Title: Consecutive recording device of vtr
Inventor: HIDA SHIYUUICHI
IPC: G11B27/024
Filed: 1984-05-14
Abstract: PURPOSE:To prevent a double recording part in case of consecutive recording by providing a means which makes rewinding impossible for a prescribed period when consecutive recording from the reproducing mode to the recording mode is detected by a discriminating means. CONSTITUTION:In case of consecutive recording from the reproducing mode to the recording mode, a mode discrimination pulse is generated in an AND gate 8, and an output is generated in a DFF11, and three reference pulses having the same period as a pulse CTL are permitted to pass through an AND gate 12. An output is generated from an OR gate 14, and during this period, a transistor TRTr15 is turned on to make the output of a servo circuit 21 ineffective. A counter 20 counts three false CTL pulses. Meanwhile, the output of the gate 14 goes to the low level, the TRTr15 is turned off, and the output of the circuit 21 rotates a capstan motor 22. The motor 22 is reversed by the output from a microcomputer 23, and pulses detected by a CTL head 17 are sent to the counter 20, and the motor 22 is reversed until the sum of these pulses and three preliminarily counted pulses is 15, and thereafter, the mode is switched to the recording mode.

Inventor: OBAYASHI FUMIO
IPC: H05G1/34
Filed: 1985-05-08
Abstract: PURPOSE:To enable accurate X-ray photographying by comparing the output from a tube voltage regulator in step with different referential levels to display the setting voltage then varying the display with correspondence to the setting level of tube current to promote re-setting and latching the correct setting level of tube voltage. CONSTITUTION:The output from a tube voltage variable regulator 7 is fed through a rectifier circuit 15 to a comparator circuit 12 where it is compared with referential voltage in step to control lighting of LED L1-L4 through a transistor circuit 21 in display circuit 20 thus to display the setting voltage. Then the tube current is set through a tube current setting circuit 22 and if the setting level is high, a transistor Tr in shortcircuit 18 is turned on to change the lighting conditions of the elements L1-L4 thus to promote resetting of tube voltage. Consequently, the tube voltage having high setting tube current and voltage drop for regulating the regulator 7 in voltage increasing direction is corrected and latched by latching circuit 13. As a result, correct tube voltage and current are set at anytime resulting in accurate X-ray photographying.
