Title: Led exposuring device, image forming device, and method for driving led array
Inventor: SHIRAISHI MITSUO
IPC: B41J2/44
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To form a uniform image by suppressing initial variation of light omission quantities of an LED array by a method wherein the LED array that exposures a photosensitive body is driven by varying a light emission duty by a constant frequency so as to make the light emission quantity constant at the initial stage of the lighting. SOLUTION: An LED head array 101 is equipped with a SELFOC lens array 108 and focuses an image on a photosensitive body 105. A pixel counter 109 is built in an LED array controlling section 102. Image data is read from an image data output section 103 by a trigger signal from a print controlling section 107 and counting of the number of lighting times of the LED array is started, then a light emission duty of the LED array head 101 is gradually varied along with rising of a temperature of the LED array head 101 until the number reaches a prescribed value. When the counted number of the pixel counter 109 becomes the prescribed value, the LED array controlling section 102 stops the controlling of the emission duty. The print controlling section 107 also controls the photosensitive body 105.

The contents are read by the interlace system so that the interlace system video signals of 60 fields/30 framed per second are transmitted. In a receiver 30, odd-field and even-field signals are stored in one of the frame memories 32 and the m'th frame picture is stored in its entirety in the field memory 32, after which these signals are read out. Simultaneously, the (m+1)'th frame picture starts to be stored in the other frame memory 33. Signal reading is performed twice by the noninterlace system for one original one-frame period (1/30th of a second).

Filed: 1989-10-27
Abstract: PURPOSE:To increase a reproducing repeating interval by providing a light phase modulating means in an optical transmitter and providing a means to split an input optical signal into two, means to apply delay difference and means to synthesize the optical signals in an optical receiver. CONSTITUTION:A binary electric signal inputted from an input terminal 1 is converted to the optical signal and sent out to a transmission optical fiber 3. In such a case, a code converting circuit 21 obtains two states to the input signal and each time a space is inputted, the state is inverted. Then, a phase modulating light generating circuit 22 generates the optical signals, which phases are different at 180 deg., according to the output state of the circuit 21 and outputs the optical signal which phase is modulated. Next, the output of the circuit 22 is inputted through the fiber 3 and a light amplifier repeater 4 to an optical receiver 5. In the receiver 5, the input optical signal is splitted by a light splitter 51 and one signal is delayed by a light delay element 52 and synthesized by a light synthesizer 53. Since the signal is directly detected by a photodetector 54, the electric signal with the same pattern as the input electric signal to a transmitter 2 can be stably obtained and the reproducing repeating interval can be increased.

On the other hand, each sound signal transmitter 2 allows a right notice signal reception means 2a to receive the right notice signal. In the case that the received right notice signal gives a right of its own voice output, the radio sound signal transmission means 2b modulates a sound signal from a main body circuit side of the electronic device 3 and sends the signal in a radio wave.  A radio sound signal reception means 1c of the sound signal receiver 1 receives the radio sound signal from the electronic device 3 having the right of sound output. A sound signal demodulation means 1d demodulates the received radio sound signal and allows the speaker 4 to sound the signal via an amplifier 1e.

Title: Delineating method
Inventor: TAKANO YUTAKA
IPC: G06T11/20
Filed: 1984-12-28
Abstract: PURPOSE:To depict a vertical line at a high speed by changing prior to delineation the bit position designating field of the command code of the bit operating command dynamically. CONSTITUTION:The bit operating command included in the bit operating part is altered at the command change part. Then, after the first word is loaded into the CPU register, the bit operation is performed at the bit operating part. The so-operated word is then stored in the original address. Then it is judged whether the operation has come to an end. If the word is the first word, the delineation is terminated. If otherwise, after the next memory address is computed, the process returns to the word load and the above operation is repeated until the operation is terminated. The procedure enables the vertical line to be delineated at high speed since it is unnecessary to judge the bit position and the depiction program is executed with the minimum number of steps once the command code is altered.

Abstract: PURPOSE:To efficiently realize a private school for correspondence correction by filling correction information from a teacher into answer paper by red characters when the answer paper is set in a specified position on a pupil-side. CONSTITUTION:A control circuit 38 executes processing of the private school for correspondence correction. Namely, a teacher transmits examination questions designated by information where an answer area is surrounded by the red characters to the pupil and only answer information written into the answer area is transmitted. Then, the pupil transmits only answer information to the teacher and sets the answer paper in the specified position for recording (recording paper tray). The teacher records answer information received in the paper of the examination problems, corrects them and transmits only correction information. Furthermore, the pupil records only correction information as against the answer which is set in the specified position for recording when there is the transmission indication of correction information from the teacher. Thus, the examination problems, answer information and correction information are transmitted once and the private school for correction by correspondence between the teacher and the pupils can be realized.

Title: Down slope traveling control method for band type unmanned track vehicle
Inventor: KAMATA NAOKI
IPC: G05D13/00
Filed: 1990-10-19
Abstract: PURPOSE:To improve traveling control performance by controlling an unmanned track vehicle within a predetermined sub-slip occurring speed region in front of a down slope, applying a weak brake on the down slope, transferring to nonbrake coasting when the speed drops below the lower limit of the sub-slip occurring speed region, and repeating the operations. CONSTITUTION:An unmanned track vehicle 1 travels on a track 2 while detecting targets 3 at predetermined positions through a target detector 4. A controller 7 receives a target detection signal and a distance signal fed from a traveling speed detector 6 and controls an operating unit 8. Upon detection of approach to a down slope based on the target signal and the distance signal, weak brake is applied so that a sub-slip occurring speed region which may cause a slip (positive slip occurring speed-slip occurring limit speed) is brought about and then the vehicle 1 enters into the down slope. When the speed drops below the lower limit causing slip, transition is made to nonbrake coasting and when the speed exceeds the lower limit causing slip, weak brake is applied again and when the speed exceeds subsequently over the positive slip occurring speed, strong brake is applied. According to the constitution, slip is prevented resulting in traveling with high controllability.
