Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To easily detect the fault of a communication network by transmitting monitoring signals to slave exchange parts by a master exchange part and gathering monitor signals generated by using the monitoring signals in the respective slave exchange parts. SOLUTION: Identification signal means 11A-11C transmit the monitoring signals, however, if the history of transmission or reception is present in all connected transmission lines, request the transmission of the monitor signals to monitor signal generation means 13A-13C without transmitting them, compare the collected monitor signals, the number of the slave exchange parts of the communication network and a communication network connection state and monitor a communication network form. For instance, the monitor signal initial values of the slave exchange part 4A are composed of the relay slave exchange part number data of 1, the monitoring signal number of 1, the relay slave exchange part number of 2, the relay slave exchange part number data of 2 and the monitoring signal number of 1.  For the monitor signal of the transmitted monitoring signal, the relay slave exchange part number data are 1 and the monitoring signal number is 1 and they do not match. As a result, the master exchange part 1 specifies an abnormal part and requests the detail data of abnormality to the slave exchange parts 4A and 4B.

IPC: G02F1/1335
Filed: 1995-01-23
Abstract: PURPOSE: To install a film for leak prevention with effectiveness in works by transcribing a photo-leak preventive film onto the specified surface of a photo-guide plate. CONSTITUTION: A back light BL to supply light to a liquid crystal display panel is composed of a lamp reflection sheet LS, cold cathode fluorescent tube LP, photo-guide plate GLB, diffusive sheet, reflecting sheet, and a prism sheet.

IPC: H01L29/06
Filed: 1979-01-29
Abstract: PURPOSE: To perform a surface-stabilization treatment, wherein deterioration in reverse-direction characteristics at high temperatures is less and working is easier in comparison with the method which protects the Si surface exposed by mesa etching with only an oxide film.  
     CONSTITUTION: A stained film is formed on the exposed surface of Si of the mesa portion by immersing a diode wherein a pn-junction is exposed at a mesa-etched surface 8 into a blended liquid of hydrofluoric acid and nitric acid. The stained film is heat-treated and a stable SiO 2  film is formed. Thereafter, the SiO 2  film is heat- treated in a vacuum, and a clean SiO 2  film 6 is formed. At this time, the degree of vacuum and the burning temperature are set at the specified values. After the burning treatment, an organic resin is immediately applied on the SiO 2  film 6 and dried, thereby a protection film 7 is formed. In this constituion, since the vacuum- burnt SiO 2  film 6 is protected from the contamination and damage in the subsequent processes, the characteristics of the reverse-direction current are not deteriorated even through the device is operated at the high temperatuer of about 150°C.

Abstract: PURPOSE:To stabilize an output and to enhance vibration resistance by constituting the signal paths of the angular-velocity signals generated between the electrodes of detecting piezoelectric elements with conductor paths using polyurethane-based silver paste and lead patterns provided on the surfaces of the electrodes of driving piezoelectric elements. CONSTITUTION:Detecting piezoelectric element 1 and 2 and driving piezoelectric elements are stacked and bonded with orthogonal intersection joints 5 and 6 so that the oscillating directions form a right angle. Silver electrodes 9a and 9b on the surfaces of the piezoelectric elements 1 and 2 and lead patterns 10a and 10b on one surfaces of the piezoelectric elements 3 and 4 are interconnected with polyurethane-based conductive silver pastes 8a and 8b. When an angular-velocity sensor receives an angular velocity, the piezoelectric elements 1 and 2 are deflected, and the electric charges are generated in the electrodes 9a and 9b. The electric charges are taken out of lead pins 13 through the conductive pastes 8a and 8b, the lead patterns 10a and 10b and lead wires 12 as signals. Since the conductive silver pastes 8a and 8b have elasticity, the pastes are not broken and do not hamper the deflection even if the detecting piezoelectric elements 1 and 2 are deflected.

Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of tracking accuracy by providing a first switch for selecting between the reflected wave of an electromagnetic wave radiated from a ground radar and the reflected wave of an electromagnetic wave radiated from its own transmitter. SOLUTION: When the distance to a target is long, an irradiation wave t1, i.e., a high frequency electromagnetic wave, is radiated from a ground radar R. A reflected wave r1 from the target is received by a first antenna 1 and amplified and then it is converted through a first frequency converter 10 into an intermediate frequency wave which is then amplified in order to detect an angle error signal. The output is delivered through a first switch 13 to a computer 14 where the relative speed to the target is calculated and a signal is delivered to a fuse 21 in order to fire a warhead 22.  At the same time, distance to the target is calculated and if it is shorter than a specified distance, the first switch 13 is switched to a second switch 5 and an irradiation wave t2 is radiated from a second antenna 2 toward the target based on the output from a transmitter before a predetermined processing is carried out.
