In a data transfer apparatus, as one substation in a loop type signal transfer system, e.g. for use in an automatic machine, synchronization information and address information are received and the address is checked by an address coincidence circuit; when address coincidence is detected the data information in the received signal is replaced by serialized data which is contrived by parallel-serial conversion of the parallel input data at the substation; therefore there is no need of once storing the entire received signal transferred, and therefore, high speed data transfer results.
摘要:
A method for the production of reformed p-vinylphenol polymers which are lightened in color comprising treating a p-vinylphenol polymer under heating at about 150.degree. C. to about 350.degree. C. in the presence of an amine, and if optionally, in the additional presence of an acid compound and/or a reducing agent, and if necessary, in the additional presence of an inert solvent.
摘要:
A knock control system which includes a knock control unit constructed of a transducer portion for detecting vibrations of an engine and converting the detected vibrations into an electric signal, and a knock signal processing unit for delivering a signal indicative of the occurrence of a knock in dependence upon a receipt of the knock signal from the transducer portion. The knock signal processing circuit controls the ignition timing of the internal combustion engine on the basis of the knock signal from the knock control unit. At least one of the transducer portion and the knock signal processing circuit unit of the knock control system is mounted on a portion of a distributor which has a fixing base portion at a part of the housing thereof.
摘要:
A process for the production of p-vinyl phenol by the dehydrogenation of p-ethyl phenol in a gaseous phase in the presence of a catalyst and a diluent wherein the dehydrogenation of p-ethyl phenol is effected with phenol and/or p-cresol being present in the reaction system in an amount of 5 to 50 wt % of the amount of p-ethyl phenol.
摘要:
A graft copolymer comprising a hydrocarbon polymer main chain and a side chain composed mainly of a styrene compound of the following formula (I) ##SPC1##wherein R is a hydrogen atom or an R'CO group, in which R' is a hydrocarbon group having 1 to 20 carbon atoms, and a polyene compound grafted to the hydrocarbon polymer main chain and a process for preparing the graft copolymer comprising graft-copolymerizing the above copolymer components with the hydrocarbon polymer by ionizing radiation. The graft copolymer is especially suitable as an ion-exchange membrane or a basic polymer matrix for an ion-exchange membrane.

摘要:
An image forming device is disclosed. The device includes a toner-image forming unit which forms a toner image; a transfer unit; a fixing unit; a paper-output unit; a drive unit; a first drive-power transmission gear; a second drive-power transmission gear; a gear housing; a first positioning unit which positions the fixing unit relative to a device body; and a second positioning unit. The second positioning unit positions the paper-output unit relative to the device body in the direction of a gap between the first drive-power transmission gear and the second drive-power transmission gear by engaging the gear housing with the device body.
