| 20120025726 | REVERSED-POLARITY PULSE GENERATING CIRCUIT FOR DIRECT CURRENT PLASMA AND DIRECT CURRENT PLASMA POWER SUPPLY UNIT - A capacitor is connected between direct current voltage terminals, and inductance means is connected between one end of the capacitor and one of load terminals. In a case in which the direct current voltage exceeds a set value, voltage at both ends of the capacitor is shared by the first and second switching elements that are not electrically conductive; in a case in which the direct current voltage is below the set value, the first and second switching elements are electrically conductive on a periodic basis or as needed to output reversed-polarity voltage between load terminals; and in a case in which the first and second switching elements are turned off, voltage at both ends of the capacitor restricts voltage applied to both ends of the first and second switching elements, during a period in which the first and second feedback rectifier elements are electrically conductive. | 02-02-2012 |
| 20110232827 | METHOD OF MANUFACTURING BONDED MEMBER AND BONDED MEMBER MANUFACTURING APPARATUS - It can prevent extension of the time required for bonding, even when relatively large members are bonded. a bonded member manufacturing apparatus comprises a first holder 11 for holding a first member D, a second holder 12 for holding a second member E, an application device 40 for applying the intermediate substance G to a first bonded surface Df, a moving device 20 for moving the first holder 11 and/or the second holder 12, and a controller. The controller controls the first holder 11, the second holder 12 and the moving device 20 so that a first extended plane De and a second extended plane Ee are arranged such that the first extended plane De and the second extended plane Ee oppose each other in parallel and such that a range where the first bonded surface Df overlaps with the second bonded surface Ef is equal or smaller than a predetermined range when viewed in a direction of the thickness, and then so that the first member D is moved relatively to the second member E in a direction that the range where the first bonded surface Df overlaps with the second bonded surface Ef gradually increases when viewed in the direction of the thickness while maintaining a distance between the first extended plane De and the second extended plane Ee. | 09-29-2011 |
