Inventor: KAIDO TSUTOMU
IPC: H02K1/26
Filed: 1993-03-05
Abstract: PURPOSE:To optimize the shape of the teeth of a core and to reduce an iron loss of the equipment by making the shape of the teeth at the core asymmetrical about a face vertical to the driving direction. CONSTITUTION:A rotor of a motor has a permanent magnet 21 and a stator has a core 22 with teeth 23 around which armature coils 26-28 are wound. The shape of the core of the motor is symmetrical about the driving direction and asymmetrical about a face dd', ee', ff' vertical to the driving direction and the core is L-shaped seeing from the direction vertical to the driving direction. Since the rotor is rotated in the direction shown by an arrow 38, current is caused to flow in the armature coils 26-28 so that magnetomotive is generated in the direction shown by arrows 29-31. At that time, the teeth on the side opposite to the driving direction of the movable member has no projection and have the shape 24-24'' of a small curvature and therefore the concentration of a magnetic flux is prevented. By this method, an iron loss can be made small.

Abstract: PURPOSE:To perform the bit error protection of a packet sequence number with simple circuit constitution by containing a sequence number code having an inter-code distance with respect to the packet sequence number in the packet of a packet switching system, and deciding a packet number corresponding to the number code. CONSTITUTION:When a voice packet 60 with the sequence number 0 is transmitted from the transmission origin packet switching unit of a system, it is inputted from a packet input terminal A to a shift register 10 via the transmission path of a switching network, and the sequence number code 50 of the packet 60 is sent from a signal line 100 to a ROM12 for bit error correction. When the ROM12 inputs 000 of the code 50, the address of the ROM12 set in advance is referred, and ROM data 0 corresponding to the address is outputted from a signal line 102 as the sequence number of the packet 60. The sequence number is compared with the one sent from a (m) bit counter 16 at a comparator 18 inputting the sequence number 0, and 0 or 1 synchronized with the sequence number of the packet 60 is outputted. Thereby, it is possible to protect the bit error of the packet sequence number with the simple circuit constitution.

Abstract: PROBLEM TO BE SOLVED: To detect the final stage of cell charging securely and charge a battery satisfactorily regardless of the usage state of the cell and without influences of minute voltage fluctuation, error, noise, etc., in the measurement of the change of a cell voltage. SOLUTION: A cell is charged with a constant current and a charged voltage is sampled every predetermined sampling period. A difference between the sampled voltage sampled one period before and the sampled voltage presently sampled is picked up as a 1st differential voltage. Then a difference between a differential voltage picked up one period before and a differential voltage presently sampled is picked up as a 2nd differential voltage. When the 2nd differential voltage exceeds a 2nd reference differential voltage after the 1st differential voltage exceeds a 1st reference differential voltage, it is detected that the charging is in a final stage. After that, auxiliary charging is carried out to complete the charging.
