Title: Motor speed control circuit
Inventor: WATANABE KENJI
IPC: H02P6/12
Filed: 1994-04-05
Abstract: PURPOSE:To prevent a motor from rotating improperly due to noise by shaping the waveform of a speed signal into a binary pulse signal, performing feedback control so that the period of the pulse signal is at a specific reference time, and at the same time selectively eliminating a pulse with a certain duty width or less. CONSTITUTION:After the waveform of a speed signal Vs is shaped into a binary pulse signal V1, a pulse with a certain duty width or less is selectively eliminated by a digital noise elimination circuit 26. An output pulse signal V2 of the digital noise elimination circuit 26 is input to a speed control logic 27. The speed control logic 27 performs feedback control of the amount of drive (drive current) of a motor 1 so that the cycle of the trailing edge of the input pulse signal V2 is the same as a specific reference time created based on a reference clock f0, thus performing feedback control of the motor 1 to a specific speed and hence positively preventing the rotation disturbance of the motor 1 due to noise.

Title: Ink feeder of print head
Inventor: NIERUSU JIEE NIERUSEN
IPC: B41J2/175
Filed: 1987-03-20
Abstract: PURPOSE:To prevent the leakage of ink, by a method wherein the weight of an ink fountain is made to be negligible by comparing it with the weight of the ink feed amount in the ink fountain. CONSTITUTION:An ink fountain 2 is connected to a print head 1 by a flexible pipe line and the ink fountain 2 is made from light thin wall materials like ABS resin. The one end of the bridge structure 2a bridging the upper part of the ink fountain 2 is connected to the bottom end of a tensile spring 9 and so supported that the ink fountain 2 can be freely moved. The weight of the ink fountain 2 is so lightened as to be negligible by comparing it with weight of ink contained therein. The depth (h) of ink in the ink fountain 2 becomes shallow as ink is continuously fed and the level of the ink fountain 2 rises. Therefore, the hydrostatic head H between a fulcrum 10 and the surface S of the ink is kept constant. The surface S of the ink in the ink fountain 2 is kept below the center line of the opening part array in an orifice board 5 and the back pressure of the opening part becomes slightly negative. Thereby, ink is prevented from oozing out from each opening part while the print head 1 is not used.

Title: Al alloy for substrate of magnetic disk
Inventor: YAMADA KAZUO
IPC: G11B5/62
Filed: 1983-04-18
Abstract: PURPOSE:To reduce the size and weight of a magnetic disk and to improve the magnetic recording density by specifying the percentages of Al, Mn, Mg, Zn and inevitable impurities contained in an Al alloy so as to increase the strength. CONSTITUTION:This Al alloy consists of, by weight, 0.1-0.5% Mn, 3.0-5.0% Mg, 0.5-3.0% Zn and the balance Al with inevitable impurities including <=0.20% Si, <=0.50% Fe, <=0.30% Cu, <=0.05% Cr, <=0.04% Ni and <=0.01% Ti. Mn, Mg and Zn can remarkably increase the hardness and strength of the alloy, and Si Fe, Cu, Cr, Ni and Ti as inevitable impurities each form an intermetallic compound. Since the Al alloy having said composition has high hardness, when it is used as the material of the substrate of a magnetic disk, the surface can be converted into a much superior mirror finished surface by buffing in a relatively short time. Intermetallic compounds present in the matrix are fine and uniform, and nonmetallic inclusions have been removed by filtering molten metal or by other means, so the thickness of a magnetic recording medium can be reduced.

Title: Amplifier for optical reception
Inventor: MIKAMURA YASUKI
IPC: H03F3/08
Filed: 1989-03-20
Abstract: PURPOSE:To suppress the waviness in the output characteristic by varying a resistance between a cathode of a photodetector and a bias source so as to vary the capacitance of the photodetector equivalently. CONSTITUTION:A resistor RD is connected in series with a capacitor CB and a cathode of a photo diode PD and bias supply power terminals Pa-Pc are connected via a series circuit comprising resistors RB1-RB3. When an element with a small capacitance as the photodiode PD is used, the band of a receiver depending on the input impedance of the receiver and the input capacitance such as a photo diode capacitance is extended and close to the base of an amplifier 2 itself and the waviness of the input impedance appears at an output of the amplifier 2. When the feedback element comprising a resistor RD is inserted, the equivalent capacitance reduction effect of the photo diode PD due to bootstrap is partly sacrificed and the waviness of the output characteristic is obviated.

Title: Transmitting device for digital signal
Inventor: OKUMURA MASAHIDE
IPC: H03M1/66
Filed: 1991-04-01
Abstract: PURPOSE:To reduce a noise accompanied with the change of a digital signal by transmitting the content of a designated register through one system line driver to a computer or an analogous equipment. CONSTITUTION:The above device is equipped with a computer 11, plotting control part 1, electronic beam mirror body 10, line receiver 4, register 5, D/A converter 3, selecting part 8, and line driver 6. Then, the content of one arbitrary register of the registers 51-5n is read and selected by a multiplexer, and this result is returned through the one system line driver 6 to the plotting control part 1. Therefore, only one system is sufficient for the line driver 6 for returning a signal to the plotting control part 1, so that the possibility that the analog output of the D/A converter 3 is directly and indirectly vibrated by the change of a digital signal, and that the temperature drift of the D/A converter 3 causing the rising of the temperature is generated can be reduced by half.

Title: Vertical magnetic head
Inventor: SUMIYA KAZUHIKO
IPC: G11B5/127
Filed: 1984-04-05
Abstract: PURPOSE:To obtain a vertical magnetic head which is easily manufactured, excellent in the magnetizing efficiency, and improved in the recording sensitivity, by winding a coil around a projected part at the center of a high-magnetic permeability magnetic substance body which is magnetically coupled with one end of a main magnetic pole. CONSTITUTION:A main magnetic pole 10 of a soft magnetic thin film is held between base bodies 11a and 11b and a high-magnetic permeability magnetic substance block 30 worked to have a projecting shape is joined with them so that the block 30 can be connected magnetically with one end section of the main magnetic pole 10. A coil 20 for recording and reproducing is not wound around the main magnetic pole 10 but around a projected part at the center of the block 30. Therefore, the coil can be wound easily. Moreover, since no magnetic saturation takes place at the section beyond the front end of the main magnetic pole 10, this vertical magnetic head becomes excellent in magnetizing efficiency. As a result, the front end of the magnetic pole is intensely magnetized and the recording sensitivity can be improved.
