Title: Butt welding method of coil materials
Inventor: OBOKATA SADAO
IPC: B23K37/04
Filed: 1982-06-25
Abstract: PURPOSE:To assure high butting accuracy and to obtain a good result of welding without any strain in the butt end parts, by controlling stepwise the moving speed for butting coil materials. CONSTITUTION:The end part of a preceding coil S1 moving in an arrow direction and the top part of a succeeding coil material S2 are clamped respectively by means of the upper and lower clamps 2a, 2b and 3a, 3b of clamping devices 2, 3 on a stationary side and a movable side. A cutting device 1 is advanced into between both devices 2 and 3 by a driving device 7 and is stopped on the line, then the lower blade 6 of the device 1 is moved upward to a home position by a cylinder 6a, whereafter an upper blade 5 is moved downward by a cylinder 5a to cut the end parts of the materials S1, S2. The device 3 is advanced at a high speed by a cylinder 11, and is stopped apart at a spacing (e) just prior to butting. A backing strip 12 is pressed in the butt end parts of the materials S1, S2 and the cut end parts are sandwiched from the bottom side of the clamps 2a, 2b. The device 3 is advanced this time at a low speed to butt the end parts of the materials S1, S2; thereafter, the butt parts are welded along the butt line by a welding torch 21.

Title: Method for controlling absorption liquid concentration in sodium thiosulfate denitration method
Inventor: KOBUCHI AKIRA
IPC: B01D53/56
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To reduce the expense for chemicals by using only a suitable amount of the chemicals while making the thiosulfate concentrations of both absorption parts appropriately controllable, by installing a redox potentiometer to an absorption part at a first step, and controlling the amount of a thiosulfate solution to be fed to an absorption part at a second step based on a measured potential value. SOLUTION: A first denitration tower 1 introduces an exhaust gas from an introduction pipe 20, circulates it in an upward flow to a filling layer 11, while feeding an absorption liquid for ma circulation pipe 23, circulates it in a downward flow to the filling layer 11, and removes by absorbing nitrogen oxides. Further the absorption liquid, after being staied in a liquid staying part 13, is circulated to an upper part of the filling layer 11 by a circulating pump 6 of the circulation pipe 23. Further, a portion of the absorption liquid is fed from a branched pipe 25 to a second denitration tower 2. In this case the redox potential of the absorption liquid in the first denitration tower 1 is measured by a redox potentiometer 10, and a thiosulfate concentration is measured by a controller 5.  Then, a flow rate of the thiosulfate solution fed to the second denitration tower 2 is suitably controlled based on the measured potential value.

Title: Fuel feed controlling method at acceleration of internal-combustion engine
Inventor: YAMATO AKIHIRO
IPC: F02D41/00
Filed: 1984-05-30
Abstract: PURPOSE:To prevent a driving shock in time of acceleration from occurring before it happens, by synchronizing an accelerating fuel quantity with each control signal to be produced in consecutive order at the specified driving range and thereby increasing the quantity gradually till it reaches the specified value. CONSTITUTION:Whether an engine speed is in the specified range or not is judged with steps 2 and 3, while whether throttle opening thetan is less than the specified opening thetaSOFT1 or no is judged. If it is discriminated as being driven by acceleration from a low load range, a flag is set with a step 11. At the time of a relief condition being effected, a throttle valve opening variation DELTAtheta is judged with a step 17. A specified factor value KSOFT set by a step 18 is used for operation of fuel injection time TOUT, whereby fuel increment immediately after transfer to an accelerating state is checked. Thus, a driving shock due to a sudden increase in engine output torque attributable to the oversupply of an accelerating fuel quantity is prevented from occurring before it happens.

Title: Stereo signal demodulating circuit
Inventor: HIGASHIYAMA NAOTOSHI
IPC: H04H40/63
Filed: 1979-08-31
Abstract: PURPOSE: To prevent degradation of the separation degree dependent upon lowering of the power source voltage and achieve a low distortion rate, by using a composite signal as the crosstalk components cancelling signal of the switching demodulation output.  
     CONSTITUTION: Composite signal 18 is amplified by emitter-grounded amplifiers 16 and 17 and is applied to emitters of transistors 11 and 12. Transistors 11 and 12 become conductive alternately by switching signals 24 and 25 and separate the composite signal into left and right channel signals to supply them to output circuits 40 and 50. Meanwhile, crosstalk components are cancelled by applying the composite signal, which has the level adjusted, from crosstalk cancelling circuit 35 to output terminals 2 and 3. As a result, the separation degree is not degradated even if the power source voltage is lowered to saturate transistors 9 and 10, and base potentials of transistors 16, 11 and 12 can be made low to achieve a low distortion rate.

IPC: G01K7/25
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To detect temperature with precision and accuracy by detecting and correcting both a shift constant and a gain constant (temperature coefficient). SOLUTION: An output change following temperature rise after electric power application to a temperature detecting part 1 on a semiconductor substrate 7, acting as a reference, and a gain constant are measured in advance, and further an output change following temperature rise after electric power application to the temperature detecting part 1 on optional semiconductor substrate 7 is measured in advance. By this way, based on G=G0 (ΔV/ΔV0 ), where G0 is gain constant acting as reference and Δ/Δ0 is output difference, a gain constant G of the temperature detecting part 1 of the optional semiconductor substrate 7 is deduced. Thus, even the gain constant which cannot be corrected in conventional manner is corrected.  In addition, the gain constant acting as a reference is, sufficiently leaving the temperature detecting part 1 in different temperature atmospheres, also measured with erase based on output difference,  V( TT1) -V( TT2) }/ T1[ deg.C]-T2[ deg.C]} immediately after electric power application or when the temperature is equilibrated.

Title: Light detector
Inventor: MAKIUCHI MASAO
IPC: G02B6/30
Filed: 1987-05-09
Abstract: PURPOSE:To make the integration easy by a method wherein a waveguide is formed collectively at a light detector and the light is made easily incident so that the efficiency to couple with an optical fiber can be enhanced and that the light can be made incident from a cleavage face. CONSTITUTION:This detector is constituted in such a way that semiinsulating compound semiconductor waveguide layers, e.g., semiinsulating AlGaAs light waveguide layers 12A, and compound semiconductor light-absorption layers whose conductivity type is an i-type or a type close to the i-type, e.g. n-type GaAs light-absorption layers 12B, are laminated alternately. If the light L is incident in a state that a reverse bias voltage from a power supply E is impressed between a region 14 and a region 15, an electron and hole pair is generated in the light-absorption layers 12B. In the light waveguide layers 12A, the light which is incident from an oblique direction advances while it is reflected between the light- absorption layers 12B whose refractive index is small as compared with that of the light waveguide layers 12A; it generates the electron and hole pair when it enters the light- absorption layers 12B. The light is hardly detected at a tapered part 16A from the electron and hole pair generated in this manner. Because a distance from the p-type impurity diffusion region 14 to the n-type impurity diffusion region 15 is short at a straight part 16B, an electric field is sufficiently high and the electron and hole pair is separated; the light is then detected.
