Title: Digital logic circuit device
Inventor: NARAHARA KOICHI
IPC: H03K19/08
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To realize an ultrahigh speed operation by connecting a circuit element matching a signal propagation speed in at least two electrode transmission lines so as to match a characteristic impedance of each electrode transmission line to each input output terminal. SOLUTION: A drain electrode T1, a gate electrode T2 and a source electrode T3 of a travelling wave transistor(TR) have respectively a specific characteristic impedance and a specific propagation constant. An input terminal Din and an output terminal Dout are connected to circuit elements having an impedance coincident with or close to the characteristic impedance of the drain T1. Similarly terminals Gin, Gout, Sin, Sout are connected to circuit elements having an impedance coincident with or close to the characteristic impedance of the gate T2 and the source T3. Waveform deterioration is suppressed by making at least two propagation constants of the T1, T2, T3 in matching with each other to realize an ultrahigh speed operation.

Title: Electric fan
Inventor: SHIMADA SADAHIRO
IPC: F04D29/44
Filed: 1984-10-18
Abstract: PURPOSE:To lessen noises by grouping air passages in a pair of two at the back of an air guide, providing air passages in a double of blade number for reversing the phases of non-dense waves coming out of one air passage and those out of another air passage for their cancellation. CONSTITUTION:A connection passage 33 to an air passage 31 is continuous to another air passage 37 directed toward the inside of an air guide 30 and divided by a guide vane 38. The air passage 37 is arranged in a pair of two and comprises eight groups, joining to each other at their internal end 39. Consequently, non-dense waves of air pass through the inside of each air passage 31 with the rotation of an impeller 21. The number Z of the air passages is set to sixteen and the number Z2 of blades 23 of the impeller 21 set to eight, respectively. When dense waves enter in a primary air passage 31, therefore, non-dense waves enter in its adjacent air passage 31 and dense waves in another adjacent air passage 31. This flow of dense and non-dense waves occurs alternately in the air passage 31. The flows of each air join together at the internal end 39 and dense and non-dense waves cancel each other, thereby making it possible to lessen noises.

Title: Coining machining for dynamic pressure bearing
Inventor: OKAZAKI YASUTAKA
IPC: F16C17/04
Filed: 1991-08-30
Abstract: PURPOSE:To mold a dynamic pressure generating groove with a preset depth while the flatness of a work after the coining process is completed is kept within 1mum by using 80% of the pressing force required to obtain the preset groove depth by one pressing, and repeating the pressing many times. CONSTITUTION:A work 3 is pinched and pressed by a punch 1 and a die 2, and the irregular shape on the surface of the punch 1 is transferred to the work 3. In this technical means, the pressure for machining the work 3 is reduced to 80% of the pressure required to obtain the preset groove depth by one pressing, and the pressing is repeated many times. When the pressing force is gradually decreased from this pressing state, the contact area between the punch 1 and the work 3 is gradually decreased. A dynamic pressure generating groove with the preset depth can be formed while the flatness of the work 3 after the coining process is completed is kept within 1mum.

Abstract: PURPOSE:To obtain a sufficient damping effect by providing an inductor element between a constant voltage circuit and a constant current circuit so as to suppress sufficiently oscillation or ringing even when a signal bypasses through a constant voltage source or a potential of an input signal is low. CONSTITUTION:An output of a constant voltage source comprising a resistor 11 and a Zener diode 12 is connected to a base of a transistor(TR) 3 via an inductor element 3. A current flowing to loads 8, 9 is kept constant by the potential.
