Title: Tilt angle sensor
Inventor: KONOIKE TAKEHIRO
IPC: G01C9/06
Filed: 1991-07-29
Abstract: PURPOSE:To obtain a tilt angle sensor which is simple in structure, convenient to mass produce and low in manufacturing cost and which can always measure the tilt angle speedily with good accuracy irrespective of the size of the tilt angle. CONSTITUTION:A magnetic sphere 2 is movably sealed in an arced guide cylinder 1. A coil 3 is wound in the periphery of the guide cylinder 1 with rough and dense pitches. When the guide cylinder 1 is inclined in the outer peripheral direction, the magnetic sphere 2 moves inside the guide cylinder 1, generating the change of the positional relationship between the sphere and the coil 3. As a result, the magnetic resistance of the coil 3 is changed. Therefore, as the change of the magnetic resistance is detected, the tilt angle of the guide cylinder 1 can be measured. The inclination of a machine, a vehicle or the like having this tilt angle sensor incorporated therein can be hence detected.

IPC: H04B10/079
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a system which is the optical output cutoff system cutting- off output light for securing safety when disconnection, etc., arises in an optical cable and also the system suitable for long distance optical transmission with a repeater station. SOLUTION: It is detected that the optical signal from an opposite station is disconnected owing to the disconnection of the optical cable, etc., by a monitor control circuit 18. When input disconnection is detected, the optical signal obtained by executing the wave length multiplexing of an alarm optical signal 20 with prescribed wave length to a main signal by a wave length multiplexing coupler is returned to the opposite station where the input is disconnected. The opposite station picks-up the alarm optical signal 20 by wave length separation and the optical output of the alarm optical signal of an optical amplifier 16(17) towards the transmission station is cut-off. Since the alarm is reported by wave length multiplexing, the main signal is not required to be operated and the system is suitable for cutting-off the optical output in the repeater station.

Abstract: PURPOSE:To measure a liquid level accurately even if the outside wall of a liquid  storage means has a high temperature, by arranging a transmitter and a receiver so  that they are not brought into contact with each other. CONSTITUTION:A coil 2'' is excited by an external circuit preliminarily to generate  magnetic fields B1 and B2 in an outside wall 9'. When a strong high frequency pulse  current is flowed to a driver coil 5 by a current generating mechanism 7, the electric charge is migrated in speeds V1 and V2 in the outside wall 9' to induce an eddy current. In this case, the eddy current receives Lorentz forces F1 and F2 in the direction  orthogonal to magnetic fields B1 and B2 as shown in figure by solid lines in a short  time, and the outside wall 9' is displaced in the direction of forces F1 and F2, and  ultrasonic waves are generated in the direction of an arrow A and advance in a direction C in a tank 9 and are reflected partially by a liquid surface 10' of a liquid 10 and  advance in an opposite direction C' and strike the outside wall 9', and the eddy current induced in the outside wall 9' is detected by a detecting coil 6. A signal processing circuit 11 receives signals of the current generating mechanism 7 and an ultrasonic  wave generating mechanism 8 to operate a time spent from the generation of ultrasonic waves to the detection of them, and the liquid level of the liquid 10 is calculated  on the basis of this time.
