Title: Priority deciding circuit
Inventor: MATSUDA KOUEI
IPC: H04L29/06
Filed: 1989-02-02
Abstract: PURPOSE:To eliminate the need for the processing to discriminate priority and to miniaturize circuit scale by selecting a control signal in response to the supply state of an instruction signal when the instruction signal with different priority is simultaneously supplied. CONSTITUTION:Plural instruction signals are fed to a processing means 111, which applies processing in response to the instruction signals. The instruction signals are fed also to a selection means 131, which outputs selectively plural control signals generated by a control signal generating means 121 and supplies the result to the processing means 111. In this case, when the instruction signals with different priority are supplied simultaneously, the control signal by the selection means 131 is selected in response to the supply state of the instruction signal. Based on the selected control signal, the processing by the processing means 111 is implemented. Thus, the processing to discriminate the priority of the instruction signals is not required, the circuit scale is made small and the circuit design time is shortened.

Title: Method for inspecting information recording medium
Inventor: KIZAWA MITSUFUMI
IPC: G11B23/00
Filed: 1991-02-19
Abstract: PURPOSE:To reduce inspection result information and to facilitate error analysis by preventing the information error generated during the recording non- permission period after information error is detected from recording while deciding that said error to be generated from is the same cause. CONSTITUTION:When an interpolation error E3 occurs at a reproducing sub-code signal SC from an FEM decoder 14 of an inspecting device main body 11, the occurring position is recorded at an interpolation occurring position recording part 15. On the other hand, a non-permission signal DEN from a recording non-permission signal generated part 20 is supplied to a generating part 15, and the interpolation error E3 to occur during the signal DEN is decided to be the error due to the same cause and is not recorded. Thus, the inspection result information is reduced and the easy and secure error analysis can be performed based on the necessary inspection result information.

Title: Process scheduling system for insuring cpu resource allocation
Inventor: SUZUKI ITARU
IPC: G06F9/46
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To guarantee a service quality of processing that has harsh temporal restriction by satirically allocating CPU resources in advance. SOLUTION: Stream data 13 to be distributed are read to the memory 3 by a prescribed amount at a time from a database 1 (S2). Each stream data 13 read in the memory 3 is equally divided into (n) pieces of split data dd15. A CPU 5 decides stream data which should perform network processing from a stream data group in the memory 3 (S3) and performs network processing of each dd15 in order to distribute stream data to clients (S4). The process scheduling bases on a time sharing system SST, and the TSS divides the CPU processing time into time slices TS and allocates each TS to each process. Then, the CPU 5 performs certain process processing, suspends the processing when the TS passes through and switches processing to another process.

Title: Fan
Inventor: SHIMOIDE SHINICHI
IPC: F04D27/02
Filed: 1982-02-22
Abstract: PURPOSE:To prevent the operating point of a fan from being entered into a super low-frequency  sound generating area and preclude an environmental noise pollution by a method wherein a  sensor detecting amount of information with respect to whirling stall is provided in a casing or  a pipeline and the opening degree of a discharging damper as well as the revolving number of  the fan are controlled by the output of the sensor. CONSTITUTION:Flow amount in a duct 9 is detected by a flow sensor 7 to input the output  thereof into a control unit 8. At the same time, the amount of information or noise, pressure  vibration, speed fluctuation and the like with respect to the whirling stall of the fan 1 is detected by the sensor 10 and the output thereof is inputted into the control unit 8. The output of  the control unit 8 is inputted into the discharging damper 2 by feedback to control the opening degree of the damper 2. In this case, the discharging damper 2 is closed in such a manner  that the amount of airflow is changed along a high-revolution curve H from large to small and  when the operating point of the fan has arrived at the operating point A immediately before  generating the super low-frequency sound, the revolving number of the fan is reduced so that  the operating point of the fan is brought to the point C on a low revolution curve L. By opening the discharging damper 2 in such a manner that the amount of airflow is changed from  small to large, the operating point of the fan may be prevented from being entered into the  super low-frequency sound generating area D.

Filed: 1990-02-07
Abstract: PURPOSE:To arrange many sensors close to one another by providing a first core having a higher refractive index than a clad and a second core having a higher refractive index than the first core. CONSTITUTION:A measuring device 3 for detecting light transmission loss is positioned at one end of an optical fiber 4, and a sensor part 5 as the detection part is set in the middle of the optical fiber 4.
