Patent JP-H01251636-A (JP)
Title: Manufacture of dielectric isolation wafer
Inventor: YAMAGUCHI YOSHIHIRO
IPC: H01L21/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a wafer wherein the irregularity of film thickness does not exist, and dielectric strength is large, by forming a film whose etching selection ratio to semiconductor is large, forming an active layer of single crystal on a surface, forming an insulating film on the surface, and directly joining other substrate. CONSTITUTION:By implanting oxygen ion from the surface of a Si wafer, an oxide film is formed in the inside. An active layer 4 of single crystal is formed on the Si layer surface, and an oxide film 5 is formed on the surface. Other substrate 2 is directly joined. A material, whose thermal expansion coefficient is almost equal to the wafer 1, is desirable for the substrate 2, thereby preventing the warp after joining. The Si layer part of the wafer 1 is eliminated by etching. Etchant, whose etching selection ratio of Si and the oxide film is large, is used. As a result, etching halts on the oxide film 1. After a process of element isolation in the wafer, a dielectric isolation wafer is completed. Thus, the dielectric isolation wafer wherein the thickness of the active Iayer is uniform in the wafer, and dielectric strength is large can be manufactured.

Title: 7-ethyltriptophol crystal and its production
Inventor: TAKAYANAGI ZENICHI
IPC: A61K31/40
Filed: 1995-03-31
Abstract: PURPOSE: To produce a new high-purity crystal of 7-ethyltriptophol useful as an intermediate for etodolac as an anti-inflammatory agent by simple operations in high efficiency. CONSTITUTION: A crystal of 7-ethyltriptophol. The crystal preferably has a melting point of 46.5-51 deg.C, powder X-ray diffraction peaks at 12.9 deg., 17.2 deg., 24 deg. and 5.8 deg. (2θ) and/or peaks of an infrared absorption spectrum at wave lines of 1436, 1049 and 748 (cm<-1> ). The crystal is obtained from an oily substance of a crude 7-ethyltriptophol by dissolving it in an aprotic organic solvent such as benzene, treating the solution with an aqueous acidic solution (e.g. an aqueous hydrochloric solution) or a cation exchange resin and subsequently separating crystals from the obtained organic layer. Further, the concentration of the aqueous acidic solution is preferably 1-20%.  Furthermore, the aqueous acidic solution-treatment is preferably carried out at 0-50 deg.C by mixing the aqueous acidic solution into the solution prepared by dissolving the oily substance into an organic solvent.

Title: Static reactive power compensator
Inventor: IROKAWA SHOICHI
IPC: H02J3/18
Filed: 1990-03-26
Abstract: PURPOSE:To ensure the stable operation regardless of the number of driving units by changing the control constant of each unit in response to the total capacity of the drive units. CONSTITUTION:A driver 19 obtains a ratio between the total capacity QT of a static reactive power compensating device SVC set at a substation and the capacity QA of a unit A to be controlled. A divider 20 divides the value obtained by multiplying the current IA of the unit A by a slope reactance XSL by the output of the divider 19. A multiplier 21 multiplies the voltage deviation by the transient gain K and then by the output of the divider 19. Then a control constant is changed so that a substantial constant is fixed when the capacity of the unit to be driven changes and the P.U. value of the impedance of a system is changed to the total capacity of the SVC. Thus the stable operation is always secured irrespective of the number of driving units.

Title: Correcting method for erroneously written character
Inventor: MIYAMOTO HIRONORI
IPC: G06F17/21
Filed: 1993-04-02
Abstract: PURPOSE:To correct an erroneously written character by using a correction pattern prepared by an operator himself and a co-operator by automatically correcting the erroneously written character by using cooccurence relation generated by his own computer and the correction pattern generated by the other computer. CONSTITUTION:Concerning data read from a word lattice file 303, a text correction aid program 301 performs both the automatic correction of the erroneously written character by using the cooccurence relation read from a cooccurence relation file 305 and an intermediate file 309 and the correction of the erroneously written character manually worked by the user and outputs the corrected result to a text file 307. When the user selects the character recognized text to be the object of correction, the erroneously written character in a correcting image is automatically corrected by using the cooccurence relation of the word stored in advance. When any erroneously written character exists in the character recognized text to be the object of correction, the correct character candidates of all the words are displayed, the inputs of both the word including the right character and the cooccurence word are accepted, and the new cooccurence relation is generated and stored from the word including the correct character inputted by the user and the cooccurence word.

Title: Battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M4/50
Filed: 1989-03-28
Abstract: PURPOSE:To improve the discharge voltage of a battery by using as active material for a positive electrode electrolytic manganese dioxide which is obtained by performing electrolysis in an electrolytic bath containing manganese sulfate, sulfuric acid and acid of higher relative viscosity than sulfuric acid or its salt. CONSTITUTION:In case that electrolytic manganese dioxide is prepared for which manganese sulfate and sulfuric acid solution is used as electrolyte, acid of higher relative viscosity than sulfuric acid or its salt is added into the electrolyte to perform electrolysis. When manganese dioxide is electrically broken away, ion or the like resulting from acid of higher relative viscosity than sulfuric acid or its salt is adsorbed to the manganese dioxide to create electrolytic manganese dioxide. Since this manganese dioxide has small grains and a large specific surface, it is fittable for a battery. It is thus possible to improve the discharge voltage of a battery in which the manganese dioxide is used as active material for a positive electrode.

Title: Combustion control circuit
Inventor: INOUE YORIAKI
IPC: F23N5/00
Filed: 1981-05-25
Abstract: PURPOSE:To make control of combustion reliable irrespective of a variation of power source voltage, by constituting that a detecting level is varied according as the power source voltage varies, in a captioned combustion circuit wherein an alternating current is applied to an electrode rod inserted into a flame and a direct current being applied in the flame is detected. CONSTITUTION:A flame electric current reaches to the flame electric current corresponding to a detecting level to a power supply source, and an alarm circuit 7 is actuated when an indoor oxygen density is decreased to a limit density while power supply source voltage 100V is kept unchanged. Then, output voltage of a flame electric current detecting part 5 is increased even if an oxygen density is constant when the power supply source voltage varies to a higher side. But, as one terminal voltage of the second comparator 15 is H level the detecting level varies to a high level. Then, a normal oxygen detecting operation is carried out even if the flame electric current is increased. When the detecting level is varied to a low side the first comparator 14 becomes L level and the one terminal voltage of the comparator 15 is lowered to a fixed value for a normal detecting operation. With this, reliable controll is obtained irrespective of a variation of the power supply source.
