Patent JP-S579651-A (JP)
Title: Paper feeder mechanism
Inventor: KIMURA NOBUYOSHI
IPC: G03B27/32
Filed: 1980-06-16
Abstract: PURPOSE: To obtain the assigned conveying torque regardless of thickness of the material to be conveyed in such a way that pinch rollers are installed on the conveying belt and they can move upward and downward by rotation in response to the thickness of the material to be conveyed.  
     CONSTITUTION: Pinch rollers are constituted by providing arms 17 equipped with a roller 16 at one end rotatably in the arrow direction having the other end as the fulcrum at the upper part of a conveying belt 12 which is driven by a motor 11. The roller 16 usually contacts the belt 12 by its own weight, and turns freely with movement of the belt 12. When a relatively thick packing 10 is put on the belt 12, since the roller 16 turns with movement of the packing 10 clockwise to the arms 17, and gives its own weight on the packing 10, conveying torque of the packing 10 increases, and suppresses its slipping, so that the tip of the packing 10 can be easily inserted in the determined position of a printing mechanism 1.

Title: Liquid for electrolytic polishing of stainless steel
Inventor: YOSHIDA ICHIROU
IPC: C25F3/00
Filed: 1980-06-16
Abstract: PURPOSE: To accelerate the formation of an anodic film in the liquid for electrolytic polishing, reduce variations of the thickness of a plate and obtain excellent corrosion resistance and a mirror finished surface by adding a specified amount of basic nickel carbonate to orthophosphoric acid.  
     CONSTITUTION: Orthophosphoric acid added with 50W240g/l of basic nickel carbonate is used as the liquid for electrolytic polishing of stainless steel. When electrolytic polishing is conducted for about 20W60sec. by using said liquid, the nickel carbonate reacts with phosphoric acid, resultin in that only the nickel ion is left in the electrolytic solution and the remainder is removed as CO 2  gas. Accordingly, an excellent effect of electrolytic polishing can be obtained.

Title: Oil volume adjustor
Inventor: NOZAWA YUTAKA
IPC: F23N1/00
Filed: 1986-04-09
Abstract: PURPOSE:To simplify a structure of an oil passage extending from an oil chamber to a burner part without charging the oil passage within an oil amount adjusting main body at all by a method wherein a valve hole is made within a communication port between the oil chamber and an exit port. CONSTITUTION:A cylinder 13 is placed adjacent to an oil chamber 2 of a main body 1 of an oil amount adjustor and a valve hole 7 acting as a communication port is arranged between the oil chamber 2 and an exit port 6 as well as an oil passage. Normally, the valve hole 7 of a manual change-over valve mechanism MV is closed by a valve body 8 and fuel oil is supplied to a burner part B through an outlet pipe (an oil passage R1) of an electromagnetic pump SP. Under this condition, when a power failure occurs, a fuel supply in the oil passage R1 is stopped. However, when the valve body 8 is lifted up manually against a spring pressure of a pressing spring 10, the valve hole 7 is opened. Therefore, the fuel oil of flow rate from the oil chamber 2 controlled by an exit valve mechanism 5 flows into an oil passage R through the exit port 6 and is supplied to the burner part B, so that the fuel oil is not interrupted and the combustion of the fuel can be continued.

Title: Monolithic catalyst carrier for purifying exhaust gas
Inventor: MATSUMOTO SHINICHI
IPC: B01J23/86
Filed: 1986-04-09
Abstract: PURPOSE:To prevent the delamination of an activated alumina layer from a metal carrier base material, by enhancing the bonding strength of the activated alumina layer formed to the surface of the metal monolithic catalyst carrier base material and the metal carrier base material. CONSTITUTION:The composition of a catalyst carrier base material consists of 5-30% Cr, 1-10% Al, 0.01-0.5% of one or more of K etc. and the remainder Fe on a wt. basis. Because the ion radius of K or the like is larger than that of Al, K or the like is incorporated between lattices of activated alumina such as gamma, delta or theta-alumina having a large gap and the crystal structure thereof is stabilized. Therefore, when an alumina film is formed to the surface of the carrier base material by the heat-treatment of said base material, the transformation of activated carbon to alpha-alumina is suppressed and the precipitation of alpha-alumina is prevented. If a lanthanide element is added in an amount of 0.01-0.5wt%, perovskite type composite oxide is formed and purifying capacity is enhanced.
