Title: Optical output controlling circuit
Inventor: IMAMURA KEIICHI
IPC: H01S5/042
Filed: 1987-06-12
Abstract: PURPOSE:To facilitate coping with a burst signal by a method wherein the output of a regulating means is changed so as to make the level of a bias current lower than the threshold level of a light emitting device when no signal is inputted into a 2nd transistor. CONSTITUTION:In a no-signal state, an RTS (Request To Send) signal given to the positive phase sequence input of the gate lC3 of an ECL (Emitter Coupled Logic) is at a low level and hence the output of the gate IC3 is also at a low level and given to the positive phase sequence input of an operational amplifier IC2 constituting a reverse amplifying circuit. On the other hand, in the no-signal state, a semiconductor laser LD is in an extinguished state and hence a monitor current is not applied to a photodiode PD. Therefore, the output of the operational amplifier IC2 is fixed at a low level. Then, if the value of a resistor R9 is properly selected, a bias current in this state can be fixed at the value lower than the threshold current of the semiconductor laser LD so that the light emission of the semiconductor laser LD in the no-signal state can be avoided. With this constitution, a burst signal can be coped with.

Title: Artificial fishing bank
Inventor: KOBAYASHI SHOZO
IPC: A01K61/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a readily manufactured and assembled artificial fishing bank capable of easily gathering fish schools and excellent in durability. SOLUTION: This artificial fishing bank is obtained by laminating fish passage stages 3 having plural passages 2 arranged in one direction side by side and arranging the passages 2 in each fish passage stage 3 so as to cross in the vertical directions for one stage or each of the plural stages. Thereby, the manner of flowing seawater flowing through the interior of the passages 2 varies with each passage 2 different in direction and the fishing bank is responsive to the manner of flowing preferred by fishes. Since the lateral face and the top and bottom surfaces of each passage 2 are shielded, the fishes are capable of hiding themselves from fishes of enemy character and a turbulent flow unsuitable for the habit of the fishes is not produced. Thereby, the fishes readily gather to afford excellent fish gathering effects.  Connecting rods 8 having fixing means 9 at the ends thereof are passed through prescribed positions of each of the laminated fish passage stages 3 in the vertical directions so as integrate each fish passage stage 3 with the connecting rods 8. As a result, the assembling is readily carried out to make fish passage members 4 constituting each fish passage stage 3 of cast iron. Thereby, corrosion with seawater is reduced to provide the durability.
