Title: Magnetic recording and reproducing device
Inventor: TAKAHASHI TOORU
IPC: G11B15/665
Filed: 1983-07-25
Abstract: PURPOSE:To perform the composite photographing and at the same time to prevent a malfunction without providing a video record locking switch by discriminating the position of a mode setting cam when a power supply is turned on and turning the cam to a stop mode position in the modes excluding the stop mode. CONSTITUTION:The turning position of a mode setting cam 1 which can set plural types of modes is detected by photosensors 7 and 8 and switches 9 and 10. The stop signal is supplied by a mode discriminating means (a). When the recording is discriminated as a temporary stop or stop mode during the application of power supply, the turning position is maintained. Then a motor 14 is driven via a control signal generating means (b) in other modes to turn the cam 1 up to the stop mode position. Thus the mode is discriminated when the power supply is turned off. In such a way, the composite photographing with no use of a video record locking switch is attained. At the same time, a malfunction is prevented for a recording/reproducing device.

Abstract: PURPOSE:To collect the gas leakage from a sealing section and prevent gas from being leaked externally by forming a sub-gas chamber between a gas cham ber outer cylinder provided at the outside of a hollow rod and the hollow rod and connecting the sub-gas chamber to a main gas chamber. CONSTITUTION:A hollow rod 8 is inserted in a cylinder 1 so as to freely slide and a damping force generation mechanism 12 is provided at the lower part of the rod 8 between hydraulic pressure 2 and 9. In addition, a gas chamber outer cylinder 35 is concentrically provided at the outside of the rod 8 and a sub-gas chamber 36 is formed between the gas chamber outer cylinder 35 and the rod 8. This sub-gas chamber 36 is connected to a main gas chamber 10 through a gas path 22 and a switching valve 21. Thus, even if the gas dissolved in oil is escaped from a sealing section 6, this gas is collected in the sub-gas chamber 36 and is not leaked externally. Besides, since the gas pressure of the sub-gas chamber 36 is applied to the sealing section 6 and the differential pressure of the sealing section 6 is small, a suspension unit with low pressure resistance is required.
