Title: Recording device
Inventor: TANIOKA HIROSHI
IPC: B41J2/33
Filed: 1988-01-14
Abstract: PURPOSE:To prevent the breakdown of an electrode drive circuit by an overcurrent by forming ink through application of a specified energy to liquid ink and controlling an applied energy value by using an energy application drive means so that said value is limited to a level below a specified value. CONSTITUTION:A patterned voltage, e.g., +15V is applied to transported ink 2 on an energy application position where the ink 2 comes into contact with a recording head 5, in accordance with a pixel signal from a recording head 5 controlled by a control system. As a result, an electric current runs to an ink transport roller 1 from an electrode element 5d through the ink 2, and the cross-linking structure of the ink 2 changes by electrochemical reaction in the ink. Subsequently, the ink 2 selectively becomes viscous to form an ink image 2a. Further, if a head electrode comes into contact with the ink transport roller 1 due to defective coating, etc., during energization, an overcurrent does not run.

Abstract: PURPOSE:To expand the control range of a light receiving time for the alteration of light quantity and to prevent the accumulation of charges caused by a dark current by setting the optimum clock frequencies for light receiving, reading and idling periods. CONSTITUTION:When a central processing unit 8 issues a detection starting command, a pattern detection command circuit 5 makes a switching signal generation circuit 41 in an initial state, namely in a light receiving period state. Thus, a clock signal generation circuit 3 outputs the clock signal of a frequency corresponding to the light quantity of image-formation. Next, when the switching signal generation circuit 41 becomes in a reading period state the set value of a reading period frequency setting unit 44 is transmitted to the clock signal generation circuit 3 and the clock signal of the maximum response frequency is outputted from the clock signal generation circuit 3 to a sample/hold circuit 6 and a digital conversion circuit 7. And when the circuit 41 becomes in the idling state, the clock signal of the maximum response frequency of a photoelectric conversion circuit 2 is outputted.

Title: Electromagnetic flowmeter and converter
Inventor: HONDOU TSUTOMU
IPC: G01D1/02
Filed: 1982-01-18
Abstract: PURPOSE:To obtain an electromagnetic flowmeter and converter which has a signal processing system improved so that the influence of abrupt variation in interelectrode DC potential such as a DC noise voltage based upon an electrochemical factor contained in a received signal from an electromagnetic flowmeter and transmitter is removed. CONSTITUTION:The output of a transmitter 1 is passed through a high-input impedance amplifier 6 and then rectified synchronously by the synchronous rectifying circuit consisting of changeover switches SW2-1 and SW2-2 controlled by a signal (j) from a timing circuit 5 corresponding to energizing polarity and an amplifier 7. Its output is inputted to an averaging circuit 8 normally through an SW3-2 to be averaged in time series, thereby outputting an output signal (d) proportional to the velocity of flow. The input signal to the averaging circuit 8 has states 1, 2, and 3 as shown in a tableI. Thus, the averaging circuit 8 inputs a signal d-f or d+e instead of an abrupt variation signal, so variation of an averaging output signal (d) is suppressed.
