IPC: F16C33/10
Filed: 1993-10-15
Abstract: PURPOSE:To prevent flow of lubricating oil from deviating in radial direction by influence of centrifugal force accompanied rotation so as to solve the shortage of lubricating oil on the rear end side of a pad inner circumferential end, in a tilting pad thrust bearing.

Title: Mos logical circuit
Inventor: ARIMOTO AKIYA
IPC: H03K19/00
Filed: 1984-12-05
Abstract: PURPOSE:To suppress the current flowing to an MOSTr by changing the gate potential of the MOSTr which raises or drops the node potential in response to said node potential. CONSTITUTION:The potential of a node 7 is set at an H level when a logical output circuit 8 is kept off or at an H level. Then a P type MOSTr9 is cut off and no current flows to resistances 13 and 14. Thus the potential of a gate 2 of a P type MOSTr1 which raises the potential level of the node 7 is set at the same level of a negative potential 6. Then the potential of the node 7 is raised by a resistance component between a source 3 and a drain 4 of a Tr1. The Tr9 conducts when the circuit 8 is set at an L level, and the potential of the gate 2 rises up by an amount equal to the drop amount of voltage of the resistance 14. Thus the current flowing to the Tr1 is reduced. In this case, the gate potential of the Tr1 does not rise up to a cut-off level owing to the resistance 13. Then the raising action of the potential is not stopped. Thus the load of the circuit 8 can be reduced.

Title: Start control device for internal combustion engine and fuel property decision device
Inventor: SUZUKI NAOTO
IPC: B60W20/00
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To ensure the excellent start performance regardless of fuel properties and also prevent the wrong decision of the fuel properties. SOLUTION: When the starting condition of an internal combustion engine is realized, an usual start control is carried out to start the internal combustion engine. After the start of the internal combustion engine is started by the usual start control, when the start is finished in a prescribed time, it is judged that the properties of the fuel supplied to the internal combustion engine is soft. On the other hand, when the start is not finished in the prescribed time, it is judged that the fuel properties are heavy. In this case, after elapsing the prescribed time, the start control for heavy fuel is carried out in place of the usual start control so that the start of the internal combustion engine is quickly finished.  By this method, the fuel properties are detected before the start of the internal combustion engine is finished and also when the fuel properties are heavy, the start control is changed to the control responding to the fuel properties.
