Title: Detection of connecting point of optical fiber
Inventor: AJIEI KEI RUSURA
IPC: G01M11/02
Filed: 1990-05-02
Abstract: PURPOSE:To make it possible to ensure the detection of a signal caused from the connecting points of optical fibers by adjusting the weighting coefficient of a linear predicting filter at the optimum value in response to a returning signal, removing the exponentially reducing component from the returning signal with said filter, and further removing noise component with correlation filter. CONSTITUTION:Optical pulses are supplied into an optical fiber. The connecting point of optical fibers is detected in correspondence with a signal returned from the optical fiber. Namely, at first, a weighting coefficient for a linear predicting filter is set based on a part of the returning signal. Then, an error a signal obtained by removing the exponentially reducing component from the returning signal with the linear predicting filter is generated. Furthermore, a low-noise error signal obtained by decreasing the noise component from said error signal using a correlation filter is generated. The low-noise signal is compared with a threshold value level. The connecting point of the optical fibers is detected based on the result of the comparison.

Abstract: PROBLEM TO BE SOLVED: To provide a motor-operated reel for fishing, having an overheat- preventing apparatus superior in responsibility and return response against overheat of a motor or power semiconductor constituting a motor drive unit. SOLUTION: To judge whether a motor or power MOSFET 10 which is a power semiconductor sealed inside a case constituting a motor drive unit is in an overheated state, the case temperature of the motor case or power MOSFET 19 is detected by a PPTC(polymer positive-temperature-coefficient thermistor) 18. When the motor or power MOSFET is in the overheated state, the temperature of the PPTC 18 also rises, and the resistance value of the PPTC 18 increases suddenly before and after a transition temperature. As a result of this, a control output signal from a CPU 7a is interrupted, and power supply to a spool winding-up motor is interrupted. As a PPTC 18, one having a transition temperature lower than the burning temperature of the motor or power MOSFET 19 is selected.

Title: Liquid level indicator utilizing optical fiber
Inventor: ISHIDA SADAO
IPC: G01F23/28
Filed: 1987-05-15
Abstract: PURPOSE:To obtain an accurate, inexpensive device by bundling optical fibers which have tips cut at a >=45 deg. angle to the fiber axes and other ends coupled with a light collector through a condenser lens so that the tips are at a specific distance. CONSTITUTION:The tip of an optical fiber 25 is cut at a >=45 deg. angle theta to its fiber axis and the cut surface 25D is polished into a specular surface; and the other end is connected to the light collector 22 through the lens 24 and a neck 23. Plural optical optical fibers 25 are put together into a bundle 14 so that their tips are at the specific distance. This liquid level indicator is fitted to a container which contains liquid such as liquefied petroleum gas. When the tip of the optical fiber 25 contacts the gas, light which is incident from the light collector 24 is reflected totally by the cut surface 25D and travels backward in the optical fiber 25, and a surface 22A illuminates brightly. When the surface 25D contacts liquid, on the other hand, the light is hardly reflected, so the surface 22A is dark. The height of the liquid surface is therefore detected from the steps of the tips of the arranged optical fibers.
