Title: Method of connecting rotating-machine winding
Inventor: KOJIMA KEISUKE
IPC: H02K3/28
Filed: 1989-12-05
Abstract: PURPOSE:To shorten the length of a connecting conductor at a minimum by adjacently connecting the mutual winding-starts and mutual winding-ends of the two series bodies of windings constituting a parallel circuit and promoting winding in the opposite directions mutually in each series body. CONSTITUTION:Line-side connecting conductors (a), (b) are bonded with a line- side U-phase terminal, and connecting conductors (c), (d) are connected from a neutral-point side X terminal. Two series bodies organizing a parallel circuit are bonded between (a) and (c) and between (b) and (d) respectively. One series body is composed of the windings of u1, u2, u3, u4 in succession, and the other series body consists of the windings of u8, u7, u6, u5 successively. Consequently, since winding is promoted in the opposite directions extending over winding-ends from the winding-starts of the two series bodies, the adjacent windings u1 and u6 and u4 and u5 are connected respectively in the connecting conductors ab, cd on the line side and the neutral point side. Accordingly, the connecting conductors ab, cd can be shortened.

Title: Magnetic disk device, magnetic disk subsystem and their control method
Inventor: HANABUSA HIRONORI
IPC: G11B19/02
Filed: 1994-12-19
Abstract: PURPOSE: To enable read write operations during the process of an acquisition of synchronism and to stabilize the positioning control of a head by controlling the rotational fluctuation during the pull in process and generating only periodic fluctuation within a prescribed range. CONSTITUTION: An SW1 is turned off by the synchronization operation start command from a host control device and an SWA1 is turned on. As a result, the rotational period of a spindle motor 60 is controlled by the period of a reference signal REF'. A synchronizing pull-in reference period generator A20 compares the period of a MIDX signal measured by a period meter A10 with the period of a signal REF outputted from a reference period generator 10 and outputs the signal REF'. A phase control start discriminating circuit A30 detects the fact that the phase difference between the MIDX signal and an SIDX signal becomes within a prescribed range and starts a phase control. Periods and phases of the MIDX and the SIDX signals are compared with each other in a period comparator 10 and a phase comparator 80 and the period and the phase of the SIDX signal of a disk device 2 and the MIDX signal outputted by a reference index generator 1 are made equal and a synchronized operation function is achieved.

IPC: H04M3/00
Filed: 1991-11-28
Abstract: PURPOSE:To shorten the maintenance operation time of the exchange which switches and uses switching control systems by shortening the backup time for switching process history information covering the respective systems. CONSTITUTION:When the start command for maintenance control operation is inputted, the inter-system transfer of the switching process history information is not performed between control parts 101 and 111 and pieces of history information on the systems in memories 102 and 112 for control are written on the hard disks(HD) 104 and 114 of their systems; and further, the HD 104 is replaced with a stand by HD and history information is written from the a memory 102 for control. Then when the end command for the maintenance operation is inputted, an inter-system control part 131 reads the pieces of history information out of the HDs 104 and 114 of the respective systems to a memory 132 for control and compares them with each other, thereby writing one piece of history information after their difference is compensated on the HDs 104 and 114 of the respective systems. The inter-system transfer of the history information is not performed after the start command for the maintenance operation is inputted, and only a minimum amount of data is transferred between the systems after the end command is inputted, so the backup and update time for the history information can greatly be shortened.

Abstract: PURPOSE:To prevent a debugging microprocessor from being stopped by the re-occurrence of bus error during interrupt handling by saving the bus error state, which indicates whether the exception handling due to bus error is executed or not, at the time of the occurrence of interrupt and restoring the save bus error state to a bus error detecting circuit at the time of return from the interrupt. CONSTITUTION:A bus error state storage circuit 4 is provided, and the bus error state indicating whether the interrupt occurs during the exception handling due to bus error or not is saved in the bus error state storage circuit 4 to set a bus error detecting circuit 1 to the bus error absence state before bus error detection at the time of the occurrence of the interrupt from a debugging interrupt request terminal 12, and the saved bus error state is restored to the bus error state storage circuit 4 to the bus error detecting circuit 1 at the time of return from the interrupt. Consequently, the interrupt handling is started in the bus error absence state whether the bus error processing is executed before the start of the interrupt handling. Thus, the debugging microprocessor is not stopped by the re-occurrence of bus error during the interrupt handling.

Title: Cmos input circuit
Inventor: FUJIWARA RYUJI
IPC: H03K19/0185
Filed: 1991-11-29
Abstract: PURPOSE:To reduce a signal propagation delay time between an input and an output by setting a source potential of a PMOS transistor(TR) in an input circuit section to a power supply potential through the conduction of a switch means at the initial state of switch operation and non-conduction after the completion of operation. CONSTITUTION:When a level of an input signal IN changes from an H into an L level, a PMOS TR 13 is conductive and an NMOS TR 14 is nonconductive. Since a potential at a node 16 reaches in advance a power supply voltage VCC) a larger current than that with the case when the potential of the node 16 is less than the voltage VCC flows to the TR 13. Thus, the potential at an output node 12 rises toward an H level rapidly so as to reduce the signal propagation delay time between the input and output after an input signal IN changes till an output signal OUT changes. When the potential at the node 12 rises to some degree, a PMOS TR 18 changes the conduction state and then nonconduction state sequentially.
