Title: Method and apparatus for controlling electric rolling stock
Inventor: YAMASHITA MICHIHIRO
IPC: B60L15/20
Filed: 2008-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To properly suppress the induction of slip or skid in another shaft that may occur when slip or slid occurs.  <P>SOLUTION: When slip or skid occurs, readhesion control is carried out on a first shaft that has slipped or skidded and slip/skid induction suppressing control is carried out on each of the other shafts, second to fourth shafts. In the slip/skid induction suppressing control, the torque of a shaft to be controlled is varied in synchronism with torque reduction by readhesion control. The amount of varied torque Δτ<SB>eb</SB>is determined based on acceleration α at the slip or slid of a slipping/skidding shaft and a predetermined coefficient k. The coefficient k is determined based on which, slip or skid, has occurred, the positional relation between the shaft to be controlled and the slipping/skidding shaft displaced in a vehicle, and the like. In case of slip during power running, for example, the amount of varied torque is determined to reduce torque when the shaft to be controlled is positioned behind the slipping/skidding shaft and increase torque when the shaft to be controlled is positioned ahead of the slipping/skidding shaft.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a hot water supply device for effectively suppressing loss of heat energy by heat conduction between an inflow-side joint and an outflow-side joint mounted on a joint mounting member of a heating unit.  <P>SOLUTION: Since a heat insulating section 72a for blocking heat conduction between the inflow-side joint 73 and the outflow-side joint 74 is disposed on a joint mounting plate 72 mounted on a unit body of the heating unit, the lowering of a temperature of the water for hot water supply of high temperature in outflow-side piping caused by the water for hot water supply of low temperature of the inflow-side piping, is prevented, and loss of heat energy is effectively suppressed. Here, as the heat insulating section 72a is formed by a slot 72b formed on the joint mounting plate 72, the heat insulating section 72a is formed with a simple structure, which is very advantageous to practical application.  <P>COPYRIGHT: (C)2010,JPO&INPIT
