To provide a negative photosensitive resin composition which is capable of imparting good ink repellency to a cured film, particularly to the upper surface of partition walls, and which has characteristics such that an ink repellent agent is less likely to remain in opening sections defined by the partition walls even without UV/Oirradiation treatment, and the ink is permitted to uniformly wet-spread without unevenness. A negative photosensitive resin composition characterized by comprising (A) an alkali-soluble resin or alkali-soluble monomer, which has a photo-curability, (B) a photopolymerization initiator, (C) an ink repellent agent having fluorine atoms, and (D) a compound which is a partially hydrolyzed condensate of a hydrolysable silane compound mixture containing a hydrolysable silane compound having a mercapto group and a hydrolysable group and/or a hydrolysable silane compound having a group with an ethylenic double bond and a hydrolysable group, and which has no fluorine atom.

A composition for a light-scattering film contains fluorine-containing resin fine particles each including a copolymer of a first ethylenically unsaturated monomer containing fluorine with other ethylenically unsaturated monomer component, and having an average particle diameter of 0.8 to 5.0 &#x3bc;m; and a transparent resin having a refractive index of 1.50 to 1.70. Where the other ethylenically unsaturated monomer component is formed of a second ethylenically unsaturated monomer containing no fluorine nor hydrophilic group, the copolymer contains 10 to 60% by weight of the first monomer, and 90 to 40% by weight of the second monomer. Where the other ethylenically unsaturated monomer component is formed of the second monomer and a third ethylenically unsaturated monomer containing a hydrophilic group, the copolymer contains 10 to 90% by weight of the first monomer, 89 to 5% by weight of the second monomer and 1 to 10% by weight of the third monomer.

An organic EL structure is received in a gas-tight casing to construct an organic EL display assembly. The organic EL structure includes a hole injecting electrode, an electron injecting electrode, and at least one organic layer disposed between the electrodes. A desiccant selected from calcium hydride, strontium hydride and a mixture thereof is disposed in the casing out of contact with the organic EL structure. This EL display assembly substantially eliminates the influence of moisture and has a long lifetime.

There is disclosed a data circuit-terminating equipment (DCE) which connects an asynchronous data terminal equipment (DTE) with a PCM trnsmission line having various speeds. Further the DCE can satisfy recomendations of the V25 bis of CCITT. The DCE includes a PLL obtaining a clock from the line, a timing generator generating timings for circuits, a mapping circuit mapping to make data from the DTE match into the line speed, a sending register converting transmission speed of the mapping circuit output to send to the line at the instructed period, a receiving register receiving data from the line to deliver data with the required speed during the required period for the DTE, and a demapping circuit receiving the receiving register output to demap and send to the DTE. In the DCE satisfying the recommendations, the demapping circuit ANDs a clear-to-send signal and bits indicating the synchronized state to send the clear-to-send signal, and a short line shorting the clear-to-send signal and a carrier detect signal is employed.

CMI code has many features, but the interference on a transmission line resulted from radiant noise is an unavoidable problem. In the invention, WALSH 1 code is employed to solve the problem. Clock pulses having a frequency twice that of code on a transmission line in the WALSH 1 code are extracted. The extracted clock pulses consists of zero phase clock pulses and pi phase clock pulses, wherein the zero phase clock pulses are accurately extracted. An embodiment comprises an clock extraction circuit for extracting extracted clock pulses of 2f.sub.0 from a receive pulse train of frequency f.sub.0, a latch circuit for latching the receive pulse train with the extracted clock pulses, a frame synchronizing circuit for obtaining frame pulses synchronized with the extracted clock pulses from the latched output pulses, a zero phase separation circuit for obtaining zero phase clock pulses from the extracted clock pulses and the frame pulses, and a regenerative discrimination circuit for obtaining a regenerated pulse train from the zero phase clock pulses and the latched output pulses. The regenerated pulse train has the same pattern as that of the original code from which the receive pulse train is converted by the WALSH 1 code.

A time division multiplex telecommunications system is disclosed as adapted for a key telephone system providing for intercommunication between any two of a series of key telephone sets in cascade connection to a switching control circuit, possibly with facilities for association with the nationwide telephone network. The control circuit receives from the tandem connection of telephones an outgoing data signal of time division multiplex frame format having a succession of frames each comprising a frame sync signal and channels of outgoing data from the respective telephones. Rearranging the channels of data in the received outgoing data signal, the control circuits delivers back to the successive telephones an incoming data signal of similar frame format. Each telephone is equipped for rearrangement of the frame sync signal and data channels of the incoming and outgoing data signals, with the result that all the telephones can be of the same circuit configuration.
