摘要:
The present invention provides an information recording apparatus capable of reproducing recorded recording information without giving strange feeling even in the case where it is necessary to switch a recording layer among multiple recording layers, and an information recording program for executing the information recording process.An information recording apparatus R for recording “recording information Sr” to an optical disk DK having a plurality of recording layers L0 and L1 has a CPU 4 for detecting the content of the recording information Sr during recording of the recording information Sr to the recording layer L0, on the basis of the detected content, switching the recording layer L0 to which the recording information Sr is switched to the recording layer L1, and continuing recording of the recording information Sr.

A sewing machine including a maintenance information storage that stores maintenance information; an alert element that communicates maintenance information; a cumulative data storage that stores cumulative data of at least either of a sew time or a stitch count; a determiner that determines whether or not a predetermined timing for communicating the maintenance information has been reached based on the cumulative data; an alert count storage that stores an alert count of the maintenance information communicated; and an alert controller that, when determined by the determiner to have reached the predetermined timing for communicating the maintenance information, controls the alert element to communicate the maintenance information for a predetermined number of times based on the alert count.

A heat exchanger includes tubes and a tank. The tubes extend in a first direction, and are stacked in a second direction. The tank has a tube insertion plate part, and is arranged at an end portion of the tubes. The tube insertion plate part has tube holes in which the tubes are inserted, and ribs extending in a third direction that is approximately perpendicular to the first direction and the second direction. The tube hole has end portions in the third direction. The rib are arranged to overlap with the end portion of the tube hole in the second direction, and to provide a deformable part to be deformable in the first direction. The deformable part is located in the tube insertion plate part outside of the ribs in the third direction.

A sewing machine and a method for managing manufacture of the sewing machine that effectively utilize production information in a manufacture process or a repair process of the sewing machine. The sewing machine may include a stitch formation device that forms stitches in work cloth by relatively moving the work cloth with respect to a vertically moving needle; a display device that displays a record of performing an operational test, in which operations of the sewing machine are adjusted or confirmed, the operational test including test items; and a performance record storage device that stores the performance record, the performance record being correlated with the test items of the operational test.
摘要:
When a stitch data compensation device detects that a control code which indicates a movement of a work cloth is added to the current and next stitch data, it corrects an X-direction movement amount and a Y-direction movement amount for the current stitch data according to an angle between a stitch to be formed based on the current stitch data and a consecutive stitch to be formed based on the next stitch data. When sewing is made on a sewing machine using the stitch data corrected by the stitch data compensation device, the shrinkage of the work cloth that would occur due to each stitch sewn thereinto can be prevented, which will result in preventing an uneven finished pattern, such as a gap in a satin pattern, a jagged fill pattern, and stitches to be made on the return when the sewing direction is reversed deviating from the ones already made on the go when running stitching is selected, assuring fine stitches will be formed on the work cloth.

A sewing machine includes a sewing machine motor that vertically drives a sewing needle via a main shaft; a sewing speed commander that produces a command sewing speed determined by rotational speed of the sewing machine motor; a stitch-pitch specifier that specifies a stitch pitch to be applied to manually fed sewing operation; a consumed thread amount detector that detects a consumed needle-thread amount in each ongoing sewing cycle; a sewing speed controller that controls sewing speed at the command sewing speed when the command sewing speed is equal to or less than a predetermined reference sewing speed, and that controls sewing speed at a target sewing speed calculated based on the consumed needle-thread amount and the stitch pitch when the command sewing speed is greater than the reference sewing speed.
摘要:
A heat exchanger comprising: a core portion including a plurality of tubes; a pair of header tanks communicating with the tubes; and a pair of inserts arranged substantially parallel to the length of the tubes, and in such a manner as to contact the core portion at the ends of the core portion to transfer the heat from the core portion, and having the ends thereof supported on the header tanks; wherein a stress absorber to absorb the stress generated along the length of each insert is formed in the insert; wherein the stress absorber is formed over each insert from the upstream side to the downstream side in the air flow; and wherein the stress absorber is arranged in such a manner that the most upstream end and the most downstream end thereof in the air flow are not superposed, one on the other, along the direction of air flow.

The sewing machine includes a presser foot that is lowered to press a workpiece cloth; a presser foot lifting lever operating the presser foot; a thread tension mechanism including a thread tension regulator capable of adjusting the thread tension of a needle thread and opening the thread tension regulator based on the lifting operation of the presser foot lifting lever; and a thread guide groove guiding the needle thread at least to the thread tension mechanism, upon carrying out the thread hooking work. The sewing machine further includes a detector detecting a lifting operation of the presser foot lifting lever; a covering member which is movable between a closed position where the covering member covers at least a part of the thread guide groove and an opened position where the covering member opens the thread guide groove. The covering member is moved to the closed position when the presser foot is in a lowered state. An actuator moves the covering member at least from the closed position to the opened position. A controller controls the actuator so that the covering member is moved to the opened position when the detector detects the lifting operation of the presser foot lifting lever.
摘要:
In a presser foot device of a sewing machine, a presser foot is vertically movably supported to a sewing machine body frame by a presser bar. A drive device moves the presser bar up and down in accordance with a drive signal. A sensor detects when the presser foot is raised close to a top dead center position, that is, a predetermined position. Based on the detection by the sensor, a control device controls the drive signal for the presser foot drive device.
