IPC: H04L25/49
Filed: 1995-04-03
Abstract: PURPOSE: To convert the input codes into the code data that include abundant information by deciding the output codes against an input code to be modulated and another input code that is adjacent to the first one from each set of candidates of those input codes based on a prescribed limitation. CONSTITUTION: A data modulation method/device includes a candidate set index decision part 101, a symbol number decision part 102, a postprocessing circuits 106 and 107, an NRZI conversion part 108, an FIFO memory 109, a DC control part 110, and other registers and logic circuits. In such a constitution, a set of plural candidate output codes is decided to every input code. Then an output code that satisfies a prescribed limitation is decided from every set obtained to each adjacent input code. The decided set of output codes can previously contain many types of available codes. Thus it is possible to include abundant information in the output codes in addition to the mere conversion of codes.

Filed: 1993-04-06
Abstract: PURPOSE:To detect an optional data pattern that is previously decided by connecting a logic part which verifies a bit pattern of the received data in parallel to a flip-flop which fetches the received data. CONSTITUTION:A pattern detecting part 10 which inputs the data received from an input gate 1 and a register 2 is connected to a data receiving part which includes the gate 1 to receive data and the register 2 to tempoarily hold the data. Then, the part 10 detects the continuity of bits between data based on the output signal iRCVD(0-9) of the gate 1 and the output signal NEXTD(0-9) of the register 2. For instance, all patterns are detected when logic value '1' continues for 6 bits or more between the continuous data through AND gates 11-15. The outputs of the gates 11-15 are converged by an OR gate 16 and held by a flip-flop 17. Thus, a prescribed optional data pattern can be received and detected with no time lag.

Abstract: PURPOSE:To increase response speed and conversion efficiency by providing intrinsic semiconductor area between P-type area and N-type area of a PN junction type photo diode at a photoelectric conversion part. CONSTITUTION:In a solid state imaging element using a PN junction type photo electrode at a photoelectric conversion part, it has an intrinsic semiconductor area 8 between a P-type area 2 and N-type area 9 of the PN junction type photo diode.

Title: Tank
Inventor: CHIKAGAWA MASAHISA
IPC: B04C9/00
Filed: 1981-05-25
Abstract: PURPOSE: To obtain a tank fitted with a filter which has a high efficiency in trapping fine particles of specified particle diameters and shows a low pressure loss by a method wherein a filter in gas discharge and intake valves for a tank used for storage or in a production process is composed of fluororesin fibers whose fiber diameter, fiber-to-fiber distance, porosity and thickness are specified.  
     CONSTITUTION: The tank has the filter fitted in the gas discharge and intake valves, which filter consisting of a woven and stacked structure of fluororesin fibers having a fiber diameter of 0.01W10μ, a fiber-to-fiber distance of 0.04W40μ, a porosity of 30W 95% and a thickness of 0.02W2mm. The fiber diameter and the fiber-to-fiber distance specified above are required for achieving a trapping efficiency of 80W100% in filtering the particles of a diameter of about 0.3μ, such as bacteria, which have been said to be trappable only at a low efficiency. And, the porosity and the thickness specified above are needed to be effective for decreasing the pressure loss to a desired value. When the fiber diameter and the fiber-to-fiber distance are larger than the respective upper limits, the trapping efficiency is reduced to below 80%, and on the other hand, when the diameter and the distance are smaller than the respective lower limits, the resulted strength is insufficient which leads to an excessive pressure loss. A porosity less than the lower limit leads to a large pressure loss, while a porosity larger than the upper limit results in an insufficient strength.
