Title: Electric field effect transistor and its manufacture
Inventor: NAKAJIMA SHIGERU
IPC: H01L29/80
Filed: 1988-07-07
Abstract: PURPOSE:To decrease parasitic capacity and improve high frequency characteristics of an element by providing spaces between a substrate and eaves that the upper parts of a gate electrode are expanding in eaves shape in the longitudinal direction of the gate. CONSTITUTION:Spaces 26a and 26b are provided between eaves 25a and 25b and a substrate 10. That is, since an insulating film 22 right below a gate electrode 25 is made in multilayer structure, spaces can be created between the eaves 25a and 25b of the gate electrode and the substrate 10 simply by removing a part of layers of the multilayer insulating film 22 by selective etching. Hereby, parasitic capacity decreases as compared with that when an insulating film is interposed, and high frequency characteristics can be improved.

Filed: 1994-07-21
Abstract: PURPOSE:To reduce a difference in temperature in an upper part and a lower part of a diffuser by providing in each diffuser ejection nozzles for ejecting pressurized air passed into the diffuser toward the fluidized-bed material and on the upper side of the ceiling of the diffuser a hollow part where the fluidized- bed material may stand. CONSTITUTION:The ceiling plate 3b which covers the upper side of a diffuser 3a, apart from the longitudinal middle and the end parts at the right and the left, is formed as a hollow part 24 in cutaway section. When the fluidized-bed boiler is in operation, pressurized air is passed from an air intake port into the diffuser 3a and ejected into the fluidized-bed boiler from an ejection hole 16a in each of ejection nozzles 16 so as to fluidize the bed material 4 to form a fluidized bed. On the other hand, even during the operation of the fluidized-bed boiler the bed material 4 which is left out of the fluidization stands in the hollow part 26 of the ceiling plate 3b of the diffuser 3a. Therefore, even after rise of the temperature inside the fluidized-bed boiler to high points through combustion of the fuel, the bed material 4 standing in the hollow part 24 bars the heat from transmission to, in other words, from directly heating the upper side of the diffuser 3a.

Title: Production of smectic liquid crystal device
Inventor: HARADA TAKAMASA
IPC: G02F1/133
Filed: 1985-08-01
Abstract: PURPOSE:To decrease the number of dislocations of the liquid crystal material packed in a panel as far as possible by injecting the liquid crystal material into the panel then reheating up the liquid crystal material up to the smectic A phase then subjecting the same to slow cooling. CONSTITUTION:The liquid crystal material in the cell takes the smectic C phase while forming domains in the process when the liquid crystal material changes from the liquid phase to the smectic A phase if the liquid crystal material is slowly cooled by natural cooling after the liquid crystal cell is constituted by filling said material into the cell. An injection port 3 is hermetically closed by a sealing material to com plete the liquid crystal panel upon thorough cooling of the liquid crystal material injected into the panel. Such liquid crystal panel is contained into a thermostatic chamber and is again heated until the liquid crystal material packed into the cell attains the smectic A phase. The heating of the liquid crystal panel is stopped at the point of the time when all the liquid crystal molecules are arrayed in the smectic A phase. If the crystal panel is gradually cooled to the temp. at which the smectic phase is attained in succession thereto, the liquid crystal molecules in the panel begin to simultaneously tilt so as to have an angle theta with the normal of the layer and the liquid crystal molecules in the liquid crystal panel change to the smectic C phase. The dislocations generated in the stage of injection are mostly annihilated.

Title: Electric wave altimeter
Inventor: KATAUE KOICHI
IPC: G01S13/04
Filed: 1992-06-05
Abstract: PURPOSE:To make low altitude flight not including unnecessary margin with automatic flight in the sky over sea by automatically distinguishing whether the electric wave reflecting surface is on land or sea through utilization of the fact that the change rate of the diffusion coefficient due to incident angle differs between on the land and the sea. CONSTITUTION:Degree of amplification proportional to the square of the altitude is given by a variable gain amplifier 1 to a reception signal of an electric wave beam Btheta0 radiated by an electric wave altitude meter right under in vertical direction, and the amount of attenuation dependent upon the altitude is corrected. Therefore, variation of the received power level P depends only on the diffusion coefficient sigma. This is detected 3, and the time mean of the data is determined by an averaging device 5, and variation of the coefficient sigma due to the shape of the land is removed, and entry is made by a subtractor 7. This procedure is also made with a reception signal of the electric wave beam BthetaA emitted at an incident angle thetaA, and the subtractor 7 determines the output ratio of averaging devices 5, 6. This ratio is equal to a value corresponding to the difference in the case it is turned into logarithm. The resultant is compared by a comparator 8 with the set threshold; if within the threshold, it is distinguished that the craft is flying in the sky over land, and if exceeding the threshold, distinguished as flying over the sea.

Filed: 1985-08-05
Abstract: PURPOSE:To implement a blue light emitting element having excellent characteristics, by using a GaAs crystal, to which In is added, thereby growing a high quality ZnSe epitaxial single crystal thin film. CONSTITUTION:The grating constant of ZnSe is 5.6676-5.6687Angstrom at a room temperature. Meanwhile, that of GaAs of a III-V group semiconductor is 5.653Angstrom , and that of InAs is 6.058Angstrom . The GaAs and the InAs have a so-called homogeneous fusing form, which is capable of single crystallization at any rate. Therefore, the grating constant can take values between 5.653Angstrom  and 6.058Angstrom  depending on the rate between Ga and In. The crystals of In0.034Ga0.966As and In0.04Ga0.96As are used for a substrate, and a ZnSe single crystal thin film is epitaxially grown. As a result, the gratings are aligned and no dislocation is found in the substrate. Therefore the excellent thin film, whose crystal defect is very few, is obtained. In this way, a P-N junction is formed in the ZnSe epitaxial film, and the excellent light emitting element is obtained.
