Patent JP-H05326196-A (JP)
Title: Undulator
Inventor: TAKANAKA MASAO
IPC: H05H7/04
Filed: 1992-05-22
Abstract: PURPOSE:To increase the wavelength variable ratio of an emitted light by emitting the emitted light in the advancing direction of an electron beam by the snaking motion of the electron beam, and changing the frequency of a super-high frequency electromagnetic wave to change the wavelength of the emitted light. CONSTITUTION:An electron beam 4 entered to a waveguide 1 by a deflecting magnet 3 receives a force by the mutual action with a super-high frequency electromagnetic wave 2 propagating in the waveguide 1, and slightly snakes in the advancing direction, whereby an emitted light 5 is generated in the advancing direction. In this constitution, to change the wavelength of the emitted light 5, the input power of the super-high frequency electromagnetic wave 2 may be changed, or the frequency of the super-high frequency electromagnetic wave 2 may be changed, but to provide a greater effect, the wavelength variable ratio is increased by changing the frequency of the electromagnetic wave 2. The change of the frequency of the electromagnetic wave 2 is conducted, for example, by changing the current of the electromagnetic wave. The deflecting magnet 3 forms a changing means in this constitution.

Title: Thread tension guide of besting sewing machine
Inventor: SENDA YUTAKA
IPC: D05B47/04
Filed: 1990-05-21
Abstract: PURPOSE:To expand a cloth feeding period, while ensuring good stitch balance of basting by providing a resistance changeover mechanism in a thread tension guide such that the rotational resistance of a thread guide rotary body is changed over synchronously with an upper shaft through a cam mounted on said shaft and a rod in sliding contact with said cam. CONSTITUTION:In a thread tension guide of a basting sewing machine M, when an upper shaft 7 rotates during the sewing, a cam 29 of a resistance changeover mechanism 20 rotates, the rotational resistance of a thread guide rotary body 23 of a rotary type thread tension guide 14 is changed over synchronously with the shaft 7 through a rod 31. Within a period of time from a predetermined timing between the highest position of a needlebar 5 and that of a balance 11 to the timing when a sewing needle 6 is sticked into a fabric, the rotational resistance of the guide 14 becomes small enough to allow the feeding of the fabric and hence the fabric can be fed during this period. Furthermore, since a small resistance is imparted to a needle thread 12 in this surface, a small tension by the balance 11 is surely and property effected, wherein loosening of the needle thread does not practically occur, so that the thread does not slip out of a thread path.

Abstract: PROBLEM TO BE SOLVED: To reduce a sense of incongruity due to a difference between a real background noise and a pseudo background noise generated in soundless by synthesizing a decoded voice signal with the pseudo background noise from a pseudo background noise generation means. SOLUTION: A coded data receiving part 21 receives the coded data from a transmission line to send out it to a voice decoding part 22, and judges it as in-sound while the coded data are received, and judges it as in-soundless while the coded data aren't received. The voice decoding part 22 decodes/ outputs an original voice signal from the coded data while the coded data are received, and a voice power calculation part 24 calculates/outputs power of a decoded voice, and a volume adjustment part 25 performs volume adjustment so that the volume of the pseudo background noise from a pseudo background noise generation part 26 becomes the fixed ratio of the decoded voice, and the decoded voice is synthesized with the volume adjusted pseudo background noise by a synthetic part 23 to be outputted as the voice signal.  Thus, the pseudo background noise is loaded always at the fixed ratio according to the volume of a transmission side voice.
