Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a small pedestal member enough, by forming vertical parts of inner conductors by printing a conductor layer, the conductors are provided for connecting either the conductor layer formed at the center or those formed at the right and left of the member. SOLUTION: A small pedestal member 10 has a protrudent central part 17 with a right and left flat parts lower than the part 17. A top step conductor layer 11a is formed on the top face 11 of the central part 17, a grounding conductor layer 12a is formed on the left lower step face 12, and a lower step conductor layer 13a is formed on the right lower step face 13 and extends into the central part 17. The lower and top step conductor layers 13b, 11a are connected through a connecting conductor layer 14 composed of a thin plate formed by the printing. This reduces the area of the top step conductor layer 11a to a very small value, thus realizing a greatly reduced size.

Inventor: KASHIYUU KEIICHIROU
IPC: H04L27/20
Filed: 1979-01-22
Abstract: PURPOSE:To narrow the band width of each channel by making the phase modulation of a carrier even when no PCM signal arrives by phase-modulating the carrier by the PCM signal while doing that by a false signal when no PCM signal arrives. CONSTITUTION:A PCM signal from PCM signal input terminal 1 is code-converted by logic circuit 4 and then supplied to OR circuit 7 by way of LPF6. Further, the PCM signal is supplied to existence decision circuit 5 to decide on the existence of the PCM signal and when no PCM signal arrives, a false modulated signal is generated and applied to circuit 7, the output of which is applied to carrier suppressing/ balancing modulation circuit 8 for phase modulation of a carrier, thereby outputting a phase-modulated PSK signal via PSK signal input terminal 3. Then when there is no PCM signal, decision circuit 5 generates the false modulated signal and circuit 8 phase-modulates the carrier to transmit a signal with the band width of each channel narrowed.

Filed: 1984-01-18
Abstract: PURPOSE:To enable detection with good accuracy even with an object to be exposed having low-stepped patterns for detection by selecting automatically the larger gain of the gains of the waveform components detecting the recessed and projecting patterns on the object and detecting the relative position between the object and an original picture. CONSTITUTION:A projecting pattern 61 for detection and a recessed pattern 62 are formed on a substrate 42 of a wafer applied thereon with photoresist 41. The reflected images of both patterns 61, 62 are optically detected. The differences OG and TG between the max. value and the min. value based on the equations are determined from the waveforms XOh(I), XTh(I) which correct and calculate the waving, etc. of the waveforms XO(I), XT(I) detecting the respective patterns 62, 61. The waveform XO(I) is automatically selected for superposition for the purpose of detecting the relative position of the wafer which is the object to be exposed and the original picture when the differences OG, TG are OG>TG and the waveform XT(I) is selected if OG<TG. The probability of generating a difficult detection in which both differences OG and TG are made zero is decreased by such selection and the pattern is exactly projected and exposed to the wafer.

A variable valve timing mechanism (VVT) 50 is so controlled that the intake air pressure may be between the lower limit intake air pressure and the upper intake air pressure when an internal combustion engine 10 is judged to be in the decelerating state. Accordingly, the pressure in the intake passage 20 is not maintained in the considerable low state even when the intake air pressure in the intake passage 20 is decreased, and oil rising wherein engine oil is sucked into a combustion chamber 15 is restrained.

Title: Engraving head
Inventor: NISHIMURA HIROTAKE
IPC: B44B5/00
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an engraving head for a gravure engraving system for damping an excess vibration of a diamond cutting tool with good durability without depending upon an ambient temperature and further rapidly vibrating the tool. SOLUTION: When a shaft 103 is vibrated, a conductive plate 11 fixed to the shaft 103 is vibrated in a direction of an arrow (d), and the plate 11 crosses a magnetic flux changing in a short side direction of a length L1. Accordingly, a Lorentz force of a reverse force to a moving direction of the plate 11 is generated in the plate 11. A magnitude of the force is proportional to a moving speed of a diamond cutting tool 101. Therefore, the tool 101 relatively rapidly moves due to its transient response at a part in which a stepwise density signal abruptly changes to tend to overshoot, but a magnetic damper rapidly attenuates the overshoot of the tool 101 with the force as an attenuating force.

Abstract: PURPOSE:To have a power supply circuit, to be used for ignition of an internal combustion engine, which assures sure rotation control of engine, by operating a semiconductor opening/closing element using the output of power supply circuit and thereby increasing the power supply current. CONSTITUTION:When a number-of-revolutions sensing circuit 24 operates, a transistor 29 is turned from off to on while a one 31 is formed on to off, to put a semiconductor opening/closing element 33 in continuity. Because the current in a charge coil 1 is thus impressed to the power supply circuit through a resistance 34 and a diode 35, supply of the power is secured even in the condition in which the voltage at the ignition coil 9 is shortcircuited. Thus the number-of- revolutions sensing circuit 24 is capable of operating continuously, so that the transistor 26 maintains its state of continuity to cause distinction perfectly. Accordingly control of the number of revolutions of the engine is ensured.
