Title: Oil warning device for ship engine
Inventor: KOIKE TAKASHI
IPC: F02P11/02
Filed: 1983-10-15
Abstract: PURPOSE:To prevent an engine from suddenly rotating at a high speed, when oil is added, by detecting the lower limit of oil, making an oil level switch self holding in this state, and allowing said engine to maintain a low speed rotation. CONSTITUTION:When an engine has overheated causing a temperature sensing switch 44 to close, the ratio of duty of the output Va of an oscillation circuit 94 is gradually increased while a buzzer 46 is operated, to prolong the misfiring time of a spark plug 36, allowing the engine to rotate at a constant low speed. Also, when the oil in a tank 56 reaches the lower-limit level, a point of contact 62a is closed, a red lamp 54 is lit and the buzzer 46 is operated, allowing this condition to be preserved by means of a self-holding circuit. At the same time, a low-speed maintenance circuit 80 is operated an in the case of overheating. Thereby, sudden acceleration of ship due to sudden increase in engine rotation can safely be prevented even when oil is added. After oil is added, when the engine is restarted after a main switch 42 is once turned off, normal operation is resumed.

Title: Method for recovering vapor of organic solvent
Inventor: INOUE KENICHI
IPC: B01D53/22
Filed: 1989-07-25
Abstract: PURPOSE:To achieve a high recovery of organic solvents by making concentrations of uncondensed organic solvents in the cooling and condensing processes of concentrated gases higher than those of organic solvents which have not passed through a membrane module to return said uncondensed gases to the supply side of mixed gases. CONSTITUTION:Mixed gases containing organic solvent vapor are supplied to a permselective membrane module 1 for permeation and condensation, whereby the concentrated gases are cooled and condensed by means of a condenser 5 to recover organic solvents in a liquid phase, which are sent to a condensed liquid recovery tank 9. And the concentrations of organic solvents which have not been condensed in said cooling and condensing processes are made higher than those of organic solvents which have not passed through the membrane module 1, while said uncondensed liquids are returned to the supply side of the mixed gas through a return pipe 10 and the gases which have not passed through the mule 1 are discharged through a discharge pipe 2. As a result, organic solvents can be recovered from gases containing organic solvent vapor at a high recovery rate, thereby reducing concentrations of organic solvents in gases vented to atmosphere.

IPC: F16C33/64
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To improve the rolling fatigue life of a ball bearing race by having sufficient reliability even against the severity of a service environment due to the tendency of the lighter weight and lower fuel consumption of an automobile. SOLUTION: In the case of manufacturing a thrust type ball bearing race having a ball bearing groove, a bearing race body 1 is formed through plastic processing together with the ball bearing groove so that the longitudinal metal flow F of steel raw material may have a direction perpendicular to the direction of thrust load.
