摘要:
An electrode pattern can be formed on a ceramic electronic part by removing part of a conductive film formed on the surface of a sintered ceramic body, by the following steps: 1) forming a conductive film on the surface of the ceramic body; 2) placing a mask on the conductive film, the mask having an opening corresponding to the electrode pattern to be formed, 3) blasting the ceramic body with an abrasive material so as to remove the conductive film in a region corresponding to the opening in the mask, and 4) removing the mask from the conductive film. The mask is reusable for being repeatedly placed on and removed from conductive films on respective ceramic bodies.

An information processing apparatus includes an allowable output amount storage unit that stores allowable output amounts of respective combinations of a user and a predetermined totalization period; a total output amount recording unit that records total output amounts of the respective combinations of a user and a predetermined totalization period; and a processing unit that receives, from a user, an instruction that designates image forming information and an instruction to perform image formation on the basis of the designated image forming information, and performs image-formation-related processing for the designated image forming information if a value obtained by adding together an output amount of the image-formation-instructed image forming information, a sum of total output amounts of the user, and a sum of output amounts of pieces of particular image forming information specified by the user is smaller than or equal to an allowable output amount of the user.
摘要:
The invention relates to a microporous membrane, which is provided with high safety even under a condition that the interior temperature of a battery becomes high, and which has high permeability and high mechanical strength at the same time.The polyolefin microporous membrane is characterized by a membrane thickness of 5 to 50 μm, a void content of 30 to 60%, a gas transmission rate of 40 to 300 sec/100 cc/20 μm, a piercing strength of not less than 2.5 N/20 μm and a break through temperature of not lower than 110° C.The separator in accordance with the present invention is used to exhibit high safety under a high temperature condition as well as high permeability, and therefore it is particularly useful as a separator for miniaturized high capacity batteries of a non-aqueous electrolytic solution type.
