Title: Errorneous type detecting method
Inventor: KAMEDA KEIICHI
IPC: H03M13/00
Filed: 1982-06-24
Abstract: PURPOSE:To detect an erroneous type on real-time basis through simple hardware, by comparing a detection signal with error information (uncorrected signal) after correcting operation based upon an error correcting code. CONSTITUTION:The detection signal of an error detector 8 is inputted to an error correcting device 9, which outputs an uncorrected signal. The detection signal and uncorrected signal are compared with other by a comparator 10 to grasp an error type, which is outputted to an output device 11. The comparator 10 compares the number of ''H'' sections of the detection signal per time with that of the uncorrected signal. If an error is random, the detection signal and uncorrected signal has nearly constant transition of their ratio to a time axis, but when a burstlike error occurs, the number of sections of the uncorrected signal is greater than that of the detection signal. Further, both signals are compared, block by block, to detect whether the error of a block is 1 or >=2 bits.

Title: Active sonar equipment
Inventor: YANAGAWA TOSHIYUKI
IPC: G01S7/527
Filed: 1988-05-02
Abstract: PURPOSE:To detect a reflection echo in a large-level reverberation signal by varying the suppression quantity of the reverberation signal received by a TVG amplifier by a variable band stopping filter according to the level of the received reverberation signal. CONSTITUTION:A signal received by a transmitter/receiver contains the reverberation signal in addition to the reflection echo from a target. The level (reverberation level) of the reverberation signal is determined by a transmission level, pulse width, the attitude of the sonar equipment, and the beam width of the transmitter/receiver 1. The level, therefore, varies momentarily, so a filter controller 6 is provided which controls the variable band stopping filter 5 corresponding to the reverberation level. Namely, when the reverberation level is large, the attenuation factor of the center frequency of the reverberation signal of the filter 5 is made large, but when small, the attenuation factor is made small. When the reverberation level decreases below a certain level, the attenuation factor is set to zero. Thus, the attenuation of the reflection echo from the target within a stopped frequency band is reduced to easily detect the target.

IPC: G06K15/00
Filed: 1985-05-22
Abstract: PURPOSE:To enable printing to be performed through free independent conversion of character pattern size and pitch by separating enlarged or reduced characters by a single character unit, determining a character array pitch on the basis of character size and outputting the pitch to a printing section. CONSTITUTION:Characters input from a region designated as a character region by various means such as image sensor are accumulated in a buffer memory 2 by a pattern input section 1. Later, the interior of the buffer memory 2 is scanned by a character separation section 5, separating a character pattern by a single character unit. The separated character pattern is enlarged or reduced by an enlargement/reduction section 3 according to designation information. Then the center pitch of characters is proportionally converted corresponding to the size of character by a character pitch conversion section 6 according to designation information. After this, the characters are printed by a printing section 4. Thus it is possible to enlarge characters without increasing a printing paper or change the size of a printing paper without changing the size of characters.

Title: Lead storage battery
Inventor: YONEZU KUNIO
IPC: H01M2/38
Filed: 1983-06-17
Abstract: PURPOSE:To secure efficient prevention of the stratification of electrolyte by installing a mobile float which can be moved up by a bubble and has a specific gravity larger than that of electrolyte in a tubular body having an upper and a lower opening. CONSTITUTION:A tubular body 1 having an upper opening 2 and a lower opening 3, is installed in electrolyte contained in a storage battery. In the tubular body 1, a float 4 is installed which has a specific gravity larger than that of electrolyte when it is in a charged state and has a homogeneous concentraton. The clearance between the float 4 and the inner side of the tubular body 1 is restricted so that a bubble 5 can not escape over the float 4 through the sides of the float 4. The float 4, being usually sent to the bottom of the internal area of the tubular body 1 due to its specific gravity larger than that of the electrolyte, is moved up when a bubble 2 touches its lower surface. The bubble 5 escapes through the opening 5 when the float 4 reaches a position above the upper opening 2 thereby causing the float 4 to sink in the tubular body 1 again. Thus, the float 4 moves up or down according to the existence of the bubbles 5 so as to cause the electrolyte to flow thereby stirring it.

Title: Soil water purifying device
Inventor: TAMURA TAKAAKI
IPC: C02F3/22
Filed: 1979-08-29
Abstract: PURPOSE: To ensure the supply of a sufficient amount of oxygen to the water to be treated with no reduction of the pH value and furthermore eliminate the installation of a precipitation bath for separation of the active sludge, by using in common both the exposure to air via the high-concentration oxygen gas and that via the air each.  
     CONSTITUTION: The duct 4 is provided to the bath 1 with part of the duct soaked into the solution; and the exposure-to-air sections A and B via the high-concentration oxygen gas and the air each are arranged at the sections partitioned with the cell 4a. Each mechanism of exposure to air consists of a pair of settlers 6 with the bubbler 5. The liquid in the bath flows into the bubbler 5 through the hole 41 to receive the exposure to air via the high-concentration oxygen gas and the air, and then goes up within the bubbler 5 and goes down slowly within the settler 6. The sludge liquid and the supernatant liquid are isolated from each other in the bath, and the supernatant liquid is extracted in the form of the overflow 3. In such way, the accumulation of the CO 2  into the liquid due to the circulating use of the high- concentration oxygen gas can be offset with the common use of the air, thus preventing the lowering of the function of the active sludge.
