Title: Multi-tube type heat transfer device
Inventor: KURITA KOICHI
IPC: F28D7/16
Filed: 1989-11-15
Abstract: PURPOSE:To prevent stay of fluid at a body side which tends to occur at the center of a multi-tube type heat transfer device and to suppress a temperature difference in the radial direction of the fluid at the body side by providing a cylinder disposed parallel to a heat transfer tube closed at both ends at the center of the device. CONSTITUTION:A plurality of dummy tubes 9 parallel to a heat transfer tube 9 having the same outer diameter as that of a heat transfer tube 1 are arranged at the center of a reactor body 11. The tubes 9 are supported by deflectors of upper and lower ends #2 to #6, and blind plates 12, 12, are provided at both lower and upper ends of the tube 9. A passage area of the center is so increased as not to reduce flow rate in a body axial direction at the center, gradually decreased toward the periphery of an intermediate part to compensate pressure loss due to radial flow to make the axial flow rate distribution of the body substantially uniform. Since a hole is formed at the center of the deflector #1 of lowermost stage, the quantity of the fluid at the body side to be invaded to the center is increased. Since the fluid after the hole of the deflector #1 is again radially dispersed by the plate 12, the radial flow rate distribution can be made uniform.

Abstract: PURPOSE:To make it possible to obtain an non-alloy ohmic contact, by implanting magnesium iron within a specified range of implantation quantity in the forming process of ohmic contact on a P-type conductive layer. CONSTITUTION:In the forming process of ohmic contact on a P-type conductive layer, magnesium ion is implanted within a range of implantation quantity 3-5X10<15>cm<-2>, and then annealing is performed for a short time. In a case where the implantation quantity is changed in the following four kinds; namely, 1X10<15>, 3X10<15>, 5X10<15> and 7X10<15>cm<-2>, the positive hole density distribution of samples of 1X10<15> and 3X10<15>cm<-2> shows the remarkable increase of peak positive hole density in accordance with the increase of implantation quantity. In the case where the implantation quantity increases up to 5X10<15>cm<-2>, the peak positive hole density little increases as compared with the case of implantation quantity 3X10<15>cm<-2>, and it is made obvious that the increase of peak density of positive hole in accordance with the increase of implantation quantity has a saturation tendency. Thus, the formation of a P-type ohmic contact having a low contact resistance of non-alloy is enabled.
