rotor. CONSTITUTION:A part of back pressure oil flows into a ring-like oil groove 26 arranged on the sliding face of a rear plate 3; flows out toward the periphery of a rotor along the rotating direction L of the rotor due to the back pressure, centrifugal force, and inertia; and flows out positively toward points M which are the intersections of a tangential seal section 28 and the rear plate 3. Thereby, the rotor overheated by the vane sliding friction heat is cooled at the ring- like oil groove 26 portion by means of the oil circulated toward the rotating direction L of the rotor, thus occurrence of a seizure phenomenon caused by a difference in thermal expansion can be prevented.

摘要： PURPOSE: To lessen fluctuation of drive torque by forming a sectional curve line representing the inner wall of a cam ring with a nonsymmerical shape and by shifting the most radially expanded portion to the air suction nozzle side.
CONSTITUTION: A sectional curve line representing the inside wall of a cam ring 38 is formed into a nonsymmetrical shape, and the most expanded portion of the cam ring 38 is shifted the air suction nozzle side. With this construction, when the air having the same volume is compressed to the same discharge pressure, work can be done over a large angle of revolution of a drive shaft. Therefore, the drive torque is made flat, thereby lessening flactuation of the drive torque.

摘要： PURPOSE:To miniaturize a crank mechanism by a method wherein the arm length of a member connecting a crank shaft with a crank pin is equalized to the arm length of a member connecting the crank pin with a piston. CONSTITUTION:The arm length of the 1st member 3 connecting the crank shaft 1 with the crank pin 2 is equalized to the arm length of the 2nd member 4 connecting the crank pin 2 with the piston 5. Thus, the stroke of the piston 5 obtained by one revolution of the crank pin 2 can be almost doubled as before. When the stroke is of the same length as before, the arm length of a crank mechanism can be made about a half as before and the crank mechanism can be miniaturized further.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult for a linear actuator to perform an accurate positioning by accumulating unidirectional motions out of reciprocating motions by means of a reciprocating driving source because an output shaft is shifted by an external force when it is driven in the actuating direction of the external force; furthermore its wedge connection tends to a bottleneck in durability because the linear actuator has larger pressure on its contact surface due to point contact; and a complicated part shape causes an economical barrier to a low cost in trying to lower pressure on contact surface by changing configuration from point contact to linear contact. SOLUTION: A constitution is designed to install an intermediate output shaft and a final output shaft driven by it, to directly drive the intermediate output shaft by the reciprocating driving source through the wedge connection, and to drive the final output shaft by the intermediate output shaft after another wedge connection is released which has locked the final output shaft by its translatory motion. Further, the part shape to constitute the wedge connection is changed to be capable of mutual linear contact even if it is entirely the shape of rotating body, or capable of allowing a long range in the linear contact.

摘要翻译：要解决的问题：为了解决线性致动器难以通过由往复运动驱动源往复运动而累积单向运动而进行精确定位的问题，因为输出轴由外力移动当其在外力的致动方向上被驱动时; 此外，由于线性致动器由于点接触而在其接触表面上具有较大的压力，所以其楔形连接趋向于耐久性的瓶颈; 并且复杂的部件形状通过将配置从点接触改变为线性接触而在试图降低接触表面上的压力方面导致成本低廉的障碍。解决方案：一种构造被设计成安装由其驱动的中间输出轴和最终输出轴，以通过楔形连接件通过往复式驱动源直接驱动中间输出轴，并且通过中间输出轴经另一个楔形连接被释放，其通过其平移运动锁定最终输出轴。此外，即使构成楔形连接的部件形状完全为旋转体的形状，也能够允许线性接触的长距离，能够进行相互线性接触。版权所有（C）2009，JPO＆INPIT
