摘要： A safety control device for a speed control circuit of a commutator motor having an ignition circuit includes a circuit for detecting an armature current and defining whether the commutator motor is energized with a supply current or with a free wheel current, a maintaining circuit for discriminating if the detected result is a continuously energized condition or an intermittent condition, and a bistable circuit. The maintaining circuit smoothes the detected voltage of the energized motor and maintains the voltage over at least one cycle of the power source and functions temporarily in an equivalent manner of continuous energization of the motor when power source is applied to the motor. The bistable circuit nullifies the ignition circuit of the motor control when the motor is in an intermittent energization and switches the ignition circuit into an effective condition as the maintaining circuit comes to accumulate the voltage above the predetermined level while no speed designation is made to the speed control circuit of the motor.

摘要： There is a zigzag sewing machine provided with a horizontal rotary loop taker device which is restrained with respect to the rotation direction, and holds therein a bobbin carrier horizontally attached, and is supplied with a lower threads from the left side to the left basic line marked with an axial line in front of the needle, and provided with a feed dog which is provided nearly to passage of the needle to move vertically and laterally. In such a sewing machine a cam portion is provided for supplying the lower thread to a lower thread contacting portion of the bobbin carrier or a lower thread contacting portion of a part connecting right and left teeth of the feed dog, whereby the amount of supplying the lower thread is adjusted properly with respect to the left basic line and the right basic line during zigzag stitching, and the slack amount of the lower thread is adjusted properly with respect to the left basic line and the right basic line during forming stitches. A cam portion is provided to the lower thread contacting portion of a needle plate for guiding the lower thread to change the passage of the lower thread, whereby the slack amount of the lower thread may be adjusted properly with respect to the left basic line and the right basic line during forming stitches, and the lower thread of the zigzag stitch is made pretty on a rear side of the sewn fabric.

摘要： A single motor controls needle swing and fabric feed in a sewing machine. The motor is connected to a transmission which alternately locks either the needle swing or the fabric feed while releasing either the fabric feed or the needle swing as the case may be. The motor is operated in accordance with a predetermined program by an electronic control system. Multiplexers are used in order to alternately transmit feed data and needle control data to the motor. Two embodiments are taught: one embodiment being purely digital in nature, and the other embodiment including an analog feedback loop.

摘要： A camera apparatus comprises a cabinet having an outwardly reflecting half-silvered mirror 5 in its front wall and providing behind the mirror a chamber into which light can enter only through the mirror, and a camera 10 in the chamber arranged to photograph an image passing through the mirror. The distance between the lens and the film or other image focussing surface is fixed for focussing on a person positioned in front of the mirror and able to view himself in the mirror. Twin lenses 14 allow two side-by-side images to be produced on film 13 which may be of a rapid processing type.

摘要： A loop catching device for a sewing machine includes a rotatable loop taker carrying a lower thread, a pulse motor operated in a timed relationship with a reciprocating movement of a needle, and a looper arranged adjacently to the loop taker and driven by the motor. The loop taker and the looper are synchronized with the movement of the needle to catch the loop produced by the needle and hold the loop for a predetermined time.

摘要： Intercharacter data for use in an electronic sewing machine is prepared by the steps of constituting each intercharacter control data with a first stitch control data group for determining relative position between a fabric and a character, a second stitch control data group utilized to form the character, and a third stitch control data group for determining a spacing between adjacent two characters; drawing a top segment alpha and a bottom segment beta respectively passing through top and bottom portions of the characters in parallel with the fabric feeding direction; and drawing a front segment X and a rear segment Y respectively passing through mostly projecting portions of the character on the front and rear sides thereof with respect to the fabric feeding direction in perpendicularly to the segments alpha and beta . Then the needle position of a first stitch point effected by the first stitch control data group comes to a position near the segment X and the area (Sh') of a front blank portion bounded by a segment X0' passing through the first stitch point in parallel with the segment X, the contour of a character to be stitched next, and the segments alpha and beta is substantially the same between any two adjacent characters. Moreover, the area (St') of a rear blank portion bounded by a segment Y0' passing through a last stitch point provided by the third stitch control data group in parallel with the segment Y, the contour of a previously stitched character and the segments alpha and beta are also substantially the same between any two adjacent characters.
