A composite video signal is processed for superimposing characters on an image represented by the video signal, where a memory (33) and a character generator (31) used for superimposing the characters at an appropriate position are both controlled by a control unit having an odd-field detector (38), a shift pulse generator (44), a rewrite pulse generator (45) and a window pulse generator (54). The odd-field detector (38) produces an odd-field pulse each time a coming odd field is detected, and the number of the odd-field pulses is counted so as to be compared with the number of H sync pulses of the composite video signal. The number of H sync pulses fed to the character generator (31) is reduced by the number of detected odd-field pulses thereby smoothly naturally moving or scrolling displayed characters vertically starting from an odd field. A given number of character lines are displayed simultaneously with remaining lines being concealed by an electronic window (a) formed in response to the window pulse generator (54), and character data is rewritten, by the rewrite pulse generator (45) responsive to the shift pulse generator (44), such that data of character lines pushed out of the window (a) is erased and data of a new line is added.

In a process for producing a surface remelted chilled layer camshaft by using a high density energy irradiation and self-cooling, a cam is rotated around the center axis of the camshaft and a position of a torch for the irradiation (e.g., a TIG arc torch) is controlled so as to form an angle between a tangential line of the cam surface and a horizontal line at a melting position in a lower side of the horizontal line in a direction opposite to the camshaft rotation direction being from 30.degree., preferably 20.degree., to zero degree.

In an audio output terminal device, a buffer control unit adjusts the buffer size of a jitter buffer in accordance with the setting of a sound output mode instructed in an instruction receiving unit. If the instruction receiving unit acknowledges an instruction for setting an audio output mode that requires low delay in outputting sound, the buffer control unit reduces the buffer size of the jitter buffer. Further, the buffer control unit controls, in accordance with the instructed setting of the sound output mode, timing for allowing a media buffer to transmit one or more voice packets to the jitter buffer.

This invention relates to a graphic tactile cell for indicating a graphic pattern, in which the arrangement of the tactile surface can be enlarged easily. This graphic tactile cell includes tactile pins for indicating a graphic pattern by vertical movement, piezoelectric element segments which are bent upon application of a voltage to vertically drive the tactile pins, and a unit base for holding the tactile pins and the piezoelectric element segments. A plurality of cell units each including a unit number of tactile pins, corresponding piezoelectric element segments, and a unit base for holding the tactile pins and the piezoelectric element segments are coupled vertically and horizontally such that the tactile pins are arranged at an equal interval in vertical and horizontal directions. Proximal ends of the piezoelectric element segments are held by the unit base through plastically deformable adjusting members.

A process for producing a camshaft with cams include the steps of forming a surface hardened layer in each of the cams by a remelting chilling treatment using high density energy (e.g., a TIG arc), characterized in that after the remelting chilling treatment, the camshaft is cooled by passing a cooling medium through a through hole formed longitudinally in the camshaft. As a result of the cooling, the neighboring untreated cam has a temperature of up to 250.degree. C. Elongation of the camshaft due to thermal expansion is so small that no melt-down end portion defects appear.
