An electrostatic recorder includes first drive pulse generators each for generating high voltage pulses in response to recording signals and second drive pulse generators so driven in turn as to generate high voltage pulses in response to outputs from a ring counter. Outputs from said first drive pulse generators are respectively supplied to recording electrodes via diodes, and outputs from said second drive pulse generators are respectively supplied to the corresponding electrode groups of said recording electrodes via respective resistors connected to the recording electrodes of the electrode groups in a manner corresponding thereto.

In order to divide the inside space of the cabinet into at least two with a speaker being the center, obtain a plurality of emitted sound energies through openings constructed in each divided sphere, and utilize a cabinet of a loudspeaker apparatus as a sound echo box, a partition wall 4 is disposed at a right angle to a baffle board 2 or a front board 7, passing through the center O of a speaker 3 disposed on the baffle board 2 or the front board 7 of the cabinet 6, and divides the inside space of the cabinet 6 into at least two of an upper chamber 11U and a lower chamber 11D, so that sound energies are emitted from openings 8 and 9 which are provided in each chamber of 11D and 11U, respectively.

In a thermal transfer recording method for use in a recording apparatus using a roll of recording paper of an ordinary paper material wound about a core and a strip of ink ribbon would about an ink ribbon feeding roll, recording is effected by means of a thermal head while both the recording paper and the ink ribbon are transported forwardly in the superimposed state. During transportation of the recording paper and the ink ribbon after the recording, they are parted away one from the other and only the recording paper is transported to an automatic cutter by means of which a part of the recording paper on which recording has been effected is cut off. After completion of cutting operation an unused parts of the recording paper and the ink ribbon are transported backwardly to the position where the leading end of the thus returned recording paper is located in the proximity of the thermal head.

A paper circulating assembly is provided for use in a field sequential printing apparatus such as a facsimile. The facsimile includes an ink ribbon having multiple color ink segments. A piece of paper is conveyed ultimately into a printing paper path and to the ribbon and printing platen for printing. The printing platen conveys the leading edge of the printed paper to a gripping arm of the paper circulating assembly. After a predetermined time period, the leading edge of the paper rests in the gap created between the gripping arm and the gripping platen, and the gripping arm closes against the gripping platen. Thereafter, the secured leading edge is conveyed to a recirculating paper path which flows into the printing paper path, and stays in this position until the trailing edge of the printing paper is just about to enter the printing paper path. During this time, the portion of the paper which lies between the gripping arm and the printing platen gathers in a loop in a paper loop area. Afterwards, the gripping platen is rotated and the gripping arm moves away from the surface of the gripping platen, thereby releasing the leading edge of the printing paper. Further rotation conveys the leading edge of the paper into the printing paper path, just behind the trailing edge of the printing paper for printing the subsequent color of ink. This process continues until all ink colors have been printed onto the paper.

To read a document accurately and produce an image signal faithfully representing the document, an image reading method and apparatus adopts various means, of "latching an average light-shielded signal in a digital form", "using an average light-shielded signal resulting from averaging output signals of a plurality of light-shielded pixels as a black reference signal", "replacing that part of an image signal in which an average light-shielded signal is larger than an effective pixel signal in level with a signal of a zero level", "driving CCD sensors at such timing as to allow effective pixel signals output from the CCD sensors to be continuous in time" and "setting DC offset voltages of signals output from CCD sensors to a predetermined clamp potential."

A pressure fixing device for a recording medium comprises a pair of frames, a first roll rotatably supported by the frames, two pair of guide members attached individually to the frames to be movable at right angles to the axis of the first roll, second and third rolls disposed along the first roll so that both ends of the rolls are supported individually by the guide members for rotation, the recording medium being passed between the first and second rolls, and a mechanism for urging the second roll toward the first roll. The mechanism including a pair of compression coil springs extending along the axes of the rolls to apply an urging force in its extending direction, a pair of pressure levers rockable around an axis normal to the axes of the rolls and the moving direction of the guide members, the pressure levers receiving the urging force of the coil springs to urge the second roll toward the first roll. The urging force of the compression coil springs is controlled to adjust the pressure between the first and second rolls through the pressure lever and third roll.

A light emission element array comprises a substrate, a plurality of light emission elements such as light emitting diodes aranged linearly in a row on the substrate and a rod like, i.e., columnar, light converging lens unit arranged above the light emission element row in parallel thereto and adapted to diffuse and simultaneously converge the transmitted light. The light emitting surface of the light converging lens unit is made rough by a chemical treatment, blast treatment or other means.

In a thermal transfer recording method of the type using a strip of repeatedly usable ink ribbon wound about an ink ribbon feeding roll, recording is effected by means of a line scanning type thermal head while recording paper and ink ribbon are transported forwardly in the superimposed state. At every time when recording has been achieved both the recording paper and the ink ribbon are released from the clamped state which is caused by means of a combination of platen roller and thermal head and thereafter the ink ribbon is transported backwardly by a distance shorter than the length of a single page. A short part of the ink ribbon transported backwardly on which recording has been effected is put in use again for next recording operation.

An apparatus for distributing materials into a blast furnace using no bell. The apparatus has a material distributing hopper disposed for a rocking motion around the central axis of said furnace. The rocking motion of the material distributing hopper is caused by an axial movement and rotation of a single drive shaft disposed outside the furnace.
