Title: Address converter
Inventor: TATEWAKI MASATAKA
IPC: G06F12/10
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain an address converter which is effective to information processing that is needed for real time by switching a conversion table cache to a conversion table cache which corresponds to new context. SOLUTION: Plural page conversion table caches 13 are switched by a switch 14 according to the value of a context register 12 so that the page conversion table cache for context which is currently processed by a CPU can be used. However, when a page conversion table cache for a context that is about to be processed by the CPU does not exist, it switches to a conversion table cache that has the oldest final reference time among final reference times which are finally referred to by each page conversion table cache respectively. Thus, it switches to a page conversion table cache which is provided with plural caches 13 and corresponds to context that is about to be processed by the CPU.

Title: Time slot management method when separated loop is generated in loop network
Inventor: YAHAGI MITSURU
IPC: H04L12/42
Filed: 1988-06-28
Abstract: PURPOSE:To integrate a closed loop separated in a short time without destroying various kinds of information sets at loop separation by applying data loopback test and recognizing the presence of a separation of each loop in the occurrence of separation loop. CONSTITUTION:If a fault takes place in two positions A, B of transmission lines 47, 49 in a loop network comprising control stations 35, 37 and transmission stations 39, 41, 43, 45 or the like, loopback is applied. That is, separated closed loops C, D are formed and a station 35 being a master station of the 1st closed loop C applies data loopback test to each station. A station 35 recognizes the possibility of the presence of other loop other than its own loop because of the absence of reply from a station 37 through the test. On the other hand, the station 37 being the master station in the 2nd closed loop D recognizes the existence of other loop than its own loop by the similar data loopback test to inhibit a new request of a time slot. Thus, the separated closed loops are integrated in a short time without destroying various information at loop separation.

Filed: 1988-06-28
Abstract: PURPOSE:To integrate separated closed loops in a short time without limitation of restoration job and with less artificial operation by using plural frame headers with different code so as to integrate separated closed loops and to decide a master station. CONSTITUTION:If a fault takes place in two positions C, D of transmission lines 47, 49 in a loop network where control stations 35, 37 and transmission stations 39, 41,43, 45 are connected as a loop by the transmission lines 47, 49, loopback is applied. Then the separated closed loops A, B are formed by allowing each transmission station to use its own station as a loopback station. That is, ends of inner and outer transmission lines of a faulty position are connected to form two closed loops. Then the separated closed loops are integrated by using plural frame headers with different codes attended with the repair of the faulty transmission line to decide a true master station. Thus, the limitation of the restoration job is avoided and the artificial operation is reduced to integrate the separated closed loops in a short time.

Title: Rotating pulse generation circuit of brushless motor
Inventor: FUKUOKA TOSHIAKI
IPC: H02P6/06
Filed: 1990-06-19
Abstract: PURPOSE:To obtain a stable pulse with a simple structure by making a differential amplification circuit using a current mirror circuit of an unbalanced current ratio as an active load instead of a resistor and unbalancing the duty ratio of an output waveform. CONSTITUTION:A position signal waveform (d) appearing on the collector of a transistor 12 is clipped with the VBE of a transistor 14. The current ratio of a current mirror is unbalanced by a resistor 13, therefore, the duty ratio of an output waveform is also unbalanced. A position signal waveform (e) appearing on the collector of a transistor 19 is clipped with the VBE of a transistor 20. The phases of the two waveforms are shifted inversely. The transistors 14 and 20 form a sort of NOR circuit and a waveform transmitted from their common collector is as shown by (f). Two pulses are thus generated every turn of the electrical angle.
