Title: Optical recording medium and manufacture thereof
Inventor: TOMINAGA JUNJI
IPC: G11B7/24047
Filed: 1991-04-23
Abstract: PURPOSE:To obtain a recording medium regeneration meeting CD specifications and having high light-resistance by containing an inorganic compound, which is decomposed by heating and prevents a gas, in a recording thin-film. CONSTITUTION:An optical recording medium 1 has a recording thin-film 3, a derivative thin-film 4 and a reflective thin-film 5 on the surface of a substrate 2, and a protective film 6 is formed onto the reflective thin-film 5. When a recording laser is applied from the rear of the substrate 2 on recording and the recording thin-film is heated, a gas discharged from the recording thin-film 3. An air gap 31 is formed in the recording thin-film 3 by the gas generated. Since the substrate 2 near the recording thin-film 3 is heated and softened, a recessed section 21 is formed on an interface with the recording thin-film 3 by the pressure of the gas generated. Optical conditions such as the optical constant, optical length, etc., of a recording laser-beam applying section are changed by shaping these air gap 21 and recessed section 21, and reflectivity is lowered. The optical recording medium can be used as a worm type optical recording medium by the change of light reflectivity generated in this manner.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of overcurrent beforehand, by avoiding the state of the over-modulation of the switching signal wave even when system service interruption occurs during the operation of a converter. SOLUTION: This device has a bidirectional function of the inverter operation, which performs the AC conversion of the DC power from a DC power supply during the daytime and supplies the power to a load 6 and the system, and the converter operation which performs the DC conversion of the AC power from a system power supply 5 at night.

Title: Manufacture of liquid crystal display device
Inventor: TSUTSUI SEIJI
IPC: G02F1/1339
Filed: 1987-05-18
Abstract: PURPOSE:To prevent an air bubble from being produced even when a display device enters a low-temperature state by bringing one substrate where spacer particles are adhered into contact on only the external surface in a specific area and thus controlling the area where spacer particles are adhered. CONSTITUTION:One substrate 1 has a transparent electrode 3 and an orienting film 4 provided on the internal surface of a glass substrate 2. Then the substrate 1 is supported on a conductive stage 10 and the spacer particles 7 are scattered over the orienting film 4 from an injection port 11. In this case, the particles 7 contacts only the external surface of the electrostatically charged substrate 1 corresponding to the specific area where the particles 7 are adhered, e.g. is contacted by pressing and adhered on the surface of a stage 10 without contacting other areas except the specific area. Consequently, the surface potential drops only in the specific area. Further, the particles 7 are also insulators, so they are charged positively or negatively when they are injected 11. Further, there is a difference in electrostatic attracting force or repellent force generated between the particles 7, and the specific area and other areas of the substrate 1, so a difference in the distribution of adhesion density of the particles 7 is generated between the specific area and other areas. At this time, the stage 10 is grounded and the repellency becomes weaker in the specific area, so that the particles 7 become easier to adhere.
