Patent JP-H02307021-A (JP)
Title: Liquid level measuring instrument
Inventor: OTA HARUO
IPC: G01F23/02
Filed: 1989-05-22
Abstract: PURPOSE:To allow the easy viewing of a liquid level and to decrease the generation of errors in measurement by measuring the liquid level in a liquid container by the gas-liquid boundary level in a gas-liquid piping. CONSTITUTION:A label 20 is stuck as a back ground to the range of nearly half the outer peripheral surface of a display tube 17 and is drawn with black diagonal stripe patterns on a yellow ground. The stripe patterns of the label 20 are visible uniformly as shown in (a) when there is no raw material in the display tube 17. The stripe patterns of the label 20 are visible in such a manner that the patterns on the lower side (raw material side) are larger than the patterns on the upper side (gas side) with the liquid level shown by an alternate long and short dash line as a boundary, as shown in (b), when there is the raw material in the display tube 17. The position of the boundary itself is explicit and more easily visible by the difference in the sizes of these patterns. Such difference arises from the lens effect by the raw material.

Title: Fluorescent display device
Inventor: KOMATSU HIROSHI
IPC: H05B44/00
Filed: 1989-05-23
Abstract: PURPOSE:To obtain excellent picture with high resolution and no crosstalk by providing picture element electrodes, switching element which are connected to the picture element electrodes, respectively, and matrix signal lines which drive the switching elements. CONSTITUTION:The writing work to picture elements is finished after a selection time, which is then made into a non-selection time. During the non-selection time, the potential of a gate electrode 305 is lower than that of a source electrode 306 or a drain electrode 307, and the channel of a TFT is turned into non-conductivity. A grid electrode 302 is, however, kept to be a constant potential by a parasitic capacity of electric charge even during the non-selection time, allowing electrons to flow through an anode electrode 303 continuously and light emission to be continued. This light emission is held till new data is written, if a parasitic capacity of electric charge is not discharged. During the non-selection time, the data signals for other picture elements are led into the electrode 306, but the TFT is turned into non-conductivity and so the potential of the electrode 302 does not interfer with the potential of the electrode 306, without occurrence of crosstalk.

Title: Apparatus for guiding passage of plate to coating roll
Inventor: TAKANO KIYOSHI
IPC: B05C1/02
Filed: 1986-06-03
Abstract: PURPOSE:To prevent the protrusion of a viscoelastic resin to the leading end surface of a metal plate, by transversely mounting a plate body inclined so as to contact the leading end part of the metal plate with a backup roll at first in front of the metal plate insert side of a coating roll. CONSTITUTION:The leading end part of a metal plate 3 at the time of supply to a coating roll 1 through a feed roll is contacted with the inclined surface 6a of a plate body 6 immediately before the supply of the metal plate 3 to said roll 1 and allowed to further advance to be guided forwardly while slid with the surface 6a. Because of this, the up-and-down movement of the metal plate 3 is suppressed. Since the leading end part of the metal plate 3 is contacted with the backup roll 2 at first, the metal plate 3 is perfectly prevented from up-and-down movement and receives rolling action between the leading end part of the plate body 6 and the backup roll 2 and, therefore, a viscoelastic resin 4 is applied to the metal plate in such a state that warpage or bending is corrected.

IPC: E21D11/38
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To secure a highly impervious property and allow a relative displacement by providing a water-tight fitting part to drift at one end of a beltlike elastic member and providing a water-tight fitting part with a shaft at the other end and shaping both water-tight fitting members to have a semicircular form or a bellows-shaped form. SOLUTION: The connection part of a drift 5 and a shaft 6 is previously constructed with a considerable gap 7 to accept a diastrophism. A flexible joint 1 is fitted to a water-tight fitting part 3 between the opening cross sectional face of a drift 5 and the inside wall face of a shaft 6 to prevent water leakage. A distance L1 between both water-tight fitting parts 3 is made longer than a straight distance L2 between the fitting part of the drift 5 and the fitting part of the shaft 6. That is, the flexible joint 1 is formed semicircular or the like to absorb a relative displacement caused by a diastrophism by displacement of the flexible joint 1 and secure the impervious property. Even number of fiber reinforced layers are laid alternately at every layer in a biased direction in the beltlike elastic member.  In this way, a sufficient strength can be secured and the joint becomes pliable.
