  • Patent number: 8111033
    Abstract: The present invention aims to prevent a nonrotation state from being brought about even when a drive allowance is changed by variations in a stepping motor or the like. A pulse down counter circuit outputs pulse down control signal for subjecting main drive pulse to control pulse down when time is counted for a predetermined time period. When a detecting signal exceeding a reference threshold voltage detected by a rotation detecting circuit is detected at a first detection section at start of a rotation detecting time period, a control circuit resets the pulse down counter circuit. Thereby, a main drive pulse generating circuit is not subjected to control pulse down by the pulse down counter circuit, and therefore, it is prevented that the main drive pulse is subjected to pulse down unnecessarily.

  • Patent number: 8071961
    Abstract: A sample measuring method and a charged particle beam apparatus are provided which remove contaminants, that have adhered to a sample in a sample chamber of an electron microscope, to eliminate adverse effects on the subsequent manufacturing processes. To achieve this objective, after the sample measurement or inspection is made by using a charged particle beam, contaminants on the sample are removed before the next semiconductor manufacturing process. This allows the contaminants adhering to the sample in the sample chamber to be removed and therefore failures or defects that may occur in a semiconductor fabrication process following the measurement and inspection can be minimized.

  • Publication number: 20110249536
    Abstract: For a chronograph timepiece that chronograph hands are mechanically reset to zero and electrically driven, the chronograph hands are prevented from being electrically driven while being mechanically locked. A chronograph timepiece that is mechanically reset to zero includes a chronograph motor for driving a chronograph hand, a drive unit configured to drive the chronograph motor according a time measurement operation in response to a starting operation by an operating section, and a control unit configured to control the drive unit. The control unit has a rotation detecting circuit for detecting a rotation status of the chronograph motor. When the rotation detecting circuit detects that the chronograph motor is not rotated after the chronograph motor has been rotated a predetermined time period, driving the chronograph motor by the drive unit is stopped for resetting the time measurement operation.

  • Publication number: 20110122733
    Abstract: A stepping motor control circuit includes a rotation detection portion that detects a rotation condition of a stepping motor, and a control portion that drives and controls the stepping motor by a correction drive pulse P2 having larger drive energy than one of any one of a plurality of main drive pulses P1 each having different drive energy and the respective main drive pulses P1 depending on a detection result of the rotation detection portion. The control portion drives the stepping motor by switching to a fixed drive pulse having drive energy not smaller than drive energy of a main drive pulse P1nmax having maximum drive energy in a case where there is no drive allowance when the stepping motor is driven by the main drive pulse P1nmax having the maximum drive energy. The stepping motor is thus rotary driven normally even in a DC magnetic field.

  • Patent number: 7883418
    Abstract: For reducing the load on a server as much as possible during transfer of data from the server to a terminal, each terminal is capable of playing out a network game in cooperation with a local network game terminal. To this end, the local network game terminal and one or more other network game terminals are grouped in the local network game terminal. Additionally, group information is generated with which the game server 1 can recognize the grouped terminals as one user group, and representative terminal information is also generated with which other network game terminals in the same user group can recognize that the local network game terminal is the representative terminal. Bi-directional communications, including transfer of the data received from the game server 1 and the representative terminal information, are made with other network game terminal(s) in the user group.

  • Publication number: 20110026375
    Abstract: When a stepping motor is driven to rotate by a main driving pulse, if an induced signal exceeding a reference threshold voltage is detected only in a third segment, a pulse down operation is performed, and the main driving pulse is not changed when the same is detected in at least a first and the third segments. When it is detected only in a second and the third segments, a rank-up is performed without performing the driving by a correction drive pulse and, when it is not detected in at least the third segment, the rank up operation is performed after the driving by the correction driving pulse.

  • Publication number: 20110026372
    Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent a non-rotation state at the time of first driving when chronograph measuring operation is reset during motor drive and restarting is effected. When a resetting operation is performed on a reset button during the driving of a motor and a rotation detection circuit detects non-rotation, a drive control unit controls a drive pulse generation circuit such that the control is completed without reversing the polarity of a motor drive pulse output from the drive pulse generation circuit, and that the motor is driven by a drive pulse of the same polarity as that at the time of the previous resetting in response to a starting operation performed on a start/stop button, driving the motor by the drive pulse of the same polarity at the time of restarting after the resetting.

  • Publication number: 20110026370
    Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.

  • Publication number: 20110026371
    Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.
