Abstract: PROBLEM TO BE SOLVED: To constitute an optical element and an information recording and reproducing apparatus in which information can be transferred at high speed and in which a recording operation can be performed with a higher density than an optical disk apparatus in conventional cases by a method wherein a pinhole which has a sufficient light transmittance is formed in a slider. SOLUTION: The end face of an optical waveguide or an optical fiber 4 is cut obliquely. A metal film 5 is formed on the end face. A pinhole 6 is formed in the metal film 5. The angle which is formed by the optical axis of the optical waveguide or the optical fiber 4 with the end face is set at an angle at which a surface plasmon is excitated in the metal film. Thereby, the transmitted light rate of the pinhole 6 can be increased, and it is possible to constitute an information recording and reproducing apparatus in which a recording operation can be performed with high density and whose data transfer rate is fast.

Title: Data communication system and method
Inventor: OTSUKA SHUJI
IPC: B41J29/00
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a printer control circuit capable of conducting two-way communications without increasing the number of I/O ports. SOLUTION: The data communication system comprises three circuit modules M1, M2, M3 connected in a ring state, and transmits a packet in a unilateral direction between the modules. For example, the module M1 transmits and receives data to and from a host computer, the module M2 processes the image, and the module M3 controls a printer mechanism. Since the packet can be transmitted only in the unilateral direction, a data transmission speed can be accelerated, and pseudo-two-way communications can be conducted. Since the packet can be transmitted only in the unilateral direction, the number of the I/O ports can be reduced. Further, since the packet is communicated between the modules, desired data can be effectively transmitted to the desired module.

Abstract: PURPOSE:To attain excellent picture reproduction by changing a frequency characteristic of an LPF passing a reproduction signal in response to an output resulting from applying extraction and peak-detection to a signal representing a sample frequency included in the reproduction signal so as to obtain a transfer characteristic close to a symmetrical roll-off characteristic. CONSTITUTION:A video signal reproduced from a magnetic medium 1 is given to an SV reproduction process circuit 4 via a reproduction amplifier 3, in which processing such as FM demodulation and de-emphasis is executed and the resulting signal is fed to a picture memory via an A/D converter 8. In this case, an output signal of the circuit $4 passes through an LPF 5 and a gate circuit 6 extracts a sine wave of a frequency equal to a sampling frequency fs added to the picture signal. The frequency characteristic of the LPF 5 is changed in response to a peak level of the sine wave by a peak detection circuit 7 to set the characteristic within a range of -6+ or -3db. Thus, the transfer characteristic close to the symmetrical roll-off characteristic is obtained as a whole and excellent picture reproduction is attained.
