Title: Writing pressure control apparatus of plotter head
Inventor: TAKASAKI MAKOTO
IPC: B43L13/00
Filed: 1990-01-23
Abstract: PURPOSE:To always obtain good drawing quality without being affected by the irregularity or change of an apparatus with time by bringing a head raising and lowering movable part into contact with a pressure sensing element and controlling writing pressure on the basis of the relation between the output from the pressure sensing element and the supplied current of a coil driving the head raising and lowering movable part. CONSTITUTION:When a plotter apparatus is started, a microprocessor 22 moves a plotter head 1 to the position where the leading end of a pen 10 and a hole 15 are mutually opposed and supplies a current for pen down to the coil 33 of a raising and lowering driver 11. A moving frame 6 comes into contact with a pressure sensing element 14 at the C-point at the position slightly lower than a pen up/down region D. The supply quantity of a current to the coil 33 increases until the output from the pressure sensing element 14 is obtained and the current value of the coil 33 and the output of the pressure sensing element 14 are respectively sampled n-times from monitor circuits 21, 24 while the supply quantity of a current is changed to calculate a relational expression of a coil current and pressure. The proper writing pressure corresponding to a pen 10 is controlled on the basis of the calculated relational expression.

Title: Image drawing device
Inventor: OKUBO HIROSHI
IPC: G06T11/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of picture quality that is caused by the thinning processing. SOLUTION: An interpretation part 20 interprets the page description language, and an edge list generation part 21 produces the edge lists, being the intermediate data which are not converted yet into the raster data based on the interpretation result of the part 20. At the same time, the priority concerning the thinning processing is set in the order of a single line of the main scanning direction, the font, the edges, the graphics and the image data respectively based on the object information showing the types of images where the edge lists belong. A memory management part 22 manages the memory capacity that is needed for production of the edge lists. If the memory capacity is exhausted during the production of an edge list, a thinning mechanism part 23 is started by the part 22.  The part 23 thins the edge lists in the order of lower priority that is set among them and secures the memory capacity.

Title: Audible sound control system
Inventor: TSURUTA KAZUMOTO
IPC: H04M19/02
Filed: 1983-02-01
Abstract: PURPOSE:To simplify the processing of a central processing unit and to transmit an audible sound speedily by transmitting and receiving a control signal for identifying the kind of a trunk directly between a trunk and an audible sound sending circuit. CONSTITUTION:When the trunk 102 requires a dial tone, the central processing unit 101 connects the trunk 102 to the audible sound sending circuit 103 which sends out the dial tone. Consequently, the control signal sending circuit 106 in the trunk 102 sends out the control signal. The audible sound sending circuit 103 receives this control signal to discriminate the kind of the trunk 102 and controls the selecting operation of an audible sound selecting circuit 104. Consequently, an audible sound source, e.g. 107 is selected for output corresponding to the kind of the trunk 102 and supplied to the trunk 102 through a main channel network 100.

Title: Interruption control method
Inventor: MIYAGAWA TAKESHI
IPC: G06F9/46
Filed: 1988-01-25
Abstract: PURPOSE:To reduce the number of interruption generation signals by comparing the output of an ID register with address data on a common address bus at the timing of an interruption generation signal, and generating an interruption signal on a CPU when data coincide. CONSTITUTION:When the CPU 1 generates interruption on the CPU 13, the CPU 1 issues an I/O instruction to an I/O address which goes to the same value as that set at an ID register 14. As a result, I/O address data on a local address bus 3 passes an address bus buffer 5, and is outputted to the common address bus 19. Furthermore, the data on the bus 3 is decoded by a decoder 4, and a common interruption signal 9 becomes active. The data on the bus 19 to be inputted to a comparator 15 is compared with the data set on the register 14 at the active timing of the signal 9. When they coincide, a local address signal 10 becomes active, and the interruption on the CPU 13 can be generated.

Abstract: PURPOSE:To smoothly rotate a rotary member by allowing the exciting member of the rotary member rotated interlockingly with the opening or closing of the second unit to be wound on a rotary shaft in the circumferential direction for expansion or shrinkage and to apply the exciting force to the rotary member. CONSTITUTION:A sliding cam 3 is lifted upward by a sliding cam pedestal 1 to the second position, and a protective shutter 2 is moved by the cam 3 and a wire 5 to the position shown in the figure. A tensile coil spring 4 serving as an exciting member is supported by the hook 12 of an upper unit at one end, and it is supported by the hook 15 of the cam 3 at the other end. The spring 4 applies the exciting force in the axial direction of a coil. When the upper unit is opened, the spring 4 is not wound on the cam 3 at the position of (r) from the center of a sliding cam shaft 6 to apply the exciting force to the cam 3. As the upper unit is closed, the spring 4 is wound around the cam 3 at (r) from the center of the shaft 6 to apply the exiting force to the cam 3. The increment of the rotating force of the cam 3 when the upper unit is opened is reduced to be smaller than when the upper unit is closed.

IPC: G03G15/09
Filed: 1991-02-05
Abstract: PURPOSE:To surely execute bristle cutting for preventing the color mixture of plural developing devices which are provided around one photosensitive body by providing a means for detecting whether or not developing bias voltage is impressed on a conductor. CONSTITUTION:The electric conductor 21 is provided at the edge of the exit side of the aperture of the developing part of the casing 13 of the developing device so that it may be close and opposed to a developing sleeve 12. Since the developing bias voltage is impressed on the sleeve 12 by a DC power source 20, the voltage is applied to the conductor 21 in the case that a developer layer exists between the conductor 21 and the sleeve 12. In the case that a range where the developer does not exist on the sleeve comes to the position of the conductor 21, the voltage is not applied to the conductor 21. Therefore, whether or not the developer layer exists at the position is detected by detecting whether or not the voltage is impressed on the conductor 21 by a voltage impressing detecting sensor 22.

Title: Large monolithic thermal ink jet printing head
Inventor: UIRIAMU JII HOOKINZU
IPC: B41J2/16
Filed: 1990-01-23
Abstract: PURPOSE: To minimize both problems of fragile ink channel due to anisotropic etching and undercut due to erroneous orientation by forming a segmented reservoir and isolating adjacent through recesses by dividing walls thereby strengthening a print head upon increase in the number of nozzles. CONSTITUTION: Via patterns fabricating a linear series of etched through recesses 24 having open bottoms serving as individual ink inlets are separated from each other and individual reservoirs are formed while being separated by dividing walls 46. Opposite surfaces of the dividing walls form a part of adjacent reservoirs, respectively. A linear series of reservoir forms a segmented reservoir 22 and each segment 24 is an etched through recess. Individual recesses 38 in a thick film layer 18 provide individual adjacent ink channels for supplying ink of different colors to each segment. The segment recess strengthens a print head and suppresses the effect of angular misalignment between a mask and the crystal face of a channel plate water.
