Title: Semiconductor storage element
Inventor: SON JEONG-HWAN
IPC: H01L27/12
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To raise the integrated degree of a semiconductor storage element and to facilitate formation of a gate electrode by a method wherein a switching element is formed of a gated diode of a constitution wherein a node joint is formed under the side on one side of the sides of the lower part of the gate electrode and the gate electrode is superposed on a field oxide film on the other side of the lower part. SOLUTION: First and second field oxide films 33a and 33b are formed in a well 32 and an active region of a gated diode is limited. Moreover, heavinly doped P-type impurities are doped to the well 32 to form a node joint 39 in such a way as to come into contact with the first field oxide film 33a formed on the side on one side of the sides in the interior of the well 32 and a gate electrode 37 formed on the upper part, which is located between the second field oxide film 33b and the joint 39, of the well 32 is superposed on the film 33b and the joint 39. That is, in the gated diode which is used for a switching element, the joint 39 is formed under the side on one side of the sides of the lower part of the electrode 37 and the electrode 37 is superposed on the oxide film 33b on the other side of the lower part of the electrode 37.
Patent JP-H0244782-A (JP)
Title: Superconductive element and manufacture thereof
Inventor: YAMAMOTO KEISUKE
IPC: H01L39/24
Filed: 1988-08-05
Abstract: PURPOSE:To make it possible to form a desired or excellent superconductive film even if various kinds of substrates are used by providing an intermediate layer on the substrate before a superconductive film is formed on the desired substrate, and then providing a transition layer. CONSTITUTION:In this structure, a transition layer 3 is laminated on a substrate 1 through an intermediate Iayer 2, then a superconductive film 4 is laminated. The thermal expansion coefficient of the intermediate Iayer 2 is made similar or equal to the thermal expansion coefficient of the substrate 1. The composition of the transition layer 3 in the laminating direction is changed from the composition of the intermediate layer 2 into the composition of the superconductive film. Therefore, stress strain becomes hard to occur at the interface between the substrate 11 and the intermediate layer 2. The stress strain at the interface due to the disagreement in thermal expansion coefficients of the intermediate layer 2 and the superconductive film 4 is alleviated with the transition layer 3. As a result, durability and heat resistance as the element as a whole are improved.

Title: Fiber-thread-speed measuring device of winding apparatus
Inventor: FUERUDEINANTOOYOOZEFU HERUMANS
IPC: G01P3/80
Filed: 1993-08-05
Abstract: PURPOSE: To perform precise measurement by setting area for a model traveling time by using a signal proportional to a yarn speed and locking in a closed control circuit at a correct dead time maximum value. CONSTITUTION: Detection signals from sensors 6, 6' are fed to a delay element 12 and a balance regulation point 12' individually, and by means of the element 12, a signal sequence YM(T) obtained by shifting a signal sequence x(t) by a model dead time τ is differentiated (13) so as to be inputted to a multiplier 14. A deviation between the signal sequence YM(t) and a signal sequence y(t) for a regulation point 12' is inputted (14), and its product is fed to a feedback coupled integrator 11. If the deviation e(t) is zero, the integrator 11 does not send a pulse to the element 12, and the maximum correlation is attained at the time τ similar to a yarn traveling time T. If the deviation e(t) is not zero, follow-up regulation of the time τ is carried out according to the deviation e(t).  In this process, a pulse generator 8 detects a peripheral velocity of a driving drum 4 and sets a proper maximum value area for the time τin the integrator 11 on the basis of a voltage signal proportional to the converted (10) yarn speed. In this way, lock-in at an erroneous balance point τ in the closed loop control circuit can be prevented.

Title: Switched capacitor circuit
Inventor: ARAI TOSHIO
IPC: H03H19/00
Filed: 1984-09-19
Abstract: PURPOSE:To improve the amplitude distortion and phase distortion by increasing the ratio of an input sampling time out of the input sampling time and a holding time in one period of a capacitor circuit using a factor multiplying circuit. CONSTITUTION:In this invention, the ratio of the input sampling time TS to the holding time TH is changed, i.e. the input sampling time TS is increased as large as possible as compared with the holding time TH. If the input sampling time TS is set up to a long period within the range that the movement of the charge of capacitors C1, C2 and the setting of an operational amplifier OA will have been completed, the following time of the output to -C1/C2 times the input is expanded, so that the distortion can be improved. Thus, the amplitude distortion and phase distortion can be improved only by changing the driving timing of the switch in the switched capacitor circuit and the circuit can be widely applied to a factor multiplying circuit requiring high accuracy since said improvement can be attained easily by a general logical circuit.

Title: Preparation of phosphor
Inventor: NAN TORI TORAN
IPC: H01L31/09
Filed: 1994-08-19
Abstract: PURPOSE: To provide a sheet element for effectively transferring a X-ray pattern into a pattern of the visible light or the light of a wavelength to which a photoelectric transfer element has the sensitivity, with high resolution. CONSTITUTION: The fine mesa arrays having the side faces 25 inclined by about 20-45deg. to the base surface, and a top face 30 in parallel with the base, are formed on a translucent base sheet 10 at an interval smaller than the desired resolution. The alkali-halogenated phosphor such as CsI is accumulated on the base by a means such as vacuum evaporation, by the thickness of 30-1000μm, and annealed at about 150-300deg.C. The phosphor is hardly accumulated on the mesa inclined face, and is accumulated on the base surface in the shape of column in the vertical direction. The base surface is cracked much in the vertical direction, when the annealing is performed. Then a light reflective substance such as Al, is accumulated on the same, or a protective film is formed.  Accordingly, the light transferred from the X-ray is not diffused in the transverse direction in the phosphor film because of the cracking and the column structure, thereby the high resolution can be obtained.

Title: Method and device for optical signal amplification
Inventor: AOKI YASUHIRO
IPC: G02F1/35
Filed: 1987-08-06
Abstract: PURPOSE:To widen effective gain band width and to amplifier signal light excellently by using light which contains plural frequency components with narrower frequency intervals of the Brillouin gain band width of an optical fiber as exciting light. CONSTITUTION:The exciting light of this method has frequency components shown in a figure and their frequency intervals are about 70MHz and narrower than 100MHz as the Brillouin gain band width. Consequently, signal light of 100Mb/s can be amplified in this case almost without any waveform distortion. When a semiconductor laser which oscillates in single longitudinal mode like before is used as an exciting light source and the signal light of 100Mb/s is amplified for comparison with this method, large waveform distortion which can be allowed in optical communication application is observed, but no waveform distortion is generated by this method and the signal light is amplified excellently.
