Title: Fault detecting apparatus of inner pressure in tube
Inventor: IWATA TOSHIO
IPC: G01L23/10
Filed: 1988-03-18
Abstract: PURPOSE:To make it possible to detect the fault of a sensor with a simple constitution, by providing an operation amplifier, a zero-crossing detector and a fault detecting circuit. CONSTITUTION:Electric charge Q is outputted in correspondence with the inner pressure in a tube shown in Figure (a) based on the output of a piezoelectric inner pressure sensor 1 in the tube. Then a current expressed in -dQ/dt is outputted from an amplifier 2 to a resistor 3 based on the feedback control of the operation amplifier 2. An output voltage V1 of the amplifier becomes V1=-R1.(dQ/dt), where R1 is the resistance value of the resistor 3, owing to the voltage drop across the resistor 3. An output waveform shown in Figure (b) is obtained based on said voltage value. The zero crossing point of the output waveform is detected with a zero crossing detector 5. When the sensor 1 is operating normally, the output waveform in Figure (a) is obtained, and a detected pulse in Figure (c) is obtained from the detector 5. Thus, a fault detecting circuit 6 judges the sensor as normal. When the sensor 1 is defective, the output waveform in Figure 1 cannot be obtained from the sensor 1. The output waveform form the amplifier 2 does not cross the zero level. The pulse in Figure (c) is not outputted from the detector 5. Therefore, the circuit 6 judges the sensor as defective.

Title: Wave power energy converting device
Inventor: ICHIKAWA AKIRA
IPC: F03B13/24
Filed: 1982-04-14
Abstract: PURPOSE:To prevent breakage of a main chamber due to the excessive increase of an air pressure in the main chamber and improve the safety thereof by a method wherein a sub-chamber, capable of absorbing a part of the wave power energy only when abnormally large waves are coming, is provided at the wave receiving side of the main chamber. CONSTITUTION:When the device is attacked by the abnormally large waves, the level of water in the sub chamber 16 repeats up-and-down motions and air in the space 18 of the sub chamber repeats compression and expansion thereby generating an airstream in the direction of an arrow sign E at the opening 19 thereof. In this process, a part of the wave power energy of the abnormally large waves attacking the device is consumed and, further, a part of the same energy is also consumed by a wave eliminating protuberance 17. Accordingly, the wave power energy projected into the main chamber 2 may be weakened considerably, the maximum level location 14 in the main chamber 2 will never become so abnormally high, and the breakage or the like due to the excessive increase of the air pressure in the main chamber 2 may be prevented.
