    • A transcoding apparatus includes: a decoding unit for decoding a first bit stream; a bit allocation unit for estimating a bit count that can be used during encoding; a quantization parameter calculating unit for calculating a candidate quantization parameter according to the estimated bit count; a quantization parameter adjuster for determining a second quantization parameter according to the value of the candidate quantization parameter and for determining a ratio of the second quantization parameter to a first quantization parameter; and a bit shifting unit for performing bit shifting of decoded data according to the ratio. The quantization parameter adjuster sets a first critical value, the size of which is equal to twice the first quantization parameter. When the candidate quantization parameter is not smaller than the first threshold value, the second quantization parameter is set to be the same as the first critical value. When the candidate quantization parameter is smaller than the first threshold value, the second quantization parameter is set to be the same as the first quantization parameter.

    • One objective of the present invention is to provide an electronic component mounting system and an electronic component mounting method that can prevent a mounting defect due to a positioning error in the direction of the thickness of a substrate, and that can deliver a specific mounting quality. According to an electronic component mounting system, which is constituted by coupling a plurality of apparatuses used for mounting electronic components, the height measurement device 22 of a printing inspection apparatus measures the heights at height measurement points, designated on the upper face of a substrate, and outputs the measurement results as substrate height data. Then, once the substrate has been delivered to an electronic component placing apparatus, the substrate height measurement apparatus again measures the height of the substrate at specific height measurement points to obtain substrate height correction data, and based on the initial substrate height data and the substrate height correction data, updates a control parameter for controlling the component placing operation performed by a loading head. In this manner, discrepancies in the positions of the heights of individual substrates can be accurately corrected, and mounting defects due to positioning errors in the direction of the heights of the substrates can be prevented.

    • A hermetic compressor includes a hermetic container, a compression element accommodated in the hermetic container, and a motor element driving the compression element. The hermetic container has an inner space therein arranged to store lubrication oil. The compression element includes a shaft unit rotating about a rotation axis. The shaft unit has an oil-feeding passage provided therein. The oil-feeding passage extends upward from a lower end of the shaft unit. The shaft unit has an oil-spattering hole provided therein. The oil-spattering hole extends substantially perpendicularly to the rotation axis. The oil-spattering hole has a first open end communicating with the oil-feeding passage and a second open end opening in the inner space of the hermetic container. The second open end has a cross-sectional area smaller than a cross-sectional area of the first open end. This hermetic compressor supplies lubrication oil to sliding component, such as a piston, of the compression element, thus operating reliably and efficiently.
