Title: Thermal printing head
Inventor: MATSUO YASUZO
IPC: H01L49/00
Filed: 1984-10-29
Abstract: PURPOSE:To contrive enhancement of film hardness and thermal shock resistance, by forming a protective film layer from a mixture of a silicon nitride compound and a tantalum pentoxide compound. CONSTITUTION:A substrate 2 provided with a heating resistor 3 and conductor electrodes 5, 6 is placed in an argon atmosphere, and sputtering is conducted using a target consisting of a mixed sintered body of Si3N4 and Ta2O5 in an appropriate mixing ratio, thereby providing the protective film layer 7. By mixing Si3N4 with Ta2O5, internal stress is alleviated, and a body superior than a body consisting solely of Ta2O5 in film hardness and having excellent thermal shock resistance can be obtained. Accordingly, the hardness of the protective film is markedly enhanced, flaws in the moving direction or the like are prevented from being generated, and useful life of a thermal printing head 1 is prolonged. In addition, since the hardness of the protective film is increased, the film thickness can be reduced as much, and heat response characteristic is enhanced.

Filed: 1984-10-31
Abstract: PURPOSE:To obtain stable and proper identification level by using a DC voltage being an output of a peak value detecting circuit branched to an output of an equalizer equalizing an output waveform of an avalanche photo diode for an identification circuit. CONSTITUTION:An optical signal inputted to the avalanche photo diode APD1 is converted into an electric signal, amplified by a variable gain amplifier 2, inputted to an equalizer 4, where the signal is subject to waveform equalization. The peak value detection circuit 6 is branched to the output of the equalizer 4, a DC voltage being an output of the circuit 6 controls the gain of the amplifier 2 via an AGC control circuit 3 to change the bias voltage of the APD1 thereby controlling the amplification factor of the APD1 and making the input amplitude of the identification circuit 5 nearly constant. The output of the circuit 6 is inputted to a differential amplifier 11 to which a voltage adjusted by a variable resistor 13 is fed at the same time. Since the output voltage of the amplifier 11 is constant and stable, the stable reproducing waveform is obtained from the circuit 5 by using the output of the amplifier 11 as an identification level of the circuit 5.

Filed: 1989-09-04
Abstract: PURPOSE:To eliminate noise as the synthesis error of a pseudo echo by providing an adaptive echo canceller referencing a reference noise signal and extracting a voice signal from a received privacy call signal with a prescribed level. CONSTITUTION:A privacy call signal is led to a reception side input terminal 111 via a transmission line 110. An adaptive echo canceller 112 synthesizes a reference signal outputted from a reference noise generating circuit 113 generating substantially the same noise as that from a transmission noise generating circuit 102 with a pseudo echo by passing through the reference signal to a transversal filter. An input signal to the adaptive echo canceller 112 is referenced and the gain of a variable gain amplifier circuit 115 is controlled to mute the noise based on the result of estimate of a cancellation quantity estimating circuit 114 estimating the cancelling quantity of echo and a tap coefficient of the adaptive echo canceller 112 is initialized in the mute range. Thus, the noise due to a synthesis error of the pseudo echo due to the adaptive echo canceller is muted against the fluctuation of a large transmission loss in the transmission line including the space.

Title: Exposing method for optical information recording medium and its master disk
Inventor: SHIMIZU AKIHIKO
IPC: G11B7/24085
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely reproduce a phase pit indicating preformat information by the push-pull method, etc., without being interfered with adjacent phase pits even if the phase pit is present in the same position for an adjacent track for recording the information. SOLUTION: The center of the track of a group G and the center of the phase pit P are concentric, the groove width of the group G is the same as that of the phase pit P, the groove depth of the groove G is the same as that of the phase pit P, the inclinations θ1, θ2 of both side edge parts in the radial direction orthogonal with the track of the phase pit P are different from each other. Consequently, by merely making the inclinations θ1, θ2 of both side edge parts in the radial direction of the phase pit P different from each other to form a groove-section shape unsymmetrical with respect to the center of the track, the phase pit P does not link with the group G adjacent thereto, and even when the phase pit P is adjacent in the radial direction, the phase pit P is stably reproduced without being interfered therewith.
