20110067434 | HERMETIC TYPE COMPRESSOR AND REFRIGERATION CYCLE APPARATUS - As a hermetic type compressor, a motor portion and a compression mechanism portion that are coupled to the motor portion with a rotating shaft interposed therebetween are accommodated in a closed vessel. The compression mechanism portion comprises a cylinder that comprises an internal diameter hole, and a main bearing and a sub-bearing in which a bearing hole that journals the rotating shaft is provided and the internal diameter hole of the cylinder is closed to form a compression chamber in the compression mechanism portion. The main bearing and the sub-bearing have a circular groove that is opened toward the compression chamber side, an inner circumferential surface of the circular groove is tapered such that a diameter increases gradually from the compression chamber side toward an opposite side of the compression chamber side, and a depth of the circular groove is set to 40% of a diameter of the bearing hole. | 03-24-2011 |
20120174617 | REFRIGERANT COMPRESSOR AND REFRIGERATION CYCLE APPARATUS - A refrigerant compressor includes a compression unit having a roller and a vane for compressing refrigerant. The vane has a film having first to fourth layers on its metallic base member. The first layer is made of chromium. The second layer is made of chromium and tungsten-carbide. The third layer is made of metal-containing amorphous-carbon containing at least tungsten or tungsten-carbide. The fourth layer is made of non-metal-containing amorphous-carbon containing carbon and hydrogen. In the second layer, chromium content-rate on a first-layer side is larger than on a third-layer side, and tungsten-carbide content-rate on the third-layer side is larger than on the first-layer side. In the third layer, content-rate of the at least tungsten or tungsten-carbide on a second-layer side is larger than on a fourth-layer side. The roller with which an end-edge of the vane slidably-contacts is made of flake graphite cast iron containing molybdenum, nickel and chromium. | 07-12-2012 |
20130219952 | HERMETICALLY SEALED ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE - The height measured from the bottom surfaces of support legs is set to be 2.5 or more times as great as the outer diameter of the compressor body, the height of the center of gravity measured from the bottom surfaces of the support legs to the center of gravity is set to be ½ or less the overall height, and the support legs are provided in number of four, based on the fulfillment of Rc/cosθ08-29-2013 | |

20100321804 | LENS DRIVING DEVICE AND ELECTRONIC DEVICE - Provided is a lens driving device, including: a movable system including a lens frame to which the lens is fixed; a fixation system including a guide shaft inserted into a guide hole formed in the lens frame to allow the lens frame to advance and retract in an optical axis direction and a restricting member for restricting rotation of lens frame about the guide shaft; a lead screw, which is a substantially-shaft-like member rotatable with respect to the fixation system about an axis thereof substantially parallel to the guide shaft, and in which a male thread threadably fitted to the movable system is formed; a motor for rotating the lead screw about the axis thereof to allow the movable system to advance and retract along the lead screw; and a biasing member arranged in substantially parallel to the guide shaft, for biasing the lens frame in the axial direction and about an axis thereof. Thus, a lens driving device which are capable of performing accurate position adjustment of the lens frame in the optical axis direction with the small number of components without causing decentering about the lens frame to which the lens is fixed, and an electronic device provided with the lens driving device are provided. | 12-23-2010 |

20110019035 | IMAGE PICK-UP APPARATUS AND IMAGE PROCESSING METHOD - An image pick-up apparatus includes an image pick-up device, a noise reduction processing portion, and a level difference correction portion. The image pick-up device includes at least three kinds of color filters and photoelectric conversion elements formed under the color filters respectively. The noise reduction processing portion applies noise reduction processing to image pick-up signals output from the image pick-up device. The level difference correction portion executes correction to reduce a level difference between first and second ones of the noise reduction-processed image pick-up signals obtained from the photoelectric conversion elements formed under two color filters which are of the same kind but different in arrangement pattern of color filters arranged around the two color filters. The level difference correction portion changes correction strength in accordance with strength of noise reduction processing executed by the noise reduction processing portion. | 01-27-2011 |
