Abstract: A stator of a dynamo-electric machine which is capable of raising the space factor in each slot and which can easily be assembled incorporates first coil pieces, each of which has a width at the lower portion of the slot being smaller than the width at the upper portion of two slots; and second coil pieces arranged to be fitted to teeth adjacent to the tooth to which the first coil piece is fitted so as to be inserted into the empty space for filling the space. The first and second coil pieces are alternately inserted into the slots of the stator core. The empty space in the slot formed after the first coil piece has been inserted has sides extending parallel with the adjacent tooth or is gradually widened toward the upper portion of the slot. Therefore, the second coil piece can easily be inserted into the slot without interference with another member. Thus, the slots can be filled with the second coil pieces so that the space factor can be raised.

Abstract: This invention is directed to a facsimile machine adapted for being connectable with an external computer and being capable of conducting a certain communication operation upon receiving a command data in a certain command type from the externally connected computer in handshaking manner. The facsimile machine includes a communication interval extension means for extending a data communication time interval with the externally connected computer by a predetermined time duration; and operation control means for carrying out the communication operation in the extended communication time interval and a facsimile machine oriented operation in a vacant time residing in the data communication time interval when the facsimile machine oriented operation and the communication operation are commanded at the same time to perform a parallel processing of the communication operation and the facsimile machine oriented operation.

Abstract: A communication device includes: T/D data generating means for generating T/D data according to a calendar; storage means for edittably storing T/D data regarding a beginning and an end of a specified time period; judgement means for judging whether the T/D data generated by the T/D date generating means is in the specified time period; T/D data changing means for changing the T/D data of the T/D generating means to T/D data according to the preset T/D data; wherein the T/D data regarding the beginning and the end of the specified time period is set or replaced with a data supplied via communication line from a certain communication center.

Abstract: A drive assembly including an electric motor, and a differential gear device which is integrally incorporated within a rotor of the electric motor and which has a gear case rotated with the rotor and a pair of output shafts that are disposed coaxially with the rotor and rotated by rotation of the gear case with the rotor, wherein the gear case of the differential gear device is supported by a housing of the electric motor through bearings interposed therebetween.

Abstract: In a facsimile remote diagnostic system according to the present invention, when a remote diagnosis rejection mode is selected, data having no remote diagnostic function is set as data relating to a remote diagnostic function in a pre-procedure signal sent out from the facsimile, whereby remote diagnosis is stopped in the pre-procedure stage. Consequently, a user of the facsimile can reject the remote diagnosis with his or her intention.

Abstract: A lead frame material comprises a base plate consisting of copper or copper alloys, and a protective coating formed on the upper or the both surface of the base plate. The protective coating is composed of at least one metal selected from the group consisting of gold, gold alloy, silver, silver alloy, palladium and palladium alloy, and has a thickness of 10-500 angstrom. The protective coating is formed by means of vapor deposition. It is possible to form an intermediate coating of nickel or nickel alloys between the surface of the base plate and the protective coating, by means of vapor deposition or wet plating. The suitable thickness of the intermediate coating is within the range of 50-20000 angstrom.

Abstract: The invention relates to carbonaceous bricks having resistance to fire and corrosion, capable of withstanding mechanical impact to which the conventional carbonaceous bricks were vulnerable, and usable in an oxidizing atmosphere, and the method as producing the same. The invention has for an object to obtain carbonaceous bricks having said high properties by mixing less than 60 weight % of inorganic material with 40.about.100 weight % of pellets consisting of carbonaceous material containing substantially more than 70 weight % of carbon and a bonding agent comprising pulverized phenol resin, liquid thermosetting resin and/or setting accelerator, bricks formed therefrom containing more than 40 weight % of carbon.

Abstract: Disclosed is a substance which is obtained by coating the surface of a specific iron-containing substance, through a specific procedure, with a material composed mainly of aluminum sulfate. The substance thus produced is useful as a catalyst for the removal of nitrogen oxides from an exhaust gas.

Abstract: An excellent catalyst for the reduction of nitrogen oxides is obtained by mixing a specific aluminum-containing substance with a specific iron-containing substance in water and baking the resultant precipitate.

Abstract: Disclosed is a substance which is obtained by calcining an iron hydroxide or a water-containing iron oxide and coating the surface of the resultant calcined product with alumina. This substance is useful as a catalyst in the removal of nitrogen oxides from an exhaust gas containing the nitrogen oxides.
