Patent JP-H098623-A (JP)
Title: Output circuit
Inventor: WATARAI SEIICHI
IPC: H03K17/567
Filed: 1995-06-15
Abstract: PURPOSE: To accelerate communication by providing 2nd and 3rd inverters and a 3rd MOS transistor, for which the output terminal of the 2nd inverter is connected to a gate and parallelly connected with a 1st MOS transistor. CONSTITUTION: While the change of a transistor Q1 from ON to OFF is controlled by the delay time of inverters I1 and I2, two paths respectively passing through transistors N1 and N3 exist as a current path from an output terminal to the base of the transistor Q1. With a current to pass through these two paths, two currents i1 and i2 to be timewisely changed corresponding to the delay time of the respective inverters I1 and I2 are applied to the base of the ransistor Q1. Therefore, the ON state of the transistor Q1 is controlled by the change of the currents i1 and i2. Thus, since the ON state of the transistor Q1 is suitably controlled, the generation of linking of an output signal VO caused by a parasitic circuit can be suppressed.

Title: Decontamination method
Inventor: TAMAGAWA TADASHI
IPC: G21F9/28
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a decontamination method having high crud dissolving power, capable of reducing corrosivity to a metallic material and being excellent in workability by dissolving/removing metallic oxide sticking in a nuclear reac tor cooling water system by using a reducing acid solution by setting a specific concentration oxalic acid solution containing hydrazine to a specific pH value. SOLUTION: A reducing acid solution (a reducing decontamination agent) is adjusted to pH 2 to 3 by adding hydrazine to a low concentration oxalic acid aqueous solution having the oxalic acid concentration of 0.05 to 0.3 wt.%. Crud dissolving power lacks when the oxalic acid concentration is less than 0.05 wt.%, and corrosivity increases when the concentration exceeds 0.3 wt.%. The crud dissolving power lacks when pH of the reducing decontamination agent is larger than 3, and the corrosivity increases when the pH is smaller than 2. A temperature when dissolving iron oxide by using such a reducing decontamination agent is suitably about 80 deg.C or more. Thus, since the oxalic acid concentration is low and hydrazine is contained as well, while the corrosivity is relieved, reduction in dissolving power can be compensated by the dissolution promoting action by increasing the pH.

Title: Karman's vortex flowmeter
Inventor: KASHIMURA OSAMU
IPC: G01F1/32
Filed: 1993-06-22
Abstract: PURPOSE:To prevent lowering of measurement accuracy in connection cables between a sensor and a detection circuit of Karman's vortex clue to external vibration. CONSTITUTION:A coaxial cable 30 consists of inner conductor of stranded cable 31, a dielectric 32, outer conductor of side wound shield 33 and a protection clad 34.

Title: Pole for lens movement of camera or the like
Inventor: MIURA SHIZUO
IPC: G02B7/02
Filed: 1982-08-26
Abstract: PURPOSE:To prevent the generation of moire even when a pole which guides the movement of a lens in a lens barrel in optical-axis directions is arranged in the optical path of the lens barrel by recessing the outer circumference of the pole into light-shielding grooves. CONSTITUTION:The light-shielding grooves 15 which are nearly V-sectioned and have a specific angle alpha are formed at specific intervals P in the overall-length outer circumferences of poles 3-5 which are arranged in the optical psth of the lens barrel 1A of a zoom lens and slide and guide lenses 6 and 11 along the optical axis L. When a cam cylinder is rotated around the optical axis L to move the lenses 6 and 11 to wide-angle or telephoto positions for photography, for example, intense light l1 is made incident to the optical path and when it strikes the lower pole 5, part of it strikes the peak of a mountain part and the remainder strikes a slanting surface of the V-shaped light-shielding groove 15; they are reflected respectivery, but the reflected light l'1 (l''1) is weakened to eliminate the influence upon photographic light, preventing the generation of moire on the picture plane of a film surface 19.

Abstract: PURPOSE: To make a subsequent polishing process simple by a method in which in advance of the application of a repairing paint, the surface of a repair part is wetted with one or more kinds of organic solvents selected from specified ester-type and ether-type organic solvents. CONSTITUTION: In a repairing method in which the repair part of a crosslinked clear paint film is sanded and coated with a repairing paint, in advance of the application of the repairing paint, the surface of the repair part is wetted with one or more kinds of organic solvents selected from ester type organic solvents with a boiling point of 200-250 deg.C and ether type organic solvents with a boiling point of 200 250 deg.C. In this way, the wettability of the repairing paint improves so that the applied paint can spread thinly. After the application, the paint film is crosslinked in conditions according to the composition of the paint. After curing, the difference in the evenness from an unrepaired part is eliminated as necessity requires, or the repaired part is polished for glossing.

Title: Method for preventing formation of macrocrystalline compound in al-zn-mg based alloy
Inventor: YOSHIKAWA KATSUYUKI
IPC: C22F1/053
Filed: 1993-06-22
Abstract: PURPOSE:To prevent the formation of a macrocrystalline compound, deteriorating the strength, ductility, toughness, fatigue strength, etc., of an alloy, in a structure by controlling molten metal cooling conditions at the time of casting an Al-Zn-Mg based alloy to which Ti and Zr are added. CONSTITUTION:Elements, such as Ti and Zr, are added in order to improve the strength, stress corrosion cracking resistance, and weldability of an Al-Zn-Mg based alloy. At the time of casting a molten metal of this Al alloy by semicontinuous casting, etc., cooling conditions are controlled so that cooling passing time ta through the region between the formation temp. of (Ti, Zr) Al3 macrocrystalline compound and the eutectic temp., at which alpha-Al crystallizes out, satisfies inequality I and also the formation temp. Tz of the (Ti, Zr) Al3 macrocrystalline compound is determined from equation II, in order to prevent the formation of the (Ti, Zr)Al3 macrocrystalline compound causing cracking at the time of working, such as rolling extrusion, and casting, of a casting. By this method, the casting of the Al-Zn-Mg based alloy can be carried out without forming the (Ti, Zr)Al3 macrocrystalline compound even in the case of Ti and Zr concentrations exceeding the equilibriously determined primary crystallization curve.

Abstract: PURPOSE: To previously prevent an erroneous photography by making the automatic focus control device inoperative or its equivalent state in interlocking with the change action to the range of macro photographing.  
     CONSTITUTION: In the zoom range, contacts 21a and 21b of switch SW21 are ON while contacts 21b and 21c are OFF. Here if the release is pulled, SW22 is ON with interlocked therewith so that the drive system 8 and operation processing circuit 11 are energized to make respective circuits work, the circuit 11 is provided for the purpose of automatic focus detection. In this state and further, automatic- manual change member 7 is maintained as such, and if zoom lever 4 is operated, SW20 becomes OFF, hence, though the release 6 is pulled, the drive system 8 is not energized so that the picture is not taken. At this time, the member 7 is placed at the manual position, namely, the contacts 21b and 21c are made ON to energize the drive system 8, then it is possible to take the picture. Accordingly, the failure due to misoperation in taking the picture can be previously prevented.
