20080262790 | Pedometer - To be able to measure a step number without carrying out an operation processing for selecting a walking sensor in a pedometer using a plurality of walking sensors having sensitivity axes different from each other. OR means converts walking signals inputted in parallel from walking detecting circuits into a synthesized walking signal. CPU calculates the step number by detecting the walking signal inputted to an input port. At this occasion, in detecting the walking signal, CPU alternately carries out a detecting operation of detecting the walking signal and a mask operation which does not detect walking at mask time immediately thereafter at each time of detecting each walking signal. | 10-23-2008 |

20110002197 | Integrated circuit for electronic timepiece and electronic timepiece - In response to a system reset signal inputted into a system reset port, a control circuit sets a general-purpose port to a high level first. Then, when a mode A is set in an integrated circuit for electronic timepiece, the control circuit sets the general-purpose output port to a low level after an elapse of a first time and when a mode B is set, it sets the general-purpose output port to a low level after an elapse of a second time. In this manner, a mode information signal having a pulse width corresponding to the mode is outputted from the general-purpose output port. It thus becomes possible to reduce the size without adding a special configuration for mode confirmation and to perform a confirmation in a short time. | 01-06-2011 |

20110007611 | Chronograph timepiece - In response to an instruction to start time measurement given by a start/stop button, an in-phase drive control unit outputs an in-phase control signal of a predetermined time width to a drive pulse generation circuit such that a stepping motor is driven, instead of by a first drive pulse, by an initial drive pulse of a longer drive time than the drive pulse.

20110013492 | Chronograph timepiece - A chronograph timepiece makes it possible to make sure that it normally operates at the time of an initial starting operation such as system resetting without having to perform a difficult operation or the like. When a system reset signal is input to a system reset terminal and it is detected that initial starting has been effected, a processing unit enables a time hand and a chronograph hand to move after permitting the time hand to perform a predetermined demonstration hand movement when both a start/stop switch and a reset switch have not been simultaneously operated; when these switches have been simultaneously operated, the processing unit enables the time hand and the chronograph hand to move without permitting demonstration hand movement. | 01-20-2011 |

When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity. | 01-20-2011 |
