Title: Cleaning method for electrophotographic recorder
Inventor: IIDA HARUKI
IPC: G03G21/10
Filed: 1986-12-03
Abstract: PURPOSE:To prolong the service life of a blade and to obtain invariably stable cleaning performance by increasing the amount of input toner to a cleaning part right after the end of the cleaning of an effective image area. CONSTITUTION:Cleaning is carried out in the effective image area under normal cleaning conditions and a cleaning preliminary electrostatic discharger PCC2 and a cleaning bias are turned off in a no-image part to increase the amount of input toner to the blade. Namely, turning off the PCC2 and cleaning bias means that the performance of a fur brush is lowered and the amount of input toner to the blade increases. Further, the input toner to the cleaning part is slight in the no-image part, so if an insufficient result is obtained only by turning off the PCC2 and cleaning bias, a developing bias is turned off for a prescribed time to form an untransferred toner image, and the amount of input toner to the cleaning part may be increased in combination. Consequently, the total cleaning life can be prolonged.

Title: Direct drawing type waterless lithographic printing original plate
Inventor: YANAGIDA SHUNICHI
IPC: B41C1/055
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve sensitivity by containing carbon black of specified average particle diameter in a heat-sensitive layer when a direct drawing type waterless lithographic printing block original plate is constituted by laminating successively a heat-sensitive layer and a silicone rubber layer on a base. SOLUTION: When a direct drawing type waterless lithographic printing original plate is constituted by laminating successively a heat-sensitive layer and a silicone rubber layer on a base, carbon black of average primary particle diameter of 15-29nm is contained in the heat-sensitive layer. In the case the average primary particle diameter is smaller than 15nm, transparency is demonstrated in the heat-sensitive layer and laser beams are not absorbed therein with good efficiency, while in the case of being larger than 29nm, particles are not dispersed in high concentration, and the degree of blackness is not increased in the heat-sensitive layer, and similarly the laser beams cannot be absorbed efficiently either. A problem of lowering the sensitivity of a printing block is generated eventually in both above-mentioned cases.  The sensitivity can be improved by the arrangement referred above first.

Title: Monitoring device
Inventor: SAITO MITSUMASA
IPC: H04N7/18
Filed: 1986-12-05
Abstract: PURPOSE:To surely perform monitoring without being perceived by an opponent by operating a monitoring device automatically, by sending a corresponding infrared ray by modulating a prescribed pattern signal, detecting and demodulating the reflected light of a sent infrared ray, and turning ON the power source of a camera, etc., when a demodulated output coincides with the prescribed pattern signal. CONSTITUTION:By modulating a modulated code pattern signal formed at a data encoder 3 at a modulation circuit 4, the corresponding infrared ray is sent from an infrared ray light emitting element 6. When the reflected light of the infrared ray due to a human body 7. etc., is generated, it is received at the infrared ray light receiving element 8 in a demodulation means 8-12, and after it is signalprocessed, it is demodulated at a decoder 12. And the demodulated output of the decoder 12 is supplied to a start up circuit 13 as a comparison means, and is compared with plural demodulated code patterns stored in the start up circuit 13. And when it coincides with a specific pattern out of them, a start up signal is generated, and a power source circuit 14 in a camera part 15, etc., is turned ON. In such way, it is possible to perform accurate monitoring without generating the malfunction.

Title: Automatic radio taxi dispatch system
Inventor: TANI MASATOMI
IPC: H04M11/00
Filed: 1989-11-09
Abstract: PURPOSE:To allow the system to cope with lots of car dispatch requests without increasing personnel expenses by receiving a request call automatically and exchanging information with customers based on a dial number while replying the call with an automatic reply equipment. CONSTITUTION:A call from a public line 2 connecting to a voice entry device 1 is subject to incoming call processing automatically by a reception telephone set 3 and the succeeding sequence control is controlled by a control computer 4 and the reply processing is implemented with customers and taxis 8, 9 by controlling a number registration system 5, an AVM system 6 and a radio equipment 7. Since all the control is processed automatically in this way, the system copes with requests from customers in any case by having only to prepare number of reception telephone lines different from a conventional system not having met the customer's requests because of lack in operator number at a heaviest traffic.

On the other hand, the reproducing operation is switched through a changeovering switches SW1 and SW2 and a deck B operates and reproduces. In the case of contrary, in the same manner as this, the reproducing operation of the deck B is stopped and the deck A reproduces.

Title: Character correcting method
Inventor: MORIYA MASAHIKO
IPC: G06K9/68
Filed: 1992-10-28
Abstract: PURPOSE:To extract a correcting candidate character of high precision and to quickly and easily correct the character by retrieving a character dictionary based on the partial data that is previously registered as the character diction ary. CONSTITUTION:A system consists of a character reader 11 which contains a reading part 12 and a recognizing part 13 for the handwritten characters and numeric characters or the printing rypes and a terminal equipment which is connected to the reader 11 to output the reading result and to correct the misrecognized characters, etc. The character having the partial data on the characters themselves divided vertically or horizontally from a single character is registered in a data base 14 having a dictionary function as a character dictionary 1. In a character correction mode, the dictionary 1 is retrieved in regard to the presence or absence of a character to be corrected and its partial data. Then a correcting candidate character is acquired based on the partial data only when both the character to be corrected and its partial data are recognized. Thus the character can be quickly corrected.

Title: Coordinate value correcting device
Inventor: MITSUYOSHI TSUTOMU
IPC: G06F3/0488
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To correct a line handwritten on a touch panel, etc., without using a complicated operation processing and also with a little memory capacity. SOLUTION: First, coordinates values obtained in a touch panel part are given to a coordinates value acquiring means 3. A coordinates value holding means 5 holds one or two coordinates values corrected in the past. A coordinates value correcting means 4 uses the current coordinates value and the coordinates values obtained from the means 5 and performs correction processing with weighted mean. By doing this, it is possible to maintain drawing quality and to perform correction with a simple configuration because the result becomes mathematically equivalent to that of the case where many coordinates values obtained in the past before correction are weighted and corrected.

Title: Image forming device
Inventor: TAKAOKA KAZUHITO
IPC: G03G15/00
Filed: 1991-10-08
Abstract: PURPOSE:To provide the image forming device where a thin layer of toner can be formed with an even thickness of the layer and without variation in quantity of electrification in image formation utilizing photosensitive toner. CONSTITUTION:A roller 20 is provided in a pressurized contact with a conductive substrate 13 between a toner thin layer forming part (vicinity of sleeve 11) and an exposure part (vicinity of an exposure device 14). Voltage of the same polarity as the electrifying polarity of the toner is impressed to the roller 20, and the surface of the roller is coated by fluororesin, etc., to reduce mechanical sticking force with the toner. Because the thickness and the quantity of the electrification is not even in the toner thin layer formed by the sleeve 11, it is smoothed out by pressure force of the roller 20, and furthermore, while the electrification quantity is made even by impressing the voltage to the roller 20, the toner with high dark conductivity is stuck to the roller 20 and eliminated by the blade 21. Thus, unevenness and fogging of an image can be reduced.
