摘要： In the improved thermal recording method in which image data supplied from an image data supply source are subjected to specified image processing jobs and in which a thermal head is driven in accordance with the processed image data so as to perform thermal recording, image processing jobs are performed in a specified order such that sharpness correction and tone correction are followed by shading correction and correction of resistance values which, in turn are followed by compensation for temperature elevation, provided that calculation treatment of respective values of the image data for the compensation for temperature elevation is performed either prior to or after either one of the corrections that are performed subsequent to the tone correction. It is preferred that black ratio correction and/or load variation correction are also performed after the shading correction and the correction of resistance values, and prior to the compensation for temperature elevation. The improved thermal recording apparatus is used to carry out the thermal recording method described above. According to these apparatus and method, high quality images can be recorded consistently.

摘要： A pipe joint comprises a pair of tubular joint members, an annular gasket interposed between abutting end faces of the joint members, and a nut for joining the joint members. A seal projection is formed on the abutting end face of each joint member at a position radially outward of an inner periphery of the end face. When an end of the seal projection is brought into contact with an end face of the gasket by tightening the nut, a clearance is formed between an outer flat portion of the abutting end face of each joint member and the gasket end face opposed thereto. The clearance is greater than a clearance between an inner flat portion of the abutting end face of each joint member and the gasket end face opposed thereto, and is eliminated when the nut is completely tightened up.

摘要： In a power converting apparatus having a plurality of phases on an AC side and configured to perform conversion between DC power and AC power, a current detector detects currents flowing through a DC source line through which a plurality of phase currents commonly flow. A control unit sets a current detection period and a succeeding current control period in each successive control cycle. Using first gate signals based on reference gate signals for PWM control, the control unit calculates values of the individual phase currents from the first gate signals and the detected currents during the current detection period. Then, during the current control period, the control unit performs PWM control using phase voltage commands generated by correcting phase voltage target values so as to cancel out voltage errors that occur during the current detection period.
