Title: Corrosion preventing method of tower top condensing apparatus of evacuated distillation tower
Inventor: HOSAKA FUMITAKA
IPC: C10G7/10
Filed: 1979-09-29
Abstract: PURPOSE: To effectively prevent the corrosion in a condensing apparatus having multiple stages of condensers, in said condensing unit, by circulating part of the collected condensed water to the condensers.  
     CONSTITUTION: Since a neutralizing corrosion preventing agent is injected into the fluid at the inlet of the 1st stage condenser 3, it is virtually ineffective in the 2nd and subsequent stage condensers for the condenstion of the top gas of a evacuated distillation tower 1. Thereupon, in order to utilize the corrosion preventing agent entered the condensed water of the 1st stage for the 2nd and subsequent stages, part of the condensed water collected in a receiving tank 8 is recirculated to the 2nd and subsequent condensers. For example, the condensed water of around 6.5pH in which a relatively large amount of the corrosion preventing agent exists in the receiving tank 8 is circulated to the condensers 5, 7 by way of a pump 9, discharge piping 12 and circulating piping 11. Since this causes not only the pH in the water in the condensers to be increased but also the corrosion preventing agent to be introduced therein, it acts extremely effectively for prevention of corrosion.

Title: Production of deformed sintered parts
Inventor: YOSHIHARA OSAMU
IPC: B22F3/24
Filed: 1978-10-11
Abstract: PURPOSE: To improve the accuracy of the parallelism and squareness of end faces by beforehand forming low protrusions to the portions corresponding to the end faces of the part at the molding of raw material powder and compressing the protrusions at the sizing after sintering at the time of producing the deformed sintered parts.  
     CONSTITUTION: At the time of molding a cam 1 which has a deformed shape being not axis-symmetrical in shape by powder metal raw material 1, low protrusions 5, 6 of circular form are formed concentrically to the circumferenial edge of a cam shaft fitting hole 4 in the portions corresponding to the top and bottom end faces 2, 3 of the cam 1. The height h 1  of the protrusions 5, 6 is made not less than 0.1mm and 10% or less of the thickness H of the cam 1. After this molding is sintered, it is pressed from the top and bottom directions by pressing in the sizing process, whereby the protrusions 5, 6 are preferentially compressed and the height is reduced down to h 2  which gives no hindrance in use. The squareness to the fitting hole 4 and the parallelism of both end faces are formed readily with high accuracy.

Abstract: PURPOSE:To make a computer simulate robot operation control, which is performed by the robot controller, with high precision. CONSTITUTION:This robot controller 10 is connected to the computer 30 such as a work station. The robot controller 10 is composed principally of a processor and controls robot operation according to basic software and a robot program. The command signal of the robot operation control is sent originally to the robot, but transferred to the computer 30 through a communication means 20 here. The computer 30 simulates the robot operation according to the command signal and the simulation is displayed on the display 36 of the computer 30. The robot operation can, therefore, be simulated without transplanting operation from the robot controller 10 to the computer 30 which requires much labor. Further, the simulation is based upon the command signal of the robot operation control that the robot controller 10 actually performs for the robot, so the simulation is high in precision.
