Title: Differential amplifier
Inventor: KOYAMA MIKIO
IPC: H03F1/26
Filed: 1992-08-24
Abstract: PURPOSE:To execute the active filter of low noise with a little current consumption by using both of the attenuation processing of a current gain due to a current mirror circuit and the linear range extension processing of an emitter coupled pair CONSTITUTION:When the ratio of the input current to the output current of a current mirror circuit 102 is set to n:1, a transconductance Gm is attenuated to 1/n. Then, a cut-off frequency f0 is turned to Gm/2pi.n.C as a ratio between Gm/n and a capacity value C and turned to 1/n in comparison with Gm/2pi.C. Therefore, currents i11, i12) and i13 to flow to emitter coupled pairs Q11Q12, Q13Q14 and Q15Q16 are made n-fold, and the equivalent input converting noise voltage is reduced to 1/n<1/2>. Therefore, noise from the filter can be reduced to 1/n<1/2> while keeping the capacity value C as it is. Further, the active filter of low noise can be executed with a little current consumption by using both of the attenuation processing of the current gain due to the circuit 102 and the linear range extension processing of the emitter coupled pair.

IPC: G11B5/85
Filed: 1983-11-29
Abstract: PURPOSE:To simplify a stage for forming a nonmagnetic layer and a magnetic layer on a base body and to improve the adhesion strength between the magnetic layer and the base body by forming a magnetic recording medium by an adhering stage to be executed in a gaseous atmosphere for making a metallic magnetic material into nonmagnetic and an adhering stage to be executed under the condition without said atmosphere. CONSTITUTION:Metallic materials, for example, Co-Ni alloy, etc. are heated to evaporate in crucibles 12, 13 to form vapor flow 14. A base body 6 is moved in a direction B and is subjected to vapor deposition in the crucible 13. Gaseous oxygen 15 is simultaneously fed thereto. The vapor flow is then oxidized to form a non-magnetic material which is deposited by evaporation on the body 6. An underlying layer 8 as a nonmagnetic layer is formed. The traveling direction of the body 6 is then changed to a direction A and at the same time the base body is subjected to the similar vapor deposition in a non-oxidative atmosphere by the crucible 12, by which a magnetic layer 7 is formed. The magnetic medium 5 formed in such a way is formed diagonally with crystal columns 9 of the layer 7, but the adhesion strength between the layer 7 and the body 6 is intensified by the adhesion power between the underlying layer 8 and the body 6 and the adhesion power between said layer 8 and the layer 7.

Title: Titanium dioxide pigment and its production
Inventor: TAKAOKA YOICHI
IPC: C09C1/36
Filed: 1992-07-31
Abstract: PURPOSE:To obtain a titanium dioxide pigment surface-coated with a lanthanum oxide film and being excellent in weathering resistance and dispersibility by neutralizing a lanthanum compound in a dispersion of titanium dioxide and drying the product. CONSTITUTION:The pigment is obtained by neutralizing a lanthanum compound in a dispersion of titanium dioxide, separating the obtained product, and drying it to surface-coat the titanium dioxide particles with an oxide of lanthanum. By surface-coating their weathering resistance can be markedly improved and the lanthanum oxide can coat densely and seal the particles. When the densely coated titanium dioxide pigment is added to a resin medium and the obtained mixture is formed into a film, the resin has little tendency toward decomposition due to the holes generated in the particles by ultraviolet irradiation, for the holes can be shielded by the dense coating film or for a like reason, which results in, for example, the marked improvement of the weathering resistance of the pigment.

