Abstract: There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the piezoelectric actuator is at first given a voltage of inverse polarity, for generating a displacement in an opposite direction, and then given a voltage of forward polarity, for generating a displacement in the normal functioning direction, thereby actuating the mechanical system. Displacement and acceleration become larger, as the displacement of the actuator takes place from a position in the inverse direction. In another aspect, the electrical insulation state of the piezoelectric actuator is detected, and, if deteriorated, the destruction of insulation is prevented by an alarm generation and/or inhibition of voltage application. In an embodiment, the insulation state is identified from the ambient humidity of the actuator. In another aspect, if the detected humidity is at a high level that may induce destruction of insulation, the piezoelectric actuator is driven with a low voltage, in order to dehumidity by heat generation. Also shutter control devices for camera, utilizing piezoelectric actuator, are disclosed.

Abstract: A filtration system is disclosed which operates with a single supply pump to achieve backwashing in an expeditious manner. The system includes a fluid supply source for a feed fluid to be filtered, a feed pump in fluid communication with the source and a membrane filter module for separating the fluid into filtrate and retentate streams. A collection reservoir is also provided which has at least two isolated fluid compartments movably separated from one another, one compartment for accumulating filtrate, the other being in fluid communication with the supply pump. In a preferred embodiment the collection reservoir is in the form of a diaphragm unit. At appropriate times, valves are activated to divert the flow of feed material from the supply source to the other chamber of the diaphragm unit. At the same time, flow in the effluent conduit is restricted by suitable means such as a valve, restrictor, pumps or the like, thereby forcing the fluid in the filtrate chamber back through the filtrate conduit to the "underside" of the membrane filter. The resultant pressure creates a back pulse which backwashes the filtration surface of the membrane to remove particular matter thereon.

Abstract: A motion estimating device produces a variable length code motion vector (MV) which signifies the amount of movement of a block of pixel data. The motion estimating device (Figure 3) includes a mean error calculating circuit (100) that successively calculates the mean error between a small (N₁ X N₂) block of pixel data in a current picture (10) and a series of corresponding size blocks of data from a preceding reference picture (30), the reference picture blocks being shifted successively within a larger (M₁ X M₂) block (20) under the control of position coordinate signals (k,1). Each mean error is computed by unit (40) and corresponding variable length code data (D1) is produced by unit (60). Data (D2) based on the difference between the previously computed vector (MV) from delay (70) and the current position coordinates (k,1) is computed by unit (80) in variable length code form. Unit (50) seeks and outputs a minimum value of the thus computed error signals to produce a variable length code vector (MV) with minimised data content.

Abstract: An improved curb section (10) of precast concrete subdivided into modules (10a, 10b, 10c...) by transverse grooves (24) which give the appearance of shorter blocks and provide for fracturing the curb section (10) at those locations. Each module (10a, 10b, 10c...) of the curb section (10) has a rearward T-shaped projection (26). L-shaped projection (28) is formed at each end module (10a, 10c...) of the curb section (10) in proximity to the end face (20) so that L-shaped projections (28) of adjacent curb section (10) form a projection (27) equivalent to a T-shaped projection (26).

Abstract: A probe (10) and method for measuring a gaseous material, such as air, entrained in a solution (S) has a protective sheath member (14) having an ultrasonic transducer (18) encased therein and a reflecting member (42) spatially separated from the active area of face (20) of transducer (18). Upon activation of transducer (18), ultrasonic waves are emitted from transducer (18) that reflect off the gaseous material in the form of bubbles (48) and reflecting member (42) thereby producing correspondingly associated backscattered signals therefrom. Accordingly, the backscattered measurement is operative at low entrained air levels when only a few bubbles or gas (48) are present. Scattering from reflecting member (42) is useful at higher entrained air levels, approaching foam.

Abstract: In regard to a panel (1) in which a short-circuit ring (8) is formed of Al or an Al alloy of a gate wiring line or a source wiring line, the present invention is related to a method for removing the short-circuit ring after a process of inspecting defects of the panel, and provides a method for manufacturing a liquid crystal display panel by cutting a glass substrate outside the short-circuit ring made of Al, and thereafter removing the short-circuit ring by grinding the short-circuit ring while spraying on the substrate a water having a low resistance including something like carbon dioxide gas. 
     According to the manufacturing method, since the low-resistance material of Al of the gate wiring line can be used as the short-circuit ring as it is, the material of Al can be commonly used as a current supply wiring line (6) in subjecting the material of Al to an anodic oxidation process. Therefore, it is not required to form a film of any metal other than Al and pattern the same, which can simplify or reduce the number of processes. 
     Furthermore, since the material of Al is trimmed off by grinding, the Al material is not clawed in cutting the material of Al, which allows the cutting to be achieved without causing any short circuit between adjacent wiring lines nor slipping the tooth in scribing a scratch marking line by means of a scriber.
