Patent JP-H06326580-A (JP)
Title: Driving circuit
Inventor: MIYAZAKI TAKAHIRO
IPC: H03K17/0412
Filed: 1993-05-12
Abstract: PURPOSE:To provide a driving circuit in which power consumption is less and which operates at high speed. CONSTITUTION:Transistors Q1, Q2, Q3, P1 and P2, resistance elements R1 and R2 and diodes D1 and D2 constitute a high level supply circuit l setting an output terminal level to be high. A constant current source Ibs, a current mirror circuit MR12, transistors Q11, Q13 and Q14, a resistance element R11 and a Schottky diode 11 constitute a low level supply circuit setting the output terminal level to be low. When the output terminal (TOUT) level is changed to be high or low, large current flows into the base of Q3 or Q13 and the output terminal level is rapidly changed. When the output terminal level becomes prescribed voltage, current flowing into the base of Q3 or Q13 is eliminated or it becomes considerably small. Thus, power consumption in a normal state where the output terminal level is stabilized is small.

IPC: G10L13/047
Filed: 1988-05-07
Abstract: PURPOSE:To prevent the malfunction by inhibiting the output of voice by the signal of a voltage detecting circuit to display a lack of voltage at the time of fall of the voltage. CONSTITUTION:A power supply circuit 1 which supplies power to all circuits of a block, a voltage detecting circuit 2 using a comparator or the like, a selecting circuit 3 which selects proper voice or display, a display circuit 4 consisting of liquid crystal or the like, and a voice data storage circuit 5 are provided.

Title: Semiconductor laser device
Inventor: WATANABE HITOSHI
IPC: H01S5/06
Filed: 1990-04-25
Abstract: PURPOSE:To compensate for distortion generated in analog modulation, by converting an input modulation signal to a frequency generating the distortion with a frequency multiplier, shifting the phase by 180 deg. with a phase shifter, attenuating the amplitude with an attenuator, and again combining it with the original signal. CONSTITUTION:Input modulation signal 1 is branched into an original signal and a signal for distortion compensation; the branched signal for distortion compensation is converted to a frequency generating the distortion with a frequency multiplier 2; the phase is shifted by 180 deg. with a phase shifter 3; the signal level is adjusted to be a desired value with a variable attenuator 4; the obtained signal is again combined with the original signal, and inputted, as a modulation signal, in a laser 6. Hence the generated optical higher harmonic signal is canceled by the signal whose phase is shifted by 180 deg., and only the input modulation signal component can be led out. Thereby analog transmission free from distortion is realized.

Title: Saturable bragg reflector structure and fabrication thereof
Inventor: CUNNINGHAM JOHN EDWARD
IPC: H01S3/02
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a saturable Bragg reflector in which low optical loss is achieved by including one or more semiconductor quantum well in an n/2- wavelength strain relax layer (n is an odd number larger than 0) formed on a standard 1/4 wavelength stack reflector. SOLUTION: The saturable Bragg reflector comprises a plurality of quantum wells 12a, 12b, grown in an InP strain relax layer 14 which is grown on a 1/4-wavelength stack dielectric mirror structure 16. The mirror structure 16 comprises several layers formed in a GaAs/AlAs semiconductor compound which is formed on a GaAs substrate 18. It is grown on the first part of the strain relax layer 14 and the uppermost layer of the 1/4-wavelength stack structure 16 having a concentration of dislocation. When a sufficient concentration takes place in the interface region, these dislocations function as nonradiation recoupling sources. After saturation, these recoupling sources remove carriers of quantum well, before the next reciprocation of an optical pulse arrives at a laser cavity. According to the arrangement, low optical loss can be achieved and a high response time is obtained.

Title: Reference voltage generation device
Inventor: MEGURO RIYOU
IPC: H03K19/003
Filed: 1978-09-13
Abstract: PURPOSE:To obtain reference voltage with few variations and no need of adjustment after manufacturing by detecting the energy gap between Si semiconductors or the voltage smaller than this gap. CONSTITUTION:P layers 5 are formed on an N-type Si substrate 1 and N layers 6 are formed in a P-island 2. P-type and N-type polycrystal Si 7, 8 and intrinsic polycrystal Si 9 are selectively formed on each gate oxdation film. Then, with an insulation coating electrodes are provided to form P-channel FETA, B, C and N-channel FETD, E, F. Differences in Fermi levels between electrodes 7, 8 and 9 are taken out as reference voltages. Since the Fermi levels are little dependent on temperature, the differences in threshold voltages are also little dependent on temperature. When counecting drains and gates of FETT1, T2 in common and then operating thus obtained device at constant current I0, the difference in threshold voltages can be taken out from the difference in drain voltages because FETT1, T2 are different in their threshold voltages and equal in mutual conductances. Difference in Fermi levels between N-type and P-type semiconductors are obtained with use of N<+> and P<+> gate MOS.

Abstract: PURPOSE: To obtain excellent heat insulation property and sound insulation property by fitting a heat insulating board formed by integrally clamping a low density foam urethane plate by two pressure molded paper plates between two columns erected at a designated space between them and fixing the same by metallic plates. CONSTITUTION: A heat insulating board 6 clamped integrally with a low density foam urethane plate between two pressure molded paper plates, at least the outer surface of which are subjected to waterproof processing, is fitted between two columns 1, 2 of a building. Two columns 1.2 and the heat insulating board 6 are fixed by metallic plates 7, and further as the longitudinal central part of the low density urethane plate is clamped and fixed by a rafter and a furring fatten, the strength can be further increased. Accordingly, even if the external force is applied to the thus constructed wall from the directions of arrows 10-13 by an earthquake or the like, the connection between a set of columns 1, 2 and the heat insulating board 6 is strong so as to obtain a satisfactory earthquake resistant structure without a diagonal brace.

Abstract: PURPOSE:To suppress the obstruction of the flow of pachinko (pinball game) balls resulted from magnetization by making a demagnetizing device face one pachinko ball passage of either a circulation guide device or a ball supplying device to demagnetize the magnetism charged on pachinko balls. CONSTITUTION:A demagnetizing device 17 is made to face one pachinko ball passage of either a circulation guide device 5 or a ball supplying device 16 to demagnetize the magnetism charged on pachinko balls. Otherwise, a polishing device for polishing pachinko balls is provided in the course of the circulation guide device 5, for example, near the inflow port of a waiting gutter 12, and the demagnetizing device 17 is provided in the preprocess or post-process of the polishing device. Since the mutual attraction of pachinko balls by the residual magnetism or the attraction of the inner wall of the constituting member of a circulating passage with the pachinko balls by the residual magnetism is prevented, the pachinko balls can be smoothly circulated in the circulating passage.
