Title: Semiconductor integrated circuit
Inventor: YAO TAKEYUKI
IPC: H01L27/092
Filed: 1986-09-18
Abstract: PURPOSE:To normally operate a switching circuit and to make a current across an integrated circuit become below a holding current and to enable an automatic return from a latch-up state, by detecting a drop due to the latch-up in a power voltage and interrupting supply of the power voltage to the integrated circuit for a prescribed time and forming a power voltage drop detection circuit and the switching circuit on an insulating layer of the same substrate as the integrated circuit. CONSTITUTION:Transistors 3 and 4, resistors 5 and 6, a capacitor 7, and a diode 8 in addition to a CMOS circuit 2 are formed on a silicon oxidizing film formed on a silicon substrate. When some noise causes the CMOS circuit 2 to be latched up and a large current flows across the CMOS circuit 2, a potential on a power source line 9 is lowered and the transistor 3 is turned on, so that the power voltage VCC is applied to the capacitor 7. Subsequently a potential on a gate terminal of the transistor 4 is temporarily raised to turn off the transistor 4. Thus the power source line 9 of the CMOS circuit 2 is interrupted from the power voltage VDD so that the latch-up can be avoided.

Title: Manufacture of semiconductor laser
Inventor: TAMURA HIDEO
IPC: H01S5/00
Filed: 1984-10-22
Abstract: PURPOSE:To obtain the manufacturing method of an efficient semiconductor laser whose mass productivity is high, by removing highly reflecting films, which are formed on the upper surface of a mask for vertical side walls by lift-off, dividing a semiconductor wafer along grooves, and obtaining laser chips. CONSTITUTION:A groove 54, which has vertical side walls 56 deeper than an oxide active layer 32, is formed in a semiconductor wafer 52 by dry etching. With the vertical side walls 56 vertically positioned with respect to a sputtering target 20, sputtering is performed. Thus, highly reflecting films 58 and 60 are simultaneously formed on the vertical side walls 56, which are to become the end surfaces of the resonators on both sides of the groove 54. Then the highly reflecting films 58 and 60, which are attached to the surface of a semiconductor wafer other than the side walls of the groove, are lifted off by a mask 46, which is used in forming the groove. The semiconductor wafer 52 is divided by a scribing method along the groove 54, and individual semiconductor laser chips are obtained. By forming the highly reflecting films 58 and 60 on the vertical side walls 56, part or all of the light emitted from the active layer 32 is reflected and an internal Q value in the semiconductor laser is enhanced. Thus, the threshold current is decreased, and highly efficient, stable operation is realized.

Abstract: PURPOSE:To contrive to reduce the processes by enabling the information writing of an ROM at the final step in the manufacturing process by a method wherein the threshold voltage of a MISFET is controlled by X-ray irradiation at the final step in the manufacturing process for the IC equipped with the ROM. CONSTITUTION:By excluding the memory array MA forming region of an n<-> type semiconductor substrate 4, a p type well region 5 is formed in its required main surface part to construct the n-channel MISFET. After insulation films 6 and 7 are formed, impurities for adjusting the threshold voltage of the p-channel MISFET are introduced to the MA part and to the neighborhood of the substrate surface in a required peripheral circuit part other than said part. At this time, the threshold voltage is set at about 0.5V so as to obtain a threshold voltage whereby the MISFET serving as the memory element turns on. Next, gate electrodes 8-10 are formed, and an insulation film 11 that covers them is formed. Then, a mask 19 to resist X ray irradiation is formed. This device is irradiated with X rays by using this mask, and thus the threshold voltage of the MISFETQ12 is controlled so as to be more than a desired voltage, e.g., an operating voltage of 5V.

Title: Snubber circuit for three-phase cycloconverter
Inventor: FUJIMOTO HISASHI
IPC: H02M7/48
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To improve the conversion efficiency of a three-phase cycloconverter by adding very few circuit parts to a snubber circuit for the cycloconverter and regenerating the energy of a snubber capacitor to electric power during the period based on the resonance frequency with the inductance of a high-frequency single-phase AC power source side. SOLUTION: A snubber circuit 20 is provided with a snubber capacitor 21, a first diode 22, a second diode 23, and an auxiliary switching element 24. When the element 24 composed of a transistor, etc., is turned on, the energy absorbed by the capacitor 21 is regenerated to a high-frequency single-phase AC power source side and the voltage of the capacitor 21 drops to the rectified value of the secondary-side voltage of a high-frequency transformer 12. When the element 24 is turned off, the energy in the snubber circuit 20 is discharged through the second diode 23 so as to suppress the jumping voltage which is generated when the element 24 is turned off. Therefore, the conversion efficiency of a three-phase cycloconverter can be improved.

Title: Solar cell and solar cell module
Inventor: FUJIOKA YASUSHI
IPC: H01L29/861
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To restrain the short circuit of a solar cell module from being generated when light is shut off partly at high humidity by a method wherein a bypass diode is used as an i-n or i-p junction diode element which is deposited and formed on a conductive substrate and which is composed of a silicon non-single- crystal semiconductor. SOLUTION: Since a semiconductor layer at a solar cell element 101 and a semiconductor layer at a diode element 102 are composed of a silicon non- single crystal of the same quality, the semiconductor layers are formed simultaneously on a conductive substrate. Since a direction toward a collector electrode 108D from the conductive substrate 103 in the diode element 102 is a forward direction (or a reverse direction), the diode element 102 is parallel-connected to the solar cell element 101 in the reverse direction when the collector electrode 108 at the solar cell element 101 and the collector electrode 108D at the diode element are connected by a conductor 109, and the diode element acts as a bypass diode. Thereby, even when light is shut off partly in the array of tandem solar cell elements, a reverse voltage which is applied to a light-shielding element becomes low, and the short circuit of the element can be suppressed.

Title: Terminal equipment
Inventor: MOTOHAMA HIDESHI
IPC: H04M1/253
Filed: 1989-08-28
Abstract: PURPOSE:To prevent useless transmission by starting the transmission based on the detected operating state of a B-channel. CONSTITUTION:An operation panel 7 is operated to receive a call setting command. A main control section 8 sends a call setting message SET to a bus 13 through a B-channel via a transmission section 1. The message SET is sent to an ISDN line 12 via a DSU 11. A line use detection section 6 detects a call setting reception message and a reply message from the D-channel on the bus 13, informs them to the main control section 8 to start the transmission control of picture information. Since either of the two B-channels of the line 12 is designated by a reception message, the control section 8 discriminates it that the designated B-channel is usable and which of scanner transmission and memory transmission is to be designated is discriminated by a panel 7. In the case of the scanner transmission to be designated, a scanner section is started to command the transmission of the picture information to the transmission section 1 and the transmission section 1 sends the picture information to the usable B-channel. Thus, useless transmission is not repeated and sure transmission is attained.
