Title: Manufacture of metal oxide semiconductor field-effect transistor
Inventor: KANAMORI SHIYUUJI
IPC: H01L29/78
Filed: 1981-02-06
Abstract: PURPOSE:To reduce the scattering of channel length, and to improve the yield of an element for high frequency by diffusing source and drain regions and reshaping a diffusion layer so as to extend to the channel region side while using a gate film on the channel region as a mask. CONSTITUTION:A gate oxide film 21 is shaped to a substrate such as a P<-> substrate 20, a mask material 22 is formed, the N type diffusion layers 23, 24 are molded to the source and drain regions, and punch-through voltage is measured. Consequently, a film such as the oxide film 21 is used as a mask material 22 and the side of the oxide film is etched for a fixed time when the channel length must be shortened. Ion implantation or diffusion treatment is conducted again while employing the oxide film 25 left as a mask, desired diffusion layers 26, 27 are shaped, and processes after the formation of electrodes are conducted. When the channel length may be adjusted minutely, heat treatment through which layers such as the diffusion layers 23, 24 are deepened is conducted at a predetermined temperature and for a fixed time after measuring. Accordingly, the characteristics of the element for high frequency having small feedback capacity are made uniform, and the element can be manufactured in high yield.

Title: Thallium group oxide superconductive wire-rod
Inventor: HOSONO FUMIKAZU
IPC: C01G1/00
Filed: 1990-01-26
Abstract: PURPOSE:To better the critical current density (Jc) characteristic of a thallium group oxide superconductive wire-rod in a magnetic field by utilizing as the core part of the superconductive wire-rod a superconductor formed through the process of heat- treating powdered bodies each comprising an oxide of Ca or of Ca-Cu compounded with the powder of a thallium group oxide superconductor. CONSTITUTION:As a superconductor forming the core part of a thallium group oxide superconductive wire-rod is utilized powder comprising an oxide of Ca or of Ca-Cu, as represented by CaO, Ca2CuO3, CaCu2O3 and the like, added to the powder of a thallium group superconductor. In this case, the mutual pinning force of superconductive grains becomes strong because each CaO or the like is dispersed minutely in its semi- melted condition and further trapped in each of superconductive crystal grains by the peritectic reaction thereof while functioning as a restraint from forming a different phase in the crystal grain boundary of the superconductor when the superconductive grains forming the core part are sintered and heat-treated respectively at a comparatively high temperature, e.g. a range from 900 to 920 deg.C in order to be combined together. This can better the critical current density (Jc) characteristic of the superconductive wire-rod in a magnetic field.

Title: Semiconductor laser device
Inventor: MURAKAMI TAKASHI
IPC: H01S5/00
Filed: 1983-02-02
Abstract: PURPOSE:To obtain a laser, characteristics thereof are excellent and reliability thereto is superior, by suppressing a surface morphology with a terraced stepped difference by inclining a main surface only by a specific angle while using a waveguide direction as an axis, growing a thin uniform active layer and preventing the displacement of the direction of emitting beams by controlling the direction of inclination. CONSTITUTION:A main surface is inclined at an angle of 0.2-5 deg. while using the waveguide direction as an axis. For example, a face orientation of a substrate consisting of GaAs is inclined at 1 deg. from a 100 face. Since a thin uniform active layer 13 can be acquired by inclining the substrate, currents injected to the active layer 13 are equalized, and beams emitted by injection currents do not scatter and are emitted uniformly. Since the substrate 11 is inclined in the direction that is turned while using emitting beams as an axis, the direction of emitting beams is the same as conventional type devices through the substrate 11 is inclined, and no trouble is generated even when a laser chip is mounted to a package.

Title: Automatic phase correction circuit
Inventor: TAKAHASHI TADAO
IPC: H01Q3/38
Filed: 1990-01-25
Abstract: PURPOSE:To prevent mis-correction due to a measurement error of an automatic phase correction circuit by setting a threshold level at which correction of a feeding voltage for the automatic phase correction circuit is to be implemented or not while adding a quantized phase error of a phase shifter of a system corresponding to each radiation element to the threshold level respectively. CONSTITUTION:A threshold level for phase correction is stored in a RAM/ROM 15 while being added with a quantization phase error of each phase shifter corresponding to each system in advance. After the end of phase calculation by an APU 14 calculating the phase shift correction, the result is read by a CPU 8 via a bus line 16. When there is a deviation of a phase in excess of the threshold level, the correction data is written in a RAM 10 via an I/O 9 and a scanning timing generator 5 from the CPU 8. The operation above is implemented to all systems corresponding to radiation elements. At beam scanning, a phase shift code of a ROM 6 and a correction phase shift code of the RAM 10 are added by an adder 10 and the result is fed to each phase shifter. Thus, a stable beam directivity is obtained.

Filed: 1992-02-03
Abstract: PURPOSE:To obtain the piezoelectric resonator with small size and high performance by reducing the response of undesired resonance in the vicinity of the resonance frequency in the thickness longitudinal energy enclosing piezoelectric resonator. CONSTITUTION:An exciting electrode 2 is provided almost in the middle of a piezoelectric substrate 1, only the vicinity of the exciting electrode 2 of the piezoelectric substrate 1 is polarized in the broadwise direction, then part of a lateral wave component of the thickness longitudinal vibration is reflected at a border between a polarized region 5 and a non-polarized region in the piezoelectric substrate 1 toward the polarized region 5.
