Title: Multilayer interconnection circuit board
Inventor: HIROTA KAZUO
IPC: H05K3/46
Filed: 1988-07-06
Abstract: PURPOSE:To obtain a high-density and multilayer circuit board by using a thick-film and thin-film hybrid substrate and by making the maximum value of signal wiring length in thin film smaller than that of signal wiring length in thin-film. CONSTITUTION:When wiring becomes thinner, conductor resistance becomes higher and signal is attenuated according to exp[-R.l/2 Z0] and does not exceed the threshold. Z0 is characteristics impedance, R is resistance, and l is wiring length. Wiring length of wiring substrate is generally short. Also, generally in precision wiring made by optic processing, wiring resistance becomes relatively large as compared with thick-film resistance. For example, although resistance of a copper wiring with a width of 20mum and a thickness of 2mum is 5ohms/cm or more, resistance of W wire with a width of 100mum and a thickness of 10mum is 1ohms/cm or less and wiring can be made only as much as 1/5 the length of thick-film. W thick-film wirings 2 and 3, thin-film insulation layer 4, and a copper thin-film wiring 5 are piled up on an alumina ceramics 1, allowable amount of signal attenuation is determined, high integration by a thin-film and low-resistance wiring by a thick-film can be made to allow a high-density multi-layer substrate to be formed while retaining transmission characteristics.

Filed: 1989-06-30
Abstract: PURPOSE:To enable detection of a distance to a target and a speed of movement thereof only by one inexpensive and nondirectional passive sonobuoy, by determining a change with time of a Doppler frequency of a sound emitted by the target observed. CONSTITUTION:An underwater sound caught by a nondirectional passive sonobuoy 1 is delivered to a frequency analyzing element 2 by using a VHF band or the like, converted from data in a time area into data in a frequency area by using Fourier transform or the like, and supplied to a target sound specifying element 3. Based on the result of analysis of the analyzing element 2, the specifying element 3 specifies the frequency of the sound emitted by a target and supplies said frequency to a computing element 4 of a distance to and a speed of movement of a sound source. The frequency on the occasion is subjected to Doppler displacement corresponding to the relative speeds of the target and the passive sonobuoy, and a Doppler frequency changes with time. Based on the frequency subjected to the Doppler displacement, subsequently, the computing element 4 can calculate the distance to the target and the speed of movement thereof from the sound caught by the inexpensive and nondirectional passive sonobuoy 1.

Title: Radio transmitter-receiver
Inventor: TERUI KOKI
IPC: H04L25/02
Filed: 1990-06-26
Abstract: PURPOSE:To interrupt noise produced from a receiver from being reflected back to a transmitter by sending a device fault alarm signal to a control circuit when a fault of each section of the receiver is detected so as to interrupt the connection of a base band loop switch circuit. CONSTITUTION:In the case of conducting a loopback test, a base band loop switch circuit 1 acts to make loopback connection between a receiver and a transmitter, a device fault detection circuit 3 monitors a fault alarm from a reception high frequency section 5, a demodulation section 6 and a reception signal processing section 7 and sends a device fault alarm signal to a control circuit 2 so that the loopback connection of the base band loop switch circuit 1 is forcibly interrupted when a fault is detected. The device fault alarm signal takes preceding of the control of the control circuit 2 over a control signal from a control signal input terminal 12. Thus, when noise takes place on the occurrence of a fault of the receiver, a defect of loopback of the noise to the transmitter is avoided.

Title: Image processor
Inventor: KAWASE MICHIO
IPC: H04N1/46
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To eliminate color slurring and color unevenness without causing uneven pitch by varying at least one line density from the others in the case of forming an image from each image signal when one image is expressed by plural image signals. SOLUTION: The processor is provided with a comparator 3 that compares an analog color image signal outputted from a D/A converter 1 with a pulse pattern outputted from a pulse pattern generator 2 to conduct pulse width modulation(PWM) and an amplifier 4 that amplifies a PWM signal outputted from the comparator 3. Then the comparator 3 modulates a picture signal so that a line density in the case of forming an image of the picture signal in at least one color or over among picture signals in plural colors differs from a line density in the case of forming an image of the picture signals in the other colors.  Since a picture element in duplicate among colors and a picture element not in duplicate are produced for a short period, uneven color for a long period due to uneven rotation of a polygon mirror is eliminated and a color change in a picture even on the occurrence of a color slurring is prevented.

