Inventor: HII UONGU
IPC: H03K5/1536
Filed: 1988-10-14
Abstract: PURPOSE: To make the system to highly immune to noise by respectively slicing a signal by a threshold level higher than a reference and a threshold level lower than the reference, detecting an adjacent pulse having reverse polarity, determining the existence of a bipolar pattern, and discriminating the center of the patten. CONSTITUTION: An amplifier 24 forms an inversional adding amplifier for generating an output for an equalizer and its output signal is applied to a group of input slicers and a level converter. The received signal is respectively sliced by the 1st threshold level exceeding the reference to obtain a positive polarity pulse and the 2nd threshold level lower than the reference to obtain a negative polarity pulse. The existence of a bipolar pattern is determined by detecting an adjacent pulse of a reverse polarity. Then the center of the bipolar pattern is discriminated and used for constructing retrieved timing information. Consequently performance more efficient than a highly accurate timing extractor to be influenced by noise can be provided.

Inventor: FUKUNAGA FUMIAKI
IPC: G06T7/00
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To achieve a part inspection for checking, for example, the type, shape, and appearance of parts as well as a wrong or missing part by photographing an externally mounted engine part in a specific direction and performing the image processing of the picked-up image screen. SOLUTION: A CCD camera 2 picks up the image of an externally mounted part (for example, a hose) of an engine 5 in a specific direction, for example, from above and the side. An image processing device 3 divides an image pick-up screen vertically and horizontally into a plurality of small regions and performs gray image processing of the inside of the small region, thus measuring the brightness distribution within each region. Then, the presence or absence of the externally mounted part and the approximate shape can be detected. Then, the amount of change of the brightness distribution of each small region is detected for every small region.  A personal computer 4 (incorporating a Fuzzy logic element) is used to compared detection data with reference data (acceptable article image pick-up screen), judge the agreement of the change amount with the reference data for every small region by the fuzzy inference, and inspect the wrong or missing externally mounted engine part according to the judgment over the entire small region.

Abstract: PROBLEM TO BE SOLVED: To continuously and accurately detect the mutual relative position between a guidance position mark and a traveling object and its traveling direction by performing an integrated operation of signals of a sensor heads which are assembled from plural position detecting sensors that are the same type of a function. SOLUTION: Four position detecting coils 16a to 16d are arranged on axes which are orthogonally crossed. When detection values of the coils 16a to 16d are made as VA to VD, the center Om of a circular mark plate 61 (position mark plate 11) is on a circular arc with the radius of displacement distance rA which corresponds to a detection value VA from the center A of the coil 16a, and similarly, on a circular arc with the radius of displacement distance rB which corresponds to a detection value VB from the center B of the coil 16b. Therefore, the center Om is either of these two intersected points of the circular arcs (Xm , Ym ) and (X'm , Y'm ). Furthermore, a circular arc with the radius rC from the detection value Vc of the coil 16c, and the coordinates (Xm , Ym ) of the center Om can be identified.

IPC: G01P21/00
Filed: 1987-10-16
Abstract: PURPOSE:To certainly detect acceleration, by distorting a piezoelectric element by the relative displacement of a vibrator to a case when acceleration is generated in moving body. CONSTITUTION:The case 1 of a piezoelectric type acceleration sensor 5 is fixed to a car body and the vibrator 2 of the sensor 5 is earthed through the case 1 and the car body. When a car begins to run, acceleration is generated in the car and the vibrator 2 is relatively displaced with respect to the case 1 in proportion to said acceleration. The strain proportional to said relative displacement is generated in a piezoelectric element 3 by the relative displacement of the vibrator 2 and the element 3 generates voltage having the magnitude proportional to strain quantity. Said voltage is outputted from the first and third electrodes 4a, 4c. That is, the electrodes 4a, 4c constitute the output terminals of the sensor 5. In this case, since the electrodes 4a, 4c are arranged so as to be opposed to each other, the outputs thereof are averaged. Therefore, the voltage signals outputted from the electrodes 4a, 4c become highly accurate ones and acceleration can be certainly detected.
