Title: Vertical type continuous annealing device for metallic strip
Inventor: SAKAE KUNIO
IPC: C21D9/66
Filed: 1985-04-26
Abstract: PURPOSE:To make effective use of the sensible heat of a metallic strip after annealing and to improve thermal efficiency using cyclically the cooled air or reducing atmosphere gas blown to the metallic strip after annealing. CONSTITUTION:The air or reducing atmosphere gas which is blown to the metallic strip 1 after annealing in a cooler 4 and is heated by the metallic strip 1 is recovered by a high-temp. fan 5. The recovered air or gas is fed to a preheater 6 and is blown to the metallic strip 1 prior to annealing on the inlet side of a top roll 2 to preheat the strip. The cooled air or gas is recovered by a low-temp. fan 7 and after the air or gas is further cooled by a cooler 8, the air or gas is fed to the cooler 4 and is thereby cyclically used.

Title: Interatomic force microscope with scratch mechanism
Inventor: TAKAZAWA NOBUAKI
IPC: G01N37/00
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent a probe from being contaminated and abraded and improve measurement accuracy by setting two probes to a cantilever, inclining the cantilever, applying a scratch to a sample surface by the probe at the leading side and observing the scratched surface by the other probe. SOLUTION: A scratch probe 7 and an observation probe 2 are set via a distance of, e.g. 10% to a leading end part of a cantilever 1. The cantilever 1 is inclined by an expansion, shrinkage of a piezoelectric element 3 set between the cantilever and a set stage 6. While the probe 7 is kept in touch with a surface of a sample 8, the sample 8 is moved to apply an approximately 1-2 μm scratch (flaw) to the sample surface. Then, the cantilever 1 is returned to a horizontal position and the probe 2 is set at a point of the flaw to observe the flaw. Since the clean sample surface can be observed accordingly, a change at a material surface in a liquid can be analyzed accurately.  Moreover, since the observation probe 2 and scratch probe 7 are used separately, an abrasion of the observation probe 2 or adhesion of a foreign matter to the observation probe is prevented, thereby permitting stable observation at all times.

Title: Method for setting function of portable telephone set
Inventor: KAGAMI TAKAYUKI
IPC: H04W88/02
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To maintain the kind of functions and efficiently use a memory without enlarging its capacity by preserving the prescribed functions in the memory in a compressed state, defrosting the function and preserving it in the memory at the time of using the specified function. SOLUTION: A function which is to be set in a usable state (namely, defrosting) is specified among functions compressed from an operation part 6 at present and preserved in a memory 4. A control part 3 calculates the free capacity of the memory 4 and compares it with the defrosted capacity of the specified function. When the free capacity of the memory 4 is smaller than the capacity of a defrosting function, the function to be compressed is selected from the previously defrosted functions and it is compressed/preserved. Then, free capacity is calculated again. When this processing is repeated and free capacity becomes larger than the defrosted capacity of the prescribed function, a system moves to the defrosting operation of the prescribed function. The defrosted function is preserved in the memory 4 and it is set to the usable state.

Abstract: PURPOSE:To decrease an input current by connecting >=3 series circuits consisting each of a resistor and a Josephson junction in parallel via a resistor respectively, supplying an input signal to the connecting point between this resistor and the Josephson junction, grounding the connecting points being >=3 via a Josephson junction and extracting an output from the connecting point. CONSTITUTION:A series circuit comprising a resistor R24 and a junction Ja, series circuit comprising a resistor R26 and a junction Jc and a series circuit comprising a resistor R25 and a junction Jd are provided between a line having an offset potential V-off and ground, and the series circuits are connected together via resistor R21, R22 and R23. A junction Jb is connected between the connecting point of the said resistors and ground and an output current is extracted from the said connecting point. When an input current, e.g., IA flows, the junction Ja goes to the voltage state but the junction Jb does not goes to the voltage state. On the contrary, when the input currents IA and IB flow together the sum of the current IA and offset currents iOA, iOB and iOC flows to the junction Jb, which is brought into the voltage state. Since this circuit is symmetrical to the input current IA, IB and IC, the circuit forms a 2/3 majority decision circuit.
