Title: Optical recording method and optical recording medium using that
Inventor: TOMINAGA JUNJI
IPC: G11B7/24035
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To enable high-density recording and reproducing of information by irradiating the surface of a recording layer comprising a material in an amorphous state at a temp. lower than the crystallization temp. with light to produce only crystal cores to record information and reading the difference of optical characteristics between the crystal core and the surrounding amorphous part to reproduce the information. SOLUTION: An optical recording medium is produced by forming a SiN dielectric layer 3 on a glass substrate 1 having good flatness, and forming a recording layer 4 comprising a GeSbTe alloy, and further forming a SiN dielectric layer 5 thereon. A thin metal layer 2 may be formed between the substrate 1 and the dielectric layer 3 so as to conduct heat produced when the recording layer 4 is fused through the dielectric layer 3 to the metal layer 2 to improve the cooling effect. The recording medium has an amorphous recording layer 4 on a transparent or opaque substrate 1. It is preferable that by irradiating the recording layer 4 with light, a crystal core having 1 to 50 nm radius on the surface is produced and that the thickness d of the recording layer 4 and the radius r of the crystal core satisfy the relation of d>2r.

Title: Control system for nonvolatile memory
Inventor: KUROSAWA KAZUYUKI
IPC: G11C17/00
Filed: 1990-10-01
Abstract: PURPOSE:To perform a due processing operation with use of the highly reliable data by checking the coincidence between the data written in the 1st and 2nd specific addresses through the comparison of them to decide whether the data are destroyed or not and therefore inhibiting the use of the destroyed data to carry on the processing to minimize the damage. CONSTITUTION:In an execution mode of a navigation mode, the same data are written in two specific addresses before and after the data on an EEPROM 25 are updated. These written data are compared with each other and the coincidence of them is checked at initialization. Thus it is possible to decide whether a power supply is turned off and the data are destroyed or not when the data on the EEPROM 25 are updated. As a result, the destroyed data are never used when a due processing operation is carried on. Then the processing can be carried out with use of the highly reliable data.

Title: Head drive circuit
Inventor: NOGUCHI MASATOSHI
IPC: B41J2/355
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To eliminate a reverse current element diode by providing a power supply setting a specific amount of an energy to be imported to one group, while another group is performing a printing operation. SOLUTION: When the number of drivings of a heat-generating printing element is small and the inflow amount of an electric current into an antiphase is increased, a second transistor draws a larger amount of electric current than usual to bring an output voltage e0 close to a reference voltage (e). When the inflow amount of the electric current into the antiphase is decreased, a first transistor T1 discharges a large amount of electric current to bring the output voltage e0 close to the reference voltage (e).  Further, the energy to be given to the heat-generating printing element not engaged with printing can be limited to a constant range or a specified range regardless of an increase or decrease in the number of drivings by a sneak current or an antiphase current, through the retaining of a power supply lead belonging to another group not in a driving state at a specific potential level. Thus a reverse current element diode is not required.
