Filed: 1986-03-18
Abstract: PURPOSE:To prevent a thermal head from being caught by an edge of a paper, by determining a starting timing for an approaching action of the thermal head according to a printing speed, driving a pulse motor in an open loop based on the timing, and completing the approaching action in a predetermined period of time. CONSTITUTION:A spacing action of a thermal head 27 is started by a spacing motor, whereby the head 27 is moved in the direction of an arrow A. When the head reaches a position 29, it starts approaching a platen 25 by a pulse motor started with a timing determined by a processor, and it moves in the direction of an arrow B through the combination of the spacing action and the approaching action. The approaching action is completed at a position 30, and the head is brought into close contact with a paper 26 on the immediate upstream side of a printing-starting position. Since there is a blank between the printing-starting position on the paper 26 and an edge of the paper 26, the thermal head 30 will not be caught by the edge of the paper 26 if it is brought into close contact with the paper 26 on the immediate upstream side of the printing-starting position.

Title: Automation method in absolute calibration method for vibration pickup using interference fringe counting method
Inventor: NAKAMURA NAOTO
IPC: G01P21/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To perform an absolute calibration by automatic operation and to prevent an error from occurring, by calculating the detection vibration acceleration, judging whether a target is reached or not, calculating the update output voltage when the target is not reached, and calculating the sensitivity of a vibration pickup to be calibrated as an achieved vibration acceleration when the target is reached. SOLUTION: A vibration-generating device generates a vibration with a minimum output voltage being required. The detection vibration acceleration is calculated from the value of a ratio between the frequency of the interference fringes of irradiation light to be measured and a generated frequency, the wavelength of the irradiation light, and the vibration frequency. It is judged whether an operation result has reached a target vibration acceleration or not. Then, an update output voltage is calculated when the operation result has not reached the target vibration acceleration. A vibration is generated under the calculated update output voltage, and the detection output voltage of a vibration pickup to be calculated is read when the target has been reached, thus calculating the sensitivity of the vibration pickup to be calibrated along with the achieved vibration acceleration.  More specifically, the absolute calibration of the vibration pickup at the set frequency is performed.

Title: Automatic baking device
Inventor: KOYABU SEIJI
IPC: A47J37/00
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To produce bread though a bread dough expansion detecting means is abnormal by shifting the process to a baking processing after the lapse of a necessary time by neglecting the result of the detecting means during forming and fermenting processing in the case of judging the abnormality of the means detecting whether the expanded height of the bread dough reaches a necessary height or not. SOLUTION: At the time of starting a mixing processing, whether an output from a photodetective element is at a high level longer than a necessary time or not is judged first (S4 to S6). At the time of judging that the output of the photodetective element is at a low level, the processing shifts to a normal mode (S7 to S14) but at the time of judging that the output of the photodetective element is at a high level, an abnormality display lamp is lighted (S6) and the processing shifts to the flow of an abnormal mode (S30 to S35). At the time of starting forming and fermenting processing in the abnormal mode (S34), the lapse of the necessary time from a processing starting point of time is waited by completely neglecting the output of the photodetective element (S35) and the forming and fermenting processing is finished to be shifted to the baking processing (S15).

Filed: 1986-03-18
Abstract: PURPOSE:To prevent hang-up due to erroneous procedures and to reduce the procedure recovery time by providing plural procedure/non-procedure terminal equipments, plural low-speed lines, a high-sped trunk and a couple of statistic time-division multiplexers and controlling data transmission between low-speed lines during the period required from fault occurrence of the high-speed trunk to its recovery.

If a supervisory timer is over, the devices 1, 2 inhibit data transfer to and from terminal equipments 3, 4 having procedures and renounce the data resident in the data transfer to and from the devices 3, 4. When the fault is recovered, a link between he statistic time division multiplexers 1, 2 is established and the data transfer to and from the terminal equipments 3, 4 inhibiting the data transfer is applied. Thus, hang-up due to the procedure errors of the devices 3, 4 or the delay in the recovery of procedure is avoided.

Title: Manufacture of titanium alloy
Inventor: OKADA MINORU
IPC: C22F1/18
Filed: 1985-03-25
Abstract: PURPOSE:To minimize the amount of working in an alpha+beta region and to improve productivity by carrying out working successively in alpha+beta and beta regions at each prescribed reduction in area and then by carrying out ageing after water quenching in subjecting an alpha+beta type titanium alloy to strengthening heat treatment. CONSTITUTION:The alpha+beta type titanium alloy e.g. Ti-6Al-4V is worked at >=20% reduction in area at the temp. slightly lower than its beta-transus (usually 980-1,000 deg.C), at 800-950 deg.C in a high temp. region of the alpha+beta region. After that the alloy is hot-worked again at >=10% reduction in area, with or without cooling to the room temp., at 1,000-1,050 deg.C in a low temp. region of the beta-region, above the beta-transus; as to the above heating, it is desirable that the alloy is held with heating e.g. for <=30min in order to inhibit the growth of beta-recrystallized grains. After the hot working in the beta-region, the alloy is subjected to water quenching without delay and then to ageing treatment as usual.

Title: Integrated circuit for video head amplifier
Inventor: SHIBATA AKIRA
IPC: H03F3/187
Filed: 1979-05-18
Abstract: PURPOSE: To lessen fluctuations of a peaking frequency and gain remarkably by applying an independent DC bias to one cascode transistor by feeding an AC signal back to a cascode circuit via a resistance without damping.  
     CONSTITUTION: To put cascode-connected transistors Q 1  and Q 2  into stable operation, the output of emitter follower Q 4  is shifted in DC level by 2Vbc by using two diodes and then fed back to the base of Q 1  via resistance 10. As a result, the base potential of Q 1  is about Vbe regardless of a flowing current and the output DC potential of Q 4  is 3Vbe. The gain of the cascode amplifier composed of Q 1  and Q 2  is 40dB and varying variable resistor 7 from zero to the maximum varies a peaking value by about 6dB, but the gain of differential amplifiers Q 6  and Q 7  vary by about 1.5dB, which is not a problem. In addition, the base bias of Q 2  is independently applied, and consequently an AC signal generated at terminal 8 never appears at the base of Q 2 , so that a peaking frequency accompanying a damping adjustment will not change.

IPC: G03G15/04
Filed: 1990-03-14
Abstract: PURPOSE:To obtain resolution with required accuracy at a low cost by adopting the constitution such that the D/A converter is provided with a means employing a D/A converter with comparatively high accuracy D/A-converting several bits toward the most significant bit of a digital signal and with a means employing a D/A converter with comparatively low accuracy comprising an analog switch and a resistor D/A-converting remaining bits toward the least significant bit of the digital signal. CONSTITUTION:A D/A converter converts a digital signal into an analog signal by using a low cost 8-bit D/A converter 61 for the MSB side among 10 bits of laser output outputted from an optical write gate array. Moreover, the digital signal of the remaining 2 bits at the LSB side is converted into an analog signal by using two circuits of analog switches 62, 63 and resistors 63, 64 providing 1/2 and 1/4 of the minimum resolution of the D/A converter. The analog switches 62, 63 are turned on when an input signal LDPWnB is at an L level and a current is supplied via the resistors 64, 65. Since at least accuracy of 9 bits or over is warranted in spite of reduction in the accuracy of linearity, an LD output control signal with less quantization error is obtained.
