Title: Frequency control circuit
Inventor: KANEKO SHINJI
IPC: H04N9/896
Filed: 1978-04-20
Abstract: PURPOSE: To obtain the signal without phase shift, by adjusting the phase of the output signal of  the frequency demultiplier which obtains the frequency corresponding to the chroma subcarrier  frequency with the output of the frequency demultiplier obtaining the frequency of 1/n.   
     CONSTITUTION: When the reproduced horizontal synchronizing signal is missing from the two  rotary magnetic heads, discrimination signal is obtained from the terminal 8a of the phase discrimination circuit 8, it is inputted to the frequency demultiplier 2 via the OR circuir 9, and the  counter is reset. In this case, no signal is obtained at the terminal 8b and no signal is fed to the  sampling hold circuit 11 of the phase comparator 3. Accordingly, the output not affected to the  phase shift is obtained from the frequency demultiplier 2. Consequently, from the variable frequency oscillator 1, the signal n times the frequency approximately equal to the horizontal synchronizing frequency is obtained. Further, the output of the frequency demultiplier 2 dividing the  frequency of the oscillator 1 by 1/n, is fed to the frequency demultiplier 5 dividing the output  of the frequency demultiplier 2 by 1/m. Thus, the switch circuit 13 is turned on once at the m  horizontal period to regulate the phase of the output signal of the frequency demultiplier 4 dividing the output of the oscillator 1 by 1/m.

Title: Charge coupled device
Inventor: KAGAWA KEIICHI
IPC: H01L29/762
Filed: 1978-04-20
Abstract: PURPOSE:To prevent the practical increment of electrode length in the transfer direction conversion part to improve a transfer efficiency by dividing the transfer electrode in the width direction and performing transfer for every divided part. CONSTITUTION:N<+> channel stop 9 is provided on p-type Si substrate 20, and gate electrode 22 such as Al is provided through SiO2 21. Layer 23 is a potential well. Thus, when width W of electrode 8 is devided by channel stop 9 to make the width of divided electrodes equal to electrode length L, the deterioration of a transfer efficiency is not generated because the practical electrode length in the transfer direction is equal to L, for example, between electrodes a11 and a12 and between 122 and a23. By this methode, the charge injected to 8 passes through a long transfer stage and is outputted to 10, and the transfer time is not shifted due to the same channel length in case of the even number of floding times. Since the channel is analyzed in the direction vertical to the transfer direction in this manner, the transfer capacity is not changed in the direction conversion part of multistage CCD formed zigzag, and no complicated-structure electrode and diffusion layer are required, and the transfer efficiency and the transfer time are improved.
