Title: Method and device for controlling arc length in nonconsumable electrode type automatic welding
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/12
Filed: 1986-07-17
Abstract: PURPOSE:To enable a stabilized arc length control even if the response of a control system is remarkably made higher by offsetting the ripple part of an arc voltage by overlapping a reverse polarity or homopolarity on a feeding wire and the body to be welded or on the voltage between electrodes. CONSTITUTION:The base metal 5 to be welded and the voltage Va of a feeding wire 7 are detected through the voltage detection circuit composed of a differential amplifier 21 and low pass filter 22. The voltage Va is attenuated in the prescribed Va/N times by an attenuator 23 and fed to a computing clement 24. The element 24 substracts the voltage Va/N from the arc voltage which is led through a low pass filter 8 and sends out to a comparator 13. If the attenuation magnification 1/N thereof is made proper, the substraction part thereof can be approximated to the corresponding part of the ripple of the arc voltage having passed through the low pass filter 8. As a result, the arc voltage compared with the set arc voltage becomes the voltage that the ripple part is sufficiently reduced, so the stability of the control system can be secured even if the gain of the amplifier circuit 15 is taken higher.

Filed: 1983-09-09
Abstract: PURPOSE:To provide a combustion control device in which a fine flame current can positively be sensed by a method wherein a flame current is converted into a desired signal through a current amplifying means. CONSTITUTION:A current amplifying means 17 for amplifying by several times a flame current sensed by a flame rod 1 is composed of a calculation amplifier 18, resistors 19, 20 and 21 and a capacitor 22, and a reference input potential for the calculation amplifier has the same potential as a ground potential of a combustion burner 12 and the circuit through the resistor 23.

In particular, in case that a rate of amplification must be increased when a fine current is sensed, the off-set voltage is kept constant without any relation with a rate of amplification.

When the linear speed of the disc becomes higher, the pulse width of the EFM signal P1 is reduced; and when it is shorter than a minimum bit length, a NAND gate 6 gives a DOWN pulse shown by P7 to the flip flop 8, and this pulse is outputted as a reduction signal Q to reduce the rotation number.

Title: Timer
Inventor: TANABE AKITO
IPC: H03K17/28
Filed: 1979-12-22
Abstract: PURPOSE: To perform the time-limiting and adjustment of sound volume with a small-sized constitution by shifting and selecting a timer counter and a sound volume counter and making an indicating device, etc. operate correspondingly.  
     CONSTITUTION: When a shifting switch 1 is connected to the side of a contact point 1b, AND gates 2 and 3 are opened by a high-level output, while the counter 4 for a timer is set to be in the state of nonoperation and a shifting circuit 12 selects the sound volume counter 9. And, corresponding to the operation of switches 7 and 8, the counter conducts up or down counting, thereby sound volume controlling voltage corresponding to setting is generated, while the output of the counter 9 is decoded by a decoder 16 and the prescribed transistors Q 1 WQ 7  of the indicating circuit 18 are made conductive, thus the sound volume is indicated by LEDD 1 WD 7 . Meanwhile, when the time-limiting mode is set through the intermediary of the switch 1, the counter 4 which is capable of being set initially is counted down by a pulse outputted by the counter 5 at every 10 minutes through the intermediary of the switches 7 and 8, the remaining time is indicated by LEDD 1 WD 7 . Since a part used for two purposes is much, the time-limiting and the adjustment of the sound volume can be performed selectively by a simple and small-sized constitution.

IPC: H04N1/405
Filed: 1993-06-14
Abstract: PURPOSE: To keep an output of a minimum spot size, while keeping gray density. CONSTITUTION: In order to decide a signal Bn ,L after threshold level processing, a tentative output signal B'n ,L is fed to a counter 40, which counts up to a number N from 1, when it is enabled. When the count reaches N, the counter 40 generates an enable signal TRANEN. to an output decision section 42. The output decision section 42 gives a tentative output signal B'n ,L to an output image storage device 16, when it is enabled. When the transition from a 1st state to a 2nd state is detected while the output decision section 42 is enabled, the output decision section 42 generates a counter start signal CSTART to allow the counter 40 to count from 1 to N, thereby making the TRANEN of the output decision section disable.  An output of the output decision section is connected to an output image storage device 16 for transfer of the output to a print buffer along a signal line 18 in an event occurrence.
