Title: Motor controller and electric power steering device

IPC: H02P21/00
Filed: 2006-12-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor controller wherein abrupt fluctuation in motor current value can be suppressed and an electric power steering device.  <P>SOLUTION: In the electric power steering device 10, proportional-integral control is carried out by ECU 50 based on a current value Ij for determination obtained by subjecting the q-axis actual current value Iq of an assist motor 40 to lead-lag compensation. As a result, proportional-integral control based on a q-axis actual current value that underwent lead-lag compensation can be carried out. Therefore, response in control to fluctuation in q-axis actual current value can be accelerated as compared with cases where control is carried out based on a q-axis actual current value without lead-lag compensation. Therefore, it is possible to accelerate proportional-integral control to fluctuation in motor current value to suppress abrupt fluctuation in motor current value.  <P>COPYRIGHT: (C)2008,JPO&INPIT

IPC: C03C23/00
Filed: 2004-04-30
Abstract: The invention concerns alkaline glasses with modified glass surfaces. The technical object of the invention is to stabilize the modified glass surface so that reverse sodium diffusion out of the volume is substantially avoided even at elevated temperatures and in particular in the case of post-treatment procedures using a flame. Surprisingly it was found that a modified glass surface of an alkaline glass is substantially resistant to reverse sodium diffusion from the volume at elevated temperatures if the chemism within the surface has an aluminum concentration which is markedly increased in relation to the volume. The cause can be the very high level of negative formation enthalpy of albite phases. The process according to the invention is characterized in that the surface of said glasses is brought into contact with elevated levels of aluminum concentration and is subjected to a heat treatment.

Abstract: An improved tray ration heating system includes a reservoir. A heat exchanger transfers heat to the reservoir. A firebox at one end of the reservoir has an opening to receive a burner flame tube. The firebox delivers heated gasses from the burner flame tube along the underside of the reservoir to an opposite end of the reservoir. A main channel along the reservoir includes baffles which produce a tortuous path and introduce turbulence to the hot gasses. First and second channels adjacent to the main channel redirect hot air exiting the main channel, and third and fourth channels direct hot gasses exiting the first and second channels towards the opposite end of the reservoir. An exhaust channel extends along a vertical wall of the reservoir to an exhaust opening. The exhaust channel has baffles for displacing hot gasses across the vertical wall. An insulated outer liner supports the reservoir and heat exchanger.
