Title: Pattern recognizing system
Inventor: MAEDA KENICHI
IPC: G06V10/70
Filed: 1983-09-07
Abstract: PURPOSE:To recognize effectively an input pattern by showing this pattern in the form of a partial N-dimensional space to obtain the similarity to a dictionary shown in the form of a partial M-dimensional space based on an angle formed by both spaces, and therefore allowing the deformation over a wide range. CONSTITUTION:An input pattern is shown by a vector A of this pattern and a partial space D including the deformation of the vector A, and an angle theta formed by both partial spaces C and D is used as a criterion for similarity. The angle theta is set at the minimum angle among those formed by the vectors of each partial space. With use of this angle theta, the input pattern is shown in the form of a partial N-dimensional space whose deformation is presumed. Thus it is possible to recognize the input pattern with a wide range of deformations covered together with a dictionary shown in the form of a partial M-dimensional space.

Title: Optical disk device
Inventor: INOUE TAKASHI
IPC: G11B7/09
Filed: 1995-06-30
Abstract: PURPOSE: To surely detect a track jump even when a fluctuation component of a low frequency exists in a tracking error signal. CONSTITUTION: The mean value TEM of the tracking error signal TER is obtained by a low-pass filter 7. As track jump detection levels, the potential adding a DC voltage of a voltage source 8 in the positive direction and the potential subtracting the DC voltage of the voltage source 10 in the negative direction for the mean value are used. Since these detection levels follow up the fluctuation in the tracking error signal occurring even when the tracking is applied normally, the track jump detection level viewed from the tracking error signal is held to a fixed level always, and the track jump is detected surely.

Filed: 1995-06-30
Abstract: PURPOSE: To improve the injection speed by detecting inner pressure increase in a tubing system with a pressure sensor, reversely rotating a pump and returning the inner pressure in the tubing system to the atmosphere pressure at the time when a nozzle is lowered from above a sample vessel. CONSTITUTION: When a nozzle 14 is lowered as a very small amount of air is discharged from the edge of the nozzle 14, inner pressure in a tubing system increases from a pump 18 to the nozzle 14 through an air tube 24 at the time point when the edge of the nozzle reaches a liquid surface of a sample 10. When a pressure sensor 26 detects the pressure in the tubing system and detection pressure exceeds a threshold value, it is detected that it reaches the liquid surface. Just after liquid surface detection, lowering of the nozzle 14 is stopped, and the edge of the nozzle is advanced from the liquid surface to specified depth. A control part receives an output signal of the sensor 26, the pump 18 is sucked on the basis of inner pressure change in the tubing system, and the inner pressure in the tubing system is enforcedly returned to the atmospheric pressure. Thereby nozzle positioning for a suction start position and making a reference state for sucking the sample of tubing system inner pressure can be performed speedily.

Title: Deflected position control method for deflection control ink jet recording
Inventor: EZAKI TAKASHI
IPC: B41J2/12
Filed: 1979-12-22
Abstract: PURPOSE:To realize an application even for such nozzle plate to which the ink jet mounts are arrayed in an inaccurate way, by securing a control for the level of the deflecting voltage as well as the level difference of the charge voltage with every ink jet mouth. CONSTITUTION:The level difference among the dots of the charge voltage that changes the ink particles is reduced to decrease the space between dots. Thus the record enable range of a jet mouth, i.e., the pitch is narrowed as shown by the figure (c). While the pitch is increased as shown by the figure (d) when the above- mentioned level difference is increased. When the deflecting voltage is increased, the dot group that performs recording with an ink jet mouth deflects to the right. And the dot group shifts to the left with a reduction of the deflecting voltage. As a result, the pitch width and the left-right position shift can be controlled by giving a control to the charge voltage and the deflecting voltage with every ink jet mounth. Thus the disturbance and uneven density can be eliminated for a recorded picture although the space is not equal among all ink jet mouths.
