Filed: 1987-10-05
Abstract: PURPOSE:To accelerate read speed by increasing the initial read current of memory cell selection which the change of an address signal is detected, simultaneously reducing this read current after a prescribed time and accelerating the bit line charging speed of initial read. CONSTITUTION:A device is constituted by a change detecting means 3 detecting the level change of the address signal, a holding means 4 holding the detected result of the means 3 at least until the potential of a word line is pulled up to prescribed high level potential and an operating means 5 operating the current quantity of a prescribed constant current source 2 in an increasing direction while the change of the address signal is held by the means 4 at read time. Then, the read current at the read time is adjusted to be large at first and to be small after that. Therefore, the word line at the read time is charged at high speed and simultaneously accumulated charge quantity in the memory cell 1 is controlled by the small read current after that. Thus the read speed and write speed can be accelerated at the same time.

IPC: G03B9/24
Filed: 1985-11-09
Abstract: PURPOSE:To obtain a device having the open/close characteristic which approximates an ideal characteristic very much, by providing an inertia ring independently of an open/close ring and turning the inertia ring to interlock the inertia ring and an open/ close plate with each other so that the inertia ring is rotated integrally only for turning in the shutter opening direction. CONSTITUTION:When a current is not applied to a coil 22, an inertia ring 16 is turned on the direction of an arrow (a) by the force of a tension spring 29 and an interlocking pin 24 is clipped between a notch 26 and the end part of a turning range control aperture 25. At this time, a shutter aperture formed with shutter blades is closed. When a current is applied in the shutter opening direction in this state, the shutter aperture formed with shutter blades is opened by the electromagnetic action of a magnet 23. When an open/close plate 15 is turned in the shutter opening direction, the interlocking pin 24 pushes the end part 26a of the notch 26 to turn the inertia ring 16 together. Consequently, since the inertia ring 16 is turned together by the turning energy of the open/close plate 15, the opening speed of the shutter is made lower and is set freely by setting the mass of the inertia ring 16 and the force of the tension spring 29.

Abstract: PROBLEM TO BE SOLVED: To prevent a shock caused by tying up by limiting or stopping a boosting value or boosting control based on the generation of tying up when hydraulic pressure in the releasing side friction engaging device of a clutch to clutch speed change is temporarily boosted after the hydraulic pressure of the engaging side friction engaging device is increased. SOLUTION: The possibility of down shifting from a third to a second speed is determined (step 12). If the determination is positive, tying up detection is performed (step 13). Then, the generation tying up is determined (step 14) and if the determination is positive, the re-boosting amount of a second brake as a friction engaging device in a releasing side is reduced according to the amount of tying up (step 15). Further, the hydraulic pressure of the second brake in the releasing side is learned and controlled (step 17). On the other hand, if the determination of the generation of tying up is negative, the generation of shock at the end of speed changing is determined (step 18) and if its generation is determined, the control amount of the re-boosting control of the second brake in the releasing side is increased (step 19).
