Patent JP-S61189198-A (JP)
Title: Driving method for stepping motor
Inventor: ENAMI KATSUYA
IPC: H02P8/32
Filed: 1985-02-15
Abstract: PURPOSE:To obtain an accurate stopping angle position of a rotor by providing capacitors between phase windings, discharging at stopping time, thereby increasing a drawing torque. CONSTITUTION:Capacitors C1, C2, C3, C4 for supplying discharge currents to phase windings A-D are connected between the lower ends of the windings A-D. When becoming a stop controlling period, a switching controller 19 detects the stop of the rotation to turn OFF a transistor 14. Thus, a power source voltage is switched from V1 (12V) to V2 (5V). When the phase A is, for example, stopped, charges stored in the capacitors C1, C2 are flowed through other windings B, C, D to the winding A. Thus, the drawing torque of the A phase winding is increased to obtain an accurate stopping position of the rotor.

Title: Frequency dividing circuit for two-rail code
Inventor: KATO MASAKAZU
IPC: H03K21/40
Filed: 1988-02-08
Abstract: PURPOSE:To eliminate the need for external setting and to simplify the operation by providing a self-check function whose frequency division output is a non-code word if a fault takes place in the input or the circuit and raising the circuit automatically from the initial state to the state of a code word. CONSTITUTION:If a permanent fault takes place in the circuit, non-code words '0', '0' or '11' are included in outputs X, X'. Thus, the fault of the circuit is checked by monitoring the outputs X, X'. When the frequency division outputs X, X' in the initial state are non-code words '0', '0' the frequency division output X of the 1st FF 7 is inverted from logic '0' to logic '1' at the leading of the input signal CK. Thus, the frequency division outputs X, X' are set to code words '1', '0'. In case of non-code words '1', '1' the frequency division output X is inverted from logic '1' to logic '0' at the trailing of an input signal CK'. Thus, the frequency division outputs X, X' are set to the code words '0', '1'. Thus, the circuit rises automatically and it is not required to be set externally.

In this case, the inside diameter of an objective 3 for a particle beam is set small, and its distance to the sample 4 is reduced, so that a high- resolution particle beam image is displayed even by a low acceleration voltage. The objective 15 for an optical image is arranged on the backside of the sample 4 to focus the transmission light, so that an optical image having a large visible field can be displayed. Thereby, precision alignment and positional confirmation can be carried out by the use of the optical image, and a defect of a fine pattern or the like can easily be discovered by the help of the high-resolution particle beam image.

Title: Electric blower driving method
Inventor: ARAKI SHIROU
IPC: F04D27/00
Filed: 1980-03-07
Abstract: PURPOSE: To reduce the air blowing stoppage period as possible by cathcing a synchronous motor by means of a semiconductor converter system in a power failure to maintain the synchronous speed running and immediately putting it in parallel to the system, when the power is restored.  
     CONSTITUTION: When a circuit breaker 52M opens with the detection of a power failure of a low voltage relay, the exciting current of a synchronous motor 4 is held constant and the stator blade angle is returend to the starting position. A restoration stand-by push button is actuated to release the gate block which gives out the arc signal of a semiconductor converter system 3. By energizing a start-up relay 8B at this time the output of a speed reference signal circuit 41 increases in the same manner as the acceleration at the normal start-up time. When the synchronous motor 4 approaches the synchronizing speed the output of 41 becomes constant, thus making the speed of the synchronous motor 4 contant. When an AC power source 1 is restored the speed synchronizing relays 15B 1 WB 3  are energized to make synchronized throw-in.
