Title: Automatic equalizer
Inventor: AKASHI FUMIO
IPC: H04L1/24
Filed: 1979-09-26
Abstract: PURPOSE:To widen sufficiently the acquisition range of automatic equalization by providing an error correcting method that makes use of the regularity of a bipolar code. CONSTITUTION:A received signal from terminal 1 is inputted to automatic equalizer 2 and an equalized output signal is discriminated by threshold detecting circuit 3, which outputs a discrimination signal, consisting of three levels corresponding to [1], [0] and [-1], to comparing-correcting circuit 4. Comparing-correcting circuit 4 detects and corrects an error of the discrimination signal by making use of the regularity of the bipolar code to output a corrected discrimination signal. Then, the corrected discrimination signal and equalized output signal are inputted to automatic-equalizer correcting circuit 5, which suppies a corrected variable gain to automatic equalizer 2. Consequently, no error gain adjustment is made even if a discrimination error is generated while the equalizer does not provide sufficient equalization, so that stable acquisition operation will be performed.

Title: Velocity sensor device
Inventor: KANO YOSHIO
IPC: G01P3/54
Filed: 1990-05-14
Abstract: PURPOSE:To continuously detect and output the velocity of moving object in non-contact, to reduce the accident damaging a band-shaped resistance body, and to attain an increase of durability by the fact that a specified electromotive force is generated between mutual electrodes in the orthogonally crossed direction to the moving direction of the moving object on the band-shaped resistance body when the mobile object is moved along the band-shaped resistance body. CONSTITUTION:The value of movement velocity of the moving object M can be continuously detected in non-contact and outputted. Since a movable yoke 2 is arranged at the position confronted with one side face of a fixing pedestal 1, the yoke 2 can be miniaturized and an entire face of another side of a resistance film 4 is fixed with a circuit board 3, and also since the entire face of another side of the board 3 is fixed on the pedestal 1, the exposed area of resistance film 4 is decreased. Consequently, the durability of resistance film 4 and board 3 can be increased, and also the resistance film 4 and output electrodes 5, 6 are effectively protected by an insulation film 7.

Title: Abnormality judging device and abnormality informing device for internal combustion engine
Inventor: FUJITA MASATO
IPC: F02D41/14
Filed: 1994-05-12
Abstract: PURPOSE:To precisely detect leakage of exhaust by using a learning value of an air-fuel ratio correction factor. CONSTITUTION:In learning values KGn, each of which is learned in every operation area on the basis of a deviation from a value 1.0 of an air-fuel ratio correction factor FAF, a learning value KG1 in an idling condition is the value for a high air-fuel ratio condition of an air-fuel mixture or more (S140) and leaning values KG3, KG4 learned by a running test in an acceleration area are not deviated from each other, it is determined that exhaust leakage occurs (S170, S180). If exhaust is leaked, new air is sucked by pulsation of a pressure in an exhaust system, so that air-fuel ratio control based on the output of an air-fuel ratio sensor is carried out in the same way as for an excess air condition of an air-fuel mixture. The deviation in the learning value KG by this control is generated greatly only in a low load area, so that existence of exhaust leakage can be precisely detected by determining a dimension of the learning value in the acceleration area additionally.
