Title: Preparation of olefins from heavy oils
Inventor: SUGIYAMA HIROSHI
IPC: C10G9/32
Filed: 1977-11-14
Abstract: PURPOSE: To obtain olefins in high yeilds and to recycle and reuse heating medium particles of calcium sulfate under complete treating conditions of heavy oils in the thermal cracking process.  
     CONSTITUTION: Raw materials comprising heavy oils and/or finely pulverized coal are fed to a reactor wherein heating medium particles containing calcium sulfate heated at 700W900°C, and converted to gases and coke. The calcium sulfate is converted to calcium sulfide, and the heating medium particles having deposited carbon are transferred to a regenerator, where the coke is burned in the presence of an excess of O 2  at 750W1200°C to convert calcium sulfide to calcium sulfate. The calcium sulfate is recycled to the reactor. H 2 ,CO, and methane in the produced gas react with CaSO 4  as shown in the reaction formulas to consume H 2 , thus suppressing the hydrogenation of olefins.

IPC: B25J19/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To apply a sealing agent on a small radius curved part using an industrial robot. SOLUTION: In this device, one end part of a bracket 26 is attached to a working end 23 of the hexaxial industrial robot 22 and a sealing gun 31 is attached to the other end part of the bracket 26.

Title: Apparatus for molding monolithically lens and mirror frame
Inventor: NII TAMOTSU
IPC: B29L12/00
Filed: 1984-07-03
Abstract: PURPOSE:To allow a restricting member for a lens not to touch directly with the lens surface so that the shock or the like would not be transmitted when molds are opened or closed, to avoid the risk of occurrence of cracking or the like of the lens, and make it possible to carry out centering in a short period of time, by providing means for holding the lens preliminarily, and forming a small clearance to such a degree that does not allow a resin for forming a mirror frame to flow between the holding means and the lens. CONSTITUTION:A lens 5 is placed on a core 7. When suction is applied by a sucking apparatus 6, since a rubber 7b is in firm contact with the lens 5, the inside of the core 7 is made vacuum thereby the lens 5 is attracted by the core 7. Since the lens 5 is clamped by a slide core 1, the lens 5 is centered and is lifted a little from a restricting core 7 so that a clearance may be formed to such a degree that wound not allow a resin to flow in. Thus, only by placing a lens on a diameter restricting core for the lens, the centering can be automatically done quickly, and the diameter restricting core is kept to have a little clearance between it and the lens and does not touch directly with the lens surface.
