Title: Electrostatic image amplifying type recording method
Inventor: HOSHINO HIROYUKI
IPC: G03G13/05
Filed: 1978-07-24
Abstract: PURPOSE:To eliminate the need for high voltage is recording control voltage and make possible high-speed recording by amplifying the electrostatic images by the use of the dielectric mesh formed with conduction treated picture on one side to amplify the electrostatic image and forming electrostatic latent images on an insulation-type recording substrate. CONSTITUTION:Charging by a corona generator 24 with charging mesh is performed on a dielectric mesh 21 and the charges corresponding to recording are neutralized by a writing-corona-current pulse generator 25. Next, the corona current is applied by a corona generator 27 from the conductor treating face 23 side of the dielectric mesh 21. Then, the corona current cannot pass through the mesh portions which were not neutralized by the writing-corona-current generator 25 and the corona current passes in the neutralized portions, thus the amplified electrostatic latent images are formed on a dielectric drum 28. Thereafter, developing, transfer and fixing are accomplished by the respective devices. This eliminates the need for high voltage for control voltage or makes possible high speed recording.

Title: Sending method for digital signal
Inventor: KOBAYASHI HIROSHI
IPC: H04B10/556
Filed: 1978-07-21
Abstract: PURPOSE:To widen the allowable range of a reference frequency and also to reduce power consumption by sending digital signals while distinguishing between both pieces of information of ''0'' and ''1'' judging from an interval between two pulses and then by modulating those pulses at a specific frequency. CONSTITUTION:Transmission circuit 1 converts the transmission instruction into a transmission code as shown in the figure, and it is modulated into a photo signal by light emitting diode 3 before being transmitted. At the reception side, the transmitted photo signal is detected by photo diode 4 and sent to reception circuit 2, which decodes the transmission instruction by judging the pulse interval of the transmission signal. For example, it is only required here to judge that the pulse interval of pulses of 2m sec in interval is less than 3m sec at the reception side and that of pulses of 4m sec is more than 3m sec, so that allowable ranges of reference frequencies of the transmission and reception sides.

Title: Asynchronous serial-parallel data converter
Inventor: MIYATA SOUICHI
IPC: H03M9/00
Filed: 1983-05-20
Abstract: PURPOSE:To decrease the data error rate by modulating once an original binary logic signal into a multi-value logic signal to convert a serial-parallel data without requiring a synchronizing clock at all. CONSTITUTION:A multi-value logical modulating section A and a serial-parallel data converting section B are provided. Then, the original binary logic data signal S fed serially is modulated into a ternary logic and ''Nil'' is inserted between data to identify a serial signal. Data signals I1 and I2 from this modulating section A are fed to the converting section B. In this case, any of the data signals I1 and I2 is inverted to the ternary logic to realize the insertion of ''Nil'' simply. Then, a parallel signal is outputted from the converting section B. The serial-parallel data conversion is attained without requiring a synchronizing clock at all, thereby preventing the data signal from being delayed from the clock.

Title: Electrophotographic sensitive body
Inventor: TACHIKI SHIGEO
IPC: G03G5/05
Filed: 1984-05-07
Abstract: PURPOSE:To enable copying and reproduction of a chromatic color by incorporating a coloring matter and/or a dye exhibiting a color in complementary relation to said chromatic color in an electrostatic charge generating layer and/or a charge transfer layer. CONSTITUTION:The coloring matter and/or the dye to be added to the charge generating layer and/or the charge transfer layer, such as a styryl type coloring matter or a nitron type dye, are used in order to lower the sensitivity in a specified wavelength region. The charge generating layer is formed by dissolving such a coloring matter and/ or a dye in a solvent, such as acetone or methanol, coating a conductive layer, and drying it. The charge transfer layer is formed by coating the charge generating layer with a component as the charge generating layer, and drying it. As a result, the charge generating layer and/or the charge transfer layer contains the coloring matter and/or the dye in complementary color relation to the chromatic color, and allows it to absorb light in the wavelength region of the complementary color, resulting in lowering the sensitivity of the photosensitive body to the light of said region, and forming the latent image of this chromatic color part on the photosensitive body. Accordingly, the chromatic color part can be copied by developing the latent image with a developer, and reproduction of black and gray can also be made.

Abstract: PURPOSE:To eliminate the error of measurement caused by the stains on the measurement cell by passing the test sample and air or other liquids through alternately into the measurement cell. CONSTITUTION:Light projectior and receiver 2, 3 are set near the front end of a supporting tube 10 and an air pump 7 is provided at the other end it through the piping. One end of the supporting tube is immersed into the sample liquid.

Filed: 1978-07-26
Abstract: PURPOSE:To provide record on the heaped recording mediums more than two, using a method for the recording on the single medium by speeding up the saturation of ink into the mediums. CONSTITUTION:Using the heaped recording mediums more than three, as a example, the colouring layers are formed in the mediums by saturating the sticked ink on the first medium 2-1 into the second 2-2 and then the third 2-3. For single copy, the quality of record can be held constantly using the platen having a good absorbance for the ink, instead of 2-2 and 2-3. By changing the thickness of 2-1-2-3, it allows the constant quality for simultaneous copy. By so doing, it is possible to record on all of the heaped mediums with the operation for the single recording medium.
