Title: Compound semiconductor device
Inventor: KANAMORI MIKIO
IPC: H01L29/47
Filed: 1989-04-27
Abstract: PURPOSE:To obtain a compound semiconductor device wherein a side gate effect is reduced, by providing a one-conductivity-type semiconductor region broader than a gate electrode, under the end part of the gate electrode. CONSTITUTION:At the time when N-type operation layers 3 and 4 are formed, operation layers, i.e., N-type regions 5a and 5b, are formed also in the peripheries of the fore-end parts of a gate electrode 2. While a drain current lowers and a leak current increases as a gate voltage increases at a negative potential (i.e., a side gate voltage), the side gate voltage whereat the drain current begins to decrease, and also a breakdown voltage of the leak current, is high. The operation layers (N-type regions) surrounding the fore-end parts of the gate electrode need only to be impurity layers whose resistance is lower than that of a semi-insulative substance. However, it is more effective for reducing a side gate effect that the concentration of impurities is higher and that the resistance is lower.

Title: Swaging machine for working wire rod with deformed cross-section
Inventor: YOSHIDA KEIICHIRO
IPC: B21C37/04
Filed: 1994-05-25
Abstract: PURPOSE:To enable wire rod to be formed without rotational force imparted to it by radially holding a die and hammer with a holder, fitting the holder inside a roller and fixing the holder in a swaging housing. CONSTITUTION:A die 18 and a hammer 19 are radially held in a holder. When a fly-wheel 6 rotates in the direction of the arrow 23, a roller 12 also revolves in the same direction while rotating in the direction of the arrow 24. When the roller 12 reaches the outer wall of the hammer 19, it rolls while pressurizing the hammer 19 in the direction of the arrow 25. Since the hammer 19 is bulged in a circular-arc shape, the hammer is pressurized in the direction of the arrow 25 by the bulginess, and the die 18 pushed by the hammer 19 is also moved in the same direction, press-forming the wire rod in accordance with the cavity of the die 18. Thus, the die 18 pressurizes the wire rod at a fixed position without rotating, providing the wire product with an accurate cross-section.
