| 20080295564 | Transfer Press Machine - A transfer press machine which can accurately and promptly check interference and can be easily handled is provided. The transfer press machine includes an interference check device including: a data-conversion constituent element storage section which stores a press-side data-conversion constituent element and a transfer-side data-conversion constituent element in a state of being placed in virtual space to have the same relative positional relationship as in real space; a virtual press operation control section which causes the press-side data-conversion constituent element to perform a virtual press operation in the virtual space according to a press motion; a virtual transfer operation control section which causes the transfer-side data-conversion constituent element to perform a virtual transfer operation in the virtual space according to a transfer motion; a virtual synchronization timing information generation-output section which generates and outputs virtual synchronization timing information, and a virtual interference determination section which determines whether or not interference occurs between the press-side data-conversion constituent element and the transfer-side data-conversion constituent element during a transfer press cycle. | 12-04-2008 |

| 20120111207 | CONTROL DEVICE OF SERVO PRESS AND METHOD FOR CONTROLLING SERVO PRESS - A control system of a servo press and a control method are provided for preventing an overload on a pressure capability of a press and a torque capability of a drive system. A control device of a servo press for pressing by transferring a drive force of a servomotor to a slide via a drive mechanism includes: a motion calculation unit for calculating slide target position data; a torque calculation unit for calculating process torque for pressing and control torque for speed change of the servo motor on the basis of slide target position data; a process system limit unit for limiting the calculated process torque to predetermined process limitation torque; and a drive system limit unit for limiting combined torque of the limited process torque and the control torque to predetermined drive limitation torque. The servo motor is driven on the basis of a command of drive limitation torque. | 05-10-2012 |

| 20100105802 | CURABLE COMPOSITION FOR DENTAL PURPOSES - A curable composition for dental use, containing a polymerizable monomer, inorganic particles (A) having irregular shapes and an average particle size of from 1.0 to 5.0 μm, wherein the inorganic particles (A) are surface-treated with a silane coupling agent (a) represented by the formula (I): | 04-29-2010 |
| 20110046261 | DENTAL COMPOSITION AND COMPOSITE RESIN - A dental composition of the present invention includes: a polymerizable monomer component (A); and an amorphous filler (B) having an average particle size of 1 to 20 μm and including silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The dental composition contains 20 to 500 parts by weight of the filler (B) per 100 parts by weight of the polymerizable monomer component (A). The dental composition has a viscosity of 10 to 800 Pa·s. It is preferable that the filler (B) contain spherical particles, and that the percentage of the spherical particles in the filler (B) be at least 60%. | 02-24-2011 |
