Title: Three-dimensional shape measuring apparatus
Inventor: KASEZAWA TADASHI
IPC: G01C3/06
Filed: 1991-05-22
Abstract: PURPOSE:To enable a three-dimensional shape with a single lens and simple signal process to be measured without using parallax between both lenses by changing a forcal length to an object in the photography by a camera device and using high region frequency component energy of an output signal and the focal length. CONSTITUTION:A camera device 1 photographs several-scores of images of frames by changing the focal length to a photographic object at every frame through a focal length adjusting circuit 2. The photographed signal is inputted to a high region frequency component energy detecting circuit 3 so that the high region frequency component energy divided locally or into small regions in each frame is detected. In the camera device 1 using a lens, since the most high region frequency component energy is detected in the state of matching forcusing distance, the focal length of the frame having the most high region frequency component energy detected is to represent a distance to the object in the small region.

Title: Bit synchronization system
Inventor: WATANABE AKIRA
IPC: H04L7/00
Filed: 1989-05-12
Abstract: PURPOSE:To shorten the time from the reception start till the bit synchronization by differentiating a transmission side clock in the process of synchronization from a reference clock for synchronization at a receiving side and decreasing the permissible range in an opposite phase where dphi/dt=0 takes place. CONSTITUTION:The relation of f1not equal to f2=f2 exists among the modulation speed (transmission clock f1 bps) of a transmission side preamble signal 1, the modulation speed (transmission clock f2 bps) of a data 2 and a receiving side synchronizing reference clock f3 bps and the relation of f1<f3 exists. Thus, the change in phi from the start of reception is rapidly decreased. Simultaneously, the deviation of a phase difference from phi=0 or the like takes place at the synchronization since the relation of f2=f2 exists in the data 2 after the bit synchronization in the preamble signal 1, the above-mentioned problem is avoided.

Title: Method and apparatus for measuring current and life diagnosing apparatus for breaking part of switch gear
Inventor: YAMADA HIROSHI
IPC: G01R19/00
Filed: 1990-05-07
Abstract: PURPOSE:To forecast and diagnose residual life of a breaking part by detecting a peak value of a needle-like waveform developing at a secondary output of a current transformer circuit (CT) to estimate a current value from a peak value based on a correlative relationship between the peak value and a main circuit current value. CONSTITUTION:When a large current flows to the primary side of a CT 2 to saturate it, a secondary output waveform presents a needle-like wave according to a degree of the saturation. The needle-like wave is detected and a peak value is held. After the value is converted into a digital value with an A/D converter 10, the current breaking current is calculated by referring to a peak value-current value conversion table calculated from a CT characteristic calculated beforehand. To secure the detection of the needle-like wave, a signal input circuit from an auxiliary CT 3 is provided with a high pass filter 8 having a specified characteristic. This enables the identification of a fundamental wave and the needle-like wave to make clear a correlative relationship between the level of a primary current and the peak value thereby achieving accurate estimation of the primary current.
