Title: Exclusive processing system for computer data base system
Inventor: KOBARI KOUJI
IPC: G06F7/22
Filed: 1987-07-13
Abstract: PURPOSE:To reduce the labor needed for the deadlock processing at the user side by checking the possibility of a deadlock when a file is opened and giving the open permission only when no possibility of the deadlock is confirmed even at the record operation. CONSTITUTION:When a file opening request is received from a user and the relevant file is being used, it is decided whether the file can be shared or not. If so, the possibility of 'waiting' is checked. When the possibility of 'waiting' is confirmed, a deadlock is checked at the record level. If no deadlock is confirmed, a file opening process is carried out. While the occurrence of a deadlock is confirmed, the occurrence of this deadlock is informed to the user. At the same time, the deadlock check is carried out at both file and record levels when it is decided the sharing of a file is impossible. Then a waiting process is carried out if no deadlock occurs.

Title: Permanent-magnet rotary electric machine
Inventor: TAJIMA FUMIO
IPC: H02K1/14
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a permanent-magnet rotary electric machine which is reduced in pulsative torque and has a small size and light weight by setting the arranging intervals of adjacently arranged magnetic pole position detectors for different phases at a specific multiple of the arranging width of one stator magnetic poles. SOLUTION: The arranging intervals of magnetic pole position detectors Hu, Hv, and Hw are set double the arranging width of one stator magnetic pole 42. In other words, the detectors Hu, Hv, and Hw are arranged at intervals which are equal to the arranging width of two stator magnetic poles 42. That is, the detectors Hu, Hv, and Hw receive influences form the stator magnetic poles 32 and the magnetic field formed by winding currents at the same (equivalent) level. Consequently, the electric angle of 60$0 between the magnetic poles 42 do not deflect to 50 deg. or 70 deg., but the accuracy of magnetic pole position signals can be secured and the increase of pulsative torques can be suppressed. Therefore, the interval between each detector Hu, Hv, and Hw becomes shorter and the size and weight of a permanent-magnet rotary electric machine can be reduced.
