Title: Immersion nozzle for continuous casting
Inventor: SATOU NORIO
IPC: B22D11/10
Filed: 1980-12-02
Abstract: PURPOSE:To prevent the inclusion of powder in continuous casting by forming the section in the outside circumferential part of an immersion nozzle for continuous casting to a square or corrugated shape over the suitable range in the axial direction of the nozzle. CONSTITUTION:The discharge hole of a nozzle 1 is faced downward, and the shape of the section of the nozzle 1, that is, the shape in the outside circumferential part of the nozzle on which the flow of molten steel abuts is made as follows: the sectional shape of which the angle theta of the direction of the molten steel flow F4 diverged by colliding against the nozzle 1 and the molten steel flow F3 assumes >=45 deg. nozzle inside angle (the angle that it assumes to the central axis of the nozzle along the long sides of the molde). By the incorporation of such nozzle sectional shape, the molten steel flow F4 is collided against the inside wall 4-b of the mold, whereby turbulent flow is induced around the nozzle 1 and the collision against the opposite molten steel flow F3 is averted. By the avoidance of the collision, the generation of vortexes is prevented and the inclusion of powder is prevented.

Title: Digital sound recording device
Inventor: SAITO TORU
IPC: G11B20/10
Filed: 1987-07-07
Abstract: PURPOSE:To automatically make the level of an input analog signal optimum by controlling a multiplication factor value while comparing digitally a signal that the output from an A/D converter is multiplied by a factor with a digital signal containing a reference signal. CONSTITUTION:The digital signal Sd for level comparison is inputted to a level controlling means 40. Besides, the analog signal to be recorded is adjusted by a level adjusting means 13 so as to be somewhat large and after being digitized by the A/D converter, it is inputted to a multiplier 46. The multiplier 46 stores the output signal Sa of itself and the above-mentioned signal Sd for a duration necessitated for calculation and in addition, inputs the signal Sa to the controlling means 40. The means 40 obtains a comparison output corresponding to a level difference for the signal Sd and inputs the new factor value to the multiplier 46 through a factor adjuster 45, and the multiplier 46 executes a calculation for correction and outputs the signal Sa. This calculation is repeated, and when the level of the digital signal of a multiplied result comes optimum, the signal Sa is recorded by a recording part 17 through a round-off circuit 47, a digital signal processing circuit 15 and a high frequency map 16.

Filed: 1993-07-08
Abstract: PURPOSE:To prevent production of mis-correction and to attain high quality transmission while keeping a transmission efficiency by executing error correction decoding processing when an output of a reception quality detection circuit is excellent and stopping the processing when the output is deteriorated. CONSTITUTION:A received signal is demodulated by a reception demodulator 2 and a code discrimination device 3 makes code discrimination into binary data and the result is inputted to a signal processing unit 8. Furthermore, the reception signal is inputted to a reception level detector 6, sampled by an A/D converter 7 and inputted to the processing unit 8. The processing unit 8 compares a reception level sampling value with respect to the error correction word in the reception this time with a threshold level and executes error correction decoding processing to the word when the sampled value is larger than the threshold level, and does not execute the processing when smaller. Furthermore, the processing unit 8 stores the word subject to error correction decoding by the reception this time to a memory and outputs reception data to an output terminal 5 when all words forming a signal are subject to error correction decoding.

Title: Pulse width and amplitude determination system
Inventor: KATO TOMOKO
IPC: G01R29/02
Filed: 1990-06-27
Abstract: PURPOSE:To accurately determine the width and amplitude of an observed pulse by comparing the observed pulse with plural kinds of reference pulses which differ in pulse width and amplitude and determining the pulse width and amplitude of the reference pulse having the highest correlativity as the pulse width and amplitude of the observed pulse. CONSTITUTION:When a pulse width setting circuit 13 and an amplitude setting circuit 12 are adjusted to vary the pulse width and amplitude of the pulse waveform from a reference pulse generating circuit 11 in order, peak values of coefficients of cross correlation with the pulse width and amplitude are outputted by a dividing circuit 24 in order and stored in a storage circuit 25. A detecting circuit 26 detects the pair of the pulse width and amplitude whose peak value is maximum among the stored data and outputs them as the pulse width and amplitude of the observed pulse. Consequently, the pulse width and amplitude of even an observed pulse which has deformed complicate pulse waveform can be determined without inaccuracy.

Title: Optical transmission and reception device
Inventor: HIRAOKA SUSUMU
IPC: H04B10/524
Filed: 1985-07-30
Abstract: PURPOSE:To prevent cross modulation between channels due to the nonlinear distortion of a light emitting element without increasing required number of optical fibers by separating a frequency division multiplex signal into a residual side band amplitude modulation video signal, demodulating it to obtain the original plural video signals and sending them. CONSTITUTION:An optical transmission line 3 consists of optical fibers and sends the light from a light emitting element L1 to a photodetecting element L2 of a photodetector 2. The photodetector 2 uses the photodetecting element L2 being a photodiode or an avalanche photodiode to convert an optical signal sent through the line 3 into an electric signal, which is maplified by an amplifier AMP 2, fed to a demodulation circuit DEM through a band pass filter BPF 00 to obtain a frequency division multiplex signal. Then, the frequency division multiplex signal is fed to a low pass filter LPF 2 to obtain a base band video signal component Vo1, which is amplified by an amplifier AMPV1 to obtain the original video signal Vi1. Thus, the cross modulation due to the nonlinearity of an electrooptic conversion element is prevented and multi-channel signals are sent through a few optical fibers.

Title: Tool length measuring method
Inventor: UNNO MIKIO
IPC: B23Q17/22
Filed: 1987-07-10
Abstract: PURPOSE:To improve precision and reliability, by a method wherein a tool is axially relatively moved between a tool and a probe, and through repetition of measurement of a relative movement amount a plurality of times, unevenness in a measuring result is computed, and only when the computing result is below a given value, an average value of measuring results is calculated. CONSTITUTION:A tool 8 is moved to a position right above a probe 11, the tool 8 is lowered at a specified speed, and coordinate displacement (coordinate displacement from position at a reference height) at a point of time when a touch signal is outputted from a touch sensor 10 is measured to store it. Simultaneously, switching to return (rising) movement takes place, the tool is raised to a level being so high that output of the touch signal is rendered ineffective. The tip ports of the probe 11 and the tool 8 are cleaned by a cleaning device, and the above measurement is repeated again. Coordinate displacement is measured in a manner described above three times. When unevenness in the measuring result is below a given value, an average value of the measuring results is employed as measurement. Based on the average value, the height of the tool in a reference position serving as the length of the tool is calculated.

Title: Clock transfer circuit
Inventor: SUWA HARUO
IPC: G06F5/06
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent a long time slip due to jitter in a clock in the vicinity of a slip point. SOLUTION: When a read address of a buffer memory 2 is being deviated from, e.g. a central initially set area and enters a slip point detection area, a detection signal is outputted and the read address is automatically switched to an address in excess of a write address in a deviating direction from the detected address, that is, a point A or C at a lower end address of the area. Or the read address is switched to an area midpoint, that is, a point B at the detection of a first slip point, and switched to the point A or C in the same deviating direction at detection of 2nd slip point. Since the points A, C are selected with a margin to absorb phase jitter in a clock or the like with respect to the write address respectively, that is, to provide a hysteresis, the slip takes place only once and production of a long time slip is prevented.
