Title: Hazardous smoke inhibiting device for ship
Inventor: SUGIOKA TOSHIYUKI
IPC: B63H21/34
Filed: 1984-09-27
Abstract: PURPOSE:To inhibit hazardous smoke by a method wherein a blower is operated in response to a condition in which hazardous smoke is generated. CONSTITUTION:An air speed meter and an air direction meter are mounted on a bridge and a relative air speed and a relative air direction are outputted to a control device 3. To the control device 3 is further inputted a smoke discharging speed. This discharging speed can be got from an output of the engine or a suitable sensor is arranged in a chimney to detect a smoke discharging speed. In the control device 3, at first a relative smoke discharging speed = smoke discharging speed/relative air speed is calculated and if the calculated value is higher than a desired value, a blower stop instruction is outputted. If the calculated value is less than the desired value, it is judged whether a relative air direction is in a range of desired value or not and if it is out of the range, the stop instruction is outputted and if it is in the range, an operation instruction is outputted. With the foregoing, when the blower 1 is started to blow in reference to the output from the control device, the smoke from the chimney 50 is blown off upwardly, so that the smoke may not be taken into the turbulence flow area and no hazardous condition of smoke may exist.

Title: Ultrasonic flaw detecting method for welded shape steel
Inventor: FUJISAWA KAZUO
IPC: G01N29/04
Filed: 1981-12-11
Abstract: PURPOSE:To detect a flaw in a weld zone with high precision by oscillating an ultrasonic wave beam converged through a medium to left and right about a center weld line, and successively monitoring echo from a position corresponding to the bottom surface thickness of a flange member while transporting shape steel whose flaw is to be detected forward and backward. CONSTITUTION:An ultrasonic wave probe 1 uses a convergence type probe and a thin beam 1' is made incident to a flange member (a) at right angles from the top surface through a medium 3 such as water. When an oscillator diameter is 6mm., a flaw detection frequency is 10MHz, and focal length is 15mm., the incidence of a thin beam with an about 0.5mm. diameter is possible. Then, the oscillator while oscillating at, for example, 20-50Hz oscillation frequency to left and right (at right angles to the transportation direction of H shape steel, i.e. horizontally in figure) moves welded shape steel forth and back to monitor echo from the bottom surface of the flange member for a faulty part. This method allows flaw detection within the amplitude range of the probe even when a weld line deviates to left and right, so high-precision inspection is performed.

Title: Voltage controlled oscillator
Inventor: KOIZUMI HARUO
IPC: H03B5/12
Filed: 1992-07-28
Abstract: PURPOSE:To obtain an always stable oscillating frequency by devising the oscillator such that an inductance not adjusted to set the oscillating frequency to be within a desired frequency variable range to a main coil being a divided component of a coil and the sub coil is formed so that its inductance is adjustable. CONSTITUTION:A coil is divided into a main coil L1 and a sub coil L2 connected in series. The main coil L1 whose inductance is not made adjustable to set the oscillating frequency to be within a desired frequency range is provided with capacitors C1-C5. The inductance of the sub coil L2 is made adjustable and the inductance is adjusted so that a DC inverse voltage applied to a varactor diode VD is almost a center voltage of the applied voltage to the oscillator in order to obtain a center frequency within the desired oscillating frequency range through the variable adjustment of the small inductance. The adjustment is implemented quickly and simply without dispersion because the fine adjustment of the small inductance of the sub coil L2 is only required. Furthermore, since the inductance of the main coil L1 requires no adjustment and is not changed, the effect of the main coil onto the oscillating frequency is almost less and the always stable oscillating frequency is obtained.
