Thus read image signal is subjected to sample-and-hold by a sample hold circuit 11, and A/D- converted 12. Thus converted image data is written in the address of a semiconductor memory 13 designated by an address signal from the generator 14 synchronizingly with a write pulse. In such a way, the output timing of an image data can be adjusted. Therefore, since the read cycle of an image can be made longer than the time of write in the memory 13, above-mentioned purpose can be accomplished.

IPC: H01H50/30
Filed: 1982-07-07
Abstract: The transducer comprises an armature and a core. Both pieces are E-shaped, and their geometrical dimensions are chosen so that when their central legs come into mutual contact, air gaps still exist between both pairs of outer legs where these face each other. A coil bobbin is fixed to the core and forms a straight guide for the central leg of the armature. The frontal surfaces of the outer legs are chamfered so that the limiting surfaces of the air gaps are inclined with respect to the travel direction of the armature. In order to minimize the hum, a short-circuit ring is embedded into the central leg of the core.

Abstract: PURPOSE:To carry out the competition control for the internal and external request signals with use of no delaying circuit, by controlling the generation of the internal request signal of a refresh, etc. plus the memory start based on the internal request signal by means of a clock whose pulse width is freely controlled. CONSTITUTION:The internal request signal and the start signal of a refresh, etc. are generated via a flip-flop FF1, an NOR circuit NOR, an FF3 and an NAND circuit NAND through synchronizing with the front and rear edges of a pulse, whose width is freely controlled, povided from an oscillator OSC. While, in the time when the external request signal is preceded than the internal request signal which is applied to a competition control circuit, the write-in/readout cycle period signal RWCY is generated from a timing producing circuit in accordance with the write-in/readout start signal provided from an FF2. At the same time, the start signal of a refresh, etc. is inhibited during this period via the gate NAND to control the competition of the internal and external request signals. Accordingly the pulse width provided from the oscillator OSC is controlled in accodance with a period during which the write/ read starting signal is generated and then the signal RWCY is generated to eliminate a delaying circuit.
