IPC: G01N29/44
Filed: 1984-09-06
Abstract: PURPOSE:To improve measuring operability sharply and to attain more precise measurement by automating the attenuation ratio setting operation of an attenuator to include a decibel value processed by the attenuator always within a highly accurate reading range without manual operation. CONSTITUTION:The arithmetic processing of e=20log c/d is executed on the basis of an output value (c) obtained by A/D converting an analog signal attenuated by the attenuator 6 and a reference value (d) obtained from a reference value oscillation circuit 8 to obtain an attenuation decibel value (e). The calculated attenuation decibel level (e) is compared with a set-up attenuation decibel value (f) obtained from a set-up attenuation decibel value oscillation circuit 10 by a comparator 11. The attenuation ratio of the attenuator 6 is automatically set up and changed by a setting/changing means 12 on the basis of said compared result so that the calculated attenuation decibel value (e) is '0' or less and the set-up decibel value (f) or more, i.e. the value (e) is included within the highly accurate reading range.

IPC: H01C17/22
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To enable a product conventionally discarded as a defective item to be finished by a method, wherein a resistance value is measured after the secondary baking step to be rebaked for correcting the resistance value for case the where the resistance value is out side the allowable range. SOLUTION: A finished product is manufactured through the first baking step, the second baking step and the outer layer-forming step. At this time, the resistance value is measured after the second baking step and if the measured value is out of the allowable range, the re-baking step added for correcting the resistance value prior to starting the outer layer-forming step. Next, the resistance value is plus + shifted by a required value and after confirming that the required resistance value is within the allowable range by the resistance value measurement, the resistor is fed to outer layer electrode- forming step, as the next step for finishing the resistor. At this time, if the resistance value is out of the allowable range at the measurement after the re-baking step, the baking meeting the baking requirements which meet the error value is to be further repeated.

IPC: C04B35/45
Filed: 1987-07-27
Abstract: PURPOSE:To obtain superconductor particles in which transition temperatures are equalized by holding powder material mixed with superconductor particles having different transition temperatures at intermediate temperature of the different transition temperatures, and applying a static magnetic field thereto. CONSTITUTION:A temperature TM of the intermediate of the Tc1 (transition temperature) of the highest Tc and Tc of the particle having next higher Tc is held in the superconductor particles having different Tc, and the superconductor particles having different Tc are filled in an upward magnetic field 5 of a magnet 6. Then, since the particles having the Tc1 of Tc are superconductor particles (Tc1) 3, they are floated on the magnet 6 by means of Meissner effect. However, since the particles having Tc except the Tc1 do not become the superconductor at this temperature, they are not floated from the magnet 6. Accordingly, when only the floated particles are selected, the superconductor particles having Tc1 can be gathered.

Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a printing apparatus which can surely prevent an object to be recorded from being dirty by prohibiting a movement of a main body case in an opposite direction. SOLUTION: In printing, while a timing roller 21 is kept in touch with a surface of a recording paper 15, a main body case is moved in a print direction. The timing roller 21 is consequently rotated, and a recording head carries out predetermined printing. On the other hand, when the main body case is to be moved in an opposite direction to the print direction due to an erroneous manipulation, a one-way clutch mechanism 35 intermediately acts thereby to prohibit an inverse rotation of the timing roller 21, and accordingly the main body case is surely prevented from being moved to the opposite direction.
