Abstract: PROBLEM TO BE SOLVED: To obtain a high-performance device having a low threshold current density and simple structure by using for the active layer a semiconductor mixed crystal composed of a nitride and a compd. of an element having a higher spin orbit splitting energy than that of N. SOLUTION: The active layer uses a semiconductor mixed crystal composed of a nitride and a compd. of an element having a higher spin orbit splitting energy than that of N and this element is pref. As, P, or Sb. The spin orbit splitting energy Δ2 near the valence band top end of a GaN1-x Asx mixed crystal rapidly rises when the As content becomes large. The relation between the injection carrier density in an Al0.2 Ga0.8 N/GaN quantum well structure and optical gain is an shown in the chart at with Δ2=5meV (dashed line) and Δ2=25meV (solid line). Thus the injection carrier density required for laser oscillation is reduced by using such a semiconductor mixed crystal as described above.

Title: Testing method of mos integrated circuit
Inventor: TERASAKA KATSUMI
IPC: G01R31/30
Filed: 1980-06-10
Abstract: PURPOSE:To detect the fault in the MOS type integrated circuit being under the life test, by comparing the consumed current measured by a voltage which varies stepwise during the test and the consumption current before the test. CONSTITUTION:The MOS type integrated circuit 1 to be tested is connected to a current device 3 which generates a step shaped voltage via a current measuring device 2 for measuring the consumption current. Every time a clock signal comes from a clock signal generator 4, the consumption current of the integrated circuit 1 is measured at each step of the step shaped voltage. By the operation of a switch 7 the measured value before the test is stored in a first memory 8, and the measured value during the test is stored in a second memory 9. Then, the contents of the memories 8 and 9 are read out and applied on a comparator 14. Thus the values of the consumption current at the same step of the step shaped voltage are compared, and the output is generated by the comparator 14 when the measured value is changed. In this way the integrated circuit can be tested by a simple method.

Title: Surface acoustic wave element
Inventor: KOBAYASHI ATSUSHI
IPC: H03H3/08
Filed: 1978-06-28
Abstract: PURPOSE:To reduce undesirable coupling between the input and output terminals, by locating the pair of draw-out line terminals adjacent to each other from the surface acoustic wave element orthogonally. CONSTITUTION:At the input terminal draw-out line section from the surface acoustic wave element chip 15, the conductor plates 12, 13 being the input terminals are opposed each other by clipping the insulator substrate 11. Further, the conductor plates 17, 18 being the output terminals are bonded at the same side of the insulating plate 11. Accordingly, the plane including the input terminal pair and the plane including output terminal pair are orthogonal each other. As a result, since the magnetic flux phi1 produced from the input side loop and the magnetic flux phi2 generated from the output side loop are orthogonal, to remarkably reduce the mutual inductance, undesired coupling can be reduced.

Title: Overcurrent limiting circuit
Inventor: MASUKO AKINOBU
IPC: G05F1/573
Filed: 1981-05-25
Abstract: PURPOSE:To control the overcurrent, by feeding the detection output of the overcurrent back to the element that converts the input signal into the voltage when the overcurrent flows to the output of an IC-changed power source which is supplied by the input signal of positive polarity. CONSTITUTION:A constant current source consists of a reference voltage source E, a transistor (TR) Q2 and a resistance R1. When the input voltage of positive polarity is supplied to the base of the TRQ1, the TRQ1 conducts to convert the signal into the voltage by the TRQ2. Then TRs Q3 and Q4 conduct by the converted voltage. In such way, the electric power is supplied to a load L. Furthermore, the TRQ5 connected in parallel to the TRQ4 also conducts, and the voltage drop emerging across the resisance R3 is supplied to the TRQ6. When the allowance current I2 flows to the TRQ5 due to the short circuit of the load L or the like factor to makes the TRQ6 conduct, the current flowing to the resistance R1 increases and the current flowing to the TRQ2 reduces. Accordingly, the current flowing to the load L can be limited to the prescribed value.

Title: Charging of storage battery
Inventor: KOIKE KIICHI
IPC: H02J7/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To improve life characteristic in an enclosed lead battery by determining the state of a storage battery based on the battery voltage after precharging to select a charging control method thereafter and then charging the battery based on the method. SOLUTION: After a certain period of time after finishing precharing, a storage battery voltage Vba1 in an open circuit is measured. If a first set voltage V1 > Vba1 > a second set voltage V2, it is determined that the battery is just slightly discharged and then constant-voltage charging is performed at the control voltage Vch1. When a charging current value drops to a specified value Ia, the control voltage Vch1 is reduced to a control voltage Vch2 lower than Vch1 (up to here, a first charging). If the second set voltage V2 > Vba1 > a third set voltage V3, it is decided that discharging progresses deeply and constant-voltage charging is performed at a third control voltage Vch3. When the charging current value is reduced to a specified value Ib, constant-current charging is performed at a current value Ic for a specified period of time (up to here, a second charging).  If a third set voltage V3>Vba1, the battery is decided to be in an overcharged state and active charging is performed at a fourth set voltage V4 which is lower than the third set voltage V3.
