摘要： PROBLEM TO BE SOLVED: To improve chip discharging ability while attaining high accuracy machining by reducing machining load.
SOLUTION: In this grinding wheel 50 with abrasive grains 53 fixed to the circumferential surface of a cylindrical base metal 51, the abrasive grains 53 are spirally arranged on the abrasive grain fixing surface of the base metal 51 to reduce the number of abrasive grains, and the abrasive grains 53 are exposed to laser beams to uniformize the height of the abrasive grains 53. Truing is applied by the irradiation of laser beams to uniformize the height of the abrasive grains, and a groove is formed on the abrasive grain fixing surface by laser irradiation.

摘要： PROBLEM TO BE SOLVED: To provide a laser regulating method and device for a flat grindstone capable of truing the flat grindstone in which abrasive grains are fixed to a flat surface part of a base seat.
SOLUTION: In this method for regulating the flat grindstone 1 in which the abrasive grains 1d are fixed to the flat surface part 1c of the flat base seat 1b by binding agent 1e to expose their head parts, a relative angle between an optical axis 21c of a laser beam 21b that is focused and the flat surface part 1c is set in such a way that an incidental angle D of the laser beam 21b becomes a prescribed angle larger than a focused angle E of the laser beam 21b, and the laser beam 21b is radiated in such a way that a focal point F falls to a height T of the exposed head parts of the abrasive grains 1d.

摘要： PROBLEM TO BE SOLVED: To prevent reverse flow of gas refrigerant having high temperature and high pressure toward an evaporator disposed on a low pressure side, and improve an efficiency and reliability of a compressor by holding an inside of a tightly closed space for housing a compression mechanism part having a driving shaft for revolting a piston and an electric motor for rotating the driving shaft, to an intake pressure atmosphere. SOLUTION: A rotary compressor is composed of an electric motor part (a) which consists of a stator 1 and rotator 2, and a compression mechanism part (b) driven by the electric motor part (a), they are housed in a hermetic container 13, and is directly attached to the hermetic container 13. In this case, the inside of the enclosed container 13 is held to an intake pressure atmosphere. Accordingly, it is solved that gas coolant having a high temperature and high pressure is made flow in the reverse direction from each contact surface between a cylinder 5 of the compression mechanism part (b), and a frame and a cylinder head toward a low pressure side where an evaporator 36 is disposed, and the temperature of a cooler is prevented from raising without arranging a check valve and the like in a circuit. Simultaneously, a blade motion space of the cylinder 5 is communicated with the inside of the enclosed container 13 so as to reduce sliding loss of the blade.

摘要： PROBLEM TO BE SOLVED: To ensure the passage area of a discharge port without extending the diameter of the discharge port to reduce the pressure loss by bringing the discharge port for a compressed fluid into contact with the side surface of a blade oscillated most to a compression chamber side, and arranging it on at least either one of a frame and a cylinder head in a specified position. SOLUTION: A piston 5 revolves along the inner wall of a cylinder chamber in a cylinder 4 so as to oscillate with the central point on the circumferential surface of a guide 28 as a fulcrum through a blade 501, and compress and discharges a fluid through a discharge port 301. The discharge port 301 is arranged in a position where it makes contact with the side surface of the blade 501 in the maximum rocking angle to the compression chamber 402a side, when axially seen, and the inside surface of the cylinder chamber. Namely, the discharge port 301 is arranged in the position where the distance from the center of the cylinder 4 to the center of the discharge port 301 corresponds to the value obtained by subtracting the discharge port radius from the cylinder inside radius. According to this, the discharge port 301 is prevented from being blocked by the blade 501 in the first half of the discharge stroke to reduce the passage area.

摘要： PROBLEM TO BE SOLVED: To prevent a moment from acting on a piston and to prevent sliding loss by making approximately the center of the effective length of a bearing part constituted of a contact part between the internal circumferential face of the piston and the outer circumference of an eccentric shaft of a drive shaft coincide with the center of the cylinder length. SOLUTION: When a piston 6 revolves along the inner wall of a cylinder chamber 4a in such a state as swinging with the rotation center position of a guide set to a fulcrum via a blade by the rotation of a drive shaft 5, a refrigerant gas sucked from a suction port is compressed and discharged from a discharge port. In this case, relieves 5f of equal length (a) are formed in top/bottom both end faces 5b, 5c of an eccentric shaft 5a of the drive shaft 5. Where the cylinder height is set to H, the effective length Lb of a bearing part constituted of a contact part between the internal circumferential face 6g of the piston 6 and the outer circumferential face of an eccentric shaft 5a of the drive shaft 5 is formulated Lb=H-2a and the central position of the effective length Lb of the bearing part is set to (1/2)H.
