Title: Stop position control method for unmanned carrier vehicle
Inventor: USUI TETSUO
IPC: G05D1/02
Filed: 1986-10-30
Abstract: PURPOSE:To improve stop accuracy by finding a detection range from a coil characteristic of a pickup coil for station detection which detects a magnetic field and adding a start point which is a half the detection range and the distance to a point where a stop is made. CONSTITUTION:The detection range DELTAL from a point A of the coil characteristics to a point B where the detector can not perform detection is found by a detector fitted to a driving wheel, the distance DELTAL from the point A to the point B is divided by 2, and the result is added to the distance L from a starting line (c) for a stop to the point (d) where the stop is made. Namely, run distance (x) is L+DELTAL/2, so even if the pickup coil characteristic varies in level, the accurate position of the start line (c) for the stop is obtained at the DELTAL/2 within the detection range DELTAL. Consequently, the stop accuracy is securely improved.

Title: Optical repeater
Inventor: NISHIMURA YOSHIHIKO
IPC: H04B10/079
Filed: 1989-09-29
Abstract: PURPOSE:To design a proper system maintenance plan earlier by providing a means which variously changes the phase of a timing signal supplied to a identifying and reproducing circuit in accordance with the command from a terminal station to detect the code error rate and sends it as a monitor signal to a terminal station. CONSTITUTION:The signal having a low frequency which is obtained by dividing the frequency of the timing signal reproduced by a timing generating circuit 6 by a prescribed frequency division ratio is outputted from a frequency dividing circuit 12, and the phase of the timing signal supplied to a identifying and reproducing circuit 4 is changed with this relatively long period and the degree of modulation designated by the terminal station. A supervisory and control circuit 7 detects the variance width of the code error rate accompanied with the phase change of the timing signal and sends it as a supervisory signal to the terminal station. The terminal station receives this supervisory signal to detect the degree of margin of the identifying and reproducing operation for the phase deviation of the timing signal in accordance with relations between the designated degree of phase modulation and the sent code error rate. Thus, the proper system maintenance plan is made earlier.

Title: Magnetic disk device
Inventor: UCHIDA TOSHIAKI
IPC: G11B33/12
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic disk device which can be made thin and whose controllability is enhanced by a method wherein two series of estimation systems, i.e., the estimation system of the movement of a read/write head actuator and the estimation system of a disturbance which is applied to the read/write head actuator, are provided and the command value of a next segment is decided on the basis of outputs of the respective estimation systems. SOLUTION: A movement estimation system 110 is composed of a feedback circuit which simulates the operation of a voice coil motor VCM which is free of a disturbance and ideal with reference to the input of a command value 143. The actual VCM receives a command value 142, and it outputs a displacement signal via a burst decoder 141. In the movement estimation system 110, the difference signal between an own output displacement signal and the displacement signal from the burst decoder 141 is an internal feedback signal. As a result, a position estimated value and a speed estimated value via a buffer 117 and a buffer 118 are output as movement corrected values. A computing circuit 130 corrects a set value by using the position estimated value and the speed estimated value, and it generates the command value 142 of a next segment.
