Title: Control device for internal combustion engine
Inventor: OGAWA MASARU
IPC: F02D43/00
Filed: 1991-10-24
Abstract: PURPOSE:To accurately control the air-fuel ratio of a mixture supplied to an internal combustion engine provided with an exhaust gas recirculation system at a desired value. CONSTITUTION:An EGR direct rate EA (the rate of gas directly sucked into the combustion chamber out of the recirculation gas passed through a recirculation gas control valve (EGR valve) and an EGR carry-away rate EB (the rate of gas sucked into the combustion chamber out of the recirculation gas stagnated between the EGR valve and the combustion chamber) are calculated (S 41-S 51). The direct rate EA and the carry-away rate EB are calculated in response to the engine speed NE(tau) detected before a specified TDC(tau) and an engine load factor PBA(tau), using the maps set individually for the opening state (S42, SEcal=1) of the EGR valve, the time of shifting of the valve from the closed state to the opened state (S41, SEcal=O), the time of shifting of the valve from the opened state to the closed state (S43, SEcal=2). The circulation gas quantity (gin) actually sucked into the combustion chamber is calculated using the EA, EB, and a basic fuel quantity TIM is calculated based on the (gin).

Title: Choke coil and rectifying/smoothing circuit using the same
Inventor: ASADA KAZUHIKO
IPC: H01F17/06
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To increase an inductance value in a small current region compared with that in a large current region, by arranging on part of a magnetic path a low saturation magnetic flux portion whose saturation magnetic flux density is smaller than a core. SOLUTION: A rectifying/smoothing circuit 31 comprises a bridge type rectifying circuit 12, a choke coil 13 and a smoothing capacitor 14. The coil 13 has a winding 18 wound around a core 17 that is formed by laminating silicon steel plates, and also has a low saturation magnetic flux portion 20 along a magnetic path of magnetic fluxes 19 that are generated when a current flows through the winding 18. The portion 20 is made of ferrite, and its saturation magnetic flux density is lower than that of the core 17. The portion 20 has the same cross-sectional area as the magnetic path, but when the winding current is increased, the portion 20 magnetically saturates first, causing the magnetic resistance of the magnetic path to increase.  As a result, an inductance value in a low current region is increased compared with that in a large current region, and hence the shape, weight and cost can be suppressed.

Title: Heat-treatment method and device
Inventor: MATSUSHIMA MASARU
IPC: H01L21/26
Filed: 1994-12-09
Abstract: PURPOSE: To enable the wafer temperature to be controlled with high precision even in the quick start time by a method wherein a wafer is heated with a specific output at the heating start time while the temperature control is started when the measured values of a radiation thermometer over the control start setting temperature exceeds specific times. CONSTITUTION: A wafer 3 is heated at with specific output after the heating start, the temperature measured value exceeds 800 deg.C due to the transmission of light emitted by lamps 4 since the wafer 3 at the room temperature is transparent to the measured wavelength of a radiation thermometer 6. After starting the heating step, when the actual temperature of the wafer 3 exceeds 350 deg.C, the wafer 3 becomes opaque to the measured wavelength. Therefore, the temperature value measured by the radiation thermometer 6 lowers to 500 deg.C. When the actual temperature exceeds 500 deg.C, it coincides with the values measured by the radiation thermometer 6. Accordingly, by setting up the control starting temperature at 505 deg.C, when the value measured by said thermometer 6 exceeds two times, the control start timing can be confirmed by detecting it using a personal computer 7.
