Abstract: <P>PROBLEM TO BE SOLVED: To provide a technique for reducing the on-state resistance of a pin diode.  <P>SOLUTION: Trench slots 5 are formed on the surrounding of a pin junction composed of a first p-type diffusion layer 2a, an i layer 3, and an n-type high-density board 4. On the bottom of the trench slots 5, second p-type diffusion layers 2b which are not connected to the n-type high-density board 4 are formed. Bias is applied to the second p-type diffusion layers 2b to give them negative potential, which gives forward direction bais to holes coming in through the first p-type diffusion layer to make the holes attracted to the i layer 3. Meanwhile, the n-type high-density board 4 is made to have negative potential, which pushes electrons infused into the board 4 into the i layer 3. Thus, the overall carrier infusion volume in the pin diode 1 is increased to reduce its on-state resistance.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To reinforce tumble in a cylinder 2 without reducing opening rate of an intake port 5 excessively.  <P>SOLUTION: A bulkhead 11 is provided in the intake port 5 and is divided into a first flow passage 5A on an upper side and a second flow passage 5B on a lower side. An intake control valve 31 is arranged at a tip of a branch part 23, and a clearance 12 which becomes a communicating passage is formed between the bulkhead 11 and a valve element 33. When the intake control valve 31 is closed, a low pressure region occurs on the downstream side of the valve element 33, and suction air is taken in from a downstream side end in the second flow passage 5B due to difference in pressure, flows in the second flow passage 5B onto the upstream side, and is refluxed into the first flow passage 5A from the clearance 12. For this reason, flow rate of stream passing through the valve clearance on the lower side of the intake valve 7 is reduced, and flow rate of stream passing through the valve clearance on the upper side is increased to reinforce tumble. Since an inclination angle α of the valve element 33 at a close position is small and 30 to 40 degrees, variation of tumble strength for dimensional error of the clearance 12 is small.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
