Title: Instrument and method for measuring voltage between electrodes of resistance welding machine
Inventor: KAWAI SHINGO
IPC: G01R19/00
Filed: 1993-06-14
Abstract: PURPOSE:To satisfactorily weld works by measuring the voltage between both electrodes where an induced component is removed to know up to what stage welding is proceeded by the voltage and carrying out pressurization, etc., of the electrodes properly according to it. CONSTITUTION:A voltage detection circuit 14 which detects the voltage between the detection ends of lead wires joined to each electrode 44, a current differential value detection circuit 12 which detects a value obtained by differentiating timewise a current flowing between both electrodes and an amplifier circuit 16 which amplifies the current differential value are provided and a subtracted value which is the difference between the detected voltage between the ends and the amplified current differential value is calculated by a subtraction circuit 18. The subtracted value is differentiated timewise by a differentiation circuit 20. This subtracted differential value is inputted to a polarity detection circuit 22, the polarity (positive and negative) is detected and a value of an amplification rate alpha in the amplifier circuit 16 is adjusted so as to attain a value of M (mutual inductance between the lead wires 72a and 72b and an arm). This adjustment is carried out by a binary retrieving method.

Title: Focusing method for photo graphic lens
Inventor: IMAI TOSHIHIRO
IPC: G02B13/02
Filed: 1977-11-29
Abstract: PURPOSE: To carry out focusing with the photographic lens of a very short whole length without influencing the lens power by shifing the third lens group of the former group in the photographic lens of telephoto type, and further, by giving each requirement of the formula I.  
     CONSTITUTION: In the formula I-1, if f 12 /f becomes less than 4, the light pencil outside the optical axid incident onto the lens of the third group is so largely inclined that its aberration deteriorates when focusing. and in the formula I-2, if f 3 /f becomes more than 0.7, it is required that the amount of shifting of the third group lens be larger, hence it is undesirable in connection with space as well as aberration. Further, in the formula I-3, according as the object approaches nearer, the third group lens must be moved in the direction of approaching the object so that the space required therefor should be ensured. If d/f becomes less than 0.04, it is unable to ensure the space. Thus, the lens power can be maintained by giving each requirement of the formula I thereto.

IPC: G01B21/08
Filed: 1985-06-28
Abstract: PURPOSE:To attain surely thickness data of each product after shearing by providing a thickness gauge on a line above the set position of a shearer to measure a thickness signal before shearing. CONSTITUTION:A rolled body 21 rolled by a finishing rolling mill is flowed to a line 20. At this time, measuring positions S1, R1, etc. set to a thickness data controller 24 are preset to a thickness gauge 23. When the rolled body 21 is flowed, the thickness in each of measuring positions S1, R1, etc. of the rolled body 21 is measured by plural gamma-ray detectors arranged on a thickness gauge truck, and the measured signal is stored in the controller 24. The rolled body whose thickness is measured is sent to a shearer 22 and is sheared to obtain product materials 21a and 21b. Each thickness data stored in the controller 24 is tracked to discriminate the quality of product materials 21a and 21b by a discriminating part of the controller 24 in accordance with thickness data S1-S3 and thickness data R1-R3 respectively. Thus, thickness of each product is attained automatically surely.

Filed: 1990-05-31
Abstract: PURPOSE:To stably obtain the reset pulse having narrow pulse width and a high level without depending on a power supply voltage by providing a low reset integrated circuit, a load resistance connected between an output terminal of the low reset integrated circuit and a power source, and a differentiating circuit connected to the output terminal. CONSTITUTION:An output side of a low reset integrated circuit (IC) 1 is pulled up to a power source Vcc by a load resistance R9, and also, to its output side, a differentiating circuit consisting of a capacitor C4 and a resistance R10 is connected. Accordingly, when the power supply voltage Vcc rises and reaches a threshold voltage Vth of the low reset IC 1, its output becomes high impedance, and a voltage Va rises suddenly. Subsequently, the rise of its voltage Va is differentiated by the capacitor C4 and the resistance R10, therefore, an output voltage Vo becomes a reset pulse of positive polarity of a waveform of a high level, and also, narrow pulse width. In such a way, the reset pulse of narrow width and a high level can be obtained stably without depending on the power supply voltage.

When all the zones are determined, the total generated energy P of each zone is calculated, the zone including the requested total generated energy C is selected, and a common increased fuel cost lambda0 is determined. An optimum economical generated energy is designated for each unit 3n based on it. Thus, a convergence calculation is eliminated, and the optimum economical generated energy is effectively obtained with small processing amount.
