Title: Method and apparatus for evaluating corrosion control effect of anticorrosion film
Inventor: MATSUDA KYOJI
IPC: G01N21/65
Filed: 1995-05-23
Abstract: PURPOSE: To enable non-destructive evaluation of corrosion inhibiting effect of material to be measured without being exposed to actual environment by preparing a relational expression of a natural lattice frequency and the degree of corrosion inhibiting effect of an anticorrosion film. CONSTITUTION: An expression is prepared between a natural lattice frequency indicating the closeness of an anticorrosion film and the degree of anticorrosion inhibiting effect thereof. In other words, a stress X works on a close anticorrosion film because of a difference in thermal expansion coefficient between the film and a ground attributed to a difference between the temperature during the formation thereof and that during the use thereof. The stress X causes a change in the lattice constant and a natural frequency ω is changed. A formula of X0 .K.lxp(-c.R)=-Δω/ω indicating the frequency ω and the degree of the corrosion inhibiting effect R is obtained from this relationship of a value Δω of variation and the stress X.  Here, the constants K and c are calculated beforehand by measuring the effect R and the natural frequency ω+Δω of two kinds of films subjected to oxidation treatment. Then, the frequency ωof a vibration mode of material to be measured is measured to determine the degree of the effect R of the anticorrosion film to be measured by the expression already prepared on the basis of the measured value obtained.

Title: Construction method for cable frame
Inventor: FUKAO KOZO
IPC: E04H15/34
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To disperse fluctuation load as vibration energy by supporting end parts of a hoisting cable and a pressing cable by a fixation device of passive damper type having a tensile force variable function and a deformation absorption function. SOLUTION: In a passive damper type fixation device 10, a cable socket is connected with a rod 14 of a piston 12 through a pin joint 15, and an end part of a hoisting cable 1 or a pressing cable 2 is connected with the cable socket. Next, fixed magnitude of tensile force to the left is given to each cable by total force F of fluid pressure which acts of the piston 12. Then, when tensile force of the cable 1 or 2 increases due to fluctuation load, the buffer effect is given due to compression resistance of the fluid in accordance with slight right-going displacement of the piston 12 and the action of a restriction 18b of a damping mechanism 18 to follow up a rapid rise of cable tensile force. Consequently, the cable tensile force is not rapidly reduced even at this time, and the fluctuation load can be dispersed as vibration energy.

Title: Signal selection circuit
Inventor: MIMURA KAZUHIRO
IPC: H03K17/62
Filed: 1980-09-05
Abstract: PURPOSE:To prevent the leakage of a signal, by canceling the signal which is given to a switching means of a channel circuit not selected, in a circuit which can perform switching and selection of an output signal with a switching means. CONSTITUTION:When a switch 1a of a channel A selected is at an on-terminal side, a switching transistor (TR)3a only is conductive and a signal of a signal source 7a is outputted to a common resistor 5 for output. On the other hand, in channel circuits B, C not selected, control TRs 12b, 12c are conductive. Thus, the signal from the signal sources 7b, 7c is by-passed between the collector and the emitter of the TRs 12b, 12c, and the input signal to the emitter of the switching TRs 3b, 3c can almost be canceled. Thus, the leakage of signals can be avoided.

Title: Manufacture of electrically conductive elastic cable conductor
Inventor: ASAI MASATO
IPC: H01B1/02
Filed: 1989-05-18
Abstract: PURPOSE:To obtain the title conductor of high tensile-strength enough to withstand such stresses as bending, torsion, tension, etc., by making a cast of an alloy which contains 0.25 to 10wt.% of Cr and also has the remainder of elements other than the Cr, namely, Cu and P having its content limited to less than 100ppm, and then applying both a wire drawing process and an annealing process to this cast alloy. CONSTITUTION:Cr grains extended respectively in the cast direction thereof keep the directivity thereof even in manufacturing processes applied to the cast alloy, and yet the grains are dispersedly arranged into the alloy to heighten the elasticity of the alloy by leaps and bounds. P content exceeding 100ppm of the alloy causes the formation of an intermetallic compound of Cr-P for facilitating a reduction in the number of the extending Cr grains and also for easily coarsening them to have a bad effect upon the elasticity. And the Cr grains extended in the cast direction thereof as a result of unidirectional solidification casting keep the directivity thereof to heighten the elasticity of the alloy by leaps and bounds. Thus, a conductor showing excellence in strength, in conductivity and in elasticity can be obtained inexpensively.

Title: Tv signal discrimination circuit
Inventor: FUKAZAWA SHUICHI
IPC: H04N5/06
Filed: 1992-05-18
Abstract: PURPOSE:To make a TV pattern stable by using the output signal of an integration circuit so as to discriminate a standard signal from a nonstandard signal thereby resetting a relevant horizontal counter. CONSTITUTION:A 1st horizontal counter 6 counts a clock signal in response to a subcarrier signal frequency of a TV signal. Furthermore, a 2nd horizontal counter 8 counts the clock signal in response to the subcarrier signal frequency of the TV signal and reset by an external horizontal synchronizing signal or a simulated horizontal synchronizing signal generated by itself. Then a phase comparator circuit 10 compares the phase of the external horizontal synchronizing signal with the horizontal synchronizing signal from the counter 8. When the phases are consecutively dissident, a detection circuit 11 detects dissidence and its signal is integrated by an integration circuit 12. When the output of the circuit 12 indicates dissidence, the signal is discriminated to be a non-standard signal and the TV signal is discriminated to be the standard signal or the non-standard signal. When the signal is the nonstandard signal, the counter 6 is reset externally. Thus, the stable TV pattern is obtained.

