IPC: G11C11/409
Filed: 1990-02-28
Abstract: PURPOSE:To shorten the data read time even in the case of the increase of the capacity by providing a switching circuit which transmits the output signal of a differential amplifying circuit to first and second data lines and a data amplifying circuit which amplifies the difference potential between first and second data lines. CONSTITUTION:The difference potential between nodal points A and the inverse of A is made higher than that between bit lines BL and the inverse of BL by the gain of a differential amplifying circuit 3. Therefore, the enable timing of a selective signal TSW to turn on a switching circuit 4 is quickened to quicken the timing of generation of the difference potential between a pair of data lines D and the inverse of D and output of read data RD independently of the memory capacity. Thus, the data read speed of a memory cell 1 is increased even if the amplification speed of the difference potential between the pair of bit lines BL and the inverse of BL in a sense amplifying circuit 2 is the same. Thus, the data read time is shortened even if the memory capacity if increased.

Title: Combined emitter follower circuit
Inventor: TANAKA MINORU
IPC: H03F3/50
Filed: 1982-03-30
Abstract: PURPOSE:To eliminate the potential difference between input and output terminals, by correcting the difference of polarity between transistors TRs by a current mirror circuit which is provided between the input-side TR and the output- side TR. CONSTITUTION:The collector current flowed to a PNP TR12 is flowed to a current mirror circuit consisting of a diode-connected PNP TR15 and an NPN TR 18. Since the emitter of an NPN TR16 operating as an emitter follower in the output side is connected to the NPN TR18, currents flowed to TRs 12 and 16 for no-signal are equal to each other approximately. The difference between currents flowed to both TRs is the difference of polarity. As the result, since the voltage between the base and the emitter of the TR16 and the voltage between the base and the emitter of the TR12 are equal to each other, the potential difference between input and output terminals is cancelled.

Title: Memory sharing system
Inventor: GOTO TETSUO
IPC: G06F9/52
Filed: 1986-03-10
Abstract: PURPOSE:To improve processing capability by deciding >=1 preferential CPU out of a CPU group and performing the time division control of a common memory in synchronizing with the working of said preferential CPU. CONSTITUTION:A CPU 91 is defined as a preferential CPU and the states are successively allocated to CPUs 91-94 in synchronizing with the basic working clock of the preferential CPU. A synchronism control circuit 50 of a time division control part 5 has a function to allocate the next state to the CPU 91 after an access request given from the CPU 91 is detected. The part 5 is synchronized with the CPU 91 and therefore the changing point of the time division state is always coincident with the time point where the external request of the CPU 91 is produced. Then the changing point of the time division state is also equal to the replaceable time point for the accesses given from the CPUs 91-94. Thus a shared memory 412 accepts the access given from any CPU. As a result, the CPUs 92-94 are never affected even in case the circuit 50 suddenly allocates the next state to the CPU 91.

Abstract: PURPOSE:To exhibit a cleaning capture effect and an inertia force capture effect, prevent the re-scattering of captured dust and decrease energy loss by spreading or flowing liquid in the dust capture part of an element. CONSTITUTION:A curved air passage 1 is made by combining elements which are trough-shaped and have an H-shaped cross section, water is flowed along the inner surface to the inside of the lower part of the side plate 2 of an element to make a water screen 3, and the water is received by the channel part 4 of the dust capture part of the lower part of the side plate 2. Also, water is spread on the upper surface of the horizontal plate of the element of another dust capture part. Although air containing dust flows changing the direction sharply at the curved part 6 in the upper part of the air passage 1, the dust, which has large density and centrifugal force, can not make a sharp change of the direction, hitting the lower surface of the horizontal plate 5 of the curved part 6. A part of the dust drops on the upper surface of the horizontal plate of the lower element and is captured by the water screen 3 which is formed there. In this way, dust can be discharged efficiently.
