Patent JP-H03289391-A (JP)
Title: Brushless motor
Inventor: TAMAE HIROAKI
IPC: H02P6/17
Filed: 1990-04-04
Abstract: PURPOSE:To provide accurately positioning function and high speed rotatability, to extend a range of fine position regulating after stopping and to reduce current consumption at the time of stopping by advancing the phase of a position signal obtained by a noncontact sensor by a second phase advancer, and energizing a coil by the phase-advanced signal. CONSTITUTION:A noncontact sensor 5 detects the position of a pole tooth of a rotor 7. When an interval of external pulse commands is long, the phase advancing coefficient of a second phase advancer 16 and the value of amplification factor of a processor 14 are altered to vary the slope of a torque distribution near a positioning point, thereby reducing a positioning error against disturbance. If an arbitrary command voltage is applied from a fine position regulating input terminal 19, an amplitude command position signal is phase-advanced by the advancer 16, and the stopping unit of the rotor 7 can be continuously converted according to the value. On the other hand, if an interval of stepping commands is shortened, the output voltage of an F/V converter 15 is increased to become a command of the advancer 16, and the phase advancing amount of a sensor signal becomes larger than that before.

Title: Vdt filter mounting device
Inventor: CHIN SHIYUKEN
IPC: G09F9/00
Filed: 1989-04-10
Abstract: PURPOSE:To eliminate static electricity in a very short time by using a projection provided to a frame so as to make an earth wire adhered to a filter conductive with the filter. CONSTITUTION:A direction of a curved part 42 of a suspension rod 4 being a projection provided to a frame 1 is made coincident with the direction of a slit and inserted into a frame 1 through a hole made to the end. In this state, the suspension rod 4 is turned by 90 deg. and the direction of the suspension rod 42 is made coincident with the direction of the minor axis X of the slot 11. Since the cured part 42 has a size smaller than the size of twice the minor shaft, the curved part is compressed and the suspension rod 4 is fixed to the slot 11. Since the frame 1 is made of a conductive material, the earth wire 5 is kept in the conductive state with the filter 1 via a conductive contact part 10. Thus, the stored charge in the filter 1 is discharged into ground via the earth wire.
Patent JP-H01260501-A (JP)
Title: Control device
Inventor: KANDA MASAE
IPC: G05B9/02
Filed: 1988-04-12
Abstract: PURPOSE:To improve the accuracy of monitor control for a process by stopping the calculation of PID (proportional plus integral plus differentiation) arithmetic constant when an abnormal control variable is outputted from the process. CONSTITUTION:Since no abnormal detecting part 7 is operated when the controlled variable (y) outputted from the process 4 is set within a reference range, a self-turning part 5 is operated normally, then, the PID arithmetic constant is calculated at every constant cycle, and it is set on a PID control part 2. Therefore, the optimum manipulated variable (u) for the process 4 can be obtained by the PID control part 2. Also, when certain abnormality is generated in the process 4 and the controlled variable (y) to be outputted below the reference range is issued, the calculation of the PID arithmetic constant in the self- tuning part 5 is stopped automatically, therefore, the setting of an erroneous PID arithmetic constant on the PID control part 2 can be evaded. In such a way, it is possible to prevent and abnormal manipulated variable (u) from being applied on the process 4, and to improve the accuracy of the monitor control for the process.

Title: System and device for accessing memory
Inventor: HASHIMOTO ETSU
IPC: G06F12/02
Filed: 1989-04-10
Abstract: PURPOSE:To improve speed for accessing a memory by controlling the memory access by using an address memory and an address comparator. CONSTITUTION:When the memory is accessed, address information are stored to an address memory 41 and after the access, the row address input confirmation signal of a dynamic RAM is kept as it is. In the next access, the address information at that access time are compared with the preceding address information, which are stored in the address memory 41, by an address comparator 42. When the both address information are coincident, the memory is operated by a high-speed access system by using only column address information. On the other hand, when the both address information are not coincident, operation is switched to a standard memory access system. Thus, while enabling arbitrary address designation, the memory access can be simultaneously executed at high speed.

Title: High-speed data transfer system between memories
Inventor: NAKAJIMA KENICHI
IPC: G06F13/38
Filed: 1984-05-08
Abstract: PURPOSE:To improve the economization of hardware and the transfer speed by transferring data directly without passing an intermediate memory and executing the transfer of unit data packets at a minimum timing. CONSTITUTION:Each of plural transmission-side memories 11-3 consists of a data memory 3a where data to be transferred is accumulated, an address memory 3b where information indicating reception-side memories of transfer destinations are accumulated, and a FIFO memory 3c where information requesting the data read is stored. Signals on a high-speed data bus 201 connecting transmission-side memories 11-3 and reception-side memories 12-5 are monitored by a specific code (synchronizing flag) pattern detecting circuit 13. When a specific code (for example, 01111110) is detected, a control circuit 14 takes out the request signal of data read from the FIFO memory 3c.

Title: Method of connecting rotating shaft
Inventor: IDETA MITSUGI
IPC: F16D1/06
Filed: 1986-04-21
Abstract: PURPOSE:To firmly connect a rotating shaft and a body of rotation without play, by manufacturing one of the rotating shaft and the body of rotation by means of hard material and manufacturing the other by means of soft material and providing the hard-material-side spline with a sharply projected part, so that the projected part cuts and is pushed into the soft-material-side spline by pressure when both are connected. CONSTITUTION:An inner spline 3 with a predetermined shape is formed on a shaft-core- part of a body of rotation 2 made of steel material that did not take the quenching treatment for the purpose of material-hardening. On the other hand, the entire surface of a rotating shaft 4 undergoes the hardening treatment through quenching. Moreover, an outer spline 5 is formed on the rotating shaft 4 before quenching, and at the predetermined position of the outer spline 5 is formed a projected part 16 along the direction of the tooth-trace by means of knurling. When the body of rotation 2 and the rotating shaft 4 are connected, a knurling-crest 16 of the outer spline 5 cuts and fits itself into the surface of the inner spline 3. As a result, the load is shared by the projected part 16 and its engaging part as well as the spline tooth. Accordingly, the play in the direction of rotation can be eliminated, and the size of the rotating shaft can be reduced for the same load.
