Title: Method and device for fetching image
Inventor: NISHIYAMA KIYOHARU
IPC: H04N5/907
Filed: 1992-06-16
Abstract: PURPOSE:To fetch image data in the state set with plural images in one memory by contracting and fetching an external video signal to a specific position of a memory and storing data in the area other than already fetched specific area. CONSTITUTION:An input video signal is converted into a format to be inputted to a multi-port video RAM 1 by a video signal processing circuit 8. When a frame pulse is inputted through a frame pulse generating circuit 7, a memory controller 2 successively increases and generates a raster address synchronously with a horizontal synchronizing signal inputted. On the other hand, a SAM part in a RAM 1 fetches a digitized video signal synchronously with a serial clock. After fetching data in a prescribed period in one raster, the controller 2 outputs a write transfer pulse to the RAM 1 to fetch the data of the SAM part to a RAM part. This operation is repeated for one frame in each horizontal synchronizing signal to fetch the data of frame to the RAM 1.

Abstract: PURPOSE:To improve the reliability of a component even at the time of flowing a faulty current such as short-circuiting a load by providing a circuit clamping a gate-emitter of the component in a way that the gate-emitter voltage does not exceed the absolute maximum rating of the component. CONSTITUTION:Constant voltage diodes ZD1, ZD2 are provided between the gate and emitter of an electrostatic induction type self extinction component 1 and a gate-emitter voltage VGE at fault current is clamped to the Zener voltage. The Zener voltage of the diode ZD1 is selected over the absolute maximum rating of the gate-emitter voltage of the component 1. Moreover, since the diode ZD2 is connected in series, it is required to select the Zener voltage of the diode ZD1 lower by the forward voltage drop of the diode ZD2. Thus, the gate-emitter voltage of the electrostatic induction type self extinction component is clamped to the specified voltage at fault current such short-circuit of load and the positive feedback effect of the component is prevented thereby suppressing the increase of current at the time of short-circuiting and improving the reliability of the component.

Abstract: PURPOSE:To miniaturize a contact and secure contact reliability by setting the downward force of the pressing contact larger than the upward force with a lift spring, pressing an electric component terminal while compressing the lift spring so that the pressing contact is slid along the surface of the electric component terminal. CONSTITUTION:When the pressing force of a contact switching member is released after an electric component 3 is mounted, a spring section 7 is recovered, a pressure receiving section 9 lifts the contact switching member, and a pressure contact section 10 is displaced forward and pressed into contact with the surface of the bend section 4a of an electric component terminal 4 from the lateral direction. The spring section 7 is elastically recovered continuously after the pressure contact, thus the contact section 10 applies the downward force larger than the upward force by a lift spring 17 to the terminal 4 and electric component 3. A pressing contact 5 compresses the lift spring 17 and presses the electric component 3 and terminal 4 to the position a2 from the position a1, the contact section 10 of the pressing contact 5 maintains the pressure contact with the terminal 4 and is slid to the position b2 from the position b1, and a metal face is exposed to attain the healthy contact.
