摘要： In a magnetic head of perpendicular magnetization type having main and sub magnetic poles arranged at both sides of a recording medium, a nonmagnetic supporter holding a high permeability magnetic thin layer of the main magnetic pole is formed by a polycrystalline sintered body substantially composed of titanium carbide and alumina. This polycrystalline sintered product well matches with a recording medium having a cobalt-chromium alloy layer so that the recording medium does not wear for a long time of use, and therefore, so that the contact surface of the main magnetic pole is hardly damaged. The same sintered body may also be used for the sub magnetic pole arranged to be in contact with the recording medium. Some structural improvements are also provided so that undesirable influence due to an adhesive layer adjacent to the magnetic thin layer is removed. One or more additional thin layers may be provided for reducing crosstalk between adjacent tracks. A magnetically shielding block is provided to prevent undesirable influence caused by an external magnetic field.

摘要： A ghost signal erasing system for television receivers in which a variable delay element utilizing the propagation of an elastic surface wave is used. The variable delay element includes a piezoelectric substrate, a plurality of first interdigitated electrode pairs formed on the substrate and a plurality of second interdigitated electrode pairs also formed on the substrate. An elastic surface wave produced by applying a video i-f signal to the first interdigitated electrode pairs is propagated along the surface of the piezoelectric substrate and taken up at the second interdigitated electrode pairs as a delayed a-c signal. By switching the first and second interdigitated electrode pairs to change the combination thereof, various delay times are obtained.

摘要： A CO2 laser beam 12 is converted into a beam of uniform intensity at the position of a phase matching element 15 by an intensity converting element 14 and the phase matching element 15. Then, the uniform intensity beam irradiates a mask 17 containing an aperture variable in size via a variable-magnification projecting optical system 16. At the time of irradiation, the laser beam at the position of the phase matching element 15 is projected onto the mask 17 at a magnification factor most suited to the size of the aperture formed in the mask 17. Further, the pattern of the mask 17 is projected onto a workpiece 19. Thus, a uniform intensity distribution of the laser beam is obtained on the workpiece and high quality laser processing becomes possible.

摘要： A discharge-pumped gas laser has a pressure container filled with a laser gas under pressure and a pair of elongate main discharge electrodes. The main discharge electrodes are disposed in the pressure container in confronting relationship to each other for producing an electric discharge in the laser gas in a main discharge region defined therebetween to excite the laser gas for laser emission. The laser gas is circulated to flow through the main discharge region in a direction perpendicular to the main discharge electrodes. The laser gas in the main discharge region is preionized by an UV preionizer disposed either upstream or downstream of the main discharge region with respect to the direction of flow of the laser beam. The pressure container houses a baffle partition for controlling the laser gas to flow past one of the main discharge electrodes and the preionizer while blocking the laser gas from directly flowing to the other of the main discharge electrodes and the preionizer.
