Title: Quantitizing circuit
Inventor: NARA KIYOYOSHI
IPC: G06K9/38
Filed: 1979-09-26
Abstract: PURPOSE: To obtain different quantitizing information and easily discriminate a character, by changing the threshold which is used in case a photoelectric conversion signal obtained by scanning a character is quantitized, whenever 1 frame of character is scanned.  
     CONSTITUTION: The surface array 2 consisting of photoelectric conversion elements of mxn pieces in the photoelectric conversion part 1 is driven for scanning in order in the line direction and also in the row direction, and a photoelectric conversion signal is sent from the out-put register 4 in order by one line each to the quantitizing circuit 7 under the control of the shift register 3. The shift register 3 sends a frame end pulse to J-K F.F.8 whenever scanning of 1 frame consisting of mxn bit is finished. This F.F.8 changes the threshold supplied to the quantitizing circuit 7 to large and small in order whenever scanning of 1 frame is finished. As a result of the foregoing, both the somewhat thick pattern and the somewhat thin pattern are obtained, and proper discrimination can be performed by selecting one pattern of them depending on the pattern status.

Title: Optical head
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/135
Filed: 1989-05-17
Abstract: PURPOSE:To increase a beam intensity to a medium by providing a means to prevent a beam reflection in the external boundary surface of a transparent material to the transparent material. CONSTITUTION:The reflection of the beam in the external boundary surface of a transparent material 1 is prevented by the reflection preventing means arranged to the transparent material 1. For example, in the external boundary surface of the transparent material 1, when a reflection preventing film 2 is formed on the boundary surface through which the beam passes, the beam is not reflected on the boundary surface, but the most part is guided to a medium 3. When the refraction factor of the transparent material 1 is made to coincide with the refraction factor of a medium surface layer, the reflection factor on the contact surface of the transparent material 1 and medium 3 is substantially made into zero, and the beam is not reflected on the contact surface. Thus, noise components are not superimposed on the output signal of a photodetector, and the phenomenon that the intensity of the beam incident on a tape is lowered because the reflection is generated on each boundary surface can be prevented.

Abstract: PURPOSE: To properly set a control variable of an AGC circuit by selecting a full scanning area or a partial scanning area of a white color part at the left end of a feed roller for valid data range of a read section and calculating the control variable based on read data in the partial scanning range. CONSTITUTION: An image processing unit provides an output of data obtained by sampling read data from a CCD image sensor A in multiple density at a sample-and-hold circuit 42 to an AGC circuit 43. The circuit 43 calculates a coefficient to correct dispersion in the sensitivity and luminance due to the sensor A and element itself of a light source, secular change and temperature change to correct a level of the read data properly.

Thus, the control variable of the circuit 43 is properly set and a shading correction circuit 46 corrects also distortion of the optical system.

Title: Method of underwater detection

IPC: G01S15/96
Filed: 1978-10-09
Abstract: PURPOSE:To accurately detect an object without being affected by interference, by picking out only the first half part of a received signal and recording the picked-out part. CONSTITUTION:Ultrasonic pulses are radiated from a transmitter receiver and reflected on an underwater object. The reflected pulses are received by the transmitter receiver, the output of which is amplified by a pre-amplifier so that a signal (b) is produced. The signal (b) is applied to a phase correlator. The signal (b) and another signal delayed by a half period thereto are superposed with each other so that a correlation output (d) is produced. The output (d) is applied to a delay circuit to generate a delay circuit output (e). These outputs are added to each other by an analogue adder so that a signal (f) with the pulse width of the radiated waves is generated. The signal (f) is amplified by a low frequency amplifier and then recorded on recording paper (s) by a recording pen (p). If there are a plurality of reflected signals and the phase delay of each reflected signal is not less than a half period, only the half parts of the reflected signals are reproduced with the original pulse width, namely, with information on their levels.
