Title: Temperature controller
Inventor: MATSUO TETSUJI
IPC: G05D23/19
Filed: 1988-09-20
Abstract: PURPOSE:To surely raise the temperature to a control target temperature by stopping power supply to a heating element at a set power supply stop temperature and starting the power control of the heating element at the time of detecting the fall of the temperature of an object to be heated by a temperature fall detecting means. CONSTITUTION:When the fall of the temperature is detected by a temperature fall detector 13, a control part 12 waits for the fall of the temperature to a value lower than the control target temperature. When the temperature falls to a value lower than the control target temperature, the control part 12 turns on a switch 2 to restart power supply to a heater 1a, and a heat roll 1 is heated. Next, the control part 12 waits for the rise of the temperature to a value higher than the control target temperature, and the control part 12 turns off the switch 2 when the temperature exceeds the control target temperature. This processing is repeated. Thus, overshoot does not occur at the time of rise, and the temperature is surely raised to the control target temperature.

Title: Method and device for high performance cache arbitration
Inventor: ALBERT J ROBER
IPC: G06F12/08
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To improve the cache efficiency by using the logic which decides whether plural events need the accesses to a cache and outputs a signal to show this decision result, the logic which decides and designates the priority of the events, and the logic that permits the accesses for the events according to their priority. SOLUTION: A performance monitor evaluation part 25 adjusts the priority of a specific component element in response to the signal that is outputted from a register 20. A 2nd component element can access the information included in a 1st component element by reading the data stored in the 1st component element. Otherwise, the 1st component element can automatically send a signal to the 2nd component element. Therefore, the part 25 can access the information stored in the register 20 by reading the register 20 or can automatically send a signal to the part 25. In any case, the priority is changed in order to prevent the exclusive use of a cache.

Title: Array motif evaluation system
Inventor: KONAGAYA AKIHIKO
IPC: G16B40/00
Filed: 1990-09-06
Abstract: PURPOSE:To find out array motif with higher forecasting accuracy by using a value calculated from the description length of array motif expressing the feature part of an array and the accuracy description length of the array motif. CONSTITUTION:The evaluation of the array motif is decided by the sum of description length (a smaller value indicates the simpleness of the array motif) necessary for coding the array motif and description length (a smaller value indicates the higher accuracy of the array motif) necessary for coding an exception at the time of classifying the whole data bank by the array motif. A necessary and sufficient condition for uniform coding is the satisfication of SIGMAi2<->N<i=1 when the length of the i-th code is Ni. When balance between the description length of the array motif and that of the exception is not obtained, the array motif is evaluated by using lambda (description length of array motif) + description length of exception). Provided that lambda is an optional real value.
