Title: Method for discriminating text/drawing and half tone
Inventor: BEARSS JAMES G
IPC: G06T5/00
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To improve the plotting of a composite image by judging the presence or absence of the detection of an isolated pixel in one or plural bounded windows in a bit map and processing one selected pixel of the bit map in the bounded window based on the judgment. SOLUTION: A register array 120 is provided with plural detection windows 122, 124, 126, 128 and 130 for detecting the isolated pixel and switching a process on image data. When the isolated pixel is detected in any detection window, a center pixel 136 is template-collated for gray plotting 138. When the isolated pixel is not identified in any detection window, the center pixel 136 is template- collated 139 for text/drawing plotting. Thus, plotting can be switched to template collation 138 of the plotting of half tone and text/drawing plotting 139.

Abstract: PURPOSE:To improve the value of the allowable number of twists and strength, etc. of a wire rod and to obtain the Fe-Ni alloy wire rod having low linear coefficient of expansion by annealing the wire rod before galvanizing it and drawing it again after the galvanizing. CONSTITUTION:An Fe-Ni alloy wire rod having 90kg/mm.<2> strength at a final using condition (after drawing) expected after the change of its strength caused by processing, is annealed to set it to <=6% elongation after annealing.

Title: Video tape recorder
Inventor: UCHIUMI SATOSHI
IPC: G11B27/00
Filed: 1985-01-25
Abstract: PURPOSE:To improve the operability by retrieving a specific picture on the basis of a control signal obtained from a reproduced signal or a control signal corresponding to a prescribed picture to use effectively the control signal recorded by another device. CONSTITUTION:When the control signal is inputted, an index ID signal adding circuit 6 supplies an ID signal having a prescribed frequency to a recording system 1 when a prescribed time elapses after a head switching signal is generated, and this ID signal is recorded on a tape 3. Similarly, an address AD signal is recorded by an AD signal adding circuit 7. When a prescribed ID signal is inputted to a control circuit 12 at a retrieval operation time, a reproducing system 5 rewinds/fast-forwards the tape 3; and when an index detecting circuit 8 or 10 retrieves a designated ID signal, normal reproducing is performed after the tape 3 is stopped temporarily. When a prescribed AD signal is inputted to the circuit 12, the tape 3 is run relatively slowly; and when an address detecting circuit 9 or 11 detects the AD signal, normal reproducing operation is performed.

Abstract: PURPOSE: To provide a titled fabric easily of which only shorter-pile portions are of deep color by a method wherein a deep-colored printing liquid is applied to the back face of a pile fabric having a pile height difference and a light texture color.  
     CONSTITUTION: A pile fabric having a pile height difference and a light texture color is coated on its back face with a printing liquid of a deep color different from the texture color. As a result, shorter-pile portions 2 are all imparted with the deep color while those portions of taller-pile portions 3 which are above the top of the shorter-pile portions 2 retain the light texture color. Thus, deep-color textial printing of only shorter-pile portions, which has conventionally been difficult, can be effected by a simple step and with reduced water consumption.

Title: Solidstate pick up unit
Inventor: CHIKAMURA TAKAO
IPC: H04N5/335
Filed: 1979-02-06
Abstract: PURPOSE: To reduce the leakage current and to increase the resolution, by forming the light shield section at the position corresponding between the electrodes of the major plane to which light is incident.  
     CONSTITUTION: The electrodes are formed on the semiconductor substrate 10, etching is made in mosaic corresponding to the unit number of video elements, and the light shield section 24 is formed, which corresponds to optical black and located among the first electrodes 18, 19 and 19, 20 constituted as circuit element through electric separation. With this constitution, when the light shield 24 is absent, the transversal leakage current is increased as the illuminance of photo electric plane is increased and the resolution is lowered. When the shield 24 is provided, the transversal current and resolution are not changed even with the illuminance of photo electric plane increased. This is because the resolution is determined with the number of video elements of the scanning circuit and transversal leakage current of the photo conductive film. Accordingly, the formation of the shield 24 restricts the leakage current and improve the resolution.

Abstract: PURPOSE:To execute reset without generating a line disconnection, etc., to an opposite device by outputting a trigger pulse when a noise or the hit of a power source is detected, outputting a reset requesting pulse and a selecting signal, and outputting an instantaneous pattern. CONSTITUTION:When the power source noise/instantaneous interruption is detected, a noise/hit detector 1 inputs the trigger pulse to a pulse generator 2. The pulse generator 2 outputs the reset requesting pulse to a terminal 6 and inputs the selecting signal to a selector 4. When the selecting signal is off, the selector 4 outputs the signal at the time of an ordinary action, which is inputted through a terminal 9, to a terminal 10, and when the selecting signal is turned on, the selector 4 outputs the momentary pattern, which is inputted from a pattern generator 3, to the terminal 10. When the reset is completed, by inputting a clear signal from a terminal 11, the output of the pulse generator 2 is cleared, the selecting signal to be outputted to a terminal 7 is turned off, and an ordinary action output is outputted to the terminal 10.