Title: Measuring method for calcium silicate based amorphous hydrate
Inventor: YASUNAGA SUSUMU
IPC: G01N25/20
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To quantitatively measure a calcium silicate based amorphous hydrate CSH single quantity easily with high precision by separating a single waveform of the CSH from an endothermic waveform of a cement hardening body. SOLUTION: A sample of a cement hardening body is made and crystalline hydrate generated in the sample is identified. Absorbed heat values of hydrates generated by heat decomposition reaction in heating the sample are measured and respective waveforms are separated at the heat absorption peak of the respective hydrates in the sample. The CSH single absorbed heat value is found from the area of Lorentz waveform including heat absorption peak which is considered to be caused by the heat decomposition reaction of the CSH and divided by the absorbed heat value per CSH unit weight so that the quantity of the CSH is measured. The CSH single absorbed heat value is thus separated from the sum total of the absorbed heat values of the respective hydrates measured by heat analysis so that the CSH quantity can be quantitatively measured easily and accurately.

Title: Cathode-ray tube
Inventor: ICHIDA KOUSUKE
IPC: H01J29/48
Filed: 1987-09-09
Abstract: PURPOSE:To improve the spot formation and to make it possible to project an image of a high resolution and a good quality by avoiding to provide an electromagnetic quadrupole for correction on purpose at the outer periphery of a neck tube but providing the structure to divide a focus electrode into three to form an electrostatic quadrupole lens in a main electron lens. CONSTITUTION:In a main electron lens, an electrostatic quadrupole lens is composed of electrode parts G41 to G43 of a focus electrode which are divided into three parts. Although the section form of the electron beams B presents a circular form, the quadrupole effect is generated on the electric field distribution by the influence of an electron beam penetrating aperture h42 at the center electrode part G42 and the narrow widths of electron beam penetrating apertures h41 and h43 at both side electrode parts G41 and G43, when the periphery of the image screen is scanned, and the force to expand in the direction Y and to contract in the direction X is given to the electron beams B to make the section form in a long form in the longitudinal direction. Consequently, by correcting the wide spot at the periphery of the fluorescent screen 2 into the long spot by the quadrupole electric field at the focus electrode G4, the beam spot at the periphery is corrected to a spot form of about a circle.

Title: Method for reproducing musical piece
Inventor: MIYATA TOSHIHIKO
IPC: G11B20/02
Filed: 1989-08-31
Abstract: PURPOSE:To adjust a fade time by starting the attenuation of the sound volume of a reproduced musical piece in the case of the 1st change of a reproduced index and stopping the reproducing in the case of the 2nd change of the reproduced index. CONSTITUTION:Supposing that the musical piece is constitute of prelude, 1st accompaniment, interlude, 2nd accompaniment, interlude to (n)th accompaniment and postlude, 01, 02 to 2n-1, 2n and 2n+1 are respectively allotted to the values of corresponding index information. Then, the value X of an interval between the musical pieces is set as 00. When the value X changes from 2n-1 to 2n, that is, just after shifting to the interlude from the (n)th accompaniment, a fade-out control circuit 5 starts the fade-out of an audio signal reproduced from a CD reproducing device 1 by the use of a variable gain attenuator 2. In such a case, the audio signal is attenuated by 48dB for 5 to 6 seconds. Whether or not the value X is changed to 00 is examined, and the reproducing in the CD reproducing device 1 is stopped when the value X is 00, because 00 means the interval between the musical pieces. Thus, the fade time until reproducing is stopped is adjusted in accordance with the musical piece.

Title: Driving method for electrostatic ink jet head
Inventor: FUJII MASAHIRO
IPC: B41J2/14
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent the barrier wall between ink pressure chambers from being deformed during ink jet operation even if it is made thin through fine patterning. SOLUTION: Under a state where the diaphragm 51(2) of an adjacent nondriving nozzle 11(2) is attracted to an individual electrode together with the diaphragm 51(3) of a driving nozzle 11(3) in an ink jet head 1, an ink liquid drop is ejected from the driving nozzle 11(3). Subsequently, the diaphragm 51(2) is separated slowly from the individual electrode. Since the compliance of an ink pressure chamber 5(2) on the nondriving nozzle side is held low, the barrier wall 8(2) between the driving nozzle and the nondriving nozzle can be prevented from being deformed due to variation of ink pressure. Consequently, ink ejection characteristics can be prevented from deteriorating due to deformation of the barrier wall and high definition print operation with fine print quality can be realized easily.
