Title: Marine vessel speed measuring instrument
Inventor: NAGAO TAKASHI
IPC: G01S15/58
Filed: 1986-03-17
Abstract: PURPOSE:To perform secure tracking operation corresponding to abrupt geographic variation of the bottom of water and marine vessel speed variation by selecting a tracking gate according to the inclination of the bottom of water and the marine vessel speed. CONSTITUTION:Doppler shift detecting means 20 and 21 count waves of the wave bottom echo signal of an ultrasonic wave emitted into the water and a reference clock signal, outputs a counting end signal when the counted value reaches a set counted value, and detects a Doppler shift from the difference between counting end times. Further, AND gate circuits 38 and 39 which constitute a pulse width discriminating means decides that the water bottom echo signal has normal pulse width when the counting end signal is outputted within a constant sampling period, and sounding means 28 and 29 detects the depth. Then when a normalcy decision signal is outputted, an arithmetic means 30 calculates the marine vessel speed and tracking gate width from the Doppler shift and also computes the tracking gate start and end timing after the next transmission start from the tracking gate width and depth. Then, forward and backward tracking gate setting means 26 and 27 sets a tracking gate based on the tracking gate start and end timing.

Filed: 1990-03-08
Abstract: PURPOSE:To improve the echo suppression quantity by cancelling an echo linear component with a 1st echo replica generated by a linear component generating means and cancelling an echo nonlinear component with a 2nd echo replica generated by a nonlinear component generating means. CONSTITUTION:A linear component generating means 111 of an echo canceller cancelling the echo component caused by bypassing part of a transmission signal of a multi-value code to a receiver side generates and outputs a 1st echo replica having the linearity corresponding to various multi-value codes to cancel the echo component. A nonlinear component generating means 121 generates and outputs a 2nd echo replica corresponding to the difference between the echo component and the 1st echo replica. A cancellation means 131 subtracts the 1st and 2nd echo replicas from a reception signal to cancel the echo component. Thus, as a whole, both the linear component and the nonlinear component of the echo corresponding to the transmission signal of the multi-value code are constructed so as to cancel each other.

Title: Manufacture of molded thermoplastic resin article reinforced with gypsum fibers
Inventor: MORIKANE YASUMASA
IPC: B29C45/00
Filed: 1978-05-18
Abstract: PURPOSE: To obtain a molded thermoplastic resin article having inproved inpact resistance, ridigity, dimensional stability, and incineration property, by molding a blend of a molten thermoplastic resin with gypsum fibers and a lubricant.  
     CONSTITUTION: 100 parts by wt. of a molten thermoplastic resin, e.g. a polyolefin resin, is kneaded with gypsum fibers incorporated or covered with 0.1W10 parts by wt. of a lubricant having a melting point below the melt molding temperature of the resin, and the blend is molded. Prismatic or meedle-like crystals of α- hemihydrate or types I and II anhydrous gypsum may be cited as the gypsum fibers. The amount of the lubricant is preferably 200 parts by wt. or less per 100 parts by wt. of the resin due to the lowering of impact resistance by too much lubricant. If the amount is <0.1 wt.%, the gypsum fibers cannot be dispersed homogeneously in the resin. If the amount is >10 wt.%, the resin strength is adversely lowered.

Title: Picture quality correction circuit
IPC: H04N3/32
Filed: 1992-03-17
Abstract: PURPOSE:To reduce effectively a fog of a moving picture whose resolution is deteriorated in comparison with that of a still picture by selecting an amplitude of a speed modulation signal to a speed modulation coil with an output signal of a moving area detection circuit. CONSTITUTION:A video signal is fed to a base of a transistor(TR) Q9 via speed modulation signal synthesis use combined resistors R1, R2 and its amplitude is changed by a SW1 controlled to be turned on for a still picture and turned off for a moving picture by an output signal of a moving area detection circuit as shown in an output signal waveform. The degree of the change is set depending on a ratio of a resistance of a resistor R6 to the resistance of the resistors R1, R2. As a result, the amplitude of the speed modulation signal outputted from an emitter of the TR Q9 for a moving picture is larger than that for a still picture and the moving picture is subjected to larger speed modulation than the still picture. Thus, a trailing and a leading of the signal is corrected steeply and a fog of a video image is reduced.

Filed: 1988-03-15
Abstract: PURPOSE:To decode a teletext signal with an excellent characteristic by providing a characteristic conversion element converting the characteristic of a reproducing video signal processing system in the reception of a switching pulse into a characteristic suitable for decoding the teletext signal. CONSTITUTION:A characteristic conversion switch 35 and a characteristic conversion resistor 36 are connected in series and its series circuit is connected in parallel with a mid-frequency intensifying circuit 32. The value of the characteristic conversion resistor 36 is selected so that the characteristic of the output signal is made flat when the characteristic conversion switch 35 is turned on and connected to the circuit 32. Thus, when an edit switch 18 is not operated, the characteristic is regarded to be flat to the part corresponding to the period when the teletext signal of the video signal in the reproduced luminance signal is superimposed and the characteristic whose intermediate frequency is intensified as to the part where the pattern signal of the video signal is superimposed, that is, in other period, and the optimum characteristic to both the picture quality of the pattern observed on the screen and the decoding of the teletext signal is obtained simultaneously.

Abstract: PURPOSE:To simplify a circuit constitution by inputting the output signal of N latch circuits and inverting the phase of a latch clock signal when a coincidence detection circuit detects discordance. CONSTITUTION:A coincidence detection circuit 109 always decides the coincidence of outputs of D-F/F/1031, 1032 and judges that the output of the EX-OR gate 107 exists in the vicinity of the change point of a data input 101 when cordance is detected even once to invert the phase of the output signal of the EX-OR gate 107 automatically and the inverted clock signal is used to identify the data input 101 by using the inverted clock signal. The leading edge of the inverted clock appears when the data input is made stable to be a prescribed state, then it is possible to apply the retiming of the data input 101 without any error by using the clock signal, resulting that the data signal synchronously with the clock signal of the clock output line 111 appears on the data output line 110. Thus, the retiming of the data signal is attained without any error by having only to use a simple logic operation.

Title: Demagnetizing circuit
Inventor: TAMAASA KOUJI
IPC: H04N9/29
Filed: 1980-05-07
Abstract: PURPOSE:To obtain a demagnetizing circuit that causes no uneven demagnetization despite the use of two kinds of commercial power sources, by connecting a diode by-pass to a series circuit of a demagnetizing coil, a positive characteristic thermistor plus a resistance in parallel to the resistance. CONSTITUTION:With a commercial power source of 110V, the switches S2 and S0 are turned on and off, respectively. Thus a diode D0 gives no effect to a demagnetizing circuit, and symmetric current flows to the demagnetizing coil DG in the positive and negative half cycles of the input current. In the case of a power source of 220V, the switches S2 and S0 are turned off and on, respectively. As a result, the half-wave rectified current caused by a diode D1 flows to the route of 1-dot chanin line of (b) in the diagram. On the other hand, the current flows to the demagnetizing coil DG as shown by a solid line in the positive half cycle of the power source voltage, and the current flows as shown by a broken line in the negative half cycle. Thus an unbalance for the demagnetizing current in each half cycle can be corrected by setting the value of resistance R at a proper level.
