摘要:
A sewing apparatus displays a stitch pattern and forcibly supplies a thread based on the displayed stitch pattern. The apparatus comprises a sewing mechanism, an automatic thread supply device, a key input unit, a memory, a selector and a display. The sewing mechanism has a sewing section which includes a needle and a looper driven in accordance with a rotation of a main shaft. The automatic thread supply device forcibly carries a needle thread and a looper thread to the sewing section. The key input unit sets lengths per stitch of the needle thread and the looper thread which are to be supplied by the automatic thread supply device to the sewing section. The memory stores a plurality of stitch patterns in correspondence with combinations of the lengths of the threads to be supplied per stitch. The selector selects one of the stitch patterns corresponding to the combination set by the key input unit. The display displays in graphics the stitch pattern selected by the selector.

An automatic thread supply device for a conventional overlocking sewing machine is disclosed. Each of a needle thread, an upper looper thread and a lower looper thread is supplied to a thread supply roller but the supply is stopped for an optimum period by a thread holder, whereby the supply length of each thread is adjusted. In forming a thread chain, the total supply length of the looper threads is not more than five times of the length of the needle thread, and the smallest length of the above threads is not more than half of the total length of the remaining threads. In this way, a highly expandable thread chain is formed having a good appearance.

A demultiplex unit demultiplexes the optical output of a Mach-Zehnder optical modulator and inputs the demultiplexed optical output to a wavelength detection unit. The wavelength detection unit detects the wavelength deviations in the ascending or descending part of the optical signal and inputs the wavelength deviations to a detection unit. The detection unit detects the sign and magnitude of chirping in the magnitude of wavelength deviation and inputs the sign and magnitude of chirping to a driving voltage control unit. The driving voltage control unit compares the detected sign and amount of chirping with the target sign and magnitude of chirping, and a driving voltage generation circuit provides the Mach-Zehnder optical modulator with a suitable driving voltage.

A signal processing apparatus sets a discrimination level most suitably, regardless of whether the apparatus is in the minimum receiving system or the maximum receiving system. The apparatus comprises a light receiving unit converting input signal light to an electric signal, and a level detecting unit for detecting a high level component and a low level component of the electric signal from the light receiving unit, along with peak levels on a high-side and a low-side of the electric signal.

In a mobile antenna, an electrically conductive antenna element has a first portion with one end and the other end extending therefrom. The one end of the first portion is arranged at least adjacent to any one of a first support portion, a second support portion, and a corner portion of a body of a vehicle. The one end of the first portion is electrically connected to a feeding point. The other end of the first portion is arranged along a surface of the window such that polarized surfaces formed by the antenna element are non-orthogonal to a polarized surface of each of a vertically polarized wave and a horizontally polarized wave in radio waves.
