IPC: G11B7/085
Filed: 1985-03-11
Abstract: PURPOSE:To prevent the occurrence of spot aberration on the surface of a disc by relaxing the impact applied to a carriage or the like within a certain limited range when the carriage collides with a stopper. CONSTITUTION:If a carriage 8 runs away to collide with a right stopper 21, a right sliding plate 20 supporting the stopper 1 is moved slightly right against a spring 20a by its force. The impact of the carriage 8 is absorbed by the spring 20a in this case. If the carriage 8 runs away to collide with a left stopper, the impact is absorbed similarly. Since the impact applied to the carriage 8 or the like is relaxed within a certain limited range when the carriage 8 collides with stoppers 21, the deviation of optical system parts, the distortion of the carriage 8, and the occurrence of spot aberrations on the overall disc surface are prevented effectively, and the destruction of a jacket and a pickup is prevented in an autoloading mechanism.

IPC: H02B5/00
Filed: 1995-03-08
Abstract: PURPOSE: To equalize the voltage on each zinc oxide element by using the zinc element which can be used at an electric field higher than the conventional electric field by a specified number of times, and providing a lightening arresters having the discharge voltage, higher than that of a standard lightening arrester by specified %, in the vicinity of the opening end of a gas insulated switchgear. CONSTITUTION: For lightening arresters B1 and B2, zinc oxide elements, made of new composition that can be used in the electric field higher than the electric field used in standard lightening arresters A1 and A2 by about 1.5 times, are used. Therefore, the length of the lightening arrester B1 and B2 can be made shorter than the length of the lightening arresters A1 and A2 by 1/1.5 or less. Furthermore, the discharge voltage is made 10-30% higher. Therefore, the energy, absorbed by the lightening arresters B1 and B2 for the short-time overvoltage is less than that of the lightening arresters A1 and A2, and the size can be made compact.  As a result, the voltages on the respective zinc oxide elements can be more equalized since the length of the lightening arrester B1 is shorter than the conventional value, and the transformer station, wherein insulation coordination is balanced as a whole and the reliability is high, is obtained.

Abstract: PURPOSE:To obtain an ink jet recording material excellent in ink receptivity and particularly in density and clearness of recorded images, by providing a humectant in a ink-receiving layer and/or on the surface of th layer, in a recording material comprising a base and the ink-receiving layer provided thereon. CONSTITUTION:A recording material comprises a humectant in an ink-receiving layer thereof and/or on the surface of the layer. The ink-receiving layer is a non-porous part for receiving and holding an ink on the face side of the recording material, and is formed of a hydrophilic resin according to performances required of the recording material (ink absorptivity, surface properties, strength of layer, etc.). The humectant has excellent moisture adsorptivity, enhances the adsorptivity of the ink-receiving layer, and prevents the water in the layer from escaping. Therefore, the humectant is a substance superior to the hydrophilic resin (which is a main constituent of the ink-receiving layer) in hydroscopicity and moisture retention. It is preferable that the amount of the humectant is 0.1-50wt% based on the amount of the ink-receiving layer. The thickness of the ink-receiving layer, which is provided on a base, is usually 1-200mum.