     CONSTITUTION: For the first row of the horizontally disposed piles 1a 1b... a wave eliminating material 2 is placed between the pile 1b and the pile 1c and between piles 1d and 1e, respectively. For the second row of the horizontally disposed piles 1a, 1b..., the material 2 is placed between piles 1a and 1b, between piles 1c, and 1d, and between the piles 1e and 1f. For the third row of the horizontal disposed piles 1a, 1b..., the material 2 is placed between the piles 1b, and 1c and between the piles 1d and 1e. These materials are placed in zigzag in the proceeding direction of waves. Waves sequentially hit the materials placed in zigzag to disappear, however, water penetrates through the space of piles 3 where the material 2 is not placed. As a result, obstruction does not occur for the exchange of water and spending can be expected in the same degree of a wave eliminating wall in which waves are completely intercepted.

Abstract: PURPOSE: To obtain high-density plasma of a uniform distribution by radially arranging plural magnetic field coils on the outside wall in the upper part of a reaction chamber and passing AC currents of antiphases to each other in these adjacent magnetic field coils, thereby generating magnetic fields. CONSTITUTION: The plural magnetic field coils 1 are radially arranged along the outside front surface of the upper outside wall 12 of the reaction chamber 2 of a plasma etching device and the ACs of the antiphases are passed to the adjacent magnetic field coils 1. The magnetic fields B generated between the adjacent magnetic field coils 1 are then reversed in directions from each other. The E×B drift of the plasma by the magnetic fields B within the reaction chamber 2 are such that the E×B drift from the center to the outer periphery arises under the part between the certain coils and the E×B drift arises from the outer periphery to the center under the part between the coils adjacent thereto.  These drifts are reversed when the coil currents deviate by a half period and, therefore, the plasma is repetitively drifted from the center to the outer periphery and from the outer periphery to the center under the part between the one coil. As a result, the high-density plasma having the uniform distribution is obtd.

Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To decrease both the capacity for a working memory and computational operation and also to simplify the constitution of a code synchronous acquisition circuit by integrating the output power value of a matched filter which is equivalent to a single cycle of a diffusion code series in each of periods, defined by dividing the cycle of the diffusion code series equally into a prescribed number of 2 or more and then deciding the code timing, based on the integration value of each divided period. SOLUTION: A matched filter 13 has a diffusion code as a tap coefficient for the synchronous acquisition, reverse diffuses the receiving base band signals outputted from an A/D converter 12 and outputs this conversion result by each sampling timing. A signal power integrator 14 integrates the power value of the correlation output received from the filter 13 by each fixed period. This integration period is decided by the timing signal of a timing generator 15. The output of the integrator 14 is held in a memory 16 in each timing. A peak deciding part 17 decides the timing of the correlation peak, based on the contents held in the memory 16 and then decides the code timing.

Abstract: PURPOSE:To reduce the fluctuation of room temperature by controlling the heater and the convection fan in relation to the difference between the measured temperature by a room temperature sensor and the set temperature and by means of a timer circuit which counts the elapsed time after stopping the convection fan. CONSTITUTION:When the room temperature T reaches the set temperature Ts as the heater 2 and the convection fan 3 are operated, the heater 2 is stopped at the time t0. The convection fan 3 continues its operation some time thereafter and is stopped when all the residual heat of the heater 2 is released. The controller 4 starts counting time from the moment when the heater 2 stops its operation, and causes the heater 2 to remain being stopped for a certain time period t1 regardless of the measured temperature by the room temperature sensor 5 and to resume its heating operation after a certain elapsed time of t2. Within the time period between t1 and t2, the heating is stopped if the measured temperature T by the room temperature sensor 5 is higher than the set temperature Ts, and, if low, the heating operation is resumed.

Filed: 1991-04-26
Abstract: PURPOSE:To reproduce adjacent recorded tracks by scanning a corresponding recorded track and a precedent recorded track with magnetic heads, delaying an output signal of the magnetic heads and subtracting this from an output signal to be subsequently outputted. CONSTITUTION:Under the holding state of the magnetic heads 2A and 2B having each individual large head width Tw to offset the side of the precedent recorded track TB against their corresponding recorded track TA, a tracking error signal SER1 is generated by scanning the corresponding recorded tracks TA in turn so as to drive a capstan motor 37. An output signal S1 of the magnetic heads 2A and 2B is converted into a digital signal D1, and a delay signal D2 is generated by a memory circuit 38. The delay signal D2 is subtracted from the successively outputted signal D1 by a subtraction circuit 32, and an output signal D3 recorded on the corresponding recorded track TA is extracted. Thus, an effect in the case of the recorded track formed at the same azimuth can be canceled.
