摘要:
A light transmission apparatus in which light from a laser may be transmitted through an optical conducter. Dry air may also be pumped through the optic conducter to remove matter from the vicinity of the light emitting end. A cover which is formed of a shape memory alloy is provided at the light emitting end of the conductor to open at a high temperature in response to incident light and close at a low temperature when the light stops.

A needle oscillating mechanism for use in a sewing machine is disclosed, wherein a rotatable cam member is provided for controlling the position of lateral oscillation of a needle, and a contact finger engaged with the cam member or disengaged therefrom synchronously with rotation of a main shaft of the sewing machine is coupled to the needle through a disconnectable coupling means. Disengagement of the contact finger from the cam member is not transmitted to the needle due to disconnection of the coupling means, so that the needle is held at the same lateral position by the action of brake means. Posterior to rotation of the cam member with the contact finger kept disengaged therefrom, engagement of the contact finger with the cam member is effected while causing connection of the coupling means, thereby shifting the needle to a lateral position in response to the cam surface of the cam member with which the contact finger is engaged.
摘要:
A system is disclosed in which a first information carrying member with multiple pieces of bight information recorded thereon to control the position of lateral oscillation of a needle, and a second information carrying member with multiple pieces of feed information recorded thereon to control the length and direction of feed movement of a feed dog are driven individually by a single step motor with a substantially fixed phase difference in timed relation to rotation of the main shaft of a sewing machine. One information carrying member is secured to the output shaft of the step motor, while the other information carrying member is fitted thereto loosely. Holding means normally functions to hold the two information carrying members at given relative angular positions, and permits said other information carrying member to rotate relatively to said one in both forward and reverse directions from said given angular position within a predetermined angular range. Blocking means temporarily prohibits rotation of said other information carrying member in timed relation to rotation of the main shaft of the sewing machine, and in such a state, said one information carrying member is rotated alone by the step motor within said predetermined angular range. And after interruption of the action of the blocking means, the other information carrying member is rotated alone to the given angular position relative to said one information carrying member.

An information display apparatus for a sewing machine is disclosed which comprises an information memory means storing various instructing information on how to use the sewing machine, explanatory information explaining the method of sewing each of a plurality of stitch patterns and the like, an information selecting means, a liquid crystal display of multirow-multicolumn dot-pattern type, and a display controlling means, and is constituted so as to be able to display the above-mentioned various information by characters and images.
摘要:
Optimum sewing machine setting values for a plurality of stitch patterns to be adjusted by adjusting means, and display information data of messages explaining at least either the manner of sewing operation for the stitch patterns or methods of forming the stitch patterns are stored in a memory at addresses respectively corresponding to the stitch patterns. Relevant setting values are displayed when a stitch pattern is selected on a display unit and the indication of the setting values is changed for the indication of a message when a changeover member is operated.
