Patent JP-S60101974-A (JP)
Title: Semiconductor device
Inventor: NAKAGAWA AKIO
IPC: H01L29/80
Filed: 1983-11-08
Abstract: PURPOSE:To enable operation having a high direct current amplification factor while keeping low ON resistance by forming hetero structure inhibiting carrier injection from a gate layer on the source layer side in vertical type FET structure. CONSTITUTION:An n<-> GaAs layer 221 having high resistance is grown on an n<+> GaAs substrate 21 as a drain. A p<+> GaAs gate layer 23 is formed in a latticed shape, and an n<-> GaAs layer 222 having high resistance is grown on the layer 23. An n<-> GaAlAs layer 24 having high resistance is grown, and an n<+> GaAlAs layer 25 as a source is formed on the surface of the layer 24. A hetero-junction is shaped in the vicinity of the layer 25 because the forbidden band width of GaAlAs is made larger than that of GaAs in the element. That is, the height of a potential barrier to hole injection to the source from a gate is made larger than that of a potential barrier to electron injection to the gate from the source. Accordingly, operation having a high direct current amplification factor is enabled while keeping low ON resistance.

Title: Method and device of preventing occurrence of heat damage by means of metallic gasket
Inventor: YOSHINO NOBUO
IPC: F16J15/08
Filed: 1984-10-05
Abstract: PURPOSE:To decrease a thermal conduction amount, by a method wherein a gromet part, located to an end part on the heat source side, is formed thicker than a bead part spaced away from the gromet so that the pressure of a contact surface to a joint is increased. CONSTITUTION:A metallic gasket 30 is located between a head joint 22 of a cylinder head 6 and a flange joint 26 of a mounting flange 24, and is compressed through the tightening force of a bolt. Thicknesses T1 of a first gromet part 42 on the periphery of a port hole part 40 and a second gromet part 48 on the periphery of a bolt hole part 46 are increased by a thickness, equal to a gap Tc, over a thickness T2 of a central portion between the first gromet part 42 and the second gromet part 48. Thus, compared with a conventional gasket, enables a contact area to be decreased over the area of the flange joint 26, permits isolation of heat from an exhaust manifold 18, decreases a thermal conduction amount, and prevents increase of the temperature of the cylinder head 6.
