Abstract: A laser beam transmission apparatus comprises a light-incidence optical system (22) converging and focusing a laser beam emitted from a solid-state laser apparatus (1), and an optical fiber (8) which transmits the laser beam that has been converged and focused by the light-incidence optical system. The light-incidence optical system (22) has at least first and second lenses (13, 14) disposed on the same optical path. A first distance (a) between an output end of the solid-state laser apparatus and the first lens or a second distance (b) between the second lens and a light-incidence end of the optical fiber is freely set according to a relational formula based on a focal distance (f1, f2) of each of the first and second lenses.

Abstract: A method of displaying program-related information while the user views a program video mainly and a broadcasting program displaying device to implement the method without making the user's operation complicated and confusing. A picture plane is constructed by two picture planes having a television picture plane (picture plane 1) for displaying the program video which is outputted from a broadcasting program displaying device and further a property state picture plane as another picture plane (picture plane 2). The program video is displayed to the picture plane 1 and an operation picture plane of the broadcasting program displaying device and the program related-information are displayed to the picture plane 2. A broadcasting program displaying device for two-screen construction has functions for display, recording, replay, reservation recording, and the like in response to an instruction from a device which the user operates.

Abstract: A high pressure discharge lamp includes: a quartz glass bulb having an expanded portion and sealing portions; conductive elements, and a pair of electrodes. The conductive elements are airtightly sealed at the sealing portions of the quartz glass bulb. Each electrode of the pair of electrodes is disposed so as to be opposite the other and each electrode is connected to one of the conductive elements. An angle &thgr;1, between a tangent along the inner surface of the expanded portion at a position 0.5 mm away from an origin of one of the sealing portions along the length direction of each electrode and the direction of the length of each electrode is at least about 40°.

Abstract: Disclosed is a process for preparing a cathode structure for impregnated cathodes having desired dimensions by a simplified process without experiencing machining etc. A high-melting-point metal powder is introduced into a mold, and heated with the heater to effect isostatic press molding to provide a cathode structure for impregnated cathodes having a predetermined shape and dimensions by one operation.

Air" wherein Sub. is a transparent substrate; H and L are layers of high refractive index material and low refractive index material, respectively, stacked alternately to form multilayer dielectric coatings; (H.multidot.L).sub.4 stands for a series of four layer pairs each consisting of high refractive index material layer and low reflective index material layer stacked alternately H and L; Air stands for an atmosphere to which the top surface of the multilayer coating is exposed; each of H and L has a thickness of .lambda..sub.0 /4; .lambda..sub.0 is 6328 .ANG.; n.sub.1 is a natural number selected from the group consisting of 3, 5 and 7; and n.sub.2 is a natural number determined by n.sub.2 =9-n.sub.1. Likewise a preferred multilayer structure of the total reflection mirror is represented as "Sub. .vertline.(H.multidot.L).sub.

Abstract: A magnetic head supporting device for supporting a magnetic head for writing information in and/or reproducing recorded information from a flexible magnetic disk. The magnetic head supporting device comprises a holding plate for holding the magnetic head, and a base plate attached to the holding plate and fastened to the carriage of a magnetic disk driving apparatus so that the magnetic head is supported opposite to the magnetic disk loaded on the turn table of the magnetic disk driving apparatus. The holding plate is provided in its upper surface with a positive pressure creating section in its front end to create a positive pressure for floating the magnetic disk, a floating section in its radially opposite sides to float the magnetic disk stably, and a negative pressure creating section in its central area to create a negative pressure for attracting the magnetic disk.

Abstract: A carboximide derivative represented by the general formula: ##STR1## wherein X is ##STR2## Z is alkyl, aralkyl, cycloalkyl, cycloalkylalkyl, alkenyl or arylalkenyl, and Y is a substituted or unsubstituted pyridyl, pyrimidyl or phenyl group, and a pharmaceutically acceptable acid addition salt thereof. The carboximide derivative and acid addition salt are useful for treating diabetes and also for depressing the central nervous system. The carboximide derivative may be produced by reacting a sodium alkoxide represented by the general formula: ##STR3## wherein X and Y have the same meanings as defined above, with Z.Hal wherein Hal is a halogen and Z has the same meaning as defined above.
