Title: Ssb modulation and demodulation system
Inventor: OGURO KAZUHIRO
IPC: H03C1/60
Filed: 1985-04-19
Abstract: PURPOSE:To improve the transmission efficiency of the transmission signal by providing a carrier wave which is reduced down to such a degree that satisfies the desired transmission efficiency at the transmission side. CONSTITUTION:A carrier wave of a low level is given to a single side band SSB modulation signal at a transmission signal so that the transmission efficiency is not deteriorated. This carrier wave is transmitted through a transmission antenna 6. While at a reception part 15, the transmission signal is received by an SSB receiver 9 via a reception antenna 8 and only the carrier wave in the signal is extracted through a band pass filter 10. This extracted carrier wave is amplifier by an amplifier 11 and supplied to an adder 13. At the same time, the main signal serving as the output of the receiver 9 is delayed by a delay circuit 12 and sunthesized with said extracted signal through the adder 13. Thus an output is obtained. The adder 13 produces an SSB signal having real number 0 point which can be applied by an amplitude controller from both input signals. Then the SSB signal is transmitted through an output terminal 14. Thus the high transmission efficiency is secured.

Title: Recording system
Inventor: SUGIURA SUSUMU
IPC: B41J2/21
Filed: 1982-05-17
Abstract: PURPOSE:To improve the image quality of a multi-nozzle color ink jet recording system, by subjecting recording parts to random or high frequency vibration in different directions with respect to the main scanning direction of recording to remove the irregularity in an image. CONSTITUTION:At every one row recording, a multi-nozzle head is moved over an arbitrary distance at a fine cycle in a direction same to the arranging directions of nozzles. For example, the half of a printing dot diameter is shifted at every one line. By this method, the gaps between dot rows 306, 307 are tangled and come to an inconspicuous form visually. In the case of a color image, if the moving distance of each dot toward the arranging direction of each nozzle is shifted at every color plate in order to superpose three colors or four colors, said gaps can be brought to an almost inconspicuous form. This recording system can be utilized not only in an ink jet recording system but in an electrophotographic recording system, heat sensitive recording and wire dot recording.

Title: Injection mold of optical molded body and molding method
Inventor: MAEDA KAORU
IPC: B29C45/37
Filed: 1990-03-29
Abstract: PURPOSE:To secure flatness and to precisely transfer the shape of a fitting part by forming the surface of a cavity for molding a mirror surface into the mirror surface and forming the surface for molding the rear into a roughened surface and forming the surface of the cavity becoming the reference plane of a holding means into the roughened surface and forming the surface becoming the rear into a smooth surface. CONSTITUTION:A molded body 1 is molded by an injection mold and the surface (a) of the molded body 1 is formed into an optical mirror surface. The fitting parts 2, 2' are formed to the upper parts of both edge side parts of the mirror surface part (a). The rear of the molded body 1 is formed into a roughened surface (b). The surfaces in the stepped parts of the fitting parts 2, 2' are formed into the same roughened surface as the rear (b). The rear side is formed into a smooth surface (c). When molten resin 3 is introduced into the forming molds 4, 5 and molded without thoroughly exerting the dwelling pressure, the adhesive force of molten resin 3 on the surface of the cavity is made weaker in the roughened surface side in comparison with the mirror surface side. Therefore sinks are concentrated in the roughened surface. On the other hand, in the terminals of the fitting parts 2, 2', sinks are concentrated in the part of the mirror surface (a) side. The mirror surface part secures the high-precision flatness free from sinks. The shape of the fitting part can be transferred and formed at high precision.

Abstract: PURPOSE:To improve fuel consumption of an engine at its cold state, by forming a cooling water chamber, partially provided to the external wall of an intake manifold while partially disclosed to a flow of exhaust gas, and feeding cooling water to said cooling water chamber through a temperature sensing valve. CONSTITUTION:At cold start of an engine, cooling water in a cooling water chamber 6 is at temperature not higher than a prescribed value, and a temperature sensing valve 11 is closed, then the cooling water in the chamber is rapidly increased its temperature because a plate-shaped wall member 5, especially a cup part 5a, is heated by exhaust gas flowing in an exhaust manifold 4. This cooling water transmits heat to heat receiving fins 3a of an intake manifold 3 to heat a wall part of the manifold and expedite vaporization of a mixture. If temperature of the water increases to at least a prescribed value, the temperature sensing valve 11 is opened, and the cooling water becomes flowing through the water chamber 6 to hold the temperature of the water to a prescribed value and prevent its overheat. Accordingly, fuel consumption at cold state of the engine can be improved to reduce a harmful component in exhaust gas further prevent deterioration of charging efficiency at a warmed state of the engine.

Title: Method for judging position of flaw detection for overhead-wire flaw detector
Inventor: MORI TAMAKI
IPC: G01N27/20
Filed: 1989-03-31
Abstract: PURPOSE:To make it possible to specify the accurate position for detecting flaw of an overhead wire by judging the position of the overhead wire where the flaw is detected only when both a front detecting coil and a rear detecting coil output detected signals at the same place on the overhead wire. CONSTITUTION:A coil frame 55 runs on an overhead wire 1 at a speed (v). At a time T1, a front detecting coil 50 detects a flaw at a point A and outputs a detected signal. The detected signal is outputted to a comparing means 62 after a delay time (t) has elapsed in a delay means 61. Meanwhile, after the time (t) has elapsed, the rear detecting coil 51 is positioned on the flaw at the point A. The coil 51 outputs the detected signal of the flaw at the point A to the comparing and judging means 62. At this time, the detected signal and the detected signal from the coil 50 are both inputted into the means 62 at the same time. The means 62 judges that both detected signals are at the specified level and outputs a judged signal corresponding to the level. Meanwhile, when the frame 55 passes a snow-proof ring which is attached to the wire, a detected signal is outputted when rollers 56 and 57 ride over the ring. Since the interval between both signals is less than (t) second, they are judged as noises.
