Title: Sense amplifier
Inventor: NISHIMATSU HIDEO
IPC: G11C11/419
Filed: 1988-08-09
Abstract: PURPOSE:To enlarge the output amplitude of a sense amplifier and to improve the action margin of a memory by connecting an output potential pull-down circuit between a pair of output nodes. CONSTITUTION:The title amplifier is composed of an N channel MOS transistor Q5 in which a source is connected to a Vss power source node and a drain and a gate are connected to output nodes N1 and N2 corresponding to respective ones and in the same way, an N channel MOS transistor Q6 in which the source is connected to a Vss power source node and the drain and the gate are corresponded reversely to outputs N1 and N2. For example, when the N channel transistor is used for the pull-down and one side out of a pair of output nodes is higher than the pull-down power source potential, one side transistor for pull-down in which the potential of one side output node is guided to the gate becomes an ON condition and the potential of other side output node is pulled down. Thus, the output amplitude of the sense amplifier can be drastically enlarged and the action margin of the memory can be improved.

Title: Driving circuit for static bus
Inventor: KOIKE JUN
IPC: H03K19/096
Filed: 1989-07-31
Abstract: PURPOSE:To quicken the transmission speed with precharge of a static bus by precharging the static bus in a timing when an output buffer connecting to the static bus does not drive the static bus. CONSTITUTION:A static bus 1 is driven by a tri-state output buffer 3 by using an output buffer control signal B generated by a control circuit 8. This is because an undesired bus output is suppressed to form a precharge timing till a succeeding clock signal phi1 rises after a data is outputted to the static bus 1 with the output buffer control signal control circuit 8 and the data is latched, that is, after the rise of a clock signal phi2 representing the time of end of latch. Since precharge is implemented in such a way, no delay is caused in the low level transmission on the static bus.

Title: Measurement of flow rate of granular solid flowing through transport tube
Inventor: SHIMADA KATSUHIKO
IPC: G01F1/74
Filed: 1982-11-15
Abstract: PURPOSE:To compute the flow rate of a granular solid at a high accuracy even when the granular solid is a fine particle and low in the density by measuring drop in the pressure of a solid-gaseous 2-phase fluid with a differential pressure meter provided at a part greatly changing in the flow velocity thereof with the reduction of the tube diameter in the course of a transport tube. CONSTITUTION:The diameter of a transport tube 1 is reduced to form a small diameter section 1' at a part thereof 1 and a differential pressure meter 4 is provided at the small diameter section 1'. Drop in the pressure of a solid-gaseous 2-phase fluid is measured at the smaller diameter part with a differential pressure meter 4 and the flow rate of the granular solid flowing through the transport tube 1 is computed with an arithmetic unit based on the measured value. The velocity of air and the granular solid varies greatly immediately after the reduced diameter of the transport tube 1 (non-normal flow area). This enhances variation in the mixing ratio by weight (m) of air and the granular solid with respect to the pressure drop ratio alpha. Thus, the flow rate of the granular solid flowing through the transport tube 1 can be measured at a high accuracy even when the granular solid is a fine particle and low in density.
