20100275670 | PRESS WORKING METHOD AND PRESS WORKING APPARATUS - In a press working apparatus, while a servo motor is acting, an upper die is made to come close to a lower die and press working of the first time is conducted on a steel plate. A slider is raised to a movable punch preparation position. A movable punch is protruded from a die face of the upper die by width and locked by a mechanical lock. The upper die is made to come close to the lower die again and the steel plate is pushed with the upper die and at the same time an additional worked portion is pushed and deformed with the movable punch so as to conduct press working of the second time. After the movable punch has been retracted, the slider is raised. | 11-04-2010 |

20100018280 | PRESS-WORKING METHOD, AND PRESS-WORKING APPARATUS - A press-working apparatus capable of forming a clear character line. The press-working apparatus forms a product having a character line. The press-working apparatus comprises an upper die and a lower die arranged across a steel sheet, an upper die mechanism for moving the upper die toward and away from the lower die, a first holder and a second holder for clamping the steel sheet and applying an unwrinkling force to the same, and a control unit for controlling the upper die mechanism and the first holder. The upper die is divided on the character line of the product into a first upper die and a second upper die. The control unit makes the unwrinkling force by the first holder stronger than that by the second holder, so that the steel sheet is press-worked by the second upper die and then by the first upper die. | 01-28-2010 |
20100089119 | FORMING CONDITION DETERMINATION METHOD AND FORMING CONDITION DETERMINATION SYSTEM - A forming speed determination method for determining a forming speed of a press-processing device with a plurality of measurement points on a sheet material to conduct press-forming of the sheet material with a press-processing device at a predetermined forming speed. Strain states at respective points on the press-formed sheet material are plotted on a forming limit diagram including the forming limit curve of a sheet material to produce a strain distribution chart. Subsequently, the closest point to the forming limit curve among the points is defined as a specific measurement point. When this specific measurement point is located in the bulge region, the forming speed of a press-processing device is decreased to be slower than the above-mentioned predetermined forming speed. Meanwhile, when this specific measurement point is located in the draw region, the forming speed of a press-processing device is increased to be faster than the above-mentioned predetermined forming speed. | 04-15-2010 |

20080221488 | METHOD FOR MONITORING LIVING BODY ACTIVITIES, AND OPTICAL FIBER TYPE FLAT SHAPED BODY SENSOR, GARMENT STYLED OPTICAL FIBER TYPE FLAT SHAPED BODY SENSOR AND HUMAN BODY FITTED OPTICAL FIBER TYPE FLAT SHAPED BODY SENSOR USED FOR THE SAME - A living body monitoring activity system detects major activities, or feeble living body activities. In a method for monitoring existence of human movements or living body activities in living environments (e.g., sleeping activities involving a bed, a Futon-mat, a pad, or a Tatami-mat), an optical fiber type flat shaped body sensor including an optical fiber affixed or fitted to a flat shaped body is used, and light is emitted into the optical fiber from a light source, and changes of polarized wave conditions of light propagating in the optical fiber are brought about by changes in form of the optical fiber type flat shaped body sensor caused by human movements or living body activities and are detected by a measuring apparatus for polarized wave fluctuations so human activities or movements are discriminated based on the detected value of the polarized wave fluctuations. | 09-11-2008 |
