Title: Recording and reproducing device
Inventor: SUI MASAHIRO
IPC: G11B15/18
Filed: 1984-05-29
Abstract: PURPOSE:To shift the titled device to a recording state from a recording pause state, etc. without passing through a rewinding or reproducing state, and to eliminate a time loss by making a level transition of a recording head switching signal exist in a decelerating period of a capstan motor, when shifting the device to a recording standby state from the recording state, and also disconnecting a recording current to a recording head at the same time as the level transition. CONSTITUTION:A device which satisfies a condition that a time required for a recording tape speed as a capstan motor, which reaches zero from a prescribed value is smaller than a period corresponding to about one frame of a recording video signal is used. When executing a tie-recording, it is necessary to disconnect a current in a decelerating period (during tS) without disconnecting a recording current to a head before entering a deceleration. Also, when the recording current is disconnected on the way of a track, an RF (high frequency) signal is disconnected and the track is cut off on the way, therefore, it is always necessary to disconnect the recording current after one track has been recorded. In this way, the device is controlled so as to disconnect the recording current by a level transition timing of an SWP signal (a head switching signal made by a rotary phase signal of a head drum) after the motor has been shifted to a deceleration.

Title: Switching regulator
Inventor: KAZUTOMO SHIGEAKI
IPC: H02M3/337
Filed: 1978-09-06
Abstract: PURPOSE: To obtain stable constant voltage characteristics of a switching regulator with less drive power by controlling the pulse duration by the detected output of voltage variations during on and off period of a transistor by a pulse based on the oscillated output.  
     CONSTITUTION: Since the base voltage of a transistor (Tr) Q 2  in a detecting circuit 6 is increased to lower the detected voltage Ec when the input voltage Ei is raised, the slice voltage E 1  of the collector of a transistor Q 9  is raised to shorten the on period of transistors Q 5  to Q 8 . Thus, the off period of transistors Q 10 , Q 11  controlled by the transistors Q 6 , Q 8  is shortened to thereby forcibly shut off transistors Q 12 , Q 13 . Accordingly, the oscillating frequency of the oscillating circuit 7 of a switching circuit 9 is locked to f 1  to shorten the on period of the transistors Q 12 , Q 13 . Since the output ducy ratio of the transistor T 2  is lowered, the output voltage E 0  of the terminals 4, 5 thus rectified and smoothed is lowered by the amount corresponding to the raised voltage Ei. Since it becomes reverse when the input voltage is lowered, it can obtain stalbe constant voltage.

Filed: 1986-05-15
Abstract: PURPOSE:To improve the transmission efficiency without lowering the throughput for the entire network even at the time of starting burst communication of a long length data by using control information transmitted in the 1st loop to apply communication using the 2nd loop. CONSTITUTION:Nodes 1-4 consist respectively of transmission/reception control sections 411-441 and loop switching sections 410-440 and the switch section 410 applies the connection changeover between the 1st loop 401 being an active system and the 2nd loop 402 being a standby system. In case the burst communication from the node 1 to the node 3, the node 1 sends a reservation frame of the burst communication system as control information via the loop 401 by means of the multiple address communication. Thus, the node 3 switches the loop 401 to the burst transmission/reception system and the loop 402 to the state of normal system, and the node 1, after the sending of the reservation frame, switches the loops and the burst communication is applied to the node 3. Thus, even at the burst communication of a long length data, the throughput for the entire network is not lowered and the transmission efficiency is improved.
