Title: Detection of pinhole on pipe body
Inventor: SHIMOMURA TAMAMI
IPC: G01M3/24
Filed: 1990-11-19
Abstract: PURPOSE:To easily detect the existence and position of a pinhole by installing sound wave detecting sensors at two places on a tubular body, detecting the sound which is formed by the leak of the pressurized gas from the pinhole on a pipe, and comparing the wave shape of the sound wave. CONSTITUTION:When a pin-hole 11 exists on a tubular body 1, pressurized gas leaks from inside, and leak noise reaches both the edges of the pipe 1, and detected by the sound wave detection sensors 21 and 22, and the result is displayed on the display devices 31 and 32, and the sound wave shape is compared. If the wave height values of the displayed wave shapes of the sensors 31 and 32 are equal, the pinhole 11 exists at the intermediate point of the positions of the sensors 21 and 22, and if the wave height value on the display device 31 side is sufficiently large, it is judged that the pinhole 11 exists in the vicinity of the sensor 21. The installation division of the sensors 21 and 22 is represented in ratio form from the ratio of the attenuation degree of the wave form, and the position of the pinhole can be calculated.

Title: Optical waveguide
Inventor: MITSUMA TAKASHI
IPC: G02B6/122
Filed: 1987-12-10
Abstract: PURPOSE:To simplify the manufacturing method by constituting the title waveguide of a superlattice structure which has varied each layer thickness so that an equivalent refractive index distribution of two kinds of materials whose refractive indexes are different becomes equal to a refractive index inclination. CONSTITUTION:A refractive index distribution area is divided into N equal parts, refractive index decrease ratios (a), (b), (c)... corresponding to them are derived, and by this ratio, a refractive index n2 is placed, and a part between them is set as a refractive index n0. In this case, when an interval of thin layers of the refractive index n2 is narrower enough than wavelength of a waveguide light, a distribution shape of an electric field of a light beam which is brought to waveguide becomes almost the same as the case of an ideal refractive index distribution shape as shown in the figure A. In case of generating actually a micro-refractive index distribution as shown in the figure B, a superlattice structure which has laminated a thin layer 21 of a material of the refractive index n2 and a thin layer 22 of a material of the refractive index n0 at an interval as shown in the figure B is formed as shown in the figure C. In this case, as for the refractive index n2, a value of a material (n2>n1>n0) which is obtained easily, and by its layer thickness, the maximum value of an equivalent refractive index is aligned with n1. In such a way, the manufacturing method is simplified.

Filed: 1986-12-23
Abstract: PURPOSE:To decrease the leakage current and residual voltage and to prevent malfunction by providing a feedback circuit connected to a gate of a MOS.FET and connected in parallel with a current sensing element. CONSTITUTION:In applying power, a rush current is caused and a smoothing capacitor C1 is going to flow to a constant voltage circuit, but the rush is limited to a constant current by the current sensing element R11 and the feedback circuit TR4 and no rapid charging is applied to a smoothing capacitor. When a detection circuit 15 outputs a detection signal, since the anode voltage of a Zener diode ZD4 rises, a switching element 16 is triggered and conducted to drive a load. Since the feedback circuit TR4 keeps the gate voltage of the MOS.FET 14 to a threshold voltage or over, a constant current is supplied to a switching element 16 and the load is driven normally. In such a case, a voltage is supplied from the smoothing capacitor C1 to the detection circuit 15 and normal detection function is kept.
