Title: Foam molding method
Inventor: NOZAWA AKITOSHI
IPC: B29C39/44
Filed: 1989-09-25
Abstract: PURPOSE:To prevent the dry spot of a cell and a void while obviating blister, cracking and shrinkage at the time of mold release by including a plasticizer at specific rates to a polyol component and an isocyanate component in a foam molding material in a skin integral urethane foam molding method. CONSTITUTION:Polyether polyol is used generally as the polyol component of a foam molding material and an aromatic group polyisocyanate as an isocyanate component. A material made of a vinyl chloride resin is employed normally as a skin. A plasticizer selected from phthalic ester, trimellitic ester, aliphatic bibasic ester, phosphoric ester and epoxidized ester in conventionally known compounds displays a particularly excellent effect as the plasticizer contained in the foam molding material. These plasticizers can be used singly or in the combination of plural kinds, and loadings thereof are kept within the range of the 5-50 pts.wt. plasticizer to the 100 pts.wt. total loadings of the polyol component and the isocyanate component.

Title: Detecting device for combustion state of internal combustion engine
Inventor: MORITA TATSURO
IPC: G01M15/08
Filed: 1985-11-06
Abstract: PURPOSE:To simplify the structure and to reduce the cost by calculating an integral value of P(in-cylinder pressure XDELTAV (fine variation in cylinder capacity) within a limited range near a top dead point of compression and grasping a combustion state. CONSTITUTION:A crank angle position detector 49 outputs a 720 deg. signal of every 720 deg. crank angle and a 1 deg. pulse signal of every 1 deg. crank angle in synchroni zation with the rotation of an engine. Further, a DELTA computing element 61 calculates variation DELTAV in cylinder capacity every time the counter value of a C counter 53 varies. Further, an integrator 63 integrates PXDELTAV to find SIGMAP.DELTAV. Then, a 1 signal synchronizing program is executed at every 180 deg. unit cycle since each cylinder of a four-cylinder engine has a top dead point of compression at intervals of a 180 deg. crank angle. A crank angle position where mean effective pressure Pi in an artificial figure is obtained is within the range of 60 deg. from the top dead point of compression, so in-cylinder pressure P is detected in a period which is 60 deg. before and after the top dead point of compres sion every time a 1 signal is inputted, so that PXDELTAV is calculated on the basis of the detected pressure.

IPC: A61C5/77
Filed: 1989-09-25
Abstract: PURPOSE:To efficiently produce the substitutive of the hard tissue of a living body by forming leaves having the same shape as the shape of the respective parts slicing the hard tissue of the living body by using metals, ceramics or high-polymer material, etc., and laminating and joining the leaves. CONSTITUTION:Positioning holes 2, 3 are bored in the leaves 1a having the same shape as the shape of the respective parts formed by slicing the tooth itself and positioning pins 4, 5 are implanted into the positioning holes 2, 3. The positioning holes of the respective leaves 1b, 1c are matched to the above-mentioned pins 4, 5 and a lot of leaves are laminated and jointed. Finally, the positioning holes of the leave 1d of the uppermost part are fitted to the above-mentioned pins 4, 5 to laminate and join the leaves, by which the substitutive for the tooth is completed. The finishing of the peripheral surface is thereafter executed to complete the production of the substitutive. Diffusion joining, adhering, sintering, etc., are used as the method for laminating and joining. The hard tissue of the living body having the intricate three- dimensional shapes is formed by stacking of the simple two-dimensional shapes. The substitutive for the hard tissue of the living body is thus efficiently produced. Since the stages are fewer, the labor is saved and the accurate substitutive is produced in a short period of time.
