Title: Production of magnetic head
Inventor: SATO MASAJI
IPC: G11B5/23
Filed: 1989-07-29
Abstract: PURPOSE:To prevent the generation of a pseudo gap due to an oxide protective film and to improve the magnetic characteristic by providing an oxide protective film on the gap forming surface side of a ferrite core forming a magnetic head core, removing the protective film on the gap forming surface by polishing and forming the film of a ferromagnetic metal thereon. CONSTITUTION:The oxide protective film 12 is formed on the gap forming surface 15 of a ferrite core 11 and its surrounding groove, and only the protective film 12 formed on the surface 15 is removed by polishing. A magnetic metallic film 13 is formed on the gap forming surface 15 of the core 11 freed of the film 12 and on the film 12 remaining on the track groove forming surface to complete a magnetic head 10. Consequently, the oxide protective film is not formed on the gap forming surface, only the ferromagnetic metal film is formed thereon, and a pseudo gap due to the oxide protective film is not generated. Furthermore, since the track groove part is covered with the oxide protective film, the deterioration of ferrite is reduced.

Filed: 1983-10-25
Abstract: PURPOSE:To obtain white balance by gating only the center part out of modulation output of an image signal, operating an alarm circuit by the output and copying a white object without using a diffusion plate. CONSTITUTION:Outputs of color difference signals from color difference circuits 4 and 5 are added to a modulation circuit 9, thereby obtaining modulation outputs. Only the center part out of the modulation output is taken out by a gate circuit 10. After the center part is wave-shaped by a shaping circuit 11, the result is supplied to a level detector 12. If a redish object image is picked up, the level detector 12 outputs a detected signal, which is added to an alarm circuit 13 because the redish object image exceeds the reference of a white level at the level detector 12. At this time, the alarm that the detection signal is unsuitable for the reference data of white balance adjustment is given. In such a manner, white balance is obtained by using the white object as reference data without using the diffusion plate.

Abstract: PURPOSE:To prevent the occurrence of a silent period and the omission of screens by revolving a disk at a higher speed by a prescribed multiple at fast reproduction, separating the voice data out of the read-out data to sequentially read out the stored data, and reproducing these data with a series of processing operations including the extension of a prescribed time base, etc.. CONSTITUTION:At fast reproduction, the data are read out of a disk 60 by a read means 67 at a revolving speed higher than a prescribed level by 5/3 times set by a drive means 91. Then the data corresponding to each block are outputted. A separation means 7 inputs these data and separates the voice data out of others to output the voice data. The voice data are stored in a memory circuit 78. A voice processing output means 82 reads successively the voice data out of the circuit 78 and applies the prescribed time base extension processing to the voice data for reproduction of the voice signals. A detection means 71 outputs a control signal to a selection means 94 while the number of blocks is reduced down to a lower limit level from an upper limit level for those data unprocessed by the means 82 out of the voice data stored in the circuit 78. Then the means 71 stops the input of voice data to the circuit 78. thus no track jump occurs so as to prevent the occurrence of a silent period and the omission of screens.

Abstract: PURPOSE:To improve the transmission efficiency in an ATM transmission network by allowing a terminal interface section at a receiver side to control the permission of data transmission from an asynchronous transmission network to a terminal equipment at a point of time when a cell is received and the inhibit of data transmission to the terminal equipment after lapse of a prescribed time. CONSTITUTION:A sender side terminal interface section 20A detects a MODEM control signal (CD signal) S6 to identify whether a transmission data from a terminal equipment 1A is valid information or invalid information, processes only the valid information into a cell and sends it to an asynchronous transfer mode (ATM) transmission network 3. On the other hand, a receiver side terminal interface section 20B monitors the reception state of a cell S4 sent from the transmission network 3, permits the data transmission to a terminal equipment 1B and the data transmission is controlled to be inhibited to the terminal equipment 1B at a point of time after a prescribed time elapses after the cell S4 is not received. Thus, since the transmission of an invalid information cell on the transmission network 3 and reproduction output processing of the invalid information cell at the receiver side are eliminated the transmission efficiency by the excluded processing is improved.

Abstract: PROBLEM TO BE SOLVED: To make steel ball evenly machined without causing differences in diameter by making the streams of steel balls in the guide path of rotating conveyer flow even and numbers of passing through the polishing circuit equal. SOLUTION: Inner circumferential surface of an outer casing 27 of a rotating conveyer 30 is bonded with a material having low friction coefficient 31, e.g. fluororesin as a sliding surface, thereby, steel balls conveyed therethrogh are free from frictional resistance. The frictional resistance is small compared with the sliding friction between the steel balls, so the steel balls in contact with the bonded low friction coefficient material 31 do not rotate by themselves, and their advancing speed is almost the same as the speed of steel balls advancing without contact with the material having low friction coefficient 31, and its speed is almost the same as the speed of a bottom surface 26a, thereby, advancing streams of steel balls in the guide path of conveyer 30 are evenly moved. Consequently, numbers of passing through polishing process of the steel balls are equalized, and scratches on the surface of the steel balls are prevented and the finished surface condition of the steel balls are not affected.
