Title: Handwritten character recognition/input device using automatic character frame
Inventor: TOGAWA FUMIO
IPC: G06F3/0488
Filed: 1987-11-25
Abstract: PURPOSE:To easily perform the deletion and addition of characters just with operations of a pen and with no use of a keyboard by using a detection means which detects that the pen crosses the line forming a character frame. CONSTITUTION:A tablet 3 and a display part 4 are connected to a word processor main body 5. A CPU included in the main body 5 decides the deletion of character frames (b) and (c) in case the character frames 8 are set horizontally for the horizontal writing purpose and the tip of a pen 2 crosses the frames (b) and (c). Thus the CPU deletes both frames (b) and (c) and the characters displayed in these frames. While a new character frame is inserted between the frames where the tip of the pen 2 crosses in case the pen 2 crosses vertically the train of frames 8. Thus, it is possible to delete and add characters with simple operations of the pen 2 and with no use of a keyboard.

Title: Liquid crystal display device
Inventor: SHIMADA TOSHIO
IPC: G02F1/136
Filed: 1994-11-30
Abstract: PURPOSE: To suppress the reflection in the light shielding layer of a liquid crystal display device, to obviate the disturbance in visual recognition by reflected light and to improve a display grade. CONSTITUTION: An auxiliary capacitor electrode 11 consisting of an ITO (indium tin oxide) is formed over the entire surface and the light shielding layer 12 consisting of Cr is formed on this auxiliary capacitor electrode 11 and is subjected in this state to baking at about 400 deg.C, by which low-reflection CrO2 is selectively formed at the boundary between the auxiliary capacitor electrode 11 and the light shielding layer 12. As a result, the reflection of the ambient light entering from below a TFT (thin-film transistor) array substrate is suppressed and an easily visible screen is obtd. Since the liquid crystal display device is produced merely by adding a baking stage, the production cost is low.

Title: Writing head of automatic drawing machine and its lead supply
Inventor: OIKAWA HIDEAKI
IPC: B43L13/00
Filed: 1990-10-31
Abstract: PURPOSE:To ensure that following leads can be supplied without a special device by arranging a chuck ring which opens/closes a chuck holding a lead in a holder, and providing a knocking device interlocked to the chuck behind the chuck ring and a slider holding a lead forward of the ring. CONSTITUTION:If an arm 30 is moved upward and a knocking part 20 is pressed against a knocking member 40, a knocking tube 8 advances resisting the repulsive force of a knocking spring 9 and at the same time, a chuck 7 advances. As a result, the chuck becomes disconnected with a chuck, ring 6 and then becomes spread open. In this case, a lead L2 drops by its own weight from a lead tank, coming contact with a lead L1. Next, the arm 30 is moved downward, releasing a knocking operation. Subsequently, the chuck 7 becomes closed, holding the lead L2. After that, if a slider 4 is moved backward, the lead L1 protrudes from the tip of the slider 4 resisting the friction of a lead holding member 5. Then if the slider 4 is returned to its home position, a gap generates between the leads L1 and L2. If the knocking tube 8 is pressed, the chuck 7 becomes spread open and the lead L2 drops by its own weight by the gap. Next, if a knocking action is released, lead extraction operation is completed.

IPC: B65H45/101
Filed: 1990-11-02
Abstract: PURPOSE:To form a small, inexpensive sheet folding device for a small, medium size printer by providing sheet guides on the face and back of continuous sheets and a reflected-type photosensor to detect whether the continuous sheets have contact with the lower end of the sheet guides or not.

Title: Signal processing circuit
Inventor: ARISAKA KATSUMI
IPC: H03K17/62
Filed: 1990-11-02
Abstract: PURPOSE:To suppress switching noise by setting an operating current source at the power supply side of a changeover circuit switching operating currents at the ground side of two differential amplifiers with a control signal with the same signal for a current source at the ground side. CONSTITUTION:When the resistance of resistors RE, RF is set as RE=RF/2, a current flowing to the resistor RE is not constant, but a current flowing to the resistor RF is fluctuated synchronously therewith. Moreover, assuming a current flowing to the resistor RE as I(RE) and a current flowing to the resistor RF as I(RF), then the relation of I(RE)=2.I(RF) is established, and the relation of I(RE)=2.I(Q5C) is established and switching noise generated in an output signal Vout is suppressed. Thus, the generation of a DC offset is prevented thereby suppressing switching noise generated in the output signal.

