Title: Optical storage and reproducing device
Inventor: YONEKUBO MASATOSHI
IPC: G11B7/09
Filed: 1989-05-18
Abstract: PURPOSE:To reduce the subject device in thickness and yet to eliminate the need of control of a phase difference of polarization of reflecting mirrors by forming an optical path in one vertical step, providing two reflecting mirrors and canceling the phase difference of polarization to be generated by the reflecting mirrors respectively. CONSTITUTION:A beam 101 in the direction from a point light source to be incident upon galvanomirrirs is reflected by a 2nd reflecting mirror 103 of the galvanomirrirs having its rotary axis 102 in parallel with the beam 101, reaching the 1st reflecting mirror 104 along a seek direction. The beam is bent toward a position of an objective lens 105 and converged on an optical storage medium. Now, when the 2nd reflecting mirror is slightly rotated around the rotary axis 102, an incident angle upon the objective lens 105 can be altered, and the converged spot can slightly be moved in the orthogonal direction to a track on the optical storage medium. Then, the two reflecting mirrors 103 and 104 are composed of total reflection prism, and a phase difference of polari zation to be generated on each reflecting surface is canceled. By this method, the device can be reduced in thickness, and yet the need of control of the phase difference on the reflecting mirrors 103 and 104 can be eliminated.

Title: Magnetic recording device
Inventor: KOJIMA HIROAKI
IPC: G11B5/596
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording device easy to assemble and adjust by arranging an object lens so that a distance between the object lens for converging a light beam on a magnetic storage medium and the magnetic storage medium differs from the focal distance of the object lens. SOLUTION: Since an object lens 17 is arranged so that a distance between the object lens 17 and a magnetic storage medium 4 is shorter than the focal distance of the object lens 17, this makes a numerical aperture larger than a theoretic numerical aperture without making a spot diameter small on the magnetic storage medium 4, and makes SN ratio higher. When the numerical aperture is enlarged, a decrease in a quantity of light, which is caused by the fact that the magnetic storage medium 4 is tilted and thereby a part of returning light of a light beam 70 is shaded by an opening 2, is reduced, therefore, this makes assembly and adjustment easier to minimize the decrease in the quantity of light by the shading. To the contrary, the distance between the object lens and the magnetic storage medium may be set to be longer than the focal distance of the object lens.  Since the object lens 17 is arranged so that the distance between the object lens 17 and the magnetic storage medium 4 differs from the focal distance of the object lens 17, this makes the numerical aperture larger.

Title: Buffer circuit
Inventor: KAKEHI TATSUYA
IPC: H03F3/34
Filed: 1985-06-07
Abstract: PURPOSE:To suppress generating of an offset by using another transistor (Tr) to apply level shift in a direction cancelling the level shift of a Tr and making an output signal equal to an input signal so as to compensate the level error of the level shift. CONSTITUTION:The 3rd Tr 18, a current mirror circuit 20 and the 4th Tr 26 are installed. Then a current flowing to a Tr 8 is fed to the Tr 18 via the circuit 20. Since an input signal VIN is fed to the base of the Tr 18, a signal voltage whose level of the signal VIN is shifted is generated to the emitter in response to the current flowing to the Tr 8. The base voltage of the Tr 8 depends on the synthesized between the signal VIN and the base-emitter voltage of the Tr 4 and the collector current of the Tr 8 is decided. As the result, the signal voltage generated in the emitter of the Tr 18 is fed to the base of a Tr 26 and an output signal V0 being equal to the signal VIN is obtained from an output terminal 30.

Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce a pig iron production cost through the continuative use of plural alternative fuels under stable operation of a blast furnace by injecting plural kinds of fuels from the same tuyere. SOLUTION: For example, pulverized fine coal from a supplying system 3 for powdery fuel of the pulverized fine coal, etc., and tar from a supplying system 4 for liquid fuel of heavy coil, etc., are supplied, respectively and the pulverized fine coal and the tar are injected into the blast furnace 1 from the one tuyere 2. In the case of uniformly injecting the pulverized fine coal and the tar, the variation of blasting pressure is little and the operation is continued under stable condition without developing channeling, slip, etc. Further, in the case of stopping the supply of the tar, since it is unnecessary to change the injected tuyere, the adjustment of the fuel injecting quantity in each tuyere is unnecessitated, and the blasting action and the adjusting action of charging coke ratio can quickly be taken and the lowering of molten iron temp. is restrained. Furthermore, in the case of fixing the tar injecting quantity and increasing the pulverized fine coal, since the pulverized fine coal injecting quantity in the whole tuyeres can be increased by increasing the supplying quantity of the pulverized fine coal from the powdery fuel supplying system 3, the measures to this variation can quickly be taken.

Filed: 1979-09-28
Abstract: PURPOSE:To increase a sense speed by providing a sense amplifying circuit, using MOSFETs, with a digit line charging circuit which has a voltage sense input coinciding with the voltage sense input point of a sense amplifier. CONSTITUTION:In addition to MOSFETQ25, charging circuit B is provided which detects the potential of point A3, turns on Q25 when the potential of point A3 drops below a certain level and then precharges point A3 for a certain time. While point A3 is held at circuit threshold level INV.2 of inverter I2 and point A6 (digit line) is at level Low, applying signals Y and X to MOSFETs Q26 and Q27 respectively causes a momentary drop in potential to level Low at point A3 as shown by waveform A. Since the circuit threshold level of circuit B has been set to VB, circuit B generates a High-level output like waveform A8 for time tB and the output is applied to MOSFETQ23. As a result, point A3 is suddently precharged by Q23 for time tB, so that points A3 and A6 reach level INV.2. Consequently, point A4 is disconnected from the digit line rapidly, increasing the sense speed greatly.

Title: Method and device for bias ion plating
Inventor: MORITA SHINSAKU
IPC: C23C14/32
Filed: 1984-06-20
Abstract: PURPOSE:To prevent the surface of a substrate for vapor deposition from being flawed by electric discharge in the stage of depositing a film by ion plating to the substrate on which a bias voltage is impressed negative in a vacuum vessel by irraidating electron rays to said surface to neutralize the accumulated positive charge. CONSTITUTION:The substrate 17 is attached to a substrate holder 15 in a vacuum vessel 11 and plasma is generated in a vapor source 13 by the high-frequency discharge generated from a high-frequency oscillation coil 19 to ionize partly the evaportaing material from the source 13. The negative bias voltage is kept impressed to the holder 15 by a DC power source 35 in this stage to accelerate the ionized vapor in such a manner that the vapor collides against the substrate surface 17a thus forming the film deposited by evaporation. The positive charge accumulates on the surface 17a until the charge is discharged to make discharge traces on the surface for vapor deposition thereby deteriorating the quality of said surface, if the evaporating material is the insulating material such as SiO2 in this care. Thermion is therefore irradiated to the surface 17a to neutralize the accumulated positive charge, by which the generation of the discharge is prevented and the deterioration in the quality of the surface for vapor deposition by the discharge traces is prevented.
