IPC: G03B5/00
Filed: 1993-10-15
Abstract: PURPOSE:To execute excellent distortion correction and to obtain a natural video image by taking a prescribed phase relation between a fetch timing of correction data and a fetch timing of video data in response to a state of an optical system being a basis of correction processing. CONSTITUTION:An undesired charge is discharged with an undesired charge discharging pulse S after a transfer pulse T is sent in response to a vertical synchronizing signal V. The undesired charge is discharged for a period A and the charge is stored for a period B and optical information is fetched. Furthermore, the information is transferred and written into a memory for a period C and the information is read from the memory for a period D and a zoom coefficient S is set in the timing of the vertical synchronizing signal. That is, the optical information obtained for the period B is read from the memory with a delay by one pattern and the coefficient is set. Then focal distance information of the optical system is fetched in a prescribed timing for the charge storage period and a read address generating section sets a timing of providing the zoom coefficient S at the start of reading a picture signal to attain excellent distortion correction and to obtain a natural video image.

Title: Signal detector for coil
Inventor: IKOMA MITSUGI
IPC: F24F11/02
Filed: 1985-11-20
Abstract: PURPOSE:To maintain a contact reliability, by making an electrical signal for preventing poor contact overlap on a signal from a coil for a contactor connected to a coil to allow defective conduction due to insulating material attached to the connector to be neglected. CONSTITUTION:As a magnet 1 turns, a signal current generated by a coil 2 is inputted into a signal input unit 4 and the rotation of the magnet is detected. At this point, a current in which the said signal current is combined with a current run from a voltage source 6 flows through a connector 3. Therefore, even when the current induced in the coil 2 is small, a relatively large amount of current flows to the connector 3. This can help avoid the effect due to any defective conduction caused by the attachment of insulating object in the connector 3.
