Title: Optical information-recording medium
Inventor: KOYAMA EIJI
IPC: G11B7/243
Filed: 1986-02-04
Abstract: PURPOSE:To obtain an optical information-recording medium having high recording sensitivity and excellent preservation stability, by providing a recording layer comprising at least bismuth oxide and substance capable of being activated when being irradiated with optical energy to react with the oxygen atom in the bismuth oxide thereby forming a gas. CONSTITUTION:A disk base 1 is formed from an inorganic material such as a glass or from a transparent plastic material such as polymethyl methacrylate, a polycarbonate, an acrylic resin and an epoxy rein. A recording layer is formed of a mixture comprising at least Bi2O3 and Bi2S3. When this optical information- recording medium is subjected to recording, Bi2O3 and Bi2S3 react with each other to produce an SO2 gas, and evaporation of melted Bi is accelerated by the pressure of the gas. Accordingly, recording sensitivity can be enhanced as compared with that of a conventional optical information-recording medium in which holes for recording information are formed by utilizing only a thermal deformation of the recording material itself.

Inventor: YOSHIDA NORIYUKI
IPC: H02P7/29
Filed: 1982-02-13
Abstract: PURPOSE:To eliminate the erroneous operation of a motor at the energizing or interrupting time of a power source by forcibly interrupting switch means for controlling the power supply to the motor when a controlled power source is not in an ordinary state and the control signal produced form the control circuit does not reach the prescribed level.

When the drive power source becomes possible to supply power prior to the controlled power source at the moment when the main switch is closed in the controller, a transistor 78 is conducted by the drive power source without waiting the output of the comparator 63, and a power transistor 80 is interrupted. Even when the main switch is opened, the erroneous operation can be similarly prevented.

Title: Magnetic disk device
Inventor: TANAKA YOSHITAKA
IPC: G11B21/12
Filed: 1984-02-09
Abstract: PURPOSE:To prevent the destruction of a magnetic head and damage of a disk plate by detecting obstacles to the magnetic head on the disk plate before accessing data. CONSTITUTION:When an obstacle 7 exists at any place on a magnetic body 5, it is detected by a photo-electric conversion light receiver 2 as interception of light generated by a semiconductor light source by turning the disk plate 3 around a rotation axis 4. When the light receiver 2 detects interception of light due to such an obstacle, a magnetic head driving device is controlled by the interception signal to retreat the magnetic head 6 from the disk plate 3. Thus, the destruction of the magnetic head 6 due to collision of the obstacle 7, is prevented and the magnetic head 6 is prevented from being dragging by the obstacle 7 and damaging the magnetic body 5.

Title: Optical-beam scanner
Inventor: ONO SHUJI
IPC: H04N1/113
Filed: 1988-02-02
Abstract: PURPOSE:To correct the deviation of a scanning line caused by face tilting, etc., with a simple constitution by again projecting the optical beam reflected by an optical deflector to the optical deflector through a cylindrical lens and reflection mirror. CONSTITUTION:The optical beam 2 reflected by a rotating polygon mirror 4 is converged to a reflection mirror 6 through a cylindrical lens 5 and reflected by the mirror 6. The reflected optical beam is again passed through the lens 5 and made incident on the polygon mirror 4. The spot where the optical bream is again made incident is different from the spot where the optical beam is previously made incident. The optical beam again reflected by the polygon mirror 4 always form an optical path which is parallel to the optical beam made incident on an optical deflector 4 first in the plane where the correction is performed. Therefore, even when the optical path of the deflector 4 deviates from the initial optical path due to axis shifting, face tilting, etc., the optical path of the finally reflected optical beam always becomes parallel. Accordingly, when the lens 5 and mirror 6 are provided by one each, deviation of a main scanning line can be prevented.

Title: W/o bituminous emulsion
Inventor: HAYASAKA HIROSHI
IPC: C08L95/00
Filed: 1984-02-13
Abstract: PURPOSE:To provide a W/O bituminous emulsion which well penetrates into the interior of roadbed without causing environmental pollution or any troubles and can increase waterproofness of the surface of the roadbed, by emulsifying an oil phase consisting of a bituminous substance, a solvent and a nonionic surfactant and a water phase consisting of an aq. alkaline soln. CONSTITUTION:A W/O bituminous emulsion is obtd. by emulsifying an oil phase consisting of a bituminous material (e.g. straight asphalt), a solvent (e.g. petroleum naphtha) and a nonionic surfactant (e.g. sorbitan monooleate) and a water phase consisting of an aq. alkaline soln. (e.g. an aq. magnesium hydroxide soln.). Disadvantages such as malodor and toxicity inherent to cutback materials as conventional primer coating material can be eliminated by the use of the solvent and accidents such as fire hazard can be prevented by the use of water. Unlike O/W bituminous material, the breaking of the emulsion is not caused by the contact of the emulsion with an aggregate. Since hardening is caused by the evaporation of the solvent and water, a film is hardly formed by curing on the surface of a roadbed and hence, the emulsion penetrates deeply until it is hardened. Accordingly, the emulsion does not adhere to the tire of a construction working car.

Filed: 1988-02-02
Abstract: PURPOSE:To enable the execution of doping at a room temperature, by a method wherein a flat plate containing a compound of a doping impurity and a semiconductor substrate are disposed in parallel substantially and a reduced-pressure plasma is generated in a gas atmosphere of an inactive gas. CONSTITUTION:A flat plate 6 containing AlAsO4, SiP2O7 or BN or the like is disposed substantially parallel to an Si substrate 7. A tube 5 is filled up with an inactive gas or a gas atmosphere containing this gas and a minute quantity of oxygen. The atmosphere inside the tube 5 is set to be a reducedpressure atmosphere 9 by a mechanical pump. A temperature inside the tube 5 is set at 400 deg.C by an outside heater 10. A high-frequency power and a DC bias voltage are impressed on plasma electrodes 12 and 13. Since a mean free path of a molecule is about 5mum, the quantity of an impurity atom arriving at the bottom surface of a trench groove having a depth of 5mum or below is equal to that on the surface thereof, and consequently a doping layer 3 is formed in the groove uniformly. By this method, the execution of doping at a room temperature is enabled.
