    Abstract: It is an object of the present invention to provide a cathode catalyst for fuel cells containing platinum and iron which can maintain the durability of a battery and can make a battery high output. The cathode catalyst for fuel cells comprises a supporting layer which consists of an alloy containing platinum and iron and further containing the third component which has an affinity for iron including one or more sorts of elements selected from the group consisting of tungsten, titanium, molybdenum, rhenium, zinc, manganese, tin, tantalum and rhodium, and a support on which the supporting layer is loaded. A catalyst using an alloy containing platinum and iron enables the batteries to become high output. By alloying one or more sorts of elements of the third component which has an affinity for iron with an alloy containing platinum and iron, it is possible to prevent eluting of the iron into the electrolyte.

    Abstract: A laser light flux is divided and synthesized so that its light intensity distribution is changed from a Gaussian distribution to a non-Gaussian distribution. When a laser light flux having a Gaussian distribution is irradiated onto a dividing prism, it is divided into a left part and a right part which are refracted right and left inversely from each other. When the right and left parts are incident on a synthesizing prism, they are refracted again and travel to be overlapped with each other on a recording medium. The light intensity distribution on a segment at the apex of the synthesizing prism is weaker at the central part and stronger at the peripheral part. This is because the light fluxes resulting from the division are inverted in their position so that the central part of the Gaussian distribution is separated left and right while the peripheral part with a weaker light intensity is centered.

    Abstract: Plural television cameras situated at monitored sites, each assigned with a particular code, generate image signals of the sites. An image signal transmitting unit receives those signals and transmits an image transmission signal over a transmission a monitoring site. The transmission signal is so formed that one channel of the transmission line which is divided into plural channels is assigned to the transmission of an image signal of high priority sites so as, to reproduce a full motion image of the remote site at the monitoring site and all the signals from the other sites are transmitted on a time-sharing basis through the remaining channels to reproduce frame repetition images. The assignment of the channels is determined by the order (priority) of codes included in an instruction signal from an instruction signal transmitting unit at the monitoring site. An operator can select the order (priority) of the codes.

    Abstract: The present invention relates to a signal diagnostic method for a triple information transmission system. According to this method, using a transmission signal transmitted latest among three transmission signals of three channels, the synchronizing signal parts of the respective transmission signals are synchronized so as to align the heads of information signal parts of the transmission signals, whereupon any error in the information signal parts of the transmission signals is detected. The three transmission signals of the three channels are temporarily stored in three registers. The storage time intervals of the transmission signals in the registers are determined by the transmission time differences between the respective transmission signals and the latest transmission signal. Upon lapse of the predetermined storage time intervals, the transmission signals are fetched from the respective registers.

    Abstract: A data transmission system is disclosed in which the information to be transmitted comprises a plurality of unit information pieces each of which in turn is indicated by a numerical code of a binary number or a binary-coded decimal number having a predetermined number of bits. One of said numerical codes makes up a fundamental matrix of a frequency permutation code comprising a plurality of different frequency signals; the number of times by which the information in the form of numerical codes shifts the elements of the fundamental matrix on the basis of weight constants determined by said number of bits is detected; each numerical code is converted into a permutation code in response to the above-mentioned detection and transmitted at the transmitting end in the form of a plurality of different frequency signals according to the elements of the shifted permutation code; the frequency signals thus transmitted are received and stored in sequence and detection is made as to how many shifts are required in order that the matrix elements of said stored permutation code may be made identical to with the fundamental matrix; and the permutation code is converted into a numerical code by calculation of the detected number of shifts and the weight constants.
