IPC: G01N27/83
Filed: 1987-11-16
Abstract: PURPOSE:To accurately diagnose the inferiority of a main cable, by generating magnetic flux by allowing a current to flow to the main cable and detecting the same by a detection means consisting of a superconductive coil and a Hall element. CONSTITUTION:A power supply 21 is connected to the main cable 1 of an elevator to allow a current to flow to said cable 1 and magnetic flux phi is generated around the main cable 1. This magnetic flux is detected by the first coil 31 composed of a superconductive material and this detection current Is is guided to the second coil 32 similarly composed of a superconductive material. The second coil 32 is provided to a magnetism shield means 34 and the self- inductance thereof is made smaller than that of the first coil. The magnetic flux formed by the second coil 32 is allowed to pierce through a Hall element 33 and the output voltage of the Hall element 33 at that time is detected by a voltage detection means. When the main cable 1 is abraded and broken, the output voltage of the aforementioned voltage detection means changes and, therefore, by detecting this output change, the breaking state of the main cable 1 can be diagnosed.

Title: Cleaning device
Inventor: NOGUCHI TERUHIKO
IPC: G03G21/00
Filed: 1991-11-06
Abstract: PURPOSE:To prevent a blade from being deformed and to prolong the life of the blade. CONSTITUTION:When the non-image part of a photosensitive body 1 in the case of non-copying is cleaned, a rocking body 26 is drawn by actuating solenoid 28.

At this time, the blade 21 does not separate from the photosensitive body 1, and press-contacting force is weaker than that in the case of copying. Thus, the scattering of toner caused by the slipping through is prevented and the abrasion amount of a blade edge is decreased.

Title: Liquid crystal display device and driving method
Inventor: MATSUEDA YOJIRO
IPC: G09G3/36
Filed: 1992-10-28
Abstract: PURPOSE:To make a bright point defect difficult to be prominent, and to improve a picture quality by impressing an alternating voltage higher than the threshold value of a liquid crystal on a signal line or a scanning line in a vertical blanking period. CONSTITUTION:Each scanning line is successively selected in a vertical scanning period T1, and a voltage VH of a selection level is impressed on the scanning line only in one horizontal period T3. The alternating voltage higher than the threshold value of the liquid crystal is impressed on the signal line or the scanning line in a vertical blanking T2. At that time, the polarity of a picture signal is inverted in each one vertical scanning period, and when the cycle is set to the period T3 or the integer multiple of the period T3, in almost the half of the picture elements, the liquid crystal is always driven under the opposite polarity, so that a flicker and a crosstalk can be suppressed. Moreover, the voltage higher than a certain level can be always impressed, so that the black point defect can be made more difficult to be prominent compared with the white point defect, and the bright point defect can be made difficult to be prominent. Thus, the picture quality can be improved without increasing the cost.
