Abstract: PURPOSE:To reproduce data as the change of the intensity of diffracted light and to record information with a high density by properly changing the ratio between the line width and the interval of a diffraction grating composing a diffraction grating cell and recording the first data. CONSTITUTION:The optical information recording medium is constituted by arranging the plural number of diffraction grating cells 2, 3, 4 composed of a minute diffraction grating on the surface of a planar substrate 1 through a reflection layer (not shown in the figure). In such a case, based on the first original data for preparing an optical information recording medium body, by properly changing the ratio of the line width to the grating interval of a diffraction grating composing the cell 2 and recording the first data, information is recorded with an extremely high density since the data are reproduced by means of the change of the intensity of diffracted light.

Title: Pattern memory
Inventor: SUWAI REN
IPC: B41J2/355
Filed: 1982-11-27
Abstract: PURPOSE:To eliminate a buffer memory for temporary storage of pattern information by dividing a pattern memory into a plurality of memory areas into which a reorganized character pattern information for recording is written separately.

Title: Detection method for microcomputer runaway
Inventor: TANAGAWA KOJI
IPC: G06F11/30
Filed: 1984-10-04
Abstract: PURPOSE:To detect the runaway of a program in a real time by applying a D/A conversion to the contents of a program counter and monitoring the analog voltage. CONSTITUTION:An instruction is usually executed while the contents of a program counter 2 are increased successively. Thus the 2-bit digital digital values are supplied to the input of a D/A converter 4 in the order of 00 01 10 11-, and the output of the converter 4 is changed in the expected value. While the contents of the counter 2 are rewritten to the unexpected value when a microcomputer 1 has a runaway. Therefore the analog voltage obtained by the converter 4 through a D/A conversion is also set at an unexpected level at a time point when said runaway is produced. Thus a program runaway can be detected in real time by comparing the output of the converter 4 with an existing normal voltage waveform.

Title: Television receiver
Inventor: IGA HIROYUKI
IPC: H04N5/21
Filed: 1993-08-23
Abstract: PURPOSE:To improve the synchronous regeneration function in an on-vehicle TV or a portable TV. CONSTITUTION:A band of a video signal is limited to a Nyquist band or below (e.g. 1MHz) by an LPF 2 and the result is given to a ghost elimination circuit 8. A timing generating section 4 generates a timing signal based on a video signal pulse and the signal is given to a waveform memory 10 and a video signal of a part of a vertical blanking period for each field is stored in the waveform memory 10. A tap coefficient arithmetic operation is made based on a signal waveform stored in the waveform memory 10 and a tap coefficient is corrected for each field. Thus, a TF 13 generates a ghost cancel signal corresponding to a fluctuation ghost. Since the band of the video signal is limited by the LPF 2, the configuration of the ghost elimination circuit 8 is simplified. A synchronizing signal generating circuit 17 recovers the synchronizing signal from the video signal from which ghost is eliminated.