Abstract: PURPOSE:To provide a delay control circuit which can facilitate the circuit layout and can prevent the jitter of an output signal by adding two output terminals to each gate circuit to make one of these two terminals touch a multi-input OR circuit and to connect the other terminal to the gate circuit of the next stage. CONSTITUTION:Each gate circuit 5 contains an input terminal and two output terminals. One of these two output terminals is connected to the input terminal of a multi-input OR circuit 4, and the other output terminal is connected to the input terminal of another circuit 5 of the next stage. The selection signals B0-Bn are inputted to the circuit 5 from a control circuit 1 to select an output terminal that outputs the signal inputted to the circuit 5 as an output signal. A decoder 1 outputs the output signal of a certain circuit 5 to the circuit 4, and other circuits 5 output the signals B0-Bn to output the output signal to each circuit 5 of the next stage. Then an input signal IN is inputted to the input terminal of the circuit 5 of the first stage and an output signal OUT is outputted through the output terminal of the circuit 4. Thus it is possible to facilitate such a layout that can shorten the wiring length of each circuit 5.

Title: Sealing system of optical waveguide
Inventor: WADA ICHIROU
IPC: G21C17/00
Filed: 1982-09-27
Abstract: PURPOSE:To obtain a seal which scarcely causes an optical loss and has a high stability by providing a seal part which takes a thermal factor and an optical quality into consideration, on a boundary wall penetrating part being in different physical and chemical conditions. CONSTITUTION:Areas A, B are under physically and chemically different conditions, and are isolated by a boundary wall 11. An optical waveguide for transmitting optical information is led into the area B from the area A and vice versa. A penetrating part is formed on the boundary wall 11, an optical waveguide 12 is led in, and a seal part 13 is formed on the outside circumferential part. As for an optical refractive index of a seal material, that of a value which is below an optical refractive index of the surface of the optical waveguide is used, and as for a coefficient of thermal expansion, it is set to a value between coefficients of thermal expansion of an optical waveguide material of the optical waveguide 12 and a boundary wall material of the boundary wall 11, by which the amount of a thermal strain which is the cause of an optical loss can be reduced. When light is made incident to a substance whose refractive index is small from a substance whose refractive index is large, light which is made incident by an incident angle exceeding a critical angle is totally reflected. Light which escapes from the optical waveguide generates a component which is totally reflected between the seal part and the surface of the optical waveguide and is made incident to the optical waveguide again, and the amount of loss of light is reduced remarkably.

IPC: H04W88/02
Filed: 1994-07-20
Abstract: PURPOSE:To provide a communication system capable of starting an internal circuit by allowing a mobile communication equipment to detect accurately to enter a communication available zone with a stationary communication equipment. CONSTITUTION:In the communication system making communication between a stationary station and a responder mounted on an automobile, the stationary station sends a start pilot signal for a prescribed period. Then the responder uses a detection section 22 to detect a reception signal from an antenna 10 and amplifies the signal by an amplifier section 24 and when a signal level after amplification reaches a reference voltage VTH1, a level discrimination section 26 outputs a pulse signal. Then a discrimination pulse generating section 28 converts the pulse signal into a signal whose width is constant and allows an integration section 30 to integrate the signal and when the integration value reaches a reference voltage VTH2, a start discrimination section 32 provides an output of a drive signal for starting the internal circuit. As a result, erroneous start of the internal circuit is prevented on the occurrence of intrusion of noise and then the internal circuit is started accurately only as required.
