摘要:
A digital transmission network comprises a plurality of transmission terminals and receiving terminals, which are all connected with each other by a transmission line of a metal cable or optical fiber cable in the form of loop. Signals are transmitted by timeshare multiplexing in one direction. An individual time slot which is defined for each transmission terminal by time sharing multiplexing is allocated to each of all transmitted signals. A timing device is inserted into the loop for retransmitting a signal so that the delay time is corrected to the delay time of one frame including the delay time caused by the transmission line, cable and the like so that the consecutive frames are continuous. The transmission line is in single or dual loop. In case of the single loop, the transmission terminal includes a bypass circuit for bypassing a signal input to the transmission line if necessary. In case where the transmission line is in a dual loop comprising optical fiber cables of a working line and backup line, a control signal of loop-back is transmitted to all receiving terminals from a receiving terminal which serves as a central unit to bring all receiving terminals into a state enabling signals to be input from the optical fiber cable of the backup line. A control signal is transmitted which returns the receiving terminals into a state enabling signals to be input from the working line in order of proximity to the central unit for confirming that the receiving terminals are normally operating in order of proximity to the central unit.

Provided is a printer capable of ensuring a large peeling angle at the time of peeling between the transfer film and the ink ribbon by differentiating a conveyance direction of the transfer film at a peeling part on a proceeding passage from the proceeding direction. In the printer which forms an image on a transfer film 46 while feeding an ink ribbon 41 and the transfer film 46 to a print position between a platen roller 45 and a thermal head 40 which are mutually pressure-contacted, the transfer film 46 is wound to form a conveyance passage between a feeding spool 48 and a winding spool 47 in a film cassette 100 which is attached to a device frame in a detachably attachable manner, and a film conveying roller 49 and pinch rollers 32a, 32b are arranged at positions so that the conveyance passage of the transfer film 46 attached to the device frame is displaced to the inside of the cassette by a predetermined amount.

An original plate scanning device for a microfilm copying machine has a guide stand and bearings for supporting a straight shaft member which extends parallel with said guide shaft and is movable linearly relative to the bearing. A semi-solid state lubricant which has an unworked penetration between 200 and 230 is disposed in the bearing for providing a braking force to the moving, straight shaft member.

A registration correction apparatus having interpolation circuits. The interpolation circuits receives digital sampled pixel signals from at least one channel of a plurality of color signal channels. The digital sampled pixel signals have been obtained by sampling consecutive pixel signals. Each of the interpolation circuits generates a digital pixel signal in a desired position between adjacent two of the digital sampled pixel signals by interpolation processing. The desired position between the two adjacent digital sampled pixel signals is set in accordance with a registration discrepancy among the plurality of color signal channels by a control circuit.

A refrigerating machine oil composition for vapor compression type refrigerating machines is disclosed which can be used with either of HCFC refrigerants and HFC refrigerants. The inventive machine oil composition comprises a polyol ester (ester compound) as a base oil. Furthermore, the base oil contains from 1.0 to less than 5.0% by weight of a phosphate, from 0.1 to 2.0% by weight of an alkyl phosphorothionate and/or an aryl phosphorothionate, and from 0.05 to 2.0% by weight of an epoxy compound. The composition is free from sludge formation and insufficient lubricity, which are drawbacks of the polyol ester, due to the synergistic effect of these additives. On the other hand, the inventive composition provides the desirable properties of a polyol ester base oil, namely, good compatibility with refrigerants, high electrical insulating properties, and low hygroscopicity.

A distortion compensating circuit for a power amplifier attains raised compensating accuracy with shorter convergence time by accurately and quickly generating a distortion compensation signal for pre-distortion. An error signal representing the difference between the input and output signals of the power amplifier is generated. From the error signal and the input signal, the coefficients of the third-order intermodulation distortion, fifth-order intermodulation distortion and seventh-order intermodulation distortion are calculated. According to these coefficients, a distortion compensating signal which is characteristically opposite in phase and gain to the intermodulation distortions is generated.

The object of this invention of a float for liquid waste disposal apparatus enables the content inside a container to be easily visually recognizable and allows a faster and steadier solidification of an absorbed liquid waste. The connection plates 5c connects the annular member 5a serving as the guide member to the outer peripheral portion of the cup portion 5b retaining the water-absorptive material 6 wherein the annular member 5a is restrained by the inner wall 26 of the lying member L for preventing the float 5 from revolving in the vertical direction. The liquid waste 21 absorbed from the upper portion and into the lying member L flows downward via the flow path structured with the interstitial portion 27 formed between the annular member 5a and the cup portion 5b and the interstitial portion 28 formed between the inner wall 26 of the lying member L and the annular member 5a.
