Title: Inverter overload detecting system
Inventor: KOBAYASHI AKIRA
IPC: H02M7/515
Filed: 1978-06-28
Abstract: PURPOSE: To detect overload corresponding to the commutating capacity of an inverter by detecting the overload for the DC power supply voltage.  
     CONSTITUTION: A load current IL is converted into voltage via a current transformer (CT)31 and a resistor 32, and further formed with a DC voltage via diodes 33∼36. This voltage is divided via a resistor 37 and a variable resistor 38, and added to a comparator 41. The voltage divided by resistors 42, 43 from a DC voltage Ed is used as the standard voltage of the comparator 41. When the load current IL becomes overload with respect to the DC voltage at that time, the comparator 41 produces an abnormal signal.

Title: Optical character readre
Inventor: NAKAO KAZUNORI
IPC: G06K9/62
Filed: 1981-05-25
Abstract: PURPOSE:To discriminate following character types to reduce the character error rate, by counting the number of continuous character type identification codes which are set preliminarily. CONSTITUTION:When a form 5 is inserted to a photoelectric converting part 1, it is detected by a photosensor, and one-line components of character string pattern are read. This character string pattern is converted to quantized and normalized data and is stored in a pattern data storage part 2. When one-line components of data are read, a character recognizing part 3 starts recognition of character string pattern data in order from the first character. In the character recognizing part 3, a character type identification character (blank in this example) is discriminated. A character type following the blank is discriminated in accordance with the number of continuous blanks (for example, characters following one blank are alphabet, and characters following two blank are numbers), and the character string pattern is compared with the standard pattern of the discriminated character type. Thus, the character error rate is reduced in sentences where character types are mixed.

Title: Original density detector
Inventor: BISAIJI TAKASHI
IPC: G03B27/72
Filed: 1989-03-31
Abstract: PURPOSE:To precisely detect the relative density between a reference pattern and an original by providing an original pattern and discrimination patterns placed before and after the reference pattern in a direction in which an exposure device exposes the reference pattern and discriminating the reference pattern from the original in response to a change in an output from a sensor, which occurs when an exposed target shifts to the discrimination patter. CONSTITUTION:An exposure light source exposes the discrimination pattern 5, the reference pattern 4, the discrimination pattern 6 and the original in that order by one exposure and scanning, and an optical sensor detects reflected light. The detected output from the sensor rises when an exposed target shifts from the discrimination patterns 5 and 6 to the reference pattern 4 and when it shifts from the discrimination patterns 5 and 6 to the original. In this case, a threshold is set to identify the difference in the detected output between the discrimination patterns 5 and 6, the reference pattern 4 and the original; therefore when the output exceeds the threshold, the shift from the discrimination patterns 5 and 6 to the reference pattern or to the original can be identified. Consequently, an image forming device with a controller that cannot recognize the position of the exposure light source can readily discriminate the reference pattern 4 from the original based on an analog output from the sensor.

Title: Image forming method
Inventor: KUNUGI MASANAO
IPC: G03G15/05
Filed: 1987-03-31
Abstract: PURPOSE:To eliminate ground fogging and to obtain image quality having a high contrast ratio in image formation using a photoconductive toner by providing a stage for forming a uniformly electrostatically charged toner on a conductive substrate and a stage for executing image exposure and installing a gap between the photoconductive toner and transfer body. CONSTITUTION:The uniformly electrostatically charged toner layer is formed on the conductive substrate in the image formation using the photoconductive toner. The image exposure is then executed and the gap is installed between the photoconductive toner corresponding to the formed electrostatic latent image and the transfer body. Transfer paper 6 is installed on the toner layer via a gap material and the ions of the charge reverse from the charge of the photoconductive toner which is not subjected to photoirradiation is generated by a corona charger 7 from the rear face so that the toner is transferred to the paper by the electrostatic force. The charge reverse from the charge of the corona charger is induced in the photoirradiated toner at this time but the charge enough to adhere the toner through the gap to the transfer paper is not induced. The ground fogging is thereby eliminated and the sharp image having the high contrast is easily obtd.

Abstract: PURPOSE: To make it possible to control the abnormal discharge of a vacuum device by providing the output terminals of a power source device having an inverter circuit, rectifier circuit, etc., of a vacuum device with an abnormal discharge voltage detector and controlling the inverter circuit by the output of this detector. CONSTITUTION: The output terminals 21 , 22 of the power source device 1 for the vacuum device 3 having the input circuit 4, primary current rectifier circuit 5 and inverter circuit 6 of AC electric power and a voltage transformer 7 and secondary rectifier circuit 8 for the output voltage thereof and an output filter 12 consisting of a reactor 9, capacitor 10 and a resistor 11 are provided with an abnormal discharge voltage detector 18 consisting of a voltage detector 13, resistor 16 and capacitor 17. The change in the output voltage detected by the detector 18 in the event of the generation of the abnormal discharge is supplied to a control circuit 15. The output of the inverter circuit is converged to a high speed.  The output of the inverter circuit is converged when the overcurrent exceeds the set value of an overcurrent setter, by which the inverter circuit in the initial period of the abnormal discharge is stopped little by little, by which the energy supplied to the vacuum device 3 is gradually decreased and the abnormal discharge is annihilated. The abnormal discharge is thus shifted to the normal fixed voltage.
