Abstract: This invention provides a scroll type fluid machine which can simultaneously realize the stabilization of the behavior in the rotational direction of an orbiting scroll and the reduction in the manufacturing cost by the ease of holding a grease. In the scroll type fluid machine, three pairs of rotation prevention mechanisms are provided between a casing and an orbiting scroll. The rotation prevention mechanism is constituted of first and second ball coupling mechanisms having a function different from each other. The first ball coupling mechanism supports the thrust load of the orbiting scroll. Meanwhile, the second ball coupling mechanism supports the rotation force of the orbiting scroll.

Abstract: Provided is an information processing apparatus including an acquisition unit, a reproduction unit, an input unit, and a control unit. The acquisition unit obtains, of moving image data including images of pages having serial page numbers and an image of motion of turning the pages one by one in order of the page numbers, first moving image data in which a page time being a time on the moving image data is assigned to each page. The reproduction unit reproduces the first moving image data, generates a moving image, and displays the moving image on a display screen. The input unit receives a designation of a second page different from a first page of the first moving image data currently displayed on the display screen. The control unit calculates a page time difference therebetween and controls a reproduction speed of the first moving image data depending on it.

Abstract: In a seal system for a scroll type fluid machine, a seal mechanism is provided between a backpressure plate and a holder, so as to surround an orbiting backpressure chamber. The seal member comprises a seal attachment groove, a seal member and a Y-shaped packing. The seal attachment groove is stepped on its outer circumference to define a shallow bottom portion. The seal member includes, on its outer circumference side, a cutout portion matching the shallow bottom portion. The Y-shaped packing is disposed between a deep groove peripheral wall of the seal attachment groove and the cutout portion of the seal member, and a backpressure chamber is defined on a reverse surface side of the seal member. By this arrangement, a slide surface of the seal member can be larger than an effective area of the backpressure side of the seal member. Thereby it is possible to reduce a difference between a load Ff acting on the slide surface and a load Fb acting on the reverse surface.

Abstract: To provide a higher sealing capability irrespective of the pressure difference between compression chambers, lips having leading ends extended toward the inner surface of a recessed groove are formed. At least some of the lips have a base end that is shaped to reduce rigidity against extension of the lips.

Abstract: A disc brake that suppresses braking noises when a vehicle moves backward include an urging spring urging a friction pad toward a rotationally exiting side of a disc when the vehicle moves forward, the urging spring being arranged between a hook portion of the friction pad and a torque receiving portion of a carrier. The urging spring formed through bend of an elastic plate material has its spring constant that is set to be a small value to avoid resonance frequency causing noise where the base end side thereof is fixed to the hook portion of the backing plate while the top end side thereof elastically abuts to the torque receiving portion of the carrier. The urging spring is located at the position that is outside in the radial direction from the center position of the hook portion in its width direction.

Abstract: Durability of a seal member is improved by reducing a surface pressure thereon. A seal mechanism 24 is provided between a backpressure plate 16 and a holder 17 so as to surround an orbiting backpressure chamber 18. The seal member 24 comprises a seal attachment groove 25, a seal member 26 and a Y-shaped packing 27. The seal attachment groove 25 is stepped on its outer circumference side to define a shallow bottom portion 25B. The seal member 26 includes, on its outer circumference side, a cutout portion 26D matching the shallow bottom portion 25B. The Y-shaped packing 27 is disposed between a deep groove peripheral wall 25C of the seal attachment groove 25 and the cutout portion 26D of the seal member 26, and a backpressure chamber 28 is defined on a reverse surface 26B side of the seal member 26. By this arrangement, a slide surface 26A of the seal member 26 can be larger than an effective area of the backpressure side of the seal member 26.

Abstract: The present invention provides a scroll type fluid machine which enables both of a fixed scroll and an orbiting scroll to be cooled by means of a cooling fan, and which enables an overall size of the machine to be compact. Cooling fans 38A and 38B are connected to a rotary shaft 18 between an electric motor 15 and orbiting scrolls 26A and 26B. Outer cases 3A and 3B are provided with flow inlet openings 42A and 42B, flow outlet openings 43A and 43B, scroll ducts 44A and 44B and cooling device ducts 46A and 46B. Compression portions 6A and 6B are operated by rotatably driving the rotary shaft 18 using the electric motor 15. In this instance, the cooling fans 38A and 38B are rotated with the rotary shaft. Therefore, with a simple structure having no electric fans, the fixed scrolls 7A and 7B, the orbiting scrolls 26A and 26B and the cooling device 47 can be efficiently cooled, and a compressor having a compact size and a high cooling performance can be formed.

Abstract: Inner peripheral projections are provided on the inner peripheral surface of a wrap portion of an orbiting scroll member, and outer peripheral projections are provided on the outer peripheral surface of the wrap portion. The inner and outer peripheral projections each have an approximately triangular transverse sectional configuration defined by a narrow top of the projection and a pair of concavely arcuate surfaces extending with a wide overall width so that the projections can prevent stress concentration with the concavely arcuate surfaces to increase the mechanical strength and can be readily machined by using a tool, e.g. an end mill. When contacting the mating wrap portion, the narrow tops of the projections are readily crushed or worn. Therefore, the tops of the projections can become fit to the wrap portion without strongly contacting it many times.
