摘要： PROBLEM TO BE SOLVED: To suppress subsequent dripping of a fluid and bring a seal body and a plunger into a separable contact in an injector.
SOLUTION: An injector 10 comprises a cylindrical barrel 12, a movable body 14 housed in the barrel, and a plunger 16 coming into separable contact with the movable body 14. The movable body 14 includes a main body 14a having an outer diameter smaller than an inner diameter of the barrel 12, a disk-shaped seal body 14b disposed on the main body 14a and including an outer circumferential end brought into close contact with an inner circumferential surface 12e of the barrel 12, and at least one projecting portion 14c projecting from the main body 14a toward the inner circumferential surface 12e of the barrel 12. A distance from a central axis of the movable body 14 to a leading end of the at least one projecting portion 14c is smaller than a half of an outer diameter of the seal body 14b.

摘要： A denture grinding machine includes: a denture-holding table for holding dentures; a grinding tool for grinding the dentures held on the denture-holding table; a main body for holding the grinding tool; a moving mechanism for causing relative movement between the denture-holding table and the main body; and a driving mechanism for relatively driving the main body and the denture-holding table. The moving mechanism moves relatively the denture-holding table and the main body in three-dimensional coordinate directions based on grinding portion data, and the grinding tool performs grinding of the denture occlusal surface from a direction perpendicular to the occlusal surface.

摘要： An artificial tooth where an occlusal surface is formed by grinding has a reference point that represents a position and an angle of the artificial tooth when an occlusal surface of the artificial tooth is obtained by an occlusal-surface form measuring apparatus. The reference point is a convexed spherical surface or a concaved spherical surface arranged on the occlusal-surface. The convexed spherical surface is fit to the concaved spherical surface when the maxillary artificial tooth and mandibular artificial tooth are occluded. The occluding portion of the artificial tooth has a grinding portion.

摘要： A jaw-relation reproduction condition is determined by measuring a jaw movement of a patient, and reproducing a jaw state of the patient on an occlusion-state reproducing apparatus in accordance with the jaw-relation reproduction condition. Dentures are arranged on the apparatus in accordance with the jaw-relation reproduction condition to prepare pre-grinding dentures. Denture data with reference points which is three-dimensional image data containing reference points that represents a positional relationship between the jaw-relation reproduction condition and the dentures and an occlusal surface of the dentures. An occlusion state of the denture data with the reference points is reproduced by using the jaw-relation reproduction condition on a three-dimensional image. Grinding data of a grinding portion is determined under a dynamic condition or set condition from a portion surrounded by an image of upper and lower jaws on the three dimensional image in a reproduced occlusal state. The denture data with reference points having grinding data is prepared. Grinding of the pre-grinding denture is carried out based on the reference points denture data with grinding data.
