Title: Method and device for monitoring weld strength in spot welding
Inventor: NAGASAWA YOSHIAKI
IPC: B23K11/25
Filed: 1981-01-29
Abstract: PURPOSE:To detect weld strength with extremely good accuracy by comparing the integratd value of the voltage drop after the max. value of the effective voltage removed of non-effective components from welding voltage with a reference set value. CONSTITUTION:Out of the voltage V between welding gun electrodes 2 and 3 derected  with a detection circuit 8, a component VN is removed with a removing circuit 9 for  the induction noise component VN. Following to this, the voltage Vr corresponding to  the loss components produced with the electrodes 2, 3 is removed with a removing circuit 10 for the welding gun electrode resistance component Vr, thereby leaving an effective component VR. This is removed of the component VN as the detection current of a  coil 15 is processed with a detection circuit 16 and the voltage is detected when dI/ dT=0. This signal goes through circuits 17, 19 and is subtracted by the addition of a  circuit 14. The circuit 24 of a processing circuit 11 stores the max. value out of the  resultant component VR, and a circuit 25 outputs the difference between this and the value lowered below this, and the decision of goodness is displayed via circuits 26,  28. Here, the integrated value by the circuit 26 has a sufficient correlation with the  effective diameter of nugget, and the decision of weld strength is made possible.

Title: Exhaust emission control device of internal combustion engine
Inventor: HIROTA SHINYA
IPC: B01D53/94
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent a catalyst for purifying exhaust emission from a diesel engine from being poisoned with SOF. SOLUTION: A light oil as a reducer is added by a reducer adding device 30 into an exhaust pipe 21 for connecting a diesel engine to a selective reduction type NOx catalyst. The light oil contained in a light oil tank 31 is fed to a carburetor 33 by a feed pump 32, heated by a heater 37, and evaporated in a casing 36. The evaporated light oil is fed to a separator 34 in the state that its high boiling point components are mixed with its low boiling point components, cooled by a coolant 39, the high boiling point components are condensed and adsorbed by the coolant 39, and only the low boiling point components are added into the exhaust emission pipe 21 through a reducer feed pipe 35. The low boiling point components are, even if adhered to the catalyst, merely oxidized and changed into carbon dioxide under the temperature of the exhaust emission.  Thus the catalyst is not poisoned with SOF.

Abstract: PROBLEM TO BE SOLVED: To stabilize the film forming rate over a long period by a simple constitution free from the need of the accumulation of data by changing the contact area between the inside wall face of a chamber and plasma and controlling the reactance of the discharge impedance of plasma. SOLUTION: In a vacuum chamber 1 in which gaseous Ar or the like is introduced from a plasma gas feeding source 6, a cathode 2 provided with a magnet 11 is applied with high frequency voltage from a high frequency power source 14 to generate plasma 23. Ions in this plasma 23 are accelerated to sputter the surface of a target 8, by which the target material is deposited on a substrate 4 to form a film. In the above sputtering device, the reactance of the discharge impedance of the plasma 23 is measured by an impedance monitor 15, and a motor 18 is controlled via a computer 16. Thus, a movable board 21 in a subchamber 17 is moved to change the contact area between the plasma 23 and the inside wall face of the chamber, and the above reactance is controlled to the set value.

Title: Negative resistance semiconductor element
Inventor: KOIKE HIDEJI
IPC: H01L21/331
Filed: 1979-02-07
Abstract: PURPOSE: To obtain a negative resistance element of a small area by integrating a JFET and a MOS diode unitarily.  
     CONSTITUTION: The n -  layer 2 is formed in the p - -type semiconductor substrate 1 and the p - -layer 3 is made in the layer 2 as a gate layer to form an n-channel JFET. The n + -layers 4, 5 by which the layer 3 is sandwiched are provided in both ends of the layer 2. The p + -layer 6 that is made contact with the layer 4 is formed in the surface of layer 3 and the gate electrode 8 is provided on the layer 6 through the insulating film 7 to form an enhancement type MOS diode. The junction of both the layers 6, 4 makes up a Zener diode that conducts by a reverse bias approximately equal to zero. The electrode 8 is connected to the layer 5, voltage VA is applied to it and the layer 6 is grounded together with the substrate 1. When the voltage reaches the threshold V 1  of FET, current is saturated and it is reduced after reaching the threshold V 2  of diode. When voltage more than the sum V 3  of the threshold value is applied, both the FET and diode are cut off, the current becomes about zero, and the negative resistance is shown. The area of this element is very small since it is the same as that of of piece one JFET.

Title: Method of controlling operation of synchronous motor
Inventor: OKUYAMA TOSHIAKI
IPC: H02P27/06
Filed: 1979-02-07
Abstract: PURPOSE: To prevent a thyristor from overheating at its current concentrating time by interposing a step-up transformer between a converter and a generator at its stationarily operating time, coupling the converter to the generator directly at its current concentrating time and reducing the output current of the converter.  
     CONSTITUTION: A converter 3 for converting a DC current obtained from a converter 1 to an AC current having predetermined frequency is connected through a step-up transformer 14 to a synchronous motor 4. When a current is concentrated due to deceleration of the speed, a change-over switch 15 of a transformer 14 is opened by a signal from an instructing circuit 17 connected to a speed detector 6, and a switch 16 is closed to apply the output of the converter 3 directly to the motor 4. On the other hand, the circuit 17 generates also a signal to a current limiter 18 to reduce the DC output current from the converter, for example, to 1/3 of that at the stationary time.

Title: X-ray resist
Inventor: TAKECHI SATOSHI
IPC: H01L21/027
Filed: 1989-01-20
Abstract: PURPOSE:To obtain the resist highly sensitive to X-rays by mixing the metal salt monomer of (meth)acrylic acid expressed by the specific formula with a radiation sensitive resist. CONSTITUTION:The metal salt monomer of the (meth)acrylic acid expressed by the formula I is mixed with the radiation sensitive resist. In the formula, R denotes H or CH3; n denotes 2 to 3; M denotes a metal ion. Since the metal absorbs X-rays, the metal salt monomer of the (meth)acrylic acid in which the metal is converted to the form of the soluble salt is used. Since the monomer is not usable as a resist as it is, the monomer is used by mixing the same with the radiation sensitive resist, such as photoresist or electron beam resist. The reason for using the (meth)acrylic acid lies in that the (meth)acrylic acid is easily soluble in solvents and is easily modifiable as this acid has easily polymerizable double bonds, such as vinyl group. The metal element is incorporated into the resist by adopting such structure and, therefore, the absorption of X-rays arises and the higher sensitivity is attained.
