Abstract: In a combustion control apparatus of a direct-injection diesel engine, in which a fuel is injected at an early timing with an EGR ratio more than a first predetermined value at pre-mixed combustion area (H) where an engine load is relatively low so as to provide a pre-mixed combustion mode, while a diesel combustion mode is provided with the EGR ratio less than a second predetermined value at diffusion combustion area (D), when the operation of the engine 1 transfers from one of the pre-mixed combustion area (H) and the diffusion combustion area (D) to the other thereof, an opening of the an EGR valve 35 is changed and thereby a fuel injection mode is changed after an actual EGR ratio: EGR becomes a predetermined value: EGR1. When the EGR ratio: EGR is within a certain range (SB5→SB13→SB15), a follow-up injection (latter-injection) is executed (SB15, SB7) so that combustion thereby may begin at the timing when the main-combustion beginning at around TDC completes mostly.

Abstract: A balancer shaft apparatus efficiently prevent oil from being stirred in the oil pan and from being splashed into the cylinder block during the balancer-shaft rotation. Oil in a housing of the balancer shaft is discharged from a drainage hole formed at such a location above an oil level as to contact a base serving as a bearing beam of a crankshaft supporting member. The discharged oil hits inner surfaces of a recess formed on the lower portion of the crankshaft supporting member to form oil drops, returning to an oil pan. The housing is provided with guide passages connecting the drainage holes to a space in which the balancer shaft is disposed for draining the oil. These guide passages are formed with tapered guide surfaces for orienting the oil towards the lower portions of the crankshaft supporting member while splashed oil caused by the balancer-shaft rotation is drained through the drainage holes.

Abstract: Discharged stencils stored in a discharged stencil box of a stencil printer are compressed by a compression member driven by a DC compression motor. The cycle rate of pulses generated from a rotary encoder representing the speed of the compression motor is detected and the compression motor is stopped when the cycle rate of the pulses generated from the rotary encoder becomes equal to a value corresponding to a predetermined desired output torque of the compression motor.

Abstract: An exhaust purifying system includes switching between a stratified combustion state at a stratified combustion region (I) of low revolutions speeds and low loads and a homogeneous combustion state of substantially the theoretical air/fuel ratio at a warm &lgr;=1 region (II) adjacent thereto with higher revolution speeds or loads, wherein a first oxygen concentration sensor is arranged upstream from the three-way catalyst, and when an engine shifts from the stratified combustion region (I) to the warm &lgr;=1 region (II), the feedback control of the air/fuel ratio based on an output signal of that sensor begins, and the target air/fuel ratio A/F is set to a range of 14.0≦A/F<14.7, so that the target air/fuel ratio A/E is slightly richer than the theoretical air/fuel ratio, thus preventing a temporary deterioration of the exhaust gas state.

A nitride sidewall is formed to cover at least the side faces of an insulator cap and the upper electrode. A pad oxide film is formed to cover at least part of the side faces of the lower electrode and part of the upper surface of a semiconductor substrate. Since a second nitride sidewall is formed to cover the first nitride sidewall and the pad oxide film, a self-aligned contact hole can be formed by etching. As a result, a semiconductor device with a highly reliable self-aligned contact can be obtained.
