Title: Internal combustion engine
Inventor: TANAKA KOTARO
IPC: F02B25/04
Filed: 1991-04-15
Abstract: PURPOSE:To prevent air-fuel mixture from blowing by when an intake valve and an exhaust valve are overlapped with each other and reduce a residual gas amount in a cylinder. CONSTITUTION:There is provided a recessed part 8 which constitutes a combustion chamber 5 on the intake side at the bottom surface 3a of a cylinder head 3, an intake valve 1 which is driven to open/close in the operational direction of a piston 4 is disposed at the recessed part 8, and an exhaust valve 2 is provided at the bottom surface 3a. Air which is discharged from a supercharger 10 is supercharged in a cylinder 12 from an intake port 16 and a scavenge port 14. The intake port 16 is formed toward the axis line 1a of the intake valve 1. Residual gas is pushed out with air which is introduced from the scavenge port 14, and mixture is introduced from the intake valve 1 side. The introduced mixture is hard to blow by due to the wall surface 8b of the recessed part 8, and also pushes residual gas to the scavenge port 14 side to discharge it with the air. It is thus possible to improve emission and so forth, and reduce fuel consumption.

Title: Short-circuiting structure for thyristor
Inventor: OOTSUBO YOSHINOBU
IPC: H01L29/08
Filed: 1984-04-25
Abstract: PURPOSE:To improve controllability of and ensure uniformity in short-circuiting resistance and thereby facilitate the manufacturing elements by a method whereing short- circuiting holes are extensively distributed to position themselves at the crossings in a uniform-density network irrespective of the arrangement of the multiplicity of sectors constituting a three-terminal thyristor equipped with an automatic arc-suppression feature. CONSTITUTION:Between an N type medium resistance region layer 8 and anode electrode 9, a P type low resistance region layer 3 is positioned to constitute a P-N junction with the N type medium resistance region layer 8. N type short-circuiting holes are so distributed that uniformity may be ensured in the size of short-circuiting resistance per unit area between the N type medium resistance region layer 8 and the anode electrode 9. At least the portion in contact with the anode electroe 9 is constituted of an N type resistance region 12 to prevent the contact resistance there from being excessively high. The short-circuiting holes are distributed to be positioned at crossings in a uniform-density network constructed of right triangles, squares, or others. The hole dimensions and the distance D are changed to control the size of short-circuiting resistance per unit area and a higher-density arrangement of short-circuiting regions ensures uniformity in short-circuiting resistance per unit area, all of which contribute to the improvement of element characteristics.
