Title: Surface treatment of artificial tooth root
Inventor: KAWAHARA HARUYUKI
IPC: A61C8/00
Filed: 1989-03-15
Abstract: PURPOSE:To obtain the artificial tooth root which has no harm on the human body, has excellent bioaffinity, high surface hardness, mechanical strength, and good machinability, is safe and inexpensive and is highly aesthetic by using pure titanium for a base material and forming a titanium nitride layer having a specific film thickness on the surface of the base material by a low-temp. ion plating method. CONSTITUTION:The titanium nitride having the average film thickness ranging 0.5 to 5.0mum and having >=2000Hv hardness is formed in a 10 to 300 deg.C on the surface of the base material by the ion plating method; in addition, the color tones of the base material are changed without changing the film layer of the titanium nitride layer. The change of the various gradation of the golden color specific to titanium nitride according to a requirement without changing the film thickness of the titanium nitride is attained by controlling the evaporation rate of the titanium and the amt. of the gaseous nitrogen to be introduced at the time of the ion plating. This is attained without changing the film thickness of the titanium nitride to be formed.

Title: Control method for industrial robot
Inventor: KATO HISAO
IPC: B23Q7/04
Filed: 1989-03-14
Abstract: PURPOSE:To prevent various things unacceptable from taking place accompanied with contact between holding pawls and a heavy work piece by holding the heavy work piece by the chuck section of a machine tool, and thereby lowering a vertical moving mechanism at the base section of a robot thereafter by the amount of the deflection of the tip end of the robot which is required in advance, so as to release a hold section. CONSTITUTION:At the time of loading, a heavy work piece 10 is held by the chuck section 13 of a machine tool 11, the lifting shaft 2 of a robot is lowered thereafter by the amount of the deflection of the tip end of the robot which is required in advance so that the hold section 9 of the robot is thereby released. When the hold section 9 is released, the tip end of the robot goes up to the original point so as to be restored. Since the tip end of the robot is however lowered in advance by the amount of its deflection, the center of the heavy work piece 10 is thereby consistent with the center of the hold section 9. This can prevent the hold section 9 from coiliding against the heavy work piece 10 while its attitude is tilted, thereby making it possible to prevent things unacceptable such as the manufacture of poor products, the destruction of machine tools and the like from taking place.

Title: Manufacture of crystalline resin plate
Inventor: NAKAGAWA YOSHITAKA
IPC: B29C43/58
Filed: 1983-04-07
Abstract: PURPOSE:To enable the manufacture of the product without sink marks in a thick section part to be achieved by heating the mold surfaces corresponding to the side surface of the thick section part and the upper and lower surface of a thin section part, when the plate like product having the side surface of the thick section part and the thin section part is pressed and cooled. CONSTITUTION:At molding a plate like product, after molds 4 and 5 have been preheated to the temperature equal to or higher than the crystallization beginning temperature of crystalline resin stock 14 o be molded, the female mold 5 and the male mold 4 are pressurized under 2- 10kg/cm<2> pressure by a pressing machine. Saidmolds are continuously cooled, while filling the stock 14 in the portions which are to become a thick section part and a thin section part after molded. At this cooling time, the cooling and solidifying speed on the side surface of the molded article and the upper and lower surfaces of the thin section part of a molded article are regulated by the intervening of heating elements. Conversely, the cooling of the upper and lower surfaces of the thick section part are accelerated. Therefore, the cooling and solidifying speed of the thin section part to the center of molten resin is suppressed, and the cooling and solidifying of the side surface of the thick section of a molded plate are also controlled. Accordingly the upper and lower surfaces of the thick section part or its side surfaces are solidified, while the center of the thick section part is yet in unsolidified state, whereby no sinkmark occurs.
