Title: Information processor
Inventor: NOTSUYAMA YASUYUKI
IPC: G06F11/22
Filed: 1990-04-24
Abstract: PURPOSE:To execute an inspection test without causing a bus collision even in a vector likely to cause the bus collision by controlling the output of a functional element to a transfer line by a control means different from the control means at the time of the executing processing of an instruction at the time of the inspection test. CONSTITUTION:When a test signal TEST is made high at a first cycle, at a second cycle, a select signal SEL of the output of an F/F 8 becomes high, and a device is turned into a scan-operating state from the second cycle. Since the signal SEL is high from the second cycle to an m-th cycle, the output of AND gates 9a, 9b are selected by selectors 7a, 7b. Since the signal of a low level obtained by inverting the signal TEST by an inverter 10 is given to the inputs of one side of the gate 9a, 9b the output of the gates 9a, 9b are low. Therefore, the signals of the low level are given to the control inputs of bus buffers 3a, 3b. Thus, the outputs of both the buffers 3a, 3b are turned into a high impedance state, and the outputs of both macro-blocks 1a, 1b are not outputted to a bus 4, and the bus collision is prevented.

SOLUTION: Operating conditions of a reactor pressure vessel, e.g. the temperature and the pressure, and then various conditions required for stress analysis are inputted from an input unit 2 and set. The moment for analyzing various stresses over a predetermined time width is set as an analytical condition for each operating condition. Inner pressure stress σa, external load stress σb and thermal stress σc are then calculated at each sampling moment for each part. Subsequently, a combined stress σk (=σa+σb+σc) is calculated at each part and sampling moment for each operating condition and main stresses σ1, σ2 and σ3 are calculated in three axial directions based on the combined stress σk.  Finally, a selected stress difference being employed for calculation of the fatigue accumulation coefficient is extracted based on the variation analysis of stress difference.

Abstract: PURPOSE:To transfer continuously data blocks with high efficiency by adding a state qualifying status to the transfer of data and informing collectively the interruptions for report of reception to a CPU after the reception of the data block. CONSTITUTION:A CPU decides previously the number of bytes designated by a CCW and informs the number of bytes to the CPU by a setting command. At the same time, the CCW consisting of at least a read or write command, a command chain flag, the byte number, a data transfer area, etc. and the CCW consisting of a NOP command, a command chain, a program interruption flag, etc. are chained in plural pieces when a transmission/reception command is produced. An additional information area is set at the data transfer area of the CCW. The CPU counts the transfer bytes during the execution of a command. In case the end of a block is detected within the informed byte number, the transfer of data is carried out together with the additional information showing the valid display of end information, the transfer byte number, the details of errors, etc. Then the transfer of data is through with the input/output device end status and the channel device end status.

Abstract: PURPOSE:To decrease a charging/discharging quantity setting the charge quantity of a bus in charging and discharging equal, by providing an inverter to invert a signal on the bus at a position where the capacity of an address bus is divided. CONSTITUTION:When an address signal Ai with a high level is supplied to an address buffer 31, the buses 41ai and 41bi in the address bus 41i are charged with the high level, and are inverted at the inverter 42, and the buses 41ci and 41di go to low levels. Furthermore, the low levels are inverted by the inverter 43, and the bus 41ei goes to the high level, and a circuit system 44 decodes the low level on the bus 41ci and the high level on the bus 41ei, and selects a cell in a memory cell array 45. At this time, since the cell is selected by a decoder for a data line not shown in figure, the readout or the write of data is performed on the cell. Also, when the address signal supplied to the buffer 31 is the one with the low level, a reverse operation is performed, therefore, the same operation is applied only on a selected cell after all.

Title: Heat insulating method of carried high temperature steel material
Inventor: TAKAHASHI TADAAKI
IPC: C21D9/56
Filed: 1982-06-24
Abstract: PURPOSE:To retain heat of lower face of a steel material preventing damage due to scales from the steel material by arranging many pipes vertically at an interval in the lower part between rollers that carries high temperature steel material. CONSTITUTION:When carrying high temperature steel material such as a steel sheet immediately after hot rolling, many stainless steel pipes 3 are arranged vertically at an interval in a position lower than the carrying level by the rollers 2 under the steel material 1. The stainless steel pipes 3 are thin pipes and their heat capacity is made small by filling with low heat conductive substance etc. or by winding metallic foil on the surface. Radiant heat from the lower face of the high temperature steel material 1 is absorbed by thin metallic parts of the surface of the pipes 3. As their heat capacity is small, they are heated at once to high temperature and radiate the heat to the lower face of the steel material 1. Scales peeled off from the steel material 1 passes through the pipes and do not adhere to the pipes 3. Thus, the pipes can be used for a long time without damage.
