摘要:
The invention relates to a novel polypeptide participating in biotin biosynthesis of plant, a polynucleotide encoding the said polypeptide, a method for inducing plant growth inhibition by suppressing the expression or function of the said polypeptide, resulting in inhibition of biotin biosynthesis, and a method for identifying herbicidal compounds that inhibit the expression or function of the said polypeptide. Biotin biosynthesis is an essential process for the growth of plants, however, the process is not present in both human and animals. Therefore, the compounds suppressing the expression or function of the novel polypeptide that relates to biotin biosynthesis can be effectively used as a new herbicide doing human and animals no harm.

A method for electrically connecting a thin film electrode to a connecting terminal on an active matrix in the manufacture of a thin film actuated mirror is disclosed. The method includes the steps of: forming a thin film sacrificial layer having an empty cavity on top of the active matrix; forming an elastic, a second thin film and a thin film electrodisplacive layers, successively, on top of the thin film sacrificial layer including the empty cavity; forming a contact hole extending from top of the thin film electrodisplacive layer to top of the connecting terminal; forming a first thin film layer on top of the thin film electrodisplacive layer including the contact hole; patterning the first thin film, the thin film electrodisplacive, the second thin film and the elastic layers, respectively; and removing the thin film sacrificial layer, thereby forming the thin film actuated mirror.

An inventive array of thin film actuated mirrors is provided with an active matrix having an array of switching devices, an array of actuating structures and an array of mirrors, wherein each of the actuating structures is cantilevered on the active matrix, and each of the switching devices is positioned on the active matrix beside the position at which each of the actuating structures is cantilevered. In the array, during the operation of the array, since each of the mirrors is connected to the actuating structure through a recessed portion thereof, the mirror stays planar, allowing more accurate and effective reflection of the light beams, which will, in turn, enhance the overall optical efficiency of the array. Furthermore, since the active matrix has the array of switching devices is located beside each of the actuating structures, not directly therebelow, an electrical connection between each of the switching devices and the actuating structure can be made after all of the high temperature processes in the manufacture of the array have been completely, thereby minimizing the effects thereof.

An array of M.times.N thin film actuated mirrors includes an active matrix including a substrate with an array of M.times.N pairs of connecting terminals and an array of M.times.N transistors, and an array of M.times.N actuating structures, each of the actuating structures having an actuating and a light reflecting portions, wherein the actuating portion further includes a first and a second parts. Each of the actuating structures is provided with a first thin film electrode, a thin film electrodisplacive member, a second thin film electrode, an elastic member and a first and a second conduits. Since the first thin film electrode in the first part is electrically connected individually to the bias source, and the second thin film electrode is electrically connected individually to one of the transistor, each of the actuating structures is electrically disconnected with other actuating structures in the same row or column in the array, thereby allowing the bias signal and the electric signal to be applied individually to each of the thin film actuated mirrors.

An array of M.times.N thin film actuated mirrors for use in an optical projection system comprises an active matrix, an array of M.times.N supporting members, and an array of M.times.N thin film actuating structures. Each of the actuating structures includes a first, an electrodisplacive, a second layers and an elastic layer, wherein the first and the seconds layers are placed on top and bottom of the electrodisplacive layer, and the elastic layer is placed on bottom of the second layer. The first layer is divided into a proximal and a distal ends. In each of the actuated mirrors, the proximal end of the first layer is connected to a conduction line pattern to thereby act as a bias electrode and the second layer is connected electrically to one of the transistors through a conduit placed in each of the supporting members to thereby act as a signal electrode. The distal end of the first layer functions as a mirror for reflecting the light beam.
