摘要： A pulse width modulation apparatus outputs an output pulse having an arbitrary width with respect to an arbitrary point in a pulse period. A delay means associated with a pulse cycle have multi-stage delay output means. Before a control pulse CLKP is fed to each of multi-stage delay output means, a delay time for the delay output means can be set. A rising or falling to be latched by a latch means is controlled based on delay control pulses obtained by the delay output means. An output pulse having an arbitrary pulse width with respect to an arbitrary point can be supplied without occurrence of an offset pulse or a blank duration at the start of each pulse duration.

摘要： A pulse width modulation circuit apparatus comprises delay gates, delay circuits and an A/D converter. The delay gates are connected in cascade fashion and delay an input clock signal by the same delay time with each delay gate. The delay circuits are furnished interposingly between the delay gates and derive as their common output the delayed clock signal from the delay gates. Because the number of delay gates through which the input clock signal passes is proportional to the delay time acquired, these components constitute a delay circuit arrangement that offers high levels of linearity. With the delay circuit arrangement in use, any one of the delay circuits constituting part of that arrangement is supplied selectively with an operating current as per the digital output from the A/D converter. This provides a delayed clock signal whose delay time matches the level of the input analog signal. Thus there is generated a pulse signal whose pulse width corresponds to the period from the time the input clock signal is given until the delayed clock signal is acquired. This pulse signal has a pulse width of excellent linearity corresponding to the level of the input analog signal.

摘要： A signal detecting apparatus is to obtain hysteresis characteristic at a constant ratio regardless of signal amplitude fluctuations by supplying the threshold level adjusting signal corresponding to the input signal amplitude to the comparison circuit. The threshold value setting signal and the hysteresis adjusting signal is supplied to a comparison circuit through an amplifier and a hysteresis adjusting means having the identical characteristic with the peak hold circuit to set a threshold value and a hysteresis range. Therefore even in the case where the operating characteristic of the amplifier and the peak hold circuit for detecting the peak level of signal amplitude fluctuate, the threshold value and the hysteresis range fluctuation corresponding to the fluctuation. As a result, there can not need the adjustment for resetting the operating characteristic, the threshold value and the hysteresis range in each circuit and thus the time and labor required for adjustment can be further saved.

摘要： A seatbelt retractor integrated with an electronic control unit. A motor is disposed above both side walls of a frame and on the same side as a spool with respect to a back board. The motor is detachably fixed to at least one of the back board and the both side walls and of the frame. The ECU is detachably mounted to an upper stay extending upward from the back board of the frame and to be mounted to the vehicle body. In this manner, the motor and the ECU are integrated with a seatbelt retractor. Since the ECU is mounted to the upper stay, the weight of the ECU is dispersed not only to the main body of the seatbelt retractor but also to the upper stay. Thus, the vibration of the seatbelt retractor may be reduced.

摘要： [Problems] To allow an occupant to easily wear a seat belt without twisting his or her body when the occupant sits in a seat.[Means for Solving the Problems] When a door sensor 60 detects the opening of a door, a motor is driven to wind up a seat belt 2 so as to move a belt guide 4 against biasing force of a spring 9, thereby evacuating the seat belt 2 to a rear side of a vehicle relative to a seat back 1a. When the door sensor 60 detects the closing of the door and a seat sensor 61 detects the sitting of the occupant, the motor is driven in the reverse direction to make a clutch mechanism 34 in the disconnected state so as to protrude the seat belt 2 in the forward direction of the vehicle by the biasing force of the spring 9.
