摘要： PROBLEM TO BE SOLVED: To reduce an unbalanced load applied to a car frame guide device by arranging guide rails on the front side landing side more than the center of gravity of a car, and arranging a pulley arranged under a forcing-up type car frame on the rear car gravity center side opposite to the landing side to the guide rails. SOLUTION: Guide rails 2 for guiding lifting of an elevator are arranged on the front side passanger landing side of the center of gravity of a car. A suspension pulley 15 under a car frame 30 is arranged on the anti-landing side to the guide rails 2 in parallel to a surface of both side guide rails 2 for guiding lifting of a car 10. The suspension pulley 15 is arranged close to the guide rails 2 to the center of gravity of the car 10. A position of this suspension pulley 15 exists on the guide rail 2 side more than the center of gravity of the car to reduce an unbalanced load applied to guide devices 5a, 5b arranged in upper/lower parts of the car frame 30 to thereby facilitate clearance adjusting work of the guide devices 5a, 5b and an emergency stopper 16.

摘要： PROBLEM TO BE SOLVED: To facilitate the door opening work when a door-lock accident is generated by integrally forming a door lock push-up part, a first extension part, a door rail recess folding part, a second extension part, a handle recess folding part and a third extension part with each other while using a wire material having a thickness capable of being inserted into a clearance between a door and a jamb. SOLUTION: At the time of door opening work when door-lock accident of an elevator car is generated, a handle 8 of a door outer opening tool 1 is held, and a door lock push-up part 2 is made to come close to a clearance between a door and a jamb. Continuously, the door lock push-up part 2, a first extension part 3, a door rail recess folding part 4 are inserted into the clearance between the door and the jamb, and thereafter, the handle 8 is turned at 90 degree so as to avoid the interference of the handle 9 with a door rail 11. In this condition, the door outer opening tool 1 is pushed upward so as to rotate a lock fitting 12A of the door lock 12, and the lock condition is thereby released. The door is towed for opening, and the door-lock condition is canceled.

摘要： PROBLEM TO BE SOLVED: To achieve stable ionization even during measurement for a long period so as to enhance accuracy and reproducibility of data by preventing a needle electrode, a fine pore electrode and a fine from being smeared or clogged in a liquid chromatograph mass, spectrometer for an atmospheric pressure ionizing method. SOLUTION: A sample component flowing from a liquid chromatograph LC3 is heated to be atomized together with a mobile phase solvent by a nebulizer 6. The atomized sample and the mobile phase solvent are further heated in a solvent removing chamber 7. Most of the mobile phase solvent is evaporated, to be discharged outside of the nebulizer. The sample reaches an ionizing chamber 20 together with the remaining solvent. A needle electrode 8, to which a high voltage is applied, is housed inside the ionizing chamber 20. A corona is discharged from the tip of the electrode 8, thereby ionizing the mobile phase solvent. Subsequently, a proton shift reaction is generated between ions of the solvent and molecules of the sample, resulting in ionization of the sample molecules.

摘要： PURPOSE:To carry out a qualitative analysis and a quantitative analysis in a short time by pouring at a time, by carrying out the qualitative analysis by making the ion acceleration speed constant in sweeping a magnetic field current, while carrying out the quantitative analysis by varying the ion acceleration speed in a specific constant current value in the above sweeping. CONSTITUTION:In sweeping a magnetic field current in a qualitative analysis, a computer 13 maintains the current value constant for a specific time from the condition a little lower than the maximum value which is the final current value by a magnetic field current sweeping power source 11, repeating the operation to maintain the current value for a specific time from the condition further a little lower than the former value, and it is lowered up to the minimum value of the magnetic field current. As a result, the sweeping wave-form of the magnetic field current from the qualitative analysis to the quantitative analysis after that qualitative analysis forms an ascending slope consisting of a specific incline during the qualitative analysis, and a decending slope of the form of stairs in the quantitative analysis thereafter. In such a way, a specific magnetic field 6 is in the fixed condition for a specific time, and by varying the ion acceleration voltage in this case, the intensity responding to every mass number can be obtained, and the quantitative analysis can be carried out.

摘要： PURPOSE:To improve the decelerating performance of a capstan motor by outputting an inversion signal during a period from the switching time of a magnetic tape traveling speed from a high mode to a low mode up to the generating time of a coincidence signal. CONSTITUTION:When the rapid mode is switched to the slow mode (time t0), a reference value setting circuit 5 sets up a reference value nu2 and a speed control circuit 8 sets up an f-V characteristic corresponding to the reference value nu2. A mode switching signal MS is decayed, and at that time t0, an inversion control circuit 7 starts to output an inversion signal IN. Reverse torque is applied to a capstan motor 1 and its rotational speed is gradually reduced from a regulated rotational speed nu1. The rotational speed nu to be a measured result outputted from a measuring circuit 4 is compared with a reference value nu2 set up in a reference value setting circuit 5 by a comparator 6, and when the speed nu coincides with the reference value nu2 (time t1), the comparator 6 outputs a coincidence pulse EP. Consequently, the circuit 7 stops the output of the inversion signal IN.

摘要： PROBLEM TO BE SOLVED: To be capable of stably performing tension control even if a control input signal used for the tension control of a material to be rolled is switched and stably performing the tension control of the material to be rolled.SOLUTION: A pressure command correction amount learning unit 3 learns a coefficient of a relevant equation representing correlation between a pressure detection value obtained by a pressure detection unit 27 and a first pressure command value correction amount based on a load detection value calculated by a first pressure command correction unit 24 when there is no abnormality in a load detection value obtained by a load detection unit 28. A device of controlling tension of a material to be rolled 1 switches a pressure command value correction amount used by a pressure command calculation unit 20 from the first pressure command value correction amount calculated by the first pressure command correction unit 24 to a second pressure command value correction amount calculated by a second pressure command correction unit 25 based on correlation studied by the pressure command correction amount learning unit 3 when a normal load detection value cannot be obtained by the load detection unit 28. Since these correction amounts are correlated, the correction amount is not largely changed during switching. Accordingly, the tension control of the material to be rolled does not become unstable.
