Title: Stop control method for camera
Inventor: HIRAIKE FUMIAKI
IPC: G03B9/02
Filed: 1980-07-28
Abstract: PURPOSE: To control stop value highly accurately by calculating the operating distance of a movable stop member, and starting the stopping of the stop upon arriving of the stop member in the position forward by said distance than the stop value position.  
     CONSTITUTION: First, the position and speed of a stop member are detected. For example, in the case of detecting a stop value from the number of pulses, the position is detected by measuring the quantity of pulses. If the number of pulses entering in a certain constant microtime δt is defined as (n), a velocity (v) is determined by v=Kn/δt (K=constant). The distance Δl at which a stop member moves since starting of operation of a stop operation stopping member until stopping of the stop member is determined by the equation I if the operation time of the stop operation stopping member is defined as Δt. The preset moving distance δL of the stop member is determined by the equation II. Hence, the timing for starting the operation of the stop operation member is known as the timing of the arrival of the stop member at the position forward by δl from the preset position. With such constitution, the stop value is controlled with high accuracy.

Title: Double speed reproducing circuit
Inventor: SOTOGUCHI AKIRA
IPC: H04N5/93
Filed: 1986-05-07
Abstract: PURPOSE:To attain the double speed reproduction in which a horizontal synchronizing period is constant and a noise bar does not exist by storing a reproducing video signal without the noise bar into a field memory with a horizontal synchronizing signal as a counting input while a sub-head is reproduced and scanned. CONSTITUTION:A field memory 9 executes alternately a storing and a reading at the time of the double speed reproduction. A reading address executes the reading in the sequence of the memory information of the field memory 9 until an RF switching pulse is supplied. The output of both reading counters 21 and 22 is inputted to the first changing-over circuit 23 and alternately selected by a changing-over clock. Since the second writing counter 15 is reset by a vertical pulse and the reading counter 22 is reset by the RF switching pulse, a vertical synchronizing signal is read by the head output changing-over timing of the reproducing video signal. Thus, a reproducing picture is changed over at a frame period, a switching area is formed in the sequence of the time series from the top and an easy-to-see double speed reproducing picture is formed.
