Title: Method for isomerizing wax and production of base oil for lubricating oil
Inventor: ARIMA YOSHIO
IPC: C10G73/38
Filed: 1994-06-20
Abstract: PURPOSE:To provide a method for isomerizing a wax by which a base oil for a lube oil, excellent in optical stability and having a high viscosity index is economically obtained in a high yield by using one kind of catalyst. CONSTITUTION:This method for isomerizing a wax is to regulate the contact temperature in a reactional zone on the upstream side to 350-450 deg.C and that on the downstream side to a lower temperature than the contact temperature in the reactional zone on the upstream side by >=35 deg.C in bringing the wax into contact with a catalyst for isomerizing the wax containing at least one metallic component selected from nickel, cobalt, molybdenum and tungsten and, as desired, phosphorus supported on a refractory inorganic oxide carrier under 50-150kg/cm<3> pressure of hydrogen. Furthermore, this method for producing a base oil for a lube oil having <=0.01wt.% content of 4-membered ring condensed polycyclic aromatic components having the pyrene ring is to dewax a product oil obtained by the method for isomerizing the wax.

Title: Production of polyester film for magnetic recording flexible disk
Inventor: HOSOI MASAHIRO
IPC: B29C55/12
Filed: 1987-06-29
Abstract: PURPOSE:To decrease the anisotropy of an intra-surface dimensional change by subjecting a biaxially stretched and heat-fixed polyester film to a heat treatment at a prescribed temp. while elongating the film in a transverse direction by a stenter and subjecting the film to a relaxing heat treatment in a contactless state by a floating heat treatment system. CONSTITUTION:The biaxially stretched and heat-fixed polyester film is first heat treated at the temp. lower than the temp. of the heat fixing while the film is subjected to the elongation, more particularly 1-7% elongation in the transverse direction in the stenter to form the heat-treated film of which the longitudinal shrinkage when the film is held for 72hr under the temp. and humidity conditions of 60 deg.C and 80% RH is 0.05-0.2% and the transverse shrinkage is larger by 0.02-0.2% than the longitudinal shrinkage. While the traveling tension of this heat-treated film is kept under 4.0-10kg/cm<2>, the film is subjected to the relaxing heat treatment for >=5sec at 90-110 deg.C in the contactless state to adjust the shrinkage to <=0.03% in both directions. The dimensional change is thereby decreased and the intra-surface anisotropy thereof is decreased.

Title: Liquid fuel combustion apparatus
Inventor: UNO KATSUHIKO
IPC: F23N3/08
Filed: 1988-06-28
Abstract: PURPOSE:To prevent an excessive large flame when the combustion rate is changed from low to high by providing an air supply device that supplies air into a combustion chamber linking with a wick adjusting device, and a controller that reduce the capacity of the air supply device gradually and stops it after a certain period of time when the combustion rate is changed from low to high. CONSTITUTION:A cylindrical wick 1 that is installed vertically is held free to move up and down between a wick internal drum 4 and a wick external drum 5, and the lower end of the wick 1 is submerged into liquid fuel. The exposed height of the top of the wick 1 in a combustion chamber 11 is adjusted by a wick adjusting device 14 to regulate the combustion rate. A blower 15 as an air supply device is installed in the wick internal drum 4 so as to produce an air current flowing from the top toward the bottom. A controller 16 that regulates the output of the air fan is linked with a wick adjusting device 14. In this constitution described above, when the combustion rate is rapidly changed from weak to strong, the blower 15 is started to supply air into an internal combustion drum 3, and the combustion load is increased, so that generation of a excessive flame can be prevented. However, when the blower 15 is stopped, the flame grows rapidly. This phenomenon can be solved by providing the controller 16 that reduces the output of the blower 15 gradually and stops it after a certain period of time.

IPC: H02K9/06
Filed: 1988-06-28
Abstract: PURPOSE:To prevent vibration or noise by sandwiching a synthetic resin diffuser with a metallic bearing fixing frame body and a metallic supporting board. CONSTITUTION:A bearing 23 for bearing the rotary shaft 33 of a rotor 32 and a bearing fixing frame body 22 are made of metallic material.

Furthermore, the bearing fixing frame body 22 is secured to a synthetic resin diffuser 9 with the diffuser 9 being held by the frame body 22 and a metal supporting board 27. Consequently, even under high temperature or even when high temperature state and cold state are repeated through driving/stopping of a motor fan 2, the fastening force of the bearing fixing frame body 22 with respect to the diffuser 9 does not lower, and the fixing does not loosen.
