Title: Commutatorless dc motor
Inventor: INAJI TOSHIO
IPC: H02P6/08
Filed: 1990-02-09
Abstract: PURPOSE:To improve starting characteristic by counting the time between zero-crossing points of a counter-electromotive forces induced in stator windings, and determining the conduction phases of the windings to be conducted next based on the counted values. CONSTITUTION:A pulse delay means 2 counts a period (n) of a pulse train indicating a zero-crossing point of 3-phase counter-electromotive forces inputted from a counter-electromotive force detecting means 1, and delays an input pulse, for example, by about 1/2 time of the counted period. A logic pulse generating means 3 divides in frequency a pulse (z) outputted from the means 2, and outputs pulses of 6 phases of the same frequency as that of the counter- electromotive force induced in stator windings 11-13. 6-phase pulse signals generated from the means 3 become position signals of a rotor, input to a stator winding power supply means 4, which sequentially supplies driving currents to the windings 11-13 in both directions in response to the rotor position signal outputted from the means 3.

Title: Bracketing test method
Inventor: NAKAKAWARA KIYOUICHI
IPC: H04M11/00
Filed: 1979-03-19
Abstract: PURPOSE:To secure the remote-control test for the data terminal unit from the side of center unit by providing the bracketing test function between the encoder and the data terminal unit to the data terminal unit. CONSTITUTION:When data terminal unit 5 is connected to telephone circuit 2, the test code received the frequency deviation modulation and selection code (a) are transmitted in sequence form the center unit. Code (a) is led to demodulator 52 at unit 5. Selection circuit 53 selects encoder 6 via demodulation output (b) to generate DC voltage (c). On the other hand, test code detection circuit 56 delivers pulse (d) only when both the test code and the selection code are detected correctly. When the gate of AND circuit 58 is closed by pulse (d), voltage (c) is blocked. And the output of circuit 58 features the same state as that under which the DC voltage applied at the starting time time of encoder 6 is shoft-circuited. Accordingly, OR circuit 54 generates continuously the space code corresponding to the short- circuit state. This code is led to modulator 55 to receive the frequency deviation modulation, and the modulated signal is sent to the center unit. And center unit detects the presence or absence of the space code.

Filed: 1989-02-13
Abstract: PURPOSE:To reduce the difference between the temperatures on the inner and outer peripheries of the main shaft bearing and to constrain the thermal deformation of the main shaft by minimizing the variation in the shaft pressure pre-load by passing a coolant into the main shaft of a machine tool, and making the discharging passage of this coolant changeable positively and reversely with the direction of a feeding passage. CONSTITUTION:At the time when a tool for oiling to a shaft center is fitted to a main shaft 4, a solenoid valve 17 is made at a feeding position. Thus, a coolant is flowed in an oblong hole 19 via the hole 20 of a nut 7. At this time, the heat generated by a rear part main shaft bearing 3 and front part main shaft bearing 2 is absorbed. Thereafter, it reaches the external part space of a pull stud 10 from the tip of the oblong hole 19. On the other hand, the coolant flowed to a collet chuck 9 via the oblong hole 22 of a rod 5 by passing a passage C absorbs the heat generated by the bearings 2 and 3 transmitted to the rod 5. The coolant reaching the outer peripheral space of the pull stud 10 via the hole 20 of the nut 7 and oblong hole 19 by passing a passage D and the coolant coming via the oblong hole 22 by passing a passage C are converged inside the collet chuck 9, passed inside a tool holder 11 and flowed out from the tip of the tool.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To manage and control the setting and management of a power saving mode in a centralized way by outputting a control signal designating the power saving mode from a 1st information processor and shifting 2nd information processors into the power saving mode in response to the control signal.

Title: Carrier conveying gripper
Inventor: TOMIZAKI ATSUSHI
IPC: B65G49/07
Filed: 1988-02-12
Abstract: PURPOSE:To simultaneously enable the natural drop of a carrier, when a machine is in emergency stopping, and the impact to a wafer, in the time of chucking, to be prevented by opening and closing a chuck pawl of a conveying gripper in a wafer carrier by a DC motor and a toggle mechanism. CONSTITUTION:A shaft 7 rotates by a motor 11 in the counterclockwise direction till a sensor 17 detects a block 14, opening a pawl 13. While the shaft 7 rotates by the motor 11 in the clockwise direction till a sensor 16 detects the block 14, closing a pawl 3. A trouble is generated halfway conveying a carrier by a gripper, that is, in a position B, even when external force acts on the chuck pawl 3 tending to open, the shaft 7 tends to rotate in the clockwise direction, as the result, the block 14 hits a stopper 12, and the pawl is opened no more. While a rotary speed of the pawl 3, in a position B where it chucks the carrier, is almost zero, and kinetic energy decreases to a minimum of almost zero. Accordingly, the pawl 3, in the time of chucking, decreases the impact given to the carrier 5 to a small level.
