摘要： In a recording/reproduction apparatus, when a rotational-speed-mode setting instruction is received from an I/F unit, a CPU reads out a control procedure from a storage device, controlling other components in accordance with the procedure. As a result, a node switch driving circuit controls field windings of a pulse motor to a switching sequence, driving the pulse motor to rotation at a predetermined rotational speed. Since the control is feedback control, the pulse motor rotates at the predetermined rotational speed specified by an instruction setting a rotational-speed mode with a high degree of reliability. Data can thus be recorded into and reproduced from a magnetic disk at a variable speed.

摘要： A method for developing electrostatic latent image on a rotating photoconductive drum by a magnetic developer transported by a rotating developing roll disposed opposite to the photoconductive drum, the developing roll being made of a cylindrical permanent magnet having on circumferential surface thereof equispaced magnetic poles extending along the axial direction. In the method the magnetic poles are equispaced by an inter-pole pitch of 0.5-10 mm, the photoconductive drum and the developing roll are rotated so as to move in opposite directions in an developing zone, and the ratio of peripheral speeds of the developing roll and photoconductive drum are regulated within 1 to 5. By the above method, an electrophotographic imaging apparatus can be reduced in the size thereof while reproducing high-quality images.

摘要： A spurious signal SSP whose frequency spectrum is located at frequencies [(N + (1/2)).fh] is multiplexed with a luminance signal Y so as to keep an interleaved relation between the spurious signal SSP and the luminance signal Y and the resultant signal is transmitted. When the spurious signal SSP is detected, the recording operation is inhibited. The spurious signal SSP is multiplexed with the luminance signal Y at a level such as not to exert an influence on the picture quality when the video signal is reproduced and seen by a monitor screen.

摘要： A picture signal recording system comprises a high-definition broadcasting station 1, an artificial satellite 2, a television receiver 3 and a video signal recording apparatus 5. A pilot signal P is superimposed on a luminance signal Y at the broadcasting station 1. This pilot signal P does not give any adverse influence to an image reproduced on a TV monitor and is detectable from the luminance signal Y. A frequency of this pilot signal is selected to be smaller than the frequency of the luminance signal Y, a superimposing timing thereof is set to a head position of the luminance signal Y, and an amplitude thereof is varied with respect to a grey level as a variation center. The pilot signal P superimposed on the luminance signal Y is detected by a pilot signal detecting circuit 53 within a video signal recording apparatus 5. The picture signal is recorded on a video tape 11 and rerecording prohibit information is recorded in a reserved area by a picture signal recording process circuit 51. When the video tape 11 on which this rerecording prohibit information has been recorded is reproduced, the reproduced picture signal is prohibited to be rerecorded.

摘要： An audio signal recording apparatus and method for recording an video signal (e.g., a half field) and at least four channels of audio signals corresponding to the video signal to a plurality of tracks on a tape. The audio signals are recorded to recording blocks in an audio recording area which are separated from a recording area for the corresponding video signal in accordance with a priority rating. More specifically, the at least four channels of audio signals are divided into groups each having a plurality of channels. The audio signal recording area is divided into a plurality of recording blocks in the longitudinal direction of the tracks and each group of audio data is recorded to one of the audio signal recording blocks. Each group of audio data is assigned a priority rating depending on the importance of the data contained therein. Audio data having a high priority are recorded to blocks that are located further away from the track ends than those for audio data having a low priority. Since the contact fit between the tape and a recording head at the track ends is unstable, by recording the audio data of high priorities in blocks located relatively for away from the track ends where the tape-to-head contact fit is more stable, deterioration in sound quality is minimized for the important data upon reproduction.
摘要翻译：一种音频信号记录装置和方法，用于将对应于视频信号的视频信号（例如，半场）和至少四个音频信号的信道记录到磁带上的多个磁道。音频信号被记录在音频记录区中，根据优先等级与对应的视频信号的记录区分开。更具体地，至少四个声道的音频信号被分成具有多个声道的组。音频信号记录区域在轨道的纵向被分成多个记录块，并且每组音频数据被记录到音频信号记录块之一。根据其中包含的数据的重要性，为每组音频数据分配优先级。具有高优先级的音频数据被记录到比轨道端更远的块比具有低优先级的音频数据的块。由于磁带和轨道端之间的记录头之间的接触配合是不稳定的，所以通过将高优先级的音频数据记录在相对较远的位置，以便远离磁带头接触配合的轨道端更稳定，劣化对于重放时的重要数据，音质被最小化。

摘要： A device for recycling residual developer particles which are removed from a photoconductive element by a cleaning unit in an electrographic copier or printer is disclosed. The device comprises a first tube connected to the cleaning unit and a second tube which is connected to the first tube and leads to the developer unit. The second tube is disposed along the developer unit. The residual particles are transferred from the cleaning device through the first tube and into the second tube. The second tube is provided with holes spaced at predetermined distances from each other. The residual particles fall through these holes and co-mingle with developer material stored in the developer unit. In a preferred embodiment, the holes increase in size as one goes along the second tube. In another preferred embodiment, an auger is used to deliver the residual particles to the first tube. A second auger is disposed within the second tube to move the residual particles over the holes. An even distribution of residual particles within the developer unit is thereby attained.
