    摘要: One of commercial AC voltages is coupled to power supply terminals from one of commercial AC power supplies. The AC power supplies belong to either a first group providing higher voltages or a second group providing lower voltages. A rectifier rectifies the AC voltage applied to the power supply terminals, and a rectified voltage is developed between two rectifier output terminals. A switching unit operates to connect voltage-boosting converters selectively in series and in parallel between the rectifier output terminals. Inverters are connected in the output sides of and in association with the respective voltage-boosting converters for converting DC voltages from the associated voltage-boosting converters to high-frequency voltages. The high-frequency voltages are voltage-transformed by associated voltage-transformers, and the voltage-transformed high-frequency voltages are converted into a DC voltage by a rectifier circuit and a reactor. The DC voltage is developed between output terminals of the apparatus. A switching control unit controls the switching unit so as to connect the voltage-boosting converters in series between the rectifier output terminals when a commercial AC power supply of the first group is connected to the power supply terminals, while connecting the voltage-boosting converters in parallel between the rectifier output terminals when a commercial AC power supply of the second group is connected to the power supply terminals.

    摘要: A conductor is wound around a magnetic core to form a plurality of conductor turns. The conductor turns are spaced from one another by a substantially equal spacing d. An insulating layer is disposed between the conductor turns and the magnetic core. An insulating member is wound around the magnetic core in such a manner as to be located in the spaces between and in contact with adjacent ones of the conductor turns.

    摘要: An automatic photographic developing apparatus for photosensitive materials includes a number of processing baths which are filled with processing solutions of different types for processing silver halide coated photosensitive materials. A same number of solution tanks communicated with the respective processing baths are provided for supplying the processing solutions, produced by dissolving solid agents, to the respective processing baths. Each of the solution tanks is protected with an openable cover and is provided with a guide along which the respective solid agents can be loaded into the respective solution tanks for dissolution as the solid agents run down by their own weight. The guide is pivotably mounted for movement between a guiding position and a non-guiding position and is urged by a return spring so that the guide can automatically return to the guiding position.

This apparatus has a thin film forming chamber having a laser-transparent laser entrance window, a target being provided in the thin film forming chamber and containing components of an oxide superconductor, a laser beam source for irradiating the target with a laser beam from the exterior of the thin film forming chamber through the laser entrance window, and apparatus for controlling power of the laser beam which is applied to the target for preventing the power of the laser beam, being applied to the target, from reduction by contamination of the entrance window caused by scattered particles. According to the present invention, it is possible to form an oxide superconducting film having high and uniform characteristics even if a long time is required for film formation, thereby attaining a remarkable effect in improvement of superconductivity of a large area oxide superconducting film.
