Title: Image processor and method therefor
Inventor: TSUJIMURA KAZUKO
IPC: G06T9/20
Filed: 1995-05-22
Abstract: PURPOSE: To prevent overintegration from being caused at an edge break part and perform high-precision area division based upon visual sensation by performing edge connection processing even if there is a break of an edge when an area is divided by using edge information. CONSTITUTION: This processor is provided with an edge communication processing part 13 which performs edge communication processing according to the edge information stored in a memory 12. The processing part 13 generates an edge image from the edge information and then extracts the coordinates of the end points of respective edges from the edge information. For the coordinates of the end points, processing for extending an edge to be extended forward from an end point is performed on the basis of respective coordinate arrays stored as the edge information. And, the newly edge-extended image is updated as the edge image. This processing is performed for all end points and when it is judged that the edge connection processing is completed for all the end points, the edge image which is updated last is regarded as an edge connection processing result image.

Abstract: PURPOSE:To drive a magnetic spring piece significantly with limited energy while enabling a high-speed control by providing a first magnetic pole with a coil for retaining, releasing and controlling a mobile magnetic piece while a vibration current for imparting a vibration force to the magnetic piece to a second magnetic pole to excite. CONSTITUTION:When a magnetic spring piece 15 is retained on a first magnetic pole 11 as a holding current is flowing through a first coil 13, the spring piece 15 vibrates slightly with the end A of the magnetic pole 11 as fulcrum and a wire 6 oscillates vertically with such a fine amplitude as to keep from printing. At the time T1, no current comes to flow through the coil 13 and the spring piece 15 vibrates with the point B as fulcrum to push up the wire 6 significantly. At the time T2, the coil 13 is excited and the spring piece 15 is retained on the magnetic pole 11 to lower the wire 6. At the T3, current in the coil 13 is cut off and the wire 6 is pushed up similarly. At the T4, as current flows through the coil 13, the wire 6 is vibrated slightly again.

Abstract: PURPOSE: To stabilize and continue the operation of a controller by providing a means of turning off a central processor by generating an output signal from a detecting circuit when a supply voltage from a power source circuit deviates from a prescribed range.  
     CONSTITUTION: If a regulated voltage 5V exceeds the upper limit 5.25V of a supply voltage range (n) (Fig. 1) where an electronic control circuit (ECU)6 performs normal operation owing to fluctuations of an unstabilized power source circuit 12V, a fault of a stabilized power source circuit 16, etc., (Fig. a-ii), a voltage applied to the positive input terminal of the 1st comparator COMP 1  exceeds the upper limit voltage 5.25V applied to the negative input terminal, so the comparator P 1  generates a binary coutput 1 (Fig. b-ii) and a gate circuit G also generates a binary output 1 (Fig. d-ii). As a result, a transistor TR turns on to turn on an alarm lamp L, and a reset signal, i.e. 0 is applied to the central processor 6a of an ECU6 through an inverter 19 (Fig. e-ii) to reset the precessor, thus evading maulfunction due to an abnormal supply voltage.

Title: Image reader
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/401
Filed: 1986-05-28
Abstract: PURPOSE:To obtain a superior read image with an appropriate slice level, even it is impossible to perform a pre-scan at a reading time, by performing the pre-scan compulsorily in case of generating a long interval to the next time due to a long time reading operation. CONSTITUTION:A reference white board 1 for the pre-scan, or a document 3 is irradiated by a fluorescent lamp 2. The tip of the document is detected 4 by a sensor DES, and a signal '1' is outputted 4 when the document is present, and the presence/absence of the setting of the document is detected by a sensor DS, and when it is yes, '1' is outputted 5a. After the document is set on a board, it is fed to a position covering the DES, then the pre-scan is performed. Afterwards, it is sent from the DES4 to a reading position by a known distance, and a reading is started. Since it is impossible to decide to which position the document is inserted when the DS5 and the DES4 are covered simultaneously, it is judged as the prescan impossible. When no document arrives at the reading position after a certain reading operation is performed for a prescribed time A, and a prescribed time B elapses, a control means C executes the pre-scan automatically, and an image reading is performed by correcting dispersion(shading) in a light source, or an image pickup system, and always setting the appropriate slice level.

Title: Fm demodulation circuit
Inventor: SHIMOTASHIRO MASAFUMI
IPC: H03D3/00
Filed: 1984-06-15
Abstract: PURPOSE:To suppress the leakage of video FM modulation signal components to a video signal and to demodulate said components by quadrupling carrier frequency through phase shifting circuits, limiter circuits, double wave differentiation circuits, and an adder and separating an original signal at its frequency from the guadrupled modulation signals through an integration circuit to modulate the FM modulation signals. CONSTITUTION:The outputs of the double wave differentiation circuits 5, 6 are thin/ dense pulse waves doubled at their carrier frequency. Since video FM modulation signals of which phases are relatively different each other by 90 deg. over the whole frequency areas are inputted from odd type and even type transversal filters 1, 2 to the circuits 5, 6, the phases of the thin/dense pulse waves are relatively different by 90 deg.. Therefore, the adder 7 adds the thin/dense pulse waves having relatively different phases by 90 deg. and inputs thin/dense pulse waves quadrupled at its carrier frequency to the integration circuit 8. The integration circuit 8 separates the frequency of the video signal from that of the video FM modulation signals and outputs only the video signal. Consequently, the video FM modulation signal components can be prevented from being leaked to the video signal.
