Title: Liquid crystal panel and liquid crystal display device therewith
IPC: G02F1/1333
Filed: 1992-04-03
Abstract: PURPOSE:To provide a liquid crystal display device which features high contrast and low power consumption. CONSTITUTION:A micro lens 18 is formed on a glass substrate 16 so as to correspond to a picture element by using a high polymer dispersion liquid crystal for the liquid crystal of a liquid crystal panel. The glass substrate 16 is made by sticking an array substrate 12 together with an infrared hardening type acrylic adhesive layer 17. Upon the liquid crystal panel, light is incident from a facing electrode substrate side, and is modulated with a high polymer dispersion liquid crystal layer 15 based upon a video signal applied to each picture element electrode 14. After light passing through a color filter 13 for R color is modulated, it is refracted with the micro lens 18 to make outgoing radiation. Light from an R picture element is refracted with the micro lens 18 to wholly show the same dispersion characteristics as light passing through a B and a G picture element. Therefore, a high contrast display may be performed as a whole.

IPC: G01F1/84
Filed: 1989-03-31
Abstract: PURPOSE:To prevent the collapse of natural frequency and to make it possible to measure a flow rate stably by extending the straight tube parts of a pair of sensor tubes in the horizontal direction, and arranging bent parts and connecting parts symmetrically with respect to a vertical plane in the lateral direction. CONSTITUTION:Straight tube parts 22a and 22b and 23a and 23b of a pair of sensor tubes 22 and 23 are made to extend in the horizontal direction. Bent parts 22c and 22d and a connecting part 22e and bent parts 23c and 23d and a connecting part 23e are arranged symmetrically with respect to a vertical plane. When a flow rate is measured, a specified fluid is made to flow and vibrators 33 and 34 are vibrated. Then, the sensor tubes 22 and 23 are vibrated at a natural frequency determined by the constants of springs and the flow rate at this time. Even if bubbles are mixed in the fluid at this time, the bubbles are easy to stagnate at the straight tube parts. The stagnating positions are the approximately same positions in both tubes 22 and 23. Therefore, the natural frequency is not disrupted. The flow rates can be measured stably with pickups 29 and 30.

Abstract: PURPOSE:To make a clamper for assembled parts adaptable to a body setting position, by positioning the assembled parts with an engaging member in advance at the time of locking a clamper clamping device with a movable member, while positioning the assembled parts and a body both with a guide member. CONSTITUTION:With a completion signal of engagement between a strut P and an engaging member 96, a lock state in a floating value setting mechanism 14 is released free, and thereby a movable plate 12 is floatingly supported by a floating mechanism 19 in a surface direction whereby the strut P is also floatingly supported by a grip hand. And, in proportion as a robot makes a nut clamping device go down, a guide member 97 also goes down, and a guide taper part 42a comes into contact with a flange 3a at an edge of a positioning hole 3 for a car body, and when the member 97 futher goes down, since it is energized with a spring 54, the taper part 42a comes into slidingly contact with the flange 3a and fitted in the hole 3 as self-centripetally moving, thus the robot stops. In consequence, correlations among the car body, the strut P and the nut clamping device are determined so that a lock member 13 is set in motion of its own.

Abstract: PROBLEM TO BE SOLVED: To resume printing from a place where printing failure is caused even in the case where printing failure is caused during printing in an ink jet printer. SOLUTION: When printing is started on the basis of a printing command, jet failure is also detected according to the printing command (S5, S6).
