    • A method of manufacturing an image forming apparatus having a plurality of electron-emitting members, with row direction wires and column direction wires, in a matrix, and a dielectric layer between the row and column wires. A resist precursor layer is formed by imparting and drying a first photosensitive paste. A second precursor layer is formed by imparting a second photosensitive paste onto the first precursor layer, and by drying the second paste. A precursor pattern is formed by exposing a layered product of the first layer and the second layer through a mask. The exposed layered product is developed, and the dielectric layer is formed by baking the precursor pattern. A shrinkage ratio of the second layer after the baking to the second layer before the baking is larger than a shrinkage ratio of the first layer after the baking to the first layer before the baking.
    • 一种制造图像形成装置的方法,该图像形成装置具有多个电子发射部件,具有行方向导线和列方向布线,矩阵状以及行和列线之间的介电层。 通过赋予和干燥第一感光膏形成抗蚀剂前体层。 通过在第一前体层上施加第二感光浆料并通过干燥第二浆料形成第二前体层。 通过掩模使第一层和第二层的层叠体曝光来形成前体图案。 显影出的层叠体,通过烘烤前体图案而形成电介质层。 烧成前的第二层的第二层与烘烤前的第二层的收缩率比烘烤前的第一层的烘烤后的收缩率大。

    • It is an object of the present invention to provide an ultrasonic transducer, which is so configured as to reduce the variations in characteristics, thereby to enable the stabilization of the precision, as well as to enable the improvement of the durability, and the like, a method for manufacturing the ultrasonic transducer, and an ultrasonic flowmeter. In order to attain this object, in accordance with the present invention, the ultrasonic transducer is so configured as to include a piezoelectric element and an acoustic matching layer, wherein the acoustic matching layer is made of a dry gel of an inorganic oxide or an organic polymer, and a solid skeletal part of the dry gel has been rendered hydrophobic. With this configuration, it is possible to obtain the ultrasonic transducer having an acoustic matching layer 3 which is very lightweight and has a small acoustic impedance due to the solid skeletal part of the dry gel which has been rendered hydrophobic. Further, it is also possible to obtain the ultrasonic transducer which shows a narrow range of characteristic variations, and is stable due to the high homogeneity of the dry gel.
