Title: Abnormality detection method for sampling system and gas analyzer having abnormality detecting function
Inventor: INOUE TETSUSHI
IPC: G01N1/22
Filed: 1995-09-30
Abstract: PROBLEM TO BE SOLVED: To detect abnormality of a sampling system easily, reliably and inexpensively by comparing the time to be elapsed before the pointer of a gas analyzer begins to swing after starting calibration gas supply or the rising (or falling) time of concentration output due to the calibration gas with a reference value. SOLUTION: When calibration is performed by introducing a span gas to a sampling system 1 after finishing calibration with zero gas, an abnormality detecting/processing section 91 measures the time (dead time) required before the pointer of a gas analyzer 7 begins to swing after starting the span gas supply or the time (rising time) required for 90% response of concentration output due to a calibration gas. If the measurement deviates a preset normal reference value (range), such a judgement is made that the sampling system 1 is abnormal and an alarm 11 is actuated. Since the objective section for abnormality detection can be modified appropriately by switching solenoid valves 21-25, more accurate trouble shooting can be realized.

Title: Semiconductor laser device
Inventor: KASAI JUNICHI
IPC: H01S5/00
Filed: 1986-11-21
Abstract: PURPOSE:To scale up spot size, to reduce recombination in a quantum well in a clad layer and to increase an output by conforming the uppermost end of the quantum level of electrons in the quantum well to the energy level of a barrier layer in the width of the quantum well of the clad layer. CONSTITUTION:When the uppermost end of a quantum level coincides with the energy level of a barrier layer, probability in which electrons once injected escape to the outside of the quantum well is increased, thus making the quantity of electrons injected smaller than other cases. On the other hand, the refractive index of quantum well structure takes the intermediate value of the refractive indices of a well layer and the barrier layer. Consequently, when quantum well structure is used as a clad layer, the difference of refractive indices can be minimized without changing the difference of the forbidden band width of an active layer and the clad layer. Accordingly, the spot size of light emission can be scaled up without altering the confinement of carriers to the active layer.

Title: Manufacture of medium-or low-carbon ferromanganese
Inventor: YAMAMOTO KOTARO
IPC: C21C5/28
Filed: 1986-11-20
Abstract: PURPOSE:To reduce raw material costs to the minimum in inhibiting Mn oxidation in the course of blowing at the time of subjecting molten high-C ferromanganese to top blowing of O2 gas and bottom blowing of O2 and inert gases so as to improve the yield of Mn. CONSTITUTION:The top blowing of O2 gas and the bottom blowing of O2 and inert gases are applied to the molten high-C ferromanganese to carry out decarburization until the prescribed C quantity is reached. In the course of this decarburizing stage, particularly from its relatively early stage, Mn ore along is positively charged into a reaction vessel so as to increase the activity of MnO in slag and inhibit the oxidation of Mn. Further, by charging the Mn ore, effects of lowering the temp. of the molten metal and inhibiting the evaporation of Mn are produced, but, with all the above means, the oxidational loss of Mn cannot be reduced to zero. Accordingly, after the completion of the decarburizing stage, a reducing agent is added while agitating the molten metal by means of the bottom blowing of inert gas, so that MnO formed by the oxidation of Mn and also MnO resulting from the added Mn ore are reduced to undergo recovery of Mn.

Title: Error compensation type current transformer
Inventor: KITAGAWA HIDEO
IPC: H01F27/42
Filed: 1988-11-01
Abstract: PURPOSE:To eliminate the effect of secondary impedance and prevent the measurement accuracy from decreasing by change of the leakage impedance of a secondary winding, even if caused by change of the temperature, by grounding the connection point of a compensating impedance circuit, connected between the non-inversion input terminal of an operational amplifier and the secondary winding of a current transformer, and the secondary winding of the current transformer through a load and obtaining a quantity to be measured from a secondary current flowing back to the other end of the secondary winding through the load. CONSTITUTION:A load 3 is connected between the connection point of the secondary winding 1b of a current transformer 1 and a compensating impedance circuit 13 and a grounding point. The output voltage v1 of an operational amplifier 10 is divided by voltage dividers Zn and Zm and the obtained voltage V'' is applied to the non- inversion input terminal of the operational amplifier 10. The secondary induction voltage E'' of the current transformer 1 equals {Z21-(Zn/Zm).Zf}.I2. To make E'' equal to zero, Zn/ Zm must equal Z21/Zf. Therefore, setting impedance Zm, Zn, and Zf so as to meet this requirement enables eliminating the secondary induction voltage E'' to eliminate an exciting current I0; therefore, an error can be compensated.

Abstract: PROBLEM TO BE SOLVED: To provide a device for forming external electrode of electronic parts which can reduce the cost load associated with the replacement of a belt which holds and carries chip parts by prolonging the service life of the belt. SOLUTION: When tapered sections C are provided at the front end sections of pins 3b, 6a, and 9a and the minimum diameters Dmin of the tapered sections C appearing at the front end faces of the pins 3b, 6a, and 9a are made smaller than the diameter R of parts holding holes 2b, the occurrence of such a case that the front end faces of the pins 3b, 6a, and 9a come into contact with the opened ends of the parts holding holes 2b of elastic bodies 2 can be avoided. Especially, when the difference between the maximum diameter Dmax and minimum diameter Dmin of the tapered sections C is adjusted to a value larger than the error of the arranging intervals S of the elastic bodies 2, the collision of the front end faces of the pins with the opened ends of the parts holding holes 2b can be avoided more surely.  In addition, the damages to the parts holding holes 2b themselves when the pins 3b, 6a, and 9a are inserted into the holes 2b can be reduced, because the holes 2b can be expanded with no resistance by utilizing the inclined external surfaces of the tapered sections C even after the pins are inserted into the holes 2b.

IPC: H01L23/29
Filed: 1988-11-01
Abstract: PURPOSE:To eliminate tie-bar cutting process and solder bridge and to improve moisture resistance by composing the tie-bar for a lead frame of resin different from the mold sealing resin and containing the tie-bar in the package when the mold is sealed thereby eliminating the necessity of cutting tie-bar. CONSTITUTION:A tie-bar 1 is made by contacting resin having high melting point, e.g., a highly heat-resistant polyimide adhesion film, tightly with each lead and adhered to a lead frame having no lead frame such that it covers the lead vertically and horizontally. The highly heat-resistant polyimide adhesion film is adhered to the border of resin seal. Then bonding, molding (epoxy resin) and lead formation are carried out thus constituting a package. Since the highly heat-resistant adhesion film contacts with a lead at the border of resin seal, adhesion does not degrade and good moisture resistance is achieved. Furthermore, since the tie-bar is contained in a mold package, solder bridge can be prevented.
