Title: Lock detection circuit
Inventor: YAMAMOTO MASAYA
IPC: H03L7/18
Filed: 1985-12-19
Abstract: PURPOSE:To detect out of synchronism of input and output signals of a phase locked loop by allowing a gate circuit to OR output data of two shift registers after parallel conversion when the input signal and the output signal are not synchronized. CONSTITUTION:When the input signal A and the output signal B are synchronized, a shift register 17 fetches the signal A as a data at the leading of the signal B and a shift register 18 fetches the signal B as a data at the trailing of the signal A. In repeating the operation over 4 periods after synchronization, all output terminals of the shift registers 17, 18 go to an H level. The levels are ORed by AND gates 19, 20 and go to an L level by a NAND gate 21 to form the lock state. When the signals A, B are out of synchronism next, since the level of the shift register 17 is at an L level in fetching the signal A, the level of corresponding 1-bit in output 4-bit goes to L. Thus, the output of the AND gate 19 goes to an L level, the output of the NAND gate 21 goes to H level, which is outputted till the next 4 periods.

Title: Scanning type probe microscope
Inventor: KAJIMURA HIROSHI
IPC: G01N19/08
Filed: 1990-10-26
Abstract: PURPOSE:To prevent collision of a probe with a sample even when encountering sharp irregularities of the sample by widening a distance between the probe and the sample irrelevant to a Z-wise servo control means when a detection value of a two-dimensional displacement of the probe exceeds a specified value in an atomic microscope or the like. CONSTITUTION:The surface of a sample 34 undergoes a two-dimensional scanning with a probe 14 mounted on a cantilever 12. A laser light from a laser 24 is reflected with a mirror 16 or the like of the lever 12 to be received with a photo detector 32 and a Z axis-wise displacement of the probe 14 is detected to control a supply current to a piezo-electric element of a piezo-electric actuator 36 of a Z-wise servo control means so that a displacement between the sample 34 and the probe 14 becomes constant in value to measure irregularities of the sample surface from the resulting current value. When DELTAX1 of a two-dimensional displacement value detection value of the probe in scanning exceeds a specified value, the probe 24 has a distance DELTAZ widened between the probe 24 and the sample 34 irrelevant to the Z-wise servo means. This control allows avoidance and prevention of collision of the probe with the sample even when encountering sharp irregularities of the sample.

Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus capable of performing a flashing operation by an optimized drive signal and capable of efficiently discharging unnecessary ink such as thickened ink or the like. SOLUTION: A piezoelectric vibrator 6 is contracted and extended by sending a drive signal COM from a printer controller 19 to the electric drive system of a recording head. Since the piezoelectric vibrator 6 displaces the surface of the vibration plate of a pressure chamber allowing ink to flow in the recording head, ink drops are ejected from nozzle orifices to print (record) an image or character on recording paper. When a flashing command is issued in a control part 194, a predetermined parameter is sent to a drive signal forming circuit 8 to form a first drive signal with a waveform capable of suppressing the lead-in of the meniscus of each nozzle orifice and a second drive signal with a waveform and a repeating cycle at a time of usual printing and these signals are successively sent to the electric drive system 44 to perform two-stage drive control.

Title: Cylinder cleaning device for printer
Inventor: HARA AKIRA
IPC: B41F35/06
Filed: 1988-11-14
Abstract: PURPOSE:To cope with a plurality of adjacent cylinders rotating reversibly by one cleaning device by pressing cleaning cloth to the different positions of the cylinders or the plurality of cylinders. CONSTITUTION:Cleaning cloth 63 is pressed to the surfaces of a blanket cylinder 2 and an impression cylinder 3 by pressure pads 66A, 66B to clean the surfaces. Since the rotation preventing mechanism of a cleaning cloth supply roll 61 is operated, even if the cylinder 3 is rotated in a direction (b), the cloth 63 is not pulled out from the roll 61. When the cylinder is further rotated so that a signal from a detector for detecting a rotating angle indicates that the pads 66A, 66B are opposed to gaps 24, 34, the mechanism of the roll 61 is released to become rotatable. Then, the cloth 63 is wound in a predetermined amount by driving means of a cloth winding roll 62. When the winding operation of the predetermined amount is finished, a control mechanism outputs a signal to recover the preventing mechanism of the roll 61 thereby to prevent the cloth from unsewing at the time of cleaning to continue cleaning.
