Title: Protective circuit for printer
Inventor: MASUKO KAZUYUKI
IPC: B41J2/375
Filed: 1987-03-09
Abstract: PURPOSE:To protect an actuator-controlling circuit from an abnormal current, by a system wherein an output voltage from an integrating circuit corresponding to the duration of an output signal obtained by ORing is compared with a voltage set corresponding to a reference time, and an abnormal condition is discriminated based on an output from a comparing circuit before a control signal is outputted for such a long time as to deteriorate or damage an actuator or a controlling circuit. CONSTITUTION:When a control signal SOL for a traction solenoid 4 is brought to a low level, an output signal from a point (a) of an OR circuit 21 is brought to a low level. When an output waveform from the point (a) is outputted through inversion by a buffer 22 and a resistor R1, a capacitor C is charged from an initial state to a saturated state. Therefore, waveforms of inputs to a comparator 23 are such that the input level at a point (b) is lower than that at a point (c) in an initial period, but the relation is inverted after the lapse of a reference time T. At this point t1, an output from a point (d) of the comparator 23 is changed to a high level, and an output from a point (e) of a one-shot multivibrator 24 is maintained at a low level for the period from the time t1 to the time t2. As a result, resetting is performed.

Filed: 1991-03-18
Abstract: PURPOSE:To make it possible to perform measurement in a dry mode by forming an ionic macromolecular film on a supporting body, and measuring the potential of the film. CONSTITUTION:An ionic macromolecular film 12 is formed on a supporting body 13. Time potential of the film is measured with a surface potential meter comprising a fixed electrode 10, a movable electrode 11 and a meter 15. When odor material is brought into contact with the film 12 through an odor guiding pipe 9a at this time, the odor material is made to act and bonded with ion pairs. The electric charge of the ion pairs on the surface disappears, and only the ionic macromolecules remain The material acts so that the surface potential is changed. The concentration of the odor material is measured based on the change. Therefore, water is not required, and the measurement can be performed in a dry mode.

Abstract: PURPOSE:To uniform control the distribution of a processing speed inside a sample-processed plane with good reproducibility, by getting an electric field overlapped by a correcting magnetic field in correspondence with positions where a distribution of a speed of processing a sample by an ionized gas is uneven. CONSTITUTION:In case that evenness is deteriorated, a distribution of an etching speed fluctuates in a concentric circle-shaped form with the rotational axis of a rotational magnetic field element 6 serving as a center.
