Title: Error correction device for bch code
Inventor: NAKAMURA SHINICHI
IPC: H03M13/00
Filed: 1990-07-24
Abstract: PURPOSE:To allow one arithmetic circuit to implement 1-error correction and 2-error correction by setting a coefficient of an error location polynomial of an error location arithmetic circuit to 0 when a BCH code capable of 1-error correction is received and inverting bits of the error location obtained by the said circuit. CONSTITUTION:In the case of making error correction of a BCH code capable of 2-error correction, an error location arithmetic circuit 11 substitutes alpha<-1>, alpha<-2>,... sequentially to X of an error location polynomial sigma(X). In the case of making error correction of a BCH code capable of 1-error correction, a correction signal from an input terminal 10 is 0 and 0 is fed to the error location arithmetic circuit 11. The error location arithmetic circuit 11 substitutes alpha<-1>, alpha<-2>,... sequentially to X of the error location polynomial O(X). Thus, an error of reception codes r30, r29,... is sequentially checked. Thus, the one error location arithmetic circuit 11 implements 1-error correction of the BCH code capable of 1-error correction and 2-error correction of the BCH code capable of 2-error correction.

Title: Air fuel ratio measuring instrument
Inventor: ICHIKAWA NORIO
IPC: F02D41/14
Filed: 1986-08-27
Abstract: PURPOSE:To obtain a signal output corresponding to a theoretical air fuel ratio (lambda=1) being independent from a linear output of a wide range, by forming the titled instrument by a circuit constitution using a differential amplifier, etc., for a comparator. CONSTITUTION:The titled instrument is formed by a circuit constitution using the differential amplifiers 2, 4 for a comparator 5. According to this smile circuit constitution, in a rich area, a pump current Ip flows to a reference electrode 6d (its voltage is Va) from a detecting electrode 6c (its voltage is Vo), therefore, the voltage becomes Vo<Va. Also, a + input and a - input voltage of the comparator 5 for comparing both end voltages of an Ip detecting resistor Rs are connected so as to become Vo and Va, respectively. As a result, a lambda=1 signal output Vlambda from the comparator 5 having a differential amplifying function becomes a high output. On the contrary, in a lean area, the voltage becomes Vo>Va and becomes a low output. According to this circuit constitution, the lambda=1 signal output Vlambda which is brought to a slap variation by a theoretical air fuel ratio (lambda=1) is discriminated from a linear output Vo of a wide range and they can be obtained separately.

Filed: 1994-08-24
Abstract: PURPOSE: To prevent a printed matter from being cut into small pieces by switching the subject of printing to the print data of the highest priority when the printing progresses up to the switching page position that is previously set. CONSTITUTION: A schedule part 38 includes a print propriety deciding part and a data selecting part. The data selecting part selects the divided data that has the highest priority and is to be printed next based on a schedule management table.

The pressurized water is rapidly changed in the direction of flow and the sectional area in elbows 7, 5, 4 and the junctures of the water feed pipe 2 and the discharging pipes 3. As a result, many small vortexes are generated on the inside walls of the discharging pipes in, for example, the junctures of the water feed pipe 2 and the discharging pipes 3. Mixing of the water and the liquid chemical is wall executed by these small vortexes to form fine flocs. Further, the small vortexes are generated along the water flow and the mixing of the water and the liquid chemical is accelerated when the pressurized water mixed with the liquid chemical is discharged from the discharging pipes 3. The fine flocs are thus formed and the purifying capacity is enhanced.

Title: Alarm display system
Inventor: YAMAMOTO HIRONORI
IPC: G06F11/32
Filed: 1981-12-11
Abstract: PURPOSE:To check a failure even if it is of less frequency easily, by storing the state of a failure when it is detected in a nonvolatile memory and reading out and displaying the memory when the power supply is applied. CONSTITUTION:An alarm detection circuit 1 monitors the operating state of a device, detects an alarm based on the generation of a failure, and generates an alarm information signal. A control circuit 2 displays the alarm signal on a display 5 based on the alarm information signal and stores the signal in a nonvolatile memory 4 supported with a battery. The control circuit 2 cuts off a power supply circuit 3 depending on the status. When the failure is restored or the power supply 3 is applied as a test, then the control circuit 2 reads out the alarm information stored in the nonvoltatile memory 4. Thus, the diagnosis of a failure which is naturally disappeared due to the power failure of less frequency can be executed surely.

Title: Decentralized shared memory type multiprocessor system
Inventor: IWASA SHIGEAKI
IPC: G06F15/167
Filed: 1993-08-11
Abstract: PURPOSE:To reduce the traffic of a shared bus and to hold the consistency of a cache in a decentralized shared memory type multiprocessor system consisting of plural processors containing the CPUs, the cache memories, and the partial and shared control parts of a main storage which are connected together via the shared bus. CONSTITUTION:A shared control part 4 includes a main storage tag memory 27 which stores the information on a fact whether the address of its own main memory is stored (shared) in the cache memory of another processor or not (non-shared) and a cache state tag memory 24 which stores the information on a fact whether the data entry of the cache memory is updated and rewritten (dirty) in a shared memory or not (clean). Then a CPU gives an invalidating instruction onto a shared bus to assure the cache consistency as long as a main storage tag is shared when the CPU writes the information in its own main memory. Meanwhile the CPU gives nothing to the shared bus if the main storage tag is not shared and performs the processing in its own processor only. If the cache state tag is dirty to the access request given from another processor unit, the cache consistency is held via the access request.
