Title: Adjusting device of water level
Inventor: NOMURA HIDESHIGE
IPC: G05D9/12
Filed: 1982-10-14
Abstract: PURPOSE:To prevent the variation of a motor output due to the sudden change of water volume by controlling the opening of a guide vane at a previously fixed rate after turning on a prarllel braker. CONSTITUTION:When the parallel breaker is connected to a system, the value of a guide vane deviation signal is large and a contact KC is closed to the (b) side, so that the real opening eta of the guide vane 4 is gradually opened. If a rated water level Href is held at the time to when the water level H turns on a parallel breaker, an integrating time constant To decided by the water surface area of an adjusting pond 2 and a signal etaa decided by a water level adjusting ratio R are ''0'', and when the guide vane 4 is opened by an opening bias signal while keeping an inclination, the signal etaa is moved in the negative direction. Since a guide vane opening command signal obtained by adding a guide vane opening bias etaF to the signal etaa coincides with a real guide vane opening eta at a crossing point of time t1, (etaF+etaa-eta), a guide vane deviation signal, is turned to ''0'' and the titled device is turned to automatic water level adjusting operation.

Title: Article conveyor
Inventor: KOBAYASHI HIROAKI
IPC: B65G47/14
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To align articles in one line completely for conveyance with a simple structure by making a part of intermediate part in the article traveling direction of the bottom surface of a trough into a supercrest shape. SOLUTION: An article B which is brought into contact with the second side wall part 21B on the side of articles A, C and pressed against the bottom side of a trough 12 for conveyance is present (A). When the articles A, C reach the supercrest part 100 of the trough, the preceding article A is energized and accelerated by its gravity while it is going down on a downward gradient part at the outlet side of the supercrest part 100, and the subsequent article C is decelerated by the resistance of its gravity while it is going up on an upward gradient part at the inlet side of the supercrest part 100. By a speed difference between the acceleration of the article A and the deceleration of the article C, the article A and the article C are separated from each other to generate a void 104 between both of them (B).  If the length of the void 104 exceeds the length of the ateral article B, the article B moves laterally to the bottom middle of the trough 12 along the inclination of the second side wall part 21B (C). The article B enters the line of the articles A, C, D..., thus it is possible to make the articles arranged in parallel align in one line for conveyance.

As a result, the bottom part of the via hole is filled with a plating metal, a third conductor 25 is formed, and a fourth conductor 20 is formed on it. Consequently, when the wiring board is observed from its surface, a slight uneven part is detected on the surface of the fourth conductor 26 formed on the surface of the insulating layer 23.  The uneven part corresponds to a via hole part in the third conductor 25, and it can be aligned with a mask for patterning of a conductor layer.
