Title: Intake control device for internal combustion engine
Inventor: SAIKI TOSHISHIGE
IPC: F02D41/04
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in a function due to deterioration of a catalyst, by reducing a torque shock at controlling time, in an internal combustion engine having an intake control valve and an NOx adsorptive decomposition catalyst. SOLUTION: An intake control valve 19, opened/closed by an actuator 20, is provided in an intake passage 2 between a surge tank 9 in the downstream of a throttle valve 8 and an injector 4, and a NOx absorptive decomposition catalyst 31 is provided in the halfway of an exhaust passage 7. In an electronic control device (ECU) 41, when an air-fuel ratio lean condition is long continued, since an absorbed NOx amount leads to a saturation condition, air-fuel ratio is substantially increased from a lean condition up to this time, and release of NOx is performed. In the case of increasing of the concerned air-fuel ratio, the ECU41 shortens an opening time of the intake control valve 19.  Consequently, even without increasing a fuel injection amount, the actual air-fuel ratio is placed in a condition richer than before, and rapid increase of an output by rapidly increasing a fuel injection amount is suppressed. Also necessity for performing delay control of ignition timing is eliminated.

Title: Semiconductor memory device
Inventor: MINATO OSAMU
IPC: H01L27/11
Filed: 1985-12-27
Abstract: PURPOSE:To make a sense amplifier high-speed and low-power consumption one so as to obtain a large-scale static memory device, by using a circuit which is formed by combining a pair of bipolar transistors and plural MOS transistors with a sense amplifier circuit. CONSTITUTION:The electric current conducing to a bipolar transistor 301 is conducted through MOA transistors 303, 306, and 313 and biases the gate of an MOS transistor 314 to a prescribed voltage. At the time of biasing, the electric current conducting to the transistor 301 is larger than that conducting to another transistor 302 and the voltage at an output terminal 311 drops to almost OV. On the other hand, at another system constituted of MOS transistors 308, 315, 305, and 312, the completely opposite operations are carried out and the voltage at an output terminal rises to a sufficiently high level. Since a very small potential difference is inputted to the bipolar transistor, the capacity for driving the MOS transistors at the later stages is large and the large load capacity of this amplifier itself is not added to a common data line. Therefore, a high speed and high amplification factor can be obtained by the combination of bipolar transistors and MOS transistors.

Abstract: PROBLEM TO BE SOLVED: To improve the stability in polishing rate by measuring the concentration of oxidant in the abrasive slurry to be supplied to a polishing device, and controlling the same to constantly keep the concentration within a proper range. SOLUTION: A tungsten film formed on a silicon wafer is used as a substance to be polished, and the polishing is executed by using the abrasive slurry including hydrogen peroxide. The concentration of hydrogen peroxide in the abrasive slurry stored in a slurry supply unit 18 is sampled by a concentration meter 32 after the polishing is started by a CMP device body 12. When the concentration of hydrogen peroxide in the abrasive slurry is lower than a threshold value, a necessary amount of hydrogen peroxide is added to the abrasive slurry stored in the slurry supply unit 18. The hydrogen peroxide is added by a hydrogen peroxide supply unit 34 and a flow adjusting unit 36 under the control by a controller. Whereby the polishing work can be continuously performed for a long time in a stable state without largely changing the polishing rate.
