IPC: B41J2/015
Filed: 1987-01-08
Abstract: PURPOSE:To perform the dense mounting of an ink particle generating part and to carry out gradation recording of a dot unit, by separating a heating part lowering the viscosity of ink by selectively heating the ink from a pressure generating part forming the ink into particles by applying pressure to the ink lowered in its viscosity. CONSTITUTION:Ink passes through an ink supply passage 8 from an ink supply part, and is supplied to a common ink chamber 2. A piezoelectric element is used in a common pressure generating part 3 and voltage is applied thereto corresponding to a printing fundamental clock signal. By this mechanism, a pressure wave is generated in the common ink chamber 2 and propagated to the ink in the vicinity of the nozzle part of a jet orifice. When a current is selectively supplied to a heating part (resistor) 5 in synchronous relation to the aforementioned fundamental clock in this state, only the ink filling a nozzle corresponding to the heating part (resistor) 5 to which a current is supplied rises in its temp. to be lowered in its viscosity and said ink is formed into a particle by the above mentioned pressure wave to fly. since the heating part 5 can be finely formed by sputtering or etching, a large number of nozzles can be densely mounted in a line form.

Title: Compound magnetic head
Inventor: NAKAGAWA YOSHIJI
IPC: G11B5/23
Filed: 1978-01-13
Abstract: PURPOSE:To suppress pseudo-gap action of magnetic material junction part and achieve the improvement in S/N by constituting respective magnetic cores in tape contact face with two kinds of magnetic materials and making the junction face thereof non-parallel to the length direction of a magnetic gap. CONSTITUTION:Pole pieces 3, 3' having a recording-reproducing gap 4 are composed of Sendust, monocrystalline ferrite, etc. of high saturation magnetic flux density and yoke parts 5, 5' composed of ferrite, etc. of lower saturation magnetic flux density than that of the pieces 3, 3' and higher effective magnetic permeability. The junction faces c'-c and e'-e of both materials are so constituted as to respectively assume an angle thetaA to gap face g-g' on the tape sliding face. Hence, even if a slight gap that cannot be avoided is produced on the junction faces, the reproduction sensitivity as a pseudo-gap is reduced as much as azimuth loss as compared to those having the junction faces parallel to the lengthwise direction of the gap. Thereby, suppressing pseudo-gap action, S/N may be improved.

Title: Signal processing method of optical detector for the surface flaw of steel band
Inventor: SANNOMIYA SHIZUYOSHI
IPC: G01N21/89
Filed: 1978-01-17
Abstract: PURPOSE:To detect the surface flaw in excellent S/N ratio by storing the optical detecting signals of the surface of a moving steel band in a latch and memory in synchronism with the scanning so that they may be subjected to arithmetrical mean. CONSTITUTION:The surface of a moving steel band 11 is optically scanned through reflection and scattering to detec a flaw 12. The signals TIN synchronized with the scanning detection signals DIN are used to set at FF1 through a monostable multivibrator MM1 so that the clocks of an oscillator OSC are counted of a half frequency dividing counter CT1. The signals DIN are subjected to digital conversion by the monostable multivibrators MM3 to MM5 and an address counter CT2 at the sample hold circuit S/H and A/D converter in synchronism with the scanning operation. After the signals are latched consecutively through the RAMM1 to M2 by latch circuits L2 to L5. The resultant valuse are subjected to arithmetrical means by adders FA1 to FA3. As a result, the random noises N are subjected to that means n times to n<1/2>N. Thus, S/N is reduced to n<1/2> so that the detection of the surface flaw can be detected with substantially excellent S/N ratio.

Filed: 1979-01-16
Abstract: PURPOSE: To detect accurately the slag passing start point into nozzle, by bringing the probe coil close to the ladle nozzle, and detecting the damping start point of lift-off fluctuation electric signal occurring in the coil along with vibrations of the nozzle.  
     CONSTITUTION: When pouring molten steel 10 in a ladle 30 into a continuous casting facility 40, a driving device 50 is operated when slag 11 is about to approach the ladle bottom so as to bring a probe coil 44 close to a nozzle 12, and the coil is excited by passing a constant current at fixed frequency. When the molten steel passes through the nozzle, the nozzle vibrates to fluctuate the distance between the coil and molten steel, thereby generating a lift-off fluctuation electric signal, which is detected in a detecting device 48. Since the signal is damped suddenly when the slag flows into the nozzle, a cylinder 32 is automatically operated by a control  signal from the detecting device, thereby closing a gate 34.

Abstract: PURPOSE: To simplify the constitution of an optical system and a selecting mechanism for readout tracks, by selecting a lens opposing to a desired track from a lens array opposed to a disk surface and by causing a readout light beam to strike it.  
     CONSTITUTION: On concentric tracks 3-1, 3-2,... on disk 1, information patterns 2 formed of substances differing in reflectivity are drawn. Disk 1 is rotated by motor 4, and light from semiconductor laser 5 is converted via collimating lens 6 into a parallel beam, which is caused to strike one lens in lens array 7, so that a corresponding track will be irradiated. Reflected light from the track is intensity-modulated according to variation in pattern 2 and incident to laser 5 after traveling back via the incident path. Therefore, the output of laser 5 varies with the quantity of the incidence of the reflected light, and the variation is detected by photodetector 8 to obtain an encoded signal.
