Title: Low-power consumption redundancy circuit for memory element
Inventor: YON FUN OO
IPC: G11C29/00
Filed: 1991-02-25
Abstract: PURPOSE: To make a memory element low power consumption by utilizing a test signal having a short pulse width and latch back MOSFETs to reduce the power consumption of the redundancy circuit in a memory element. CONSTITUTION: In a state in which the fuse of a redundancy operation fuse circuit 47 is cut off and a redundancy circuit is used, input signals (the inversion of ϕEN, ϕEVAL) become high levels. Consequently, since a MOSFET 50 is turned ON and a MOSFET 49 is turned OFF, an output SPARE becoming a redundancy column decoder adjustment signal maintains a low state. Next, when the signal (the inversion of ϕEN) transits to the low state and, next, the test signal ϕEVAL transits to the low state, the FET 49 is turned ON and the FET 50 is turned OFF and a current is made to flow through the output SPARE from a power source. In this case, since unnecessary power consumption is generated only in a section equivalent to the width of the signal ϕEVAL, the power consumption of the circuit is reduced.

Title: Semiconductor integrated circuit
Inventor: EINO MASANAO
IPC: H03K19/0948
Filed: 1990-02-09
Abstract: PURPOSE:To acquire the H-level of an output signal after the change of an input signal at high speed by connecting a P channel transistor(TR) in parallel with an N channel TR, and providing a capacitor between its gate part and the input signal line of a circuit, and connecting a gate input part to the drain part of the P channel TR. CONSTITUTION:Immediately after the input signal of an inverter 2 changes from H to L, since the potential of the gate input part of the P channel TR 3 falls by the capacitor 5, and the P channel TR 3 is turned ON, the potential of the output of the inverter 2 rises close to supply potential. Afterwards, since the potential of the gate input of the P channel TR 5 returns from the potential extracted by the capacitor 5 to the level of the supply potential, the P channel TR 5 is turned OFF. Accordingly, the output level of the inverter 2 becomes stable at the potential obtained by subtracting Vth of the N channel TR 1 from supply voltage.

Filed: 1981-03-04
Abstract: PURPOSE:To raise the volumetric efficiency of a screw compressor by providing shaft sealing means at portions of a rotor where shafts are journaled. CONSTITUTION:Lubricating liquid supplied to grooves 34, 35 respectivly of shaft sealing means 32, 33 effects shaft sealing and sealing at the portions where shafts 11, 12 are extended through an end plate 4. Since a gas compressed to a high pressure is filled in the section of a work space near the end plate 4, a small amount of this high-pressure gas is mixed into lubricating liquid that is leaked into stepped holes 5, 6. Bearings 15, 16 are lubricated by the lubricating liquid mixed with a small amount of high-pressure gas, but the luricating liquid and high-pressure gas mixed into the lubricating liquid are separated from each other in a separation chamber 41 by the function of gravity. Here, if a recovering passage 42 is communicated to the work space when pressure in the work space is lower than that in the separation chamber 41, the gas in the chamber 41 is drawn into the work space and compressed again.
