Title: Syndrome operation circuit for error correction processing
Inventor: TANAKA TOSHIHISA
IPC: H03M13/00
Filed: 1991-06-13
Abstract: PURPOSE:To increase the processing speed by increasing the number of bus lines between a data storage memory and a syndrome operation circuit and processing the syndrome operation in parallel to reduce the data transfer rate between these memory and operation circuit. CONSTITUTION:The number of bus lines between a data storage memory 1 and a syndrome operation circuit 1 is increased to process the syndrome operation in parallel. That is, alpha is defined as the primitive element of a Galois field GF(q<m>) (q: prime number m: natural number), and (k) is defined as a natural number which can divide (n). At this time, (n) information words D0...Dn-1 in every (k) words of the memory 1 are collected to generate a matrix of (k) rows and (n/k) columns. Respective rows are successively or simultaneously inputted to a dividing circuit 6 of (k) polynomials (x-alpha<ki>) from data of (n/k) columns through (k) bus lines. (k) outputs are added after passing multipliers 3, 4, and 5 of (alpha<0>...alpha<(k-i)i>. Thus, the operation is possible with 1/k transfer rate.

Abstract: PURPOSE: To obtain the electrolyte suitable for the titration of a trace of water content in keton especially, by combining the third class butanol and ethanol to the known Karl Fischer electrolyte.  
     CONSTITUTION: The electrolyte suitable for a trace of water content in keton, especially in aceton for the measurement, is obtained with the combination of iodine or iodide, sulfur dioxide, pyridine, chloroform, tertiary butanol and ethanol. As the iodide, potassium iodide and sodium iodide are most suited, and the ratio of the tertiary butanol to chloroform is suited for 1/13W1/2. In determining water content by using the said electrolyte, the said electrolyte is fed to the anode chamber and suitable cathode liquid is added to the cathode chamber and the water content in the anode liquid is removed by power application. Next, the test piece is added to the anode liquid and power application is again made to titrate the water content in the test piece. The electrolytic current in this case is suited around 200mA.

Title: Intake air flow meter for internal combustion engine
Inventor: MIZUTA KAZUYUKI
IPC: F02M35/10
Filed: 1977-11-25
Abstract: PURPOSE: To highly accurately meter the flow rate of intake air with the use of stable vortexes by forming an air chamber, which has communication with an intake air conduit, downstream of this conduit to absorb the reverse surge from the  intake valve side of the engine.  
     CONSTITUTION: The number of Karman's vortexes, which are generated through a vortex generating column 2 in proportion to the air flow rate fed through an intake air conduit 1 into the intake valve of the engine, is measured by ultrasonic transmitting and receiving elements 3 and 4. In case the vacuum in the manifold at the intake valve side is low, the throttle is fully opened to establish no orifice action at the intake valve side so that the reverse surface due to the vacuum will flow through the conduit 1 in the opposite direction. This back flow will not disturb the Karman's vortexes, which are generated by the absorption of such advancing waves due to the reduction in the passing impedance as result from the resonance with an air chamber 6 provided outside of the condiut 1 and having communiation with communication holes 7 downstream of the generating column 2 of the conduit. As a result, it is  possible to measure the flow rate highly accurately with the stable vortexes.

Title: Electromagnetic brake
Inventor: IMAI KIYOSHI
IPC: F16D65/28
Filed: 1979-11-05
Abstract: PURPOSE:To suppress an eccentric magnetic force which acts to a movable core and to prevent a driving rod from jamming, by placing the movable core on a sliding member of nonmagnetic material in all the circumferential gap between the movable core and a yoke. CONSTITUTION:A sliding member 21, which is made of a nonmagnetic material such as copper, copper alloy or synthetic resin, is placed in all the circumferential gap between a movable core 13 and a yoke 17 so that the sliding body 21 is in contact with both the core 13 and the yoke 17 and is mounted on one of them and slides on the other. Another sliding member 16B is interposed between a fixed core 12 and a driving rod 11. Since the gap between the core 13 and the yoke 17 is filled with the nonmagnetic sliding member 21, an eccentric magnetic force is hardly caused due to the nonuniformity of the gap. The eccentric magnetic force which acts to the movable core 13 is thus suppressed to prevent the driving rod 11 from jamming.
