Title: Supply system of cleaning liquid
Inventor: KUNO MASASHI
IPC: G03G21/10
Filed: 1981-05-11
Abstract: PURPOSE:To prevent the splash of the cleaning liquid as well the soil of an image due to the incomplete cleaning, by setting a larger amount for supply of the cleaning liquid during the prescribed cleaning excepting the recording mode than the amount of supply during the copying mode. CONSTITUTION:A cleaning timer circuit CT contains transistors (TR) Q1-Q3, an inverter IC1, a diode D1, capacitors C1 and C2, and resistances r1-r7. The time constant is decided by the resistance r1 plus capacitors C1 and C2. In the cleaning mode, TR Q1 is off with TRs Q2 and Q3 turned off. At the same time, a relay RA2 is turned on to close a constant-open contact RA2-1. An AC power supply S is directly supplied to a cleaning pump motor PM, and the developer is supplied to perform the cleaning. When a timer circuit CR is timed up, the relay RA2 is turned off. Then the contact RA2-1 is opened, and the voltage of the motor PM is lowered by a high-power resistance R. Thus the number of revolutions of the motor PM is reduced to decrease the supply amount of the developer.

In the case where (r) is 0 or the even number when the value of (q) or the oddness and evenness are different from the case, (r+1) is made into the value of x1. When (r) is the odd number, (r-1) is made into the value of x1. The remainder, after m2 is divided by p2, is made into the value of x2, and the information of the lattice point of the coordinates (m1, m2) of distributed to the processor of the number (x1, x2). Consequently, the odd points and even points of the lattice points are mapped in the same number to respective processors. Thus, the operation efficiency of the processor can be improved.

IPC: H03K4/50
Filed: 1985-04-02
Abstract: PURPOSE:To increase the timewise dynamic range by connecting two reset switch elements in parallel with a capacitor of a feedback circuit in a sawtooth wave generating circuit including an integration device so as to decrease the dependency of the scanning time of an output voltage of an integration circuit at blanking. CONSTITUTION:Two reset switch elements TR1, SW1 are connected in parallel with a capacitor C1 of a feedback circuit. Then only a transistor (TR) 1 is turned on at a period t1 where a large discharge current of the capacitor C1 exists, and the elements SW1 is also turned on when the discharge current is smaller than the permissible contact current of the element SW1. Thus, a voltage across the capacitor C1 is dropped rapidly up to a level of 0.1-0.01V so that the delayed appearance of a picture in a conventional circuit is avoided as the scanning time gets longer, thereby reducing the waiting time of the picture appearance.

Title: Abnormality detection of multiple-edged cutting tool
Inventor: NOBUHARA MASAKI
IPC: B23Q17/09
Filed: 1985-04-05
Abstract: PURPOSE:To automatically detect abnormality of a multiple-edged cutting tool such as a hob by setting a certain threshold value to a self-correlation factor of intermittent time cycles obtained from vibration at an appropriate position on a machine with the multiple-edged cutting tool during cutting. CONSTITUTION:From changes in cutting force of a multiple-edged cutting tool such as a hob, a self-correlation factor for the tool is obtained. Abnormality in the cutting tool such as edge breakage is detected from changes in the self- correlation factor. When periodic nature is evident in an irregular variance x(t) regarding time on a chart of irregular variance, a group of curves, if its time axis is shifted by its time cycle or by integral multiple of its time cycle, should be closely similar to the first group of curves. Therefore, periodic components during variation can be screened by comparing similarity of curves between the first and later groups by obtaining correlation between x=x(t) and x=x(t+tau) shifted by a time lag tau. For example, since abnormal cutting has a smaller correlation factor than normal between the first group of curves and a group shifted by intermittent time cycle, abnormality in hobbing can be detected.
