摘要： A varifocal lens whose variable focal length can be controlled by, for example, an electric signal, and suitable for use in bar code readers, etc. A varifocal lens comprises a first pressure chamber defined between a glass substrate and a transparent elastic film. The transparent elastic film is faced to the surface of the planar glass substrate having parallel surfaces with a spacer incorporated therebetween to provide the first pressure chamber. A pump is provided adjacent to the first pressure chamber via a communicating path for charging an operating liquid to the first pressure chamber from a second pressure chamber of the pump by electrically deforming the transparent elastic film to form a lens having a variable focal length. The transparent elastic film has a film thickness distribution as such to provide a spherical plane in the central portion thereof and a third order curved surface in the periphery thereof. In this manner, a lens free of aberration can be obtained when a liquid is fed into the first pressure chamber to form a spherical plane.

摘要： An optical data reader including a device for producing a light beam, and a device for changing a condensing position of the light beams before the light beam is reflected from a target such as a bar code. The device for changing the condensing position is either a variable focus lens or mirror, each adapted to change the curvature of the surface of the lens or mirror in order to move the condensing position cyclically and continuously. The variable focus mirror changes the shape of its reflecting surface in response to electrical signals from a driving circuit. Excess pressure within the mirror caused by the mirror surface being attracted inwards is expelled through intake/outlet ports formed in the drive electrode. The variable focus lens alters the focal length of the lens each time the curvature of the surface thereof is changed. Preferably, the curvature of the lens surface is changed by increasing fluid pressure within the lens, while the curvature of the variable focus mirror is electrically driven. Either the variable focus lens or mirror is disposed in the optical path between the light source and the target. The light source is usually a laser or laser diode.

摘要： A micro machining apparatus forms a high-aspect structure having an optional depth in a workpiece at low cost. The apparatus applies high-frequency electric power to the workpiece and a machining electrode, to form a plasma zone in the vicinity of the leading end of the machining electrode. The apparatus guides a reactive gas into the plasma zone to activate the gas. The activated gas is adsorbed by the surface of the workpiece that faces the leading end of the machining electrode. The adsorbed gas reacts with the material of the workpiece and locally etches off the surface of the workpiece. A feed mechanism of the apparatus feeds the machining electrode toward the workpiece according to the progress of the etching, thereby forming a trench in the workpiece. Reaction products of the workpiece and reactive gas produced by the etching adhere to and deposit on the sidewall of the trench and form a protective film for protecting the sidewall from being etched, thereby providing the trench with a high aspect ratio.

摘要： An electrode for electrical discharge machining. This spark-machining electrode improves the accuracy at which the workpiece is machined by electrical discharge machining. The electrode can dispense with a mechanism which scans the spark-machining electrode or the workpiece. A plurality of needlelike electrodes are formed on the surface of the spark-machining electrode. The needlelike electrodes are so arranged that they are present in craters created by their respective adjacent needlelike electrodes. The plural electrodes form a group. The shape of the surface of this group is formed according to the desired shape to be formed in the workpiece. Art electric discharge occurs mainly at the tips of the needlelike electrodes and so the capacitance is smaller than the capacitance of the prior art flat-plate electrode. Also, the energy of a single electric discharge can be reduced. Furthermore, electric discharge at the side surfaces of the needlelike electrodes can be suppressed because of the effect of concentration of electric field.
摘要翻译：放电加工用电极。该火花加工电极通过放电加工提高了加工工件的精度。电极可以省去扫描火花加工电极或工件的机构。在火花加工电极的表面上形成多个针状电极。针状电极被布置成使它们存在于由它们各自相邻的针状电极产生的凹坑中。多个电极形成一组。该组的表面的形状根据要在工件中形成的所需形状形成。艺术放电主要发生在针状电极的尖端，因此电容小于现有技术的平板电极的电容。此外，可以减少单个放电的能量。此外，由于电场浓度的影响，可以抑制针状电极的侧面的放电。
