摘要： PROBLEM TO BE SOLVED: To provide a miniaturized voltage controlled oscillator (VCO), which can be stably oscillated, by generating a second control signal, for which the phase change component of an input control signal is corrected by changing a frequency, and positively feeding the second control signal back to an oscillation means.
SOLUTION: On the condition of matching a phase VPin of a control signal VC1 at a point A and a phase VPout of a control signal VQ2 at a point A', corresponding to the voltage level of a control voltage signal S84 supplied from a loop filter 84, the capacitance of a variable capacitance diode VC is changed. The control signal VC1 corresponding to that capacitance is supplied to an inverted amplifier 91, inverted and amplified and after impedance transformation is performed through a transistor Q2 of a phase control output part 92, a generated resonance signal fs of prescribed frequency positively fed through a SAW resonator 93 positively back to the inverted amplifier part 91. When the amplifying operation of the inverted amplifier part 91 is saturated, a control signal VQ2 of the desired frequency corresponding to the control voltage signal S84 is oscillated from the emitter of the transistor Q2 as a carrier wave fs.

摘要： PROBLEM TO BE SOLVED: To add an even scale thickness superior in adherence and to improve laser cutting by cooling the steel plate with an injection of a water stream like a curtain against a steel plate in its width direction while moving at a high temperature. SOLUTION: After a hot rolling, the steel plate 1 is reheated in an austenite threshold. The water stream like a curtain (a continuous water stream runs without cutting on the steel surface) is sprayed from a slit nozzle 4 arranged in a slit shape towards a width direction of the plate 1 against the steel plate 1. The slit nozzles 4 in a cooling zone are arranged 20 units each on the upper and the bottom face of the steel plate 1 and cool the plate from the both faces, the upper and bottom. It is desirable that all the cooling zones are of the same cooling system. A slit shape nozzle is desirable for obtaining a water stream like a curtain, but the nozzle shape is not specifically limited as long as a water stream like a curtain is obtainable on the steel plate 1 surface. A thickness of the steel plate 1 to be manufactured is desirous to be 6 mm or more wherein a generation of Fe3 O4 is easy.

摘要： PROBLEM TO BE SOLVED: To obtain the steel member having excellent fire resistance and difficult to generate a local buckling against the large compressive load acting in the case of a large earthquake even when the ratio of width to thickness is large and a stiffener does not exist by using the steel containing the specified quantity of Mo and becoming positive in the grade of the nominal stress/nominal strain within the range of the specified strain quantity. SOLUTION: This steel member is made of the steel containing, by wt., 0.05-0.70% Mo, if necessary, containing one kind or more of 0.005-0.10% each of Nb, V, Ti, and becoming positive in the grade of the nominal stress/nominal strain even in any strain quantities from the yield point to the strain quantity of 5% in the nominal stress- nominal strain curve obtained with the tension test. When the grade of the nominal stress/nominal strain becomes zero or negative, deformation is locally generated, whereby the local buckling is easily generated. Also, although the relation of the nominal stress-nominal strain in the area of small strain is important in order to restrain the local buckling, since the grade of nominal stress/nominal strain is always positive until the yield point and the quantity of strain have only to be positive within the range of up to 5%, the range becoming positive is specified to be the above range.

摘要： PROBLEM TO BE SOLVED: To obtain a steel member hardly causing local buckling, suited to steel-frame buildings, etc., and excellent in earthquake resistance by hot-rolling a steel having a specific composition containing C and Mn and then carrying out cooling at specific cooling velocity from the temp. region determined by the components of the steel. SOLUTION: A steel, having a composition containing, by weight, 0.03-0.25% C and 0.5-2.0% Mn, is hot-rolled and then cooled at >=2 deg.C/sec cooling rate from the temp. region of (Ar3 +40) to (Ar3 -80) deg.C, determined by steel components. The above Ar3 transformation temp. is determined by the following equation: Ar3 ( deg.C)=910-310C(%)-80Mn(%)-20Cu(%)-15Cr(%)-55Ni(%)-80Mo(%). By using the resultant steel stock, the steel member for beams and pillars of a steel-frame building, iron bridges, etc., can be obtained. This steel member has a metallic structure composed of ferrite, bainite, etc., and having 10-80% ferrite area ratio. Moreover, the minimum gradient of the nominal stress-nominal strain curve is positive, and this steel member is increased in buckling strain and has excellent buckling resistance.
