Filed: 1990-11-14
Abstract: PURPOSE:To improve the detecting precision in a simple constitution by deciding the error value between a station and a set proper state of a mobile vehicle based on the information read out of plural basic members by an image pickup means. CONSTITUTION:A manipulator 1 moves automatically an image sensor Sa to two reading set positions set opposite to two reference members 3 respectively based on a command of a controller 12. The entire members 3 are photographed at the 1st set position and this image pickup signal is inputted to an image processing part 11. Then the error value is obtained between each original point (center of screen) of the X and Y coordinates and the centroid of each mark 1 (member 3) on a screen. Then the sensor Sa is moved to the 2nd set position and the error value is obtained in the same way between the center of screen and the centroid of each mark 2. Thus the error value between a mobile vehicle A and its proper state set to a station is obtained based on those two obtained error values.

IPC: H03F3/345
Filed: 1993-11-17
Abstract: PURPOSE:To stably realize complete full swing by cutting off power output MOSFET on the opposite side of power output MOSFET on a driven-side. CONSTITUTION:When the voltage of an input terminal 1 to about power voltage Vdd and PMOSFET Q10 is cut off, NMOSFET Q20 of a negative side detection circuit 7 is also cut off. Thus, the drain voltage of PMOSFET Q21 is impressed on the gate voltage of NMOSFET Q21 of a negative side correction circuit 8 and NMOSFET Q22 is turned on. Thus, the gate of power output NMOSFET Q2 is grounded and it is completely cut off. When inputted voltage drops to about ground voltage, the gate of PMOSFET Q8 comes to a floating state (or power potential). At that time, PMOSFET Q17 of a positive side detection circuit 5 is cut off, PMOSFET Q19 of a positive side correction circuit 6 is turned on and power output PMOSFET Q1 is cut off.

Filed: 1986-12-27
Abstract: PURPOSE:To quickly know an outline of the check data by showing the checking dates and the checking items in a matrix form without reading all check data on a recording medium where the check data are recorded when these check data are displayed. CONSTITUTION:A doctor puts a cursor coupled to the shift of a pointing device PD on a column 5-1 of glycosuria and clicks a button of the PD. Then the doctor performs the same operations on a column 5-2 to show the data, i.e., the blood sugar set between both columns 5-1 and 5-2. In this case, a VRAM of a computer (not shown here) senses two points of the cursor when the PD clicks and a CPU (not shown here) detects said two points of the cursor. Thus the recording address of the desired blood sugar value data recorded on an optical card (not shown here) is detected by the directory of the optical card stored already. Then a reading device for optical card reads out the check data on said recording address and shows them in a graph.

Title: Driving method for ink jet head
Inventor: FUJII MASAHIRO
IPC: B41J2/055
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To jet an ink droplet appropriately at the time of preliminary jet driving in such type of ink jet head as an ink droplet is jetted by varying the volume of an ink chamber communicating with a nozzle. SOLUTION: At the time of preliminary jet driving of an ink jet head, a drive voltage pulse V is applied between a common electrode 17 (diaphragm) and an individual electrode 31 such that the ink droplet is jetted by push hit system. At the time of print jet driving for printing a character of the like on a recording paper, a drive voltage pulse V is applied between the electrodes such that the ink droplet is jetted by pull hit system. Since a push hit system for jetting the ink droplet regardless of the characteristics of ink, e.g. viscosity, is employed for preliminary jet driving, the ink droplet can be jetted under an appropriate state at all times. Consequently, the nozzle can be recovered surely. At the time of printing a character or the like, the ink droplet can be jetted stably at high speed by pull hit system.
