Abstract: PURPOSE:To make it possible to form a microscopic pattern in a highly precise manner by a method wherein, after a film has been grown on the main surface of a wafer, the film deposited on the rear surface of the wafer is removed by etching by protecting the water main surface with a resist film, and then the wafer main surface is selectively exposed and patterned. CONSTITUTION:After a film 2 has been grown on the main surface 1S of a wafer, the film 2 which is deposited on the rear surface 1B of the wafer is removed by protecting the wafer main surface 1S with a resist film 3. Then, the wafer main surface 1S is selectively exposed and patterned using a lithographic technique. To be more precise, by removing by etching in advance the film 2 deposited on the rear surface 1B off the wafer, the exposed surface can be flattened without curving even when the wafer 1 is chucked to an exposing device. As a result, a blooming can be reduced, and a pattern can be formed in a highly precise manner.

Filed: 1985-06-18
Abstract: PURPOSE:To prevent a printing paper from jamming during use of an automatic paper supply device, by controlling a driving current for a paper-feeding motor in accordance with whether the automatic paper supply device is mounted or not. CONSTITUTION:When the automatic paper supply device 20 is used by mounting it on a main body of the printer, a transistor TR2 is turned OFF by a controlling signal S2 from a paper-feeding motor controller 1. By this, a reference current obtained by a reference current setter 5 is relatively increased, so that a relatively high voltage is supplied from the setter 5 to a comparator 4 as a reference voltage VR. When the printer is used by detaching the automatic paper supply device 20 from the main body of the printer, the transistor TR2 is turned ON. By this, a relatively low voltage is supplied from the setter 5 to the comparator as a reference voltage VR. Thus, the current to be passed to the motor 17 is varied according to the presence or absence of automatic paper supply, whereby a torque generated by the motor 17 is controlled.

IPC: H01M10/39
Filed: 1984-06-27
Abstract: PURPOSE:To improve the charge-and-discharge efficiency of a sodium-sulfur battery by using a positive electrode consisting of fiber layers impregnated with sulfur the fiber densities of which increase as they become more apart from the solid electrolyte. CONSTITUTION:A sack-like solid electrolyte tube 1 made of beta-alumina and a positive electrode 11 prepared by impregnating conductive heat-resistant graphite fiber with sulfur, are installed in a positive case 2. The positive electrode 11 consists of the first, the second and the third layers 12, 13 and 14 which are closer to the solid electrolyte tube 1 in that order. The fiber densities of the layers 12, 13 and 14 increase in that order. A sodium-sulfur battery is constituted by combining the thus formed positive body with a negative case 3 packed with sodium 5 used as a negative active material. Because of the above structure, a circulating flow of the active material occurs in the positive electrode 11, thereby actively supplying the active material to inside the reaction area and actively transferring the active material to outside the reaction area. Consequently, it is possible to improve the charge-and-discharge efficiency of the battery and to increase its charge-and-discharge capacity.
