Title: Cablelike acid liquid detecting sensor
Inventor: KOJIMA KAZUYUKI
IPC: G01N27/06
Filed: 1989-07-14
Abstract: PURPOSE:To surely detect the arrival of an acid liquid by using a wire body consisting of an insulating material as a core, forming a metallic thin film dissolved in an acid in the longitudinal direction of the outside surface of the wire body, and providing insulation coating having a liquid passing property on the outside of the thin film. CONSTITUTION:On the outside surface of a round wire 1 formed by plastic, galvanization 2 is performed continuously in the longitudinal direction. Also, a solid wire 3 in which a conductor 3A is placed in the center and insulator coating 3B is performed to the periphery is placed in parallel to the round wire 1, and a twisted wire is constituted of the round wire 1 and the solid wire 3. Also, the periphery of the twisted wire is covered with a blade 4 made of plastic having a liquid passing property. In the case of using such a sensor, the conductor 3A and the galvanized 2 part are connected in a short state in one terminal part, and the other terminal part is connected to a detector. In this state, when an acid liquid reaches the sensor, the acid liquid passes through the blade 4 and intrudes into the inside of the sensor, dissolves the galvanization 2, and a conducting state by the galvanization 2 is cut off. Therefore, by observing this variation by the detector, the arrival of an acid liquid can be detected.

Title: Method for controlling transmission level value
Inventor: SAYAMA KATSUMI
IPC: H04L29/06
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To reduce attenuation and distortion of a signal due to unbalance between a transmission level value and a reception level value to the utmost by comparing an object reception level value set in advance to a transmitter with a reception level value of a receiver and revising the transmission level value of the transmitter as a result of the comparison. SOLUTION: A transmitter transmits a CNG signal to an opposite device in the case of communication with the opposite device (S201). In the case of receiving an NSF signal from the opposite device after that (S202/YES), the transmitter confirms whether or not the NSF signal has reception value information of a receiver (S206). When the NSF signal includes the reception level value information (S206/YES), the transmitter selects a transmission level (S207) to correct the unbalance between the transmission level value and the reception level value. Then the transmitter conducts transmission (S208). The transmitter change the transmission level value on the basis of the reception level value of the receiver transmitted from the receiver in this way, excellent communication can be conducted.
