Abstract: In a polyphase electric motor, a voltage is sequentially applied to a plurality of windings on a phase-by-phase basis. Then, there is sensed a rotational speed of a rotor, which is rotated by a rotating magnetic field that is generated by sequentially flowing an electric current in the windings on the phase-by-phase basis upon the sequential application of the voltage to the windings. Then, an oscillation frequency of a periodic oscillation, which is generated in the motor at the sensed rotational speed of the rotor, is obtained. Thereafter, it is determined whether the obtained oscillation frequency is a predetermined resonance frequency. Next, the voltage to be applied to the windings is corrected in a manner that reduces a resonance generated in the motor when a result of the determination indicates that the obtained oscillation frequency is the predetermined resonance frequency.

Abstract: A dissolution testing apparatus comprises a vessel plate on which a plurality of test vessels are mounted. Each test vessel has a heat generation portion, which includes a transparent ring-shaped heat generating sheet member wrapped around the cylindrical portion of the vessel so that the heat generation portion is held thereon in a freely detachable manner. Additionally, the heat generating portion includes a transparent pressing sheet member. The dissolution testing apparatus has a heat control block, which includes a system control unit, a dc power supply and displays. The heat generation portion, if defective, can be easily replaced without the need to replace the main body of the vessel, thereby providing cost savings. Further, by providing an unobstructed observation window between an upper side region and a lower side region of the heat generating sheet member, progress of the dissolution of a pharmaceutical preparation inside the container main body can be observed easily from the outside.

Abstract: A sign language telephone device is offered which enables an aurally handicapped person who uses the sign language to converse with a normal person at a distant place who does not know the sign language. The sign language telephone device is placed on the side of the aurally handicapped person, and hand gestures of the sign language inputted from a sign language input means are recognized as the sign language, and the recognized sign language is translated to Japanese. The translated Japanese word train is converted to synthesized voices and it is transmitted to a videophone on the side of a normal person. The voices from the videophone are recognized, and the recognized Japanese is translated to the sign language to generate sign language animations and they are displayed on the screen of a TV set on the side of the aurally handicapped person.

Abstract: A sign language editing apparatus includes a glove-type sensor for converting movement of fingers in the sign language into an electrical signal to produce time series data of sign language words, a sign language word data editing device for adding predetermined additional data to the time series data inputted from the glove-type sensor to process the time series data, a sign language word dictionary for storing the time series data of sign language words processed by the sign language word data editing device, a sign language sentence data editing device for reading out the time series data of sign language words stored in the sign language word dictionary in accordance with the predetermined characters inputted from the input unit and adding predetermined additional information to the time series data of sign language words to produce time series data of sign language sentence, a sign language animation synthesizing device inputted with the time series data of sign language sentence produced by the sign lan

Abstract: A chemical reducing solution obtained by using an alkali boron hydride as a reductant and adding thereto a water-soluble, polyoxyethylene chain-containing organic compound having a molecular weight of 200 or above molecule as an additive has merits in that it can reduce copper oxide to metallic copper while maintaining the needle-like form of copper oxide as completely as possible and the reduction can be completed in a short period of time by a simple procedure, so that the chemical reducing solution is successfully usable in a process for producing a multi-layer printed circuit board.

Abstract: An information output apparatus which outputs guide information in combination with image, text, voice and sign-language so that hearing impaired, handicapped people can easily recognize the guide information. The sign-language is automatically generated by computer graphics on the basis of text information inputted to the apparatus. A user can edit the generated sign-language. When it is desired to perform a generating operation over additional sign-language information, a transitional picture is automatically inserted between the sign-language words to provide clear discrimination between the words. The inserting manner can be specified by the user.

Abstract: An electrically conductive powder having good stability against oxidation, good storage stability, good in anti-migratory action and capable of constituting electrically conductive composition having high electrical conductivity and good resistance to heat and the wet, may be constituted by copper particles, a silver coating material coating a part or the total of the copper particles and a titanate coupling agent combined to the copper particles and/or the silver coating material.

Abstract: A process for treating a surface of a metal such as copper with a liquid composition comprising (I) copper ions, a complexing agent, a reducing agent, a pH adjusting agent, water, and (II) a nitrogen-containing organic compound such as heterocyclic compound or containing --N.dbd. and --NH.sub.2 and/or --OH groups in its molecule can give multilayer printed wiring boards having excellent adhesive strength and line definition of inner layer copper conductors with long shelf life.
