Title: Automatic equalizer with beacon signal supressing function
Inventor: OTA TAKAHISA
IPC: H04B3/06
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To effectively suppress a beacon signal utilized to take symbol synchronization at a receiving side and to prevent an error of a code in a partial response system of a class 4. SOLUTION: A beacon cancel signal B is added to an output signal of a transversal filter 2 of an automatic equalizer by using an adding circuit 8. The beacon cancel signal B is an opposite phase signal of the beacon signal and the beacon signal is cancelled. Furthermore, a true value of the output signal of the adding circuit 8 is judged in a judging circuit 4. An equivalent residual error signal En is calculated by calculating a difference between the judged true value and the output signal of the adding circuit 8. The beacon cancel signal B is corrected based on the equivalent residual error signal En by a beacon canceller. As a result, the beacon signal is suppressed even when amplitude and phase of the beacon signal are fluctuated.

Title: Leakage oil sensor detection
Inventor: SATO MITSUHIRO
IPC: G01M3/04
Filed: 1989-05-19
Abstract: PURPOSE:To monitor existence of leakage oil with an ITV camera by a method wherein a white cloth tape applied with a black fine particle layer is wound around a cable connection part and a valve of oil tubing, etc. CONSTITUTION:When a small amount of oil leaks from a screw clamp part or the like of a valve 3, the oil is brought into contact with fine carbon particles 2 on the inner face of a cloth tape 5 to make its color change into black. This colored oil comes up to the surface of the cloth tape 1 through it by capillary action. Since the cloth tape 1 is white, oil leakage can be easily found by monitoring with an ITV camera. Even if oil leakage occurs underneath the valve 3, the oil comes upward by capillary action so that observation with the ITV camera is possible wherever the oil leakage occurs. Therefore leakage of small amount of oil can be easily and securely detected.

Abstract: PURPOSE:To continue with the normal driving of an engine as well as to make improvements in safety, by calculating a span of ignition timing on the basis of a period of the reference signal and keeping on doing the ignition control in the case where anything trouble occurs in a unit angle signal out of a crank angle sensor. CONSTITUTION:A control unit 6 counts the number of input times per unit time of a unit angle signal out of a crank angle sensor 3, detecting an engine speed N, and on the basis of this detection and a suction air flow rate Q out of an air flow meter 5, calculates the ignition timing conformed to an engine driving condition. And, at that point that the number of input times of the unit angle signal from time of inputting a reference signal is congruous with the ignition timing, ignition takes place. Parallaling this, it judges of whether there is anything trouble in output of the unit angle signal or not, and measures a period of reference signal input and the required time from after the reference signal input to the ignition timing in advance. And, when judging that something is wrong with the unit angle signal, it performs fail-safe control for ignition at that point that the required time elapses after the reference signal is inputted.
