Title: Digital notch filter
Inventor: UEENAA PII PETSUZORUTO
IPC: G05D16/20
Filed: 1990-08-22
Abstract: PURPOSE: To eliminate normal state carrier frequency components by sampling the amplitude of information signals at a speed equivalent to a frequency which is the double of the frequency of carrier frequency signal components, adding it to a preceding sample and dividing the respective ones by '2'. CONSTITUTION: A series of control signal samplings are established by sampling feedback control signals by the double of the frequency of carrier wave signals, the respective samplings are added with the preceding sampling by an addition network 54 and a corresponding series of sampling added values are formed. Then the respective sampling added values are divided by '2' by a division network 58 and a corresponding series of feedback control signal samplings from which the carrier wave frequency is filtered usable for oprating a controller 48 are formed.

Title: Position detecting method of unmanned carrying vehicle
Inventor: KAWASE YOICHI
IPC: G01C22/00
Filed: 1984-10-19
Abstract: PURPOSE:To detect both the position and the direction of an unmanned truck by fixing the steering angle and also calculating the distance covered by the truck while two photodetecting parts receive light beams as well as the distance during which the truck travels between two beams when the truck is driven between two beams. CONSTITUTION:The distance (between a solid line position and a dotted line position) beta1 covered by an unmanned carrying vehicle 2 is calculated while two photodetecting members 6 and 7 receives the beams respectively when the vehicle 2 passes through light beams 4 and 5. In addition, the distance beta2 where the vehicle 2 travels between both beams 4 and 5 is calculated. In this case, the steering angle of the vehicle 2 is kept constant. Therefore, the traveling angle of the vehicle 2 to the beams is calculated from the traveling time and speed of the truck between two points A and B as well as the distance between photodetecting switches 11 and 11. Then a circle curvature radius of the traveling track is obtained from a sine theorem of triangle and both distances beta1 and beta2. Thus the position and the direction of the vehicle 2 can be calculated.

IPC: G02B7/02
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To reduce the core dislocation, the inclination or the like of a lens by providing a lens pressing member with a fitting part performing positioning by fitting it with a lens barrel. SOLUTION: The fitting part 1b of a lens barrel 1 is arranged coaxially with the lens fitting part 2b of the lens barrel 1 and the abutting part 2c of a lens pressing ring 2 coaxially abuts on a lens 3 by fitting with the fitting part 2b. Namely, the lens 3 is coaxially pressed by the abutting part 2c and held in proper posture without deviation and inclination with respect to a specified optical axis. Since the fitting part 1b of the lens barrel 1 is fitted to the fitting part 2b of the ring 2 and the fitting part 2b of the ring 2 is attached along the fitting part 1b of the lens barrel 1, the ring 2 is screwed in the lens barrel 1 without causing the inclination. Therefore, when the lens 3 is fixed by the ring 2, it is prevented from being fixed eccentrically to the optical axis of the lens by the clearance, the frictional resistance, etc., of screw parts 1a and 2a.

Title: Integrated circuit
Inventor: YOSHIMURA OSAO
IPC: H03K3/03
Filed: 1986-09-19
Abstract: PURPOSE:To make the monitoring of the AC characteristic of an integrated circuit possible, by constituting a through gate section of multiple stages of AND gates and a feedback section of one stage of NAND gate and wiring. CONSTITUTION:A low is outputted at 'delay value + inter-gate wiring delay values' from the low to high of 'delay values X n pieces + n + 1' fram the high to low of AND gates 1, 2... n. The sum of the delay values is t1. The output of the AND gate (n) is inverted from low to high by a NAND gate (n+1) and fed back to the input terminal of the AND gate 1 and the AND gates 1-n are inverted from low to high similarly to a first operation and outputted from an output terminal B. The sum of the delay values is t2. When the value of the AND gate (n) is larger, the difference between the delay values from high to low and from low to high by means of the NAND gate (n+1) becomes a negligible value and the t1 and t2 respectively represent the delay value from high to low of the AND gate and that from low to high of the AND gate. Therefore, when the value is measured, the AC characteristic of an integrated circuit and delay values from high to low and from low to high can be monitored separately.

Title: Controller for disk motor
Inventor: NARISAWA SADAYUKI
IPC: G11B19/20
Filed: 1985-10-07
Abstract: PURPOSE:To prevent the unreasonable discontinuation of a control to be carried out in a stable state by carrying out said control after confirming the stable state of the revolution of a disk, thereby securing the certainty of said control. CONSTITUTION:The windows WS1, WS3 and WS2 are set successively in the order of the larger width for the detection of the stable state of the revolution of a disk. A window register is set and reset by the corresponding timing sent from a window register control circuit and delivers the signals to show the window areas respectively. The stable state of the disk revolution is detected by a fact whether the synchronizing detecting signal SYNDW is obtained or not with the timing expected for the horizontal synchronizing signal HSYO by means of the window WS for detection of the disk revolution state delivered from the window register. In other words, the stable state is decided when the signals SYNDW are obtained frequency within the window SW. While an unstable state is decided if the signals SYNDW are obtained in a small frequency. Then the control to be carried out in a stable state is discontinued.
