IPC: G06T1/00
Filed: 1986-02-07
Abstract: PURPOSE:To reduce a measuring time and a processing time, by finding a data on the other side executing a complex conjugate arithmetic after Fourier- transforming only one side of a pair of nuclear magnetic resonance signals against a time, and afterwards, performing a Fourier transform regarding to a phase encoding quantity. CONSTITUTION:The data on the other side of each pair of the nuclear magnetic resonance signals is calculated by performing the complex conjugate arithmetic operation, after the one side of each pair of previous stated nuclear magnetic resonance signal having the same absolute value and the phase encoding quantity with a reverse sign, is received, and a received nuclear magnetic resonance signal is Fourier-transformed against the time, and each of data is Fourier- transformed against the phase encoding quantity. In this way, the number of steps of arithmetic operations is reduced under the condition where the number of the steps of phase encoding is reduced by half, and it is possible to reduce the measuring time, and a signal processing time of the nuclear magnetic resonance signal.

Abstract: PURPOSE:To secure the insulating performance between a first layer and a second layer by a method wherein, after phosphorus or boron has been implanted selectively into an insulating film on a wiring metal, the insulating film flows by a heat treatment so that a flow shape in a low region inside a wafer cannot be spoiled. CONSTITUTION:An insulating film (I) 2 such as a thermal oxide film, PSG, BPSG or the like is deposited on a P-type single-crystal silicon substrate 1; a wiring operation is executed by doped polysilicon or the like. After that, an insulating film (II) 3 such as a thermal oxide film, a silicon nitride film or the like is deposited; a wiring operation of a second layer is executed by using a wiring metal (I) 4 of doped polysilicon or a silicide. After that, an insulating film (III) 5 such as PSG, BPSG or the like is deposited. A resist 6 is left only in a high region inside a wafer by a photolithographic method. After that, an ion of phosphorus or boron is implanted; the resist is removed; the insulating film (III) 5 flows under a dry or pyro condition. During this operation, a phosphorus concentration value or a boron concentration value in a region where the ion has been implanted is high; accordingly, it is easy to flow as compared with a region where the ion has not been implanted.

Title: Tape cartridge
Inventor: SATO AKIHIKO
IPC: G11B23/087
Filed: 1988-02-03
Abstract: PURPOSE:To make a tape guide part superior in abrasion resistance by forming it out of thermosetting resin. CONSTITUTION:In a main body case 1, the tape guide part 10 to be brought into sliding contact with the back side of a tape 3 is formed out of thermosetting resin. For this thermosetting resin, phenol resin is preferable in its superior point than, e.g., epoxy resin, etc., in the injection molding properties. In addition, it is more preferable to use glass fibered phenol resin rather than phenol resin itself alone, because of promoting tensile and flexural strengths and thermal deformation temperature and reducing molding shrinkage. The tape guide part 10 made of thermosetting resin is strong in hardness, and even when a back- coated tape 3 is traveled at high speed, the degree of abrasion due to slide contact with this tape is very much reduced, while abrasion dust is not generated.
