Title: Control device for motor driven power steering device
Inventor: KAWADA HIDEAKI
IPC: H02P7/03
Filed: 1994-09-22
Abstract: PURPOSE: To provide a control device for a motor driven power steering device, which can detect the failure of a motor current detection circuit. CONSTITUTION: A motor current command value I is applied to a feedback control circuit for the specified period of time T with an ignition key turned op, and current thereby flows to a motor. A motor current value (i) detected by a motor current detector 42 at a time when the specified period of time T0 (T0<T) has elapsed, is inputted into the comparator 23 of the feedback control circuit. A failure detector 32 compares the estimated value Ds of a duty ratio for a PWM signal estimated based on the motor current command value I with the actually measured value of a duty ratio for a PWM signal outputted from the adder 27 of the feedback control circuit to which the motor current detected value (i) has been feedback.  As the result of comparison, when an absolute value of its difference is larger than a specified allowable value ΔD, it is thereby judged that the motor current detector 42 has failed.

IPC: E03D9/00
Filed: 1991-10-01
Abstract: PURPOSE:To offer a toilet seat device which can endure repeated impacts and detect a human body sitting on a seat by certainly distinguishing the human body from a substance. CONSTITUTION:A toilet seat device includes a piezoelectric element 1 attached on a toilet seat, a filter 2 which filters particular frequency components of the output signals of the piezoelectric element 1, an amplifier 3 which amplifiers the output signals of the filter 2, a smoothing means 4 which smoothes the output signals of the amplifying means 3 and a decision means 5 which judges presence and absence of a human body and body motions according to the output signals of the smoothing means 4. Thereby, when a human body sits on the toilet seat, the piezoelectric element 1 which is attached on the toilet seat is deformed by the motion of the human body and outputs voltage signals. The voltage signals are filtered by the filter 2, amplified and smoothed. Presence and advance of the human body, and body motion are judged based on the smoothed signals. Therefore, the toilet seat device can endure repeated impacts and detect the human body sitting on the toilet seat by certainly distinguishing the human body from a substance.

Filed: 1989-09-29
Abstract: PURPOSE:To enable highly accurate detection free from influence of diffracted light with a simple structure by overlapping divided beams to form interference stripes and receiving the beam via a scale having a pattern corresponding to the above stripes. CONSTITUTION:Laser light 1 is split on a wave front by a biprism 3 through a collimator lens 2 to be beams 3a, 3b, which are overlapped to form interference stripes. A scale 4 is formed with the same pattern as the pattern of the interference stripes and with stripe directions in parallel to slit directions on a position where the interference stripes are formed. When the scale 4 is moved toward a direction A, an amount of light incident to a photo detector 5 varies depending on whether bright and dark parts of the interference stripes and light-transmitting and shielding parts of the scale 4 are in a same phase or in a reverse phase. By counting a fluctuation in the amount of light of the detector 5, an amount of relative movement of the scale 4 is detected. Thus highly accurate detection free from influence of diffracted light is possible.
