Title: Semiconductor device
Inventor: SAWADA AKIYOSHI
IPC: H01L29/68
Filed: 1990-11-21
Abstract: PURPOSE:To enable one-dimensional active layer to be produced and achieve a transistor which can handle a high frequency region according to a low noise by controlling carriers which are distributed non-uniformly and are characteristics properties to cyclic recesses and projections. CONSTITUTION:After recesses and projections are provided on a semi-insulation GaAs substrate 17 due to a diffraction grid image of He-Cd laser for forming a wave form and then the substrate is washed, an electron accumulation layer 15 is formed on a hetero interface between AlXGa1-xAs layer 21 and GaAs layer 14 which are allowed to grow by the MOCVD method. In HEMT, since a two-dimensional electron is entrapped at an interface of AlGaAs/GaAs, fluctuation from a classic electron stream line becomes only two-dimensional within a surface of the hetero surface. When a noise in three-dimensional directions is set to 1, that in two-dimensional directions becomes 2/3. By using a two-dimensional channel for an active layer, heat-build-up due to scattering of electrons can be suppressed and noise can greatly be reduced in the HEMT where degree of freedom of scattering of electrons is changed from three dimensions to two dimensions.

Inventor: MORISHIMA SHINGO
IPC: F02D41/14
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To always suitably retain a fuel injection quantity to an internal combustion engine even any engine operation condition. SOLUTION: An injector 18 is arranged in the intake port 17 of an internal combustion engine 1, and an intake pressure sensor 8 is arranged in an intake pipe 2. A CPU 33 in an ECU 30, variably sets a rate that injection fuel is stuck on the wall surface of an intake pipe, which is the parameter of a fuel behavior model, the remaining rate of stuck fuel, a ratio that injection fuel is stuck on the wall surface in a cylinder and the remaining rate of stuck fuel, while corresponding to an absolute value of intake pressure PM. Then, the CPU 33 corrects a fuel injection quantity by using each parameter. In this case, when the absolute value of intake pressure PM is set on a positive side (such as when a vehicle is accelerated), the rate that injection fuel is stuck on the wall surface of the intake pipe and the remaining rate in the cylinder are increased, and also the remaining rate of fuel stuck to the intake pipe and the rate that fuel injection is stuck on the wall surface in the cylinder are decreased, and when the absolute value of intake pressure PM is set on a negative side (such as when the vehicle is decelerated), the rate of fuel injection stuck on the wall surface of the intake pipe and the remaining rate in the cylinder are decreased, and also the remaining rate of fuel stuck to the intake pipe and the rate of fuel injection stuck on the wall surface in the cylinder are increased.

Title: Recording medium and its recording/reproducing method
Inventor: YASHIRO TSUTOMU
IPC: G11B5/02
Filed: 1992-10-30
Abstract: PURPOSE:To improve track density by providing a recording layer having thermal hysteresis, impressing a pulse voltage to the surface of the recording layer, and forming a large number of infinitesimal ferromagnetic phases on the recording layer by the heat energy. CONSTITUTION:The infinitesimal ferromagnetic phase 7 already magnetized in the direction perpendicular to the surface of the recording layer 3 is formed on a recording medium 1. The tip of a needle 5 is coincided with the position of the ferromagnetic phase 7, and a current is made to flow through a coil 8 in a direction opposite to the case that the medium is formed, then, magnetization can be inverted. In other words, an initial state corresponds to a state 0, and a magnetization inverted area corresponds to 1. Thereby, an information bit can be formed. When reproduction is performed, the information bit recorded on the ferromagnetic phase 7 is made to scan by the needle 5, and magnetic flux enters the needle 5 corresponding to the inversion of the magnetization of the information bit, and the direction of the current on the coil 8 can be detected by electromagnetic induction. Since the direction of a detection current is fluctuated by the direction of magnetization of the information bit, thereby, the information bit can be reproduced.
