Title: Manufacture of metallic tube with spiral fin
Inventor: KURODA KOICHI
IPC: B21C37/20
Filed: 1988-09-02
Abstract: PURPOSE:To form the diameter of a rolling roll to several times of a metallic bar and to raise the production efficiency by using the rolling roll having plural pieces of annular grooves in the peripheral direction of the outside peripheral surface as the rolling roll, and a guide shoe having a groove on the side opposed to a solid metallic bar as the guide shoe. CONSTITUTION:A solid metallic bar B is heated to a prescribed temperature, and thereafter, fed to an inclined rolling mill 10, and bitten between rolling rolls 1, 2. The metallic bar B is held on a pass line X - X by the rolling rolls and guide shoes 8a, 8b and rotates around an axis center line and moves in the axis length direction. Subsequently, a plug 6 intrudes along its axis center line. Next, a spiral fin 5 is led successively into a groove 9 of the guide shoes 8a, 8b from an annular groove 4 of the rolling roll. Also, by the intrusion of the plug 6, a metal flows in the depth direction of the annular groove 4 from the inside surface of the metallic bar B. In such a way, by combining and using the rolling roll and the guide shoe, the diameter of the rolling roll can be formed to several times of the solid metallic bar or the metallic conduit, and by increasing a peripheral velocity of the rolling roll, the production efficiency can be raised.

Inventor: OKUMA KEIJI
IPC: G06T1/00
Filed: 1988-09-06
Abstract: PURPOSE:To detect the position of aquatic animals kept in a water tank even in the brightness of a room lamp, etc. by arranging plural symbols on the background of a fish of a subject opposed to an image pickup device, and detecting that the symbol on the background is hidden by a fish body, and determining the position of the fish by the position of the symbol hidden by the fish body.

Accordingly, it comes to be needless to extract the distinct binary picture of the fish body. Thus, the position of the fish can be determined without necessitating any special illuminating method. Besides, the room lamp capable of picking up the image of the symbol becomes enough, and the position of the fish can be detected by a method in which a threshold for obtaining the binary picture can be easily determined.

CONSTITUTION:A liquid to be measured flows in from an intake 1 for the fluid to be measured is sent by a feed pump 9 to the high-pressure side pressure receiving chamber 4, and part of it is sucked by the quantitative pump 3 to flow in the thin pipe 5 for measurement only by a constant amount and passes through the quantitative pump 3 from the low-pressure side pressure receiving chamber 6, so that it is discharged from an outlet 2 for the fluid to be measured. The remainder passes through the by-pass line 10 provided to the high-pressure side pressure receiving chamber 4 and is discharged from an outlet 11 for the fluid. At this time, the pressure of the high-pressure side pressure receiving chamber 4 and the pressure of the low-pressure side pressure receiving chamber 6 are guided to a differential pressure sensor 8 by a connecting pipe 7, so that the viscosity is found from the flow rate in the quantitative pump 3 and the differential pressure detected by the differential pressure sensor 8.

The servo control circuit 8 judges a focusing point from the output values of the wind comparator 7 and the comparator 9 and closes an AF-loop switch 4 and the focusing state is maintained. Thus, the AGC is always executed and the focus pull-in is executed without fail.

IPC: G05B19/19
Filed: 1985-10-07
Abstract: PURPOSE:To prevent the automatic operation stop state at an overload time by providing a control arithmetic circuit capable of switching between speed control and torque control. CONSTITUTION:A sped signal S of a driving motor 2 of an industrial robot body 1 is compared with a speed target value signal R1 of a set speed target value signal generating circuit 3, and a speed signal C1 is inputted to a control arithmetic circuit 4. A current signal T of the driving motor 2 is inputted to a torque detecting circuit and is compared with a signal R2 of a torque upper limit setting circuit 6, and a torque signal C2 is inputted to the arithmetic circuit 4. The arithmetic circuit 4 outputs a speed reduction command signal to a driving motor control circuit 7 if the signal C2 is negative; but the circuit 4 outputs a set speed target value coincidence command signal if it is positive. Thus, a control circuit 7 controls the motor by said command signal of the arithmetic circuit 4, and the operation speed is reduced within the capability value of the robot when a torque larger than the value for normal operation of the robot is required.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a distributed feedback semiconductor laser in which the linearity of an optical output is not disturbed by returned light by a method wherein only a clad layer is formed in a region in a specific range from a front edge and a dielectric film whose reflectance is in a specific range is formed at the front edge. SOLUTION: A region in which only a clad layer without an active layer exists is formed in a region of 10 to 50μm from a front edge which radiates light, and a dielectric film at a reflectance of 40 to 60% is applied to the front edge. That is to say, a front-edge coating film 20 at a reflectance of 40 to 60% is executed to the side of a window part 11, and a rear-edge coating film 21 at a reflectance of 60% or higher is formed. Thereby, light which goes out to the side of the window part 11 from the waveguide of an element is passed through the front-edge coating film 20, 40 to 60% is radiated to the outside, and 39% becomes a non-waveguide mode inside the element due to a window structure. Consequently, a reflectance as viewed from the inside becomes 1%. On the other hand, 40 to 60% is reflected by the front-edge coating film 20 with reference to a laser beam from the outside.
