Title: System for detecting quality of transmission line
Inventor: NISHI KIYOTAKA
IPC: H04L1/20
Filed: 1987-11-27
Abstract: PURPOSE:To precisely discriminate the deterioration of quality in a transmission line and the abnormality of a multiplexing device by alloting a time slot to a data signal quality detection signal from a modulator/demodulator in the multiplexing device connected to the modulation/demodulation devices which face each other while pinching the transmission line, and transmitting the signal to a host computer. CONSTITUTION:When the quality of the transmission line 3 is deteriorated, the modulator/demodulator 4 switches off the data signal quality detection signal SQD and informs the multiplexing device 5 of it. The multiplexing device 5 allots the time slot to inputted reception data RD and SQD, and transmits them to a multiplexing device 6. It separates transmitted RD and SQD and transmits them to the host computer 7. It judges the state of the signal SQD. When it is switched OFF, the computer judges that the quality of the transmission line 3 is deteriorated.

Title: Method for adjusting characteristic of microstrip antenna
Inventor: SHIBATA MASAKI
IPC: H01Q13/08
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To provide a new means for adjusting input impedance in a microstrip antenna and also to provide a characteristic adjusting method which suppresses the fluctuations of the input impedance due to the variations of the insulation intervals and makes the microstrip antenna have stable characteristics. SOLUTION: The input impedance can stably be matched to a 50 Ωfeeding line because the input impedance is adjusted by shifting the position of a feeding line 5 from the center of a dielectric substrate 2 by a prescribed quantity. Even though there is variations in the insulation intervals with the feeding line by positioning a feeding line in the aforementioned way, it is possible to suppress the effect to the utmost because the input impedance is made flat against the variations of the insulation intervals between a ground conductor 4 and the line 5 by shifting the position of the line 5 from the center of the substrate 2 by a prescribed quantity.

Title: Quantum well optical element
Inventor: SAKANO SHINJI
IPC: H01S5/34
Filed: 1992-11-09
Abstract: PURPOSE:To enable rapid modulation of a laser and low voltage driving of a modulator by using a semiconductor crystal which has a lattice constant larger than that of a substrate and generates compression strain inside a plane during epitaxial growth for a barrier layer constituting a quantum well. CONSTITUTION:When a strain-free crystal is used for a barrier layer, a depth of a well of a conductor 1 is shallow and a depth of a well of a valence band 2 is deep. Since an effective mass of electron 11 of the conductor is light, quantum level is formed in a place wherein energy level of a shallow well is high and overflow of electron to a barrier layer is easy to be caused. Meanwhile, when compression strain is used, the energy level of a well layer does not change and energy of a conductive band 2 of the barrier layer rises by DELTAEce and a depth of a well becomes deeper by the amount. Thereby, confinement of the electron 11 of light effective mass is improved and overflow to the barrier layer is reduced. According to this constitution, when leakage of carrier is reduced, quantum size effect becomes large, an oscillation threshold current is reduced and modulation velocity is improved simultaneously.

Title: Semiconductor integrated circuit device
Inventor: NISHI HIROAKI
IPC: H01L21/822
Filed: 1986-12-17
Abstract: PURPOSE:To contrive to shorten the lengths of wirings for shift and shift clock signal wirings by a method wherein the wirings for shift and the shift clock signal wirings are respectively previously ready-designed in a storage logical cell as master patterns. CONSTITUTION:Master-slave type FFs 4a-4m are arranged in cell arrays 2b-2f. The FFs 4a-4m are arranged being aligned laterally in the direction of a cell array 2a and the cell arrays 2b-2f for constituting shift registers. In case an automatic arrangement and an automatic wiring are performed utilizing a CAD, a wiring 5b for shift for connecting the shift registers constituted of the FFs 4a-4c and the shift registers 4d-4f being arranged in the array 2c needs a lateral track. Provided that, when a difference between the values of (x) coordinates, on which cells are positioned, is small, the length to occupy in the lateral track of a wiring 5e for shift becomes shorter, while shift clock signal wirings 8b and 9b are each connected between the shift registers 4a-4c and 4d-4b using a vertical track only. In such a way, the lengths of the wirings become particularly shorter.

Title: Image information read method and device
Inventor: KUWABARA TAKAO
IPC: H04N5/372
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To provide an image information read method and device employing an image detector of an optical read system to read image information that can employ an A/D converter with a small bit number and enhance the noise immunity at a lower level side. SOLUTION: The image information read method and device employs a detection amplifier of a log amplifier configuration that has an operational amplifier 351 and a transistor(TR) 352 whose collector 352c is connected to an inverting terminal (-) of the operational amplifier 351 and whose emitter 352e is connected to an output terminal (o) respectively. Since an output voltage characteristics of the detection amplifier has a higher gradient as a current level is lower and a smaller gradient as the current level is higher, the output dynamic range of this amplifier is smaller than that of a linear detection amplifier and even the use of an A/D converter with a small bit number can maintain sufficient resolution. Furthermore, a gain at a lower level can be increased more than that at a high level side resulting that the noise immunity at the lower level can relatively be enhanced.
