Title: Liquid level controller
Inventor: KURUMAYA YOZO
IPC: G05D9/02
Filed: 1994-05-26
Abstract: PURPOSE:To simplify structure and to improve reliability by controlling high- pressure liquid without using any large float by providing a float for detecting the liquid surface level on the low liquid surface side and operating a ring mechanism corresponding to its vertical displacement. CONSTITUTION:When the water level of a paddy field rises, a float 4 rises and a first control link 50 is oscillated upward but when the water level of the paddy field reaches the peak water level, the first control link 50 kicks a lock plate 63 so that the engagement with lock is canceled. At the same time, a second control link 51 opens a first control valve 54 and closes a second control valve 56. Therefore, the supply of water to the paddy field is cut off. On the other hand, when the water level of the paddy field is lowered gradually from a water filling state, the float 4 falls down and when this float 4 reaches a standard water level, the first control link 50 is oscillated downward corresponding to the falling of the float 4. Then, the second control link 51 closes the first control valve 54 and opens the second control valve 56. Therefore, a water supply port 22 is opened and water is supplied to the paddy field.

Title: Forming mechanism for single-thread chain stitch seam
Inventor: OGAWARA AKIRA
IPC: D05B1/06
Filed: 1989-05-31
Abstract: PURPOSE:To surely extend needle thread loops under proper needle thread feed independent of the thickness of thread, by a method wherein a securing groove for the needle thread is formed at a thread-scuring part on a looper, and a thread holder is composed of a projecting member, and this projecting member is directly fitted on the under surface of a throat plate. CONSTITUTION:A projecting member 2 as a thread holder provided on the under surface of a throat plate 6 is located near the located point of a sewing needle N. On the other hand, although his projecting member is only projected at the under surface of the throat plate 6, it has a size enough for holding a needle thread loop. Since the thread holder is composed of the projecting member 2 like this, a distance H2 form the top of the throat plate 6, i.e. a workpiece, to the thread holder 2 can be made extremely small, and hence the amount of the needle thread fed for making the needle thread loop below the workpiece becomes a necessary and sufficient amount proper. In this way, sigle-tread chain-stitch seams with good tightness can be formed.
