Title: Recording and reproducing device for video disk
Inventor: TAKEMURA YOSHIYA
IPC: H04N5/95
Filed: 1988-06-21
Abstract: PURPOSE:To halve the linear velocity (number of revolutions) of a disk by dividing a video signal into 2 channels and recording and reproducing the result. CONSTITUTION:A video signal is split into 2 channels for each line, the time axis of the signal of each channel is expanded and recorded on two tracks 37, 38.

Title: Drive method of thermal head
Inventor: IKEDA RYUICHI
IPC: B41J2/355
Filed: 1987-06-22
Abstract: PURPOSE:To prevent generation of a white line between blocks without an increase of a drive current for a printer by alternately applying a short pulse exclusively (complementarily) to two blocks when driving two adjoining blocks simultaneously. CONSTITUTION:When a pulse is applied to terminals 10-13 at such a timing of ENB 10-13, only ENB 10 passes an AND gate 4 at the time of 'H', and the signal of ENB 10 is applied as such to a terminal 8. Next when both ENB 10 and ENB 11 are set to 'H4b, a NAND gate 2 is turned ON and an output CLK of a clock generator 8 appears in an output of the NAND gate 2. The CLK passes ENB 10 through AND gate 4, and at the same time, is inverted by an inverter 5 to be applied to a terminal 83. Consequently, an enable signal is applied alternately to the terminals 82, 83 by means of CLK, so that two adjoining blocks can be heated simultaneously by a drive current for a single block and thereby generation of a white line between the blocks can be prevented.