Title: Driving controller for fixing device
Inventor: YAMAMOTO SHOZO
IPC: G03G15/20
Filed: 1987-11-27
Abstract: PURPOSE:To restart a device by providing a detecting means which detects whether both rolls are in pressure-contacting condition or not and an auxiliary starting means which enlarges a torque when a motor is started when both rolls are brought into pressure-contact and halted. CONSTITUTION:It is detected whether a heat roll 31 and a pressure roll 32 are in the pressure-contacting condition or not by means of a microswitch 60. In case of the pressure-contacting condition, a control circuit 61 turns a relay 62 into on-state, and connects a starting capacitor 63 to a driving capacitor 58 in parallel. Capacitor capacity when a driving motor 36 is started is decided as the sum of the capacitors 58 and 63. Thus the motor 36 starts rotating with a torque larger than an ordinary starting torque and smooth restart becomes possible even if the rolls 31 and 32 are in pressure-contacting condition. After the specified time passes, the circuit 61 turns the relay 62 into off-state, and ordinary condition is reset.

Abstract: PURPOSE:To prevent disarrangement of sheet material on a tray, the occurrence of a drop, and disturbance of a loading order by a method wherein a press means brought into pressure contact with the outer peripheral surface of a roller at three spots or more along the direction of an axis is provided, and the pressure contact position is brought into a non-linear state on the outer peripheral surface of a roller. CONSTITUTION:A pressure contact means 3 brought into pressure contact with an outer peripheral surface 1a of a roller 1 at three spots or more along the direction of an axis is formed with a plurality of leaf springs 3a-3d secured to a support part 4 and a plurality of rollers 3e-3h forced into pressure contact with the outer peripheral surface 1a of the roller 1 through the energizing force of the leaf springs. The rollers 3e-3h are brought at (a) into non-linear pressure contact with the outer peripheral surface 1a. Thereby, a discharge angle is different between the inside and the outside of a sheet material P, and high rigidity is provided for the sheet material, which is discharged to the downstream side A as it is curved in a mountainlike manner along the discharge direction of the sheet material P. When the rear end of the sheet material P passes through the roller 1 and the pressure contact means 3, it is placed on a tray 6. By deforming the whole of the sheet material and providing high rigidity, wrinkle and breakage are prevented from occurring to the sheet material, and rounding is prevented from occurring, and disarrangement and the drop of the sheet materials on the tray, and disturbance of a loading order can be prevented.

Title: Developing roll
Inventor: SAKOJIRI HIROMICHI
IPC: B41J13/02
Filed: 1991-10-18
Abstract: PURPOSE:To improve the dimensional accuracy of ruggedness of a sleeve so as to improve image quality by forming a film by ion sputtering on the micro- rugged surface of the sleeve. CONSTITUTION:The film 4 by the ion sputtering is formed on the micro-rugged 2 surface of the sleeve 3 of the electrophotographic developing roll having the sleeve 3 formed with a magnet roll 1 and the micro-ruggedness on the surface. The metallic film or ceramic film 4 can be formed uniformly at 0.2 to 1.2mum thickness in the case of formation of the film by the ion sputtering on the micro-ruggedness 2 of the sleeve 3. Since the film thickness is small in such a case, the effect of the micro-ruggedness formed by sand blasting, etc., can be maintained and, therefore, the image quality is improved. Since the film formed by the ion sputtering fluctuates less, the dimensional tolerance over the entire part of the sleeve does not increase in spite of the presence of fluctuations in metal working at the time of forming the sleeve. Then, the dimensional accuracy of the ruggedness of the sleeve is less affected and, therefore, the image quality is improved.
