  • Publication number: 20130316297
    Abstract: Dentition three-dimensional data and jaw-bone three-dimensional data are collected from a patient and they are combined. According to the combined data, dental crown data for making up for data on a lost tooth and occlusion data on a dental crown represented by the dental crown data are created. When an occlusion force according to the occlusion data is exerted on the occlusion face of a dental crown, a mechanical evaluation factor is produced in a jaw bone. The mechanical evaluation factor produced near the place where an artificial tooth root supporting a dental crown is to be implanted is calculated. The implantation place is determined so that the mechanical evaluation factor may be smaller and the mechanical load on the jaw bone from the opposed tooth during mastication may be lighter.

  • Publication number: 20080145440
    Abstract: According to the present invention, an early-phase release amount of cisplatin (CCDP) is reduced and a release of cisplatin is maintained over a long period of time, such that an anticancer effect against cancer cells is enhanced while side effects are reduced. In this manner, a life prolongation effect for patients is enhanced. A microparticle preparation contains cisplatin that is intercalated into double-helical DNA. The microparticle preparation stably retains cisplatin and exhibits an excellent slow-release property. Accordingly, even when cisplatin containing severe toxicity is used, the side effects can be suppressed and an excellent anticancer effect can be provided over a long period of time.

  • Patent number: 7248996
    Abstract: A highly reliable vehicle driver's fatigue evaluating method is provided, which is capable of quantitatively calculating a degree of fatigue of a driver seated on a seat. The degree of fatigue of the driver seated on a seat is quantitatively calculated based on an amount of rearward deflection of a lower part of a backrest portion of the seat, a load applied downward to a front part of a seating portion of the seat, and a load applied rearward to an upper part of the backrest portion, in a state of the driver being seated on the seat.

  • Publication number: 20050064387
    Abstract: The present invention provides a method of and a device for measuring bulk modulus of a fine specimen using a measurement chamber, a reference chamber for comparison, and a differential pressure measurement device for detecting the pressure difference between both chambers. The specimen is contained in the measurement chamber, and in a state where both chambers are set under the standard atmospheric pressure. Then both chambers are set under the compression atmospheric pressure higher than the standard atmospheric pressure and the pressure changes are periodically given to both chambers. The initial volume of the specimen is detected from the differential pressure signals of both chambers when it is under the standard atmospheric pressure and the compression volume of the specimen is detected from the differential pressure signals of both chambers when it is under the compression atmospheric pressure. The bulk modulus of the specimen is measured by computing and analyzing these detected signals.

  • Patent number: 6306785
    Abstract: A living tissue replacement of crystallized glass having bioaffinity and mechanical strength is briefly obtained simply by pressure molding or machining without using a special equipment. A glass material having a softening point below its crystallization temperature and exhibiting viscous flow at temperatures below its melting point is heated at a temperature above its Tg and pressed at the temperature to mold to a desired shape, thereby manufacturing a living tissue replacement such as a dental crown. Molding can be done under a pressure of up to 20 MPa.
