IPC: G11B7/253
Filed: 1993-03-09
Abstract: PURPOSE:To accelerate decoloration by a photochromic reaction and to improve recording sensitivity by using a material having a heat radiation effect as a material of a transparent substrate holding a recording layer in-between and a substrate which is the ground surface for a recording film. CONSTITUTION:This recording medium 1 has a structure formed with a dyestuff film 3 on the substrate 2 consisting of a material having the heat radiation effect. The heat (far IR ray) accumulated in the substrate by the photochromic reaction (optical isomerization reaction) by a laser beam and in addition the photothermal conversion in follow up thereto is released from the substrate consisting of the photothermal conversion material into the dyestuff LB film sticking to the upper part and, therefore, the J associate of the irradiated part is activated by this heat (far IR ray) and a decay reaction is accelerated. The recording sensitivity is further improved as compared with the conventional optical recording medium using the light alone.

Title: Printer and control method for correcting recording start position
Inventor: NAITO HIDEKI
IPC: B41J2/51
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a printer capable of preventing shift of a recording start position before or after the replacement of a ribbon cassette and of performing the high quality record by proving a control section that shifts the recording start position to a front side in the recording direction by a prescribed quantity to start the recording when the ribbon cassette is replaced. SOLUTION: A ribbon cassette is replaced to release the compression of damper rubbers 37, 45, consequently, a carriage 6 is taken back in the recording direction compared to a position at the completion of the recording. As a result, when the recording is started in this condition, the recording position is shifted. In order to correct the shift, detection is made as to whether the ribbon cassette is replaced after an ink ribbon is out. Upon the detection of the replacement, a control section 46 delays a starting time of energizing a recording head 7 and shifts the recording start position to a front side in the recording direction by 0.3mm from the recording end position when restarting the recording. Thereby, it is possible to prevent a shift of the recording position before or after the replacement of the ribbon cassette and to perform the high quality recording.

Abstract: PROBLEM TO BE SOLVED: To improve a noise exponent and a tertiary distortions, when a gain is low by detaching a variable gain amplifier whose gain of a device having a plurality of variable gain amplifiers is not more than 0dB from the device. SOLUTION: When a control circuit 3 sets the gain of the variable gain amplifier of a prescribed stage to be not more than 0dB via gain control signal lines 41-44, switching signals are sent to input/output change-over switches 21-28 provided before and after the stage through switch change-over signal lines 51-54. The variable gain amplifier of the stage is detached, and through lines 31-34 are connected. Thus, a noise index and tertiary distortions, which occur at the time of low gain amplification, can be improved by detaching the variable gain amplifier whose gain becomes not more than 0dB. Moreover, shielding effect between an input terminal 1 and an output terminal 2 when the gain is low, can be improved by perplacing the through lines 31-34 with buffer amplifiers.

Title: Noise removing device for slip ring
Inventor: KONAKA TOSHIO
IPC: B41J29/00
Filed: 1990-02-28
Abstract: PURPOSE:To prevent a printing head from being judged as abnormal by noise by a method wherein a slip ring is rotated when a control circuit has judged an abnormality and the slip ring is stopped while the abnormality or the normality of the object of inspection is judged by the control circuit based on a signal value taken out by a temperature sensor under the rotating condition of the slip ring within a predetermined period of time. CONSTITUTION:When the abnormality of temperature is detected in a printing head 30, a control circuit 45 judges the condition of a motor 32 and when the motor 32 is being stopped, the motor 32 is rotated by a motor driving circuit 49. At this moment, a timer 43 is operated and starts the count of a predetermined time. When the value of comparison from a comparating unit 37 shows the abnormality of temperature while the timer 43 is counting the predetermined period of time, the abnormality of temperature is not due to the noise of a slip ring and it is judged that the abnormality is due to the abnormality of the device itself. In this case, a signal, showing count-up, is sent from the timer 43 to the control circuit 45. The control circuit 45 responds to this input and stops the motor 32 through the motor driving circuit 49 and indicates the 'error' of the device in an indicating unit 48.

IPC: G01R13/32
Filed: 1981-03-31
Abstract: PURPOSE:To stabilize D.C. characteristics including offset voltage in a trigger amplifier by giving the output of the trigger amplifier to the input thereof as negative feedback by using a differential amplifier whose alternating-current transmission characteristics are suppressed. CONSTITUTION:A trigger amplifier TA is provided with a differential amplifier DA separately. Between the inversion input and the output of this amplifier DA, a capacitor C2 for alternating current negative feedback is inserted as a feedback circuit, and thereby the alternating-current transmission characteristics of the amplifier DA is suppressed and the amplifier DA passes only direct current. In addition, the output of the amplifier TA is impressed on the inversion input of the amplifier DA through the intermediary of a resistor R3, while the output of a voltage division circuit by a potentiometer RV1 is impressed thereon through the intermediary of a resistor R4, and the output of the amplifier DA is inputted in the amplifier TA via a resistor R5. The output of the amplifier TA is given to the input of the amplifier TA as negative feedback by this constitution, while a voltage for setting a trigger level is fixed in accordance with the adjustment by the potentiometer RV1. Thus, it becomes easy to maintain the input impedance of a trigger input terminal TRG.IN at a high value.
